Substitute Part Grouping Explanation

Substitute parts for the BZT52B13 are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are:

• Zener Voltage (Vz): Must be 13 V nominal
• Tolerance: Must be ±2%
• Maximum Power Dissipation: Must be 500 mW
• Impedance (Zzt): Must be 30 Ohms maximum
• Reverse Leakage Current: Must be 90 nA @ 8 V
• Forward Voltage: Must be 1 V maximum @ 10 mA
• Operating Temperature: Must support 150°C junction temperature
• Package: Must be SOD-123F
• Mounting Type: Must be Surface Mount

Parts meeting all these parameters are classified as parametric equivalents and are directly interchangeable in circuit applications without design modification.

Frequently Asked Questions (FAQ)

Q: Can BZT52B13 RHG be used as a direct replacement for BZT52B13?

A: Yes. The BZT52B13 RHG meets all electrical and mechanical parameters of the BZT52B13, including zener voltage, power rating, impedance, leakage current, forward voltage, operating temperature, and package specification. No circuit design changes are required.

Q: Are there any differences in compliance or certifications between these parts?

A: No. Both parts carry identical RoHS3 compliance and REACH unaffected status, confirming equivalent regulatory standing for use in regulated applications.

Q: What is the significance of the "RHG" suffix in the part number?

A: The "RHG" suffix indicates a variant designation from Taiwan Semiconductor Corporation. This designation does not alter the electrical performance or package specification; it reflects internal manufacturing or distribution tracking.

Q: Can these parts be mixed in the same production batch?

A: Yes. Since both parts are parametrically identical and share the same package, they can be used interchangeably within the same assembly without affecting circuit performance or reliability.

Q: What should be verified when substituting between these parts?

A: Verify that the PCB footprint matches the SOD-123F package specification and that the circuit design operates within the specified zener voltage tolerance of ±2% at 13 V nominal.
