RS3JHE3_A/I Equivalent & Substitute Parts

Part Overview

The RS3JHE3_A/I is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount diode operates at 600 V DC reverse voltage with a 3 A average rectified current rating and is packaged in the DO-214AB (SMC) form factor. The device is classified as Active product status with AEC-Q101 automotive qualification and ROHS3 compliance.

Substitute parts are necessary when the primary part number becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when sourcing from multiple suppliers is required for supply chain continuity. The RS3JHE3_A/I can be replaced with equivalent or alternative rectifier diodes that meet the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the RS3JHE3_A/I is determined by the following critical parameters:

Electrical Specifications:

Voltage - DC Reverse (Vr) (Max): 600 V
Current - Average Rectified (Io): 3 A
Package / Case: DO-214AB, SMC
Mounting Type: Surface Mount

Performance Characteristics:

Speed classification: Fast Recovery ≤ 500ns, > 200mA (Io)
Reverse Recovery Time (trr): 250 ns
Current - Reverse Leakage @ Vr: 10 µA @ 600 V

Compliance & Environmental:

RoHS Status: ROHS3 Compliant

Substitute parts are grouped into three categories:

Parametric Equivalents (Vishay RS3J Series): Parts with identical electrical specifications, reverse recovery time, and automotive qualification. These differ only in packaging format (Tape & Reel vs. Cut Tape).

Manufacturer Recommended Alternatives (Cross-Manufacturer): Parts from alternative manufacturers (Micro Commercial Co, Good-Ark Semiconductor, onsemi) that meet the 600 V / 3 A electrical requirements and DO-214AB package specification. These may have variations in forward voltage, reverse recovery time, or operating temperature range.

Discontinued Parts: Parts that are no longer actively produced but remain available in inventory and meet all electrical and mechanical specifications.

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications):

The RS3J-E3/57T, RS3J-E3/9AT, and RS3JHE3_A/H are parametric equivalents of the RS3JHE3_A/I. All three parts share identical electrical characteristics (600 V, 3 A, 250 ns reverse recovery time, 1.3 V forward voltage at 2.5 A). Selection among these three is determined by packaging format requirements:

RS3J-E3/57T: Cut Tape format for applications requiring individual component handling
RS3J-E3/9AT and RS3JHE3_A/H: Tape & Reel format for automated assembly processes

All three maintain ROHS3 compliance, MSL 1 rating, and -55°C to 150°C operating temperature range. The RS3JHE3_A/H retains AEC-Q101 automotive qualification identical to the primary part.

For Cross-Manufacturer Substitution:

Alternative manufacturers provide functionally equivalent 600 V / 3 A rectifier diodes in DO-214AB packaging:

MURS360T3G (onsemi): Offers superior forward voltage performance (1.25 V @ 3 A) and extended operating temperature range (-65°C to 175°C). Reverse recovery time of 75 ns is longer than the primary part.
ES3J (Good-Ark Semiconductor): Provides fast recovery characteristics (35 ns reverse recovery time) with 1.7 V forward voltage at 3 A. Maintains -55°C to 150°C operating range and ROHS3 compliance.
ER3J-TP (Micro Commercial Co): Fast recovery diode (35 ns reverse recovery time) with 1.7 V forward voltage. Extended operating temperature range (-50°C to 175°C).
S3J-TP (Micro Commercial Co): Standard recovery diode (>500 ns) with lowest forward voltage (1.2 V @ 3 A). Maintains -55°C to 150°C operating range.

For Discontinued Part Replacement:

RS3J V7G (Taiwan Semiconductor Corporation) is discontinued at DiGi Electronics but remains available in inventory. This part is a parametric equivalent with identical 250 ns reverse recovery time and 1.3 V forward voltage characteristics. Use only when existing inventory must be depleted or when historical traceability is required.

Compliance Considerations:

All active substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating. Parts selected for automotive applications must verify AEC-Q101 qualification status independently. The RS3JHE3_A/H explicitly retains automotive qualification; other substitutes should be evaluated against specific automotive requirements.

Frequently Asked Questions (FAQ)

Q: Can RS3J-E3/57T replace RS3JHE3_A/I in production assembly?

A: Yes. RS3J-E3/57T is a parametric equivalent with identical electrical specifications. The primary difference is packaging format: Cut Tape (CT) versus Tape & Reel (TR). Cut Tape format requires manual component placement or specialized handling equipment. Verify that your assembly process supports Cut Tape format before substitution.

Q: What is the difference between the Vishay RS3J series substitutes?

A: RS3J-E3/57T, RS3J-E3/9AT, and RS3JHE3_A/H are electrically identical. Differences are limited to packaging format (Cut Tape vs. Tape & Reel) and supplier tape specifications. All three maintain identical performance characteristics: 600 V reverse voltage, 3 A current rating, 250 ns reverse recovery time, and 1.3 V forward voltage at 2.5 A.

Q: Can I use MURS360T3G as a direct replacement for RS3JHE3_A/I?

A: MURS360T3G meets the 600 V / 3 A electrical requirements and uses the same DO-214AB package. However, it differs in forward voltage (1.25 V @ 3 A versus 1.3 V @ 2.5 A) and reverse recovery time (75 ns versus 250 ns). These differences may affect circuit performance in applications sensitive to switching speed or power dissipation. Verify circuit compatibility before substitution.

Q: What is the significance of reverse recovery time differences?

A: Reverse recovery time (trr) determines how quickly the diode transitions from conducting to blocking state. The RS3JHE3_A/I has 250 ns recovery time. Substitutes with shorter recovery times (ER3J-TP and ES3J at 35 ns, MURS360T3G at 75 ns) switch faster and generate less reverse current. Substitutes with longer recovery times may increase switching losses. Circuit design must accommodate these differences.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating. All parts are suitable for lead-free soldering processes.

Q: Can I use S3J-TP as a substitute if my circuit requires fast recovery characteristics?

A: No. S3J-TP is classified as Standard Recovery (>500 ns), which is slower than the RS3JHE3_A/I (Fast Recovery ≤ 500 ns, 250 ns typical). For applications requiring fast recovery performance, use ER3J-TP, ES3J, or MURS360T3G instead.

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

A: Tape & Reel (TR) format supplies components on continuous tape wound on reels, suitable for automated pick-and-place assembly. Cut Tape (CT) format supplies components on tape segments, typically 5 or 10 components per strip, requiring manual placement or specialized handling. Manufacturing process requirements determine which format is appropriate.

Q: Is RS3J V7G still available for new designs?

A: RS3J V7G is discontinued at DiGi Electronics and should not be specified for new designs. Use active alternatives such as RS3J-E3/9AT, RS3JHE3_A/H, or cross-manufacturer equivalents instead. Existing inventory of RS3J V7G may be available through alternative distributors for legacy product support only.

Q: Do all substitutes support automotive applications?

A: Only RS3JHE3_A/H explicitly carries AEC-Q101 automotive qualification. Other substitutes do not list automotive qualification in their specifications. For automotive applications, verify AEC-Q101 status with the manufacturer or use RS3JHE3_A/H as the qualified substitute.

Q: What forward voltage should I use for circuit calculations?

A: Use the forward voltage specification at the operating current of your circuit. RS3JHE3_A/I is specified at 1.3 V @ 2.5 A. Cross-manufacturer substitutes may have different test conditions (typically 1.7 V @ 3 A or 1.25 V @ 3 A). Verify the forward voltage at your actual operating current before finalizing circuit calculations.
