• Operating Junction Temperature (T_j): -55°C to +150°C
• DC Current Gain (h_FE): 60 (min) to 300 (max) (at V_CE = -5V, I_C = -2mA)
• Built-in Resistors:
• R1 (Base Resistor): 10kΩ
• R2 (Base-Emitter Resistor): 10kΩ

Descriptions:

• The DAN403 is a surface-mount (SMD) digital transistor that integrates bias resistors, simplifying circuit design by reducing external component count.
• It is designed for switching and amplification in low-power applications.
• Suitable for automotive, industrial, and consumer electronics due to its reliability.

Features:

1. Built-in Resistors: Eliminates the need for external base resistors.

2. Compact Package: Comes in a SOT-23 (Miniature Mold) package for space-saving PCB designs.

3. High Voltage Tolerance: Supports up to -50V collector-emitter voltage.

4. Low Saturation Voltage: Ensures efficient switching performance.

5. Pb-Free & RoHS Compliant: Environmentally friendly manufacturing.
