Product Description

The 1SMA5940B, a member of the SMAJ TVS diode series, is a SMAJ5940B avalanche diode engineered for transient voltage suppression in industrial power systems and communication equipment. This unidirectional diode features a 58.1V reverse standoff voltage with a breakdown range of 64.4-71.2V, capable of handling 600W peak pulse power. Its compact SMA package operates across -55°C to +150°C, supporting direct connection to DC lines for ESD and surge protection. With a low clamping voltage (96.4V maximum at 14A) and fast response time, it effectively safeguards sensitive electronics against voltage spikes in harsh environments. Key advantages include high energy absorption and surface-mount design, though thermal limitations require proper PCB layout consideration. Typical applications span motor drives, power converters, and telecom infrastructure requiring robust overvoltage protection.
