The VS-50TPS12L-M3 from Vishay Intertechnology is a new 50A phase-control thyristor in a TO-247 package with long leads. It is suitable for implementing line- rectification, soft-start motor-control and temperature-control functions.

Vishay’s intention in introducing the VS-50TPS12L-M3 is to provide a new medium-power option in a three-lead through- hole package for power-switching applications. The long 20mm leads provide flexibility in PCB mounting.

The thyristor’s glass passivation technology provides reliable operation up to a maximum junction temperature of 150°C. In addition, the device’s high dV/dT rating of 1,000V/μs provides a high level of immunity to EMI. Its peak repetitive reverse voltage is rated at 1,200V.

FEATURES

  • 1.1V on-state voltage
  • 630A peak surge current
  • 150A/μs maximum rate of turned-on
    current rise
  • 350mA maximum latching current

APPLICATIONS

  • Uninterruptible power supplies
  • Welding equipment
  • Power converters
  • Industrial battery chargers
  • Solid-state relays
