Product details
Overview
BUK7524-55 from NXP Semiconductors (formerly Philips) is an N-channel enhancement-mode TrenchMOS™ power transistor in TO220AB package, rated for 55 V drain-source voltage, 45 A DC drain current at 25 °C, and 24 mΩ RDS(ON) at VGS = 10 V. It integrates ESD protection up to 2 kV and is designed for automotive and general-purpose switching applications such as motor control and power supply load switching.
For engineers reviewing the BUK7524-55 datasheet, BUK7524-55 pinout, BUK7524-55 application, or BUK7524-55 equivalent, key selection criteria include its standard-level gate drive compatibility (10 V), low on-resistance with thermal derating, integral body diode performance, and TO220AB mounting-base thermal path for high-power dissipation.
Technical Context
The BUK7524-55 employs trench-gate MOSFET technology to achieve low RDS(ON) and high current capability while maintaining robust avalanche energy rating (80 mJ unclamped). Its gate threshold voltage ranges from 2.0 V to 4.0 V at 25 °C, enabling reliable turn-on with standard logic-level drivers.
Thermal design is enabled by a junction-to-mounting-base thermal resistance of 1.45 K/W (max), supporting heatsink attachment via the drain-connected tab. The device features a built-in body diode with 0.95–1.2 V forward voltage at 25 A and 40 ns reverse recovery time under specified conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 55 V maximum - defines maximum blocking voltage in switching circuits without breakdown risk |
| ID (DC) | 45 A at Tmb = 25 °C - usable continuous current with adequate heatsinking |
| RDS(ON) | 24 mΩ max at VGS = 10 V - determines conduction loss and junction temperature rise under load |
| Ptot | 103 W at Tmb = 25 °C - total power dissipation limit before thermal shutdown or damage |
| Tj | 175 °C maximum operating junction temperature - sets upper thermal boundary for reliability |
| ESD Rating | 2 kV HBM - enables handling without external ESD protection in assembly environments |
| Qrr | 0.07 µC typical - quantifies reverse recovery charge affecting switching losses in inductive loads |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP55NF06L | 60 V VDS, 55 A ID, 14 mΩ RDS(ON), TO-220FP package (isolated tab) | Higher voltage margin but lower thermal resistance to ambient; no integral ESD diode | Preferred where higher VDS margin or isolated tab is required; requires external gate protection |

FAQ
What is the maximum gate-source voltage rating for the BUK7524-55?
The BUK7524-55 has a maximum gate-source voltage rating of ±16 V. Exceeding this value risks permanent gate oxide damage. Designers should ensure gate drive circuits clamp VGS within this range, especially during switching transients or when using bootstrap configurations. The BUK7524-55 gate threshold voltage is 2.0–4.0 V at 25 °C, making it compatible with standard 10 V logic-level drivers.
Can the BUK7524-55 be used in high-temperature environments like under-hood automotive applications?
Yes, the BUK7524-55 supports junction temperatures up to 175 °C and storage temperatures from –55 °C to +175 °C. Its RDS(ON) increases predictably with temperature (normalized to 25 °C), and thermal resistance junction-to-mounting-base is specified at 1.45 K/W max. When mounted on an appropriately sized heatsink, the BUK7524-55 meets requirements for under-hood engine control modules and body electronics.
Does the BUK7524-55 have a built-in body diode, and what are its key characteristics?
Yes, the BUK7524-55 includes an integral body diode with forward voltage of 0.95–1.2 V at 25 A and reverse recovery time of 40 ns under specified test conditions (IF = 40 A, –dIF/dt = 100 A/µs). Its reverse recovery charge is 0.07 µC typical. These parameters make the BUK7524-55 suitable for freewheeling and synchronous rectification where low Qrr reduces switching losses.
What is the avalanche energy rating of the BUK7524-55, and how is it tested?
The BUK7524-55 is rated for 80 mJ of non-repetitive unclamped inductive turn-off energy (WDSS) at Tmb = 25 °C, ID = 40 A, VDD ≤ 25 V, VGS = 10 V, and RGS = 50 Ω. This rating is validated per the test circuit shown in Figure 16 of the datasheet and confirms ruggedness against inductive kickback in motor and solenoid drives. The BUK7524-55 does not specify repetitive avalanche capability.
Is the BUK7524-55 pin-compatible with other TO220AB MOSFETs, and what precautions apply to its mounting tab?
The BUK7524-55 uses standard TO220AB (SOT78) pinout: pin 1 = gate, pin 2 = drain, pin 3 = source, with the metal tab electrically connected to pin 2 (drain). While mechanically compatible with TO220AB footprints, electrical isolation of the tab must be verified per circuit topology-e.g., insulating washers are required if the heatsink is grounded. Unlike TO-220FP variants, the BUK7524-55 tab is not isolated.
