Product details
Overview
SQS462EN-T1_BE3 from Vishay Siliconix is an automotive-grade N-channel 60 V MOSFET in PowerPAK® 1212-8 package, delivering RDS(on) = 0.063 Ω at VGS = 10 V and 8 A continuous drain current at TC = 125 °C. It features AEC-Q101 qualification, 100 % Rg and UIS testing, and operates up to +175 °C junction temperature - ideal for high-reliability engine control, transmission, and body electronics switching.
For engineers reviewing the SQS462EN-T1_BE3 datasheet, SQS462EN-T1_BE3 pinout, SQS462EN-T1_BE3 application, or SQS462EN-T1_BE3 equivalent, key selection criteria include its 4.5 V gate drive capability (RDS(on) = 0.082 Ω), low 81 °C/W RthJA on FR4 PCB, and leadless PowerPAK 1212-8 thermal performance enabling compact, high-current automotive power stages.
Technical Context
This device uses TrenchFET® technology to achieve low on-resistance and fast switching with Qg = 8–12 nC and Ciss = 374–470 pF at VDS = 25 V. Its gate threshold voltage (VGS(th) = 1.5–2.5 V) ensures robust turn-on under automotive battery transients while maintaining low leakage (IDSS ≤ 150 μA at 175 °C).
The PowerPAK 1212-8 package exposes the drain pad on the bottom side for direct thermal conduction, achieving RthJC = 4.5 °C/W - critical for sustained 8 A operation in space-constrained engine bay modules without heatsinks.

FAQ
What is the maximum junction temperature rating for SQS462EN-T1_BE3?
The SQS462EN-T1_BE3 has a specified operating junction temperature range of −55 °C to +175 °C, fully qualified per AEC-Q101 for automotive under-hood applications. This rating is validated through accelerated life testing and thermal cycling, ensuring reliability in environments such as engine control units where ambient temperatures exceed 125 °C.
Does SQS462EN-T1_BE3 support 5 V logic-level gate drive?
Yes, SQS462EN-T1_BE3 is fully compatible with 5 V logic-level gate drive: its RDS(on) is specified at 0.082 Ω with VGS = 4.5 V, and gate threshold voltage (VGS(th)) ranges from 1.5 V to 2.5 V. This ensures robust turn-on using standard 5 V microcontrollers without requiring level-shifting circuitry.
What is the thermal resistance from junction to case (RthJC) for SQS462EN-T1_BE3?
The SQS462EN-T1_BE3 has a junction-to-case (drain) thermal resistance of 4.5 °C/W, measured from die junction to the exposed drain pad on the bottom of the PowerPAK 1212-8 package. This low value enables efficient heat transfer directly into the PCB copper, supporting 8 A continuous operation without external heatsinks.
Is SQS462EN-T1_BE3 suitable for inductive load switching with flyback energy?
Yes, SQS462EN-T1_BE3 is 100 % tested for Unclamped Inductive Switching (UIS), with a single-pulse avalanche energy rating of 4 mJ and IAS = 9 A. This makes it suitable for driving solenoids, relays, and fuel injectors where stored inductive energy must be safely absorbed without external protection components.
What is the gate charge profile of SQS462EN-T1_BE3 and how does it affect switching performance?
SQS462EN-T1_BE3 has a total gate charge (Qg) of 8–12 nC at VGS = 10 V, with Qgs = 1.3 nC and Qgd = 1.6 nC. This low Qgd/Qg ratio minimizes Miller effect, enabling clean switching transitions and reduced EMI - critical for high-frequency PWM control in automotive power stages.
