The P4SMA160A with Diode: transil; 400W; 160V; 1.8A; unidirectional; ±5%; SMA is a high power surge-protection diode from Yangjie. It is designed to prevent transients, surges, and electrostatic discharges in environments and applications requiring very high reliability. Its transil features a 400 W peak pulse power of up to 10/1000 us, a very low capacitance, high breakdown voltage of 160V, and low leakage current, maximum 1.8A. These features make the device suitable for a wide range of applications including high-frequency data transmission on optical fibre networks and digital validation circuits, devices quickly and accurately identifying defective components. It has a unidirectional operation and ±5% tolerance. The package of the P4SMA160A with the Diode transil is available in lead-free and green-soldering-product offering, which is manufactured by Yangjie.
