New Fast Body Diode N-Channel MOSFETs
Improve Reliability, Save Energy in Soft
Switching Topologies
Product Benefits:





Low reverse recovery charge (Qrr) increases reliability in
zero voltage switching topologies
Ultra-low on-resistance and gate charge reduce
conduction and switching losses
Offered in TO-220, TO-263, thin lead TO-220F, TO247AD, and TO-247AC packages
Withstand high energy pulses in the avalanche and
commutation mode with guaranteed limits through 100 %
UIS testing
RoHS-compliant and halogen-free
Market Applications:

Switch mode applications including solar inverters, server and telecom power systems, ATX /
Silver box PC SMPS, welding equipment, UPS, battery chargers, and semiconductor capital
equipment
Circuit Topologies:

Designed and developed for “soft switching” or “zero voltage switching” topologies such as:
o Half bridge (LLC)
o Phase-shifted full bridge
o Can be also be used for “hard switching” topologies where the body diode MOSFET
operates only in the first quadrant (never turns on)
 Power factor correction (PFC)
 Two-switch forward converter
 Flyback converter
 Forward converter
Application Note:
o

The News:
Vishay Intertechnology introduces three new devices in its new 600 V EF Series of fast body diode nchannel power MOSFETs. With low reverse recovery charge and on-resistance, the Vishay Siliconix
SiHx21N60EF, SiHx47N60EF, and SiHx70N60EF increase reliability and save energy in industrial,
telecom, computing, and renewable energy applications.
 Built on second-generation superjunction technology
 10x lower Qrr than standard MOSFETs
 Extends Vishay's offering to ZVS / soft switching topologies such as phase-shifted bridges and
LLC converter half bridges

The Perspective:
Built on second-generation superjunction technology, the Vishay Siliconix 600 V EF series of fast
body diode MOSFETs provides a complement to Vishay's existing standard E Series components,
expanding the company's offering to devices that can be used in ZVS / soft switching topologies such
as phase-shifted bridges and LLC converter half bridges. The SiHx21N60EF, SiHx47N60EF, and
SiHx70N60EF increase reliability in these applications by offering a 10x lower Qrr than standard
MOSFETs. This allows the devices to regain the ability to block the full breakdown voltage more
quickly, helping to avoid failure from shoot-through and thermal overstress. The devices' ultra-low onresistance and gate charge translate into extremely low conduction and switching losses to save
energy in high-power, high-performance switch mode applications.
Availability: Samples of the new EF Series MOSFETs are available now. Production quantities will
be available in Q2 2015, with lead times of 18 to 20 weeks for large orders.
