RN1315,LXHF

Overview

The RN1315,LXHF is a digital transistor array manufactured by Toshiba Semiconductor and Storage, featuring two complementary NPN/PNP transistors in a single surface-mount package. It operates with a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA. The device includes built-in bias resistors, typically 10kΩ for both base and emitter connections, simplifying circuit design. With a transition frequency of 250MHz and a power dissipation rating of 100mW, it is suitable for high-speed switching applications. The component is AEC-Q101 qualified for automotive use and is housed in an SOT-363 (SC-88) package.

Feature Summary

• Integrated dual complementary NPN/PNP configuration reduces component count
• Built-in bias resistors simplify interface circuit design
• AEC-Q101 qualification ensures reliability for automotive environments
• High-speed switching capability with 250MHz transition frequency

Applications

• Switching circuits requiring complementary logic levels
• Inverter circuits for signal inversion
• Interface circuits between microcontrollers and peripheral devices
• Driver circuits for low-power loads

Procurement Notes

Verify the complete part number including the LXHF suffix to ensure correct packaging and compliance specifications. Confirm AEC-Q101 automotive qualification requirements if deploying in vehicle systems. Check datasheet for thermal derating curves relative to ambient temperature. Ensure PCB footprint matches the SOT-363 package dimensions. Validate resistor values against specific application needs as they are fixed internally.

Selection Notes

Select this component when a compact solution for complementary NPN/PNP switching is required. The fixed 10kΩ internal resistors suit standard TTL/CMOS logic interfaces. Consider the 100mA current limit for load driving capabilities. The SOT-363 package offers space efficiency compared to discrete transistor pairs. Verify operating temperature range meets system environmental constraints.

Part Context

The RN1315 belongs to Toshiba's RN series of digital transistors, which integrate bias resistors directly onto the silicon die. This series is designed to replace multiple discrete components, reducing board space and assembly costs. The LXHF suffix indicates RoHS compliance and specific tape-and-reel packaging. It complements other RN series parts like the RN1314 or RN2315 depending on polarity requirements.

Replacement Considerations

Direct substitutes include the RN1314 (NPN/NPN) or RN2315 (PNP/PNP) from Toshiba if polarity differs. Cross-manufacturer equivalents should match the 50V VCEO, 100mA IC, and SOT-363 package. Verify internal resistor values and hFE characteristics before substitution to ensure circuit compatibility.
