Key Features of NJW0281G
- This transistor can operate safely under a wide range of voltage and current combinations without damage.
- The complementary pair (NPN and PNP) has closely matched current gain (hFE or β). Matching within 10% ensures symmetrical performance, which reduces crossover distortion in push-pull amplifier designs.
- The current gain remains consistent over a wide range of collector currents. Important for accurate and linear amplification, minimizing distortion.
- High BVCEO (Collector-Emitter Breakdown Voltage) so this device can handle high voltages without breaking down.
- Pb Free and RoHS Compliant, so transistor is environmentally friendly and compliant with Restriction of Hazardous Substances (RoHS) regulations.
