Planar passivated high commutation three quadrant triac in a TO220F "full pack" plastic package. This triac is intended for use in motor control circuits where very high blocking voltage can occur. Rated junction temperature (Tj(max) = 150 °C) without the aid of a snubber. It is used in applications where "high junction operating temperature capability" is required.

Features and Benefits
  •   High junction operating temperature capability (Tj(max) = 150 °C)
  •   Full cycle AC conduction
  •   Over-voltage withstand capability to IEC 61000-4-5
  •   Pin compatible with standard triacs
  •   Planar passivated for voltage ruggedness and reliability
  •   Protective self turn-on capability for high energy transients
  •  Triggering in three quadrants only
  •  Very high immunity to IEC 61000-4-4 fast transient
  •  Package meets UL94V0 flammability requirement
  •  Package is RoHS compliant
  •  Package meets UL1557 isolation test requirement rated at 2500V RMS
  •   AC fan, pump and compressor controls
  •   Highly inductive, resistive and safety loads
  •   Large and small appliances (White Goods)
  •   Reversing induction motor controls e.g. vertical axis washing machines
  •   Applications subject to high temperature (Tj(max) = 150 °C)
