TLX9310(TPL,F

Overview

The TLX9310(TPL,F is a single-channel automotive-grade logic output optoisolator manufactured by Toshiba Semiconductor and Storage. It features a push-pull/totem pole output configuration with a data rate of 5Mbps. The device provides an isolation voltage of 3750Vrms and a common-mode transient immunity (CMTI) of 25kV/µs. Key electrical parameters include a maximum propagation delay of 250ns for both low-to-high and high-to-low transitions, with typical rise and fall times of 11ns and 13ns respectively. It operates on a supply voltage range of 2.7V to 5.5V, supports a maximum DC forward current of 8mA, and delivers an output current of 10mA per channel.

Feature Summary

• Automotive qualification compliant with AEC-Q101 standards for reliability in vehicle environments.
• High-speed digital signal transmission capability supporting data rates up to 5Mbps.
• Robust noise immunity characterized by a minimum common-mode transient immunity of 25kV/µs.
• Integrated push-pull output stage eliminates the need for external pull-up resistors.

Applications

• Automotive engine control unit (ECU) communication interfaces
• In-vehicle network gateways requiring galvanic isolation
• Industrial motor drive control circuits
• Power supply feedback loops in automotive systems

Procurement Notes

Verify the specific suffix (TPL,F) matches the required tape-and-reel packaging format for automated assembly. Confirm that the AEC-Q101 certification status aligns with your project's automotive quality requirements. Ensure the operating temperature range of -40°C to 105°C meets your environmental specifications. Cross-reference the 6-SO, 5-lead package dimensions with your PCB footprint design to ensure mechanical compatibility.

Selection Notes

Select this component when high-speed digital isolation is required within automotive applications. The push-pull output simplifies circuit design by removing external components typically needed for transistor outputs. Consider the 5Mbps data rate limit when designing for higher bandwidth signals. The wide supply voltage range allows flexibility in interfacing with various logic families. Verify that the 3750Vrms isolation rating satisfies safety standards for your specific application voltage levels.

Part Context

This part belongs to Toshiba's TLX series of automotive-grade optocouplers. The series is designed to meet the stringent reliability and performance demands of modern vehicle electronics. Unlike general-purpose optocouplers, these devices undergo rigorous testing to ensure stability under harsh automotive conditions, including vibration and extreme temperature fluctuations.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Users must consult official Toshiba resources or authorized distributors for qualified alternatives that match the specific pinout, electrical characteristics, and automotive qualification requirements.
