Diodes Incorporated PR6004-T

Overview

PR6004-T from Diodes Incorporated is a 6.0A fast recovery rectifier diode in TO-220AC package, rated for 400V peak repetitive reverse voltage (V_RRM), 6.0A average forward current (I_F(AV)), and 50ns reverse recovery time (t_rr). It serves as primary AC/DC input stage rectifier in offline power supplies for industrial motor drives and LED lighting ballasts.

For engineers reviewing the PR6004-T datasheet, PR6004-T pinout, PR6004-T application, or PR6004-T equivalent, key selection criteria include V_RRM margin above line voltage peaks, thermal resistance (R_θJA = 50°C/W) under forced-air cooling, t_rr-driven EMI in high-frequency SMPS, and TO-220AC mounting compatibility with existing heatsink footprints.

Technical Context

This device operates as a unidirectional current switch in bridge or single-phase rectifier configurations, with soft-recovery characteristics minimizing voltage overshoot during commutation. Its silicon PN junction achieves low forward voltage drop (V_F = 1.3V at 6.0A) while maintaining tight t_rr tolerance (±10%) across -65°C to +175°C junction temperature range.

The TO-220AC package provides direct metal tab thermal path to heatsink, supporting continuous I_F(AV) derating to 3.6A at 100°C case temperature. No integrated snubber or guard ring - external RC networks required for >100kHz operation in flyback converters.

Key Specifications

FAQ

Is PR6004-T still in active production?

No - PR6004-T is officially obsolete per Diodes document DS26007 Rev. 4. Diodes discontinued the entire PR6001–PR6005 family in December 2020 with no direct replacement. Aetrix Electronics maintains legacy inventory and supports last-time buys with full traceability and lot documentation.

Can PR6004-T be substituted with PR6005-T?

No - PR6005-T is also obsolete and rated for 600V V_RRM, not 400V. Substituting it introduces unnecessary voltage overhead and higher V_F (1.45V), increasing conduction loss by 115mW at 6A. No functional equivalence exists within the discontinued series.

What is the maximum allowable case temperature for continuous operation?

The absolute maximum case temperature is +175°C, but continuous I_F(AV) must be derated linearly above +25°C ambient. At T_C = 100°C, rated current drops to 3.6A per the thermal curve in DS26007. Forced-air cooling extends usable current range beyond this limit.

Does PR6004-T meet AEC-Q101 requirements?

PR6004-T was manufactured in IATF 16949-certified facilities using AEC-Q101-compliant processes, but Diodes did not issue formal AEC-Q101 qualification reports for this specific part number. Automotive use requires customer-level validation per AEC-Q101 test plan.
