Product details

Overview

BUK9615-100A,118 from Nexperia is a logic-level N-channel TrenchMOS FET in SOT404 (D2PAK) package, designed for automotive-critical power switching with AEC-Q101 qualification. It delivers 100 V drain-source voltage rating, 75 A continuous drain current at T_mb = 25 °C, and 11.5 mΩ typical R_DS(on) at V_GS = 10 V and T_j = 25 °C, enabling high-efficiency 12 V/24 V battery-fed motor control and load management.

For engineers reviewing the BUK9615-100A,118 datasheet, BUK9615-100A,118 pinout, BUK9615-100A,118 application, or BUK9615-100A,118 equivalent, key selection criteria include its low 5 V gate-drive compatibility, 120 mJ unclamped avalanche energy, junction-to-mounting-base thermal resistance of 0.65 K/W, and automotive-grade reliability under -55 °C to +175 °C operation.

Technical Context

This device uses TrenchMOS technology to achieve low on-resistance while maintaining robust avalanche ruggedness and stable threshold voltage across temperature. Its gate-source threshold voltage ranges from 0.5 V (T_j = 175 °C) to 2.3 V (T_j = -55 °C), ensuring reliable turn-on with 5 V logic drivers even under extreme thermal conditions.

The integrated source-drain diode exhibits 0.85 V forward voltage at 25 A and 25 °C, with 60 ns reverse recovery time and 0.24 µC recovered charge-critical for synchronous rectification and inductive load switching where body diode conduction occurs. Dynamic parameters include 6500 pF typical input capacitance and 325 pF reverse transfer capacitance at V_DS = 25 V.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	100 V - Maximum blocking voltage for 24 V automotive systems with 4× safety margin against load-dump transients.
I_D (continuous)	75 A at T_mb = 25 °C - Supports high-current loads like HVAC blowers and seat motors without external heatsink at ambient mounting base temp.
R_DS(on)	11.5 mΩ typ @ V_GS = 10 V, I_D = 25 A, T_j = 25 °C - Enables <1.8 W conduction loss at 40 A, reducing thermal stress in compact modules.
E_AS	120 mJ unclamped - Withstands single-pulse inductive energy from solenoid or relay coil de-energization without failure.
R_th(j-mb)	0.65 K/W - Allows direct thermal coupling to PCB copper pour or heatsink, achieving ~115 °C max junction temp at 50 W dissipation.
V_GS(th)	1.5 V typ @ I_D = 1 mA - Ensures full enhancement with standard 3.3 V or 5 V microcontroller GPIOs, eliminating need for level shifters.
C_iss	6500 pF typ @ V_DS = 25 V - Defines gate drive strength requirement: ≥2 A peak current needed for 50 ns turn-on with 10 Ω external resistor.

Pinout & Package

Package: SOT404 (D2PAK), plastic surface-mounted package with isolated mounting base electrically connected to drain terminal. Dimensions: 15.8 × 10.3 × 4.5 mm (L × W × H); mounting base area supports >200 W/cm² thermal flux when soldered to 2 oz copper.

Pin/Terminal	Circuit Role	Design Meaning
1 (G)	Gate	Control electrode requiring ≤100 nA leakage at ±10 V; 6500 pF input capacitance dictates gate driver slew rate and power loss.
2 (D)	Drain	Main high-side power terminal; electrically tied to mounting base-must be isolated from heatsink unless referenced to system ground.
3 (S)	Source	Power return path and reference for gate drive; internal 7.5 nH source inductance affects switching oscillation in high-di/dt applications.
Mounting Base (mb)	Drain Connection	Integral thermal and electrical extension of drain; provides primary heat path to PCB/heatsink and must be soldered for rated power handling.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive powertrain and chassis applications per stress test requirements including HTOL, TC, UHAST, and ESD-HBM ≥2 kV.
Logic-level gate drive	Guaranteed turn-on with 5 V supply: R_DS(on) ≤15 mΩ at V_GS = 5 V, enabling direct interface with MCU GPIOs without external level-shifting circuitry.
Low R_DS(on) × Q_g figure-of-merit	11.5 mΩ × 100 nC ≈ 1150 mΩ·nC - Balances conduction and switching losses for PWM frequencies up to 20 kHz in motor drives.
Robust avalanche capability	120 mJ non-repetitive energy rating allows safe operation during inductive flyback events without snubber networks in many 24 V systems.
Optimized body diode	60 ns t_rr and 0.24 µC Q_r minimize reverse recovery losses in half-bridge configurations, reducing cross-conduction risk.

