2N5638 Datasheet, PDF (1/4 Pages) Fairchild Semiconductor – N-Channel Switch

2N5638, 2N5639
2N5638 is a Preferred Device
JFET Chopper Transistors
N–Channel – Depletion
N–Channel Junction Field Effect Transistors, depletion mode (Type
A) designed for chopper and high–speed switching applications.
• Low Drain–Source “ON” Resistance:
RDS(on) = 30Ω for 2N5638
RDS(on) = 60Ω for 2N5639
• Low Reverse Transfer Capacitance
Crss = 4.0 pF (Max) @ f = 1.0 MHz
• Fast Switching Characteristics
tr = 5.0 ns (Max) (2N5638)
