UNR5210G0L

Overview

The UNR5210G0L is a silicon NPN epitaxial planar transistor with built-in bias resistors, designed for digital circuits. It features an SMini3-F2 package with pin configuration of Base (Pin 1), Emitter (Pin 2), and Collector (Pin 3). The device has a maximum collector current of 100 mA and a total power dissipation of 150 mW at 25°C. Absolute maximum ratings include a collector-emitter voltage of 50 V and a collector-base voltage of 50 V. Electrical characteristics specify a forward current transfer ratio (hFE) minimum of 160 at IC = 5 mA and VCE = 10 V. The transition frequency is rated at 150 MHz.

Feature Summary

• Integrates bias resistors to reduce component count and equipment size
• Supports automatic insertion via tape packing and magazine packing
• Complies with the RoHS Directive (EU 2002/95/EC)

Applications

• Digital circuits
• Office equipment
• Communications equipment
• Measuring instruments
• Household appliances

Procurement Notes

Verify the specific part number against official Panasonic Industry documentation to confirm availability status, as this series may be subject to maintenance or discontinuation phases. Ensure that the required resistance values and electrical parameters match the design specifications before procurement. Cross-reference with the manufacturer's latest product standards to avoid using obsolete components in new designs.

Selection Notes

Select the UNR5210G0L when a pre-biased NPN transistor with a single base resistor is required for digital switching applications. Verify that the 47 kΩ internal base resistor aligns with the drive circuit requirements. Confirm that the SMini3-F2 package dimensions fit the PCB layout constraints. Check if the hFE rank and saturation voltage meet the specific load conditions.

Part Context

The UNR5210G0L belongs to the UNR521xG series of transistors with built-in resistors manufactured by Panasonic Electronic Components. This series offers various combinations of base and emitter resistors to suit different digital logic interface needs. The UNR5210G variant specifically includes only a base resistor, distinguishing it from other models in the family that may feature dual resistors.

Replacement Considerations

Consult official Panasonic distributors for verified substitute part numbers within the UNR521xG series or equivalent products from other manufacturers. Ensure any replacement matches the SMini3-F2 package, 50V rating, and 100mA current capacity.
