Frequently Asked Questions
What is the maximum drain current and on-resistance of the CSD16321Q5?
The CSD16321Q5 supports a maximum continuous drain current (ID) of 100A and features an ultra-low drain-source on-resistance (RDS(on)) of 3.5mΩ maximum. These specifications make it one of the most efficient 25V N-Channel MOSFETs available for high-current power conversion applications.
What applications is the CSD16321Q5 best suited for?
The CSD16321Q5 is ideal for synchronous DC-DC buck converters, server and telecom power supplies, point-of-load regulators, battery management systems, and automotive power modules. Its 25V rating, 100A current capacity, and 3.5mΩ RDS(on) make it especially effective in 12V and 24V power rail designs requiring high efficiency.
Is the CSD16321Q5 avalanche rated and what does that mean?
Yes, the CSD16321Q5 is avalanche rated with an avalanche energy rating (Eas) of 218mJ. Avalanche rating means the MOSFET can safely absorb energy during unclamped inductive switching events, protecting the device from damage caused by voltage spikes that exceed the breakdown voltage — an important reliability feature for motor drives and switching power supplies.
Where can I buy the CSD16321Q5 and what is the price?
The CSD16321Q5 is available from authorized distributors worldwide. The unit price starts from approximately $0.46 depending on order quantity. FindMyChip provides real-time stock and pricing information, and you can submit a quote request directly for bulk purchases with fast worldwide shipping.
