RN1907,LXHF(CT

Overview

The RN1907,LXHF(CT is an automotive-grade dual NPN digital transistor from Toshiba, designed for point-symmetrical applications. It integrates two NPN transistors with base resistors of 10 kΩ and emitter-base resistors of 47 kΩ. The device supports a collector-emitter voltage (Vceo) of 50 V and a continuous collector current of 100 mA. Key electrical parameters include a minimum DC current gain (hfe) of 80 at -10 mA/-5 V, a maximum operating frequency of 250 MHz, and power dissipation of 100 mW. It operates within a temperature range up to +150°C and is housed in the ES-6 (SOT-563) surface-mount package.

Feature Summary

• Automotive AEC-Q qualified reliability for harsh environment operation
• Point-symmetrical configuration simplifies PCB layout and assembly
• Integrated biasing resistors reduce component count and circuit complexity
• High switching speed suitable for high-frequency signal processing

Applications

• Automotive electronic control units requiring robust switching
• Signal level shifting and logic interface circuits
• Driver stages for relays, solenoids, or small loads
• General-purpose switching in automotive infotainment systems

Procurement Notes

Verify that the specific suffix LXHF(CT) matches the required tape-and-reel packaging format and lead-free compliance status. Confirm AEC-Q qualification requirements against your specific automotive application standards. Ensure the ES-6 footprint dimensions align with your design constraints before finalizing procurement orders.

Selection Notes

Select this component when a symmetrical dual NPN configuration with integrated biasing is required for space-constrained designs. Consider the 250 MHz frequency limit for high-speed applications. Compare against similar Toshiba RN series parts if different resistor values or PNP configurations are needed. Verify thermal management capabilities given the 100 mW power dissipation rating in enclosed environments.

Part Context

This part belongs to Toshiba's RN series of pre-biased bipolar transistors, specifically tailored for automotive electronics. The RN1907 variant provides a dual NPN solution with standardized internal resistance values. It complements other RN series components like the RN2907 (PNP version) and RN1903/1909 variants which offer different resistor ratios for diverse circuit impedance matching needs.

Replacement Considerations

Direct substitutes include RN1907,LF(CT for non-AEC-Q versions and RN2907,LXHF(CT for complementary PNP symmetry. Check equivalent offerings from other manufacturers only if pin-compatible and electrically identical specifications are confirmed through official datasheet cross-referencing.
