Overview
The 1N2830A is a hermetically sealed silicon Zener diode manufactured by Microchip Technology. It features a nominal Zener voltage of 50V with a tolerance of ±10% and a maximum power dissipation of 50W. The device utilizes a TO-204AD (TO-3) package with two pins, where the case is electrically connected to the anode. It supports a wide operating temperature range from -65°C to +175°C and is classified as a single unidirectional component.
Feature Summary
- Hermetically sealed construction in a metal TO-3 package for environmental protection
- High power handling capability of 50W for robust voltage regulation
- Wide thermal operating range extending up to 175°C
Applications
- High-power voltage regulation circuits
- Overvoltage protection systems
- Reference voltage generation in industrial equipment
Procurement Notes
Verify RoHS compliance status prior to procurement, as this specific part number may not meet current environmental directives. Confirm that the TO-3 package mounting requirements align with your mechanical design. Ensure the supplier provides valid traceability documentation for hermetically sealed components intended for critical applications.
Selection Notes
Select this component when high power dissipation and hermetic sealing are required. The 50W rating suits applications with significant current loads. Verify that the system can accommodate the through-hole TO-3 package dimensions and stud-mounting constraints compared to surface-mount alternatives.
Part Context
This part belongs to the standard Zener diode family produced by Microchip Technology. It serves as a discrete semiconductor solution for voltage control. The TO-204AD package is a legacy form factor often used in military or aerospace-grade electronics requiring high reliability and thermal stability under extreme conditions.
Replacement Considerations
Cross-reference with other manufacturers offering 50V 50W hermetic Zener diodes in TO-3 packages. Verify pinout compatibility and thermal resistance specifications before substitution.
