Nexperia launches new Trench Schottky rectifier

Designed to improve efficiency for fast switching applications

New AEC-Q101 qualified devices support voltages up to 100 V and currents up to 20 A with low switching losses and increased safe operating area

Nijmegen, May 10, 2021: Nexperia, the expert in basic semiconductor components, has expanded its Trench Schottky rectifier product portfolio with new devices rated up to 100 V and 20 A, with excellent switching performance and leading thermal performance. The new devices are packaged in Nexperia's clip-on FlatPower (CFP) package, which has a much smaller footprint than SMA/SMB/SMC devices. 

The Trench process significantly reduces the Qrr charge stored in the device while reducing leakage current. As a result, Trench Schottky rectifiers can achieve ultra-fast switching speeds, reducing both the switching losses of the rectifier and the losses generated by the MOSFET in the same commutation unit (this configuration is commonly used in asynchronous switch-mode power converters). Nexperia's PMEGxxxTx devices also offer a wide safe operating area (SOA), which has a larger safety margin and reduces the risk of thermal runaway compared to currently available devices.

“Nexperia’s Trench Schottky rectifiers combine low forward voltage drop with very low Qrr to achieve optimum efficiency while delivering the high switching speeds required for switch-mode power converters,” said Jan Fischer, Product Manager at Nexperia. “Many automotive applications, including LED lighting, will benefit from the wide safe operating area our devices offer.”

Nexperia is increasing its investment in the Trench Schottky rectifier portfolio, with 31 devices now in volume production, covering a rating range of 40 V to 100 V and up to 15 A. A further 17 devices, including several at 20 A, are undergoing sample evaluation. The PMEGxxxTx devices are available in the clip-on FlatPower package (CFP3/5/15(B)). This space-saving and thermally efficient package has become the industry standard for power diodes. The clip-on FlatPower package uses a solid copper clip to reduce thermal resistance and better conduct heat to the surrounding environment, making the PCB smaller and more compact.
