Single Zener Diodes Procurement Notes

Verify that the ordering suffix /TR indicates tape and reel packaging as specified in the datasheet mechanical section. Confirm the B suffix corresponds to the 5% voltage tolerance. Ensure the component meets MIL-PRF-19500/115 qualification requirements for the intended application environment.

Single Zener Diodes Selection Notes

Select this component when a 20 V Zener reference is required in a through-hole DO-41 package. The 1 W power dissipation rating supports higher current loads compared to lower-power series. The wide operating temperature range makes it suitable for extreme environmental conditions where commercial alternatives may fail.

Single Zener Diodes Part Context
