2N6565RP

Scrs Overview

The Littelfuse 2N6565RP is a sensitive silicon-controlled rectifier (SCR) designed for low-current switching applications. It features a 400 V repetitive peak off-state voltage and an RMS on-state current rating of 0.8 A. The device utilizes a TO-92 through-hole package with glass-passivated junctions for reliability. Key electrical parameters include a maximum gate trigger current of 200 µA, a holding current of 5 mA, and a non-repetitive surge current capability of 20 A. It operates within a temperature range of -40 °C to +110 °C.

Scrs Feature Summary

• Sensitive gate control allows direct interfacing with microprocessors using minimal gate current.
• Glass-passivated junctions provide a rugged barrier against contamination for long-term stability.
• TO-92 package offers electrically isolated case or tab options for convenient assembly.

Scrs Applications

• Strobe light triggering circuits
• Fluid level sensors
• Capacitive-discharge ignition systems

Scrs Procurement Notes

Verify the specific suffix 'RP' against the manufacturer's official documentation to confirm packaging details such as tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for the intended application. Cross-reference the part number with the latest Littelfuse datasheets to confirm availability and any potential obsolescence notices before finalizing procurement plans.

Scrs Selection Notes

Select this component when a low gate sensitivity SCR is required for precise switching in low-current circuits. The 400 V rating suits applications requiring moderate blocking voltage. Consider the TO-92 package constraints for thermal management and PCB space. Verify that the 200 µA gate trigger current aligns with the driving circuit's output capabilities to ensure reliable turn-on under all operating conditions.

Scrs Part Context

The 2N6565RP belongs to the Teccor line of sensitive SCRs manufactured by Littelfuse. This series complements power SCRs by offering ratings from 0.8 A to 10 A with high gate sensitivities. The 2N6565 specifically falls into the 0.8 A category with a 400 V blocking voltage, conforming to JEDEC registered data standards for thyristors.

Scrs Replacement Considerations

Direct replacements within the same family include the 2N5064 (200 V) and other EC103xx variants with matching voltage and current ratings. Verify pinout compatibility and thermal resistance characteristics when substituting with devices from different manufacturers or package types.

Scrs FAQ
