• Type: Zener
• Mounting Type: Through Hole
• Package / Case: P600 or compatible axial configuration
• Operating Temperature Range: -55°C to 175°C (TJ)
• RoHS Status: ROHS3 Compliant

Secondary Compatibility Parameters:

• Voltage - Breakdown (Min): 167V or higher
• Voltage - Clamping (Max) @ Ipp: Within application tolerance
• Current - Peak Pulse (10/1000µs): Minimum 18.7A
• Power - Peak Pulse: Minimum 5000W

All identified substitute parts meet the primary matching criteria.

Parameter Comparison

Engineering Selection Recommendations

5KP150CA and 5KP150CA-B (Littelfuse Inc.)

These parts are direct functional equivalents to the 5KP150CE3/TR13. Both maintain identical reverse standoff voltage (150V), breakdown voltage (167V minimum), and peak pulse power rating (5000W). The clamping voltage of 243V and peak pulse current of 21A are within the operational envelope of the original component. Both variants are ROHS3 compliant with unlimited MSL rating. The primary distinction is packaging: 5KP150CA is supplied in Cut Tape format, while 5KP150CA-B is supplied in Bulk. Selection between these variants depends on procurement and assembly requirements.

15KPA150CA (MDE Semiconductor Inc)

This part maintains the 150V reverse standoff voltage and is ROHS3 compliant with unlimited MSL rating. The 15KPA150CA offers enhanced performance characteristics with 62.4A peak pulse current and 15000W peak pulse power dissipation, representing a higher-rated variant within the 150V class. The clamping voltage of 241.9V is lower than the original component, providing improved transient suppression. This part is suitable for applications requiring higher current handling capacity. Packaging is supplied in Bulk format.

BZW50-150B (STMicroelectronics)

This part is a 150V standoff voltage equivalent from the TRANSIL™ series. It maintains ROHS3 compliance and unlimited MSL rating. The BZW50-150B features a higher clamping voltage of 343V and significantly higher peak pulse current of 175A (measured at 8/20µs pulse width). The package configuration is R-6 axial, which differs from the P600 package of the original component. Physical dimensions and PCB footprint compatibility must be verified before selection. This part is suitable for high-current transient suppression applications.

Selection Basis:

All substitute parts are Active products with ROHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory alignment with the original component. Selection should be based on specific application requirements regarding clamping voltage performance, peak pulse current capacity, and physical package compatibility. The Littelfuse 5KP150CA variants provide the closest electrical and mechanical match to the original 5KP150CE3/TR13.

Frequently Asked Questions (FAQ)

Q: Can the 5KP150CA be used as a direct replacement for the 5KP150CE3/TR13?

A: Yes. Both parts share identical reverse standoff voltage (150V), breakdown voltage (167V minimum), and peak pulse power rating (5000W). The clamping voltage of 243V and peak pulse current of 21A are functionally compatible. Both are ROHS3 compliant with unlimited MSL rating and Through Hole P600 axial mounting. The primary difference is packaging format (Cut Tape versus Tape & Reel).

Q: What is the difference between 5KP150CA and 5KP150CA-B?

A: These parts are electrically identical. The distinction is packaging: 5KP150CA is supplied in Cut Tape (CT) format, while 5KP150CA-B is supplied in Bulk format. Both maintain the same electrical specifications, compliance certifications, and mounting configuration. Selection depends on procurement and assembly line requirements.

Q: Is the 15KPA150CA a suitable substitute?

A: Yes, the 15KPA150CA is a suitable substitute for applications requiring higher current handling. It maintains the 150V reverse standoff voltage and ROHS3 compliance. The 15KPA150CA provides 62.4A peak pulse current and 15000W peak pulse power dissipation, compared to 18.7A and 5000W for the original part. The lower clamping voltage of 241.9V provides improved transient suppression. This part is appropriate for high-current transient protection circuits.

Q: Can the BZW50-150B replace the 5KP150CE3/TR13?

A: The BZW50-150B is electrically compatible as a 150V standoff voltage TVS diode with ROHS3 compliance. However, the package configuration differs: BZW50-150B uses R-6 axial package, while the original uses P600 axial package. Physical dimensions and PCB footprint compatibility must be verified. The BZW50-150B features higher peak pulse current (175A) and higher clamping voltage (343V), making it suitable for high-current applications where package compatibility can be accommodated.

Q: What are the critical parameters for TVS diode substitution?

A: Critical parameters include reverse standoff voltage (150V for this application), bidirectional channel configuration (1 channel), zener type, Through Hole mounting, and axial package format. Secondary parameters include breakdown voltage (minimum 167V), clamping voltage (application-dependent), peak pulse current (minimum 18.7A), and peak pulse power (minimum 5000W). All substitute parts must maintain ROHS3 compliance and unlimited MSL rating.

Q: Are there operating temperature differences between the substitute parts?

A: The 5KP150CE3/TR13, 15KPA150CA, 5KP150CA, and 5KP150CA-B all specify operating temperature range of -55°C to 175°C (TJ). The BZW50-150B does not provide operating temperature specification in the available data. For applications requiring confirmed temperature performance across the full range, the Littelfuse or MDE parts provide explicit specification.

Q: What packaging options are available for the 150V TVS diode class?

A: The 5KP150CE3/TR13 is supplied in Tape & Reel (TR) format. Substitute parts are available in multiple packaging formats: 5KP150CA in Cut Tape (CT), 5KP150CA-B in Bulk, 15KPA150CA in Bulk, and BZW50-150B in Cut Tape (CT). Packaging selection depends on assembly requirements and procurement volume. All parts use Through Hole axial mounting with either P600 or R-6 package configuration.

Q: How does clamping voltage affect TVS diode selection?

A: Clamping voltage determines the maximum voltage that appears across the protected circuit during a transient event. The 5KP150CE3/TR13 clamps at 268V maximum. Substitute parts offer varying clamping voltages: 5KP150CA at 243V, 15KPA150CA at 241.9V, and BZW50-150B at 343V. Lower clamping voltage provides better transient suppression but may require verification against circuit protection requirements. Higher clamping voltage offers more margin but less aggressive suppression.
