Diodes Incorporated RS2J-13-F

Overview

RS2J-13-F from Diodes Incorporated is a surface-mount fast recovery rectifier diode rated for 600 V peak repetitive reverse voltage, 1.5 A average rectified output current at 120°C terminal temperature, and 50 A non-repetitive surge current. It features 150 ns reverse recovery time, 1.3 V forward voltage at 1.5 A, and is packaged in SMB with glass passivated die construction for high-efficiency AC/DC front-end and flyback snubber circuits.

For engineers reviewing the RS2J-13-F datasheet, RS2J-13-F pinout, RS2J-13-F application, or RS2J-13-F equivalent, key selection criteria include its 600 V blocking capability, fast 150 ns trr, low 1.3 V VF at rated current, RoHS-compliant lead-free matte tin plating, and SMB package thermal resistance of 20°C/W - all critical for compact, thermally constrained power supply designs.

Technical Context

This device operates as a unidirectional switching diode in single-phase rectification topologies. Its 150 ns reverse recovery time enables efficient operation in 50–100 kHz SMPS designs, while the 600 V VRRM rating supports universal-input (85–265 VAC) offline converters and PFC boost stages.

The SMB package provides 20°C/W junction-to-terminal thermal resistance when mounted on 5.0 mm² copper pads, and the glass-passivated junction ensures stable leakage performance - IRM ≤ 5.0 µA at 25°C and ≤ 200 µA at 125°C under rated DC blocking voltage.

Key Specifications

Pinout & Package

FAQ

What is the maximum junction temperature for RS2J-13-F?

The absolute maximum junction temperature is +150°C, with derated average current beginning at terminal temperatures above 120°C per Figure 1 in DS15004. At 150°C TJ, IO drops to approximately 0.9 A due to thermal resistance limitations and silicon characteristics.

Is RS2J-13-F qualified for automotive applications?

RS2J-13-F is not AEC-Q101 qualified out-of-the-box. Diodes offers automotive-grade variants (e.g., RS2J-13-F-A) with PPAP documentation, IATF 16949 manufacturing, and extended qualification testing - contact Diodes or Aetrix for automotive-specific part numbers and change control support.

Can RS2J-13-F replace a standard recovery rectifier like 1N4007?

No - RS2J-13-F is a fast recovery device (150 ns trr) optimized for switching power supplies, whereas 1N4007 is a general-purpose rectifier with ~30 µs recovery. Substitution would cause excessive switching loss, overheating, and EMI in high-frequency circuits; it is only acceptable in low-frequency (<1 kHz), low-efficiency linear supplies.

What is the recommended PCB pad layout for RS2J-13-F in SMB package?

Per Diodes' DS15004 page 5, use 4.30 mm C, 1.80 mm G, 2.50 mm X, 6.80 mm X1, and 2.30 mm Y dimensions (all in mm). Maintain ≥5.0 mm² copper area per terminal for thermal relief, and ensure solder mask defined pads to prevent bridging during reflow.
