J310RLRP

Overview

The J310RLRP is an N-channel depletion-mode JFET designed for VHF/UHF amplifier applications. It operates within a drain-source voltage of 25 Vdc and dissipates up to 350 mW at 25°C ambient temperature. The device features a gate-source cutoff voltage ranging from -2.0 Vdc to -6.5 Vdc and a zero-gate-voltage drain current between 24 mA and 60 mA. At 100 MHz, it provides a common-gate power gain of approximately 16 dB with a forward transconductance of 12 mmhos. Packaged in a TO-92 (Case 29-11) format, it supports tape and ammo box shipping configurations.
