OM4203SA/RA/DA OM4216SA/RA/DA OM4215SA/RA/DA HERMETIC TO-254 SCHOTTKY CENTER-TAP RECTIFIER 25 Amp, 45, 60 and 100 Volt Schottky Rectifier FEATURES • • • • • • • Very Low Forward Voltage Fast Switching Speed Hermetic Metal Package, TO-254 Outline Low Thermal Resistance Isolated Package Ceramic Feedthroughs Available Available Screened To MIL-S-19500, TX, TXV, And S Levels DESCRIPTION This product is specifically designed for use at power switching frequencies in excess of 100 kHz. The product combines two Schottky-barrier diodes in a center-tap configuration in a single package, simplifying installation, reducing heat sink hardware, and the need to obtain matched components. The device is ideally suited for demanding applications where small size and hermetically sealed package is required. Common anode configuration also available.
