In various automotive application scenarios such as powertrain systems, battery management, motor drives, and onboard chargers, Infineon's IPD30N12S3L-31, with its AEC Q101 certification, high reliability, and excellent performance, has been a preferred choice for engineers worldwide. However, in the post-pandemic era with intensified global supply chain disruptions and trade frictions, this imported component faces challenges: unstable lead times, procurement costs affected by exchange rates, and lagging technical support. These issues constrain production schedules and cost control for downstream companies. Given this demand, domestic substitution has become a necessity, crucial for ensuring supply chain security, reducing costs, and enhancing competitiveness.
VBsemi, with deep expertise in power semiconductors, launches the VBGE1121N N-channel power MOSFET based on independent R&D. This product directly对标s the IPD30N12S3L-31, offering parameter upgrades, technological parity, and full package compatibility. It can serve as a direct replacement without circuit modifications, providing a more stable, cost-effective, and locally attuned solution for automotive electronic systems.
Comprehensive Parameter Surpassing, Ample Performance Redundancy, Adapting to More Demanding Conditions.
Tailored as a domestic alternative to the IPD30N12S3L-31, the VBGE1121N achieves leapfrog improvements in key electrical parameters:
Firstly, the drain-source voltage remains at 120V, matching the original model, ensuring compatibility in automotive voltage environments.
Secondly, the continuous drain current is increased to 60A, doubling the original model's 30A—a 100% enhancement in current-carrying capability. This enables handling of higher power demands, improving system stability and enabling upgrades to higher-performance designs.
Thirdly, the on-state resistance is as low as 11.5mΩ (@10V gate drive), significantly lower than the IPD30N12S3L-31's 31mΩ. This reduction minimizes conduction losses, improving efficiency and reducing heat generation, critical for automotive thermal management.
Additionally, the VBGE1121N supports a ±20V gate-source voltage, offering robust gate ESD and noise immunity, preventing unintended turn-on in harsh electromagnetic environments. The 3V gate threshold voltage balances drive convenience and switching reliability, compatible with mainstream automotive driver ICs without circuit adjustments.
Enhanced with Advanced SGT Technology, Reliability and Stability Inherited and Upgraded.
The core advantage of the IPD30N12S3L-31 lies in its AEC Q101 certification and reliability for automotive applications. The VBGE1121N employs Shielded Gate Transistor (SGT) technology, optimizing switching characteristics and device reliability. It undergoes 100% avalanche testing and high-voltage screening, ensuring excellent avalanche energy performance for handling surges in automotive systems. Through optimized capacitance design, it reduces switching losses and enhances dv/dt tolerance, suitable for high-frequency switching in automotive environments. The device operates over a wide temperature range, up to 175°C, and passes rigorous automotive-grade reliability tests, ensuring long-term performance in demanding conditions like engine compartments and extreme climates.
Fully Compatible Package, Enabling "Plug-and-Play" Replacement.
For downstream enterprises, the VBGE1121N addresses replacement concerns through package design. It uses a TO-252 package, identical to the IPD30N12S3L-31 in pinout, dimensions, and thermal structure. Engineers can replace it directly without PCB modifications or thermal redesign, achieving "plug-and-play" convenience. This compatibility reduces verification time to 1-2 days, avoids additional costs from design changes, and accelerates time-to-market.
