STMicroelectronics SMA4F188AY is a unidirectional TVS diode designed for surface mount applications. This component, part of the SMA4F series, offers a reverse standoff voltage of 188V and a peak pulse current capability of 1.4A (10/1000µs). With a clamping voltage of 328V at 1.4A, it provides robust protection against transient overvoltages. The device has a peak pulse power rating of 400W and a breakdown voltage of 209V minimum. Engineered for demanding environments, it operates across a temperature range of -55°C to 175°C. The SMAflat package (DO-221AC) ensures efficient heat dissipation and compatibility with automated assembly processes. This diode is qualified to AEC-Q101 standards, making it suitable for automotive applications.
