DCX124EU-7

Overview

The DCX124EU-7-F is a complementary pre-biased transistor array manufactured by Diodes Incorporated, housed in an SOT363 surface-mount package. It integrates one NPN and one PNP bipolar junction transistor with internal biasing resistors (R1 = 22 kΩ, R2 = 22 kΩ). The device supports a supply voltage of 50 V and handles continuous collector currents up to 100 mA per element. Key electrical characteristics include a minimum DC current gain (hFE) of 100 and a transition frequency (fT) of 250 MHz. Power dissipation is rated at 200 mW, with an operating temperature range spanning from -55°C to +150°C.

Feature Summary

• Integrates dual complementary transistors with built-in biasing resistors for simplified circuit design
• Utilizes a compact SOT363 surface-mount package optimized for automated assembly
• Compliant with RoHS standards and free from halogen and antimony

Applications

• General-purpose switching applications requiring complementary logic control
• Driver circuits for low-power loads utilizing integrated bias networks
• Digital signal interfacing where space-constrained packaging is required

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation before procurement. The standard suffix indicates a 3,000-unit reel quantity. Confirm that the component status remains 'Active' as designated in the latest datasheet revision to ensure long-term availability and manufacturing consistency.

Selection Notes

Select this component when a matched NPN/PNP pair with fixed 22 kΩ biasing resistors is required. Ensure the application voltage does not exceed the 50 V collector-emitter breakdown rating. Verify that the PCB layout accommodates the SOT363 footprint and that thermal constraints align with the 200 mW power dissipation limit under expected ambient conditions.

Part Context

This part belongs to the DCX series of complementary pre-biased transistors offered by Diodes Incorporated. The series provides various resistor combinations within the same SOT363 form factor to accommodate different drive requirements. The DCX124 variant specifically targets applications needing equal 22 kΩ base and emitter resistors for both polarities.

Replacement Considerations

Direct replacements must match the SOT363 package, 50V rating, and 22k/22k resistor configuration. Check competitor datasheets for equivalent hFE and fT specifications. Note that pinout orientations may vary between manufacturers; verify terminal assignments before substitution.
