The STMicroelectronics SMA4F40A is a unidirectional transient voltage suppressor (TVS) diode from the SMA4FxxA series. Designed for robust protection, this component offers a 40V reverse standoff voltage (VR) and a 44.4V minimum breakdown voltage. It features a low 84V maximum clamping voltage at a peak pulse current of 27A (8/20µs) and a peak pulse power of 400W for surge events. The surface mount SMAflat (DO-221AC) package, supplied on tape and reel, is ideal for high-density applications. This TVS diode is suitable for general-purpose protection in automotive, industrial, and telecommunications equipment. Its wide operating temperature range of -55°C to 175°C (TJ) ensures reliable performance in demanding environments.
