Renesas NP80N06MLG-S18-AY

Overview

NP80N06MLG-S18-AY from Renesas Electronics is an N-channel power MOSFET in TO-220 package, rated for 60 V V_DSS, ±80 A DC drain current, and 115 W power dissipation at T_C = 25°C. It features logic-level gate drive (V_GS(th) = 1.4–2.5 V), ultra-low R_DS(on) of 6.7–8.6 mΩ @ V_GS = 10 V / I_D = 40 A, and built-in gate protection diode - optimized for high-efficiency DC-DC converters and automotive motor control.

For engineers reviewing the NP80N06MLG-S18-AY datasheet, NP80N06MLG-S18-AY pinout, NP80N06MLG-S18-AY application, or NP80N06MLG-S18-AY equivalent, key selection criteria include its AEC-Q101 qualification, low R_DS(on) at 4.5 V gate drive (8.4–13.3 mΩ), 4600 pF typical input capacitance, and thermal resistance of 1.30°C/W (ch-to-case), critical for thermally constrained industrial switching designs.

Technical Context

This MOSFET employs a planar trench-gate structure enabling stable conduction under high pulsed currents (±180 A) and repetitive avalanche capability (I_AR = 32 A, E_AR = 102 mJ). Its body diode exhibits VF(S-D) = 0.96–1.5 V @ I_F = 80 A and fast trr = 41 ns, supporting synchronous rectification and freewheeling in hard-switched topologies.

The device integrates a gate-source protection diode to suppress ESD-induced gate oxide failure, and its C_iss/C_oss/C_rss values (4600/370/220 pF typ.) enable predictable switching behavior with minimal external gate drive loss - essential for 100 kHz–500 kHz SMPS designs requiring tight duty-cycle control.

Key Specifications

FAQ

What is the maximum continuous drain current rating for NP80N06MLG-S18-AY at 100°C case temperature?

At T_C = 100°C, the maximum continuous drain current for NP80N06MLG-S18-AY is derated to approximately 58 A, based on the linear derating curve from 80 A at 25°C and 1.30°C/W channel-to-case thermal resistance. This value is confirmed in the "Total Power Dissipation vs. Case Temperature" graph (Data Sheet D19798EJ1V0DS, page 4) and ensures safe operation within SOA limits under sustained thermal load.

Does NP80N06MLG-S18-AY have a built-in body diode, and what are its key conduction parameters?

Yes, NP80N06MLG-S18-AY integrates a parasitic body diode with VF(S-D) = 0.96–1.5 V at I_F = 80 A and reverse recovery time trr = 41 ns. These parameters are measured under specified conditions (V_GS = 0 V, di/dt = 100 A/μs) and support reliable freewheeling in inductive loads - critical for motor drives and synchronous rectification where diode conduction loss and switching loss must be minimized.

Is NP80N06MLG-S18-AY compatible with lead-free reflow soldering processes?

Yes, NP80N06MLG-S18-AY features pure Sn (tin) lead plating and is qualified for lead-free infrared reflow soldering per JEDEC J-STD-020. The recommended profile specifies peak package surface temperature ≤260°C for ≤10 seconds, with time above 220°C limited to ≤60 seconds - fully compliant with RoHS and IPC-A-610 Class 3 assembly standards.

What is the gate-to-source voltage range for NP80N06MLG-S18-AY, and why is the negative rating important?

NP80N06MLG-S18-AY has a gate-to-source voltage rating of ±20 V. The −20 V limit prevents gate oxide damage during negative voltage transients caused by Miller-induced coupling in high-dV/dt switching nodes. Maintaining V_GS ≥ −10 V during turn-off is critical in half-bridge configurations to avoid unintended turn-on due to shoot-through risk - a design consideration explicitly addressed in Renesas' application guidance for this part.

How does the built-in gate protection diode in NP80N06MLG-S18-AY affect circuit design?

The integrated gate-source protection diode in NP80N06MLG-S18-AY clamps ESD events up to human-body-model (HBM) Level 2, reducing susceptibility to gate oxide rupture during handling and assembly. However, Renesas explicitly states that external protection remains necessary if transient voltages exceeding ±20 V may occur in-system - meaning designers must still include a small-signal TVS or RC snubber on the gate line in noisy automotive or industrial environments.
