Product Description

The bta41-800B is a high-performance 40A,800V triac designed for AC load control in industrial,commercial,and consumer applications.Its electrically isolated TO-220A package ensures safe and easy heatsink mounting,critical for thermal management in high-current applications.Whether used in motor controls, solid-state relays,lighting dimmers,or power tools,the BTA41-800B delivers high noise immunity, excellent dV/dt tolerance (1000V/µs),and low conduction losses,making it a preferred choice for designers seeking efficiency and durability in AC switching solutions.

Technical Specifications

  • Repetitive Off-State Voltage (VDRM): 600V
  • Gate Trigger Current (IGT): ≤50mA
  • On-State Voltage Drop (VTM): 1.55V
  • Critical Rise Rate (dI/dt): 50A/µs

Key Features

  • High Current Capacity: 40A RMS current rating, ideal for demanding AC load control in industrial and commercial applications.
  • Voltage Resilience: 800V blocking voltage ensures reliable performance in high-voltage circuits.
  • Isolated Tab (TO-220A): Electrically isolated mounting base simplifies heatsink installation and enhances safety.
  • Snubberless Design: Built-in high dV/dt tolerance (up to 1000V/µs) reduces the need for external snubber circuits.
  • Logic-Level Gate Triggering: Low gate current (IGT ≤ 50mA) enables compatibility with microcontrollers and logic circuits.

Applications

  • Industrial motor controls, HVAC systems
  • Lighting dimmers and AC power switches
  • Solid-state relays (SSRs) and contactors
  • Home appliances and power tools
