Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Under the wave of high-voltage new energy vehicles and the popularization of intelligent driving, transient voltage surges have become the primary threat to the failure of on-board electronic systems. Vishay has set the global benchmark for automotive transient suppression technology with its picosecond response, ultra-low clamping voltage and automotive-grade reliability. As a well-known supplier of electronic components, Shenzhen Mingjiada Electronics Co., Ltd. integrates Vishay's direct supply resources from the original factory and a dynamic inventory of hundreds of millions to create a one-stop supply platform covering the entire range of automotive-grade TVS systems including unidirectional, bidirectional, axial and surface mount. With 48-hour global delivery, scenario-based protection solutions and full life cycle support, Safeguard the electrical safety of every volt in the intelligent cockpit, the three-electricity system and the Internet of Vehicles.

I. Vishay TVS Technology Core: Redefining the Physical Limits of Electrical Protection

Nanosecond-level battlefield guards: The ultimate defense line for transient response

SMF series (such as SMF33A) : The response time is as fast as 1 ps, the clamping voltage is precisely locked at 53.3V (@IPP=38.6A), and the load impact energy of ISO 7637-2 is reduced by 98%.

Axial packaging flagship (such as 1.5KE series) : With a peak pulse power of up to 1500W and a surge current resistance of over 300A in 8/20μs, it serves as the "explosion-proof armor" for the BMS main control board.

2. Triple evolution of automotive-grade reliability

AEC-Q101 certification: The entire series has passed the extreme temperature cycling test ranging from -55℃ to 175℃ (such as the SMAJ series), and still maintains stable clamping characteristics at a junction temperature of 150℃.

Zero failure protection: Bidirectional TVS (such as V15AUMLA) achieves ±15kV ESD protection, meeting the highest anti-interference standard of IEC 61000-4-2 Level 4;

Miniaturization breakthrough: The size of SOD-923 packages (such as V8.5MLA) is only 1.0×0.6mm, and the power density is 10 times higher than that of traditional plug-ins.

3. Scenario-based protection matrix for intelligent systems

800V platform Guardian: SMC series (such as SMC58A) can withstand a maximum reverse turn-off voltage of 58V, building a safety barrier for silicon carbide electric drive systems.

Gigabit Ethernet Sentinel: The ESD9L series has a junction capacitance as low as 0.35pF, ensuring the integrity of 1000BASE-T1 signals for in-vehicle Ethernet.

Ii. Mingjiada Supply System: From Nanosecond Protection to Global-level Delivery

Dual guarantee of original factory traceability and dynamic inventory

100% traceable genuine products: Each TVS comes with Vishay's original laser code and AEC-Q101 certification documents, and supports X-ray packaging verification.

Billion-level spot pool: Shenzhen bonded warehouse always keeps over 2 million units of SMAJ/SMC and other scarce models in stock. Urgent orders of automotive-grade TVS can be directly dispatched to the world by air within 24 hours.

2. Empowerment through scenario-based protection design

The Mingjiada FAE team provides full-chain technical support

Three-electricity system protection kit: 800V battery pack protection solution based on SMC58CA, integrated multi-stage filter circuit design guide;

The golden rule of Ethernet ports: ESD9L series + common mode choke layout template, certified by CISPR 25 Class 5 Radiation;

Discontinued alternative solution: Seamless upgrade from the early P6KE series to the SMAJ series, with 100% PCB layout compatibility.

3. Full life cycle cost optimization

Price competitiveness: Relying on Vishay's strategic cooperation, the unit price of SMAJ33A per 10,000 units is as low as ¥0.28, reducing the procurement cost for automotive-grade products by 20%.

VMI inventory management: Materials can be called upon as needed. Slow-moving TVS can be purchased at a high price in reverse, reducing the occupation of customer funds.

Mingjiada Electronics, by integrating Vishay's original factory resources, a dynamic inventory of hundreds of millions, and cross-model protection solutions, builds an electrical safety closed loop for automakers from R&D to mass production. Whether it's dealing with ISO 16750 surge tests, CISPR 25 EMC certification, or high-voltage protection challenges, this is always your reliable supply hub for automotive-grade TVS.
