UNR411200A

Overview

The UNR411200A is a small signal PNP silicon transistor from the UNR411x series, designed for digital circuits. It features an integrated bias resistor network with R1 and R2 both specified at 22 kΩ. The device utilizes the NS-B1 package, which supports radial taping supply. Key electrical ratings include a collector-emitter voltage (VCEO) of -50 V and a maximum collector current (IC) of -100 mA. The total power dissipation is rated at 300 mW, with a junction temperature limit of 150 °C. The transition frequency (fT) is 80 MHz.

Feature Summary

• Integrates dual bias resistors to reduce component count and equipment size
• Utilizes the NS-B1 package compatible with radial taping supply methods

Applications

• Digital logic interface circuits
• Switching applications requiring built-in base drive resistance
• General-purpose electronic equipment

Procurement Notes

Verify the specific suffix '00A' against official Panasonic documentation to confirm exact resistor tolerance and binning specifications. Confirm current lifecycle status as maintenance or discontinued via manufacturer channels before finalizing procurement plans.

Selection Notes

Select this component when a PNP switching transistor with fixed internal biasing is required. Ensure the circuit operates within the -50 V collector-emitter voltage limit and does not exceed the 100 mA collector current rating. Verify that the 22 kΩ internal resistor values align with the design's base drive requirements.

Part Context

This part belongs to the UNR411x Series of transistors with built-in resistors manufactured by Panasonic Electronic Components. The series offers various resistor combinations to simplify digital circuit designs. The UNR4112 variant specifically provides matched 22 kΩ resistors for both base connections.

Replacement Considerations

Consult official Panasonic replacement lists for verified substitute part numbers. Generic equivalents may not replicate the precise internal resistor ratios or NS-B1 package dimensions.
