This document is a technical datasheet for the Microsemi FST19235, FST19240, and FST19245 Schottky Powermod series. These components are Schottky barrier rectifiers designed with guard ring protection and an electrically isolated baseplate made of nickel-plated copper.
The datasheet provides detailed electrical characteristics, including a working peak repetitive reverse voltage range from 35V to 45V, average forward currents up to 200 Amps per package, and maximum surge currents of 1500 Amps. It also includes thermal specifications such as junction-to-case thermal resistance and operating temperature ranges from -55°C to 150°C.
| Working Peak Repetitive Reverse Voltage (VRRM) | 35 to 45 Volts |
|---|---|
| Average Forward Current per pkg. (IF(AV)) | 200 Amps |
| Maximum Surge Current per leg (IFSM) | 1500 Amps |
| Max. Peak Forward Voltage per leg (VFM) | 0.40 Volts |
| Operating junction temp range (Tj) | -55°C to 150°C |
| Max thermal resistance per leg (Rjc) | 0.7°C/W |
The typical junction capacitance per leg (Cy) is 5500 pF.
The baseplate is made of nickel plated copper and is electrically isolated.
