Pinout
The J310 is a JFET (Junction Field-Effect Transistor) with 3 pins:
1. Gate (G): Controls the conductivity between the drain and source.
2. Drain (D): Output terminal where current exits.
3. Source (S): Input terminal where current enters.
It operates as a voltage-controlled switch or amplifier, commonly used in RF and low-noise applications. The J310 is an N-channel JFET, meaning it conducts when the gate-source voltage is sufficiently negative.
Key specs:
- Pinout (TO-92 package): Gate (left), Drain (middle), Source (right).
- Max ratings: ~25V drain-source voltage, ~50mA drain current.
Function: Provides high input impedance and low noise, ideal for signal amplification or switching.

Package
The J310 is a N-channel JFET (Junction Field-Effect Transistor) commonly available in TO-92 or TO-226AA plastic packages. These packages are compact, through-hole types suitable for low-power applications. The TO-92 is a common 3-pin package, while the TO-226AA is a slightly modified variant. Both are widely used in amplification and switching circuits.
