Additional Information:

The PMGD780SN from Nexperia is a dual N-channel Trench MOSFET that balances compactness with efficiency, making it a suitable choice for a variety of switching applications. Not only does it come in a small SOT363 package, but it also offers a high drain-source voltage of 60V, ensuring reliable performance in low-power circuits. Moreover, with a maximum continuous drain current of 0.49A, it effectively handles moderate power loads. In addition, its low on-state resistance, measuring 920 mΩ at 10V gate drive, allows for efficient operation with minimal power loss. Furthermore, the MOSFET boasts a gate-source voltage rating of ±20V, which enhances its versatility across different applications. Despite these advantages, it is important to note that this component is currently Not Recommended for New Designs (NRND), meaning engineers should consider alternative solutions for long-term product development.

Nevertheless, for those still using the PMGD780SN, it remains a viable choice, particularly in existing designs that require fast switching and low capacitance characteristics. For example, its total gate charge of just 1.05 nC at 10V gate drive ensures rapid response times, making it ideal for driver circuits and portable appliances. Additionally, its low input capacitance of 23 pF contributes to efficient switching behavior, which is particularly useful in battery-operated devices. That being said, since Nexperia now recommends the NX7002BKS as a replacement, engineers designing new systems should explore that option instead. Overall, while the PMGD780SN still functions effectively, its phase-out status encourages designers to transition toward more up-to-date components for better long-term support and availability.
