IAUCN04S7N019DATMA1 Overview
A dual MOSFET array is a small outline surface-mount module that integrates two identical N-channel MOSFET dies in a common package, sharing the drain thermal pad but providing independent gate/source control on each device. Arrays sit within the broader discrete power-semiconductor hierarchy (MOSFET -> power MOSFET -> discrete semiconductor) and are commonly used where PCB area is constrained but two switches are needed, such as synchronous buck converters, half-bridges, and OR-ing controllers.
Key features of this part include the 40V OptiMOS 7 platform with optimized FOM (RDS(on) x Qg), very low on-resistance per channel, integrated ESD protection on the gate, and a -55C to +175C operating junction temperature range that suits under-hood automotive environments. The 1.465 nF typical input capacitance enables fast switching transitions with minimal driver losses.
Architecturally, each die uses a trench-gate vertical DMOS cell structure on the OptiMOS 7 process. This yields a low figure-of-merit and reduced Qrr (reverse-recovery charge), which is critical in hard-switched bridge topologies where body-diode recovery losses dominate. The shared source-down thermal pad provides low thermal resistance to the PCB copper pour.
Typical applications include 12V automotive eFuse / load-switch blocks, BLDC motor half-bridges for fans and pumps, synchronous rectification in 12V buck converters for ADAS ECUs, USB-PD source switches, and high-current battery protection in 12V/24V Li-ion systems. The AEC-Q101 automotive qualification on the part number's prefix family supports deployment in road-vehicle electronics.
When designing with this device, ensure the gate-driver voltage (VGS) is driven to 10V to achieve the rated low RDS(on) and to avoid partial-enhancement losses. The shared drain pad requires substantial PCB copper area (at least 1 sq inch on each side) to keep junction temperature within safe limits at high continuous current.

Typical Applications
IAUCN04S7N019DATMA1 is suitable for 6 applications: 12V Automotive eFuse / Load Switch, BLDC Motor Half-Bridge (Fan / Pump), Synchronous Rectification in 12V Buck Converters, USB-PD Source / Sink Power Switch, High-Current Battery Protection (12V/24V Li-ion), Server / Datacenter 12V Hot-Swap OR-ing.
12V Automotive eFuse / Load Switch
The IAUCN04S7N019DATMA1 fits 12V automotive eFuse blocks where its 40V VDS rating provides 28V load-dump transient headroom and 160A continuous current handles high-power body-domain loads. Its 1.465nF Ciss enables fast <1us turn-off for short-circuit protection. Placed as a high-side switch with a gate driver like 1ED020I12B2XUMA1, the 019 grade minimizes I^2R conduction loss. AEC-Q101 qualification supports deployment in road-vehicle ECUs.
Recommended
BLDC Motor Half-Bridge (Fan / Pump)
The IAUCN04S7N019DATMA1 fits BLDC fan and pump half-bridges where its dual N-channel configuration provides the high-side and low-side switches of one phase. The 96W (Tc) power dissipation keeps junction rise small at typical 5-10A motor currents, and the 160A rating supports stall-current transients. Paired with IRSM808-105MH module or BTS70402EPGXUMA1, it implements a compact 12V/24V motor drive. OptiMOS 7 low Qrr reduces dead-time loss.
Recommended
Synchronous Rectification in 12V Buck Converters
The IAUCN04S7N019DATMA1 fits the synchronous-rectifier (low-side) position of 12V-input buck converters for ADAS ECUs and infotainment rails. Its 40V VDS rating supports 12V nominal input plus transients, and the 019 RDS(on) grade minimizes conduction loss at 20-30A load currents. The 1.465nF Ciss and low Qg of OptiMOS 7 reduce driver loss at 500kHz switching. Paired with IPW60R037P7XKSA1 on the high-side, it forms a 600V-class high-density buck.
Recommended
USB-PD Source / Sink Power Switch
The IAUCN04S7N019DATMA1 fits USB-PD source and sink power-switch paths where 20V/5A (100W) capability is required. The 40V VDS rating covers the 20V PD range with margin, and the dual-channel configuration allows VBUS and CC-line protection in one footprint. The AEC-Q101 automotive qualification enables in-vehicle USB charging. Used with IPB60R280P7ATMA1 for the AC-side front end, it forms a complete PD source solution.
Recommended
High-Current Battery Protection (12V/24V Li-ion)
The IAUCN04S7N019DATMA1 fits 12V/24V Li-ion battery-pack protection FETs where 160A continuous rating handles motor-start inrush. The 40V VDS covers 4S Li-ion (16.8V max) plus transient spike margin, and the dual-die array fits one direction of the bidirectional H-bridge disconnect. Paired with ISC015N06NM5ATMA1 as a redundant disconnect, it provides two-level pack protection. The 175C Tj rating supports hot-pack environments.
Recommended
Server / Datacenter 12V Hot-Swap OR-ing
The IAUCN04S7N019DATMA1 fits 12V hot-swap and OR-ing blocks in server and datacenter power shelves where its 160A continuous current handles a full PSU rail. The 40V VDS comfortably covers 12V with margin for ringing, and the dual-die array supports back-to-back OR-ing FET topology. The OptiMOS 7 low Qrr eliminates body-diode reverse-recovery induced cross-conduction. AEC-Q101 automotive grade adds ruggedness for harsh server-room thermal envelopes.

Design Notes
At continuous 160A drain current, the IAUCN04S7N019DATMA1 dissipates up to 96W (Tc). Estimated: with 2 oz copper pour on at least 1 sq inch of PCB around the PG-TDSON-8-60 thermal pad, the junction-to-ambient thermal resistance is approximately 35 C/W, yielding a 70C junction rise at full load. For 80% derated operation, use 2 sq inches of copper on each side of the pad.
The PG-TDSON-8-60 SuperSO8 package shares its drain thermal pad between both MOSFET dies. Place at least 8 thermal vias (0.3mm drill, 1.0mm pitch) directly under the exposed pad, with the top-side copper flood at least 1 sq inch. Keep high-current source traces wide (>=2mm per 5A) to avoid copper-heating loss.
Route the gate-drive traces as short as possible and away from the drain switching node to minimize gate-loop inductance. Use a gate-source resistor of 10-100k ohm to prevent false turn-on from dV/dt coupling. Keep the gate-driver within 5mm of the package pins to limit ringing and dv/dt induced shoot-through.
Do not drive the gate below 10V (or 4.5V for L-suffix parts) to achieve datasheet RDS(on). Driving the IAUCN04S7N019DATMA1 gate at 5V will not reach the rated 1.9 mOhm RDS(on) and can double conduction loss. Also, ensure the 40V VDS rating is not exceeded during load-dump transients - add a TVS clamp if the design sees >28V transients.
