The STMicroelectronics SMA4F33AY is a unidirectional TVS diode from the SMA4F series, designed for robust surge protection. This device offers a 33V reverse standoff voltage and a 53.3V maximum clamping voltage at a peak pulse current of 7.5A (10/1000µs). With a 400W peak pulse power rating, it effectively safeguards sensitive circuitry against transient overvoltages. The component is housed in a compact SMAflat package (DO-221AC, SMA Flat Leads) suitable for surface mounting and is supplied on tape and reel. Engineered for demanding applications, it features an extended operating temperature range of -55°C to 175°C (TJ) and is qualified to AEC-Q101 for automotive use. This device is commonly employed in automotive electronics, industrial control systems, and telecommunications equipment where reliable transient voltage suppression is critical.
