Product details

Overview

BUK95180-100A from Nexperia is an AEC-Q101-qualified N-channel logic-level TrenchMOS FET in TO-220AB (SOT78A) package, rated for 100 V drain-source voltage, 11 A continuous drain current at T_mb = 25 °C, and 152 mΩ R_DS(on) at V_GS = 10 V/ID = 5 A/25 °C. It serves as a robust power switch in automotive body control modules and engine management subsystems.

For engineers reviewing the BUK95180-100A datasheet, BUK95180-100A pinout, BUK95180-100A application, or BUK95180-100A equivalent, key selection criteria include its 100 V rating, low 165–180 mΩ R_DS(on) at 5 V gate drive, AEC-Q101 qualification, avalanche energy rating of 1.5 mJ, and thermal resistance of 2.8 K/W junction-to-mounting-base.

Technical Context

This device employs TrenchMOS technology to achieve low on-resistance with logic-level gate drive compatibility (V_GS(th) = 1.0–2.0 V typ). Its internal structure supports unclamped inductive switching with defined avalanche ruggedness (E_DS(AL)S = 1.5 mJ), and features integrated source-drain diode with V_SD = 0.85–1.2 V at 5 A.

The TO-220AB package provides direct thermal coupling via the mounting base (connected to drain), enabling high-power dissipation (P_tot = 54 W at T_mb = 25 °C) and stable operation up to T_j = 175 °C. Dynamic parameters include C_iss = 464–619 pF and t_r = 112–157 ns, supporting medium-speed switching in 12 V/24 V automotive systems.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	100 V - Maximum blocking voltage compatible with 24 V automotive systems with margin for load dump transients.
I_D (continuous)	11 A at T_mb = 25 °C - Sustains typical high-side loads like fuel pumps, radiator fans, or headlight drivers without forced cooling.
R_DS(on)	152–173 mΩ at V_GS = 10 V / I_D = 5 A / 25 °C - Enables <1 W conduction loss at 5 A, reducing thermal stress in compact PCB layouts.
R_DS(on) @ 5 V	165–180 mΩ at V_GS = 5 V / I_D = 5 A / 25 °C - Ensures reliable turn-on with standard 5 V microcontroller GPIO without level-shifting.
E_DS(AL)S	1.5 mJ - Withstands single-pulse inductive energy from solenoids or relay coils without failure under unclamped conditions.
R_th(j-mb)	2.8 K/W - Enables efficient heat transfer to external heatsink, supporting >30 W dissipation with modest thermal interface design.
V_GS(th)	1.0–2.0 V typ at 25 °C - Guarantees full enhancement at low gate voltages, critical for fail-safe operation in low-voltage battery conditions.

Pinout & Package

TO-220AB (SOT78A) plastic single-ended package with heatsink-mounted mounting base; 3 leads; 1 mounting hole; drain-connected tab enables direct thermal path to heatsink.

Pin/Terminal	Circuit Role	Design Meaning
1 (G)	Gate	Control terminal accepting logic-level input (0–15 V); requires ≤100 nA leakage current at ±10 V for stable biasing.
2 (D)	Drain	Main high-side power terminal; electrically connected to mounting base for thermal and electrical integration with heatsink.
3 (S)	Source	Power return path; referenced to system ground in low-side configurations or used as common node in high-side layouts.
Mounting base (mb)	Drain connection	Integral metal tab tied internally to drain; must be electrically isolated from chassis unless circuit design explicitly grounds drain.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive applications including engine control, lighting, and power distribution with extended temperature and reliability testing.
TrenchMOS architecture	Delivers lower R_DS(on) per die area than planar MOSFETs, enabling higher current density and reduced PCB footprint.
Logic-level gate drive	Operates fully enhanced at V_GS ≥ 4.5 V, eliminating need for external gate drivers in 5 V MCU-based designs.
Unclamped avalanche rated	Withstands 1.5 mJ single-pulse energy without degradation, simplifying protection design for inductive loads.
Integrated source-drain diode	Provides inherent freewheeling path with V_SD = 0.85–1.2 V at 5 A, suitable for flyback and regenerative braking paths.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP12NK100Z	1000 V rating, 12 A ID, higher R_DS(on) (0.7 Ω min), Zener-protected gate, TO-220FP package.	Targeted at high-voltage industrial SMPS, not automotive; lacks AEC-Q101 qualification and 5 V logic-level drive.	Select only for non-automotive 1000 V applications requiring overvoltage clamping; not a functional substitute for BUK95180-100A.
IRF3205PBF	55 V rating, 110 A ID, 8 mΩ R_DS(on), TO-220AB, no AEC-Q101 certification.	Designed for low-voltage high-current DC-DC converters and motor drives; insufficient voltage margin for automotive 24 V systems.	Use only in 12 V non-automotive applications where 55 V rating suffices; cannot replace BUK95180-100A in 24 V load-dump environments.

