DESCRIPTION
Silicon N-channel enhancement mode vertical D-MOS transistor designed for industrial and military applications in the HF/VHF frequency range. The transistor is encapsulated in a 4-lead, SOT121 flange envelope, with a ceramic cap. All leads are isolated from the flange. A marking code, showing gate-source voltage (V GS ) information is provided for matched pair applications. Refer to the 'General' section for further information. PINNING - SOT121 PIN DESCRIPTION 1 drain 2 source 3 gate 4 source PIN CONFIGURATION CAUTION The device is supplied in an antistatic package. The gate-source input must be protected against static charge during transport and handling. WARNING Product and environmental safety - toxic materials This product contains beryllium oxide. The product is entirely safe provided that the BeO disc is not damaged. All persons who handle, use or dispose of this product should be aware of its nature and of the necessary safety precautions. After use, dispose of as chemical or special waste according to the regulations applying at the location of the user. It must never be thrown out with the general or domestic waste.
