Product details

Overview

AUIRF1405ZS-7TRL from Infineon Technologies is an automotive-grade N-channel enhancement-mode HEXFET® Power MOSFET in D2PAK-7L package, rated for 55V V_DS, 4.9 mΩ R_DS(on) at V_GS = 10 V, and 120 A continuous drain current at T_C = 25°C. It features 175°C maximum junction temperature, fast switching (t_r = 140 ns, t_f = 130 ns), and rated repetitive avalanche energy up to 250 mJ - optimized for high-efficiency DC-DC converters and motor control in engine management systems.

For engineers reviewing the AUIRF1405ZS-7TRL datasheet, AUIRF1405ZS-7TRL pinout, AUIRF1405ZS-7TRL application, or AUIRF1405ZS-7TRL equivalent, key selection criteria include its low R_DS(on) at high current, robust avalanche capability under unclamped inductive switching, thermal performance with R_θJC = 0.65°C/W, and automotive qualification per AEC-Q101.

Technical Context

This MOSFET employs advanced silicon processing to minimize on-resistance per die area while maintaining ruggedness. Its gate charge profile (Q_g = 150–230 nC, Q_gd = 64 nC) supports high-frequency PWM operation in synchronous buck stages, and the body diode exhibits t_rr = 63–95 ns and Q_rr = 160–240 nC - critical for minimizing commutation losses in bidirectional power conversion.

The device's safe operating area (SOA) is defined by R_DS(on)-limited conduction at DC and pulse-width-limited avalanche at high V_DS/I_D. Thermal design relies on direct case-to-heatsink mounting, as R_θJA = 40°C/W assumes a 1"² FR-4 PCB - underscoring its intended use in thermally constrained automotive modules where junction-to-case path dominates thermal management.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	55 V - Maximum blocking voltage in high-side switch configurations for 48V automotive systems.
R_DS(on)	4.9 mΩ max @ V_GS = 10 V, T_J = 25°C - Enables <1.5 W conduction loss at 88 A, reducing heatsink requirements.
I_D (cont)	120 A @ T_C = 25°C - Supports high-current motor phase legs and starter solenoid drivers without parallel devices.
E_AS	590 mJ - Single-pulse avalanche energy rating ensures reliability during load dump or inductive turn-off transients.
Q_g	230 nC max - Determines gate driver power requirement; ~2.3 W average drive power at 100 kHz, 10 V swing.
T_J max	175°C - Allows operation in under-hood environments with minimal derating versus industrial-grade MOSFETs.
C_oss	1310 pF - Low output capacitance minimizes switching loss during hard-commutation in ZVS-incompatible topologies.

Pinout & Package

Package: D2PAK-7L (TO-263-7), surface-mount with exposed drain pad for thermal and electrical connection. Pin 1–7 follow standard D2PAK-7L layout: pins 1–3 = source, pin 4 = gate, pins 5–7 = drain (common to exposed pad).

Pin/Terminal	Circuit Role	Design Meaning
Pin 1, 2, 3	Source (S)	Low-side return path; internally paralleled for reduced source inductance (L_S = 7.5 nH).
Pin 4	Gate (G)	Control terminal; requires 10 V for full enhancement; threshold V_GS(th) = 2.0–4.0 V.
Pin 5, 6, 7 + Exposed Pad	Drain (D)	Main power output node; electrically and thermally tied to large copper area for R_θJC = 0.65°C/W.

Key Features

Feature	Design Value
Ultra-low R_DS(on)	4.9 mΩ enables >97% efficiency in 48V/100A DC-DC converters at 100 kHz.
175°C junction rating	Permits operation in engine bay locations without forced air cooling or oversized heatsinks.
Repetitive avalanche capability	Rated for repeated unclamped inductive switching up to I_AS = 88 A, supporting robust motor phase protection.
Fast body diode recovery	t_rr = 63 ns and Q_rr = 160 nC reduce cross-conduction loss in synchronous rectification.
AEC-Q101 qualified	Validated for automotive applications including powertrain control units and ADAS actuators.

Use Value: Low Q_gd/Q_g ratio improves noise immunity and reduces gate drive complexity in noisy steering module environments.

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
STL220N4LF8AG	R_DS(on) = 2.2 mΩ @ 10 V, but V_DS = 40 V; smaller DFN8 package; no exposed drain pad.	Limited to 40V systems; unsuitable for 48V load dump; lower thermal mass limits avalanche robustness.	Select only for space-constrained 40V applications where R_DS(on) priority outweighs voltage margin and thermal needs.
IRFP4868PBF	V_DS = 60 V, R_DS(on) = 5.2 mΩ, TO-247 package; not AEC-Q101 qualified; R_θJC = 0.55°C/W.	Higher voltage margin but lacks automotive qualification; through-hole mounting increases assembly cost and inductance.	Prefer for industrial UPS or solar inverters requiring higher V_DS margin and no automotive compliance.

Compared with STL220N4LF8AG and IRFP4868PBF, AUIRF1405ZS-7TRL uniquely balances 55V rating, 4.9 mΩ on-resistance, AEC-Q101 qualification, and D2PAK-7L thermal performance - making it the only choice for thermally demanding, safety-critical 48V automotive power stages.

FAQ

Is AUIRF1405ZS-7TRL pin-compatible with standard D2PAK-3L footprints?

No. AUIRF1405ZS-7TRL uses the D2PAK-7L package with three source pins, one gate pin, and three drain pins plus an exposed drain pad. It requires a dedicated 7-pin footprint and cannot be substituted into a standard 3-pin D2PAK layout without PCB redesign and thermal validation.

What is the maximum recommended gate resistor for driving AUIRF1405ZS-7TRL at 100 kHz?

Based on Q_g = 230 nC and typical gate driver rise/fall times, a 5 Ω to 10 Ω series gate resistor is recommended to limit peak gate current to <2 A while maintaining t_r/t_f < 200 ns. Lower values risk ringing; higher values increase switching losses beyond 100 kHz.

Does AUIRF1405ZS-7TRL require a negative gate turn-off voltage in automotive H-bridge applications?

No. The device's V_GS(th) range (2.0–4.0 V) and robust dV/dt immunity (specified per AEC-Q101) allow reliable turn-off with 0 V gate drive. Negative bias is unnecessary unless operating in extreme noise environments exceeding 50 V/ns dv/dt at the drain.

Can the body diode of AUIRF1405ZS-7TRL be used for freewheeling in continuous conduction mode?

Yes. With V_SD = 1.3 V max and t_rr = 63 ns, the integrated body diode supports freewheeling in CCM for motor drives and DC-DC converters. However, synchronous rectification using complementary FETs is preferred above 10 A to minimize conduction loss.
