Scrs datasheet and documents for TCR22-8RP

TCR22-8RP

Scrs Overview

The TCR22-8RP is a silicon-controlled rectifier (SCR) from the Littelfuse TCR22-X series, designed for sensitive gate triggering in low-current switching applications. It features a rated repetitive off-state voltage (VDRM) of 400 V and an on-state RMS current (IT(RMS)) of 1 A. The device requires a maximum gate trigger current (IGT) of 200 µA and has a forward voltage drop (VF) of 1.5 V. Operating within a temperature range of -40 °C to +125 °C, it utilizes a through-hole installation style with a glass-passivated junction for durability.

Scrs Feature Summary

Sensitive gate architecture enabling direct interfacing with microprocessors using minimal gate current.
Glass-passivated junction construction ensures long-term durability and reliability under varying conditions.
Fast turn-off capabilities reduce the risk of commutation failure in precise switching circuits.

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 package type and lead configuration. Ensure compatibility with existing PCB footprints and thermal management requirements before integration. Cross-reference the Mouser number 576-tcr22-6 for accurate sourcing channels and distributor availability.

Scrs Selection Notes

Select this component for applications requiring low gate drive power and high voltage blocking capability up to 400 V. The 1 A RMS rating suits moderate current loads, while the sensitive gate specification allows for efficient control logic integration. Confirm that the through-hole package aligns with assembly processes and mechanical constraints.

Scrs Part Context

This SCR belongs to the TCR22-X series, which offers a broad range of solutions for efficient switching in low-current circuits. The series includes variants with different ampere ratings and surge capabilities, optimized for demanding electronic controls and ground fault circuit interrupter solenoids.

Scrs Replacement Considerations

Check for exact pin-compatible substitutes within the TCR22-X family or other Littelfuse SCRs with matching 400 V VDRM and 1 A IT(RMS) ratings. Verify that alternative parts maintain the same sensitive gate characteristics and through-hole packaging to ensure seamless replacement without circuit redesign.
