The TPSMB68A from Littelfuse is an automotive-grade unidirectional TVS diode from the TPSMB Series, designed to protect sensitive electronic equipment against transient overvoltage, surge events, and electrostatic discharge. With a peak pulse power capability of 600W, it provides reliable transient protection for automotive, industrial, and power electronics applications.
TPSMB68A features a reverse stand-off voltage of 58.1V and a breakdown voltage range of 64.6V to 71.4V. Its maximum clamping voltage is 92V, with a maximum peak pulse current of 6.6A. The device offers fast response and excellent clamping performance to help protect downstream components from damaging voltage spikes.
Housed in a compact DO-214AA (SMB) surface-mount package, the TPSMB68A is suitable for space-efficient PCB designs and automated assembly. It features a glass-passivated junction, low incremental surge resistance, and high reliability. AEC-Q101 qualification makes it suitable for automotive I/O interfaces, VCC buses, electronic control modules, power supply protection, and other demanding transient voltage suppression applications.
