Single Zener Diodes Procurement Notes

Verify the specific suffix /61 indicates the 1800 units per reel tape configuration. Confirm that the HE3 designation ensures RoHS compliance and halogen-free status. Check for any recent product change notifications or discontinuation notices from the manufacturer before finalizing procurement plans.

Single Zener Diodes Selection Notes

Select this component when a 30 V reference is required in a compact SMA footprint. Ensure the application accounts for the 40 Ω dynamic impedance and 5 µA leakage limits. Verify that the 1 W power dissipation rating aligns with the thermal environment and operating conditions of the target circuit design.

Single Zener Diodes Part Context

This part belongs to the SML47 series of surface mount Zener diodes. The series covers a wide voltage range from 3.3 V to 100 V. All devices share the same DO-214AC package and mechanical specifications while varying in electrical parameters such as test current and impedance based on the voltage rating.
