Product details

Overview

AUIRL1404ZL from Infineon is an automotive-grade N-channel enhancement-mode HEXFET® Power MOSFET in TO-262 package, rated for 40 V V_DS, 2.5 mΩ typical R_DS(on) at V_GS = 10 V, and 160 A package-limited continuous drain current. It operates up to 175°C junction temperature and supports fast switching in high-current DC motor drives and battery disconnect circuits.

For engineers reviewing the AUIRL1404ZL datasheet, AUIRL1404ZL pinout, AUIRL1404ZL application, or AUIRL1404ZL equivalent, key selection criteria include logic-level gate drive compatibility (V_GS(th) = 1.4–2.7 V), ultra-low on-resistance under automotive thermal constraints, repetitive avalanche capability (E_AR up to 190 mJ), and RoHS-compliant lead-free construction.

Technical Context

This MOSFET uses advanced planar silicon processing to achieve low R_DS(on) per die area while maintaining robust avalanche performance. Its gate threshold voltage (1.4–2.7 V) enables direct interface with 3.3 V/5 V microcontrollers without level-shifting.

The device features integrated body diode with 26–39 ns reverse recovery time (t_rr) and 18–27 nC reverse recovery charge (Q_rr), supporting synchronous rectification and freewheeling in high-frequency buck converters and H-bridge inverters.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-current automotive MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N4F7AG	40 V, 1.8 mΩ R_DS(on), DFN8 5×6 mm package, no isolated tab	Requires thermal pad soldering; unsuitable for through-hole or heatsink-mounting legacy designs	Select when board space is constrained and thermal management uses PCB copper, not mechanical heatsinks
IRL1404ZPBF	Same die, TO-220AB package, higher R_θJA (62 °C/W vs. TO-262's 40 °C/W on PCB)	Lower power density handling; limited to <100 A continuous in same thermal environment	Select only if existing TO-220 footprint must be retained and peak current remains below 100 A

Compared with STL220N4F7AG and IRL1404ZPBF, AUIRL1404ZL uniquely balances ultra-low R_DS(on), TO-262 mechanical robustness for bolted heatsinks, and AEC-Q101 qualification-making it optimal for high-reliability, high-current automotive power switching where thermal interface and mechanical mounting are critical.

FAQ

What is the maximum continuous drain current for AUIRL1404ZL at 100°C case temperature?

The maximum continuous drain current at T_C = 100°C is 130 A (silicon-limited), as specified in the Absolute Maximum Ratings table. This reflects thermal derating due to reduced channel conductivity and increased R_DS(on) at elevated temperatures, and must be verified against actual PCB thermal design using R_θJC = 0.75 °C/W.

Does AUIRL1404ZL require a gate resistor for safe operation in 100 kHz PWM applications?

Yes-a gate resistor between 4.7 Ω and 10 Ω is recommended to dampen ringing caused by 7.5 nH source inductance and 40 nH drain inductance, especially when driving inductive loads. Without it, V_GS oscillation can exceed ±16 V absolute maximum rating and cause premature failure.

Can AUIRL1404ZL replace AUIRL1404Z in an existing TO-220 layout?

No-AUIRL1404ZL uses TO-262 packaging with different lead spacing, tab geometry, and mounting hole pattern. Direct replacement requires PCB redesign. The TO-220 variant (AUIRL1404Z) has identical electrical specs but higher thermal resistance (R_θJA = 62 °C/W vs. 40 °C/W for TO-262 on PCB).

Is the body diode in AUIRL1404ZL suitable for synchronous rectification in a 48 V DC-DC converter?

Yes-the body diode has 26–39 ns t_rr and 18–27 nC Q_rr, enabling use in synchronous buck topologies up to ~200 kHz. However, its 1.3 V forward voltage at 75 A increases conduction loss versus discrete Schottky solutions; optimal efficiency requires careful dead-time tuning to minimize cross-conduction.
