TSDF1220 Description

Short technical summary and product information.

The Vishay TSDF1220 is a Silicon NPN Planar RF Transistor suitable for low noise applications such as preamplifiers, mixers, and oscillators in analog and digital TV systems, extending up to microwave frequencies.

Key electrical characteristics include a high transition frequency (fT) of 12 GHz, a very low noise figure of 1.2 dB at 2 GHz, and a power gain of 14 dB. The transistor operates with a collector-emitter voltage (VCEO) of 6V and a maximum collector current (IC) of 40mA. Its compact size and performance make it ideal for demanding RF designs.

Available in various plastic packages including SOT-143, SOT-143R, SOT-343, and SOT-343R, the TSDF1220 is designed for surface mounting. The absolute maximum ratings specify a junction temperature up to 150°C and a storage temperature range from -65°C to +150°C.

This RF transistor is well-suited for applications requiring high performance and low noise, such as in satellite tuners and other high-frequency communication systems.
