Amid the accelerating wave of automotive electrification and the strategic push for supply chain independence, domestic substitution of core power semiconductors has transitioned from a contingency plan to a critical necessity. For low-voltage, high-reliability applications in automotive systems, identifying a locally sourced, performance-competitive, and supply-stable alternative is a key challenge for automakers and Tier‑1 suppliers. Focusing on the widely adopted 60V TrenchFET MOSFET from VISHAY — the SQ2361CES‑T1‑GE3 — the VB2610N from VBsemi stands out as a superior replacement. It not only matches the essential qualifications but achieves a significant leap in key performance metrics, transforming the substitution from "feasible" to "exceptional," and from "replacement" to "upgrade."
I. Parameter Comparison and Performance Leap: Core Advantages Delivered by Advanced Trench Technology
The SQ2361CES‑T1‑GE3 has been valued in automotive low‑voltage switching applications for its 60V drain‑source voltage, 2.8A continuous current, AEC‑Q101 qualification, and 100% Rg and UIS testing. However, evolving demands for lower losses and higher current handling call for improved electrical characteristics.
1. Building on the same 60V VDS rating, AEC‑Q101 compliance, and compact SOT23‑3 package, the VB2610N leverages advanced Trench technology to deliver decisive enhancements:
Drastically Reduced On‑Resistance: With VGS = 10V, RDS(on) is as low as 70mΩ — a reduction of over 60% compared to the 177mΩ of the reference part. This dramatically lowers conduction losses (Pcond = I_D²·RDS(on)), improving efficiency and reducing thermal stress.
Higher Current Capability: The continuous drain current rating is raised to 4.5A, an increase of over 60%, enabling support for more demanding load conditions without derating.
Robust Gate and Threshold Characteristics: With a VGS rating of ±20V and a well‑controlled threshold voltage Vth of -1.7V, the device ensures reliable operation and strong noise immunity in harsh automotive environments.
II. Expanding Application Scenarios: From Pin‑to‑Pin Replacement to System Enhancement
The VB2610N is a direct drop‑in replacement in existing designs using the SQ2361CES‑T1‑GE3, while its performance advantages enable system‑level improvements:
1. Automotive Low‑Voltage Power Distribution & Switching
Ideal for load switches, power window controls, lighting drivers, and sensor power management. Lower RDS(on) reduces voltage drop and power loss, enhancing overall electrical efficiency.
2. DC‑DC Converter Modules & POL (Point‑of‑Load) Converters
The improved efficiency and current capability support higher power density and cooler operation in 12V/24V battery‑based conversion stages, contributing to longer system life.
3. Motor Drive Auxiliaries & Solenoid/Valve Control
Suitable for small motor drives (e.g., fans, pumps) and precise actuator control in body and comfort systems, offering higher reliability and smoother operation due to reduced losses.
4. Industrial & Consumer Power Management
Applications such as portable devices, power tools, and low‑voltage industrial switches benefit from the combination of high efficiency, robust package, and automotive‑grade reliability.
III. Beyond Specifications: Reliability, Supply Chain Assurance, and Lifecycle Value
Choosing the VB2610N is both a technical and strategic decision:
1. Secure Domestic Supply Chain
VBsemi controls the full process from chip design to packaged testing, ensuring stable supply, predictable lead times, and resilience against global market fluctuations, safeguarding production continuity for customers.
2. Total Cost Advantage
With superior performance parameters, the VB2610N offers a highly competitive cost structure, reducing BOM expenses while elevating system performance, thereby increasing end‑product value.
3. Localized Technical Support
Rapid, full‑cycle support — from selection, simulation, and testing to failure analysis — accelerates design‑in, optimizes system performance, and resolves issues efficiently, shortening time‑to‑market.
IV. Replacement Guidance and Implementation Path
For designs currently using or considering the SQ2361CES‑T1‑GE3, the following steps are recommended for a smooth transition:
1. Electrical Performance Validation
Compare key switching waveforms, loss distribution, and efficiency under the same circuit conditions. The VB2610N’s lower RDS(on) may allow for optimized gate drive settings to further enhance performance.
2. Thermal and Layout Assessment
Due to significantly reduced conduction losses, thermal stress is lowered. Evaluate potential simplifications in thermal management or opportunities for higher power density within the same footprint.
3. Reliability and System Validation
Conduct rigorous electrical, thermal, and environmental stress tests followed by system‑level and application‑specific validation to ensure long‑term reliability under real operating conditions.
