There is no single price for every ASIM TVS diode. As of September 28, 2026, ASIM public data sheets provide electrical, pulse, and package information rather than one sales price that applies to every customer, volume, package, tax treatment, and delivery condition.
Direct answer: request a quote for the complete part number and suffix, quantity, packaging, destination, tax basis, required date, and quote-validity period. A price without those fields is not a comparable procurement record.
Why TVS prices differ within one voltage class
“24 V TVS” identifies only part of the component requirement. Cost can change with:
SMA, SMB, SMC, or through-hole package construction;
400 W, 600 W, 1500 W, or another pulse-power class;
unidirectional or bidirectional suffix;
die area, package materials, and production test flow;
reel, tube, sample, or partial-package handling;
order quantity, annual demand, lead time, and shipping method;
required environmental, quality, or project documentation.
The quote must therefore identify a purchasable item, not just a voltage rating.
A 24 V example shows why the part number matters
| Part number | Package | Power class | VRWM | Listed IPP | Quote record needs |
|---|---|---|---|---|---|
| SMA04J24V | SMA | 400 W | 24 V | 10.3 A | Full suffix, pack quantity, delivery basis |
| SMB06J24V | SMB | 600 W | 24 V | 15.5 A | Packaging, volume, and required date |
| SMC15J24V | SMC | 1500 W | 24 V | 38.6 A | Footprint, packaging, and project conditions |
The devices share a voltage class but are not the same BOM item. A price comparison labeled only “24 V TVS” can therefore mix different packages and pulse-current points.
Fields required for a comparable quote
| Field | Required entry | Procurement purpose |
|---|---|---|
| Full part number | Include polarity and other suffixes | Identifies the exact device |
| Data-sheet revision | File and revision | Aligns commercial and engineering approval |
| Quantity | Sample, first order, monthly and annual demand | Aligns quantity tiers |
| Packaging | Full reel, tube, tray, or other | Aligns minimum pack and handling |
| Tax basis | Tax included or excluded | Prevents mixed price bases |
| Delivery | Destination and freight responsibility | Calculates landed cost |
| Lead time | Required date and accepted window | Separates stock and production terms |
| Validity | Quote expiration date | Prevents use of stale prices |
| Documents | Data sheet, environmental and quality evidence | Defines approval deliverables |
Two unit prices are comparable only after these fields are normalized.
Calculate landed cost, not an isolated unit price
A practical batch comparison can use:
Landed cost = tax-adjusted material amount + freight + packaging or split-reel fees + inspection and validation cost + excess inventory caused by minimum packaging.
Currency and payment terms also need a defined date and basis. Do not turn an unconfirmed future exchange rate into a fixed procurement assumption.
Why sample pricing does not establish production pricing
Sample handling, small-quantity picking, and production reels use different commercial conditions. A free engineering sample does not mean production material has zero cost. Separate the stages:
samples establish electrical and assembly suitability;
a first order checks packaging, receiving inspection, and production yield;
a production quote uses stable volume and delivery cadence;
every stage retains its date and validity period.
Technical qualification comes before price ranking
A low price does not make an electrically unsuitable device a valid option. Before comparing quotes, verify that:
VRWM covers the highest continuous circuit voltage;
VC is evaluated with the relevant IPP and pulse waveform;
the protected node remains below its permitted transient limit;
polarity, package, land pattern, and return path fit the board;
leakage, temperature, and post-stress behavior satisfy the application.
If these conditions are not met, rework, requalification, scrap, or excess inventory can exceed the apparent unit-price difference.
How to compare two ASIM TVS quotations
Confirm that both quotations use the same complete part number and data-sheet revision. Normalize quantity, packaging, tax, freight, delivery date, payment terms, and validity. If the part numbers differ, engineering must first complete the cross-reference and sample validation. Procurement price alone cannot approve a technical substitution.
Keep the following evidence with the approval:
original dated quotation;
full part number and archived data sheet;
engineering approval record;
sample lot and verification results;
minimum packaging and expected consumption period;
product-change and exception-traceability requirements.
What public ASIM documentation can establish
ASIM data sheets can verify the quoted part's voltage class, package, pulse rating, and stated test conditions. They are not commercial quotations. Their role in price review is to prevent unlike devices from being placed in one price column.
Frequently asked questions
What is the price of one ASIM 24 V TVS diode?
“24 V” is not enough. The requester must identify the series, package, polarity suffix, quantity, packaging, tax and delivery conditions.
Can a retail listing be used for an annual budget?
It can be a temporary reference, but it may not reflect annual volume, full-reel packaging, freight, tax, or lead-time commitments. Use a dated formal quotation for budgeting.
Does a higher price prove better protection?
No. Protection depends on the exact electrical conditions, device construction, board path, and target transient. Price is not an electrical rating.
