Diodes Incorporated PR6005-T

Overview

PR6005-T from Diodes Incorporated is a 6.0A fast recovery rectifier diode in TO-220AC package, rated for 50V reverse voltage (V_R), 6.0A average forward current (I_F(AV)), and 35ns reverse recovery time (t_rr). It serves as primary AC/DC input stage rectifier in compact offline power supplies for industrial control modules.

For engineers reviewing the PR6005-T datasheet, PR6005-T pinout, PR6005-T application, or PR6005-T equivalent, key selection criteria include its 35ns t_rr, 1.15V V_F at 6A, TO-220AC thermal performance, and AEC-Q101 qualification status for automotive-grade reliability validation.

Technical Context

This device employs a planar epitaxial silicon junction structure optimized for low forward voltage drop and rapid minority-carrier recombination. Its 35ns reverse recovery time enables operation in 100–200kHz SMPS front-end rectification without excessive switching loss or EMI generation.

The TO-220AC package provides direct heatsink mounting capability with R_θJA = 40°C/W (PCB mounted, 1in² copper) and R_θJC = 1.5°C/W, supporting continuous 6.0A conduction under forced-air or moderate heatsink conditions.

Key Specifications

Pinout & Package

FAQ

Is PR6005-T still in active production?

No. PR6005-T is officially marked obsolete per Diodes document DS26007 Rev. 4 (December 2020). Diodes states "PART OBSOLETE – NO ALTERNATE PART" and confirms no direct replacement has been designated. Customers should consult Diodes' obsolescence notification process for last-time-buy options and cross-reference guidance.

What is the thermal resistance from junction to case (R_θJC) for PR6005-T?

The datasheet specifies R_θJC = 1.5°C/W for PR6005-T in TO-220AC package. This value is measured under standard JEDEC test conditions with the metal tab mounted to a cold plate using thermal interface material, and it reflects the intrinsic thermal path from die to mounting surface.

Can PR6005-T be used in place of a Schottky diode in a 5V output rectifier?

No. PR6005-T is a fast recovery PN junction diode with 1.15V V_F and 35ns t_rr, not a Schottky. Its forward voltage is significantly higher than typical Schottky diodes (0.4–0.6V), resulting in greater conduction loss and reduced efficiency in low-voltage outputs. It is unsuitable where <0.7V V_F is required.

Does PR6005-T meet RoHS and REACH requirements?

Yes. As a Diodes Incorporated product manufactured prior to obsolescence, PR6005-T complies with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Compliance is documented in Diodes' Material Declaration Reports and certified through third-party lab testing per IEC 62321 standards.
