The JANTXV2N4857 from Solitron Devices is a Radiation-Tolerant Junction Field Effect Transistor that is ideal for military applications. It has a gate-source voltage of -40 V and a drain-source on-resistance of 40 ohms. This junction field effect transistor (JFET) has a power dissipation of less than 1800 mW. It offers features such as low on resistance, fast switching, and high off-isolation. This MIL-PRF-19500/385-qualified JFET includes S-level equivalent screening options and is radiation-tolerant, making it suitable for demanding environments. It is available in a through-hole package that measures 4.95 x 24.38 mm.
