Description

An N-channel, 600V, 7A power MOSFET refers to a specific type of power Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) that has an N-channel as the conducting channel and is designed to handle a maximum voltage of 600 volts and a continuous current of up to 7 amperes. MOSFETs are widely used in power electronic applications for their ability to efficiently switch and control high voltages and currents.

The SuperMESH series is obtained through an extreme optimization of ST’s well established strip-based  PowerMESH™ layout. In addition to pushing on-resistance significantly down, special care is taken to ensure a very good dv/dt capability for the most demanding applications. Such series complements ST full range of high voltage MOSFETs including revolutionary MDmesh™ products.

Applications:
1. HIGH CURRENT, HIGH SPEED SWITCHING
2. IDEAL FOR OFF-LINE POWER SUPPLIES, ADAPTORS AND PFC

Features:

1. TYPICAL RDS(on) = 0.85 W
2. EXTREMELY HIGH dv/dt CAPABILITY
3. IMPROVED ESD CAPABILITY
4. 100% AVALANCHE RATED
5. GATE CHARGE MINIMIZED
6. VERY LOW INTRINSIC CAPACITANCES
7. VERY GOOD MANUFACTURING REPEATIBILITY
