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.
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.
Applications
- Phase control circuits
- General purpose rectification
- Lighting dimmers
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.
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.
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. These components complement the manufacturer's power SCR lineup and are characterized by glass-passivated junctions for enhanced durability in industrial and consumer electronics.

FAQ
What is the maximum non-repetitive peak forward surge current?
The T107B1 can withstand a peak one-cycle forward surge current of 50 A at 60 Hz.
How does the gate trigger current vary with temperature?
The DC gate trigger current increases as the case temperature decreases. Specific ratios relative to 25 °C are provided in the normalized curves within the datasheet.
What is the typical turn-on time for this device?
The gate-controlled turn-on time depends on the gate trigger current. For a 10 mA gate pulse, the typical turn-on time is approximately 50 µs.
