1N4717-TP

Single Zener Diodes Overview

The MCC 1N4717-TP is a 500mW silicon planar Zener diode housed in a hermetically sealed DO-35 glass package. It provides a nominal Zener voltage of 43V with a standard tolerance of ±5%. The device features a very sharp reverse characteristic and operates within a junction temperature range of -65°C to +200°C. Maximum ratings include a steady-state power dissipation of 500mW at lead temperatures below 75°C, a thermal resistance of 300 K/W, and a maximum forward voltage of 1.5V at 100mA.

Single Zener Diodes Feature Summary

• Hermetically sealed double slug type glass construction for high reliability
• Very sharp reverse characteristic for precise voltage regulation
• Lead-free finish compliant with RoHS directives

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection for sensitive electronic components
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify the specific suffix (e.g., -TP for Tape & Reel) against current ordering information to confirm packaging format. Confirm compliance with RoHS standards and check for any recent Product Change Notices regarding manufacturing updates or material substitutions before finalizing procurement plans.

Single Zener Diodes Selection Notes

Select this component when a 43V regulation point is required in a compact axial leaded form factor. Ensure the application environment supports the specified operating temperature range up to 200°C. Verify that the 500mW power dissipation rating aligns with the expected thermal conditions and surge requirements of the target circuit design.

Single Zener Diodes Part Context

This part belongs to the 1N4678 through 1N4717 series of 500mW silicon Zener diodes manufactured by Micro Commercial Components. The series covers a wide voltage range from 1.8V to 43V, all sharing similar mechanical and electrical characteristics within the DO-35 package family.

Single Zener Diodes Replacement Considerations

Direct replacements must match the 43V nominal voltage, 500mW power rating, and DO-35 axial package. Verify that substitute devices offer equivalent reverse leakage currents and thermal resistance values to ensure circuit performance parity.
