Product details

Overview

IPC70N04S5L4R2ATMA1 from Infineon Technologies is an AEC-Q101 qualified N-channel logic-level OptiMOS™-5 power MOSFET with 40 V V_DS, 4.2 mΩ R_DS(on) at V_GS = 10 V, 70 A continuous drain current at T_C = 25 °C, and 175 °C maximum junction temperature - deployed in automotive DC-DC converters, motor control stages, and high-efficiency body electronics.

For engineers reviewing the IPC70N04S5L4R2ATMA1 datasheet, IPC70N04S5L4R2ATMA1 pinout, IPC70N04S5L4R2ATMA1 application, or IPC70N04S5L4R2ATMA1 equivalent, key selection criteria include logic-level gate drive compatibility (V_GS(th) = 1.2–2.0 V), avalanche ruggedness (E_AS = 32 mJ), thermal resistance (R_thJC = 3.0 K/W), and PG-TDSON-8-33 package suitability for high-power density PCB layouts.

Technical Context

This device implements a trench-based silicon MOSFET architecture optimized for low conduction and switching losses in 12 V automotive systems. Its logic-level gate enables direct drive from microcontrollers or ASICs without level-shifting, while its 100% avalanche-tested construction ensures robustness against inductive load transients.

The PG-TDSON-8-33 package features exposed drain pad for low-inductance, high-current routing and thermal path optimization. Dynamic parameters - including C_iss = 1230–1600 pF, Q_g = 22–30 nC, and t_r/t_f ≤ 2 ns/6 ns - support high-frequency PWM operation up to 200 kHz in synchronous rectification and BLDC gate driver applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	40 V - supports 12 V nominal automotive bus with 3× transient margin for load dump events
R_DS(on) max	4.2 mΩ at V_GS = 10 V - enables <1.5 W conduction loss at 60 A, critical for thermally constrained modules
I_D continuous	70 A at T_C = 25 °C - rated for high-current motor phase switches and starter solenoid drivers
E_AS	32 mJ - verified single-pulse avalanche energy allows safe operation under inductive turn-off stress
R_thJC	3.0 K/W - enables efficient heat transfer to heatsink or copper pour, supporting >50 W power dissipation
V_GS(th)	1.2–2.0 V - ensures reliable turn-on with 3.3 V or 5 V logic controllers without gate boosting
Q_g	22–30 nC - determines gate driver power requirement and switching speed trade-off in high-frequency designs

Pinout & Package

IPC70N04S5L4R2ATMA1 is housed in PG-TDSON-8-33 - a thermally enhanced 8-pin surface-mount package with exposed drain pad (pins 1–3 and 7–8 internally connected to drain) and standard SO-8 footprint compatibility.

IC Role / Device Role / Timing Role: High-current latching switch activated by 5 V MCU signal, sustaining 70 A cranking current for 500 ms.

Use Value: Avalanche rating protects against back-EMF when solenoid coil de-energizes; 175 °C rating ensures reliability under hood ambient extremes.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL120N4LF6AG	R_DS(on) = 3.8 mΩ @ 10 V; higher Q_g = 39 nC; same PG-TDSON-8 package	Better conduction loss but slower switching; less suitable for >150 kHz operation	Prefer when thermal budget dominates over switching frequency constraints
IRL8743PBF	R_DS(on) = 4.5 mΩ @ 10 V; no AEC-Q101 qualification; TO-220AB package	Lacks automotive qualification; larger footprint and higher R_thJA; not for under-hood use	Select only for non-automotive industrial prototypes requiring drop-in availability

Compared with STL120N4LF6AG and IRL8743PBF, IPC70N04S5L4R2ATMA1 delivers optimal balance of automotive qualification, logic-level drive, and thermal performance in compact surface-mount form - making it preferred for production-grade 12 V power stages where reliability and space efficiency are jointly critical.

FAQ

What is the maximum allowable gate-source voltage for IPC70N04S5L4R2ATMA1?

The absolute maximum V_GS is ±16 V per datasheet specifications. Operation beyond this risks irreversible gate oxide damage. Recommended gate drive stays within –5 V to +12 V for robustness, especially in noisy automotive environments where ringing may cause overshoot.

Does IPC70N04S5L4R2ATMA1 include an integrated body diode, and what are its characteristics?

Yes - it features a monolithic parasitic body diode with I_S = 70 A continuous forward current and V_SD = 0.8–1.1 V at 35 A and 25 °C. Reverse recovery time is 30 ns with Q_rr = 18 nC, enabling use in synchronous rectification but not ideal for high-frequency freewheeling without snubbing.

Can IPC70N04S5L4R2ATMA1 be used in parallel configurations?

Yes - its positive temperature coefficient for R_DS(on) (increasing with T_j) enables inherently stable current sharing. Successful parallel operation requires matched layout symmetry, identical gate drive impedance, and shared source inductance minimization to avoid dynamic imbalance during switching transitions.

Is IPC70N04S5L4R2ATMA1 suitable for 48 V mild-hybrid applications?

No - its 40 V V_DS rating provides insufficient margin for 48 V nominal bus systems, which experience transients exceeding 60 V during load dump. For 48 V applications, Infineon's OptiMOS™-6 60 V or 75 V devices (e.g., IPB180N04S4) are specified and validated.
