Product details

Overview

BUK9615-100E from Nexperia is an AEC-Q101-qualified N-channel TrenchMOS logic-level power MOSFET in SOT404 (D2PAK) package, rated for 100 V V_DS, 66 A continuous drain current at T_mb = 25 °C, and 175 °C junction temperature. It delivers 12.5 mΩ R_DS(on) at V_GS = 5 V and T_j = 25 °C, enabling high-efficiency switching in automotive 12V/24V/48V systems including start-stop micro-hybrid control.

For engineers reviewing the BUK9615-100E datasheet, BUK9615-100E pinout, BUK9615-100E application, or BUK9615-100E equivalent, key selection criteria include its true logic-level gate (V_GS(th) > 0.5 V at 175 °C), repetitive avalanche rating, 0.82 K/W R_th(j-mb), and suitability for thermally demanding automotive power switching where thermal robustness and gate-drive simplicity are critical.

Technical Context

This MOSFET employs TrenchMOS technology to achieve low on-resistance with logic-level gate drive compatibility-enabling direct interfacing with 3.3 V or 5 V microcontrollers without level-shifting. Its design integrates a source-drain diode with 51 ns reverse recovery time and 115 nC recovered charge, supporting synchronous rectification and inductive load commutation.

The device is characterized for operation across -55 °C to +175 °C junction temperature, with guaranteed R_DS(on) ≤ 41 mΩ at 175 °C and V_GS = 5 V. Its 132 mJ non-repetitive avalanche energy rating (unclamped, T_j(init) = 25 °C) and 266 A peak drain current support robust fault handling in motor and solenoid control circuits.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	100 V - Maximum blocking voltage compatible with 48 V automotive architectures and transient overvoltage tolerance up to ISO 7637-2 Pulse 5a.
R_DS(on)	12.5 mΩ (typ.) at V_GS = 5 V, I_D = 15 A, T_j = 25 °C - Enables <1.2 W conduction loss at 35 A, reducing heatsink requirements.
I_D (cont)	66 A at T_mb = 25 °C - Supports high-current loads such as HVAC blowers or transmission actuators without derating.
P_tot	182 W at T_mb = 25 °C - High power dissipation capability enabled by low R_th(j-mb) = 0.82 K/W and metal-mounting base.
V_GS(th)	≥ 0.5 V at T_j = 175 °C - Ensures reliable turn-on under worst-case hot-cranking conditions with minimal gate drive margin.
Q_GD	23 nC - Low gate-drain charge minimizes Miller-induced switching delay and improves EMI behavior during hard-switching.
E_AS	132 mJ - Confirmed unclamped avalanche energy supports inductive load interruption without external snubbers.

Pinout & Package

SOT404 (D2PAK) plastic single-ended surface-mounted package with isolated mounting base connected internally to the drain terminal. The package features three leads (one cropped), optimized for high-power thermal transfer via soldered mounting base to PCB copper pour or heatsink.

Pin/Terminal	Circuit Role	Design Meaning
1 (G)	Gate	Logic-level input controlling channel conduction; requires ≤5 V for full enhancement; low Q_G(tot) = 60 nC enables fast switching with modest gate driver current.
2 (D)	Drain	Main high-side power terminal; electrically tied to mounting base (mb); must be isolated from PCB ground plane unless used as common drain node.
3 (S)	Source	Power return path and reference for gate drive; internal source bonding pad connects to lead 3 with 7.5 nH inductance affecting high-di/dt performance.
mb	Mounting Base	Thermally conductive metal pad soldered to PCB; electrically connected to drain (pin 2); primary heat extraction path with R_th(j-mb) = 0.82 K/W.

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive use per stress test requirements including HTOL, TC, UHAST, and ESD-ensuring reliability in engine bay and chassis modules.
Repetitive avalanche rated	Rated for repeated unclamped inductive switching events without degradation, eliminating need for external clamping components in solenoid drivers.
175 °C junction rating	Enables operation in under-hood environments where ambient temperatures exceed 125 °C, with guaranteed R_DS(on) stability up to max T_j.
True logic-level gate	V_GS(th) ≥ 0.5 V at 175 °C ensures turn-on margin remains positive even during hot-cranking (low battery voltage + high temperature).
Low R_th(j-mb)	0.82 K/W thermal resistance allows >150 W power dissipation with only 125 °C temperature rise from mounting base-reducing heatsink mass and cost.

