Diodes Incorporated RS3D-13

Overview

RS3D-13 from Diodes Incorporated is a 200 V, 3.0 A surface-mount fast recovery rectifier in SMB package, featuring 150 ns reverse recovery time, 1.3 V forward voltage at 3.0 A, and 100 A non-repetitive surge capability - deployed in AC/DC front-end rectification for industrial power supplies.

For engineers reviewing the RS3D-13 datasheet, RS3D-13 pinout, RS3D-13 application, or RS3D-13 equivalent, key selection criteria include peak repetitive reverse voltage (200 V), average rectified current (3.0 A @ TT = 75°C), thermal resistance (25 K/W), fast recovery performance (150 ns), and SMB package compatibility with automated assembly.

Technical Context

This device is a single-phase, silicon planar fast recovery rectifier with glass-passivated die construction. It delivers low forward voltage drop (1.3 V @ 3.0 A) and high surge robustness (100 A, 8.3 ms half-sine), optimized for switching power supply input stages where efficiency and thermal management are critical.

Reverse recovery is characterized under defined conditions: IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A. Junction capacitance is 50 pF at 1.0 MHz and 4.0 V reverse bias, supporting stable high-frequency operation without excessive ringing in flyback or boost converters.

FAQ

What is the maximum junction temperature for RS3D-13?

The RS3D-13 has an operating junction temperature range of –65°C to +150°C. Its thermal resistance (RJT = 25 K/W) is measured with a 5.0 mm² copper pad acting as a heatsink. Derating begins above 75°C terminal temperature, per Figure 1 in the datasheet, where average forward current drops linearly to zero at 150°C.

Can RS3D-13 be used in full-bridge configurations?

Yes - RS3D-13 is a single-diode device rated for 200 V reverse voltage and 3.0 A average forward current, making it suitable for each leg of a discrete full-bridge rectifier. Four units can be assembled into a standard bridge; ensure matched VFM and trr across devices for balanced thermal stress and reduced EMI.

Is RS3D-13 compliant with lead-free reflow profiles?

Yes - RS3D-13 features solderable terminals qualified per MIL-STD-202, Method 208, and is compatible with standard lead-free reflow profiles (peak temperature up to 260°C). The SMB package's thermal mass and UL 94V-0 molding compound support reliable joint formation without delamination or voiding.

How does capacitive loading affect RS3D-13 current rating?

For capacitive loads, the average rectified output current must be derated by 20% from the rated 3.0 A. This accounts for increased peak current stress during capacitor charging, which elevates junction temperature and accelerates wear-out. Use Figure 1's derating curve with adjusted IO = 2.4 A as the effective continuous rating under heavy capacitive loading.