Applications

Engine Cooling Fan Control

Electric Power Steering (EPS) Motor Driver

Use Scenario: Low-side switch in three-phase inverter leg driving 24 V EPS assist motor with regenerative braking.

IC Role / Device Role / Timing Role: Phase-leg switching element; conducts bidirectional current during freewheeling and regeneration via body diode.

Use Value: 60 ns t_rr and low Q_r reduce body-diode switching loss by >40% vs. standard MOSFETs, improving inverter efficiency at 8–15 kHz PWM.

Body Control Module (BCM) Load Management

Automotive LED Headlamp Dimming

Use Scenario: Centralized power distribution for door locks, window lifts, and mirror heaters in 12 V BCM.

IC Role / Device Role / Timing Role: Protected high-current load switch with integrated overtemperature and overcurrent detection support.

Use Value: AEC-Q101 qualification ensures functional safety compliance; 175 °C max T_j enables operation in sealed enclosures near engine bay.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel automotive power switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N10F7	100 V, 220 A, R_DS(on) = 3.2 mΩ @ 10 V; DFN8 5×6 mm package with exposed drain pad.	Higher current rating but requires multi-layer PCB thermal vias; lacks AEC-Q101 certification in standard grade.	Preferred for space-constrained 48 V mild-hybrid systems needing >150 A capability; not drop-in for D2PAK footprint.
IRFB4115PBF	150 V, 115 A, R_DS(on) = 11.5 mΩ @ 10 V; TO-220AB package with insulated tab.	Higher voltage rating suits 42 V legacy systems; slower switching (t_f = 220 ns) increases PWM loss above 5 kHz.	Used where mechanical mounting to heatsink is mandatory and 150 V transient immunity is required; not qualified to AEC-Q101.

Compared with STL220N10F7 and IRFB4115PBF, the BUK9615-100A,118 offers optimal balance of AEC-Q101 compliance, D2PAK thermal performance, and 5 V drive compatibility-making it the preferred choice for cost-sensitive, thermally constrained 12/24 V automotive modules where qualification and footprint are critical.

FAQ

Is BUK9615-100A,118 suitable for high-frequency PWM motor control?

Yes-it supports PWM frequencies up to 20 kHz with minimal switching loss due to its 6500 pF C_iss, 325 pF C_rss, and 130 ns typical rise/fall times. At 10 kHz and 40 A, total switching loss remains below 1.2 W with a 10 Ω gate resistor, making it viable for brushless DC motor inverters in HVAC and EPS systems.

What is the maximum allowable mounting base temperature for continuous 75 A operation?

The datasheet specifies 75 A only at T_mb = 25 °C. Derating begins immediately above that: at T_mb = 100 °C, continuous current drops to 53 A. For sustained 75 A, the mounting base must remain ≤45 °C-achievable with ≥10 cm² 2 oz copper pour and forced airflow or heatsink attachment.

Does the mounting base require electrical isolation from the PCB ground plane?

Yes-the mounting base is internally connected to the drain terminal. If used in high-side configuration or with floating ground references, it must be electrically isolated using insulating thermal pads or ceramic substrates. Direct soldering to a grounded copper pour creates a short circuit unless the drain node is system ground.

How does its body diode performance compare to discrete Schottky alternatives in regenerative braking?

The integrated body diode has 0.85 V V_SD at 25 A and 60 ns t_rr, outperforming most discrete 100 V Schottkys in reverse recovery but with higher forward drop than SiC Schottkys. In 24 V EPS regen, it reduces diode conduction loss by 30% versus standard FRD while avoiding extra component count and layout complexity.
