Overview
The Panasonic DRC3143Y0L is a silicon NPN epitaxial planar transistor with built-in resistors, designed for digital circuits. It features a maximum collector-emitter voltage of 50 V and a collector current rating of 100 mA. The device incorporates an internal input resistance (R1) of 4.7 kΩ and an internal base-emitter resistor (R2) of 22 kΩ. Key electrical characteristics include a forward current transfer ratio (hFE) of 60 at 5 mA and a low collector-emitter saturation voltage of 0.25 V at 10 mA. It operates within an ambient temperature range of -40°C to +85°C and supports a junction temperature up to 150°C.
Feature Summary
- Integrated dual-resistor configuration simplifies circuit design by eliminating external components.
- Low collector-emitter saturation voltage ensures efficient switching performance in digital applications.
- High forward current transfer ratio provides reliable gain characteristics across operating temperatures.
Applications
- General-purpose digital logic circuits
- Office equipment signal processing
- Communication equipment interface drivers
Procurement Notes
Verify the specific ordering suffix against official Panasonic documentation to confirm compliance with environmental standards such as EU RoHS and halogen-free requirements. Confirm that the SSSMini3-F2-B package dimensions align with your PCB land pattern specifications before finalizing procurement orders.
Selection Notes
Select this component when a compact NPN switch with integrated biasing is required. Ensure the application current does not exceed 100 mA and the voltage remains below 50 V. Verify thermal management capabilities, as total power dissipation is limited to 100 mW, requiring adequate heat sinking or airflow for high-duty cycles.
Part Context
This part belongs to Panasonic's DRC series of transistors with built-in resistors. It is housed in the SSSMini3-F2-B package, which is equivalent to the SC-105AA form factor. The marking code on the component body is 'N7'. It serves as a complementary device to the PNP type DRA3143Y.
Replacement Considerations
Direct substitutes must match the NPN configuration, 50 V rating, and SSSMini3 package. Verify pinout compatibility and internal resistance values (4.7 kΩ input, 22 kΩ base-emitter) to ensure functional equivalence in existing designs.
FAQ
What are the internal resistance values for the DRC3143Y0L?
The device includes an input resistance (R1) of 4.7 kΩ and a base-emitter resistor (R2) of 22 kΩ.
What is the maximum operating junction temperature?
The maximum junction temperature (Tj) is rated at 150°C.
Is this component suitable for automotive safety-critical applications?
No. Panasonic specifies these products for general applications only. Use in automotive safety devices requires separate agreement and special quality assurance documents.
