Key Features

  • Triple-element AC switch with common main terminal 1 configuration, enabling compact 3-channel switching in a single 20-pin SOIC footprint
  • Integrated built-in clamping structure and gate-level shifter driver enhancing transient robustness and simplifying drive circuit design
  • High-reliability design with plastic/epoxy rectangular SOIC-20 package suitable for industrial and consumer AC load-switching applications

Applications

The ACS302-5T3-TR is designed for AC load switching in home appliances, industrial control panels, and consumer electronics where multiple independent AC channels must be controlled from a low-voltage logic interface. Its integrated gate shifter driver allows direct interfacing with microcontroller outputs without additional discrete drive components for each switch element. The 3-element common terminal architecture makes it especially useful in multi-zone heating, motor starting, and relay replacement circuits where board space is at a premium.

Frequently Asked Questions

How many independent AC switching channels does the ACS302-5T3-TR provide in a single package?

The ACS302-5T3-TR integrates 3 switching elements in a single 20-pin SOIC package, all sharing a common main terminal 1. This allows control of 3 separate AC loads simultaneously from one IC, reducing BOM count compared to using 3 discrete triacs, and the 20-pin footprint keeps PCB area requirements low.

What protection features does the ACS302-5T3-TR include to handle AC line transients?

The ACS302-5T3-TR incorporates a built-in clamping structure on each switching element to absorb voltage transients that exceed normal AC line levels, protecting the gate and main terminals from surge damage. This internal clamp reduces the need for external snubber networks, simplifying board design in mains-connected AC switching applications.

Can the ACS302-5T3-TR be driven directly from a 3.3 V or 5 V microcontroller GPIO to control AC loads?

Yes, the ACS302-5T3-TR includes an integrated gate-level shifter driver that translates low-voltage logic control signals into the gate drive needed to trigger the AC switch elements. This enables direct interfacing from 3.3 V or 5 V microcontroller outputs without discrete optocouplers or gate driver ICs per channel, simplifying multi-channel AC control designs.

What package does the ACS302-5T3-TR use, and how does the -TR suffix affect ordering?

The ACS302-5T3-TR uses a 20-pin small outline SOIC package (JESD-30 code R-PDSO-G20) with a plastic/epoxy body and rectangular profile. The -TR suffix denotes tape-and-reel packaging, which delivers parts on a continuous 1000-piece or 2500-piece reel for high-volume automated pick-and-place SMT assembly lines.
