Product details

Overview

NP40N10PDF-E1-AY from Renesas Electronics is a 100 V, 40 A N-channel power MOSFET in TO-263 (MP-25ZP) package, AEC-Q101 qualified for automotive applications. It delivers R_DS(on) = 27 mΩ max at V_GS = 10 V / I_D = 20 A, features logic-level gate drive, and supports high-current switching in engine control units and DC-DC converters.

For engineers reviewing the NP40N10PDF-E1-AY datasheet, NP40N10PDF-E1-AY pinout, NP40N10PDF-E1-AY application, or NP40N10PDF-E1-AY equivalent, this page provides verified electrical parameters, thermal resistance (R_th(ch-A) = 83.3 °C/W), avalanche capability (E_AS = 61 mJ), and real-world automotive use context - all confirmed from Renesas' R07DS0361EJ0201 Rev.2.01 preliminary datasheet.

Technical Context

This MOSFET uses planar silicon technology with integrated body diode and is optimized for unidirectional high-current switching in 12 V/24 V automotive systems. Its gate threshold voltage (V_GS(th) = 1.5–2.5 V) enables direct microcontroller-level drive, and low C_iss (2100 pF typ.) supports fast switching with reduced gate drive loss.

The device exhibits robust avalanche ruggedness (I_AS = 25 A, E_AS = 61 mJ) and thermal stability up to T_ch = 175 °C. Its R_th(ch-C) = 1.25 °C/W and R_th(ch-A) = 83.3 °C/W (on 40 mm × 40 mm × 1.6 mm glass epoxy PCB with 4% copper) define its thermal envelope under continuous and pulsed operation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	100 V - Maximum blocking voltage compatible with 24 V automotive battery systems with load dump margin.
R_DS(on) max	27 mΩ @ V_GS = 10 V, I_D = 20 A - Enables <1.1 W conduction loss at 20 A, reducing heatsink requirements.
I_D(DC)	±40 A @ T_C = 25°C - Supports high-current motor drivers and solenoid controls without derating at case temperature.
E_AS	61 mJ - Withstands single-pulse inductive energy spikes in relay/coil driving and H-bridge freewheeling.
R_th(ch-A)	83.3 °C/W - Measured on standard 40 mm × 40 mm PCB; defines maximum ambient temperature rise per watt dissipated.
Q_G	47–71 nC - Gate charge magnitude determines required driver current and switching speed trade-off in PWM circuits.
V_GS(th)	1.5–2.5 V - Ensures reliable turn-on with 3.3 V or 5 V logic controllers without level-shifting circuitry.

Pinout & Package

NP40N10PDF-E1-AY is housed in TO-263 (MP-25ZP) surface-mount package with exposed drain pad for thermal and electrical performance. Pin 1 = Gate, Pin 2 = Drain, Pin 3 = Source, Pin 4 = Fin (Drain). The drain terminals (Pins 2 and 4) are internally connected and thermally coupled to the large metal tab.

Pin/Terminal	Circuit Role	Design Meaning
1	Gate	Control terminal; accepts logic-level input (3.3 V/5 V); requires ESD protection due to oxide sensitivity.
2	Drain	Main high-side switching node; electrically and thermally tied to metal tab; connects to load/high-voltage rail.
3	Source	Power return path; referenced to system ground in low-side configurations; used for current sensing.
4	Fin (Drain)	Secondary drain connection enhancing thermal conduction and current capacity; must be soldered to PCB copper pour.

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock testing.
Logic-level gate drive	V_GS(th) ≤ 2.5 V ensures full enhancement with standard MCU GPIOs, eliminating need for gate driver ICs in many designs.
Low R_DS(on) × Q_G figure of merit	27 mΩ × 71 nC = 1917 mΩ·nC - Balances conduction and switching losses for high-efficiency 100 kHz–500 kHz SMPS.
Integrated body diode	V_F(S-D) = 0.9–1.5 V @ I_F = 40 A - Supports synchronous rectification and freewheeling in half-bridge topologies.
High avalanche energy rating	E_AS = 61 mJ - Allows safe operation during inductive turn-off transients without external snubbers in motor control.

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
STL220N10F7	R_DS(on) = 2.2 mΩ @ 10 V (lower), but rated only for 100 V / 220 A; TO-263-7L package with different pinout (G-D-S-D-D-D-D).	Higher current handling and lower R_DS(on), but lacks AEC-Q101 certification and has higher gate charge (120 nC).	Select when higher efficiency at >50 A is critical and automotive qualification is not required.
IXTP40N10P	TO-220 package; R_DS(on) = 30 mΩ @ 10 V; not AEC-Q101 qualified; R_th(ch-A) = 62 °C/W (higher thermal resistance).	Lower cost and widely available, but unsuitable for automotive due to lack of qualification and inferior thermal performance on PCB.	Select for industrial non-automotive applications where TO-220 mounting and lower qualification rigor are acceptable.

Compared with STL220N10F7 and IXTP40N10P, NP40N10PDF-E1-AY uniquely balances AEC-Q101 compliance, TO-263 thermal performance (R_th(ch-A) = 83.3 °C/W), and logic-level drive - making it the only drop-in option for space-constrained, safety-critical automotive modules requiring validated reliability.

FAQ

What is the maximum continuous drain current rating for NP40N10PDF-E1-AY?

The NP40N10PDF-E1-AY is rated for ±40 A DC drain current at case temperature T_C = 25°C. This rating assumes proper PCB copper area (40 mm × 40 mm × 1.6 mm with 4% copper) and thermal management. At higher case temperatures, current must be derated per the Safe Operating Area (SOA) curve on page 4 of the R07DS0361EJ0201 datasheet.

Is NP40N10PDF-E1-AY suitable for 12 V automotive battery systems?

Yes, NP40N10PDF-E1-AY is explicitly designed for automotive applications and AEC-Q101 qualified. Its 100 V V_DSS rating provides sufficient margin for 12 V system load dump transients (up to ~87 V per ISO 7637-2), and its logic-level gate (V_GS(th) = 1.5–2.5 V) interfaces directly with 3.3 V or 5 V microcontrollers used in modern ECUs.

Does NP40N10PDF-E1-AY have avalanche capability, and what are the limits?

Yes, NP40N10PDF-E1-AY is specified for single-pulse avalanche with I_AS = 25 A and E_AS = 61 mJ (T_ch(start) = 25°C, V_DD = 50 V, R_G = 25 Ω, L = 100 μH). This capability is validated per JEDEC JESD24-1 and supports robust operation during inductive turn-off events in motor and solenoid drivers without external snubbers.

What is the thermal resistance from channel to ambient for NP40N10PDF-E1-AY?

The channel-to-ambient thermal resistance R_th(ch-A) for NP40N10PDF-E1-AY is 83.3 °C/W, measured on a standard 40 mm × 40 mm × 1.6 mm glass epoxy PCB with 4% copper area (35 μm). This value defines the temperature rise above ambient per watt of power dissipated and is critical for thermal design of automotive PCB layouts.

Can NP40N10PDF-E1-AY be used in synchronous rectification topologies?

Yes, NP40N10PDF-E1-AY supports synchronous rectification via its integrated body diode (V_F(S-D) = 0.9–1.5 V @ I_F = 40 A) and fast reverse recovery (t_rr = 67 ns, Q_rr = 162 nC). Its low R_DS(on) and logic-level gate allow it to replace Schottky diodes in secondary-side switching of isolated DC-DC converters, improving efficiency by >3% at 20 A loads.
