Equivalent & Substitute Parts for RS2J-13 General Purpose Rectifier Diode

Part Overview

The RS2J-13 is a general purpose rectifier diode manufactured by Diodes Incorporated, rated for 600 V DC reverse voltage and 1.5 A average rectified current in a surface mount SMB (DO-214AA) package. This component is classified as discontinued at DiGi Electronics, which necessitates identification of equivalent and substitute parts for ongoing design support and procurement.

The RS2J-13 operates across a junction temperature range of -65°C to 150°C and features fast recovery characteristics with a reverse recovery time of 250 ns. Standard technology construction and RoHS non-compliance status are defining characteristics of this legacy component.

Substitute Part Grouping Explanation

Substitution of the RS2J-13 is determined by the following critical parameters:

Mandatory Matching Parameters:

Voltage - DC Reverse (Vr) (Max): 600 V
Package / Case: DO-214AA, SMB
Mounting Type: Surface Mount
Technology: Standard

Current Rating Considerations: Substitute parts are grouped by average rectified current (Io) rating. The RS2J-13 is rated at 1.5 A. Substitutes with equal or higher current ratings (1.5 A, 2 A, or 3 A) are electrically compatible for applications requiring 1.5 A or less. Substitutes with lower current ratings (1 A) are not suitable for the full 1.5 A specification.

Forward Voltage and Recovery Time: Forward voltage drop and reverse recovery time vary among substitutes. These parameters affect circuit performance but do not prevent substitution when the primary electrical requirements (voltage and current) are met.

Compliance and Product Status: The original RS2J-13 is RoHS non-compliant and discontinued. Active, RoHS3-compliant alternatives are available for new designs and ongoing procurement.

Engineering Selection Recommendations

Direct Parametric Equivalent:

RS2J-13-F (Diodes Incorporated) is the direct parametric equivalent to RS2J-13. This part maintains identical electrical specifications including 600 V reverse voltage, 1.5 A average rectified current, 1.3 V forward voltage at 1.5 A, and 250 ns reverse recovery time. RS2J-13-F is active in production and RoHS3 compliant, addressing the discontinued status and compliance limitations of the original part. This substitution requires no circuit redesign.

Cross-Manufacturer Equivalent:

RS2J-E3/5BT (Vishay General Semiconductor - Diodes Division) provides equivalent electrical performance with identical voltage, current, and recovery time specifications. This part is active and RoHS3 compliant. Capacitance at rated voltage is lower (17 pF versus 30 pF), which may benefit high-frequency applications. This substitution requires no circuit redesign.

Higher Current Rating Alternatives:

STTH2L06U, STTH2R06U, STTH3L06U, and STTH3R06U are suitable for applications where the 1.5 A requirement can be met by higher-rated devices. These parts maintain 600 V reverse voltage and DO-214AA packaging. All are active and RoHS3 compliant. Selection among these depends on forward voltage and recovery time requirements specific to the application.

Lower Current Rating Alternatives:

STTH1L06U and STTH1R06U are rated at 1 A average rectified current. These parts are not suitable for applications requiring the full 1.5 A specification of the RS2J-13. Use is limited to circuits where maximum current demand does not exceed 1 A.

Compliance Considerations:

All recommended substitutes are RoHS3 compliant and active in production, eliminating procurement and regulatory compliance issues associated with the discontinued, non-compliant RS2J-13.

Frequently Asked Questions (FAQ)

Q: Can RS2J-13-F be used as a direct replacement for RS2J-13?

A: Yes. RS2J-13-F is the direct parametric equivalent, maintaining all critical electrical specifications: 600 V reverse voltage, 1.5 A average rectified current, 1.3 V forward voltage at 1.5 A, and 250 ns reverse recovery time. Both use DO-214AA (SMB) surface mount packaging. No circuit modifications are required.

Q: What is the difference between RS2J-E3/5BT and RS2J-13-F?

A: Both parts are parametric equivalents with identical voltage, current, and recovery time ratings. RS2J-E3/5BT is manufactured by Vishay, while RS2J-13-F is manufactured by Diodes Incorporated. RS2J-E3/5BT has lower capacitance (17 pF versus 30 pF at 4 V, 1 MHz), which may provide performance advantages in high-frequency switching applications. Both are RoHS3 compliant and active.

Q: Can STTH1L06U or STTH1R06U replace RS2J-13?

A: No. STTH1L06U and STTH1R06U are rated at 1 A average rectified current, which is below the 1.5 A specification of RS2J-13. These parts are suitable only for applications where maximum current demand does not exceed 1 A.

Q: Are STTH2 and STTH3 series parts suitable replacements?

A: Yes, for applications where 1.5 A or less is required. STTH2L06U, STTH2R06U, STTH3L06U, and STTH3R06U are rated at 2 A and 3 A respectively, both exceeding the 1.5 A requirement. All maintain 600 V reverse voltage and DO-214AA packaging. Forward voltage and recovery time differ among variants; selection depends on circuit performance requirements. All are RoHS3 compliant and active.

Q: What is the significance of the "L" and "R" designations in STMicroelectronics part numbers?

A: The "L" and "R" designations indicate different forward voltage and reverse recovery time characteristics within the same current rating. "L" variants typically feature lower forward voltage (1.3 V) with longer recovery time (80-85 ns). "R" variants feature higher forward voltage (1.7 V) with shorter recovery time (35-50 ns). Selection depends on whether the application prioritizes lower conduction losses or faster switching performance.

Q: Is the DO-214AA package identical across all substitute parts?

A: Yes. All substitute parts listed use the DO-214AA (SMB) surface mount package, ensuring mechanical and electrical compatibility with existing PCB layouts designed for RS2J-13.

Q: What is the impact of different reverse recovery times on circuit performance?

A: Reverse recovery time (trr) affects switching speed and electromagnetic interference characteristics. RS2J-13 and its direct equivalents have 250 ns recovery time. STMicroelectronics alternatives have shorter recovery times (35-85 ns), which reduce switching losses and EMI in high-frequency applications. Longer recovery times (250 ns) are suitable for lower-frequency rectification circuits.

Q: Are all substitute parts RoHS3 compliant?

A: All recommended substitute parts are RoHS3 compliant. The original RS2J-13 is RoHS non-compliant. Compliance with RoHS3 is a key advantage of all listed alternatives for new designs and procurement in regulated markets.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) packaging formats. All maintain the DO-214AA (SMB) component package for PCB compatibility. Packaging format selection depends on assembly process requirements and order quantities.
