Diodes Incorporated RS1J-13-F

Overview

RS1J-13-F from Diodes Incorporated is a surface-mount fast recovery rectifier diode with 600 V peak repetitive reverse voltage, 1.0 A average rectified output current, and 150 ns maximum reverse recovery time. It features glass passivated die construction, 30 A non-repetitive peak forward surge capability, and RoHS-compliant matte tin annealed terminals - used in AC/DC front-end rectification for switch-mode power supplies.

For engineers reviewing the RS1J-13-F datasheet, RS1J-13-F pinout, RS1J-13-F application, or RS1J-13-F equivalent, key selection criteria include its 600 V blocking rating, fast 150 ns t_RR, low 1.3 V forward voltage at 1.0 A, thermal resistance of 20 °C/W, and SMB package compatibility with automated assembly.

Technical Context

This device operates as a unidirectional silicon junction rectifier optimized for high-frequency switching applications. Its fast recovery time (150 ns) minimizes switching losses in SMPS and DC-DC converters, while the glass passivated die ensures stable performance under thermal cycling and humidity stress.

The SMB package provides enhanced thermal dissipation over SMA variants, supporting continuous 1.0 A conduction at terminal temperatures up to +120°C. Reverse leakage remains ≤5.0 µA at 25°C and ≤200 µA at 125°C under rated 600 V DC blocking conditions.

Key Specifications

FAQ

What is the cathode identification method for RS1J-13-F?

The cathode is marked by a distinct band printed on the body of the SMB package, aligned with the cathode terminal. This band is visible in top-view orientation and corresponds to the shorter leadframe tab in the package outline drawing. Polarity must be verified before PCB layout to prevent reverse-bias failure during operation.

Can RS1J-13-F replace RS1M-13-F in a 1000 V design?

No. RS1J-13-F has a 600 V V_RRM rating, while RS1M-13-F is rated for 1000 V. Substituting RS1J-13-F in a 1000 V application risks catastrophic avalanche breakdown under transient overvoltage. The devices share identical SMB packaging and thermal specs, but voltage rating is not interchangeable.

Is RS1J-13-F suitable for use in a synchronous rectifier circuit?

No - RS1J-13-F is a passive PN-junction rectifier, not a MOSFET-based synchronous rectifier. It cannot be actively controlled or gated. However, it serves as the freewheeling diode in non-synchronous flyback or forward converters where MOSFETs handle primary-side switching only.

What is the maximum PCB copper area recommended for thermal relief with RS1J-13-F?

Diodes Incorporated recommends a minimum 25 mm² of 1 oz copper connected to both anode and cathode pads for optimal thermal performance. The SMB footprint supports two thermal vias per pad (0.3 mm diameter, filled), reducing R_θJA to ~45 °C/W in standard 4-layer boards - critical for sustaining 1.0 A at +85°C ambient.
