The 1.5SMC51A is a 1500W peak pulse power TVS diode from Littelfuse, designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. It features a reverse standoff voltage of 43.6V and a maximum clamping voltage of 70.1V at 21.7A peak pulse current (10/1000μs waveform).
This unidirectional device is housed in a DO-214AB (SMC) surface mount package, suitable for automated assembly. It offers excellent clamping capability and low incremental surge resistance. The operating temperature range is -65°C to 150°C, with storage from -65°C to 175°C.
The 1.5SMC51A is ideal for protecting I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronic applications. It is RoHS3 compliant, halogen free, and has a flammability rating of V-0.
