UNR411300A

Overview

The Panasonic UNR411300A is a Silicon PNP epitaxial planar transistor with built-in resistors, designed for digital circuits. It utilizes the NS-B1 package and operates with negative voltage polarities. Key absolute maximum ratings include a collector-base voltage (V_CBO) of -50 V, a collector-emitter voltage (V_CEO) of -50 V, and a continuous collector current (I_C) of -100 mA at 25°C. The device supports a total power dissipation (P_T) of 300 mW and functions within a junction temperature range up to 150°C. Storage temperatures extend from -55°C to +150°C.

Feature Summary

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

Applications

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

Procurement Notes

Verify the specific suffix '00A' against official Panasonic documentation to confirm exact resistance values and binning. Confirm current lifecycle status as maintenance or discontinued via the manufacturer's website before finalizing procurement plans.

Selection Notes

Select this component when a compact PNP switching solution with integrated base and pull-down resistors is required. Ensure the design accommodates negative supply voltages and verify that the -100 mA collector current rating meets the load requirements.
