ZDT6758TC

Overview

The ZDT6758TC is a surface-mount bipolar junction transistor (BJT) array manufactured by Diodes Incorporated. It integrates one NPN and one PNP transistor within an SM-8 package. The device features a maximum collector-emitter breakdown voltage of 400V and a continuous collector current rating of 500mA. Power dissipation is rated at 2.75W, with a transition frequency of 50MHz. The component operates across a temperature range from -55°C to +150°C.

Feature Summary

• Integrates complementary NPN and PNP transistors in a single surface-mount package
• Supports high-voltage applications with a 400V collector-emitter breakdown rating
• Designed for thermal stability with a maximum power dissipation of 2.75W

Applications

• High-voltage switching circuits
• Complementary amplifier stages
• Power management modules requiring integrated dual-transistor solutions

Procurement Notes

Verify the specific manufacturer datasheet for electrical tolerances and thermal characteristics before integration. Confirm that the SM-8 footprint matches the target PCB layout. Ensure compliance with relevant environmental standards such as RoHS if required by the final product specifications. Review the official documentation for handling precautions related to surface-mount assembly processes.

Selection Notes

Select this component when a compact solution for high-voltage complementary switching is required. The 400V rating distinguishes it from standard low-voltage logic transistors. Consider the 500mA current limit for load requirements. The wide operating temperature range supports use in demanding industrial or automotive environments where thermal resilience is critical for long-term reliability.

Part Context

This part belongs to the ZDT series of dual transistor arrays produced by Diodes Incorporated. These components are designed to replace discrete transistor pairs, saving board space and simplifying assembly. The SM-8 package provides efficient heat dissipation relative to its size. This specific model represents a high-voltage variant within the broader family of complementary BJT arrays.

Replacement Considerations

Public sources indicate the ZDT6758TC is obsolete. Verify availability of direct substitutes through official manufacturer channels. Cross-reference pinouts and electrical ratings carefully when selecting alternative components.
