The P6SMB91CA is a bidirectional TVS diode from Littelfuse, designed to protect sensitive electronic equipment from voltage transients. It features a reverse standoff voltage of 77.8V and a maximum clamping voltage of 125V at 4.9A peak pulse current. With a peak pulse power dissipation of 600W (10/1000μs waveform), it provides robust protection for general purpose applications.
Housed in a DO-214AA (SMB) surface mount package, it offers optimized footprint for minimal PCB space impact. The device operates over a temperature range of -55°C to 150°C junction temperature.
Fast response time typically less than 1.0ps ensures rapid clamping of transients. Low leakage current less than 1μA at standoff voltage. Ideal for protecting I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics.
