1N2814A

Overview

The Microchip Technology 1N2814A is a single Zener diode designed for high-power voltage regulation applications. It features a nominal Zener voltage of 16 V with a tolerance of ±10%. The device supports a maximum power dissipation of 50 W and utilizes a TO-204AD (TO-3) through-hole package. Key electrical characteristics include a reverse leakage current of 10 µA at 9.9 V, a forward voltage of 1.5 V at 10 A, and a maximum impedance of 1.1 Ohms. It operates within a temperature range of -65°C to 175°C.

Feature Summary

• Provides stable voltage regulation in high-power circuits
• Capable of handling significant thermal loads via robust packaging
• Designed for reliable operation across extreme temperature environments

Applications

• High-power voltage reference circuits
• Industrial power supply regulation
• Overvoltage protection systems

Procurement Notes

Verify the manufacturer part number matches exactly 1N2814A from Microchip Technology. Confirm the package type is TO-204AD (TO-3). Check RoHS status as it may be non-compliant depending on the specific production batch. Ensure the supplier provides valid traceability documentation for critical industrial or aerospace applications.

Selection Notes

Select this component when a 16 V Zener voltage with 50 W power rating is required. The TO-204AD package necessitates appropriate heatsinking solutions due to high power dissipation. Consider the ±10% tolerance if tighter voltage regulation is needed, which would require alternative part numbers. Verify that the operating temperature range meets the specific environmental requirements of the target application.

Part Context

The 1N2814A belongs to the family of silicon Zener diodes manufactured by Microchip Technology. These devices are typically used in rugged electronic systems where high power handling and wide temperature stability are essential. The TO-204AD package is a standard hermetic metal case often used in military and aerospace grade components.
