JAN1N4486C

Single Zener Diodes Overview

The JAN1N4486C is a military-qualified Zener voltage regulator diode manufactured by Microchip Technology. It operates within the 1N4460–1N4496 series and is qualified to MIL-PRF-19500/406 standards. The device features a nominal Zener voltage of 75 V with a 2% tolerance, indicated by the 'C' suffix. It has a maximum steady-state power dissipation of 1.5 W at a lead temperature of +112 °C. The unit utilizes a DO-41 axial through-hole package with a hermetically sealed voidless glass construction.

Single Zener Diodes Feature Summary

• Hermetically sealed voidless glass package with internal metallurgical bonds for high reliability
• Qualified per MIL-PRF-19500/406 for critical applications where failure cannot be tolerated
• Inherently radiation hard as described in Microsemi MicroNote 050
• Non-sensitive to electrostatic discharge (ESD) per MIL-STD-750 method 1020

Single Zener Diodes Applications

• High-reliability voltage regulation circuits
• Military and aerospace electronic systems
• Radiation-hardened circuit designs
• Precision reference voltage generation

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required qualification level and tolerance. Confirm RoHS compliance status, as non-RoHS versions are standard for this military grade. Ensure the procurement documentation includes the relevant military specification references. Check for any specific packaging requirements such as tape and reel options if applicable to the assembly process.

Single Zener Diodes Selection Notes

Select this component when a 75 V Zener voltage with tight 2% tolerance is required in a ruggedized environment. Consider the 1.5 W power rating and thermal resistance characteristics for heat dissipation planning. Verify compatibility with the operating temperature range of -65 °C to +175 °C. Ensure the DO-41 axial leaded package fits the mechanical constraints of the target printed circuit board layout.

Single Zener Diodes Part Context

This part belongs to the 1N4460–1N4496 series of 1.5 Watt glass Zener diodes. The series offers a wide selection of voltages from 3.3 to 200 V. The JAN1N4486C specifically represents the 75 V variant within this lineup. Other variants in the series share similar construction but differ in voltage ratings and corresponding test currents.

Single Zener Diodes Replacement Considerations

Equivalent parts include JANTX1N4486C and JANTXV1N4486C, which offer different reliability levels within the same electrical specifications.
