Product details

Overview

IPC80N04S403ATMA1 from Infineon Technologies is an AEC-Q101 qualified N-channel enhancement-mode MOSFET in PG-TDSON-8-23 package, rated for 40 V V_DS, 3.3 mΩ R_DS(on) at V_GS = 10 V and I_D = 40 A, with 100% single-pulse avalanche testing and MSL1 reflow compatibility - deployed in automotive DC-DC converters and motor control inverters.

For engineers reviewing the IPC80N04S403ATMA1 datasheet, IPC80N04S403ATMA1 pinout, IPC80N04S403ATMA1 application, or IPC80N04S403ATMA1 equivalent, key selection criteria include its 1.5 K/W R_thJC, 80 A continuous drain current at T_C = 25 °C, 215 mJ E_AS, 4400–5720 pF C_iss, and AEC qualification for under-hood power stages.

Technical Context

This OptiMOSTM-T2 MOSFET uses trench-gate silicon technology optimized for low conduction loss and fast switching in 12 V/24 V automotive systems. Its gate threshold voltage (2.0–4.0 V) ensures robust noise immunity, while the 5.6 V gate plateau voltage supports stable Miller region control during hard-switching.

The device integrates a co-packaged body diode with 0.9–1.3 V V_SD at 40 A and 45 ns t_rr, enabling synchronous rectification and freewheeling in half-bridge topologies. Thermal resistance of 1.5 K/W (junction-to-case) allows direct heatsink mounting without thermal interface material in constrained layouts.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	40 V - Maximum blocking voltage compatible with 12 V/24 V automotive battery rails and transient clamping up to ISO 7637-2 Pulse 5a.
R_DS(on)	3.3 mΩ @ V_GS = 10 V, I_D = 40 A - Enables <1.3 W conduction loss at 80 A peak in high-current motor phases.
I_D (cont.)	80 A @ T_C = 25 °C - Package-limited current rating suitable for compact 5–10 kW traction inverters and starter-generator modules.
E_AS	215 mJ - Confirmed single-pulse avalanche energy supporting inductive load switching without external snubbers.
C_iss	4400–5720 pF - Low input capacitance reduces gate drive power and enables >1 MHz switching in GaN-complementary gate drivers.
R_thJC	1.5 K/W - Allows direct thermal coupling to aluminum heatsinks, simplifying thermal design for under-hood ambient up to 125 °C.
t_r/t_f	7 ns / 13 ns - Fast edge rates minimize switching losses in hard-switched buck and half-bridge configurations.

Pinout & Package

PG-TDSON-8-23 is a thermally enhanced 8-pin exposed-pad surface-mount package with dual-source configuration for reduced parasitic inductance and improved current sharing. The exposed copper pad on the bottom provides primary thermal path to PCB heatsinking.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4, 5, 6	Source (S)	Common source terminals - internally paralleled to support high-current return paths and reduce layout inductance in H-bridge legs.
7	Gate (G)	Single gate input - low 55–71 nC total gate charge enables efficient driving with standard 1–2 A gate drivers.
8	Drain (D)	Drain connection tied to exposed pad - serves as main high-side switching node and thermal interface to heatsink.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive powertrain applications including engine control units and electric power steering modules.
100% avalanche tested	Each unit undergoes single-pulse E_AS stress test at 215 mJ - eliminates field failure risk from inductive kickback in motor drives.

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
IPB80N04S4-03	TO-263-7 package, identical die and electrical specs, higher R_thJC (2.0 K/W), no AOI feasibility	Preferred where through-hole mounting or manual rework is required; unsuitable for fine-pitch AOI lines	Select when board-level thermal mass compensates for higher junction-to-case resistance.
IRF8721TRPBF	40 V, 7.8 mΩ R_DS(on), non-AEC, SO-8 package, lower E_AS (120 mJ), no avalanche testing	Acceptable for non-safety-critical consumer or industrial DC-DC, not for automotive powertrain	Choose only for cost-sensitive non-automotive designs where AEC qualification and 215 mJ E_AS are not required.

Compared with IPB80N04S4-03 and IRF8721TRPBF, IPC80N04S403ATMA1 uniquely combines AEC-Q101 compliance, MSL1 reflow capability, AOI readiness, and 1.5 K/W thermal resistance - making it the only option qualified for volume production in safety-critical 12 V/48 V automotive power stages.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The absolute maximum junction temperature is +175 °C, but Infineon specifies that operation above +150 °C is limited to 200 hours over the device lifetime. For sustained reliability in automotive applications, thermal design must ensure T_j remains ≤150 °C under worst-case ambient and power dissipation conditions.

Does this MOSFET require a negative gate voltage for safe turn-off in high-dv/dt environments?

No - the device has a gate threshold voltage range of 2.0–4.0 V and is designed for 0–10 V gate drive. A negative gate voltage is not required; however, a gate resistor of ≤3.5 Ω and local bypass capacitance are recommended to suppress ringing during fast switching in high-noise automotive environments.

Can IPC80N04S403ATMA1 be used in parallel configurations?

Yes - its positive temperature coefficient for R_DS(on) (shown in Fig. 6) ensures inherent current sharing. Parallel operation requires matched gate drive routing, symmetrical PCB layout, and individual gate resistors to prevent oscillation. Derating to 70% of total rated current per device is advised for thermal margin.

Is the body diode suitable for continuous freewheeling in synchronous rectification?

Yes - the integrated body diode is rated for 80 A continuous forward current (I_S) and 320 A pulsed current (I_S,pulse). With 0.9–1.3 V V_SD and 45 ns t_rr, it supports synchronous rectification in buck converters up to 500 kHz, though external Schottky diodes may be preferred for ultra-low-loss 12 V output stages.
