MMBD352WT1 Dual Schottky Barrier Diode These devices are designed primarily for UHF mixer applications but are suitable also for use in detector and ultra−fast switching circuits. Features http://onsemi.com • Very Low Capacitance − Less Than 1.0 pF @ Zero Volts • Low Forward Voltage − 0.5 Volts (Typ) @ IF = 10 mA • Pb−Free Package is Available 1 ANODE 3 CATHODE/ANODE 2 CATHODE MAXIMUM RATINGS Rating Continuous Reverse Voltage Symbol Value Unit VR 7.0 VCC Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. 3 SOT−323 (SC−70) CASE 419 STYLE 9 1 2 THERMAL CHARACTERISTICS Characteristic Symbol Max Unit Total Device Dissipation FR− 5 Board (Note 1) TA = 25°C Derate above 25°C PD 200 mW Thermal Resistance, Junction−to−Ambient Total Device Dissipation Alumina Substrate (Note 2) TA = 25°C Derate above 25°C Thermal Resistance, Junction−to−Ambient Junction and Storage Temperature MARKING DIAGRAM 1.6 mW/°C RJA 625 °C/W PD 300 mW 2.4 mW/°C RJA 417 °C/W TJ, Tstg −55 to +150 °C M5 M M5 M = Device Code = Date Code 1.
