BY252GPHE3/54

Overview

The BY252GPHE3/54 is a standard recovery rectifier diode from Vishay General Semiconductor, part of the SUPERECTIFIER series. It features a glass-passivated junction and is housed in a DO-201AD axial package for through-hole mounting. Key electrical parameters include a maximum repetitive peak reverse voltage (Vrrm) of 800 V and an average forward rectified current (Io) of 3 A at 25°C. The device exhibits a typical reverse leakage current of 5 µA at full rated voltage and a forward voltage drop of 1.1 V at 3 A. Its reverse recovery time is specified as 3 µs, with a junction temperature range spanning from -65°C to 175°C.

Feature Summary

• Glass-passivated junction structure provides high reliability and meets MIL-S-19500 standards.
• SUPERECTIFIER design ensures cavity-free construction for enhanced durability under harsh conditions.
• Low leakage current characteristics contribute to improved circuit efficiency.
• High forward surge capability supports robust performance during transient events.

Applications

• General-purpose rectification in power supply circuits
• Freewheeling diode applications in inductive load switching
• High-voltage DC conversion systems

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm RoHS compliance status and packaging type (reel or tape) prior to order placement. Ensure storage conditions adhere to moisture sensitivity level requirements to prevent degradation before soldering.

Selection Notes

Select this component when a standard recovery time of approximately 3 µs is acceptable for the application frequency. The 800 V rating suits medium-to-high voltage AC-DC conversion stages. Compare thermal resistance values against system heat dissipation capabilities to ensure junction temperatures remain within the specified operational limits during continuous conduction.

Part Context

This diode belongs to Vishay's SUPERECTIFIER family, which emphasizes high-reliability glass-passivated silicon rectifiers. The BY252 variant specifically targets 800 V applications, distinguishing it from lower voltage counterparts like the BY251 or higher voltage models such as the BY255 within the same product line.
