SMBJ150CA-M3/5B Equivalent & Substitute Parts Reference
Part Overview
SMBJ150CA-M3/5B is a Transient Voltage Suppressor (TVS) diode from Vishay General Semiconductor - Diodes Division, categorized under Zener-type, surface-mount TVS diodes in DO-214AA (SMBJ) packaging. It offers 150V reverse standoff voltage, 243V clamping voltage, and 2.5A peak pulse current with 600W peak pulse power. The device is actively produced, ROHS3 compliant, and intended for general-purpose transient voltage protection applications.
Alternative models are necessary when supply shortages, lead time constraints, or sourcing preferences exist, while maintaining electrical and mechanical compatibility in the target system.

Substitute Part Grouping Explanation
Substitution selection for SMBJ150CA-M3/5B follows strict equivalence of the following key parameters: device type (Zener, TVS diode), bidirectional protection, voltage ratings (reverse standoff, breakdown, and clamping), peak pulse current, peak pulse power, package/case (DO-214AA, SMB), surface-mount configuration, regulatory compliance (ROHS3, REACH), and product status (active). Only parts matching these criteria are considered substitutes. Alternative voltage ratings are listed only if explicitly designated as manufacturer-recommended alternatives.

Engineering Selection Recommendations
All listed substitutes for SMBJ150CA-M3/5B are designated as active and ROHS3 compliant, with a moisture sensitivity level of 1 (unlimited) and REACH unaffected status. The package/case (DO-214AA, SMB), mounting type, and general product compliance are matched across substitutes. Selection between these alternatives may be made based on source availability or inventory, strictly within the listed compliance and certification criteria.
Frequently Asked Questions (FAQ)
Q1: What are the essential parameters for selecting a substitute for SMBJ150CA-M3/5B?
A1: Substitute TVS diodes must have matching reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, peak pulse power, number of bidirectional channels, surface mount configuration, package/case type (DO-214AA, SMB), operating temperature range, and regulatory certifications.
Q2: Can any TVS diode in DO-214AA (SMB) package substitute for SMBJ150CA-M3/5B?
A2: Only TVS diodes in the DO-214AA (SMB) package that match or exceed the electrical parameters of the SMBJ150CA-M3/5B and comply with ROHS3, REACH, and MSL1 status are accepted as substitutes.
Q3: How does package compatibility impact substitution?
A3: Both mechanical and footprint compatibility must be maintained. All listed substitutes use DO-214AA (SMB) package to ensure direct replacement on the same PCB footprint.
Q4: Is it necessary to match the exact voltage ratings?
A4: Exact voltage ratings must be matched for direct substitution unless the manufacturer specifies otherwise in their recommended alternatives, such as in the SMBJ130CA listing. Otherwise, use parts with the same voltage ratings as SMBJ150CA-M3/5B.
Q5: Are all substitute parts compliant with industry regulations?
A5: All substitutes listed for SMBJ150CA-M3/5B are ROHS3 compliant, REACH unaffected, and have MSL1 (unlimited) status.
