Product details

Overview

IPI70N04S307AKSA1 from Infineon Technologies is an AEC-Q101 qualified N-channel enhancement-mode power MOSFET in PG-TO262-3-1 package, rated for 40 V V_DS, 80 A continuous drain current at T_C = 25 °C, and 5.2 mΩ typical R_DS(on) at V_GS = 10 V and I_D = 70 A. It operates up to 175 °C junction temperature and is 100% avalanche tested - deployed in automotive DC-DC converters and motor control stages requiring high-current switching with robust thermal performance.

For engineers reviewing the IPI70N04S307AKSA1 datasheet, IPI70N04S307AKSA1 pinout, IPI70N04S307AKSA1 application, or IPI70N04S307AKSA1 equivalent, key selection criteria include its 1.9 K/W R_thJC, 6.2 mΩ max R_DS(on) (SMD version), 2050 pF C_iss, 145 mJ E_AS, and AEC-Q101 qualification for under-hood automotive use.

Technical Context

This OptiMOS®-T device uses trench-based silicon technology optimized for low conduction and switching losses in high-duty-cycle, high-current applications. Its gate threshold voltage (2.1–4.0 V) enables reliable turn-on with standard 5 V or 10 V logic-level drivers, while its 12 nC typical Q_gs and 30 nC total Q_g support fast, efficient switching at frequencies up to several hundred kHz.

The integrated body diode exhibits 1.0–1.3 V forward voltage at 70 A and 25 °C, with 34 ns t_rr and 36 nC Q_rr, enabling synchronous rectification and freewheeling operation without external diodes in many buck or half-bridge topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	40 V - Maximum blocking voltage before breakdown; sets upper limit for input rail in 12 V/24 V automotive systems.
R_DS(on) max	6.2 mΩ - Measured at V_GS = 10 V, I_D = 70 A, SMD version; determines conduction loss and heatsink sizing.
I_D continuous	80 A at T_C = 25 °C - Limited by bondwire; derates to 58 A at T_C = 100 °C for sustained load handling.
E_AS	145 mJ - Single-pulse avalanche energy at I_D = 50 A; enables robustness against inductive switching transients.
R_thJC	1.9 K/W - Junction-to-case thermal resistance; defines minimum heatsink requirement for thermal management.
Q_g total	30–40 nC - Gate charge required for full turn-on; directly impacts driver power and switching speed trade-offs.
t_r/t_f	8 ns / 7 ns - Rise/fall times at V_DD = 20 V, R_G = 3.5 Ω; supports high-frequency PWM with low switching loss.

Pinout & Package

Package: PG-TO262-3-1 - Insulated plastic case with isolated tab, 3-pin through-hole variant of TO-262, compatible with TO-220 footprint but with improved creepage/clearance and thermal performance. Tab is electrically connected to drain.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Source terminal	Low-side reference node; connects to ground or low-side switch node; carries full load current in low-side configuration.
Pin 2 (Gate)	Control input	High-impedance MOSFET gate; requires <100 nA leakage drive; sensitive to ESD and ringing without proper gate resistor.
Pin 3 (Drain / Tab)	Power output / heat sink interface	High-current drain path; electrically tied to metal tab; must be thermally coupled to heatsink and electrically isolated if floating topology used.

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive under-hood environments including temperature cycling, humidity, and mechanical shock per AEC standard.
100% avalanche tested	Each unit subjected to single-pulse avalanche stress at I_D = 50 A, ensuring ruggedness in inductive load switching.
175 °C maximum operating temperature	Enables placement near hot components (e.g., engine bay ECUs) without thermal derating penalties beyond datasheet curves.
Green RoHS-compliant packaging	Halogen-free, lead-free construction meeting EU Directive 2011/65/EU and JEDEC J-STD-020 MSL1 reflow profile (260 °C peak).
Optimized body diode	34 ns reverse recovery time and 36 nC Q_rr reduce commutation loss and EMI in synchronous rectifier and freewheeling applications.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPB70N04S307AKSA1	PG-TO263-3-2 package; 1.9 K/W R_thJC; same die, different leadframe and mounting.	SMD assembly; requires PCB copper area for thermal dissipation.	Select when surface-mount manufacturing and automated reflow are required.
IPP70N04S307AKSA1	PG-TO220-3-1 package; identical electrical specs but higher R_thJC (2.2 K/W) due to smaller case size.	Through-hole mounting; lower thermal performance limits peak current in compact heatsinks.	Select when legacy through-hole assembly or mechanical retention is preferred over thermal optimization.

Compared with IPB70N04S307AKSA1 and IPP70N04S307AKSA1, IPI70N04S307AKSA1 offers identical silicon performance in a PG-TO262-3-1 package - balancing thermal efficiency (1.9 K/W), mechanical robustness, and compatibility with TO-220 footprints while supporting automated insertion.

FAQ

What is the maximum allowable gate-source voltage for IPI70N04S307AKSA1?

The absolute maximum V_GS is ±20 V. Operation above +20 V risks permanent gate oxide damage; recommended drive is 10 V for full enhancement with margin. Gate drive circuits must include clamping or Zener protection to prevent overshoot during fast switching transitions.

Does IPI70N04S307AKSA1 require a heatsink in all applications?

Yes - even at moderate currents, junction temperature rise exceeds safe limits without thermal management. With R_thJC = 1.9 K/W and P_tot = 79 W at T_C = 25 °C, a heatsink with ≤ 1.5 K/W total R_thJA is required for continuous 80 A operation. Derating applies above 25 °C ambient.

Is the body diode in IPI70N04S307AKSA1 suitable for synchronous rectification?

Yes - its 34 ns t_rr, 36 nC Q_rr, and 1.0–1.3 V V_SD at 70 A make it viable for synchronous rectification in buck converters up to ~300 kHz. However, external Schottky diodes may still be preferred in ultra-low-loss or high-frequency (>500 kHz) designs.

How does the AEC-Q101 qualification impact design validation for IPI70N04S307AKSA1?

AEC-Q101 certification confirms qualification for automotive use across temperature, humidity, vibration, and lifetime stress tests - eliminating need for redundant qualification testing. Designers must still verify layout, thermal interface, and gate drive per application-specific conditions, especially under load-dump or cold-crank scenarios.
