Engineering Selection Recommendations

The BZT52B75JS-TP is the direct substitute for the obsolete BZT52B75S-TP. Selection of the substitute part is based on the following factors:

Product Status: The BZT52B75JS-TP carries active product status, ensuring long-term availability and manufacturing support compared to the obsolete BZT52B75S-TP.

Electrical Equivalence: All critical electrical parameters are identical between the main part and substitute, including zener voltage, power rating, impedance, leakage current, and forward voltage characteristics.

Compliance: Both parts maintain ROHS3 compliance and MSL 1 moisture sensitivity rating, satisfying environmental and handling requirements.

Operating Temperature: The substitute part operates across -55°C to 150°C, which covers the majority of industrial and commercial applications. Applications requiring operation above 150°C up to 175°C must evaluate thermal requirements against the substitute's maximum rating.

Packaging: The substitute is supplied in Tape & Reel format, standard for high-volume surface mount assembly operations.

Frequently Asked Questions (FAQ)

Q: Can BZT52B75JS-TP be used as a direct replacement for BZT52B75S-TP?

A: Yes. The BZT52B75JS-TP is electrically and mechanically equivalent to the BZT52B75S-TP. All electrical specifications, package type, and compliance certifications are identical.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and operating temperature range. The BZT52B75S-TP is obsolete with a -55°C to 175°C operating range, while the BZT52B75JS-TP is active with a -55°C to 150°C operating range. The substitute is supplied in Tape & Reel packaging.

Q: Are there any circuit design changes required when switching to BZT52B75JS-TP?

A: No circuit design changes are required. The electrical characteristics are identical, and the SOD-323 package footprint is the same.

Q: What is the maximum operating temperature for the substitute part?

A: The BZT52B75JS-TP operates to a maximum junction temperature of 150°C. Applications requiring operation above this temperature must use the original BZT52B75S-TP or identify an alternative part rated to 175°C.

Q: Is the substitute part RoHS compliant?

A: Yes. The BZT52B75JS-TP is ROHS3 compliant and carries MSL 1 moisture sensitivity rating, identical to the main part.

Q: What packaging format is the substitute supplied in?

A: The BZT52B75JS-TP is supplied in Tape & Reel (TR) format, standard for automated surface mount assembly.
