Unlike the more common enhancement-mode FET, this part conducts with zero gate-source voltage and requires a negative Vgs to turn off. That makes it a natural choice for normally-on current sources, cascode stages, or start-up circuits where you need conduction until the controller takes over. The 6 Ω maximum on-resistance is specified at 350 mA drain current with 10 V on the gate.","metaTitle":"Infineon BSP129L6906 SIPMOS N-Ch Depletion MOSFET, 240V, 6Ω","metaDescription":"Infineon BSP129L6906 N-channel depletion-mode MOSFET, 240V Vdss, 6Ω Rds(on) at 10V, PG-SOT223-4.
