1N4148-P-TAP

Single Diodes Overview

The Vishay 1N4148-P-TAP is a silicon junction switching diode belonging to the 1N4148 series. It features a single diode configuration housed in a DO-35 axial leaded package with two pins for through-hole mounting. Key electrical parameters include a maximum average forward current (If) of 300 mA and a peak non-repetitive forward surge current (Ifsm) of 2 A. The device supports a maximum repetitive peak reverse voltage (Vrrm) of 75 V and a maximum DC reverse voltage of 100 V. It exhibits a peak reverse recovery time (trr) of 4 ns, a maximum forward voltage (Vf) of 1 V at specified currents, and a maximum power dissipation (Pd) of 500 mW. The operating junction temperature range spans from -65°C to +175°C.

Single Diodes Procurement Notes

Verify the specific suffix 'P' against official Vishay documentation to confirm if it denotes a specific tape-and-reel packaging format or variant distinct from standard bulk configurations. Ensure the component matches the required DO-35 package dimensions and lead form factors for your PCB layout. Confirm RoHS compliance status directly with the manufacturer datasheet prior to final procurement decisions.

Single Diodes Selection Notes

Select this component when a small-signal silicon switching diode with high-speed characteristics is required for through-hole designs. The 1N4148-P-TAP offers a balance of low forward voltage drop and rapid recovery times suitable for general logic and signal processing applications. Consider the 300 mA continuous current rating and 500 mW power dissipation limits to ensure adequate thermal management within the target circuit environment.

Single Diodes Part Context

This part belongs to the widely utilized 1N4148 family of small-signal switching diodes manufactured by Vishay General Semiconductor. These components are industry standards for fast switching applications due to their reliable silicon junction technology and standardized DO-35 axial package. The product line provides consistent performance across various manufacturing batches, ensuring compatibility with legacy and modern electronic designs requiring discrete switching elements.

Single Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N4148 variants such as those from NXP or Diotec, provided they meet the same 300 mA current and 75 V reverse voltage specifications. Verify that any replacement maintains the 4 ns reverse recovery time and DO-35 package footprint to ensure mechanical and electrical interchangeability without redesigning the host circuit board.
