1N4469C

Single Zener Diodes Overview

The Microchip Technology 1N4469C is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 15 V with a tight tolerance of ±2%. The device has a power dissipation rating of 1.5 W and operates in a DO-204AL (DO-41) through-hole package. Key electrical parameters include a maximum dynamic impedance of 9 Ohms and a reverse leakage current of 50 nA at 12 V. The junction temperature range extends from -65°C to 175°C, supporting robust performance in demanding environments.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a standard tolerance of ±2%.
• Supports operation over a wide temperature range up to 175°C junction temperature.
• Utilizes glass passivation for environmental stability.

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• Clamping applications

Single Zener Diodes Procurement Notes

Verify the specific suffix 'C' indicates the ±2% tolerance variant when sourcing. Confirm the manufacturer is Microchip Technology, as this part number lineage originates from legacy manufacturers like Microsemi. Ensure the DO-204AL package matches your PCB footprint requirements. Check for RoHS compliance status if required by your assembly specifications.

Single Zener Diodes Selection Notes

Select this component when a stable 15 V reference with high precision is required. The 1.5 W power rating allows for higher current handling compared to smaller signal diodes. Consider the 9 Ohm impedance for low-noise regulation needs. The wide operating temperature range makes it suitable for industrial or automotive contexts where thermal stability is critical.

Single Zener Diodes Part Context

This component belongs to the 1N4469 series of glass-passivated silicon Zener diodes. Originally developed by Microsemi Corporation, the product line was acquired by Microchip Technology. These diodes are characterized by their rugged construction and consistent performance across varying thermal conditions, serving as reliable regulators in discrete electronic designs.

Single Zener Diodes Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with generic 1N4469 equivalents only if they meet the specific ±2% tolerance and 1.5 W power rating requirements.
