January 2003 Extremely Fast Recovery for RF & MHz Switching Applications GaAs Schottky Diode s • Advantage Extremely Fast Reverse Recovery Times, Typically <15nS • Much lower forward Voltage than Silicon Carbide • Isolated, low inductance, surface mount, high power package GS150TI25110 GS150TC25110 GS150TA25110 GS150TI25150 GS150TC25150 GS150TA25150 GS150TI25104 GS150TC25104 GS150TA25104 GS150TI25120 GS150TC25120 GS150TA25120 *Three configuration options available: TI - Triple Independent, TC - Triple Common Cathode, TA - Triple Common Anode Example: GS150TI25104 - The Triple Independent version. Description This new line of High Speed GaAs Schottky Diodes provide extremely fast recovery times, outperforming both Ultrafast and Silicon Carbide technologies. The recovery times and low junction capacitances combined with their inherently low forward voltages make this new product family ideal for High Frequency Converters, Resonant Converters and Switch Mode Power Supplies operating from the KHz-MHz range. The GaAs devices are packaged in the low inductance, low profile, electrically isolated, surface mount DE-150 package. The matched thermal coefficient of expansion between the aluminum nitride substrate and the GaAs Diode result in improved reliability and power cycling performance. The GaAs Schottky products have an added advantage when used in conjunction with the DE Series Switch Mode & RF Mosfets. Both products utilize the same package profiles resulting in a convenient single plane to heat sink. Each device contains three diodes, with three different configuration options; Triple *GS150T_25104 250 V 4 A 9pF 1.5V 9 W 16.3 C/W *GS150T_25110 250 V 10 A 18pF 1.5V 15 W 9.6 C/W *GS150T_25120 250 V 20 A 36pF 1.5V 20 W 7.2 C/W *GS150T_25150 250 V 50 A TBD TBD TBD TBD
