ACS102-5T1-TR

Overview

The ACS102-5T1-TR is an AC line switch from the ASD™ family, packaged in SO-8. It features a repetitive peak off-state voltage (VDRM/VRRM) of 500 V and an RMS on-state current (IT(RMS)) of 0.2 A at Tamb = 100 °C. The device includes an integrated high-voltage clamping structure with a typical clamping voltage (VCL) of 600 V to absorb inductive turn-off energy. Gate triggering requires a negative current sourced by the gate pin, with a maximum IGT of 5 mA and VGT of 0.9 V. It operates within a junction temperature range of -30 °C to +125 °C.

Feature Summary

• Integrated overvoltage protection via crowbar technology eliminates the need for external snubbers or varistors.
• Gate level shifter driver separates the digital controller from the main switch, preventing gate kickback stress.
• Common package tab connection supports the parallel connection of multiple switches on a single cooling pad.

Applications

• AC on-off static switching in home appliances such as washing machines, dishwashers, and refrigerators.
• Driving low power high inductive loads including solenoids, valves, relays, dispensers, and micro-motors.
• Control of resistive loads like low power lamp bulbs and door locks.

Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors or verified supply chain channels. Confirm the specific ordering suffix matches the required SO-8 tape and reel packaging configuration. Ensure compliance with RoHS3 standards and check for obsolete status implications regarding long-term availability and lifecycle support before finalizing procurement plans.

Selection Notes

Select this component for applications requiring direct microcontroller interface without external isolation components. The low gate trigger current allows compatibility with standard logic levels. Consider thermal resistance characteristics when designing PCB copper areas under the COM pins to ensure adequate heat dissipation for continuous operation at rated currents.

Part Context

This part belongs to the ACS102 series of AC line switches utilizing Application Specific Discrete (ASD) technology. The series integrates triac structures with overvoltage clamping capabilities. The ACS102-5T1 variant specifically denotes the SO-8 package version, designed for surface mount assembly with common tab connections for thermal management and multi-device integration.

Replacement Considerations

Direct substitutes include other ACS102 variants such as ACS102-5TA for through-hole TO-92 mounting or ACS102-5T1 for tube-packaged SO-8 units. Verify that replacement parts maintain identical electrical ratings, particularly the 500 V blocking voltage and 0.2 A current handling, to ensure circuit compatibility.
