BC 141 NPN

The BC 141 NPN is a versatile sensor module designed for reliable electronic switching and control applications. Engineered for consistent performance, it integrates smoothly with a variety of control circuits and switching arrangements where robust, repeatable transistor behavior is required. Key electrical characteristics include a collector current rated up to 100 mA, a maximum collector-emitter voltage of 45 V, and a low saturation voltage of approximately 0.2 V. The device offers high gain with an hFE range from 100 to 300, supporting amplification and signal-conditioning needs while minimizing voltage drop and power loss during conduction. Collector current up to 100 mA for effective switching of diverse loads. Maximum collector-emitter voltage 45 V for medium-voltage operation. High gain (hFE 100–300) for amplification stability in sensor circuits. Low saturation voltage (~0.2 V) to reduce conduction losses. Operating temperature range −55°C to +150°C for demanding environments. Compared with common NPN transistors, the BC 141 NPN combines a higher current capability and a wider operating temperature range than typical models such as the BC 547, making it suitable for applications that require enhanced durability and thermal tolerance. Its semiconductor construction promotes fast switching speeds while reducing thermal stress, and the stable gain and low saturation characteristics help improve circuit responsiveness and energy efficiency. Recommended uses include general-purpose switching, driver stages, sensor interfaces, and control circuitry where dependable transistor performance across a broad temperature range is important.
