TIP41B Discrete Semiconductor Products

TIP41B is a bipolar junction transistor (BJT) belonging to a single category. Specifically, it is a part of the Power Transistor family, which means that it can handle more power load compared to BJT in other categories.

TIP41B is typically used in complementary PNP/NPN configurations to handle higher current loads and built-in protection with its Darlington pair technology against current spikes and electrostatic discharge (ESD) events. TIP41B also provides excellent gain bandwidth and low saturation voltage.

In the application field, the TIP41B can be used in circuits that require high voltage, such as switching between lower voltage sources. The current range of the TIP41B runs to 8 A and its collector-emitter voltage stands at 60 V, which provides enough range for diverse applications. As for the frequency response, it can operate up to 1 MHz, a quite impressive value for BJT transistors.

Inside the TIP41B, there is an integrated circuit consisting of a pair of transistors. Basically, the working principle of the TIP41B follows the one of a traditional BJT, in which it is used as an amplifier and a switch. When current is applied to the base of the transistor, it amplifies the current and conducts it between the collector and the emitter. When the current is removed, the transistor is turned off and no current flows.

TIP41B is one of the most efficient BJT transistors available on the market. Its integrated circuit design provides improved protection against current spikes and ESD events, while still providing excellent gain bandwidth and low saturation voltage, making it an ideal choice for both low and high-power applications.
