Overview
The STTH3002CR is a high-efficiency ultrafast recovery diode produced by STMicroelectronics. This device is designed using ST's advanced 200 V planar Pt doping technology, making it particularly suitable for applications in switching mode base drive and transistor circuits. The STTH3002CR is packaged in the I²PAK (TO-262AA) case, which is ideal for low voltage, high frequency inverters, free wheeling, and polarity protection.
