Diodes Incorporated RS1J-13

Overview

RS1J-13 from Diodes Incorporated is a surface-mount fast recovery rectifier diode rated for 600 V peak repetitive reverse voltage, 1.0 A average forward current, and 150 ns reverse recovery time, with 1.3 V forward voltage drop at 1.0 A. It features glass-passivated die construction, RoHS-compliant matte tin terminals, and is optimized for high-frequency switching power supplies and AC/DC adapters.

For engineers reviewing the RS1J-13 datasheet, RS1J-13 pinout, RS1J-13 application, or RS1J-13 equivalent, key selection criteria include its 600 V blocking capability, fast 150 ns t_RR, low 1.3 V V_F at rated current, thermal resistance of 20 °C/W, and SMB package suitability for automated SMT assembly in compact power converters.

Technical Context

This discrete fast recovery rectifier operates as a unidirectional current switch in bridge or single-phase rectification stages, where rapid turn-off minimizes switching losses during high-frequency operation (e.g., >50 kHz). Its 150 ns reverse recovery time and 15 pF junction capacitance are measured under standardized conditions (I_F = 0.5 A, I_R = 1.0 A, I_RR = 0.25 A).

The device supports continuous conduction up to +120 °C terminal temperature with 1.0 A average output current, derated linearly above that point. Its surge rating of 30 A (8.3 ms half-sine) enables robust handling of line transients and inrush events in offline SMPS front-end designs.

Key Specifications

Pinout & Package

RS1J-13 is housed in an SMB (DO-214AA) plastic surface-mount package with cathode band polarity marking. The two-terminal device has no internal connections beyond anode and cathode; mounting orientation follows standard SMB footprint with cathode band aligned per PCB silkscreen.

FAQ

What is the maximum operating temperature for RS1J-13?

The RS1J-13 has an operating junction temperature range of –65 °C to +150 °C. Its average forward current rating is specified at +120 °C terminal temperature, with linear derating to zero at +150 °C. Thermal design must ensure terminal temperature remains ≤+120 °C under full load to maintain 1.0 A output capability.

Is RS1J-13 suitable for synchronous rectification circuits?

No - RS1J-13 is a passive silicon PN-junction fast recovery diode, not a MOSFET-based synchronous rectifier. It lacks gate control and cannot be actively switched. It functions only as a unidirectional conduction device, making it appropriate for conventional diode rectification but incompatible with gate-driven synchronous topologies.

Does RS1J-13 require moisture preconditioning before reflow?

No - RS1J-13 is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30 °C/60% RH and placed directly into reflow without baking. This eliminates pre-reflow bake steps and reduces manufacturing cycle time and cost.

How does RS1J-13 differ from RS1JB-13-F?

RS1J-13 and RS1JB-13-F are identical electrically and physically. The "B" suffix and "-F" suffix denote packaging and marking variants: RS1J-13 uses SMA packaging (5000/reel), while RS1JB-13-F uses SMB packaging (3000/reel) and includes halogen/antimony-free "Green" compliance marking. Both share identical electrical specs and SMB outline applies to RS1J-13 per Diodes' ordering note clarification.
