Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as multiple entities including Microchip and Cobham have produced this part number. Confirm package integrity and lead condition upon receipt. Ensure compliance with relevant environmental directives if required by your application standards. Check for any process change notifications regarding packaging or material composition before final integration.

Single Zener Diodes Selection Notes

Select this component when a fixed 11 V reference is needed with moderate power handling capabilities. The DO-35 package suits automated through-hole assembly processes. Consider the 9.5 Ω impedance for dynamic load variations. Ensure the circuit design accounts for the 500 mW thermal limit under worst-case ambient conditions to maintain reliability over the specified temperature range.

Single Zener Diodes Part Context

This component belongs to the standard 1N962 series of Zener diodes, widely used in legacy and modern electronics for basic voltage clamping. The 'B' suffix typically denotes the ±5% tolerance band, distinguishing it from wider tolerance variants. The 'TR' suffix indicates tape and reel packaging for high-volume manufacturing efficiency.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N962B parts with identical electrical ratings. Verify pinout compatibility and package dimensions (DO-35) for mechanical fit. Ensure equivalent thermal performance and voltage stability curves match the original design requirements.
