Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as ON Semiconductor also lists this part number. Confirm RoHS compliance status and exact tolerance class against the official datasheet before procurement. Ensure the package matches the required DO-35 form factor for your circuit design.

Single Zener Diodes Selection Notes

Select this component when a 13 V regulation point is required in a standard through-hole configuration. Consider the 13 Ω dynamic impedance for noise sensitivity requirements. Verify that the 0.5 W power rating accommodates the expected current draw without exceeding thermal limits.

Single Zener Diodes Part Context

This component belongs to the standard series of half-watt Zener diodes widely used in discrete semiconductor applications. It serves as a fundamental passive element for establishing fixed voltage nodes in analog and digital logic circuits.

Single Zener Diodes Replacement Considerations

Equivalent parts include JANTX1N964D-1 and JANTX1N964C-1 from Microchip/Microsemi. These alternatives share the same 13 V specification and DO-35 package but may differ in military-grade qualification or specific tolerance classes.
