230ºC silicon power MOSFETs have integrated drivers

February 03, 2015 // By Graham Prophet
X-REL Semiconductor (France), fabless semiconductor specialist maker of devices rated for long-term operation at high temperatures, has added the XTR20410 and XTR20810 high-temperature families of N-channel Power MOSFET with integrated driver circuitry.

These product families are intended for power conversion applications in highly demanding markets including aerospace, industrial, hybrid and electric vehicles, transportation, geothermal and oil and gas.

The XTR20410 and XTR20810 product families consist of power N-channel MOSFETs and integrated drivers tailored for use in extreme reliability and high temperature applications, such as DC/DC converters, motor control and power switching.

Matching network optimisation between a driver and a power transistor is, says X-Rel, a difficult and time-consuming task: these devices provide users with a turn-key solution that already matches power transistor and driver inside a single piece of silicon.

XTR20410 parts may be used as high-side (40V max), low-side, or low-side switch with negative offset (-30V max) on the output stage (source connected to a negative voltage), while receiving a control input signal referred to GND.

XTR20810 parts are intended to be used as low-side switches, and are able to sustain transient overshoot voltages up to 100V.

Devices in the XTR20x10 families are able to reliably operate from -60°C to well above +230°C (5 years at +230°C). All X-REL Semiconductor products can be used in applications running at lower temperatures (e.g. from 100°C to 200°C) where extended lifetime is expected or where failing is not an option. For example, the expected lifetime of X-REL Semiconductor parts in an application operating at Tj=150°C is over 35 years.

Parts from XTR20410 and XTR20810 families can be packaged in both niche and large-scale markets in high-reliability compact hermetic or plastic packages, as well as bare dice.
