Vishay 1-Element Uni-Directional TVS Diode 4 kW 2-Pin DO-221 SMA6F18A-M3/6A

Vishay SMA6F18A-M3/6A is a 1-element uni-directional transient voltage suppression (TVS) diode designed for high-performance circuit protection in electronic devices. It delivers up to 4 kW of peak pulse power dissipation, making it suitable for safeguarding sensitive semiconductor components and circuits from voltage spikes and transient surges.

This diode features a surface mount DO-221 package with compact dimensions of 4.35 mm length, 2.7 mm width, and 1 mm height. It is designed to operate reliably within a temperature range from -55°C to 175°C, ensuring robust performance under harsh environmental conditions commonly found in industrial, automotive, and electronic applications.

The SMA6F18A-M3/6A model has a minimum breakdown voltage (Vbr) of 20 V and a maximum reverse stand-off voltage (Vwm) of 18 V. Its clamping voltage (Vc) is 33.2 V, which ensures circuit voltage stays within safe levels during transient events. The device offers ESD protection and supports a maximum peak pulse current (Ippm) of 102 A, effectively preventing current surges that could damage electronic components.

This TVS diode is specifically suitable for applications requiring transient voltage suppression such as power supplies, automotive electronics, industrial machinery, and communication equipment. Its low maximum reverse leakage current of 1 μA contributes to high efficiency and reduced power dissipation in normal operating conditions.

The product is part of Vishay's eSMP series and is manufactured in China under strict quality standards. It is ideal for PCB designers and engineers looking for reliable and compact TVS diodes with guaranteed performance.
