Product details

Overview

AUIRF540ZSTRL from Infineon is an automotive-grade N-channel enhancement-mode Power MOSFET in D2PAK (TO-263) package, rated for 100 V V_DS, 36 A continuous drain current at T_C = 25°C, and 21 mΩ typical R_DS(on) at V_GS = 10 V. It delivers fast switching (t_r = 51 ns, t_f = 39 ns), 175°C junction operation, and 120 mJ tested single-pulse avalanche energy - deployed in engine control modules, DC-DC converters, and motor drivers.

For engineers reviewing the AUIRF540ZSTRL datasheet, AUIRF540ZSTRL pinout, AUIRF540ZSTRL application, or AUIRF540ZSTRL equivalent, key selection criteria include its automotive qualification per AEC-Q101, low conduction loss at high current, thermal robustness under repetitive avalanche stress, and compatibility with standard gate-drive voltages (±20 V).

Technical Context

This HEXFET® device uses advanced silicon processing to minimize on-resistance per die area while maintaining rugged unclamped inductive switching capability. Its 175°C maximum junction temperature and 1.64°C/W R_θJC support high-power density designs in constrained thermal environments.

The MOSFET features a body diode with 33–50 ns reverse recovery time (t_rr) and 41–62 nC Q_rr, enabling efficient freewheeling in synchronous rectification and H-bridge topologies. Gate charge parameters (Q_g = 42–63 nC, Q_gd = 15 nC) indicate moderate drive strength requirements for 100 kHz–500 kHz switching.

Key Specifications

T_J max	175°C - Meets AEC-Q101 Grade 0 requirements for under-hood power electronics.

Pinout & Package

Package: D2PAK (TO-263), surface-mount, isolated tab (drain-connected), 3-pin configuration with exposed copper pad for thermal transfer.

Pin/Terminal	Circuit Role	Design Meaning
1 (G)	Gate	Control terminal; requires 10 V for full enhancement; ±20 V absolute max rating prevents ESD damage.
2 (D)	Drain	Main power output; electrically connected to exposed tab; must be isolated from heatsink unless referenced to system ground.
3 (S)	Source	Power return path; reference node for gate drive; low-inductance layout critical for dv/dt immunity.

Key Features

Feature	Design Value
Automotive qualification	AEC-Q101 qualified - Validated for temperature cycling, humidity, and mechanical shock in engine bay environments.
Repetitive avalanche rating	Allowed up to T_Jmax - Enables robust operation in unclamped inductive loads (e.g., fuel injectors, fan motors) without external snubbers.
Ultra-low R_DS(on)	21 mΩ typ. - Reduces I²R losses by >30% vs. legacy 100 V MOSFETs, improving efficiency in 48 V mild-hybrid systems.
Fast body diode	t_rr = 33–50 ns, Q_rr = 41–62 nC - Minimizes reverse-recovery loss and EMI in synchronous buck and half-bridge configurations.
Thermal performance	R_θJA = 40°C/W (PCB mount) - Achieves 36 A continuous current with 1"² FR-4 copper area, eliminating need for bolted heatsinks.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel 100 V power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL130N10F7	R_DS(on) = 9.5 mΩ @ 10 V, but only rated for 130 A pulsed; no AEC-Q101 qualification; TO-220FP package.	Lacks automotive qualification and thermal robustness for under-hood use; better suited for industrial SMPS.	Select only for non-automotive cost-sensitive designs where qualification is not required.
IRF540NPBF	Same R_DS(on) (21 mΩ) and V_DS (100 V), but commercial-grade (not AEC-Q101); TO-220 package; lower E_AS (83 mJ).	Not validated for automotive temperature cycling or humidity; unsuitable for safety-critical ECUs.	Acceptable for prototyping or non-automotive 12 V motor drives where qualification is waived.

Compared with STL130N10F7 and IRF540NPBF, AUIRF540ZSTRL uniquely combines AEC-Q101 compliance, 175°C operation, and 120 mJ tested avalanche energy - making it the only choice for production automotive power stages requiring functional safety alignment.

FAQ

Is AUIRF540ZSTRL pin-compatible with IRF540N?

No - AUIRF540ZSTRL uses D2PAK (TO-263) packaging with drain-connected tab, while IRF540N uses TO-220 with isolated tab. Pin numbering differs: D2PAK has G-D-S left-to-right; TO-220 has G-D-S front-view. PCB layout and thermal interface must be redesigned.

What is the maximum recommended gate resistor for 200 kHz switching?

A 10 Ω gate resistor is recommended for 200 kHz operation, balancing switching speed (t_r/t_f ≈ 50 ns) and gate oscillation suppression. Lower values (<5 Ω) increase EMI risk; higher values (>22 Ω) raise switching losses beyond 1.5 W at 30 A.

Does AUIRF540ZSTRL require a negative gate voltage for reliable turn-off?

No - the device fully turns off at V_GS = 0 V due to its 2.0–4.0 V threshold voltage range. Negative gate bias is unnecessary and not recommended, as V_GS rating is only ±20 V and negative voltage adds no benefit to dv/dt immunity or leakage control.

Can AUIRF540ZSTRL replace AUIRF3205 in a 24 V motor driver?

No - AUIRF3205 is a 55 V device (V_DS = 55 V); using AUIRF540ZSTRL (100 V) introduces higher R_DS(on) (21 mΩ vs. 8 mΩ) and larger gate charge, degrading efficiency. Select AUIRF5706 (100 V, 11 mΩ) instead for voltage upgrade with minimal trade-offs.
