The BCR35PN is a digital PNP Bipolar Junction Transistor (BJT) with integrated resistors, manufactured by Infineon Technologies (formerly Siemens). Similar to the BCR192, these transistors are designed to simplify circuit design by incorporating bias resistors, thereby reducing the external component count and saving board space.

Applications:

• Switching circuits.
• Inverter circuits.
• Driver circuits.
• Digital applications requiring PNP transistors.

Features:

• Integrated bias resistors (R1 = 47 kΩ, R2 = Open).
• Reduces component count.
• Simplifies circuit design.
• Available in small SMD packages.

Benefits:

• Lower overall system cost.
• Reduced board space requirements.
• Improved circuit performance due to optimized resistor values.
• Easier assembly and manufacturing.

The BCR35PN is well-suited for applications requiring a PNP transistor with a defined input resistance. The integrated resistor ensures a consistent bias voltage, leading to reliable circuit performance. It is typically available in small surface-mount packages like SOT-323, making it suitable for compact circuit designs.

Technical Specifications (typical):

• Collector-Emitter Voltage: -50 V
• Collector Current: -100 mA
• Total Power Dissipation: ~250 mW (dependent on package and ambient temperature)
• DC Current Gain: Dependent on variant (check datasheet)