Compared with STP12NK100Z and IRF3205PBF, the BUK95180-100A uniquely combines 100 V rating, AEC-Q101 qualification, 5 V logic-level drive, and 1.5 mJ avalanche ruggedness-making it the only viable option for automotive-grade 24 V high-side switching where reliability, thermal efficiency, and gate-drive simplicity are jointly required.

FAQ

What is the maximum junction temperature rating for the BUK95180-100A?

The BUK95180-100A has a maximum junction temperature (T_j) of 175 °C, validated per AEC-Q101 stress testing requirements. This allows sustained operation in under-hood environments where ambient temperatures exceed 125 °C, provided thermal design maintains T_j ≤ 175 °C using the specified R_th(j-mb) = 2.8 K/W path to heatsink. The BUK95180-100A datasheet confirms this limit applies across all operating conditions.

Is the BUK95180-100A pin-compatible with other TO-220AB MOSFETs?

The BUK95180-100A uses standard TO-220AB (SOT78A) pinout: Pin 1 = Gate, Pin 2 = Drain (mounting base), Pin 3 = Source. While mechanical footprint matches generic TO-220AB devices, electrical compatibility depends on voltage/current ratings and gate threshold. The BUK95180-100A is not guaranteed pin-compatible with non-Nexperia parts due to differences in R_DS(on), avalanche capability, and qualification status-even if封装 dimensions align.

Does the BUK95180-100A require a gate resistor for driving with a microcontroller?

A gate resistor is recommended for the BUK95180-100A to control switching speed and suppress ringing, especially in high-di/dt applications. Typical values range from 10 Ω to 47 Ω depending on layout and load inductance. The BUK95180-100A datasheet specifies t_r = 112–157 ns and t_f = 25–38 ns with R_G(ext) = 10 Ω, confirming that direct MCU GPIO connection without series resistance may cause overshoot or EMI issues.

What is the gate-source voltage range specified for the BUK95180-100A?

The BUK95180-100A supports a gate-source voltage (V_GS) range of −15 V to +15 V, per Absolute Maximum Ratings. Operation within −10 V to +10 V is typical for robust switching, with V_GS(th) = 1.0–2.0 V ensuring full enhancement at logic-level drive. Exceeding ±15 V risks permanent gate oxide damage. All BUK95180-100A characterization data assumes V_GS ≤ ±10 V for reliability.

How does the BUK95180-100A perform at elevated temperatures?

The BUK95180-100A exhibits controlled R_DS(on) increase with temperature: 450 mΩ max at V_GS = 5 V / I_D = 5 A / T_j = 175 °C. Its V_GS(th) decreases to 0.5 V min at 175 °C, maintaining turn-on margin. Thermal resistance remains stable at R_th(j-mb) = 2.8 K/W, enabling predictable derating-e.g., I_D drops to 7.7 A at T_mb = 100 °C. These parameters are fully characterized and published in the BUK95180-100A datasheet.
