1N2807RB

Overview

The Microchip Technology 1N2807RB is a high-power Zener diode belonging to the JEDEC registered 1N2804B through 1N2846B series. It provides voltage regulation with a nominal Zener voltage of 9.1V and a tolerance of 20%. The device is designed for operation up to 50W, leveraging low thermal resistance when paired with adequate mounting and heat sinking. It utilizes a TO-204AD (TO-3) flange mount package, which is hermetically sealed. The component is constructed from silicon and features a unidirectional configuration with two terminals.

Feature Summary

• Capable of handling up to 50W power dissipation under proper thermal management conditions
• Hermetically sealed metal flange mount construction for environmental protection
• Low thermal resistance design facilitating efficient heat transfer

Applications

• High power voltage regulation circuits
• Military qualified electronic systems requiring JAN, JANTX, or JANTXV levels
• Industrial equipment requiring robust power management components

Procurement Notes

Verify the specific qualification level required for your application, as this series is available in JAN, JANTX, and JANTXV military qualifications. Confirm that the ordering suffix matches the desired reliability grade. Ensure compatibility with the TO-204AD mechanical footprint during integration. Cross-reference the datasheet for exact thermal characteristics to validate heat sink requirements for sustained 50W operation.

Selection Notes

Select this component when a high-power, ruggedized Zener diode is necessary for critical applications. The TO-3 package offers superior thermal performance compared to smaller packages. Consider the 20% voltage tolerance when designing precision regulation loops. Verify that the system can accommodate the physical size and mounting style of the flange mount package.

Part Context

This part belongs to the Microchip 1N2804B–1N2846B series of 50W Zener diodes. These devices are JEDEC registered and offer a broad range of voltage values from 3.9V to 200V.
