STMicroelectronics SMA4F85A is a unidirectional TRANSIL™ TVS diode designed for transient voltage suppression. This component, part of the SMA4F series, features a reverse standoff voltage of 85V and a breakdown voltage of 95V (minimum). It offers a clamping voltage of 137V at a peak pulse current (Ipp) of 2.9A, with a peak pulse power rating of 400W. The device is housed in a compact SMAflat package (DO-221AC, SMA Flat Leads) suitable for surface mount applications. Operating across a wide temperature range of -55°C to 175°C, the SMA4F85A is utilized in general-purpose applications within various industries requiring robust protection against voltage transients. It is supplied in Tape & Reel (TR) packaging.
