Product details
Overview
BUK7507-55B,127 from NXP Semiconductors is a standard-level N-channel TrenchMOS FET in TO-220AB (SOT78A) package, rated for 55 V drain-source voltage, 75 A continuous drain current at Tmb = 25 °C, and 175 °C junction temperature. It delivers 5.8 mΩ typical RDS(on) at VGS = 10 V and ID = 25 A, Tj = 25 °C, and is AEC-Q101 qualified for automotive critical power switching in 12 V/24 V systems.
For engineers reviewing the BUK7507-55B,127 datasheet, BUK7507-55B,127 pinout, BUK7507-55B,127 application, or BUK7507-55B,127 equivalent, this device supports thermally demanding automotive load control where low conduction loss, avalanche ruggedness (351 mJ), and gate-drive compatibility with standard 10 V logic are essential selection criteria.
Technical Context
This N-channel enhancement-mode MOSFET uses TrenchMOS technology to achieve low RDS(on) and high thermal robustness. Its gate threshold voltage ranges from 2 V to 4 V at 25 °C and remains functional down to 1 V at 175 °C, enabling reliable turn-on across automotive temperature extremes.
The device features an integrated source-drain diode with 0.85 V forward voltage at 40 A and 25 °C, and exhibits 62 ns reverse recovery time under defined test conditions. Its 0.74 K/W junction-to-mounting-base thermal resistance enables high-power dissipation when heatsink-mounted.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 55 V - Maximum blocking voltage compatible with 24 V automotive battery systems with transient margin. |
| ID (continuous) | 75 A at Tmb = 25 °C - Sustained load current capability limited by TO-220AB package thermal performance. |
| RDS(on) | 5.8 mΩ typ @ VGS = 10 V, ID = 25 A, Tj = 25 °C - Enables <1.5 W conduction loss at 25 A, reducing heatsink requirements. |
| EAS | 351 mJ non-repetitive avalanche energy - Supports unclamped inductive switching in motor/solenoid drive without external snubbers. |
| Tj max | 175 °C - Qualified for under-hood automotive environments with extended thermal margin over industrial-grade parts. |
| QGD | 17 nC - Gate-drain charge value directly impacts switching speed and Miller-effect-induced turn-off delay in hard-switched topologies. |
| Rth(j-mb) | 0.74 K/W - Low junction-to-mounting-base thermal resistance enables efficient heat transfer to external heatsink. |

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 |
|---|---|---|---|
| STP75NF55 | 55 V, 75 A, RDS(on) = 10.5 mΩ @ 10 V - higher on-resistance and no AEC-Q101 qualification. | Targeted at industrial/commercial power supplies, not automotive-qualified systems. | Select only if AEC-Q101 compliance is unnecessary and thermal margin permits higher conduction loss. |
| IRFZ44NPBF | 55 V, 49 A, RDS(on) = 28 mΩ @ 10 V - lower current rating, higher RDS(on), and no automotive qualification. | Suitable for cost-sensitive consumer or prototyping use, not production automotive designs. | Use only for non-safety-critical, low-duty-cycle applications where 75 A and 175 °C operation are not required. |
Compared with STP75NF55 and IRFZ44NPBF, the BUK7507-55B,127 provides superior thermal robustness (175 °C), lower conduction loss (5.8 mΩ vs ≥10.5 mΩ), and mandatory AEC-Q101 certification-making it the sole choice for volume automotive power switching where reliability and regulatory compliance are non-negotiable.

FAQ
Is BUK7507-55B,127 suitable for high-frequency PWM switching?
The device supports PWM operation up to ~100 kHz in practical automotive applications, with 24 ns turn-on delay, 52 ns rise time, 77 ns turn-off delay, and 41 ns fall time at standard test conditions. However, its 2820 pF input capacitance and 17 nC QGD mean gate drive strength must be sufficient to minimize switching losses-especially above 50 kHz in thermally constrained layouts.
What is the role of the mounting base in TO-220AB package?
The mounting base (mb) is electrically connected to the drain terminal and serves as the primary thermal interface to the heatsink. Its direct metal-to-die connection yields a low 0.74 K/W junction-to-mounting-base thermal resistance, enabling efficient heat extraction-critical for sustaining 75 A continuous current in automotive under-hood environments.
Does BUK7507-55B,127 include integrated ESD protection?
No. The device does not integrate dedicated ESD protection circuitry. Its gate oxide is rated for ±20 V maximum gate-source voltage, and gate leakage is specified at ≤100 nA at VGS = ±20 V. External gate protection (e.g., Zener clamps or RC snubbers) is recommended in systems exposed to automotive transients or handling risks.
Can BUK7507-55B,127 replace older NXP BUK7508-55B in existing designs?
Yes-BUK7507-55B,127 and BUK7508-55B share identical TO-220AB package, pinout, voltage rating (55 V), and AEC-Q101 qualification. The BUK7507-55B offers lower RDS(on) (5.8 mΩ vs 7.5 mΩ typ), improved thermal resistance (0.74 K/W vs 0.85 K/W), and higher avalanche energy (351 mJ vs 290 mJ), enabling direct drop-in replacement with enhanced efficiency and ruggedness.
