TN2540 Low Threshold N-Channel Enhancement-Mode Vertical DMOS FET
Features
► ► ► ► ► ► ► ► Low threshold — 2.0V max High input impedance Low input capacitance — 125pF max Fast switching speeds Low ON-resistance Free from secondary breakdown Low input and output leakage Complementary N and P-channel devices
General Description
The Supertex TN2540 is a low threshold enhancementmode transistor that utilizes an advanced 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 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. Supertex’s 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.
Applications
► ► ► ► ► ► ► Logic level interfaces — ideal for TTL and CMOS Solid state relays Battery operated systems Photo voltaic devices Analog switches General purpose line drivers Telecom switches

* Distance of 1.6mm from case for 10 seconds. Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these conditions is not implied. Continuous operation of the device at the absolute rating level may affect device reliability. All voltages are referenced to device ground.
