CS55D PBFREE

Scrs Overview

The CS55D PBFREE is a silicon-controlled rectifier (SCR) manufactured by Central Semiconductor Corp. It features a rated repetitive off-state voltage of 400 V and an RMS on-state current of 800 mA. The device operates in through-hole TO-92-3 packages with a maximum junction temperature range from -40°C to +125°C. Key electrical characteristics include a forward voltage of 1.7 V, a gate trigger voltage of 800 mV, and a holding current maximum of 5 mA. Non-repetitive on-state current capability reaches 10 A.

Scrs Feature Summary

• Provides reliable switching control for AC power applications via gate-triggered conduction
• Designed for robust operation within extended industrial temperature ranges
• Offers high non-repetitive surge current handling capacity

Scrs Applications

• Lighting dimmer circuits
• Motor speed control systems
• Temperature regulation devices

Scrs Procurement Notes

Verify the exact part number suffix against official manufacturer documentation to ensure compliance with RoHS directives and lead-free specifications. Confirm package integrity and pinout alignment during incoming inspection. Cross-reference datasheet revisions to validate updated electrical limits before finalizing procurement orders.

Scrs Selection Notes

Select this component when a low-current SCR is required for through-hole mounting in compact enclosures. Ensure the circuit design accommodates the specified 800 mA RMS limit and 400 V blocking voltage. Evaluate thermal management requirements based on the 1.7 V forward voltage drop at operating currents.

Scrs Part Context

This device belongs to the thyristor family produced by Central Semiconductor Corp. It serves as a discrete semiconductor switch for controlling AC loads. The TO-92-3 packaging allows for standard PCB mounting techniques while maintaining electrical isolation suitable for low-power industrial controls.

Scrs Replacement Considerations

Consult official substitution guides for equivalent SCRs with matching voltage and current ratings. Verify that alternative components support the same TO-92-3 footprint and pin configuration to maintain board compatibility.
