DRA9124X0L

Overview

The DRA9124X0L is a silicon PNP epitaxial planar digital transistor with built-in resistors, housed in an SSMini3-F3-B (SOT-490) package. It features a collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The internal resistor network consists of R1 at 22 kΩ and R2 at 47 kΩ. Key electrical characteristics include a forward current transfer ratio (hFE) of 80 to 400 at IC = -5 mA, and a low collector-emitter saturation voltage of -0.25 V max at IC = -10 mA. Total power dissipation is rated at 125 mW, with an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrated base and emitter resistors for simplified circuit design
• Low collector-emitter saturation voltage for efficient switching
• High forward current transfer ratio for improved gain
• Halogen-free and RoHS compliant construction

Applications

• General-purpose digital logic circuits
• Interface circuits between microcontrollers and loads
• Switching applications in office equipment and measuring instruments

Procurement Notes

Verify the latest product specifications directly with Panasonic before finalizing designs, as datasheets may be updated. Confirm availability status through authorized distributors, as supply conditions can change. Ensure compliance with export control regulations if applicable. Check for specific packaging requirements such as embossed tape reels. Validate that the component meets all necessary environmental standards for the intended application.

Selection Notes

Select this component when a compact PNP digital transistor with integrated biasing is required. The SSMini3 package suits space-constrained surface-mount designs. Verify that the -50V voltage rating and -100mA current capacity meet load requirements. Consider the 22kΩ input resistance for driving interface compatibility. Ensure the operating temperature range aligns with the system environment.

Part Context

This device belongs to Panasonic's series of transistors with built-in resistors, designed specifically for digital circuits. It serves as a complementary component to the DRC9124X and DRA5124X models within the same SSMini3 package family. The marking symbol on the component body is LF. It is manufactured using silicon epitaxial planar technology for reliable performance in standard electronic assemblies.

Replacement Considerations

Direct substitutes are not explicitly listed in the provided documentation. Designers should evaluate other PNP digital transistors with similar -50V ratings, -100mA current capacity, and comparable internal resistor values (R1≈22kΩ, R2≈47kΩ). Package compatibility must be verified if replacing with components from different manufacturers.
