S5JBH Equivalent & Substitute Parts

Part Overview

The S5JBH is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 600 V DC reverse voltage and 5 A average rectified current in a surface mount DO-214AA (SMB) package. This component is classified as Active product status with AEC-Q101 automotive qualification and ROHS3 compliance. Substitute parts are identified based on matching or exceeding the electrical and mechanical specifications within the DO-214AA package form factor, enabling direct replacement in applications where the primary part is unavailable or where design requirements permit operation at lower current ratings with equivalent voltage ratings.

Substitute Part Grouping Explanation

Substitute parts for the S5JBH are grouped based on the following critical parameters that determine functional equivalence:

Voltage Rating: All substitute parts maintain the 600 V DC reverse voltage specification, ensuring compatibility with the primary application voltage environment.

Package Form Factor: All substitute parts use the DO-214AA (SMB) surface mount package, enabling direct mechanical and electrical board-level replacement.

Current Rating: Substitute parts are organized by average rectified current capacity. Parts rated at 5 A provide direct replacement capability. Parts rated below 5 A (1 A, 1.5 A, 2 A, 3 A) function as substitutes only in applications where the circuit design permits operation at the lower current rating.

Recovery Speed: The S5JBH operates at Standard Recovery (>500 ns). Substitute parts with Fast Recovery (≤500 ns) characteristics are electrically compatible and may be used interchangeably, as faster recovery represents an enhancement rather than a limitation.

Reverse Leakage Current: All substitute parts specify 5 µA @ 600 V, which is lower than the S5JBH specification of 10 µA @ 600 V, ensuring equivalent or superior leakage performance.

Compliance & Qualification: All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the primary part's environmental and regulatory status.

Engineering Selection Recommendations

Direct Replacement (5 A Rating): No substitute parts with 5 A current rating are provided in the substitute list. The S5JBH remains the only option for applications requiring the full 5 A average rectified current specification.

Reduced Current Applications (1 A to 3 A): The following substitute parts are suitable for applications where circuit design permits operation at reduced current ratings:

ER3JB-TP (3 A) provides the closest current match to the S5JBH while maintaining 600 V voltage rating and DO-214AA package compatibility. This part is Active status with ROHS3 compliance.

MURS360S-E3/52T and MURS360S-E3/5BT (1.5 A each) are suitable for applications requiring 1.5 A or less. Both are Active status with ROHS3 compliance and extended temperature range (-65°C to 175°C).

MURS160-E3/52T and MURS160-E3/5BT (2 A each) are suitable for applications requiring 2 A or less. Both are Active status with ROHS3 compliance and extended temperature range (-65°C to 175°C).

ER2J-LTP (2 A) is suitable for applications requiring 2 A or less. Active status with ROHS3 compliance and extended temperature range (-65°C to 175°C).

MURS260-E3/52T and MURS260-E3/5BT (2 A each) are suitable for applications requiring 2 A or less. Both are Active status with ROHS3 compliance and extended temperature range (-65°C to 175°C).

MURS160-13-F (1 A) is suitable for applications requiring 1 A or less. Active status with ROHS3 compliance.

RS2J-13-F (1.5 A) is suitable for applications requiring 1.5 A or less. Active status with ROHS3 compliance.

Packaging Considerations: All substitute parts use the DO-214AA (SMB) surface mount package, enabling direct board-level replacement without PCB redesign. Packaging variants (Tape & Reel vs. Cut Tape) do not affect electrical performance and are selected based on procurement and assembly requirements.

Compliance Status: All substitute parts maintain ROHS3 compliance, MSL 1 (Unlimited) moisture sensitivity rating, and REACH Unaffected status, matching the regulatory and environmental profile of the S5JBH.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part rated at 2 A in place of the S5JBH rated at 5 A?

A: No. The substitute part's 2 A current rating is the maximum average rectified current it can safely conduct. Using it in a circuit designed for 5 A operation will cause the device to exceed its rated current, resulting in thermal stress and potential failure. Substitute parts with lower current ratings are suitable only for applications where the actual circuit current demand does not exceed the substitute part's rating.

Q: Are all substitute parts compatible with the S5JBH's operating temperature range of -55°C to 150°C?

A: Most substitute parts have extended temperature ranges (-65°C to 175°C), which encompass the S5JBH range. However, some substitute parts (ER3JB-TP, RS2J-13-F) have upper temperature limits of 150°C, matching the S5JBH. All substitute parts operate within or exceed the S5JBH's specified temperature range.

Q: What is the difference between Standard Recovery and Fast Recovery diodes?

A: The S5JBH uses Standard Recovery (>500 ns reverse recovery time), while most substitute parts use Fast Recovery (≤500 ns). Fast Recovery diodes switch off more quickly, reducing switching losses and electromagnetic interference. Fast Recovery substitutes are electrically compatible with Standard Recovery applications and represent an enhancement in performance characteristics.

Q: Can I substitute MURS160-E3/5BT (Tape & Reel) with MURS160-E3/52T (Cut Tape)?

A: Yes. Both parts are electrically identical with the same part number base (MURS160), voltage rating (600 V), current rating (2 A), and package (DO-214AA). The packaging format (Tape & Reel vs. Cut Tape) affects procurement and assembly logistics but does not impact electrical performance or compatibility.

Q: Are all substitute parts AEC-Q101 qualified like the S5JBH?

A: The provided substitute part specifications do not include AEC-Q101 qualification data. If automotive-grade qualification is a design requirement, verify AEC-Q101 status with the substitute part manufacturer before selection.

Q: What is the significance of reverse leakage current differences between the S5JBH (10 µA) and substitute parts (5 µA)?

A: All substitute parts specify 5 µA reverse leakage current at 600 V, which is lower than the S5JBH's 10 µA specification. Lower reverse leakage current indicates superior blocking performance and reduced standby power dissipation. Substitute parts with lower leakage are electrically compatible and represent an improvement in this parameter.

Q: Can I use MURS260-E3/5BT as a direct replacement for S5JBH?

A: MURS260-E3/5BT is electrically compatible for applications where the circuit current demand does not exceed 2 A. The part maintains the 600 V voltage rating, DO-214AA package form factor, and ROHS3 compliance. However, it cannot replace the S5JBH in circuits requiring the full 5 A current capacity. Forward voltage drop is higher (1.45 V @ 2 A vs. 1.1 V @ 5 A), which may affect circuit performance in sensitive applications.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® formats. Tape & Reel packaging is standard for high-volume automated assembly. Cut Tape & Digi-Reel® packaging is suitable for lower-volume or mixed-component assembly. Both formats contain electrically identical components and are selected based on procurement volume and assembly equipment compatibility.
