18TQ035STRL

Diodes - Rectifiers - Single

The 18TQ035STRL is a rectifier diode from STMicroelectronics, providing a 35 Amp and 200 Volt rating. Designed for the purpose of single-phase power rectification, it uses the properties of diodes to center an electric signal around a reference voltage level. This makes it useful for processes like AC-DC power supplies, battery charging, and overvoltage protection.

The 18TQ035STRL is typically housed in the SOT-227J surface-mount package, but is also available in a TO-220AB plastic package. It features a low forward voltage drop of 0.85V. Maximum average forward current is 35A and maximum peak forward surge current is 7A. The maximum reverse wave leakage current is 2uA. It\'s operative temperature range is between -55°C and 150°C.

The 18TQ035STRL provides both reliability and convenience with its fast recovery time due to a low junction capacitance of 600pF. The device features a monolith construction, meaning that the junction and package are integrated into a single body. This makes them well-suited for pulsed mode applications. Furthermore, the -40V maximum average-rectified peak reverse voltage ensures the device withstands high voltage spikes.

The 18TQ035STRL is engineered for use in a variety of applications, such as AC-DC converters, DC-DC converters, simple PFC applications, and backlight inverters in LCD TVs. Its capability for peak power handling makes it a good choice for single-phase rectification and high peak power demands in flyback converters. In a signal processing context, it can be used to control signal swing and reduce signal distortion, ensuring a clean and accurate signal.

The working principle of the diode is relatively simple. It acts as a one-way gate: when forward bias is applied to the diode, it becomes conductive, and when the voltage stops, the diode immediately switches back to a high-impedance state. In the reverse bias condition, all electric current is blocked. Thus, the device can be used to rectify alternating current into direct current efficiently, while also limiting the maximum voltage.

The 18TQ035STRL diode offers a reliable solution for single-phase rectification thanks to its low forward voltage drop, fast recovery time, and peak reverse voltage capability. It can be used in a variety of applications, from DC-DC converters to signal processing. By understanding the working principle of a diode and its capabilities, engineers can easily choose the ideal component for their project.
