1N2833B

Overview

The 1N2833B is a single silicon Zener diode manufactured by Microchip Technology, designed for through-hole mounting in the TO-204AD (TO-3) package. It features a nominal Zener voltage of 62 V with a tolerance of ±5% and a maximum power dissipation of 50 W. The device exhibits a maximum Zener impedance of 7 Ohms and a maximum forward voltage of 1.5 V.

Feature Summary

• High power handling capability of 50 watts for robust voltage regulation
• Precision voltage stability with ±5% tolerance at 62 V nominal
• Hermetically sealed construction suitable for demanding environments

Applications

• High-power voltage regulation circuits
• Overvoltage protection systems
• Reference voltage sources in industrial equipment

Procurement Notes

Verify the manufacturer origin, as this component was originally developed by Microsemi Corporation before its acquisition by Microchip Technology. Confirm that the specific suffix 'B' corresponds to the required ±5% tolerance grade. Ensure the procurement channel provides authentic components from authorized distributors to guarantee performance reliability and traceability.

Selection Notes

Select this component when a high-power 50 W Zener diode is required for stable voltage clamping. The TO-204AD package necessitates adequate heatsinking due to significant thermal generation. Consider the 7 Ohm impedance limit for dynamic regulation requirements and ensure the circuit design accommodates the physical dimensions and mounting style of the TO-3 case.

Part Context

This part belongs to the 1N2833 series of 50 Watt Zener Diodes, historically produced by Microsemi Corporation. The series includes variants with different tolerance grades, such as the 1N2833R. The 1N2833B specifically denotes the standard tolerance version within this high-power silicon diode family, now maintained under the Microchip Technology portfolio.

Replacement Considerations

Direct substitutes include other 1N2833 variants with matching electrical specifications. Verify compatibility with alternative manufacturers producing equivalent 50 W TO-204AD Zener diodes rated at 62 V.
