ZHB6790TC

Overview

The ZHB6790TC is a bipolar transistor H-bridge integrated circuit manufactured by Diodes Incorporated, housed in an SM-8 surface-mount package. It integrates four discrete transistors (two NPN and two PNP) into a single compact component. The device supports continuous collector currents of up to 2A per transistor and operates with supply voltages up to 40V. Key electrical parameters include a collector-emitter breakdown voltage of 40V for NPNs and -40V for PNPs, and a peak pulse current rating of 6A. The unit features low on-state losses and minimal drive requirements, making it suitable for efficient motor control applications.

Feature Summary

• Integrated H-Bridge topology combining NPN and PNP transistors
• Low on-state power dissipation characteristics
• Reduced external drive signal requirements
• Compact SM-8 molded plastic package

Applications

• Automotive motor driver circuits
• DC motor speed control systems
• Actuator driving interfaces

Procurement Notes

Verify the specific suffix 'TC' against the official datasheet to confirm exact ordering details, as standard listings may reference the base model ZHB6790. Confirm that the procurement channel provides genuine components from authorized distributors to ensure compliance with quality standards. Check for any specific handling or storage requirements associated with the SM-8 package before placing orders.

Selection Notes

Select this component when a compact solution for driving DC motors or actuators is required. Ensure the application voltage does not exceed the 40V collector-emitter limit. Verify that the PCB layout can accommodate the thermal dissipation needs of the SM-8 package, particularly if multiple transistors are active simultaneously. Consider the transition frequency limits for high-speed switching requirements.

Part Context

The ZHB6790 series represents a specialized class of complex transistor arrays designed specifically for half-H and full-H bridge configurations. Unlike discrete transistor solutions, this integrated approach reduces board space and simplifies schematic design. It is part of Diodes Incorporated's portfolio aimed at automotive and industrial motor control sectors where reliability and size constraints are critical.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Diodes Incorporated directly for recommended alternatives or updated product lines, as the datasheet explicitly states the ZHB6790 is not recommended for new designs.
