UNR411E00A

Overview

The UNR411E00A is a small signal PNP silicon epitaxial planar transistor from the UNR411x Series, designed for digital circuits. It features an integrated bias resistor network with R1 at 47 kΩ and R2 at 22 kΩ, yielding a resistance ratio of approximately 2.14. The device operates within a collector-emitter voltage limit of -50 V and supports a maximum collector current of -100 mA. Total power dissipation is rated at 300 mW at 25°C ambient temperature. Transition frequency reaches 80 MHz under specified conditions.

Feature Summary

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

Applications

• Digital logic interface circuits
