T107B1

Scrs Overview

The Littelfuse T107B1 is a half-wave unidirectional, gate-controlled silicon controlled rectifier (SCR) with a 4 A RMS on-state current rating. It features a repetitive peak off-state voltage of 200 V and a maximum DC gate trigger current of 500 µA. The device utilizes a TO-202 package with an anode-connected case. Key electrical parameters include a peak on-state voltage of 2.5 V, a holding current of 8 mA, and a non-repetitive peak surge current capability of 50 A for one cycle at 60 Hz.

Scrs Feature Summary

Glass-passivated junctions provide long-term device reliability and parameter stability against contamination.
High surge capability supports demanding transient conditions in power switching applications.
Sensitive gate design allows triggering with low gate currents, facilitating simple control circuitry.

Scrs Procurement Notes

Verify the specific ordering suffix to confirm the exact lead frame configuration and packaging type required for your assembly process. Confirm RoHS compliance status and check for any custom design variations by consulting the manufacturer directly if standard configurations do not meet mechanical constraints.

Scrs Selection Notes

Select this component when a 4 A continuous current rating and 200 V blocking voltage are required in a TO-202 package. Ensure the application's thermal management aligns with the specified thermal resistance values. Verify that the gate drive circuit can supply sufficient current to exceed the 500 µA trigger threshold under all operating temperatures.

Scrs Part Context

This device belongs to the Teccor line of sensitive SCRs manufactured by Littelfuse. The product family covers ratings from 0.8 A to 10 A with voltages up to 600 V.
