4th Generation EF Series MOSFETs

Vishay / Siliconix 4th Generation EF Series MOSFETs offer an extremely low figure-of-merit (FOM) rating for high-performance switching and high efficiency. The MOSFET FOM is calculated as ON-resistance (R_(DS)ON) multiplied by gate charge (Q_g). Built on Vishay 4th generation super-junction technology, these MOSFETs feature a low typical ON-resistance range of 0.088Ω to 0.225Ω at V_GS=10V and a gate charge down to 21nC. For improved switching performance, these devices provide low effective output capacitances (Co_(er) and Co_(tr)). These values translate into reduced conduction and switching losses to save energy. Vishay / Siliconix 4th Generation EF Series MOSFETs are offered in PowerPAK® 8x8 and TO-220AB packages. The series is designed to withstand overvoltage transients in avalanche mode with guaranteed limits through 100% UIS testing.
