CMHZ5222B BK PBFREE

Single Zener Diodes Overview

The CMHZ5222B BK PBFREE is a surface-mount silicon Zener diode from Central Semiconductor, housed in an SOD-123 package. It provides a nominal Zener voltage of 2.5V with a ±5% tolerance (range 2.375V to 2.625V). The device dissipates up to 500mW at 75°C and operates within a junction temperature range of -65°C to +150°C. Electrical characteristics include a maximum impedance of 30Ω at the test current of 20mA and a reverse leakage current of 100µA at 1.0V.

Single Zener Diodes Procurement Notes

Verify the exact part number against manufacturer documentation to confirm availability status. Check for specific suffix requirements regarding lead-free compliance or tape-and-reel packaging if required for production. Confirm that the BK marking code matches the intended component variant before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a precise 2.5V reference is needed in a low-power surface-mount design. Ensure the application current does not exceed the 20mA test current significantly to maintain accuracy. Consider the thermal resistance of 150°C/W when designing heat dissipation paths for enclosed environments.

Single Zener Diodes Part Context

This device belongs to the CMHZ5221B through CMHZ5267B series, which covers Zener voltages from 2.4V to 75V. All members share the same SOD-123 physical footprint and 500mW power rating, differing primarily in their breakdown voltage and associated electrical parameters such as impedance and leakage current.

Single Zener Diodes Replacement Considerations

No official replacement part numbers are listed in the provided datasheet for this specific model. Consult the manufacturer directly for potential alternatives if this component becomes obsolete.
