RN1103MFV,L3F(CT

Overview

The RN1103MFV,L3F is a bias resistor built-in transistor (BRT) manufactured by Toshiba Semiconductor and Storage. It features an NPN silicon configuration housed in a compact SOT-723 (VESM) surface-mount package. The device integrates internal bias resistors with a base resistance (R1) of 10 kΩ and an emitter-base resistance (R2) of 47 kΩ, establishing a fixed ratio for simplified circuit design. Key electrical specifications include a maximum collector-emitter voltage (Vceo) of 50 V, a continuous collector current (Ic) of 100 mA, and a DC current gain (hFE) minimum of 80 at 10 mA and 5 V. The unit supports a maximum power dissipation of 150 mW and operates within a temperature range suitable for automotive applications.

Feature Summary

• Integrates dual bias resistors to reduce component count and simplify PCB layout
• Automotive-grade qualification compliant with AEC-Q101 standards
• Compact SOT-723 package optimized for space-constrained designs

Applications

• Switching circuits in automotive electronic control units
• Inverter driver circuits
• Interface connection logic level shifting
• General-purpose digital switching applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to confirm pinout compatibility and tolerance grades. Ensure the procurement channel provides valid traceability documentation required for automotive supply chains. Confirm that the reel or cut-tape packaging meets storage humidity sensitivity levels prior to assembly processing.

Selection Notes

Select this component when a fixed 10k/47k resistor ratio is required for NPN switching applications. Compare hFE saturation characteristics against load requirements to ensure adequate drive capability. Verify that the 50V voltage rating exceeds the maximum circuit operating voltage with appropriate safety margins for transient conditions.

Part Context

This part belongs to Toshiba's RN series of bias resistor built-in transistors designed for automotive reliability. The series offers various resistor ratios and polarity options within standardized small-outline packages. The RN1103 variant specifically targets applications requiring moderate input impedance and standard switching speeds in compact form factors.

Replacement Considerations

Direct substitutes must match the NPN polarity, 50V Vceo rating, 100mA Ic limit, and identical 10kΩ/47kΩ internal resistor network. Verify package footprint compatibility with SOT-723 dimensions. Cross-reference thermal dissipation ratings to ensure equivalent performance under similar ambient conditions.
