Single Zener Diodes Procurement Notes

Verify the manufacturer marking on the component body to confirm Microchip Technology origin, as this part number is widely produced by multiple vendors. Ensure the DO-35 package dimensions match your PCB footprint requirements. Check datasheets from specific distributors for exact tolerance grades and thermal derating curves relevant to your operating environment.

Single Zener Diodes Selection Notes

Select this component when a 19V Zener voltage is required with moderate precision. Consider the 250 mW power limit when designing heat dissipation paths. Compare tolerance specifications against other manufacturers if tighter voltage accuracy is needed for critical reference applications. Ensure the operating temperature range aligns with system constraints.

Single Zener Diodes Part Context

The 1N768 belongs to the standard 1N series of Zener diodes, a legacy designation widely adopted across the semiconductor industry.
