Product Overview
MMBFJ111 is a onsemi device in the JFETs category, supplied in a SOT-23 package.
Verified selection data includes Configuration: 1 N-channel, Gate-Source Cutoff Voltage (VGS(off)): 3V, Gate-Source Breakdown Voltage (VGSS): 35V, Power Dissipation (PD): 350mW.
Compared with MMBFJ112, the higher minimum I_{DSS} and lower maximum resistance favor stronger switching, while the same 28 pF on-capacitance remains important.

Selection Notes
Higher-current J111/J112/J113 family position; cutoff voltage; on-resistance; capacitance; package/packing.
Match channel polarity, VGS(off), breakdown voltage, current range and dissipation to the analog switch or bias point.
Manufacturer Decision-Relevant Notes
V_{(BR)GSS} min 35 V; V_{GS(off)} min -3.0 V, max -10 V; I_{DSS} min 20 mA at V_{DS}=15 V, V_{GS}=0; r_{DS(on)} max 30 Ω at V_{DS}≤0.1 V, V_{GS}=0; on-capacitance max 28 pF; off gate capacitances max 5 pF; I_{D(off)} max 1 nA under the cutoff test.
Design Considerations
- Verify -3 to -10 V gate cutoff range; design current and dissipation for process spread; include 28 pF in settling calculations; maintain 35 V gate-breakdown margin.
Application Fit
Low-level analog switching, sample-and-hold, chopper-stabilized amplifiers.
Exact Variant and Procurement Notes
