Product overview

1N4148W-HE3_A-18 at a glance

1N4148W-HE3_A-18 is the reviewed Vishay AEC-Q101 ordering code for the 1N4148W fast-switching diode in SOD-123. Its 13-inch reel contains 10,000 devices and carries a manufacturer MOQ of 10,000; finish, qualification and reel suffix are part of the purchasing identity.

Key features

Verified device capabilities

Reverse-voltage selection: 75 V DC and 100 V repetitive peak under the Vishay absolute-maximum table.
Current capability for 1N4148W: 250 mA average and 300 mA continuous forward current.
Switching behavior: reverse recovery time is specified at 4 ns maximum under the datasheet test conditions.
Qualification and materials for this exact suffix: AEC-Q101; Halogen-Free No; Vishay Green No; Sn termination.
Package control: SOD-123, two terminals, AH body code, and the documented recommended land pattern.

Applications

Where the device is used

High-speed signal steering and switching where the documented 75 V reverse rating and 4 ns recovery limit fit the circuit.
Clamping, protection and waveform-shaping paths selected within the 1N4148W current, capacitance and surge limits.
Automotive-qualified maintenance builds that preserve the exact SOD-123 footprint and complete 1N4148W-HE3_A-18 order code.

Ordering information

Exact code and packing

1N4148W-HE3-A-18 is retained only as a search/BOM alias; the current 1N4148W manufacturer datasheet directly lists the official purchasing string with HE3_A. PCN DD-002-2025 is not used as evidence for this W variant.

The -18 carrier code means 10,000 pieces on a 13-inch reel; manufacturer MOQ is 10,000. It does not change the electrical die or package.

The order code is listed in the current Vishay datasheet and quality table; no separate unambiguous manufacturer lifecycle label is asserted.

Design notes

Use the rating in context

A loose component marked AH verifies only the 1N4148W/SOD-123 family marking. It cannot establish E3 versus HE3_A, -08 versus -18, date code or shipment lot.

This SOD-123 1N4148W version has 250 mA average and 300 mA continuous forward-current ratings; do not replace it with the smaller WS footprint without review.

Quotation and fulfillment

What is confirmed before an order

Commercial facts belong to the quoted lot. The catalog does not invent live stock, price, date code or lead time.

Exact-part check

Manufacturer, full suffix, package, quantity and requested documentation are captured in the RFQ.

Lot-level quotation

Price, available quantity, date code, condition and lead time are written into the quotation when confirmed.

Inspection request

Label, marking, packing and traceability requirements can be specified before shipment.

Shipping and payment

Shipping method, Incoterm and available payment route are agreed in the commercial offer.

Technical and ordering FAQ

Questions buyers ask about 1N4148W-HE3_A-18

Answers distinguish the IC itself from assembled modules and keep absolute limits separate from normal operating conditions.

What package and body marking does 1N4148W-HE3_A-18 use?

1N4148W-HE3_A-18 uses SOD-123 with body marking AH. The marking is not the full purchasing code.

What does the reel suffix in 1N4148W-HE3_A-18 mean?

It selects a 13-inch reel with 10,000 pieces. The manufacturer MOQ recorded for this exact order code is 10,000.

Is 1N4148W-HE3_A-18 AEC-Q101 qualified?

Yes. HE3_A is the AEC-Q101 ordering option for this reviewed code.

Is 1N4148W-HE3_A-18 Halogen-Free and Vishay Green?

For this exact preferred P/N, the Vishay table records Halogen-Free No and Green No. These values must not be copied from another suffix.

Does this page prove current stock or a shipment lot for 1N4148W-HE3_A-18?

No. The technical and ordering evidence identifies the catalog item. Current stock, date code, price, lead time and lot traceability are confirmed in the quotation.

Catalog relationships
