Single Zener Diodes Procurement Notes

Verify the specific suffix and package variant against the official datasheet, as distributor listings may contain conflicting specifications regarding power ratings or voltage tolerances. Confirm RoHS compliance status directly from the manufacturer's documentation before integration into final assemblies.

Single Zener Diodes Selection Notes

Select this component when a 1 W Zener diode is required in an SOD-128 form factor. Ensure the circuit design accommodates the 40 mA test current for accurate voltage regulation. Compare thermal management requirements against the 150°C maximum junction temperature limit for high-power environments.

Single Zener Diodes Part Context

This part belongs to ROHM's PMDTM series of Zener diodes, which are optimized for space-constrained surface-mount designs. The series provides various voltage options while maintaining consistent package dimensions and thermal performance characteristics for standardized PCB layouts.

Single Zener Diodes Replacement Considerations

Cross-reference with other 16.2 V, 1 W Zener diodes in SOD-128 packages. Verify pinout compatibility and thermal resistance values to ensure equivalent performance in existing designs.
