The KRC422E-RTK/P is a digital transistor (DTC) manufactured by KEC (Korea Electronics Co., Ltd.). A digital transistor integrates a transistor with bias resistors internally, simplifying circuit design and reducing the number of external components needed. The '/P' suffix indicates specific packaging or taping options.

Applications:

• Digital Circuit Control
• Inverter Circuits
• Driver Circuits
• Switching Circuits
• Level Shifting

Features:

• NPN Transistor with Integrated Bias Resistors
• Reduces Component Count
• Simplifies Circuit Design
• Surface Mount Package (SOT-23)
• RoHS Compliant
• Bias resistor values R1 = 2.2 kOhm, R2 = 10 kOhm

Benefits:

• Simplified circuit design by eliminating the need for external bias resistors.
• Reduced board space and component count, leading to smaller and more compact designs.
• Improved circuit reliability due to fewer external connections.
• Cost savings from reduced component count and simplified assembly.
• Easy integration into automated assembly lines with surface mount packaging.
• Consistent performance due to integrated resistors.

Specifications:

The KRC422E-RTK/P typically features a collector-emitter voltage (VCEO) rating. The collector current (IC) rating is another important parameter. The integrated resistors typically have values in the kilo-ohm range, providing the necessary biasing for the transistor. The device is packaged in a small SOT-23 surface mount package. Refer to the KEC datasheet for specific electrical characteristics, resistor values, thermal resistance values, and package dimensions. The power dissipation is typically 200 mW. The operating junction temperature is -55°C to +150°C.
