ES1A Description

Short technical summary and product information.

The ES1A is a 1.0A ultra fast recovery rectifier designed for surface mount applications. It features a glass passivated junction and a low profile DO-214AC SMA package for easy pick and place assembly. The device offers a maximum repetitive peak reverse voltage of 50V and an average rectified forward current of 1.0A at 120°C ambient.

 

Key electrical characteristics include a forward voltage of 920mV at 1A, a reverse recovery time of 15ns, and a non-repetitive peak forward surge current rating of 30A (8.3ms half-sine-wave). The device is rated for an operating junction temperature range of -50°C to +150°C and has a maximum power dissipation of 1.47W.

 

The ES1A is supplied in tape and reel packaging with a standard quantity of 7500 units per reel. It is Pb-Free and RoHS compliant, suitable for general purpose rectification and high efficiency power conversion applications.
