Product details
Overview
NP82N055KHE-E1-AZ from Renesas Electronics is an N-channel power MOSFET designed for high-current DC-DC converter primary-side switching and motor drive H-bridge legs. It delivers 82 A drain current (DC), 55 V drain-source breakdown voltage, and 2.5 mΩ typical RDS(on) at VGS = 10 V, enabling high-efficiency operation in industrial power supplies and brushless DC motor controllers.
For engineers reviewing the NP82N055KHE-E1-AZ datasheet, NP82N055KHE-E1-AZ pinout, NP82N055KHE-E1-AZ application, or NP82N055KHE-E1-AZ equivalent, this device is selected for high-power switching where low conduction loss, robust avalanche capability (EAS = 49 mJ), and 175°C channel temperature rating are critical design requirements.
Technical Context
This MOSFET employs a planar silicon process with optimized cell pitch and trench-assisted charge balancing to achieve ultra-low on-resistance while maintaining fast switching speed (td(on) = 16 ns typ., tf = 10 ns typ.) and low gate charge (QG = 21 nC typ.). Its built-in gate protection diode provides ESD immunity up to ±20 V, but external clamping remains mandatory for transient overvoltage events.
The device operates in enhancement mode with VGS(th) = 2.0–4.0 V and supports gate drive voltages from 4.5 V to 20 V. Its body diode exhibits VF(S-D) = 1.0 V at IF = 32 A and trr = 40 ns, making it suitable for synchronous rectification and freewheeling paths requiring controlled reverse recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 55 V - Maximum blocking voltage before avalanche onset; defines safe operating range in 48 V bus systems. |
| RDS(on) max | 25 mΩ at VGS = 10 V, ID = 16 A - Limits conduction loss to ≤ 6.4 W at 16 A, enabling compact thermal design. |
| ID(DC) | ±82 A - Sustained current handling capacity at TC = 25°C; enables single-device use in 1–2 kW power stages. |
| EAS | 49 mJ at IAS = 26 A - Energy-handling capability during single-pulse inductive switching; supports reliable operation without snubbers. |
| QG | 21–32 nC - Total gate charge determines driver strength requirement; compatible with standard 2 A peak gate drivers. |
| Tch max | 175°C - Maximum channel temperature rating allows operation in high-ambient environments (e.g., enclosed industrial enclosures). |
| Ciss | 1100–1600 pF - Input capacitance affects gate drive loop stability and turn-on speed; requires careful PCB layout to minimize ringing. |
Pinout & Package
NP82N055KHE-E1-AZ is housed in a TO-252 (JEDEC) / MP-3ZK surface-mount package with exposed drain pad for enhanced thermal dissipation. The package features three main terminals plus an integrated fin connected to the drain for low-inductance mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: Gate | Control electrode | Receives voltage-controlled signal to modulate channel conductivity; requires <20 V absolute max and ESD protection. |
| 2: Drain | High-side power terminal | Connected to input bus or transformer primary; carries full load current and must be routed with low inductance. |
| 3: Source | Reference/return path | Serves as common reference for gate drive and current sensing; ties directly to power ground plane. |
| 4: Fin (Drain) | Thermal & electrical extension | Exposed metal pad soldered to PCB copper pour; provides primary thermal path and reduces Rth(ch-A) to ≤ 40°C/W with 1-in² 2-oz copper. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(on) | 25 mΩ max at 10 V drive enables ≥97% efficiency in 48 V/50 A DC-DC converters at full load. |
| 175°C channel rating | Permits continuous operation in sealed enclosures up to 105°C ambient without derating, reducing need for forced air cooling. |
| Built-in gate protection diode | Clamps ESD transients to ±20 V, simplifying board-level protection design-though external TVS remains required for system-level surges. |
| Low QGD/QG ratio | QGD = 8 nC of total QG = 21–32 nC minimizes Miller plateau duration, improving hard-switching robustness. |
| Fast reverse recovery diode | trr = 40 ns and Qrr = 57 nC reduce switching losses in synchronous rectifier configurations versus standard FRDs. |

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 |
|---|---|---|---|
| IXFH82N55P | RDS(on) = 28 mΩ max; higher QG = 42 nC; TO-247 package | Requires larger PCB footprint and higher gate drive power; better suited for through-hole prototyping or lower-frequency (<100 kHz) designs. | Select when mechanical robustness and serviceability outweigh surface-mount density and switching speed requirements. |
| STB82NF55-18 | RDS(on) = 22 mΩ max; no integrated gate protection diode; TO-263 package | Demands external gate ESD protection; slightly lower conduction loss but increased design complexity for transient immunity. | Choose when gate drive circuit already includes TVS clamping and layout space permits additional protection components. |
Compared with IXFH82N55P and STB82NF55-18, NP82N055KHE-E1-AZ offers the lowest thermal resistance via its MP-3ZK package, fastest switching due to minimal QGD, and built-in gate protection-making it optimal for space-constrained, high-frequency industrial power modules where layout simplicity and thermal performance are prioritized.

FAQ
What is the maximum continuous drain current rating for NP82N055KHE-E1-AZ?
The NP82N055KHE-E1-AZ is rated for ±82 A DC drain current at case temperature TC = 25°C. This rating assumes adequate PCB copper area (≥1 in² 2-oz copper) under the drain fin. At elevated case temperatures, current must be derated per Figure 2 in the datasheet-e.g., to ~55 A at TC = 100°C. The NP82N055KHE-E1-AZ must not be operated beyond its Safe Operating Area (SOA) limits shown in Figure 3.
Does NP82N055KHE-E1-AZ include integrated gate protection?
Yes, the NP82N055KHE-E1-AZ integrates a gate-to-source protection diode rated for ±20 V, providing basic ESD immunity per human-body model. However, Renesas explicitly states that external protection circuitry is mandatory when voltage transients exceeding the rated gate-source voltage may occur. The NP82N055KHE-E1-AZ is not intended to withstand sustained overvoltage or lightning-induced surges without supplemental TVS or RC clamping networks.
What is the typical gate charge profile of NP82N055KHE-E1-AZ?
The NP82N055KHE-E1-AZ has a total gate charge (QG) of 21–32 nC at VDD = 44 V and ID = 32 A, with QGS = 6 nC and QGD = 8 nC. This low QGD/QG ratio results in a short Miller plateau, enabling fast, controllable turn-on and reduced risk of shoot-through in bridge configurations. The NP82N055KHE-E1-AZ gate drive should be sized for ≥2 A peak current to achieve specified td(on) and tf.
Can NP82N055KHE-E1-AZ be used in avalanche mode repeatedly?
No-NP82N055KHE-E1-AZ is characterized for single-pulse avalanche energy (EAS) only: 49 mJ at IAS = 26 A, with strict test conditions (Tch = 25°C, RG = 25 Ω, VGS = 20 → 0 V). Renesas does not specify repetitive avalanche ratings. Repeated avalanche stress degrades RDS(on) and threshold voltage over time. The NP82N055KHE-E1-AZ must be applied within its SOA or protected with active clamping to avoid reliance on avalanche capability.
What is the thermal resistance from channel to ambient for NP82N055KHE-E1-AZ?
The channel-to-ambient thermal resistance (Rth(ch-A)) for NP82N055KHE-E1-AZ is 125°C/W when mounted on a standard FR-4 PCB with minimal copper. With proper layout-including a 1-in² 2-oz copper pour connected to the drain fin-Rth(ch-A) improves to ≤40°C/W. The channel-to-case value is fixed at 2.27°C/W, measured directly from die to the exposed drain pad. These values define the NP82N055KHE-E1-AZ thermal design envelope for industrial applications.
