Designed for use in high ambient temperature environments, Diodes Incorporated has announced two 40V automotive-compliant MOSFETs operating at up to +175°C. The DMTH4004SPSQ has been designed to meet the requirements of high-power (>750W) BLDC applications, such as water and fuel pumps, while the DMTH4005SPSQ is suited to lower power BLDC applications, such as auxiliary pumps and HVAC systems.
Developed to meet the rigorous demands of three phase BLDC motor control applications, the DMTH4004SPSQ and DMTH4005SPSQ are 100% avalanche tested, ensuring a robust design that is able to withstand the high pulses of reverse avalanche energy that can occur with inductive loads. Furthermore, at a gate-source voltage of 10V, the DMTH4004SPSQ and DMTH4005SPSQ feature maximum on‑state resistances of 2.7 and 4mΩ, respectively, which together with their low gate charge ensures that power losses are kept to a minimum.
The efficiency of these MOSFETs is further enhanced by the low thermal resistance of the POWERDI 5060-8 package. This allows for a maximum junction temperature of +175°C ensuring that these MOSFETs are able to operate in high ambient temperature environments.
The DMTH4004SPSQ and DMTH4005SPSQ are priced at $0.50 and $0.64 each, respectively, in 3,000 unit quantities.
