Key Features
- Ultra-low Rds(on) of 5.8 mΩ max at Vgs = 10 V (and ~7.5 mΩ at Vgs = 4.5 V) for high-current synchronous-rectifier and OR-ing applications
- 60 V VDS rating with 100 A continuous drain current and 224 mJ avalanche energy headroom for inductive switching loads
- Logic-level threshold and 4.5 V-rated gate let modern MCUs and gate drivers control the device without level shifters
- NexFET silicon technology delivers a low gate charge / low Qg × Rds(on) figure-of-merit, reducing both switching and conduction losses in 12 V/24 V converters
- 5 mm × 6 mm SON-8 (DDPAK / TO-Less style) with exposed thermal pad, AEC-Q101-style production grade, RoHS / Pb-free compliant
Applications
Used in 12 V/24 V brushless-DC motor drives, e-bike and power-tool inverters, telecom/server hot-swap controllers, OR-ing FETs for redundant power supplies, and synchronous-rectifier stages of mid-power buck converters. Also fits load-switch and reverse-polarity-protection roles in 24 V industrial backplanes thanks to the 60 V drain-source rating.

Frequently Asked Questions
What is the Rds(on) and gate-drive voltage of CSD18531Q5A?
CSD18531Q5A has a maximum Rds(on) of 5.8 mΩ at Vgs = 10 V and approximately 7.5 mΩ at Vgs = 4.5 V (logic level). Threshold voltage is 1.0 V to 2.5 V, so the MOSFET fully enhances with any 5 V or 3.3 V driver capable of sourcing the gate-charge current at the desired switching frequency.
Is CSD18531Q5A avalanche-rated and what is its package?
Yes. CSD18531Q5A is avalanche-rated to 224 mJ (Eas) — relevant for clamping inductor recirculation in motor and solenoid applications without an external freewheel diode. The package is a 5 mm × 6 mm 8-pin SON (Q5A footprint) with exposed thermal pad on the bottom; MSL handling is required during reflow.
Is CSD18531Q5A RoHS compliant and what is its drain-source voltage rating?
Yes, CSD18531Q5A is RoHS compliant and Pb-free. Drain-source breakdown voltage (BVDSS) is 60 V minimum, making it well-matched for 12 V to 48 V power architectures with comfortable transient headroom for inductive spikes and load-dump events.
