LSIC2SD12A1 RoHS Pb Description This series of silicon carbide (SiC) Schottky diodes has negligible reverse recovery current, high surge capability, and a maximum operating junction temperature of 175 C. These diodes series are ideal for applications where improvements in efficiency, reliability, and thermal management are desired. Features Positive temperature coefficient for safe operation and ease of paralleling 175 C maximum operating junction temperature Excellent surge capability Extremely fast, temperature-independent switching behavior Dramatically reduced switching losses compared to Si bipolar diodes Circuit Diagram TO-22-2L Applications Case Case Boost diodes in PFC or DC/DC stages Switch-mode power supplies Solar inverters Industrial motor drives EV charging stations 1 2 Uninterruptible power supplies 1 2 Environmental Littelfuse RoHS logo = RoHS conform Littelfuse HF logo = Halogen Free Littelfuse PB-free logo = PB--free lead plating RoHS Pb Maximum Ratings Characteristics Symbol Conditions Value Unit Repetitive Peak Reverse Voltage RM - 12 V DC Blocking Voltage T j = 25 C 12 V 28 Continuous Forward Current I F A = 125 C 15 T = 25 C C = 151 C 1 Non-Repetitive Forward Surge Current I FSM = 25 C, T P = 1 ms, Half sine pulse 8 A T Power Dissipation P C = 25 C 136 Tot = 11 C 59 W Operating Junction Temperature - -55 to 175 C Storage Temperature T STG - -55 to 15 C Soldering Temperature T sold - 26 C
