DRC3144V0L

Overview

The DRC3144V0L is a silicon NPN epitaxial planar digital transistor manufactured by Panasonic Electronic Components. It integrates an internal resistor network within a compact SSSMini3-F2-B package, designed for space-constrained digital circuits. The device features a maximum collector-emitter voltage of 50 V and a continuous collector current rating of 100 mA. Key electrical parameters include a typical input resistance (R1) of 47 kΩ with a tolerance range of -30% to +30%, and a forward current transfer ratio (hFE) of 30 at VCE = 10 V and IC = 5 mA. The component supports an operating ambient temperature range from -40 °C to +85 °C and complies with RoHS standards.

Feature Summary

• Integrates built-in resistors to simplify circuit design and reduce component count in digital switching applications.
• Provides low collector-emitter saturation voltage to minimize power loss during conduction states.
• Utilizes a compact surface-mount package suitable for high-density PCB layouts.

Applications

• General-purpose digital logic interface circuits
• Signal level shifting between different voltage domains
• Driver stages for small-signal loads in office equipment

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to ensure correct packaging and compliance status. Confirm that the component meets the required environmental specifications for the intended application environment before finalizing procurement decisions.

Selection Notes

Select this component when a single NPN digital transistor with a 47 kΩ base resistor is required. Ensure the design accounts for the 100 mA maximum collector current and 50 V voltage limits. Verify thermal dissipation requirements against the 100 mW total power dissipation rating under expected operating conditions.

Part Context

This part belongs to Panasonic's DRC series of transistors with built-in resistors. It serves as the NPN counterpart to the PNP DRA3144V model. The component is housed in the SSSMini3-F2-B package, which is a JEITA-standardized footprint designed for automated surface-mount assembly processes.

Replacement Considerations

The DRA3144V is documented as a complementary PNP device. Direct substitution requires verifying pinout compatibility and ensuring the replacement component matches the required polarity and electrical characteristics for the specific circuit node.
