Product details

Overview

DMNH4005SPSWQ-13 from Diodes Incorporated is a 40V N-channel automotive-grade MOSFET in PowerDI5060-8/SWP package, rated for 80A continuous drain current at TC = +25°C, with R_DS(ON) = 4.0 mΩ @ V_GS = 10V and qualified to AEC-Q101 for engine management and DC-DC converter applications.

For engineers reviewing the DMNH4005SPSWQ-13 datasheet, DMNH4005SPSWQ-13 pinout, DMNH4005SPSWQ-13 application, or DMNH4005SPSWQ-13 equivalent, this part supports high-temperature operation up to +175°C, delivers low switching loss via Q_g = 48 nC (V_GS = 10V), and features 100% unclamped inductive switching validation - critical for automotive power stage reliability.

Technical Context

This MOSFET employs a trench-gate silicon process optimized for low R_DS(ON) and fast switching in high-current automotive power stages. Its internal structure integrates a robust body diode with t_RR = 29 ns and Q_RR = 24 nC under IF = 15A, di/dt = 100 A/µs conditions.

The device operates with V_GS(TH) = 1–3 V, enabling gate drive compatibility with standard 3.3V/5V logic controllers, and maintains stable on-resistance across -55°C to +175°C junction temperature range - normalized R_DS(ON) variation ≤1.6× at T_J = +175°C vs. 25°C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	40 V - Maximum blocking voltage for 12V/24V automotive battery rail protection and DC-DC primary-side switching
R_DS(ON) max	4.0 mΩ @ V_GS = 10V - Enables <1.6 W conduction loss at 20A, reducing thermal load in compact power modules
I_D continuous	80 A @ T_C = +25°C - Supports high-current motor drivers and starter solenoid control without external heatsinking
Q_g	48 nC @ V_GS = 10V - Allows efficient 100–200 kHz PWM operation with minimal gate driver power demand
T_J max	+175°C - Certified for under-hood environments including engine bay and transmission control units
E_AS	445 mJ - Withstands repetitive inductive energy spikes in relay and solenoid driving without failure
R_θJC	0.9 °C/W - Enables direct thermal coupling to PCB copper planes or metal-core substrates for passive cooling

Pinout & Package

DC-DC Converters

Start-Stop Battery Management

Use Scenario: Primary-side synchronous rectifier in 48V-to-12V bidirectional buck-boost converter for mild hybrid vehicles.

IC Role / Device Role / Timing Role: High-efficiency power switch operating at 200 kHz with low Q_g and fast t_F = 4.9 ns to minimize switching loss.

Use Value: C_iss = 2847 pF and Cr_ss = 243 pF enable clean zero-voltage switching (ZVS) transition in resonant topologies.

Use Scenario: Load dump protection and battery disconnect switch in start-stop control units managing AGM battery charge cycles.

IC Role / Device Role / Timing Role: Robust main power switch handling 80A cranking surges and absorbing ISO 7637-2 pulse 5a transients.

Use Value: E_AS = 445 mJ and V_DSS = 40V exceed ISO 16750-2 requirements for 35V load dump clamping with safety margin.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel automotive MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXTQ48N25P	250V V_DSS, 48A I_D, TO-220AB package, R_DS(ON) = 45 mΩ - higher voltage rating but 11× higher on-resistance	Designed for industrial 200V+ inverters; unsuitable for 12V/48V automotive low-V_DS optimization	Select only if system requires >100V blocking and can tolerate higher conduction loss and larger footprint
STL220N4F7AG	40V V_DSS, 220A I_D, PowerFLAT 5x6 package, R_DS(ON) = 0.75 mΩ - lower R_DS(ON) but no AEC-Q101 certification	Targeted at consumer/commercial power tools; lacks PPAP documentation and IATF 16949 traceability	Acceptable for non-safety-critical prototypes; not approved for Tier-1 automotive production without requalification

Compared with IXTQ48N25P and STL220N4F7AG, DMNH4005SPSWQ-13 uniquely balances AEC-Q101 compliance, 4.0 mΩ R_DS(ON), and PowerDI5060-8's ultra-low profile - making it the only option certified for volume production in space- and thermal-constrained automotive power stages.

FAQ

What is the maximum pulsed drain current rating for DMNH4005SPSWQ-13?

The pulsed drain current (I_DM) is rated at 90 A for 10 µs pulses with 1% duty cycle. This rating assumes junction temperature remains ≤+25°C and accounts for short-duration thermal inertia - it is not sustainable under continuous operation or elevated ambient conditions.

Does DMNH4005SPSWQ-13 include an integrated Schottky body diode?

No - it uses a standard silicon body diode with V_SD = 1.2 V at I_S = 1 A and t_RR = 29 ns. The diode is intrinsic to the MOSFET structure and not a separate Schottky element; its recovery characteristics are specified per JEDEC JESD24-11 test conditions.

Can DMNH4005SPSWQ-13 be used in synchronous rectification topologies?

Yes - its low R_DS(ON) (4.0 mΩ), fast t_F = 4.9 ns, and controlled Q_gd/Q_gs ratio support efficient synchronous rectification in buck, boost, and LLC converters up to 200 kHz, provided gate drive timing avoids shoot-through.

What is the moisture sensitivity level (MSL) for the PowerDI5060-8/SWP package?

The package has MSL Level 1 per J-STD-020, meaning it is not moisture-sensitive and may be stored indefinitely at ≤30°C/85% RH without baking prior to reflow soldering - eliminating MSL handling constraints in SMT assembly lines.
