XTR2K0x08 is a family of 80mΩ depletion jFETs with maximum operation voltages between 150V and 300V designed to reliably operate from -60°C to +230°C, with junction temperature able to reach +250°C.

Fabricated on a Silicon Carbide (SiC) process, XTR2K0x08 parts offer reduced leakage currents while offering low RDS(on) and gate charge (Qg). These features allow XTR2K0x08 parts to be ideally suited for linear as well as for switching applications.

Parts from the XTR2K0x08 family are available in ruggedized 3-lead TO257, 8-lead side brazed DIP and 8-lead SOIC-like with ePAD.

XTR20810 is a family of extremely flexible power N-channel MOSFETs with integrated driver designed for extreme reliability and high temperature applications such as DC/DC converters, motor control and power switching. XTR20810 parts are intended to be used as low side switches. They can sustain drain spikes up to 100V. XTR20810 parts can be directly driven by any 5V digital output, making them fully plug-and-play devices, avoiding any time consuming optimization of the matching network between driver and power transistor.
