Diodes Incorporated RS2J-13

Overview

RS2J-13 from Diodes Incorporated is a 600 V, 1.5 A surface-mount fast recovery rectifier in SMA package, featuring 150 ns reverse recovery time, 1.3 V forward voltage at 1.5 A, and 50 A non-repetitive surge capability - used in AC/DC input stage of offline SMPS and auxiliary power supplies.

For engineers reviewing the RS2J-13 datasheet, RS2J-13 pinout, RS2J-13 application, or RS2J-13 equivalent, key selection criteria include peak reverse voltage rating, thermal resistance (20 K/W), junction-to-terminal thermal path, fast recovery performance under 60 Hz line-frequency switching, and UL 94V-0 molded plastic case compliance.

Technical Context

This device operates as a single-phase, half-wave rectifier with glass-passivated die construction, optimized for high-efficiency offline converters where low conduction loss and controlled reverse recovery are critical. It supports resistive or inductive loads at 60 Hz, with derating required for capacitive loads.

The 150 ns trr is measured under standardized conditions (IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A), and its 20 K/W junction-to-terminal thermal resistance assumes mounting on 5.0 mm² copper pads - enabling reliable operation up to 150 °C junction temperature.

Key Specifications

Pinout & Package

SMA package: molded plastic case with cathode band marking; two terminals - anode and cathode - mounted coplanar for reflow soldering. Weight ≈ 0.065 g. UL 94V-0 compliant.

Equivalent & Alternatives

The following parts are listed as comparable options for similar fast recovery rectifier applications.

Compared with STTH1L06S and MBR1560CT, RS2J-13 uniquely balances 600 V blocking, 1.5 A average current, SMA footprint, and 150 ns recovery - making it optimal for space-constrained, mains-input rectification where voltage rating and thermal integration are prioritized over ultra-low VF.

Availability

RS2J-13 is available at Aetrix Electronics and suitable for AC/DC adapters, industrial auxiliary power supplies, LED driver bulk rectification, and smart meter power conversion requiring stable component supply and long-term manufacturability.

Supply support for RS2J-13 includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Diodes Incorporated is a global manufacturer of discrete semiconductors and analog ICs, headquartered in Plano, Texas, serving automotive, industrial, computing, and consumer markets with high-reliability components.

The RS2x series targets cost-sensitive, high-volume power conversion applications demanding robust fast recovery performance in standard SMD packages - especially where thermal management via PCB layout is preferred over through-hole or heatsinked solutions.

FAQ

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

The absolute maximum junction temperature is +150 °C, verified per datasheet limits. Operation at this temperature requires strict adherence to derating curves - specifically, average current must be reduced to ≤0.75 A when terminal temperature reaches 120 °C, as shown in Figure 1 of DS15004 Rev. E-2.

Can RS2J-13 replace RS2M-13 in a 1000 V design?

No - RS2J-13 has a 600 V peak repetitive reverse voltage (VRRM), while RS2M-13 is rated for 1000 V. Substituting RS2J-13 in a 1000 V application risks catastrophic avalanche failure during line transients or peak AC cycles, as confirmed by the manufacturer's maximum ratings table.

Is RS2J-13 suitable for synchronous rectification topologies?

No - RS2J-13 is a passive silicon PN junction rectifier with fixed unidirectional conduction and 150 ns recovery. Synchronous rectification requires actively controlled MOSFETs with gate drive signals; this device lacks gate terminals or controllability and cannot be used in such circuits.

Does RS2J-13 meet lead-free and RoHS requirements?

Yes - RS2J-13 is manufactured with lead-free terminations and complies with EU RoHS Directive 2011/65/EU and China RoHS II. The "-13" suffix denotes tape-and-reel packaging with RoHS-compliant materials, and the device carries the Diodes Incorporated green product marking per their environmental compliance documentation.
