Product details

Overview

IPP70N04S406AKSA1 from Infineon Technologies is a 40 V, 70 A N-channel enhancement-mode power MOSFET in PG-TO220-3-1 package, AEC-qualified for automotive applications, with 6.2 mΩ max R_DS(on) at V_GS = 10 V and 100% single-pulse avalanche tested to 72 mJ. It operates up to 175 °C and supports high-current motor drive and DC-DC converter primary-side switching.

For engineers reviewing the IPP70N04S406AKSA1 datasheet, IPP70N04S406AKSA1 pinout, IPP70N04S406AKSA1 application, or IPP70N04S406AKSA1 equivalent, key selection criteria include R_DS(on) at 70 A, thermal resistance (R_thJC = 2.6 K/W), avalanche ruggedness, gate charge profile (Q_g = 24.5–32.0 nC), and AEC-Q101 qualification status.

Technical Context

This OptiMOS™-T2 device uses trench-gate superjunction technology optimized for low conduction and switching losses in 12 V automotive systems. Its 5.6 mΩ typical R_DS(on) at 70 A and 10 V gate drive enables high-efficiency synchronous rectification and H-bridge motor control.

The MOSFET features tightly controlled gate threshold voltage (2.0–4.0 V), low reverse transfer capacitance (C_rss = 15–35 pF), and fast switching (t_r = 10 ns, t_f = 9 ns) under 3.5 Ω gate resistance - critical for minimizing shoot-through risk in half-bridge topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	40 V - Maximum drain-source blocking voltage for 12 V battery rail systems with transient margin
R_DS(on) max	6.2 mΩ at V_GS = 10 V, I_D = 70 A - Enables <1.5 W conduction loss at full load in TO-220 footprint
I_D continuous	70 A at T_C = 25 °C - Supports high-current automotive loads without forced cooling
E_AS	72 mJ - Confirmed single-pulse avalanche energy rating ensures robustness against inductive switching stress
R_thJC	2.6 K/W - Low junction-to-case thermal resistance allows direct heatsink mounting for thermal management
Q_g	24.5–32.0 nC - Gate charge range defines required driver current for <100 ns turn-on/turn-off in PWM control
AEC-Q101	Qualified - Meets automotive reliability standard for temperature cycling, humidity, and mechanical shock

Pinout & Package

IPP70N04S406AKSA1 is housed in PG-TO220-3-1 package: insulated case, vertical lead orientation, 3-terminal through-hole mounting with tab-drain configuration. The metal tab is electrically connected to the drain terminal and serves as primary thermal path.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main current path output / heat sink interface	Electrically tied to MOSFET drain; requires isolation washer when mounted to grounded heatsink
Source	Reference node for gate drive and current sensing	Low-inductance connection point for shunt resistor placement and gate driver return path
Gate	Control input for channel conduction	High-impedance terminal requiring <32 nC total charge for full enhancement; sensitive to ESD

Key Features

Feature	Design Value
N-channel enhancement mode	Self-turn-off behavior eliminates need for pull-down resistors in gate drive circuits
100% avalanche tested	Guarantees minimum 72 mJ single-pulse energy handling without parameter shift or failure
MSL1 reflow rating	Withstands peak solder temperatures up to 260 °C - compatible with standard lead-free PCB assembly
Green Product (RoHS)	Lead-free terminations and halogen-free mold compound meet EU Directive 2011/65/EU requirements
175 °C operating temperature	Enables deployment in engine bay locations where ambient exceeds 125 °C

FAQ

What is the maximum gate-source voltage rating for IPP70N04S406AKSA1?

The absolute maximum gate-source voltage is ±20 V. Operation beyond ±15 V risks permanent gate oxide damage. Recommended gate drive is 10 V for full enhancement, with 5.9 V gate plateau voltage confirmed in gate charge testing - ensuring reliable turn-on even with driver voltage droop.

Does IPP70N04S406AKSA1 require a gate resistor, and what value is recommended?

Yes - a series gate resistor is required to control dV/dt and prevent oscillation. With R_G = 3.5 Ω, typical turn-on delay is 8 ns and rise time is 10 ns. For 500 kHz PWM in DC-DC converters, 2.2–4.7 Ω balances switching speed and EMI; values below 1.5 Ω increase ringing risk without meaningful efficiency gain.

Is IPP70N04S406AKSA1 suitable for linear-mode operation?

It is rated for linear operation per SOA curves on page 4 of the datasheet, supporting continuous operation up to 200 V·A at T_C = 25 °C. However, sustained linear use above 10 W requires active heatsinking due to R_thJC = 2.6 K/W - not recommended for unregulated analog regulators without thermal derating.

How does the 100% avalanche test impact field reliability?

Each unit undergoes single-pulse avalanche stress at I_AS = 70 A and E_AS = 72 mJ, verifying no parametric shift or catastrophic failure. This screening ensures robustness against inductive kickback in motor drives and relay coils - reducing field returns related to transient overstress by >90% versus non-avalanche-tested equivalents.
