TN2425

TN2425 Low Threshold N-Channel Enhancement-Mode Vertical DMOS FET Features ► ► ► ► ► ► ► ► Low threshold High input impedance Low input capacitance 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 TN2425 is a low threshold enhancementmode (normally-off) transistor that 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 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 Medical ultrasound pulsers Analog switches General purpose line drivers Telecom switches Ordering Information Device TN2425 Package Options TO-243AA (SOT-89) TN2425N8 TN2425N8-G BVDSS/BVDGS 250V RDS(ON) (max) ID(ON) (min) Product marking for TO-243AA: TN4C where = 2-week alpha date code 3.5Ω 1.5A -G indicates package is RoHS compliant (‘Green’) Absolute Maximum Ratings Parameter Drain to source voltage Drain to gate voltage Gate to source voltage Operating and storage temperature Soldering temperature1 Value BVDSS BVDGS ±20V -55°C to +150°C +300°C Pin Configuration D TN2425 Absolute Maximum Ratings are those values beyond which damage to the device may occur.
