The SA45A is a 500W transient voltage suppression (TVS) diode from Littelfuse's SA series, designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events.
Key electrical specifications include a reverse standoff voltage of 45V, a breakdown voltage of 72.7V, and a clamping voltage of 72.7V. It can handle a peak pulse current of 7A under a 10/1000μs waveform and features a fast response time of typically less than 1.0ps. The device is unidirectional with a single channel and is not intended for power line protection.
The SA45A is housed in a DO-204AC (DO-15) axial leaded package and is designed for through-hole mounting. It operates over a junction temperature range of -55°C to 175°C and has a steady state power dissipation of 3.0W on an infinite heat sink. The part is halogen free, RoHS compliant, and has a Pb-free E3 terminal finish.
