The PKC-136 is a product that protects the MOSFET in flyback power supplies. Its features are accurate voltage clamping regardless of load, reduced current loop, reduced EMI emission, high integration, fast assembly and reduced losses in standby mode.
The document describes the STMicroelectronics PKC-136, an integrated device featuring a TRANSIL and a blocking diode within a single DO-15 package. It is designed to protect MOSFETs in flyback power supply applications by providing accurate voltage clamping regardless of load conditions.
Key characteristics include a peak reverse voltage (Vrrm) of 700 Vdc, a maximum power dissipation of 1.5 W at T°lead = 90°C, and operation within a storage temperature range of -40 to +150 °C. The datasheet provides detailed electrical characteristics for both the TRANSIL and diode sections, along with thermal resistance data and mechanical dimensions.
