Description
This new generation of trench MOSFETs from Zetex utilizes a unique
structure that combines the benefits of low on-resistance with fast
switching speed. This makes them ideal for high efficiency, low voltage
power management applications.
Features
• Low on-resistance
• Fast switching speed
• Low threshold
• Low gate drive
