Additional Details

The J113-E3 operates as a voltage-controlled resistor. The voltage applied to the gate terminal controls the current flow between the drain and source terminals. This characteristic makes it suitable for various analog control applications. The specific electrical characteristics, such as breakdown voltage, gate-source cutoff voltage, and transconductance, can be found in the official Vishay Siliconix datasheet.

Proper biasing is essential for optimal performance. The gate voltage must be carefully selected to ensure the transistor operates in the desired region (e.g., ohmic region for switching, saturation region for amplification). It is imperative to refer to the Vishay datasheet for detailed biasing recommendations and performance characteristics.
