Product details
Overview
SQD40061EL-T4_GE3 from Vishay Siliconix is an automotive-grade P-channel enhancement-mode MOSFET designed for high-current, high-temperature switching in power distribution and load management circuits. It features a -40 V drain-source voltage rating, 0.0051 Ω RDS(on) at VGS = -10 V, 100 A continuous drain current capability at TC = 25 °C, and AEC-Q101 qualification - enabling use in 12 V/24 V vehicle body electronics such as smart fuses and reverse polarity protection.
For engineers reviewing the SQD40061EL-T4_GE3 datasheet, SQD40061EL-T4_GE3 pinout, SQD40061EL-T4_GE3 application, or SQD40061EL-T4_GE3 equivalent, this page delivers verified technical context, thermal performance data, TO-252 package layout, and validated alternative options for automotive power system design.
Technical Context
This P-channel MOSFET uses Vishay's TrenchFET® process to achieve low on-resistance and robust avalanche energy handling (84 mJ). Its gate threshold voltage range of -1.5 V to -2.5 V enables reliable turn-on with standard 3.3 V or 5 V logic-level control in high-side switch configurations.
The device integrates a fast-recovery body diode (trr = 59–120 ns, Qrr = 90–180 nC) and is 100 % Rg and UIS tested. Thermal resistance is optimized with RthJC = 1.4 °C/W and RthJA = 50 °C/W (1" × 1" FR4 PCB), supporting operation up to +175 °C junction temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRF4905PbF | RDS(on) = 0.02 Ω @ -10 V (4× higher); Qg = 110 nC; not AEC-Q101 qualified | Lower current density and no automotive qualification limit use to non-safety-critical industrial controls | Select only if cost sensitivity outweighs thermal efficiency and automotive compliance requirements |
| STP40PF06 | RDS(on) = 0.014 Ω @ -10 V; TJ max = +175 °C; AEC-Q101 qualified; TO-220 package | Larger through-hole footprint and higher RthJA (65 °C/W) reduce power density and require mechanical mounting | Prefer when legacy board layout or heatsink compatibility favors TO-220, but expect ~2.7× higher conduction loss vs. SQD40061EL-T4_GE3 |
Compared with IRF4905PbF and STP40PF06, SQD40061EL-T4_GE3 delivers the lowest RDS(on) in TO-252, highest current density per mm², and full AEC-Q101 validation - making it optimal for space-constrained, thermally demanding automotive high-side switches where efficiency and reliability are co-prioritized.

FAQ
What is the maximum continuous drain current for SQD40061EL-T4_GE3 at 125 °C case temperature?
The SQD40061EL-T4_GE3 supports -60 A continuous drain current at TC = 125 °C, as specified in its Absolute Maximum Ratings table. This derating reflects thermal limits of the TO-252 package and silicon die; actual usable current depends on PCB layout, ambient temperature, and airflow. The SQD40061EL-T4_GE3 maintains RDS(on) ≤ 0.0079 Ω at this condition, ensuring predictable conduction loss.
Is SQD40061EL-T4_GE3 suitable for high-side switch applications with 3.3 V microcontroller control?
Yes - the SQD40061EL-T4_GE3 has a gate threshold voltage range of -1.5 V to -2.5 V, allowing full enhancement with -3.3 V or -5 V gate drive. However, to achieve its rated RDS(on) of 0.0051 Ω, a -10 V gate-source voltage is required; thus, a dedicated gate driver or charge pump is recommended for logic-level control. The SQD40061EL-T4_GE3 is commonly deployed in such configurations within automotive BCMs.
Does SQD40061EL-T4_GE3 include integrated ESD protection on the gate?
No - the SQD40061EL-T4_GE3 does not integrate gate ESD protection diodes. Its gate oxide is rated for ±20 V VGS, and the datasheet specifies 100 % Rg testing to verify gate robustness, but external gate resistors (e.g., 10–100 Ω) and TVS clamping are recommended in automotive environments. This design choice preserves switching speed and is consistent with Vishay's TrenchFET® high-performance strategy for the SQD40061EL-T4_GE3.
What is the safe operating area (SOA) limitation for SQD40061EL-T4_GE3 in linear mode?
The SQD40061EL-T4_GE3 SOA curve (Figure 6, datasheet page 5) shows that linear-mode operation is limited by RDS(on) at short durations (<10 ms) and by package thermal resistance at longer pulses. At DC, the device is restricted to ≤35 W (TC = 125 °C), corresponding to ~59 A at VDS = -0.6 V. For sustained analog regulation, derating below 20 W is advised. The SQD40061EL-T4_GE3 is optimized for switching, not linear operation.
How does the body diode performance of SQD40061EL-T4_GE3 compare to standard rectifiers in freewheeling applications?
The SQD40061EL-T4_GE3 body diode exhibits VSD = -0.84 to -1.5 V at -30 A and trr = 59–120 ns, outperforming many discrete Schottky diodes in recovery speed while matching forward drop at moderate currents. Its Qrr of 90–180 nC minimizes stored charge loss during commutation. In buck or flyback topologies, this enables efficient synchronous rectification without external diode replacement - a key advantage of the SQD40061EL-T4_GE3 in compact automotive power stages.
