Single Zener Diodes Procurement Notes

Verify that the suffix 'H' indicates AEC-Q101 qualification and 'G' denotes halogen-free green compound packaging. Confirm the specific marking code matches the datasheet requirements. Ensure the component meets RoHS directives and JESD 201 class 2 whisker test standards before final procurement authorization.

Single Zener Diodes Selection Notes

Select this component when a 110 V Zener reference is required in a compact SMA footprint. Consider the low leakage current specification for sensitive circuits. Evaluate the thermal derating curves against the expected ambient operating conditions to ensure power dissipation limits are not exceeded during continuous operation.

Single Zener Diodes Part Context

This part belongs to the 1SMA4737–1SMA200Z series from Taiwan Semiconductor Corporation. The series covers a wide voltage range from 7.5 V to 200 V in the DO-214AC package. The 1SMA110Z variant specifically targets higher voltage regulation needs within this standardized surface-mount family.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering DO-214AC Zener diodes rated at 110 V. Verify matching electrical parameters such as dynamic impedance and leakage current. Ensure mechanical dimensions and polarity markings are compatible with existing PCB layouts.
