K30A is 50V, 1mA, Silicon N-Chinnel Junction FET.

An N-Channel JFET (N-Type Junction Field-Effect Transistor) is a type of transistor that operates using the principles of a field-effect transistor, specifically designed with an N-type semiconductor material as its channel. It falls under the category of unipolar transistors because it relies on the majority charge carriers (electrons in this case) for its operation. Here are some key points about N-Channel JFETs:

1. Construction: An N-Channel JFET is made up of a bar of N-type semiconductor material, with source and drain terminals connected to the ends of the bar and a gate terminal connected to a region in the middle of the bar. The gate-source junction is reverse-biased.

2. Working Principle: The N-Channel JFET operates based on the modulation of the conductive channel between the source and drain terminals through the application of a voltage at the gate terminal.

3. Depletion Region: When no voltage is applied to the gate terminal, there is a natural conductive path between the source and drain terminals, allowing current to flow. This is due to the depletion region being very narrow under reverse bias.

Absolute Maximum Ratings (Ta=25℃)

1. Gate to Drain voltage : VGDO = -50 V

2. Gate to Source voltage : VGSO = -50 V

3. Gate current : IG = 10 mA

4. Allowable power dissipation : PD = 250 mW

5. Junction Temperature: Tj = 125 ℃

6. Temperature : Tstg = -55 to +125 ℃



For charge sensor, meter amplifier circuit, rheostat , chopper and gain controller for AGC, electronic switch.
