RN1310(TE85L,F)

Overview

The RN1310(TE85L,F) is a pre-biased NPN bipolar junction transistor manufactured by Toshiba Semiconductor and Storage. It integrates a single NPN transistor with a built-in bias resistor in an SC-70 (USM) surface-mount package. The device features a collector-emitter voltage of 50 V, a continuous collector current of 100 mA, and a maximum power dissipation of 150 mW. It includes a built-in bias resistor ratio of 0.47 and offers a minimum DC current gain (hFE) of 50.

Feature Summary

• Integrates NPN transistor with built-in bias resistor for simplified circuit design
• Compact SC-70 surface-mount package suitable for space-constrained applications
• High collector-emitter voltage rating of 50 V

Applications

• General-purpose switching circuits
• Small signal amplification stages
• Logic interface buffering

Procurement Notes

Verify the exact manufacturer designation, as sourcing may list Toshiba or Toshiba Semiconductor and Storage. Confirm the SC-70 package type and pinout compatibility with your PCB footprint. Ensure the built-in resistor ratio matches your biasing requirements. Check RoHS compliance status if required for your specific manufacturing standards.

Selection Notes

Select this component when a compact NPN switch with integrated biasing is needed. The 50 V rating supports moderate voltage levels. The 100 mA current capacity suits low-power signaling tasks. Consider the 150 mW power dissipation limit for thermal management in dense layouts. Compare against other SC-70 digital transistors if higher gain or different resistor ratios are required.

Part Context

This part belongs to Toshiba's discrete semiconductor product line, specifically within the category of pre-biased bipolar transistors. It is designed for surface-mount technology (SMT) assembly. The SC-70 package provides a small form factor compared to traditional through-hole alternatives, facilitating automated placement in modern electronics manufacturing processes.
