| Working Voltage |
The SMA6F188AY is a unidirectional TVS diode from STMicroelectronics designed for overvoltage protection. It features a working voltage of 64V, a breakdown voltage of 71.1V typical, and a clamping voltage of 134V at 30A peak pulse current. The device can handle peak pulse power dissipation of 600W (10/1000µs) and 4kW (8/20µs). It offers excellent ESD immunity up to 30kV contact and air discharge per IEC 61000-4-2 and ISO10605, and meets ISO7637-2 pulse requirements for automotive applications. The operating junction temperature range is -55°C to 175°C. The SMA6F188AY is housed in a SMAflat surface mount package (DO-221AC), suitable for automated assembly. Its low leakage current of 0.2µA at 25°C makes it ideal for battery-powered applications.
