Single Zener Diodes Procurement Notes

Verify the specific part number configuration upon ordering. Confirm that the 'TR8' suffix corresponds to the required tape and reel packaging format. Ensure compatibility with the T-18 axial lead package dimensions for your printed circuit board layout. Check for any recent product change notifications or discontinuance alerts associated with this Microsemi/Microchip component series before finalizing procurement plans.

Single Zener Diodes Selection Notes

Select this component when a 6.0 V Zener voltage with tight ±5% tolerance is required. The 5-watt power rating allows for operation at high DC currents provided adequate heat sinking is utilized. Consider the thermal resistance specifications for your specific mounting method, whether direct lead mounting or FR4 PCB attachment. Verify that the operating environment falls within the specified -65°C to +150°C temperature range.
