Diodes Incorporated RH06-T

Overview

RH06-T from Diodes Incorporated is a 0.5A surface-mount standard recovery bridge rectifier with 600V peak repetitive reverse voltage, 1.15V max forward voltage at 0.4A, and 30A non-repetitive surge rating-designed for AC/DC conversion in compact power supplies for industrial control and consumer adapters.

For engineers reviewing the RH06-T datasheet, RH06-T pinout, RH06-T application, or RH06-T equivalent, key selection criteria include its MiniDIP package footprint, 150°C max junction temperature, 150ns reverse recovery time (per element), and RoHS-compliant lead-free finish suitable for automated SMT assembly.

Technical Context

This single-phase, full-wave bridge rectifier integrates four silicon diodes in a monolithic configuration to convert AC input to pulsating DC output. It operates with 60Hz resistive or inductive loads and requires 20% current derating for capacitive loads.

Thermal performance is defined by 85°C/W junction-to-ambient thermal resistance when mounted on a PCB. Reverse recovery time is measured under standardized conditions: IF = 0.5A, IR = 1.0A, Irr = 0.25A.

Key Specifications

Pinout & Package

FAQ

What is the maximum allowable PCB trace width for RH06-T's AC input pads?

The recommended pad layout specifies X = 1.65 mm and Y = 1.80 mm for each terminal. For 0.5A continuous current, IPC-2221 guidelines suggest ≥0.3 mm trace width on external layers with 1 oz copper. Internal layer traces should be ≥0.4 mm to maintain temperature rise below 20°C under worst-case ambient conditions.

Does RH06-T require heatsinking in typical 0.5A applications?

No dedicated heatsink is required. With RθJA = 85°C/W and 0.5A × 1.15V ≈ 0.575W dissipation, junction temperature rise is ~49°C above ambient. At TA = +40°C, TJ ≈ 89°C-well within the –55°C to +150°C rating. Adequate copper pour around terminals improves thermal performance.

Can RH06-T replace RH04-T in an existing design?

Yes, RH06-T is a direct upgrade: identical MiniDIP package, pinout, and thermal characteristics, but with higher 600V VRRM versus RH04-T's 400V. No layout or firmware changes are needed; it provides increased voltage margin for designs targeting global mains input or transient-prone environments.

Is RH06-T qualified for automotive applications per AEC-Q101?

No-RH06-T is not AEC-Q101 qualified. Diodes states that automotive-grade variants require specific change control, PPAP capability, and IATF 16949 manufacturing; RH06-T is intended for industrial and commercial use. For automotive, contact Diodes for qualified alternatives like the ABS210Q or GBU6JL.
