ZDT6757TC

Overview

The ZDT6757TC is a complementary medium power transistor array manufactured by Diodes Incorporated, housed in an SM-8 (SOT-223) package. It integrates one NPN and one PNP bipolar junction transistor within a single surface-mount device. The NPN section supports a continuous collector current of 0.5A with a collector-emitter breakdown voltage of 300V. The PNP section mirrors these ratings with -0.5A and -300V respectively. Both transistors feature a transition frequency of 30MHz and operate across a temperature range of -55°C to +150°C.

Feature Summary

• Complementary NPN/PNP configuration for push-pull or bridge applications
• High voltage capability suitable for medium power switching
• Surface-mount SM-8 package design for space-constrained layouts

Applications

• Push-pull output stages in audio amplifiers
• Motor driver circuits requiring complementary control
• Power supply output stages

Procurement Notes

Verify the specific suffix 'TC' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status directly from the latest datasheet revision. Ensure the ordering part number matches the exact electrical characteristics required for the target application circuit.

Selection Notes

Select this component when a matched complementary pair is required for high-voltage switching applications. The 300V rating distinguishes it from lower-voltage general-purpose arrays. Consider the thermal resistance values when designing heat dissipation strategies for the PCB copper area.

Part Context

This device belongs to the ZDT series of complementary medium power transistors. It serves as a discrete alternative to integrated power ICs, offering flexibility in custom amplifier and driver designs. The SM-8 package provides a compact footprint compared to traditional through-hole alternatives like TO-220.

Replacement Considerations

Check for direct pin-compatible replacements such as the FZT6757 or similar complementary pairs from other manufacturers. Verify that substitute parts meet the 300V breakdown and 0.5A current requirements.
