SMBJ15CA Diode Bidirectional TVS Diode SMD 15V SMBJ15 Diode SMBJ15CA

The SMBJ15CA is a 15V, 600W surface-mount bidirectional transient voltage suppression (TVS) diode manufactured by Littelfuse, Inc. for protecting sensitive electronic components from high-voltage transients and electrostatic discharge (ESD) events. Housed in a compact DO-214AA (SMB) molded plastic package, this discrete component features a bidirectional configuration designed to clamp overvoltage surges in both polarities while optimizing board space. It operates with a reverse stand-off voltage of 15V and exhibits a breakdown voltage range between 16.7V and 18.5V while carrying the package top-side marking code "BM". Engineered with an ultra-fast response time, low incremental surge resistance, and excellent clamping capability, this robust device delivers reliable protection across an operating temperature range from minus 65 to plus 150 degrees Celsius.
