TLP701H(GEHC,F)

Overview

The TLP701H(GEHC,F) is a high-speed logic output optocoupler manufactured by Toshiba Semiconductor and Storage. It features a GaAlAs LED coupled to a high-speed photodiode array and an integrated output IC, providing a push-pull or open-collector configuration depending on the specific suffix variant. The device offers a high common-mode rejection ratio (CMTI) of up to 50 kV/µs, ensuring reliable signal transmission in noisy environments. Key electrical parameters include a peak output current of 200 mA and a propagation delay typically around 300 ns. It operates with a supply voltage range of 4.5 V to 5.5 V for the output side and supports isolation voltages up to 5000 Vrms.

Feature Summary

• High-speed data transmission capability suitable for communication interfaces
• Integrated high-gain output stage for direct driving of TTL and CMOS loads
• High common-mode noise immunity to prevent false triggering
• Compact surface-mount package design for space-constrained applications

Applications

• Industrial automation control systems
• Communication interface circuits such as RS-485 and CAN bus
• Power supply feedback loops
• Microcontroller input/output isolation

Procurement Notes

Verify the exact suffix code (e.g., GEHC, F) against the datasheet to confirm pinout and electrical characteristics, as variations exist within the TLP701H family. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may fluctuate. Ensure the selected variant matches the required isolation voltage and output configuration for the specific circuit design.

Selection Notes

Select this component when high-speed digital isolation is required between microcontrollers and power stages. Consider the CMTI rating if operating in high-noise industrial environments. Compare propagation delay specifications against system timing requirements. Ensure the output current capability meets the load drive needs without external buffering.

Part Context

The TLP701H series belongs to Toshiba's high-speed optocoupler lineup, designed for robust signal integrity in digital circuits. It serves as a critical interface component for isolating low-voltage logic from higher-voltage power domains. The series is widely used in applications demanding fast response times and high reliability, distinguishing it from standard general-purpose optocouplers.

Replacement Considerations

Publicly confirmed substitute part numbers are not explicitly listed in the provided source material. Engineers should consult official Toshiba documentation or distributor cross-reference tools for verified alternatives that match the specific speed, isolation, and package requirements.
