1N2999A

Overview

The 1N2999A is a 56V Zener diode with a 10W power rating and ±5% tolerance. It features a maximum impedance of 16 Ohms and operates in the DO-213AA (DO-4) stud-mount package.

Feature Summary

Provides stable voltage regulation at 56V
Designed for high-power dissipation up to 10W
Utilizes robust stud-mount construction for thermal management

Applications

Voltage regulation circuits
Power supply protection
Overvoltage clamping applications

Procurement Notes

Verify manufacturer documentation confirms Microchip Technology as the current producer, noting historical production by Microsemi. Ensure the specific suffix 'A' denotes the required ±5% tolerance grade. Confirm the DO-213AA package style matches system mounting requirements before procurement.

Selection Notes

Select this component when a 56V reference with 10W capability is needed. The stud-mount format requires compatible heatsinking infrastructure. Verify that the 16 Ohm impedance meets circuit sensitivity requirements compared to lower-power surface mount alternatives.

Part Context

This device belongs to the standard 1N2999 series of high-power Zener diodes. It serves as a rugged voltage reference solution for industrial environments where through-hole or chassis mounting is preferred over surface-mount technologies.

Replacement Considerations

Cross-reference with JAN1N2999A for military-grade equivalents. Verify compatibility with other 1N2999A variants from different manufacturers regarding pinout and thermal resistance specifications.
