ZDM4306NTC

Overview

The ZDM4306NTC is a dual N-channel enhancement mode MOSFET manufactured by Diodes Incorporated, housed in an SM-8 (SOT-223) surface-mount package. It features a drain-source voltage rating of 60V and a continuous drain current of 2A at 25°C ambient temperature. The device supports a pulsed drain current of 15A and operates within a junction temperature range of -55°C to +150°C. Key electrical characteristics include a maximum static on-state resistance of 0.45Ω at VGS=5V and ID=1.5A, with a gate-source threshold voltage ranging from 1.3V to 3V. Total power dissipation reaches 3.0W when both dies are active equally.

Feature Summary

• Dual configuration integrating two independent N-channel enhancement mode MOSFETs within a single compact package for space-constrained designs.
• Logic-level gate drive capability with a low threshold voltage range suitable for direct interfacing with standard logic outputs.
• Robust thermal performance allowing up to 3.0W total power dissipation under typical PCB mounting conditions.

Applications

• DC-DC converter synchronous rectification stages
• Low-side switching applications in battery-powered devices
• Load switching circuits requiring dual channel isolation

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout compatibility and tape-and-reel specifications. Confirm that the component status remains active or qualified for new designs before finalizing procurement plans. Ensure the supplier provides traceable documentation matching the exact part number variant.

Selection Notes

Select this component for applications requiring dual isolated channels in a small footprint. Evaluate the 0.45Ω maximum RDS(on) at 5V gate drive to ensure it meets efficiency requirements for the target load current. Consider the 60V breakdown voltage margin relative to the system's maximum supply voltage and transient spikes.

Part Context

This component belongs to the ZDM series of dual N-channel MOSFETs from Diodes Incorporated. It shares the SM-8 package form factor with other variants in the family but differs in specific electrical ratings such as current handling and on-resistance. The 'NTC' suffix typically denotes the specific packaging and marking configuration.

Replacement Considerations

Direct substitutes must match the 60V/2A dual N-channel specification and SM-8 package. Verify pinout alignment between G1/S1/G2/S2/D1/D2 configurations. Check if alternative parts offer lower RDS(on) or higher current ratings while maintaining compatible gate threshold voltages.
