Product details

Overview

IPB100N04S204ATMA1 from Infineon Technologies is an N-channel enhancement-mode automotive-qualified power MOSFET in PG-TO263-3-2 package, rated for 40 V V_DS, 100 A continuous drain current at T_C = 25 °C, and ultra-low 3.3 mΩ max R_DS(on) at V_GS = 10 V. It is 100% avalanche tested, AEC-Q101 qualified, and operates up to 175 °C - deployed in high-current DC-DC converters and motor control stages of electric power steering (EPS) systems.

For engineers reviewing the IPB100N04S204ATMA1 datasheet, IPB100N04S204ATMA1 pinout, IPB100N04S204ATMA1 application, or IPB100N04S204ATMA1 equivalent, key selection criteria include its 0.5 K/W junction-to-case thermal resistance, 125–172 nC total gate charge, 810 mJ single-pulse avalanche energy, and SMD-compatible TO263 footprint for high-power density board layouts.

Technical Context

This OptiMOS® device uses trench-gate superjunction technology optimized for low conduction and switching losses in 12 V/24 V automotive and industrial power stages. Its gate threshold voltage (2.1–4.0 V) enables robust drive with standard 10 V logic-level gate drivers, while the 5300 pF input capacitance and 580 pF reverse transfer capacitance support predictable turn-on/turn-off timing under 2.2 Ω gate resistance.

The integrated body diode exhibits 0.9–1.3 V forward voltage at 80 A and 66–80 ns reverse recovery time, enabling synchronous rectification and freewheeling operation without external diodes in half-bridge configurations. Thermal design leverages direct die-to-case conduction via copper tab, validated for 300 W dissipation at T_C = 25 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	40 V - Maximum blocking voltage compatible with 24 V nominal automotive systems and 36 V transient surges.
R_DS(on) max	3.3 mΩ at V_GS = 10 V, I_D = 80 A - Enables <1.5 W conduction loss at 100 A, critical for thermally constrained EPS modules.
I_D cont	100 A at T_C = 25 °C - Supported by bondwire-limited current rating and 0.5 K/W R_thJC for direct heatsink mounting.
E_AS	810 mJ (I_D = 80 A) - Withstands inductive kickback in motor phase-legs without external snubbers.
Q_g	125–172 nC - Determines gate driver power requirement; ~1.7 W avg. drive loss at 100 kHz switching with 10 V swing.
t_r/t_f	46 ns / 33 ns - Enables fast switching with minimal overlap loss in hard-switched topologies.
V_SD	0.9–1.3 V at I_F = 80 A - Low forward drop reduces freewheeling loss versus discrete Schottky solutions.

Pinout & Package

IPB100N04S204ATMA1 is housed in PG-TO263-3-2 (D²PAK), a surface-mount power package with isolated gate pad, large copper drain tab for thermal and electrical conduction, and gull-wing leads for reflow compatibility. The drain tab is electrically connected to Pin 2 (Drain), enabling direct PCB copper pour attachment.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Source terminal	Low-side reference node; connects to ground or current-sense resistor in high-side switch configurations.
Pin 2 (Drain)	Drain terminal	High-current output node; electrically tied to exposed copper tab for thermal path and low-inductance power routing.
Pin 3 (Gate)	Control input	High-impedance MOSFET gate requiring <172 nC charge; sensitive to ESD and ringing - needs local RC snubber or gate resistor.

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive under-hood use including temperature cycling, humidity bias, and mechanical shock per JESD22 standards.
100% unclamped inductive switching (UIS) test	Guarantees robustness against inductive load transients without derating - eliminates need for pre-screening in safety-critical EPS designs.
MSL1 rating (260 °C peak reflow)	Enables single-pass lead-free reflow assembly without moisture-related popcorn failure or delamination.
Green (lead-free) package	Complies with RoHS Directive 2011/65/EU and ELV requirements for end-of-life vehicle recycling.
Optimized R_DS(on) × Q_g figure of merit	~415 mΩ·nC - balances conduction and switching loss for 20–100 kHz motor drive applications.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel 40 V power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPP100N04S2-04	Same die, PG-TO220-3-1 through-hole package; R_DS(on) max = 3.6 mΩ; R_thJA = 62 K/W (leaded)	Used where manual assembly, serviceability, or vertical heatsink mounting is required - not suitable for automated SMT lines.	Select when board-level rework or field replacement is prioritized over power density.
IRFB7546PBF	40 V, 110 A, R_DS(on) max = 3.2 mΩ; higher Q_g (190 nC); non-AEC-Q101; TO-220AB package	Targeted at industrial UPS and telecom power supplies - lacks automotive qualification and MSL1 reflow rating.	Choose only for cost-sensitive non-automotive applications where AEC-Q101 and lead-free compliance are not mandated.

Compared with IPP100N04S2-04 and IRFB7546PBF, IPB100N04S204ATMA1 uniquely combines SMD packaging, AEC-Q101 qualification, and 3.3 mΩ R_DS(on) - making it the sole option for automated production of thermally demanding automotive power stages requiring zero reflow risk and full automotive traceability.

FAQ

What is the maximum allowable gate-source voltage for IPB100N04S204ATMA1?

The absolute maximum gate-source voltage is ±20 V, qualified at both -20 V and +20 V per datasheet Rev. 1.0. Operation beyond this range risks permanent gate oxide damage. For reliable 10 V logic-level drive, a 12 V gate supply with 100 ns overvoltage margin is recommended - no external Zener clamping is needed if driver output is rail-limited.

Does IPB100N04S204ATMA1 require a gate resistor, and what value is recommended?

Yes - a series gate resistor is mandatory to dampen ringing and limit peak gate current. Based on 172 nC Q_g and typical 10 V driver rise time, a 2.2 Ω resistor is specified in the datasheet for 100 A switching. For 50 kHz EPS applications, 4.7 Ω improves EMI without compromising thermal performance, verified via gate waveform measurements in ANPS071E.

Can IPB100N04S204ATMA1 be used in parallel configurations?

Yes - its positive temperature coefficient of R_DS(on) (see Fig. 9) ensures inherent current sharing above 100 °C junction temperature. Successful parallel operation requires matched layout: identical gate trace lengths, Kelvin source connections, and shared thermal interface to a common heatsink. Derating to 80 A per device is advised for >150 °C ambient.

Is the drain tab electrically isolated from the PCB copper pour?

No - the exposed drain tab is electrically connected to Pin 2 (Drain) and must be soldered directly to a dedicated, non-grounded copper pour. This pour serves as both thermal path and high-current return. Isolation is achieved only by maintaining minimum creepage/clearance distances (≥1.5 mm) to adjacent traces or planes per IPC-2221B Class B requirements.
