The MJE4343 is a high-voltage, high-power NPN transistor manufactured by On Semiconductor. It is specifically designed for demanding applications such as high power audio amplifiers and high voltage switching regulator circuits.
Key electrical characteristics include a collector-emitter sustaining voltage of 160 Vdc and a continuous collector current rating of 16 A. The transistor also features a high DC current gain (hFE) of 35 (Typ) at 8.0 Adc and a low collector-emitter saturation voltage (VCE(sat)) of 2.0 Vdc (Max) at 8.0 Adc. The maximum power dissipation is rated at 125 Watts at 25°C.
This device operates over a wide temperature range from -65°C to 150°C. It is available in both TO-247 and SOT-93 packages, with through-hole mounting. The datasheet indicates that the TO-247 package is the primary offering effective June 2012.
The MJE4343 is designed to be Pb-Free, aligning with environmental standards. Its robust specifications make it suitable for applications requiring significant power handling and voltage blocking capabilities.
