STTH1R04AY Description

Short technical summary and product information.

The STTH1R04AY is a surface-mount fast recovery rectifier diode from STMicroelectronics, designed for general-purpose rectification and high-frequency switching applications. It is rated for a peak repetitive reverse voltage of 400V and an average rectified current of 1A, with a typical forward voltage of 1.6V at 1A. The diode offers a fast reverse recovery time of 30ns, making it suitable for circuits requiring low switching losses.

 

This diode is housed in a DO-214AC (SMA) package, which is optimized for surface-mount assembly and offers a compact footprint. It supports an operating junction temperature range of -40°C to 175°C, enabling use in demanding environments. The component is classified as a fast recovery diode, with recovery times under 500ns at currents above 200mA.

 

Common applications include power supply rectification, freewheeling diodes in DC-DC converters, and snubber circuits. The surface-mount package simplifies PCB layout and reduces assembly costs compared to through-hole alternatives.