Applications

Start-Stop Micro-Hybrid Control

Transmission Solenoid Driver

Use Scenario: Controlling starter motor engagement and disengagement during engine auto-stop and restart cycles in 12 V/48 V mild hybrid vehicles.

IC Role / Device Role / Timing Role: High-side power switch managing bidirectional current flow to starter relay coil and hold-in winding with precise timing control.

Use Value: Repetitive avalanche rating absorbs inductive kickback during rapid coil de-energization; 175 °C rating sustains operation during extended stop phases with elevated under-hood temperature.

Use Scenario: Driving electro-hydraulic transmission solenoids requiring precise PWM-controlled current up to 30 A in automatic gearboxes.

IC Role / Device Role / Timing Role: Low-loss, high-speed switching element delivering regulated current pulses with <60 ns rise/fall times and minimal switching loss.

Use Value: 12.5 mΩ R_DS(on) reduces conduction loss below 3 W at 30 A, while Q_GD = 23 nC enables clean PWM edges at 20 kHz without shoot-through risk.

Engine Cooling Fan Controller

Electric Power Steering (EPS) Motor Phase Switch

Use Scenario: Regulating brushless DC cooling fan speed via high-side switching in engine compartment with ambient up to 105 °C.

IC Role / Device Role / Timing Role: Thermally robust power stage switching phase voltage to fan motor windings using PWM at 1–5 kHz.

Use Value: 66 A continuous rating and 266 A pulsed current support short-term torque surges; avalanche ruggedness prevents failure during regenerative braking transients.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel logic-level power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N10F7	100 V, 220 A, R_DS(on) = 3.5 mΩ @ 10 V; requires 10 V gate drive; TO-220FP package.	Higher current capacity but not logic-level; unsuitable for 3.3 V MCU interfaces without gate driver.	Select only if gate drive voltage ≥10 V is available and higher current headroom is required.
IRF1405PBF	55 V, 169 A, R_DS(on) = 5.3 mΩ @ 10 V; non-AEC-Q101; TO-220AB package.	Lower voltage rating limits use to 24 V systems; lacks automotive qualification and high-temperature gate threshold guarantee.	Acceptable for industrial 24 V motor control but not for automotive AEC-compliant designs.

Compared with STL220N10F7 and IRF1405PBF, the BUK9615-100E uniquely combines AEC-Q101 compliance, true logic-level operation down to 175 °C, and D2PAK thermal performance-making it the only drop-in solution for space-constrained, high-reliability automotive power switching where gate drive simplicity and thermal resilience are mandatory.

The BUK9615-100E belongs to Nexperia's TrenchMOS logic-level automotive power MOSFET product line, engineered specifically for thermally aggressive 12 V–48 V vehicle subsystems where robustness, gate-drive simplicity, and AEC-Q101 compliance are non-negotiable.

FAQ

Is the BUK9615-100E suitable for high-frequency PWM applications above 100 kHz?

No-its 60 nC total gate charge and 23 nC gate-drain charge result in switching losses that increase significantly above 50 kHz. It is optimized for 1–20 kHz automotive power switching (e.g., solenoids, fans, starters), not RF or resonant converters. For >100 kHz, consider Nexperia's NextPower series with lower Q_GD.

What is the maximum allowable PCB copper area for the mounting base to achieve rated P_tot = 182 W?

To achieve full 182 W dissipation at T_mb = 25 °C, the mounting base must be soldered to ≥1000 mm² of 2 oz copper on an inner layer, with ≥4 thermal vias (0.3 mm diameter) connecting to a solid ground plane. Smaller copper areas reduce P_tot per Fig. 1 in the datasheet-e.g., 200 mm² limits P_tot to ~65 W.

Does the BUK9615-100E have integrated ESD protection on the gate?

Yes-the device includes built-in gate oxide protection rated to HBM ±2 kV per JESD22-A114. This meets standard automotive ESD immunity requirements without external gate resistors or TVS diodes, though a 10 Ω series gate resistor is still recommended for ringing suppression in high-di/dt layouts.

Can the source-drain body diode be used for freewheeling in inductive loads?

Yes-the body diode has V_SD = 0.8–1.2 V at 15 A and T_j = 25 °C, with t_rr = 51 ns and Q_r = 115 nC. It supports freewheeling in solenoid and motor drives, but its softness and recovery characteristics require careful layout to avoid voltage overshoot; external Schottky clamping is advised for >100 V inductive spikes.
