UNR9217G0L

Overview

The Panasonic UNR9217G0L is an NPN epitaxial planar transistor with a built-in base resistor, designed for digital circuits. It features a maximum collector-emitter voltage of 50 V and a continuous collector current rating of 100 mA. The device dissipates up to 125 mW of power within a compact SSMini3-F3 package. Key electrical characteristics include a transition frequency of 150 MHz and a forward current transfer ratio (hFE) ranging from 6 to 460 depending on operating conditions. The internal circuitry integrates a single 22 kΩ resistor connected to the base terminal.

Feature Summary

• Integrates a fixed resistance network directly with the transistor die to minimize external component count.
• Utilizes a small surface-mount SSMini3 package to facilitate automated assembly and board space reduction.

Applications

• Digital logic interface circuits
• Switching applications in consumer electronics
• General-purpose signal processing stages

Procurement Notes

Verify the specific suffix 'G' against the manufacturer's latest lifecycle status, as this series may be subject to maintenance or discontinuation phases. Confirm RoHS compliance documentation matches the required environmental standards for your manufacturing process. Ensure the ordering code corresponds exactly to the UNR921xG series datasheet specifications.

Selection Notes

Select this component when a pre-biased NPN transistor with a 22 kΩ base resistor is required for low-current switching tasks. Consider the 50 V breakdown voltage and 100 mA current limit to ensure adequate headroom for the target application. Evaluate the thermal performance within the SSMini3 package constraints if high ambient temperatures are expected.

Part Context

This part belongs to the UNR921xG series of transistors with built-in resistors. The series offers various resistance values and configurations to suit different biasing requirements. The 'G' suffix typically denotes specific packaging or compliance variations within the broader UNR921 product family.

Replacement Considerations

Consult official cross-reference lists for direct substitutes. Verify that any alternative maintains the same pinout, voltage ratings, and integrated resistance value to ensure circuit compatibility without redesign.
