Microchip Technology, Inc. 400V N-Channel Enhancement-Mode MOSFET TN2640

This low threshold enhancement-mode (normally-off) transistor utilizes a vertical DMOS structure and well-proven silicon-gate manufacturing process. This combination produces a device with the power handling capabilities of bipolar transistors and with the high input impedance and positive temperature coefficient inherent in MOS devices. Characteristic of all MOS structures, this device is free from thermal runaway and thermally induced secondary breakdown. Vertical DMOS FETs are ideally suited to a wide range of switching and amplifying applications where very low threshold voltage, high breakdown voltage, high input impedance, low input capacitance, and fast switching speeds are desired. Additional Features Low threshold (2.0V max.) High input impedance Low input capacitance Fast switching speeds Low on-resistance Free from secondary breakdown Low input and output leakage
