Diodes Incorporated DSRHD08-13

Overview

DSRHD08-13 from Diodes Incorporated is a glass passivated single-phase bridge rectifier with 800 V peak repetitive reverse voltage, 1.0 A average output current, and 150 °C maximum junction temperature-designed for AC/DC conversion in offline power supplies, LED drivers, and industrial control power stages.

For engineers reviewing the DSRHD08-13 datasheet, DSRHD08-13 pinout, DSRHD08-13 application, or DSRHD08-13 equivalent, key selection criteria include its T-MiniDIP package thermal resistance (R_θJL = 25 °C/W), 30 A non-repetitive surge rating, and RoHS-compliant matte tin terminals suitable for lead-free reflow.

Technical Context

This bridge rectifier integrates four diodes in a single-phase full-wave configuration, enabling direct AC-to-DC conversion without external wiring. It operates across –55 °C to +150 °C and supports 60 Hz resistive/inductive loads with 20% derating for capacitive loads.

Its glass passivation ensures stable reverse leakage (<150 µA at 125 °C) and robust forward voltage performance (1.1 V @ 1.0 A, 25 °C). Thermal design relies on low R_θJL for efficient heat transfer to PCB copper or aluminum substrates.

Key Specifications

Pinout & Package

Package: T-MiniDIP (4-pin, molded plastic, UL 94V-0 rated, 0.092 g weight). Terminals are matte tin over copper lead frame, solderable per MIL-STD-202 Method 208.

FAQ

What is the maximum allowable ambient temperature for DSRHD08-13 at full 1.0 A load?

At 1.0 A average output current, the device requires thermal management to limit junction temperature to ≤150 °C. With R_θJA = 62.5 °C/W on glass-epoxy PCB, maximum ambient is ~87 °C; using aluminum substrate (R_θJA = 62.5 °C/W) raises this to ~110 °C. Derating curves in Figure 5 confirm usable ambient range depends on copper area and airflow.

Is DSRHD08-13 pin-compatible with other DSRHDx-13 variants?

Yes-DSRHD02-13 through DSRHD08-13 share identical T-MiniDIP package, pinout, and terminal assignments. Only V_RRM (200 V to 800 V) and related reverse leakage differ; forward characteristics and thermal parameters are consistent across the family.

Does DSRHD08-13 support lead-free reflow soldering?

Yes-its matte tin over copper lead frame is qualified for Pb-free reflow per J-STD-020 Level 1 moisture sensitivity and complies with IPC/JEDEC standards. Peak reflow temperature must not exceed 260 °C for ≤10 seconds, consistent with standard SnAgCu profiles.

Why is DSRHD08-13 marked as obsolete with no alternate part?

Diodes Incorporated discontinued the DSRHD08-13 per document DS35952 Rev. 5, citing end-of-life status and no designated replacement. No functional or pin-compatible successor has been released; design-in requires inventory planning and potential redesign to alternative bridge families like GBU8K or DB108S if long-term supply is critical.
