Single Zener Diodes Procurement Notes

Verify RoHS compliance status and specific manufacturing date codes upon order confirmation. Confirm package orientation markings match PCB silkscreen requirements. Ensure storage conditions adhere to moisture sensitivity level guidelines if applicable. Check for any recent product change notices that may affect pinout or electrical parameters before finalizing design integration.

Single Zener Diodes Selection Notes

Select this component when a 13 V reference is needed with 1.5 W power capability in an SMA package. Compare Zener impedance and leakage current against circuit sensitivity requirements. Consider thermal management needs due to higher power dissipation compared to smaller packages. Verify that the ±5% tolerance meets the system's voltage accuracy constraints.

Single Zener Diodes Part Context

This part belongs to Comchip Technology's CZRA series of high-power Zener diodes. The series offers various voltage ratings from 6.2 V to 200 V in the DO-214AC package. These diodes are characterized by low leakage and robust construction, making them suitable for demanding environments where standard small-signal diodes would fail due to power or thermal limitations.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 13 V Zener voltage, 1.5 W power rating, and DO-214AC package. Verify equivalent Zener impedance and leakage specifications. Cross-reference with other manufacturers' SMA-rated Zener diodes ensuring identical pinout and thermal characteristics.
