2N2326S

Scrs Overview

The 2N2326S is a silicon controlled rectifier (SCR) manufactured by Microchip Technology, designed for military applications under MIL-PRF-19500/276 qualification. It features a sensitive gate structure housed in a TO-5 metal can package with through-hole mounting. Key electrical parameters include a maximum repetitive peak off-state voltage of 200 V and a maximum average on-state current of 220 mA. The device requires a maximum gate trigger voltage of 600 mV and a maximum gate trigger current of 20 µA to initiate conduction. It maintains a holding current of up to 2 mA and operates within a junction temperature range of -65°C to 125°C.

Scrs Feature Summary

• Qualified for military standards under MIL-PRF-19500/276 specifications
• Sensitive gate architecture enabling low-power triggering
• Robust TO-5 metal can construction for environmental durability

Scrs Applications

• Military-grade switching circuits requiring high reliability
• Cryogenic electronic systems operating at low temperatures
• High-reliability power control modules

Scrs Procurement Notes

Verify the specific suffix 'S' against official Microchip documentation to confirm hermetic sealing status, as standard 2N2326A data may not explicitly define the S variant's physical seal integrity. Confirm that the component meets the exact MIL-PRF-19500/276 requirements for your application. Ensure compatibility with existing TO-5 footprints and validate thermal management strategies for the specified temperature range before integration.

Scrs Selection Notes

Select this component when military qualification and wide temperature operation are mandatory. The sensitive gate characteristic simplifies drive circuit design by minimizing required trigger power. Compare the 200 V blocking capability and 220 mA current rating against load requirements. Consider the TO-5 package constraints for board space and thermal dissipation compared to surface-mount alternatives.

Scrs Part Context

The 2N2326S belongs to the 2N2323–2N2329A series of silicon controlled rectifiers produced by Microchip Technology. This family is specifically engineered for rugged environments, adhering to strict military performance standards. The series shares common architectural traits but varies in specific voltage and current ratings, positioning these devices for specialized aerospace and defense electronics where standard commercial components would fail.

Scrs Replacement Considerations

Publicly confirmed substitute part numbers for the 2N2326S are not available in the provided reference material. Verify cross-compatibility with other MIL-PRF-19500/276 qualified SCRs from Microchip or other authorized manufacturers only after confirming identical pinout, voltage ratings, and package dimensions.
