ACS102-6TA

Overview

The ACS102-6TA is a transient protected AC switch from the ACS line, manufactured by STMicroelectronics. It integrates an overvoltage crowbar structure and a gate level shifter driver to separate digital controllers from the main switch. Triggered by negative gate current, it controls loads up to 0.2 A RMS with a 600 V blocking voltage. Key electrical parameters include a maximum gate trigger current of 5 mA, a holding current of 20 mA, and a static dV/dt immunity exceeding 300 V/µs. The device operates within a junction temperature range of -30°C to +125°C and is housed in a TO-92 package.

Feature Summary

• Overvoltage protection via integrated crowbar technology absorbs surge energy without external components
• High noise immunity against static dV/dt and IEC 61000-4-4 burst transients
• Gate level shifter driver isolates the digital controller from the high-voltage main switch
• Common package tab connection supports parallel mounting of multiple switches on a single cooling pad

Applications

• AC ON/OFF static switching in household appliances
• Industrial control systems requiring low power load driving
• Control of high inductive or resistive loads such as relays, valves, solenoids, door locks, and micro-motors

Procurement Notes

Verify the specific ordering suffix to confirm the packaging format. The standard 'A' suffix indicates bulk packing in TO-92 packages, while '-TR' denotes tape and reel configuration. Confirm that the component meets RoHS compliance standards for your manufacturing process. Ensure the selected variant matches the required thermal dissipation capabilities for the intended ambient operating conditions.

Selection Notes

Select this component when designing circuits that require direct interfacing with microcontrollers without additional snubber networks. The device is suitable for applications needing robust protection against AC line transients up to 2 kV. Consider the 0.2 A RMS current limit and the 600 V rating when sizing for specific load requirements. Verify compatibility with negative gate triggering logic levels used in the system controller.

Part Context

The ACS102-6TA belongs to the ACS family built on ASD (Application Specific Devices) technology. This series is designed to replace standard triacs by reducing component count by up to 80%. The integration of overvoltage protection allows equipment to meet IEC 61000-4-5 standards directly. The common tab design facilitates efficient thermal management in dense PCB layouts.

Replacement Considerations

ACS102-6T1 serves as the SO-8 package equivalent within the same electrical specification family.
