Engineering Selection Recommendations

All identified substitute parts maintain active product status and full compliance with RoHS3 and REACH regulations, ensuring regulatory continuity with the original SMBJ150CE3/TR13.

SMBJ150CA (MDD): This substitute shares identical reverse standoff voltage (150V) and breakdown voltage (167V) specifications. The clamping voltage is reduced to 243V with increased peak pulse current of 2.5A. Operating temperature range is -50 to 150°C. This part is suitable for applications where the lower clamping voltage and higher current capacity provide adequate protection margins.

SMBJ150CA-13-F (Diodes Incorporated): This substitute maintains the same electrical specifications as the MDD variant with 243V clamping and 2.5A peak pulse current. Operating temperature range extends to -55°C minimum. The part is supplied on tape and reel in SMB package format. This option is appropriate for applications requiring extended low-temperature operation.

SMBJ150CA-TP (Micro Commercial Co): This substitute provides identical electrical performance to the Diodes Incorporated variant with 243V clamping and 2.5A peak pulse current. The operating temperature range extends to -55 to 175°C, offering the widest high-temperature capability among all substitutes. The part is supplied on tape and reel in DO-214AA (SMB) format.

All substitute parts are qualified for general-purpose overvoltage protection applications and maintain compatibility with the DO-214AA surface-mount package format.

Frequently Asked Questions (FAQ)

Q: Can SMBJ150CA (MDD) be used as a direct replacement for SMBJ150CE3/TR13?

A: Yes. Both parts share the same 150V reverse standoff voltage, 167V minimum breakdown voltage, and DO-214AA package format. The SMBJ150CA features a lower clamping voltage (243V versus 268V) and higher peak pulse current (2.5A versus 2.2A), making it suitable for general-purpose protection applications. Operating temperature range differs (-50 to 150°C versus -65 to 150°C).

Q: What is the difference between SMBJ150CA-13-F and SMBJ150CA-TP?

A: Both parts share identical electrical specifications (150V standoff, 167V breakdown, 243V clamping, 2.5A peak pulse current). The primary difference is operating temperature range: SMBJ150CA-13-F operates from -55 to 150°C, while SMBJ150CA-TP operates from -55 to 175°C. SMBJ150CA-TP is recommended for applications requiring extended high-temperature performance.

Q: Are all substitute parts available in tape and reel packaging?

A: SMBJ150CA (MDD) packaging information is not specified in the provided data. SMBJ150CA-13-F (Diodes Incorporated) and SMBJ150CA-TP (Micro Commercial Co) are both supplied on tape and reel. The original SMBJ150CE3/TR13 is also supplied on tape and reel.

Q: What is the significance of the lower clamping voltage in substitute parts?

A: The substitute parts feature a maximum clamping voltage of 243V compared to 268V in the original part. Lower clamping voltage provides tighter voltage regulation during transient events, which may be beneficial in sensitive applications. System design must confirm that 243V clamping is acceptable for the protected circuit.

Q: Do all parts meet the same regulatory requirements?

A: Yes. All parts listed are RoHS3 compliant and REACH unaffected, maintaining regulatory continuity with the original SMBJ150CE3/TR13. All parts carry moisture sensitivity level 1 (unlimited), indicating no special moisture handling requirements.

Q: Which substitute part offers the widest operating temperature range?

A: SMBJ150CA-TP (Micro Commercial Co) provides the widest operating temperature range at -55 to 175°C, compared to -65 to 150°C for the original part and -50 to 150°C for the MDD variant.
