Definition of BT139-600B

The BT139-600B is a medium power bidirectional thyristor (thyristor) in a standard TO-220C package, designed for general purpose AC switching and phase control applications. This device has a blocking voltage of 600V and an effective current carrying capacity of up to 16A, making it an ideal choice for applications such as home appliances, industrial control and lighting dimming.

Main Characteristic Parameters

  • Package type: TO-220C (insulated type)
  • Blocking voltage (VDRM): 600V
  • Repetitive off-state voltage (VRRM): 600V
  • On-state effective value current (IT(RMS)): 16A
  • On-state non-repetitive surge current (ITSM): 140A (a 10ms sine half wave)
  • Gate trigger current (IGT): ≤50mA
  • Holding current (IH): ≤60mA
  • Junction temperature range (Tj): -40°C to +125°C

TO-220C Package

TO-220C is a variant package of the TO-220 series. The letter "C" stands for "Completely insulated" or "with insulating pad". Compared with the standard TO-220 package, TO-220C has the following features:

  • Insulation characteristics: The back of the package has an insulating layer and can be directly mounted on the heat sink without an additional insulating pad
  • Mechanical structure: The plastic body and the metal heat sink are isolated by a high thermal conductivity insulating material
  • Pin arrangement: Standard three-pin configuration (MT1, MT2, G)
  • Thermal resistance: The typical junction-to-case thermal resistance (Rthj-c) is 1.5°C/W

Features and Advantages

  • High current 16 A RMS current Triac
  • Low thermal resistance
  • High commutation or very high commutation capability
  • RoHS (2002/95/EC) compliant packages
  • UL-94, V0 flammability package resin compliance

Typical Applications

  • General purpose motor control circuits
  • Phase control operations in light dimmers and motor speed controllers
  • Home appliances

Summary

The BT139-600B in TO-220C package will continue to maintain its important position in medium-power applications due to its good cost-effectiveness and reliability, especially in situations where insulated installation and moderate heat dissipation requirements are required.
