1N2824B

Overview

The 1N2824B is a 50 W Zener diode manufactured by Microchip Technology, housed in the TO-204AD (TO-3) through-hole package. It features a nominal Zener voltage of 33 V with a tolerance of ±5%. The device operates within a junction temperature range of -65 °C to +175 °C and supports a storage temperature up to 200 °C. Standard polarity configuration places the anode at the case, with reverse polarity options available.

Feature Summary

• High power dissipation capability of 50 W for robust voltage regulation
• Standard anode-to-case polarity configuration with reverse polarity availability
• Wide operating temperature range suitable for demanding environments

Applications

• High-power voltage regulation circuits
• Military and aerospace electronic systems
• Industrial equipment requiring stable reference voltages

Procurement Notes

Verify the specific polarity requirement, as standard units feature an anode-to-case connection while reverse polarity variants exist. Confirm RoHS compliance status if required by project specifications. Ensure thermal management design accounts for the 50 W power dissipation rating at the specified case temperature limit. Validate that the TO-204AD package dimensions match the target PCB or chassis mounting constraints.

Selection Notes

Select this component when high power handling is necessary compared to lower-wattage Zener alternatives. The TO-3 package provides superior thermal performance for continuous high-current applications. Consider the anode-to-case electrical connection during circuit layout, as it affects grounding strategies. Verify that the 33 V breakdown voltage aligns precisely with the system's regulation requirements.

Part Context

This part belongs to the 1N2824 series of 50 Watt Zener diodes produced by Microchip Technology. The series includes various voltage ratings within the same mechanical and thermal form factor. These components are designed for applications requiring reliable voltage clamping under significant power loads, distinguishing them from low-power signal diodes.

Replacement Considerations

The 1N2824 is a compatible variant within the same series offering identical 50 W power dissipation and TO-204AD packaging. Verify voltage tolerance and polarity configurations before substitution to ensure electrical compatibility.
