Product details
Overview
BUK92150-55A/CDJ from Nexperia is a logic-level N-channel TrenchMOS FET in DPAK (SOT428) package, rated for 55 V VDS, 11 A continuous drain current at Tmb = 25 °C, and 175 °C junction temperature. It delivers RDS(on) = 120 mΩ (typ) at VGS = 5 V and Tj = 25 °C, and is AEC-Q101 qualified for automotive power switching in 12 V/24 V systems.
For engineers reviewing the BUK92150-55A/CDJ datasheet, BUK92150-55A/CDJ pinout, BUK92150-55A/CDJ application, or BUK92150-55A/CDJ equivalent, this device supports thermally demanding automotive load control with logic-compatible gate drive, low conduction loss, and unclamped avalanche ruggedness of 16 mJ.
Technical Context
This MOSFET uses TrenchMOS technology to achieve low RDS(on) while maintaining robust thermal performance up to 175 °C junction temperature. Its gate threshold voltage (VGS(th)) ranges from 0.5 V (min at Tj = 175 °C) to 2.3 V (max at Tj = −55 °C), enabling reliable turn-on with standard 5 V microcontroller outputs.
The device features integrated source-drain diode with VSD = 0.85 V (typ) at IS = 15 A and Tj = 25 °C, and exhibits dynamic parameters including QGD = 2.6 nC and Ciss = 240–338 pF, supporting efficient switching in motor and solenoid drive circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 55 V maximum - supports 24 V automotive systems with ≥2× voltage margin against transients |
| ID (continuous) | 11 A at Tmb = 25 °C - enables direct driving of medium-power loads without heatsink in ambient-limited designs |
| RDS(on) | 120 mΩ typ at VGS = 5 V, Tj = 25 °C - reduces conduction loss to ≤6.6 W at 11 A, easing thermal management |
| Tj max | 175 °C - allows operation in under-hood environments without derating below full current rating |
| Avalanche energy EAS | 16 mJ unclamped - provides single-pulse robustness against inductive kickback in relay/solenoid switching |
| Rth(j-mb) | 4.1 K/W - enables high-power dissipation via PCB copper pad mounting base, critical for surface-mount reliability |
| QG(tot) | 6 nC - ensures fast, low-drive-current switching with standard logic-level gate drivers |
Pinout & Package
Package: DPAK (SOT428), plastic single-ended surface-mounted package with 3 leads (one lead cropped); mounting base (mb) electrically connected to drain.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | Gate | Logic-level control input; accepts 5 V TTL/CMOS drive with VGS(th) ≤ 2 V for guaranteed turn-on |
| 2 (D) | Drain | Main power output terminal; internally bonded to mounting base for low-inductance, high-current path and thermal conduction |
| 3 (S) | Source | Power return node; referenced to system ground; forms common node for gate drive and load current return |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive compatibility | Operates fully enhanced at VGS = 5 V, eliminating need for gate boosters in MCU-driven automotive modules |
| AEC-Q101 qualification | Validated for automotive safety-critical applications including body control modules and engine peripherals |
| 175 °C junction rating | Enables uninterrupted operation in under-bonnet locations where ambient exceeds 105 °C |
| Low RDS(on) × QG figure-of-merit | ~720 mΩ·nC - balances conduction and switching losses for high-efficiency 10–100 kHz PWM loads |
| Integrated source-drain diode | VSD = 0.85 V (typ) at 15 A - supports freewheeling in inductive loads without external diode |
Applications
| Automotive Body Control Module | 12 V DC Motor Driver |
|---|---|

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 |
|---|---|---|---|
| STL130N5LF8AG | 60 V VDS, 130 A ID, RDS(on) = 3.8 mΩ @ 10 V - requires higher gate drive voltage and larger footprint (PowerFLAT 5x6) | Targeted at high-current industrial inverters, not automotive space-constrained modules | Select only if >100 A peak current and lower RDS(on) outweigh gate drive complexity and layout area |
| ON Semiconductor NTMFS5C670NL | 60 V VDS, 100 A ID, RDS(on) = 4.2 mΩ @ 10 V - non-logic-level (VGS(th) = 2–4 V), requires 10 V gate drive for full enhancement | Designed for server PSU OR-ing and telecom hot-swap, lacks AEC-Q101 qualification | Not suitable for automotive use; consider only for non-automotive 24 V systems with dedicated 10 V gate driver |
Compared with STL130N5LF8AG and NTMFS5C670NL, BUK92150-55A/CDJ uniquely combines AEC-Q101 compliance, true 5 V logic-level operation, DPAK footprint, and 175 °C capability-making it the only drop-in solution for space- and temperature-constrained automotive load switching.

FAQ
Is BUK92150-55A/CDJ pin-compatible with BUK92150-55A?
Yes - both share identical DPAK (SOT428) package outline and pin configuration (G-D-S). The /CDJ suffix denotes a specific tape-and-reel packaging variant per Nexperia's ordering matrix, with no electrical or mechanical differences affecting PCB layout or circuit design.
What is the maximum continuous drain current at 100 °C mounting base temperature?
Per Figure 3 in the datasheet, the continuous drain current drops to 7.8 A at Tmb = 100 °C with VGS = 5 V. This derating reflects thermal limits of the DPAK package and must be applied in designs where PCB copper area or airflow cannot maintain Tmb ≤ 25 °C.
Does BUK92150-55A/CDJ include an integrated ESD protection diode?
No - the device does not integrate gate ESD protection. External Zener clamping (e.g., 12 V TVS between G and S) is recommended when exposed to human-handling or connector mating events, especially in automotive assembly lines per ISO 10605.
Can BUK92150-55A/CDJ be used in high-frequency PWM applications above 100 kHz?
Its QGD = 2.6 nC and Ciss = 240–338 pF support switching up to ~200 kHz, but total gate charge (6 nC) and RDS(on) trade-offs make it most efficient in 1–50 kHz motor/solenoid control. For >100 kHz SMPS, lower-QG devices like Nexperia PMT100UN are better optimized.
