Product Description

The BTA12-800CW TRIAC is a high-performance semiconductor device designed for efficient AC load control in industrial and commercial applications. With a 12A current rating and 800V blocking voltage, this triac is ideal for switching high-power AC loads, including motors, heaters, and lighting systems.

Key Features

  • Current Rating: 12A RMS (repetitive on-state current)
  • Voltage Rating: 800V (off-state repetitive peak voltage)
  • High Surge Current Capability: Withstands up to 120A (non-repetitive surge current)
  • Insulated Package: TO-220A fully insulated package for easy mounting without an additional insulator
  • Sensitive Gate: Low trigger current (typically 35mA) for easy drive with microcontrollers or logic circuits
  • Quadrant Operation: Supports triggering in I+, I-, III+, III- modes
  • Snubberless Design: Reduces the need for external snubber circuits in inductive load applications

Typical Applications

  • AC motor speed control
  • Dimmer circuits (lighting control)
  • Heating regulation (industrial heaters, domestic appliances)
  • Solid-state relays (SSRs)
  • Power switches in home automation

BTA12 vs BTB12

The BTA12 is isolated, while the BTB12 is non-isolated. The BTA series is preferred for better insulation and heat dissipation, while the BTB series is used in cost-sensitive, low-isolation applications.

Conclusion

The BTA12-800CW is a versatile and durable triac suitable for medium-power AC switching applications. Its high current and voltage ratings, combined with a fully insulated package, makink it a preferred choice for engineers designing efficient and safe power control systems.
