SMLJ70A is a surface mount transient voltage suppressor (TVS) diode designed for surge and ESD protection applications. It features a peak pulse power dissipation of 3000 watts at 1 ms pulse width and a working peak reverse voltage of 70 V. The device operates over a temperature range of -55°C to +150°C and is housed in a compact SMC (DO-214AB) package. With typical fast response times of less than 1.0 ns for unidirectional devices, it provides effective protection for portable communications, computing, and video equipment against transient voltage events.
