S3JBHR5G Equivalent & Substitute Parts

Part Overview

The S3JBHR5G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 600 V DC reverse voltage and 3 A average rectified current in a surface mount DO-214AA (SMB) package. This part is discontinued at DiGi Electronics, necessitating identification of equivalent and substitute components for ongoing design support and procurement requirements. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts provide functional alternatives with acceptable parameter variations for the intended application.

Substitute Part Grouping Explanation

Substitute parts for the S3JBHR5G are classified into two categories based on electrical parameter alignment:

Parametric Equivalents maintain all critical electrical specifications: 600 V reverse voltage rating, 3 A average rectified current, standard recovery speed (>500 ns), DO-214AA SMB package, and -55°C to 150°C operating temperature range. These parts differ only in manufacturer, product status, or packaging format (Tape & Reel versus Cut Tape).

Similar Parts share the 600 V reverse voltage rating and DO-214AA SMB package but vary in average rectified current (1 A to 2 A), forward voltage characteristics, recovery speed classification, or operating temperature range. These parts are suitable for applications where the full 3 A current rating is not required or where enhanced recovery speed characteristics are beneficial.

The following parameters determine substitution eligibility:

Voltage - DC Reverse (Vr) (Max): Must equal 600 V
Package / Case: Must be DO-214AA, SMB (or compatible SMA variant for package-flexible designs)
Operating Temperature Range: Must encompass or exceed -55°C to 150°C
Current - Average Rectified (Io): 3 A for parametric equivalents; 1 A to 2 A acceptable for similar parts
Technology: Standard recovery classification for parametric equivalents

Engineering Selection Recommendations

Primary Recommendation: S3JBH

The S3JBH is the direct parametric equivalent to the S3JBHR5G. Manufactured by Taiwan Semiconductor Corporation, it maintains identical electrical specifications including 600 V reverse voltage, 3 A average rectified current, 1.15 V forward voltage at 3 A, and 1.5 µs reverse recovery time. The S3JBH is currently active in production and available in Tape & Reel packaging. This part is the preferred replacement for direct substitution without design modification.

Secondary Recommendation: S3JB

The S3JB, manufactured by HY Electronic (Cayman) Limited, provides parametric equivalence with improved reverse leakage characteristics (5 µA versus 10 µA at 600 V) and slightly lower forward voltage (1.1 V versus 1.15 V at 3 A). This part is AEC-Q101 qualified and actively produced. The S3JB is suitable for applications requiring automotive-grade reliability or where reduced leakage current is beneficial.

Tertiary Recommendation: S3JA_R1_00001

The S3JA_R1_00001, manufactured by Panjit International Inc., maintains the 600 V and 3 A specifications with superior reverse leakage performance (1 µA at 600 V). This part is actively produced and suitable for applications where minimal leakage current is critical.

Current-Reduced Alternatives

For applications where the full 3 A rating is not required, the following parts provide 600 V rated alternatives with reduced current ratings:

S2J-LTP (2 A, Micro Commercial Co, active)
S2J-13-F (1.5 A, Diodes Incorporated, active)
RS2J-13-F (1.5 A, Diodes Incorporated, active, fast recovery)
MURS160-13-F (1 A, Diodes Incorporated, active, fast recovery)

These parts are suitable only for circuits designed to operate at their respective current ratings and should not be used as direct replacements in 3 A applications.

Frequently Asked Questions (FAQ)

Q: Can S3JBH be used as a direct replacement for S3JBHR5G?

A: Yes. The S3JBH is a parametric equivalent with identical voltage rating (600 V), current rating (3 A), forward voltage (1.15 V @ 3 A), reverse recovery time (1.5 µs), and package (DO-214AA SMB). The S3JBH is currently in active production, making it the recommended replacement for the discontinued S3JBHR5G.

Q: What is the difference between S3JB and S3JBH?

A: Both parts maintain 600 V and 3 A specifications. The S3JBH is manufactured by Taiwan Semiconductor Corporation with 10 µA reverse leakage at 600 V. The S3JB is manufactured by HY Electronic with 5 µA reverse leakage and 1.1 V forward voltage. The S3JB carries AEC-Q101 automotive qualification. Selection depends on leakage current requirements and automotive compliance needs.

Q: Can lower-current parts like S2J-13-F or MURS160-13-F replace the S3JBHR5G?

A: No. These parts are rated for 1.5 A and 1 A respectively, below the 3 A requirement of the S3JBHR5G. Using undersized components in 3 A applications results in excessive junction temperature, reduced reliability, and potential component failure. These parts are suitable only for circuits designed for their respective current ratings.

Q: Does package format affect substitution eligibility?

A: The S3JBHR5G uses DO-214AA (SMB) package. All recommended parametric equivalents use the same package. Parts with SMA package (DO-214AC) such as RS2JA-13-F or S2JA-13-F are not direct substitutes due to different footprint and lead configuration, though they may be considered for package-flexible designs with PCB layout modification.

Q: What is the significance of reverse recovery time (trr)?

A: Reverse recovery time affects switching speed and electromagnetic interference characteristics. The S3JBHR5G has 1.5 µs recovery time (standard recovery classification). Parametric equivalents S3JBH and S3JB maintain this specification. Parts like MURS160-13-F with 50 ns recovery time are fast-recovery devices suitable for high-frequency applications but not direct replacements for standard-recovery designs.

Q: Are all recommended parts RoHS3 compliant?

A: Yes. All parametric equivalents and similar parts listed maintain ROHS3 compliance, consistent with the S3JBHR5G specification.

Q: What is the operating temperature range consideration?

A: The S3JBHR5G operates from -55°C to 150°C junction temperature. All parametric equivalents maintain this range. Some similar parts extend to -65°C or 175°C, providing wider operating margins for temperature-sensitive applications.
