1N4619C-1

Single Zener Diodes Overview

The Microchip Technology 1N4619C-1 is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 3 V with a tight tolerance of ±2%. The device operates in the DO-35 axial leaded package and supports a DC power dissipation of 500 mW at +50°C, with derating required above this temperature. Electrical characteristics include a maximum reverse leakage current of 400 nA and a Zener impedance of 1600 ohms. The component is rated for an operating temperature range from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a 3 V nominal breakdown voltage and ±2% tolerance.
• Engineered for high-temperature reliability with an extended operating range up to +175°C.
• Utilizes a hermetically sealed glass DO-35 package suitable for harsh environments.

Single Zener Diodes Applications

• Military aerospace electronic systems
• Spacecraft power management circuits
• High-reliability industrial control equipment

Single Zener Diodes Procurement Notes

Verify that the specific part number suffix matches the required military qualification level. Confirm package style and testing standards against project specifications. Ensure compatibility with existing supply chain requirements for radiation-hardened or high-reliability components. Check for any specific lot traceability documentation needs.

Single Zener Diodes Selection Notes

Select this component when strict voltage accuracy and extreme temperature stability are required. The ±2% tolerance offers tighter regulation than standard commercial variants. Consider the DO-35 package constraints for board space and thermal management. Evaluate the need for hermetic sealing based on environmental exposure levels.

Single Zener Diodes Part Context

This device belongs to the 1N46xx series of Zener diodes manufactured by Microchip Technology under the Microsemi brand. The series covers various voltage ratings within the low-voltage range.
