RS3J General Purpose Rectifier Diode 600V 3A DO-214AB Equivalent & Substitute Parts

Part Overview

The RS3J is an active general purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 600V DC reverse voltage and 3A average rectified current in a surface mount DO-214AB (SMC) package. This component is designed for standard rectification applications requiring fast recovery characteristics with a reverse recovery time of 250 nanoseconds. The part is ROHS3 compliant and carries unlimited moisture sensitivity level (MSL 1), making it suitable for standard manufacturing environments. Equivalent and substitute parts are identified based on matching electrical specifications and mechanical compatibility within the DO-214AB package form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RS3J rectifier diode is determined by strict equivalence of the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 600V minimum
• Current - Average Rectified (Io): 3A minimum
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Reverse Recovery Time (trr): 250ns or faster
• Package / Case: DO-214AB, SMC (surface mount compatibility)
• Mounting Type: Surface Mount

Secondary Compatibility Factors:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1 (Unlimited)
• Operating Temperature Range: Minimum -55°C to 150°C junction temperature

All identified substitute parts meet or exceed these parameters within the DO-214AB package specification, ensuring direct functional and mechanical compatibility in surface mount applications.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed—RS3J, RS3J-13-F, MURS360T3G, and FR3J_R1_00001—are active products with ROHS3 compliance and MSL 1 rating, confirming their suitability for current manufacturing and assembly processes.

RS3J-13-F (Diodes Incorporated): Direct functional equivalent with identical voltage, current, and recovery time specifications. Extended operating temperature range (-65°C to 150°C) provides broader thermal margin compared to the base RS3J. Available in Tape & Reel packaging.

MURS360T3G (onsemi): Meets all primary substitution criteria with superior reverse recovery time of 75 nanoseconds, compared to 250 nanoseconds for the RS3J. Forward voltage is 1.25V at 3A, slightly lower than competing parts. Extended operating temperature range (-65°C to 175°C) supports high-temperature applications. Highest inventory availability at 105,100 pieces.

FR3J_R1_00001 (Panjit International Inc.): Functionally equivalent with identical voltage and current ratings. Reverse leakage current of 1 µA at 600V is superior to the RS3J specification of 10 µA. Capacitance specification provided at 60 pF @ 4V, 1MHz. Operating temperature range -50°C to 150°C. Available in Tape & Reel packaging.

Selection among these parts depends on application-specific requirements for reverse recovery time, forward voltage characteristics, and thermal operating range, all of which are met by the substitute parts within the DO-214AB package constraint.

Frequently Asked Questions (FAQ)

Q: Can RS3J-13-F be used as a direct replacement for RS3J in existing designs?

A: Yes. RS3J-13-F meets all critical electrical parameters: 600V reverse voltage, 3A average rectified current, 250ns reverse recovery time, and fast recovery speed classification. Both parts use the DO-214AB (SMC) surface mount package. The primary difference is packaging format (Tape & Reel versus Cut Tape & Digi-Reel) and extended operating temperature range of RS3J-13-F.

Q: What is the advantage of MURS360T3G over the RS3J?

A: MURS360T3G provides a reverse recovery time of 75 nanoseconds compared to RS3J's 250 nanoseconds, resulting in faster switching characteristics. This reduces switching losses in high-frequency rectification applications. Forward voltage is also lower at 1.25V versus unspecified for RS3J. Operating temperature range extends to 175°C, supporting higher thermal environments.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All parts use the DO-214AB (SMC) package specification, ensuring identical PCB footprint and land pattern compatibility. Surface mount assembly processes remain unchanged.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) & Digi-Reel packaging is suitable for manual handling and smaller volume applications. Tape & Reel (TR) packaging is optimized for automated pick-and-place assembly equipment and higher volume production. Both formats contain the same component in the DO-214AB package.

Q: Do all substitute parts meet RoHS and MSL requirements?

A: Yes. All four parts—RS3J, RS3J-13-F, MURS360T3G, and FR3J_R1_00001—are ROHS3 compliant and carry MSL 1 (Unlimited) rating, confirming compatibility with current manufacturing standards and unlimited shelf life under standard storage conditions.

Q: Which substitute part has the lowest reverse leakage current?

A: FR3J_R1_00001 specifies 1 µA reverse leakage current at 600V, compared to 10 µA for RS3J and MURS360T3G, and 5 µA for RS3J-13-F. Lower reverse leakage reduces standby current in applications where this parameter is critical.

Q: Can MURS360T3G be used in applications requiring 250ns reverse recovery time?

A: Yes. MURS360T3G's 75ns reverse recovery time is faster than the 250ns requirement, making it suitable for any application specifying 250ns or slower recovery. The faster recovery characteristic does not create incompatibility; it represents improved performance.
