Techno Block 2 in 1 Fast Recovery Diode Module

We achieve excellent long-term reliability, high-temperature operation, size and weight reduction by combining our high-speed diode chip with our unique "Techno Block" Package

Unique package combining the transfer mold method with a structure in which a metal and a chip are sandwiched by soldering.
Achieves long-term reliability and downsize by not using wire bonding technology for connection.
Techno Block is a trademark of Sansha Electric MFG. Co., Ltd.

Features

By adopting "Techno Block" package,

  • the power cycle capability is 5 times better than conventional one (@△Tj=100℃)
  • the device is smaller, lighter, and can operate at high temperature (Tj=150℃)

Applications

  • Welding machines
  • Plasma cutting machines
  • Plating equipment

Maximum Ratings

Tj = 25℃ unless otherwise specified
