The SMCJ45A is an ultra-fast, transient voltage suppression device (TVS) manufactured by TWGMC an d compliant with RoHS standards. This component is typically used for overvoltage and ESD protection in applications including cell phones, PDAs, computers, home appliances, and telecom equipment. The SMCJ45A offers low leakage current, fast response time, and a clamping voltage that is ideal for harsh environments. It also supports reverse-bias avalanche capability for protecting circuits against transients up to 24 V. Other key features include a 5 kV ESD level, high surge capability over a wide operating temperature range, and excellent clamping grade for low inductance applications.
