Product Features and Technical Specifications

The SM36C ESD protection diode offers several core technical advantages, ensuring outstanding performance in various high-speed data transmission applications. The key specifications are as follows:

VRWM (Maximum Reverse Working Voltage): 36V

VBR min (Minimum Breakdown Voltage): 40V

IR (Reverse Leakage Current): 1μA (at 25°C)

VC (Clamping Voltage): 60V (Maximum)

CJ (Junction Capacitance): 35pF

Package Type: SOT-23

These specifications enable the SM36C to meet the high-speed signal transmission needs of HDMI interfaces while providing effective ESD protection.

Efficient Protection Design Enhances System Stability

Electrostatic discharge (ESD) events typically occur when users interact with devices, such as touching the device or connecting peripherals. These external disturbances can enter the system through interface circuits, potentially causing component failure or even permanent damage. The SM36C ESD protection diode clamps the ESD voltage to safe levels, effectively preventing damage to sensitive components like HDMI chips. Its reverse leakage current is as low as 1μA, ensuring that normal signal integrity is not affected, while its clamping voltage can reach up to 60V, effectively limiting the peak voltage of electrostatic discharges.

Adaptable for Multiple Applications to Ensure Interface Safety

HDMI interfaces are not only widely used in consumer electronics but are also increasingly adopted in industrial, automotive, and medical devices. With the growing demand for 4K, 8K, and even higher resolution video transmission, data transfer rates and bandwidth requirements continue to rise, making interface interference immunity even more critical. The SM36C ESD protection diode is specifically designed to meet the demands of these high-performance environments.

In automotive infotainment systems, as autonomous driving technology and in-vehicle entertainment systems become more widespread, the need for HDMI interfaces to transmit large volumes of high-definition video signals is inevitable. The SM36C ESD protection diode effectively protects these interfaces from external static interference, ensuring stable operation of the in-car system. In medical devices, HDMI interfaces are often used for high-precision image transmission, which requires extremely high signal integrity. The SM36C provides reliable protection for these critical devices, reducing the risk of failure caused by electrostatic discharges.

Enhanced Design Flexibility and Automated Inspection

To meet the growing demand for smaller and more complex designs in modern automotive, industrial, and consumer electronics products, the SM36C ESD protection diode is available in multiple packaging options, offering great design flexibility. The compact SOT-23 package not only provides excellent thermal performance but also suits high-density integrated circuit designs. Additionally, the SM36C supports side soldering technology, allowing the device to be easily inspected by automated optical inspection (AOI) on production lines, improving manufacturing efficiency and reducing potential defects.

Conclusion

As high-speed data transmission becomes increasingly widespread in electronic devices, the need for ESD protection at interfaces has never been more important. Slkor's SM36C ultra-low junction capacitance ESD protection diode, with its outstanding electrical performance, low junction capacitance, and compact packaging, is poised to play a crucial role in a variety of high-speed data transmission applications. It will become an indispensable core component in ensuring the safety of HDMI interfaces and other sensitive data interfaces.
