SMCJ90A is a unidirectional transient voltage suppressor diode designed for surge and ESD protection in portable communications, computing, and video equipment. The device features a breakdown voltage of 100 V and a working voltage of 111 V, with a maximum clamp voltage of 95 V at the specified peak current. It is housed in a compact SMC (DO-214AB) surface mount package and offers fast response times of less than 1.0 picosecond, making it ideal for protecting sensitive circuits from transient overvoltages. The SMCJ90A is RoHS compliant and suitable for applications requiring IEC 61000-4-2 ESD, IEC 61000-4-4 EFT, and IEC 61000-4-5 Surge protection.
