**Insulated TO-220AC** ## **Features and benefits** - Especially suited as boost diode in continuous mode power factor correctors and hard switching conditions - Designed for high di/dt operation. Hyperfast recovery current to compete with SiC devices. Allows downsizing of mosfet and heatsinks - Internal ceramic insulated devices with equal thermal conditions for both 300 V diodes - Insulation (2500 VRMS) allows placement on same heatsink as mosfet and flexible heatsinking on common or separate heatsink - Static and dynamic equilibrium of internal diodes are warranted by design ## **Description** The TURBOSWITCH “H” is an ultra high performance diode composed of two 300 V dice in series. TURBOSWITCH “H” family drastically cuts losses in the associated MOSFET when run at high dIF/dt. ## **Table 2. Order codes** |**Table 2.**
