ZHB6790TA

Overview

The ZHB6790TA is a bipolar transistor H-bridge array manufactured by Diodes Incorporated, housed in an SM-8 surface-mount package. It integrates two NPN and two PNP transistors to facilitate bridge configurations. The device supports continuous collector currents of up to 2A with maximum collector-emitter voltages of ±40V for NPN and PNP sections respectively. Total power dissipation reaches 1.25W for single transistors and 2W for dual pairs at +25°C ambient temperature. Transition frequencies are rated at 100MHz for PNP and 150MHz for NPN devices.

Feature Summary

• Integrated H-Bridge topology combining complementary NPN and PNP transistors
• Low on-state losses and low drive requirements
• Compact molded plastic package with UL flammability rating 94V-0

Applications

• Automotive applications requiring specific change control (AEC-Q100/101/104/200 qualified parts available upon request)
• Motor driver circuits utilizing standard H-Bridge topologies
• Actuator driver systems

Procurement Notes

Verify the exact ordering suffix against the manufacturer's current catalog before procurement. Confirm that the component meets all necessary automotive qualification standards if required for the application. Ensure compliance with RoHS3 specifications and check for any recent product change notices or end-of-life announcements prior to finalizing orders.

Selection Notes

Evaluate thermal resistance values based on PCB copper area, as power dissipation capabilities vary significantly between full copper and minimal footprint layouts. Consider switching times and transition frequencies when designing for high-speed operation. Verify base drive requirements to ensure adequate saturation voltage performance under expected load conditions.
