Diodes Incorporated DSRHD02-13

Overview

DSRHD02-13 from Diodes Incorporated is a glass passivated single-phase bridge rectifier in T-MiniDIP package, rated for 200 V peak repetitive reverse voltage, 1.0 A average output current, and 150°C junction temperature-used in AC/DC power supplies for industrial control modules requiring compact, high-temperature-stable rectification.

For engineers reviewing the DSRHD02-13 datasheet, DSRHD02-13 pinout, DSRHD02-13 application, or DSRHD02-13 equivalent, key selection criteria include its 1.1 V forward voltage at 1.0 A, 30 A non-repetitive surge rating, thermal resistance of 25°C/W (junction-to-lead), RoHS-compliant matte tin finish, and T-MiniDIP mechanical compatibility with space-constrained PCB layouts.

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 ambient range and supports resistive/inductive loads at 60 Hz, with 20% current derating required for capacitive loads.

Thermal performance is defined by R_θJL = 25°C/W and R_θJA = 62.5°C/W on aluminum substrate, allowing reliable operation under sustained 1.0 A load when properly heatsinked. Reverse leakage remains ≤10 µA at 25°C and ≤150 µA at 125°C under rated blocking voltage.

FAQ

What is the pin configuration of DSRHD02-13?

The DSRHD02-13 uses a standard 4-pin T-MiniDIP layout: pins 1 and 4 are AC inputs (~), pin 2 is positive DC output (+), and pin 3 is negative DC output (–). Polarity is confirmed by the top-view marking "_ + ~ ~" and bottom-view terminal mapping in DS35952 Rev. 5.

Is DSRHD02-13 still in production?

No-DSRHD02-13 is officially obsolete and discontinued per Diodes Incorporated's DS35952 Rev. 5 document (July 2018), with no alternate part offered. Aetrix Electronics maintains limited legacy stock for design continuity and repair programs.

Can DSRHD02-13 replace DSRHD04-13 in a 200 V design?

Yes-DSRHD02-13 is rated for 200 V VRRM and matches DSRHD04-13's 400 V rating only in voltage headroom, but its lower blocking voltage makes it unsuitable as a drop-in replacement in 400 V circuits. In 200 V designs, both share identical package, thermal, and current specs.

What is the recommended pad layout for DSRHD02-13?

Diodes Incorporated specifies a T-MiniDIP pad layout with 3.9 mm pin pitch, 0.65 mm pad width, and 1.2 mm pad length. Recommended copper pour on the PCB underside improves thermal dissipation; exact dimensions are published in Diodes' package outline document P021AA (accessible via diodes.com/package-outlines.html).
