Single Zener Diodes Procurement Notes

Verify that the specific suffix 'R3G' corresponds to the standard tape and reel packing configuration detailed in the official datasheet. Confirm that the component meets JESD 201 class 2 whisker test requirements and moisture sensitivity level 1 specifications as documented by the manufacturer.

Single Zener Diodes Selection Notes

Select this component when a 30 V reference is required in a compact SMA footprint. Ensure the application circuit can accommodate the specified 1 W power dissipation and verify that the operating environment remains within the -55 °C to +175 °C junction temperature limits defined in the absolute maximum ratings.

Single Zener Diodes Part Context

This part belongs to the 1PGSMA series, which covers Zener voltages from 10 V to 200 V. All devices in this series share the same DO-214AC mechanical outline and general electrical characteristics, differentiated primarily by their specific breakdown voltage and corresponding marking codes.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 30 V Zener diodes in the DO-214AC package. Verify that substitute components match the 1 W power rating, 40 Ω impedance, and 1 µA leakage specifications to ensure functional compatibility.
