RN1402 BIPOLAR TRANSISTOR XB NPN 50V 100MA 200MW SOT-23

The RN1402, marked with “XB” on the package, is a compact and versatile NPN bipolar junction transistor (BJT) designed for various low-power switching and amplification applications.

An NPN BJT acts like an electronic switch or amplifier. By applying a small control voltage (current) to its base, you can regulate a larger current flowing between its collector and emitter terminals. This functionality makes NPN BJTs essential components in many electronic circuits.

Key Features of the RN1402 NPN BJT Transistor:

• • NPN Bipolar Junction Transistor: Belongs to the NPN type, meaning a negative voltage on the base allows current flow between collector and emitter.
  • Low Power: Designed for applications with low voltage and current requirements (typically below 18V and 100mA).
  • SOT-23 Package: Utilizes the compact SOT-23 surface-mount package, ideal for space-saving PCB designs.
  • General-Purpose: Suitable for various switching and amplification tasks in low-power circuits.

Technical Specifications of the RN1402 NPN BJT Transistor:

• • Collector-Emitter Voltage (Vce): The maximum voltage that can be applied between the collector and emitter (usually around 50V).
  • Collector Current (Ic): The maximum continuous current the collector can handle (typically around 100mA).
  • Base Current (Ib): The typical base current required to control the collector current (often in the range of microamps).
  • Gain (hFE): The current gain of the transistor, indicating how efficiently it amplifies current (check datasheet for specific values).

Applications of the RN1402 NPN BJT Transistor:

• • Simple Switching Circuits: Can be used as an electronic switch to turn on/off LEDs, control small motors, or activate other low-power components.
  • Amplifier Circuits (Small Signal): In low-power applications, it can be used in amplifier stages to boost weak voltage signals.
  • Buffer Circuits: Can be configured as a buffer to isolate one circuit stage from another, preventing signal distortion.
  • Logic Level Conversion: In some cases, it can be used for simple logic level conversion between circuits with different voltage requirements (refer to datasheet for specific limitations).

Equivalents of the RN1402 NPN BJT Transistor:

• • Several NPN transistors in the SOT-23 package offer similar functionalities with potential variations in specifications or current ratings. Some examples include the 2N3904, BC547, and SS390. If you can’t find the datasheet for the specific RN1402 variant, you can search for equivalent transistors based on their characteristics and ensure they meet your project’s current and voltage requirements.
