SMF33CA Diode SMD SOD-123F Bidirectional TVS Diode 33CA 33V HM SMF33CA

The SMF33CA is a 33V, 200W 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, low-profile SOD-123FL (SMF) 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 33V and exhibits a minimum breakdown voltage of 36.7V while carrying the package top-side marking code "HM". 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.
