RN2906FE,LF(CT

Overview

The RN2906FE,LF(CT is a dual PNP digital transistor from Toshiba Semiconductor and Storage, designed for automotive applications under the AEC-Q101 qualification standard. It integrates two PNP transistors with built-in bias resistors in a compact US-6 (SOT-363) surface-mount package. Key electrical specifications include a collector-emitter voltage (VCEO) of -50 V, a continuous collector current (IC) of -100 mA, and a power dissipation (Pd) of 200 mW. The internal resistor configuration consists of R1 = 4.7 kΩ and R2 = 47 kΩ, yielding a typical resistance ratio of 0.1. The device features a minimum DC current gain (hFE) of 80 and an emitter-base voltage (VEBO) of 5 V, operating within a temperature range up to +150°C.

Feature Summary

• Automotive-grade reliability certified by AEC-Q101 standards for high-duty-cycle environments
• Integrated dual PNP structure with fixed bias resistors simplifies circuit design
• Compact US-6 package enables high-density mounting on printed circuit boards

Applications

• Switching circuits in automotive electronic control units
• Inverter driver circuits for motor control systems
• Interface connection buffers between logic gates and loads
• General-purpose switching applications requiring compact form factors

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and tape/reel specifications. Ensure compatibility with automated pick-and-place equipment requirements for the US-6 footprint. Confirm RoHS compliance status through official datasheets prior to integration into regulated assemblies.

Selection Notes

Select this component when dual PNP switching with integrated biasing is required in space-constrained designs. The -50V rating suits low-voltage automotive logic levels. Verify thermal management needs as the 200mW dissipation limit requires adequate PCB copper area for heat spreading in high-frequency switching scenarios.

Part Context

This part belongs to Toshiba's RN series of pre-biased transistors, which combine bipolar junction transistors with internal resistors to reduce external component count. The RN2906 variant specifically provides dual PNP configurations, distinguishing it from NPN or complementary NPN/PNP counterparts in the same family.

Replacement Considerations

Direct substitutes may include other dual PNP digital transistors in SOT-363 packages with matching VCEO and IC ratings. Verify pinout compatibility and internal resistor values (R1/R2) before substitution. Alternative packages like SC-88 or SOT-363 variants from other manufacturers require careful electrical parameter comparison.
