500-V n-channel power MOSFET offers improved switching speed
April 01, 2010 // Paul Buckley
Vishay Intertechnology, Inc., has unveiled a new 500-V n-channel power MOSFET with improved switching speed and losses compared to previous-generation devices.
Suitable for ZVS topologies, the SiHF8N50L-E3 offers a low trr of 63 ns and Qrr of 114 nC, with an improved gate charge of 34 nC.
The SiHF8N50L-E3's improved reverse recovery characteristics result in better EMI immunity and better efficiency, while avoiding internal body diode recovery failures that cause MOSFET burn-out.
The new MOSFET combines its 500-V rating with a low 1.0-ohm maximum on-resistance at a 10-V gate drive. This low RDS(on) translates into lower conduction losses that save energy in LLC, full-bridge, half-bridge, and double-forward topologies for LIPS inverters, HIDs, PC power supplies, and ballasts.
For reliable operation, the device is 100 percent avalanche tested. Peak current handling is 22 A pulsed and 8 A continuous (limited by maximum junction temperature). Offered in the TO-220 FULLPAK package, the SiHF8N50L-E3 is compliant to RoHS Directive 2002/95/EC.
Availability
Samples and production quantities of the new power MOSFET are available now, with lead times of eight to 10 weeks for larger orders.

The development platform for i.MX 6Quad from element14 (built to the Freescale SABRE Lite design) is an evaluation platform featuring the powerful i.MX 6Q, a multimedia application processor with Quad ARM Cortex-A9 cores at 1.2 GHz from Freescale Semiconductor.
This month, Freescale and element14 are giving away five such platforms, worth £128.06 each, for EETimes Europe's readers to win. The platform helps evaluate the rich set of peripherals and includes a 10/100/Gb Ethernet port, SATA-II, HDMI v1.4, LVDS, parallel RGB interface, touch screen interface, analog headphone/microphone, micro TF and SD card interface, USB, serial port, JTAG, camera interface, and input keys for Android.
And the winners are...
In our previous reader offer, Pico Technology was giving away one of its recently launched PicoScope 3207B, a 2-channel USB 3.0 oscilloscope worth 1451 Euros. Lucky winner Mr L. Sanchez-Gonzalez from Spain should be receiving his PicoScope 3207B soon. Let's wish them some interesting findings with his projects.
