A315A

Single Diodes Overview

The Harris Corporation A315A is a single-phase fast recovery rectifier diode designed for general-purpose applications. It features a maximum repetitive reverse voltage of 100 V and an average rectified forward current of 3 A. The device exhibits a maximum forward voltage drop and a reverse leakage current of 3 μA at the rated voltage. It operates within a junction temperature range of -65°C to +175°C and is housed in a bulk-packaged AL-4 through-hole package.

Single Diodes Feature Summary

• Fast recovery characteristics with a reverse recovery time of less than or equal to 500 ns
• High thermal stability supporting operation up to 175°C junction temperature
• Low reverse leakage current ensuring efficient blocking performance

Single Diodes Applications

• General-purpose rectification in power supplies
• Free-wheeling diodes in inductive load circuits
• DC-DC converter output stages

Single Diodes Procurement Notes

Verify the manufacturer designation as Harris Corporation or its successor entities, noting that original Harris Semiconductor assets were acquired by Intersil and subsequently Renesas. Confirm the specific package marking and pinout configuration matches the AL-4 through-hole specification. Ensure the component status is active if new production is required, or verify authenticity for surplus stock given the age of the original datasheet documentation.

Single Diodes Selection Notes

Select this component when a fast recovery diode with a 100 V rating and 3 A continuous current capacity is required. The low reverse leakage and high junction temperature capability make it suitable for environments with significant thermal stress. Compare against modern equivalents from other manufacturers if lead-free compliance or updated packaging options are necessary for the specific assembly process.

Single Diodes Part Context

The A315A belongs to the A315 series of fast recovery rectifiers manufactured by Harris Corporation. This series includes variants with different voltage ratings, such as the A315B for 200 V applications. The series was designed to provide reliable performance in switching power applications before the consolidation of Harris Semiconductor into other corporate entities.
