1N4148-TAP

Single Diodes Overview

The Vishay 1N4148-TAP is a silicon epitaxial planar diode housed in the DO-35 (DO-204AH) axial through-hole package. It features a maximum repetitive peak reverse voltage of 100 V and a continuous forward current rating of 300 mA. The device exhibits a typical reverse recovery time of 4 ns to 8 ns, depending on test conditions, and a junction temperature range up to 175 °C. Packaged in ammopacks containing 10,000 units per pack with 50,000 units per box, it serves as an electrically equivalent alternative to the 1N914 diode.

Single Diodes Procurement Notes

Verify that the specific procurement order explicitly references the TAP packaging suffix to ensure receipt of the correct 10,000-unit ammopack configuration rather than standard reel or bulk variations. Confirm compliance requirements against the latest Vishay material categorization documentation to ensure alignment with current environmental standards before finalizing supply chain agreements.

Single Diodes Selection Notes

Select this component when a robust axial leaded diode capable of handling moderate surge currents is required. The DO-35 package facilitates easy manual insertion and automated placement on printed circuit boards. Ensure the application voltage does not exceed the 100 V breakdown threshold and that thermal management accommodates the specified power dissipation limits under continuous operation.

Single Diodes Part Context

This part belongs to the widely utilized 1N4148 series of small-signal fast-switching diodes manufactured by Vishay Semiconductors. The TAP designation specifically identifies the tape-and-reel or ammopack packaging format intended for high-volume manufacturing integration. It shares electrical characteristics with other industry-standard equivalents while maintaining Vishay's specific manufacturing tolerances and quality controls.

Single Diodes Replacement Considerations

The datasheet explicitly lists the 1N914 as an electrically equivalent diode. When substituting, verify that the replacement component matches the DO-35 physical dimensions and maintains comparable reverse recovery times and peak forward surge current ratings to ensure circuit integrity.

Single Diodes FAQ

What is the difference between the 1N4148-TAP and the standard 1N4148?

The 1N4148-TAP refers specifically to the packaging configuration, which utilizes ammopacks containing 10,000 units per pack. The underlying semiconductor device and electrical specifications remain identical to the standard 1N4148.

Is the 1N4148-TAP suitable for high-voltage applications?

The device has a maximum repetitive peak reverse voltage of 100 V. It is designed for small-signal applications and should not be used in circuits where voltages approach or exceed this limit without appropriate derating.
