## **Features** - Clamping voltage characteristics defined at 25 °C, 85 °C and 125 °C - Stand-off voltage range: from 85 V to 188 V - Low leakage current: 0.2 µA at 25 °C - Maximum operating junction temperatures: - SMB and SMC: 150 °C - DO-15 and DO-201: 175°C ## **Complies with the following standards:** - IEC 61000-4-2 level 4 - ±15 kV (air discharge) - ±8 kV (contact discharge) - MIL-STD-883, method 3015, class 3B: - 25 kV HBM (human body model) - MIL-STD-750, method 2026 solderability - EIA STD RS-481 and IEC 60286-3 packing (surface mount packages) ## **Applications** - MOSFET protection - IGBT protection - Auxiliary power supply ## **Description** The STRVSX series is a TVS family created to provide simple and effective solutions for designers working on circuits that require protection from repetitive overvoltage. The STRVSX series is highly reliable and suits applications where the surge frequency makes the protected device temperature increase, for example, MOSFET protection in fly back configuration. Additional support for designers using these devices is available in the STMicroelectronics application note AN4209: “Design methodology for repetitive voltage suppressors (RVS) in repetitive mode: STRVS”. **Table 1.
