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 |
|---|---|---|---|
| IPB070N05N3 G | 55 V VDS, 120 A ID, 7.0 mΩ RDS(on) @ 4.5 V; no integrated temperature sense diode; PG-HSOF-8 package. | Lacks junction temperature monitoring; requires external thermal protection circuitry in safety-critical EPAS. | Choose when board space is constrained and thermal monitoring is handled externally. |
| STL220N5LF8AG | 55 V VDS, 110 A ID, 6.5 mΩ RDS(on) @ 4.5 V; AEC-Q101 qualified; no integrated TSD; PowerFLAT 8x8 HV package. | Surface-mount alternative with lower profile but no on-die thermal sensing; higher RDS(on) increases conduction loss at 100+ A. | Prefer for automated assembly where TO-220 through-hole mounting is undesirable. |
Compared with BUK9907-55ATE,127, IPB070N05N3 G offers smaller footprint but forfeits integrated thermal monitoring, while STL220N5LF8AG provides SMT compatibility at the cost of higher on-resistance and absence of TSD-making BUK9907-55ATE,127 uniquely suited for thermally managed automotive power stages.

FAQ
What is the maximum continuous drain current rating for BUK9907-55ATE,127?
The BUK9907-55ATE,127 supports 140 A continuous drain current at Tmb = 25 °C, limited by package thermal capacity. At Tmb = 100 °C, the rating drops to 75 A per Figure 2 in the datasheet. This derating behavior is critical for thermal design in enclosed EPAS housings where mounting base temperature exceeds ambient.
Does BUK9907-55ATE,127 include integrated electrostatic discharge (ESD) protection?
Yes, BUK9907-55ATE,127 incorporates TrenchPLUS diodes that provide 6 kV Human Body Model (HBM) ESD protection on pins 1 (gate), 3 (drain), and 5 (source), as confirmed in Table 4 of the datasheet. This eliminates the need for external TVS devices in most automotive board-level ESD protection schemes.
How is the temperature-sense diode in BUK9907-55ATE,127 used in practice?
The BUK9907-55ATE,127 features a calibrated temperature-sense diode (TSD) between pins 2 (anode) and 4 (cathode) with −1.54 mV/K coefficient. By injecting 250 µA and measuring forward voltage (VF = 658 mV @ 25 °C), microcontrollers calculate junction temperature with ±2 °C accuracy-enabling dynamic current derating in BUK9907-55ATE,127-based inverters.
Is BUK9907-55ATE,127 qualified to AEC-Q101 standards?
Yes, BUK9907-55ATE,127 is explicitly designed and qualified to AEC-Q101 for automotive critical applications, as stated in Section 1.1 of the product data sheet. This includes stress testing for temperature cycling, humidity, mechanical shock, and ESD-validating its use in EPAS, power distribution, and other safety-relevant systems.
What is the thermal resistance from junction to mounting base for BUK9907-55ATE,127?
The BUK9907-55ATE,127 has a maximum thermal resistance Rth(j-mb) of 0.55 K/W from junction to mounting base, per Table 5. This low value reflects direct die-to-heatsink conduction via the metal mounting base (pin 3), making it essential to use thermally conductive mounting hardware and thermal interface material for optimal performance.
