1N4716

Overview

The Microchip Technology 1N4716 is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 68 V with a standard tolerance of 5%. The device operates in a through-hole DO-35 (DO-204AH) axial-leaded glass package, providing a maximum DC power dissipation of 500 mW at +50°C. It supports an operating temperature range from -65°C to +175°C and includes an internal metallurgical bond option for enhanced reliability.

Feature Summary

• JEDEC registered 1N4678 thru 1N4717 series compliance
• Internal metallurgical bond construction for durability
• Wide operating temperature range suitable for harsh environments

Applications

• Voltage reference circuits requiring stable regulation
• Overvoltage protection in electronic systems
• Temperature compensated zener reference designs

Procurement Notes

Verify the specific suffix requirements when ordering, as options such as -1 denote internal metallurgical bonding similar to military specifications. Confirm screening standards like MIL-PRF-19500 if applicable to your design. Ensure the DO-35 package dimensions align with your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component for low-power regulation tasks where a 68 V reference is required. Consider the 500 mW power rating and ensure adequate thermal management within the specified -65°C to +175°C range. The axial leaded format is ideal for breadboarding or through-hole manufacturing processes rather than surface mount assembly.

Part Context

This part belongs to the 1N47xx series of 500 mW axial-leaded Zener diodes manufactured by Microchip Technology. The series covers a broad voltage selection from 1.8 V to 43 V in standard configurations, though specific higher voltage variants like the 1N4716 extend beyond the base 1N4700-1N4752 range often cited for lower power limits.

Replacement Considerations

Compatible substitutes include other manufacturers' 1N4716 equivalents meeting JEDEC registration standards. Verify that replacement parts maintain the 68 V nominal voltage, 5% tolerance, and DO-35 package footprint to ensure direct interchangeability in existing circuit designs.
