Product Description

The BTA08-800C is a 8A, 800V triac designed for AC switching applications. It is widely used in motor control, lighting dimmers, heating systems, and other power regulation circuits.Its insulated tab package ensures electrical isolation and safety in compact designs.

Main Technical Parameters

  • Voltage level: 800V (VDRM)
  • Current capacity: 8A (IT (RMS))
  • Trigger current: typical value 25mA (IGT)
  • Package: TO-220AB insulation package
  • Operating temperature range: -40°C to 125°C

Structure and Working Principle

1.Internal Structure

BTA08-800C adopts NPNPN five-layer structure with three electrodes:

  • Main terminal 1 (MT1): usually connected to the load side
  • Main terminal 2 (MT2): usually connected to the power supply side
  • Gate (G): control electrode, used to trigger the device to turn on

2.Working Principle

As a bidirectional thyristor, BTA08-800C has the following characteristics:

  • It can be triggered to conduct in both the positive and negative half cycles of the AC power
  • Once triggered to conduct, it will remain on even if the gate signal is removed
  • It will only turn off when the current is lower than the holding current (IH)

Features and Advantages

  • Direct interfacing to logic level ICs
  • Direct interfacing to low power gate drive circuits
  • High blocking voltage capability
  • Planar passivated for voltage ruggedness and reliability
  • Triggering in all four quadrant

Typical Applcations

1.Household Appliances:

  • Temperature control of rice cookers and electric kettles
  • Water level control of washing machines
  • Fan speed control of air conditioners

2.Industrial Control:

  • Small motor control
  • Power regulation of heating elements
  • Lighting control systems

3.Other Applications:

  • Solid-state relays
  • AC power switches
  • Reactive power compensation devices

When selecting, the following factors should be considered to determine whether to use BTA08-800C:

  • Operating voltage and current: whether it is within the range of 800V withstand voltage and 8A on-state.
  • Insulation requirements: The BTA series provides an insulating backplane, which is suitable for scenarios with electrical safety requirements.
  • Price and availability: BTA08-800C has a stable market supply and a moderate price. It is a cost-effective general-purpose bidirectional thyristor.
