BZW50-27

BZW50-27 Description

The BZW50-27 from STMicroelectronics is a unidirectional Zener-type TVS diode designed for general-purpose transient voltage suppression in electronic circuits. Part of the BZW50, TRANSIL™ series, it offers robust protection with a 27V reverse standoff voltage (Typ) and a minimum breakdown voltage of 30V. Its 62V maximum clamping voltage @ Ipp ensures effective suppression of transient spikes, while handling peak pulse currents up to 968A (8/20µs) and peak pulse power of 5000W (5kW). The device features low capacitance (7000pF @ 1MHz), making it suitable for high-speed signal lines. Packaged in through-hole format, it complies with ROHS3 and REACH standards, ensuring environmental and regulatory compatibility.
