MUNICH – Nov. 15, 2022 – onsemi (Nasdaq: ON), a frontrunner in clever energy and sensing applied sciences, immediately introduced a sequence of recent MOSFET units that characteristic revolutionary top-side cooling to help designers in difficult automotive functions, particularly inside motor management and DC/DC conversion. The corporate is displaying the brand new units at its sales space 101 in corridor C4 at electronica, the world’s main commerce honest and convention for electronics.

Housed in a TCPAK57 package deal measuring simply 5mm x 7mm, the brand new High Cool units characteristic a 16.5mm2 thermal pad on the highest aspect. This enables warmth to be dissipated instantly right into a heatsink fairly than through a typical printed circuit board (PCB). By enabling using either side of the PCB and lowering the quantity of warmth going into it, the TCPAK57 supplies elevated energy density. Improved reliability of the brand new design provides to an total prolonged system lifetime.

“Cooling is without doubt one of the best challenges in excessive energy design and efficiently addressing it’s the key enabler to decreasing measurement and weight, which is important in trendy automotive design,” mentioned Fabio Necco, vp and normal supervisor, Automotive Energy Options at onsemi. “With glorious electrical effectivity and having eradicated the PCB from the thermal path, the design is considerably simplified whereas decreasing measurement and value.”

The units ship {the electrical} effectivity required in excessive energy functions with RDS(ON) values as little as 1mΩ. Moreover, the gate cost (Qg) is low (65 nC), decreasing losses in high-speed switching functions.

This answer leverages onsemi’s deep experience in packaging to supply the best energy density answer within the trade. TCPAK57 preliminary portfolio contains 40V, 60V and 80V. All units are able to working at junction temperatures (Tj) of 175°C and are AEC-Q101 certified and PPAP succesful. This, together with their gull wings that enables inspection of solder joints and superior board stage reliability, makes them ideally suited to demanding automotive functions. The goal functions are excessive/medium energy motor controls resembling electrical energy steering and oil pumps.
