Übersicht
Description
- Low Drain-Source On-Resistance (RDS(on)): Ensures efficient switching.
- High Input Impedance: Ideal for signal amplification and buffering.
- Small Signal Handling: Suitable for RF, audio, and switching circuits.
- SOT-23 Package: Compact and surface-mountable.
Common uses include analog switches, amplifiers, and oscillators. Its low leakage and fast switching make it popular in portable electronics. Always refer to the datasheet for voltage/current limits (e.g., max VDS = 40V).
Equivalent
- 2N5457 (similar characteristics)
- J201 (common substitute)
- BF245B (close match)
- MPF102 (general-purpose replacement)
Check datasheets for exact specs, as pinouts and parameters may vary slightly. For SMD alternatives, consider MMBFJ201 (SOT-23 version of J201). Always verify compatibility in your circuit.
Features
