Product details

Overview

NP82N055NUG-S18-AY from Renesas Electronics is an N-channel power MOSFET in TO-262 package, rated for 55 V V_DSS, 82 A DC drain current, and 6.0 mΩ max R_DS(on) at V_GS = 10 V, designed for high-current automotive switching applications including motor control and DC-DC conversion.

For engineers reviewing the NP82N055NUG-S18-AY datasheet, NP82N055NUG-S18-AY pinout, NP82N055NUG-S18-AY application, or NP82N055NUG-S18-AY equivalent, key selection criteria include its AEC-Q101 qualification, low on-resistance under high-current conditions, thermal resistance of 1.05 °C/W (ch-to-case), and suitability for 48 V battery systems requiring robust avalanche capability (144 mJ).

Technical Context

This device employs a planar vertical DMOS structure optimized for low conduction loss and fast switching in hard-switched topologies. Its gate threshold voltage range (2.0–4.0 V) ensures reliable turn-on with standard 10 V gate drivers, while its 6400 pF typical input capacitance supports stable gate drive design without excessive Miller effect.

The integrated body diode exhibits 0.9–1.5 V forward voltage at 82 A and 42 ns reverse recovery time, enabling synchronous rectification and freewheeling operation in buck converters and H-bridge motor drives without external diode supplementation.

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	40 V V_DSS, 220 A I_D(DC), TO-220FP package, 1.2 mΩ R_DS(on); lower voltage rating but higher current capacity.	Not suitable for 48 V systems due to 40 V rating; better for 24 V commercial vehicle loads.	Select only when system V_bus ≤ 28 V and peak current exceeds 150 A.
IXFH82N55X3	55 V V_DSS, 82 A I_D(DC), TO-247 package, 5.5 mΩ R_DS(on); higher thermal resistance (0.55 °C/W ch-to-case) but superior SOA.	Requires larger PCB footprint and different mounting hardware; not drop-in compatible with TO-262 footprint.	Prefer when board-level thermal constraints permit TO-247 and enhanced safe operating area is critical.

Compared with STL220N4LF8AG and IXFH82N55X3, NP82N055NUG-S18-AY offers optimal balance of 55 V rating, TO-262 mountability, AEC-Q101 compliance, and 6.0 mΩ on-resistance-making it uniquely suited for space-limited, thermally constrained automotive 48 V subsystems where pin-compatible upgrade paths are unavailable.

FAQ

What is the maximum continuous drain current rating for NP82N055NUG-S18-AY?

The NP82N055NUG-S18-AY has a maximum continuous drain current (I_D(DC)) rating of ±82 A at T_C = 25°C. This rating assumes proper heatsinking to maintain case temperature within limits; derating applies above 25°C per the datasheet's power dissipation curve. At T_C = 100°C, the usable I_D(DC) drops to approximately ±55 A. The NP82N055NUG-S18-AY must be mounted to a heatsink with thermal resistance ≤ 1.05 °C/W to sustain full current capability.

Is NP82N055NUG-S18-AY qualified for automotive applications?

Yes, NP82N055NUG-S18-AY is AEC-Q101 qualified and explicitly designed for automotive use. It meets all stress tests required for under-hood deployment-including high-temperature gate bias (HTGB), high-temperature reverse bias (HTRB), temperature cycling, and unbiased highly accelerated stress testing (uHAST). The NP82N055NUG-S18-AY is rated for operation from −40°C to +175°C channel temperature and is approved for use in EPS, transmission control, and 48 V mild hybrid systems.

What is the gate threshold voltage range for NP82N055NUG-S18-AY?

The gate threshold voltage (V_GS(th)) for NP82N055NUG-S18-AY is specified from 2.0 V to 4.0 V at I_D = 250 μA and V_DS = V_GS. This non-logic-level range means the NP82N055NUG-S18-AY requires a minimum 10 V gate drive for full enhancement and low R_DS(on). The NP82N055NUG-S18-AY is not compatible with 3.3 V or 5 V logic-level drivers without level-shifting circuitry.

Does NP82N055NUG-S18-AY have an integrated body diode, and what are its characteristics?

Yes, NP82N055NUG-S18-AY includes an integral body diode with forward voltage (V_F(S-D)) of 0.9–1.5 V at I_F = 82 A and V_GS = 0 V. Its reverse recovery time (t_rr) is 42 ns and reverse recovery charge (Q_rr) is 57 nC under specified test conditions (di/dt = 100 A/μs). These parameters make the NP82N055NUG-S18-AY suitable for synchronous rectification and freewheeling in hard-switched converters where fast recovery minimizes switching loss.

What is the thermal resistance from channel to case for NP82N055NUG-S18-AY?

The channel-to-case thermal resistance (R_th(ch-C)) for NP82N055NUG-S18-AY is 1.05 °C/W, measured under JEDEC JESD51-14 conditions. This value reflects the thermal path from silicon junction to the exposed metal fin (Drain tab), and is critical for calculating maximum allowable power dissipation when mounted to a heatsink. The NP82N055NUG-S18-AY achieves this low R_th via optimized die attach and TO-262 package construction, enabling high-power density designs without forced air cooling.
