Scrs datasheet and documents for TCR22-4RP

TCR22-4RP

Scrs Overview

The Littelfuse TCR22-4RP is a sensitive gate silicon-controlled rectifier (SCR) from the Teccor line, designed for low-current switching applications. It features a TO-202 package with a rated average on-state current of 1.5 A and a repetitive peak off-state voltage of 200 V. The device has a maximum DC gate trigger current of 200 µA and a peak on-state voltage of 1.5 V. It supports a peak one-cycle forward surge current of 20 A at 60 Hz. The operating junction temperature range spans from -40 °C to +125 °C.

Scrs Feature Summary

Sensitive gate architecture enabling direct interfacing with microprocessors via low gate trigger currents.
Glass-passivated junctions providing durability against junction contamination and ensuring parameter stability.
Electrically isolated TO-202 package allowing safe mounting to heatsinks without external insulators.

Scrs Applications

Strobe light control circuits
Fluid level sensing systems
Capacitive-discharge ignition systems

Scrs Procurement Notes

Verify the specific suffix RP against official Littelfuse documentation to confirm lead form or packaging variations. Ensure the selected component matches the required voltage and current ratings for the target circuit design before procurement.

Scrs Selection Notes

Select this component for applications requiring precise phase control with minimal gate drive power. Consider the thermal resistance characteristics and derating curves when designing for high ambient temperatures or continuous conduction modes.

Scrs Part Context

This part belongs to the Teccor Sensitive SCRs series, which complements Littelfuse's power SCR lineup. The series offers various packages including TO-92, TO-202, and surface mount options, catering to diverse assembly needs while maintaining consistent electrical performance standards.

Scrs Replacement Considerations

Direct substitutes include other TCR22 series variants with different voltage ratings such as TCR22-6 or TCR22-8, provided the lower voltage rating does not compromise circuit safety. Cross-reference with standard JEDEC registered devices like 2N5064 if pin compatibility and similar electrical parameters are required.

Scrs FAQ

What is the maximum gate trigger current for the TCR22-4RP?

The maximum DC gate trigger current (IGT) is specified as 200 µA at a case temperature of 25 °C.

Does the TCR22-4RP offer electrical isolation?

Yes, the TO-202 package provides electrical isolation between the leads and the mounting tab, withstanding a minimum high potential test of 2500 V ac rms.
