TLP5772H(E

Overview

The TLP5772H(E) is a single-channel optically isolated gate driver manufactured by Toshiba Semiconductor and Storage. It features a push-pull output capable of sourcing and sinking 2.5 A, designed for driving IGBTs and MOSFETs. The device provides 5000 Vrms isolation voltage and operates within a temperature range of -40°C to +125°C. Key electrical parameters include a maximum propagation delay of 150 ns, typical rise and fall times of 56 ns and 25 ns respectively, and a minimum common-mode transient immunity of 35 kV/µs. It accepts a DC input with a maximum forward current of 8 mA and a typical forward voltage of 1.65 V. The supply voltage range is 10 V to 30 V, and it is housed in a 6-SOIC package.

Feature Summary

• High peak output current capability of +/- 2.5 A for direct gate drive applications
• Enhanced noise immunity with 35 kV/µs minimum common-mode transient rejection
• Wide operating temperature range supporting high-temperature industrial environments
• Compact surface-mount packaging suitable for space-constrained power circuits

Applications

• Insulated Gate Bipolar Transistor (IGBT) gate driving
• Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) switching control
• Induction heating systems and cooktops
• Switching power supplies requiring galvanic isolation

Procurement Notes

Verify the specific suffix code against the manufacturer's official datasheet to confirm pinout compatibility and packaging type. Ensure the selected variant matches the required thermal management specifications for the intended application environment. Cross-reference ordering codes with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status if restricted substances are a project constraint.

Selection Notes

Select this component when high-speed switching with robust noise immunity is required for power devices. The 2.5 A output current supports medium-power IGBT and MOSFET gates without external buffering. Consider the 5000 Vrms isolation rating for safety-critical designs. Evaluate the 150 ns propagation delay against system timing requirements. Compare against lower-current variants if load demands are reduced.

Part Context

This part belongs to the TLP5772H family of optocouplers from Toshiba. It is specifically engineered as a gate drive coupler rather than a standard logic isolator. The series includes variants with different packaging options such as tube, reel, and cut tape configurations. It serves as a bridge between low-voltage control logic and high-voltage power stages in modern power electronics.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pin-to-pin compatibility and electrical parameter equivalence before considering alternative manufacturers.
