The Littelfuse 1KSMB47CA is a bidirectional Zener TVS diode designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. It offers a reverse standoff voltage of 40.2V and a clamping voltage of 64.8V, with a peak pulse power rating of 1000W (10/1000μs waveform). The device features a fast response time of less than 1.0ps and meets IEC 61000-4-2 ESD protection standards (Air: 30kV, Contact: 30kV).
This TVS diode is housed in a DO-214AA (SMB) surface mount package, suitable for automated assembly and space-constrained designs. The plastic package is rated UL94 V-0 for flammability and is halogen-free with matte tin lead-free plating (Pb-free E3). The device is designed for general purpose applications including I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics.
The 1KSMB series bridges the gap between 600W and 1.5kW surge ratings, offering a high surge rating in a compact package. The device is rated for operating junction temperatures from -55°C to 150°C (with datasheet reference to -65°C to 150°C).
