Application-specific field-effect transistors (ASFETs) for power in industrial power control from Nexperia
NIJMEGEN, The Netherlands – Semiconductor expert Nexperia in Nijmegen, The Netherlands, is introducing the 80-volt PSMN4R2-80YSE and 100 -volt PSMN4R8-100YSE application-specific field-effect transistors (ASFETs) for telecommunications, computer servers, and industrial applications.
These ASFETs for control of power current in a semiconductor offer enhanced safe operating area (SOA) performance, in hot-swap and soft-start applications that need e-fuse and battery protection.
ASFETs are a breed of metal oxide semiconductor field effect transistor (MOSFET) that focus on parameters critical to an application, sometimes at the expense of others that are less important in the same design.
These hot-swap ASFETs use a combination of silicon technology and copper-clip package construction to strengthen significantly the safe operating area (SOA) and minimize circuit board area.
Previously, MOSFETs have suffered from the Spirito effect, where the SOA performance drops off rapidly because of thermal instability at high voltages. Nexperia's rugged SOA technology increases SOA by 166 percent at 50 volts when compared to previous generations.
The 80-volt PSMN4R2-80YSE and 100 -volt PSMN4R8-100YSE ASFETs are packaged in the Power-SO8-compatible LFPAK56E. The internal copper-clip construction of the package improves thermal and electrical performance while substantially reducing footprint size.
The LFPAK56E products measure 5 by 6 by 1.1 millimeters, and feature a maximum junction temperature of 175 C to meet IPC9592 regulations. For more information contact Nexperia online at www.nexperia.com.
