TP2540

TP2540 P-Channel Enhancement Mode Vertical DMOS FETs Features ► Low threshold (-2.4V max.) ► High input impedance ► Low input capacitance (125pF max.) ► Fast switching speeds ► Low on-resistance ► Free from secondary breakdown ► Low input and output leakage Applications ► Logic level interfaces - ideal for TTL and CMOS ► Solid state relays ► Battery operated systems ► Photo voltaic drives ► Analog switches ► General purpose line drivers ► Telecom switches General Description This low threshold enhancement-mode (normally-off) transistor utilizes a vertical DMOS structure and Supertex’s 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 thermallyinduced secondary breakdown. Supertex’s v...
