SMBJ150A-TP Equivalent & Substitute Parts

Part Overview

The SMBJ150A-TP is a unidirectional transient voltage suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection in surface-mount applications. This component operates with a 150V reverse standoff voltage and 243V maximum clamping voltage, delivering 2.5A peak pulse current in a DO-214AA (SMB) package. The part is active in production status and fully RoHS3 compliant with unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified when electrical performance parameters and mechanical compatibility remain within acceptable tolerances for the application, enabling procurement flexibility and supply chain continuity.

Engineering Selection Recommendations

All substitute parts listed maintain full electrical and mechanical equivalence to the SMBJ150A-TP. Selection among these alternatives is determined by:

Compliance & Certification: All candidates are RoHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) ratings, meeting standard industrial and commercial requirements.

Product Status: All parts maintain active production status, ensuring long-term availability and supply chain stability.

Operating Temperature Consideration: The SMBJ150A-TP supports an extended upper temperature limit of 175°C (TJ) compared to 150°C for SMBJ150A-13-F and SMBJ150A-E3/52, and 150°C for SMBJ150A (MDD). Applications requiring operation above 150°C should prioritize the SMBJ150A-TP or verify thermal requirements against substitute specifications.

Packaging & Availability: SMBJ150A-13-F (Diodes Incorporated) is supplied in Tape & Reel format; SMBJ150A-E3/52 (Vishay) is supplied in Cut Tape & Digi-Reel format; SMBJ150A (MDD) packaging is unspecified. Procurement requirements may influence selection based on reel format compatibility with assembly equipment.

Frequently Asked Questions (FAQ)

Q: Can SMBJ150A-13-F replace SMBJ150A-TP in all applications?

A: Yes, for applications operating within -55 to 150°C. The SMBJ150A-13-F maintains identical electrical specifications (150V standoff, 243V clamp, 2.5A peak pulse) and DO-214AA package compatibility. Applications requiring operation above 150°C should confirm thermal performance requirements.

Q: What is the difference between SMBJ150A (MDD) and SMBJ150A-E3/52 (Vishay)?

A: Both parts are electrically identical with 150V standoff and 243V clamping specifications. The primary difference is manufacturer and packaging format. SMBJ150A-E3/52 is supplied in Cut Tape & Digi-Reel format by Vishay General Semiconductor. SMBJ150A (MDD) packaging format is unspecified. Verify packaging compatibility with your assembly process.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitutes—SMBJ150A (MDD), SMBJ150A-13-F (Diodes Incorporated), and SMBJ150A-E3/52 (Vishay)—are RoHS3 compliant with REACH unaffected status and MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Does operating temperature range affect substitution eligibility?

A: Operating temperature range should be evaluated against application requirements. The SMBJ150A-TP supports -55 to 175°C (TJ). Substitute parts SMBJ150A-13-F and SMBJ150A-E3/52 support -55 to 150°C, while SMBJ150A (MDD) supports -50 to 150°C. For applications requiring sustained operation above 150°C, the SMBJ150A-TP is the appropriate selection.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All substitute parts share identical DO-214AA (SMB) package geometry and electrical specifications, enabling direct footprint compatibility and functional interchangeability in circuit design.
