The HUFA75309P3 is a member of the HUFA family of JFETs. It is a single N-channel, dual gate device with an easy ON-OFF delay function. The HUFA75309P3 has a low-power drain-source work capability, making it an ideal choice for a variety of applications.

Major Applications

The HUFA75309P3 is well-suited for RF applications and can be found in use in various electronic systems, such as satellite TV receivers, automotive electronics, and audio/video equipment. It is also used in low-power, low-voltage, and low-noise systems.

The HUFA75309P3 can also be employed in the construction of logic-level switching circuits, making it suitable for supply-voltage governor and rating control systems, as well as for frequency or phase-locked loop systems.

Working Principle

The HUFA75309P3 utilizes an N-channel JFET design with two gate terminals. One gate terminal is the gate-source terminal (G1) and the other is the gate-drain terminal (G2). When the gate-source voltage (VGS) is increased, the current in the channel between the source and the drain increases. Conversely, when the gate-drain voltage (VGD) is decreased, the current in the channel between the source and the drain decreases.

The drain current is controlled by the gate-to-source voltage VGS, while the drain-to-source voltage is controlled by the gate-to-drain voltage VGD. This makes the HUFA75309P3 ideal for use in dual-gate configurations, where the gate-source voltage and gate-drain voltage can be individually controlled. In this way, the HUFA75309P3 can be used to control the drain current, thus enabling the easy ON-OFF delay function.

The HUFA75309P3 has a maximum drain current of 30mA, a maximum drain-source voltage of 20V, and a maximum operating temperature range of -55C to +150C. Furthermore, the HUFA75309P3 features a low power drain-source work capability, with a maximum wattage of 0.2W.
