Product details
Overview
SQJ488EP-T2_BE3 from Vishay Siliconix is an automotive-grade N-channel 100 V MOSFET in PowerPAK® SO-8L package, delivering RDS(on) = 21.0 mΩ at VGS = 10 V and 25.8 mΩ at VGS = 4.5 V, rated for continuous drain current up to 42 A at TC = 25 °C, and qualified to AEC-Q101 for under-hood powertrain and body control modules.
For engineers reviewing the SQJ488EP-T2_BE3 datasheet, SQJ488EP-T2_BE3 pinout, SQJ488EP-T2_BE3 application, or SQJ488EP-T2_BE3 equivalent, key selection criteria include its 175 °C junction temperature rating, 100 % Rg and UIS tested reliability, low gate charge (Qg = 18–27 nC), and thermal resistance RthJC = 1.8 °C/W for high-efficiency DC-DC and motor drive designs.
Technical Context
This MOSFET employs TrenchFET® technology to achieve low on-resistance with fast switching performance, supporting high-frequency synchronous rectification and PWM-controlled loads. Its gate threshold voltage (VGS(th) = 1.5–2.5 V) enables robust 3.3 V and 5 V logic-level drive compatibility while maintaining tight parametric control across temperature.
The device features a single N-channel configuration with integrated source-drain diode (VSD = 0.78–1.2 V at IF = 4.7 A), optimized for bidirectional current handling in H-bridge motor drivers and reverse-polarity protection circuits where avalanche energy rating (EAS = 1.68 mJ) and pulsed current capability (IDM = 170 A) are critical.

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRF4905PbF | Higher RDS(on) (20 mΩ @ 10 V but only at TJ = 25 °C), no AEC-Q101 qualification, TO-220 package | Limited to non-automotive industrial use; requires heatsink due to higher RthJA | Choose IRF4905PbF only for cost-sensitive non-automotive prototypes where qualification and thermal density are not required. |
| STL220N6F7 | 60 V rating, lower RDS(on) (1.6 mΩ), but not AEC-Q101 qualified and uses PowerFLAT 8x8 package | Not suitable for 48 V+ systems; lacks automotive reliability validation and high-temp operation | Select STL220N6F7 only for 24 V battery-powered tools or consumer devices where voltage headroom and qualification are secondary. |
Compared with IRF4905PbF and STL220N6F7, the SQJ488EP-T2_BE3 uniquely combines 100 V rating, AEC-Q101 qualification, 175 °C operation, and PowerPAK SO-8L's low-inductance layout - making it the only drop-in option for production automotive 48 V power stages requiring zero layout rework and full compliance.

FAQ
What is the maximum junction temperature rating for SQJ488EP-T2_BE3?
The SQJ488EP-T2_BE3 is rated for continuous operation up to +175 °C junction temperature, verified per AEC-Q101 stress testing. This rating is explicitly confirmed in the Absolute Maximum Ratings table and supported by normalized RDS(on) vs. TJ curves showing stable performance across -55 °C to +175 °C. The SQJ488EP-T2_BE3 maintains functional integrity in under-hood environments where ambient temperatures exceed 125 °C.
Is SQJ488EP-T2_BE3 qualified for automotive applications?
Yes, SQJ488EP-T2_BE3 is AEC-Q101 qualified, as stated in the Features section and validated through full stress test suites including high-temperature operating life (HTOL), temperature cycling (TC), and unclamped inductive switching (UIS). The datasheet notes "Parametric verification ongoing" for certain tests, but qualification status is confirmed in Vishay's official product summary and ordering documentation. SQJ488EP-T2_BE3 meets automotive reliability requirements for powertrain and body electronics.
What is the gate threshold voltage range for SQJ488EP-T2_BE3?
The gate threshold voltage (VGS(th)) for SQJ488EP-T2_BE3 is specified as 1.5 V minimum, 2.0 V typical, and 2.5 V maximum at VDS = VGS and ID = 250 μA. This range ensures reliable turn-on with standard 3.3 V and 5 V logic-level drivers while providing noise immunity against spurious gate triggering. The SQJ488EP-T2_BE3 exhibits minimal VGS(th) drift over temperature, as shown in the Threshold Voltage vs. Junction Temperature graph.
Does SQJ488EP-T2_BE3 have an integrated body diode?
Yes, SQJ488EP-T2_BE3 includes an inherent N-channel MOSFET body diode with forward voltage VSD = 0.78–1.2 V at IF = 4.7 A and VGS = 0 V. This diode is fully characterized in the Source-Drain Diode Ratings section and supports freewheeling, reverse-current conduction, and bootstrap charging in half-bridge configurations. The SQJ488EP-T2_BE3 body diode is rated for pulsed current up to 128 A (ISM), enabling robust operation in motor drive and converter applications.
What is the thermal resistance from junction to case for SQJ488EP-T2_BE3?
The junction-to-case (drain) thermal resistance (RthJC) for SQJ488EP-T2_BE3 is 1.8 °C/W, measured under standard test conditions with the drain paddle soldered to a 1" × 1" FR-4 PCB. This value is listed in the Thermal Resistance Ratings table and reflects the dominant thermal path through the exposed drain terminal. The SQJ488EP-T2_BE3 achieves this low RthJC via its PowerPAK SO-8L package's large copper paddle, enabling efficient heat transfer to heatsinks or thermal vias.
