EC103B1RP

Scrs Overview

The Littelfuse EC103B1RP is a sensitive Silicon Controlled Rectifier (SCR) from the Teccor line, designed as a half-wave unidirectional gate-controlled rectifier. It features a non-isolated TO-92 package with three leads and glass-passivated junctions for parameter stability. The device supports an on-state current of 0.8 A RMS and 0.51 A average at 25 °C, with a repetitive peak off-state voltage rating of 200 V. Gate trigger current is specified at a maximum of 12 µA, enabling high sensitivity for low-power control applications.

Scrs Feature Summary

• Glass-passivated junction construction ensures long-term reliability and protection against contamination.
• High gate sensitivity allows triggering with minimal control current.
• Electrically isolated case design in compatible packages facilitates low-cost assembly.

Scrs Applications

• Low-power AC switching circuits
• Battery charger control logic
• Lighting dimmer circuits

Scrs Procurement Notes

Verify the specific ordering suffix to confirm the tape-and-reel packaging configuration, as standard bulk availability may differ. Confirm that the component matches the required JEDEC registration data if strict compliance is necessary for the design. Ensure the supplier provides documentation confirming the RoHS compliant status of the delivered units.

Scrs Selection Notes

Select this component when a low gate trigger current is required for efficient control circuitry. The 200 V voltage rating limits suitability to low-voltage AC systems. Consider thermal derating curves for operation above 25 °C case temperature. Verify that the TO-92 package dimensions fit the target PCB layout constraints.

Scrs Part Context

This part belongs to the EC Series of sensitive SCRs manufactured by Littelfuse under the Teccor brand. The series includes variants with different voltage ratings and gate sensitivities. The EC103B1RP specifically denotes the 200 V blocking voltage and 12 µA gate sensitivity within the 0.8 A current class.
