Product details

Overview

ISK018NE1LM7AULA1 from Infineon Technologies is an N-channel logic-level Power MOSFET in PG-VSON-6 package, rated for 15 V V_DS, 1.8 mΩ max R_DS(on) at 7 V V_GS, and 129 A continuous drain current at T_C = 25 °C. It features 100% avalanche testing, optimized thermal resistance (R_thJC = 1.6 °C/W typ), and is qualified for industrial applications in high-efficiency SMPS.

For engineers reviewing the ISK018NE1LM7AULA1 datasheet, ISK018NE1LM7AULA1 pinout, ISK018NE1LM7AULA1 application, or ISK018NE1LM7AULA1 equivalent, key selection criteria include low R_DS(on) at 4.5 V gate drive, Q_oss = 6.7 nC for fast switching, and PG-VSON-6 thermal performance in space-constrained synchronous rectification designs.

Technical Context

This OptiMOSTM 7 device uses trench-gate superjunction technology to achieve ultra-low on-resistance with logic-level gate compatibility (V_GS(th) = 1.2–2.0 V). Its 6-pin PG-VSON-6 package integrates a thermally enhanced exposed drain tab for direct PCB copper cooling.

The MOSFET supports high-current pulsed operation (I_D,pulse = 516 A) and exhibits tightly controlled dynamic parameters: C_iss = 1200–1600 pF, C_oss = 620–810 pF, and Q_g = 7.5–9.0 nC (0–4.5 V), enabling efficient operation in 500 kHz+ synchronous buck converters.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	15 V - Maximum blocking voltage for low-voltage synchronous rectification in 12 V input rails.
R_DS(on), max	1.8 mΩ at V_GS = 7 V, I_D = 20 A - Enables <1.5 W conduction loss at 129 A continuous current with proper heatsinking.
I_D, cont	129 A at T_C = 25 °C - Supports high-current output stages in server VRMs and telecom DC/DC modules.
Q_oss	6.7 nC - Low output charge minimizes turn-off energy loss and improves light-load efficiency in hard-switched topologies.
R_thJC	1.6 °C/W typ - Enables >30 W power dissipation with ≤50 °C junction-to-case temperature rise under forced-air cooling.
E_AS	53 mJ - Confirmed single-pulse avalanche ruggedness supports reliable operation during transient overvoltage events.
V_GS(th)	1.6 V typ - Ensures full enhancement with standard 3.3 V or 5 V logic-level gate drivers without level-shifting.

Pinout & Package

PG-VSON-6 is a leadless, surface-mount package with an exposed drain pad (tab) for thermal and electrical connection. Pin 1, 2, 5, 6, and the tab are internally connected to the drain; Pin 3 is the gate; Pin 4 is the source.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 5, 6, tab	Drain	High-current power path with low-inductance, multi-point connection to PCB copper pour for thermal and electrical performance.
3	Gate	Control terminal requiring <9 nC total gate charge; compatible with standard logic-level drivers (3.3 V/5 V).
4	Source	Reference node for gate drive; must be routed with minimal inductance to avoid ringing during fast switching.

Key Features

Feature	Design Value
N-channel logic-level operation	V_GS(th) = 1.2–2.0 V enables direct drive from microcontrollers or PWM controllers without gate driver ICs.
Ultra-low R_DS(on)	1.8 mΩ max at 7 V reduces conduction losses by >40% vs. prior-gen 2.5 mΩ devices in 12 V input SMPS.
100% avalanche tested	Each unit validated to 53 mJ single-pulse E_AS, ensuring robustness in unregulated or fault-prone power systems.
Optimized for synchronous rectification	Low Q_gd/Q_g ratio and fast tr/tf (<2 ns) minimize reverse recovery losses when replacing Schottky diodes.
Pb-free & halogen-free	RoHS-compliant plating and IEC61249-2-21 compliance support environmental requirements for industrial and telecom equipment.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRLHS6342TRPBF	R_DS(on) = 2.3 mΩ @ 4.5 V, Q_g = 8.5 nC, PG-TSON-6 package, no avalanche rating specified	Lower peak current capability (100 A vs. 129 A); suitable only for ≤100 A designs with margin	Prefer where cost sensitivity outweighs avalanche robustness and thermal headroom needs.
SISD18DN-T1-GE3	R_DS(on) = 1.9 mΩ @ 4.5 V, Q_oss = 9.2 nC, SO-8 package, R_thJA = 62 °C/W (no R_thJC spec)	Larger footprint and higher thermal resistance limits power density; not recommended for >60 A continuous use	Select only if SO-8 board layout is fixed and thermal derating to 60 A is acceptable.

Compared with IRLHS6342TRPBF and SISD18DN-T1-GE3, ISK018NE1LM7AULA1 delivers superior thermal performance (1.6 °C/W R_thJC), higher avalanche ruggedness (53 mJ), and lower Q_oss, making it optimal for high-density, high-reliability industrial and telecom power stages.

FAQ

What is the maximum allowable gate-source voltage for ISK018NE1LM7AULA1?

The absolute maximum continuous gate-source voltage is ±7 V, with transient tolerance up to ±8 V for pulses shorter than 20 ns. Exceeding ±7 V continuously risks gate oxide degradation; design must ensure gate driver clamping or limiting to stay within this range during all operating conditions including startup and fault events.

Can ISK018NE1LM7AULA1 be used in parallel configurations?

Yes-its positive temperature coefficient of R_DS(on) (confirmed in Diagram 9) ensures inherent current sharing stability. Layout must balance gate loop inductance and drain-source routing; use individual gate resistors (≥1 Ω) and Kelvin source connections to prevent oscillation and ensure uniform switching behavior across paralleled units.

Is the PG-VSON-6 package compatible with standard reflow profiles?

Yes-the package is qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1 and supports standard lead-free reflow profiles (peak 260 °C, 20–40 s above 217 °C). The exposed drain pad requires ≥80% solder coverage and stencil aperture design matching Infineon's recommended land pattern (Document No. PG-VSON-6-1) for optimal thermal transfer.

Does ISK018NE1LM7AULA1 include an integrated body diode for freewheeling?

Yes-it features a monolithic parasitic body diode with V_SD = 0.79–1.0 V at 20 A and t_rr = 14–32 ns depending on di/dt. While usable for freewheeling, its Q_rr (8–30 nC) and softness are inferior to dedicated SiC Schottky diodes; best practice is to operate in synchronous rectification mode to bypass body diode conduction entirely.
