⚡Overview
The SESMC24 ESD Protection Diode is a high-performance circuit protection device developed by Semiware, specifically designed for CAN bus and sensitive electronic circuits. With excellent transient suppression capability, it effectively guards against electromagnetic interference such as electrostatic discharge (ESD) and electrical fast transients (EFT), ensuring signal integrity and system reliability in harsh environments. Its compact SOT-23 package makes it ideal for space-constrained, high-density circuit designs, providing robust overvoltage protection for industrial control, automotive electronics, and communication equipment.
💡Advantages of SESMC24
The SESMC24 ESD protection diode is specifically engineered for 24V low-voltage systems, achieving an optimal balance between robust protection and signal integrity:
- Operating Voltage Range: Features a reverse working voltage (V₍RWM₎) of 24V, making it ideal for CAN bus and other communication lines. Maintains high impedance during normal operation to prevent signal interference.
- Reliable Overvoltage Protection: Minimum breakdown voltage (V₍BR₎) ≥26.7V (tested at 1mA), providing safety margin against voltage fluctuations. Excellent clamping performance with ≤43V at 1A and ≤52V at 7A, ensuring fast surge suppression to protect downstream ICs.
- Low-Power Design: Ultra-low reverse leakage current (I₍R₎) ≤1μA minimizes standby power consumption, extending battery life in portable devices.
- High-Speed Signal Compatibility: Junction capacitance (C₍J₎) ≤50pF minimizes signal attenuation, supporting high-speed interfaces like USB and serial ports.
🚀IEC Compatibility
The SESMC24 delivers certified protection against transient threats, validated by rigorous international standards:
- IEC 61000-4-2 (ESD) Compliance:
±15kV air discharge / ±8kV contact discharge protection
Effectively safeguards against human-body ESD and equipment friction discharges - IEC 61000-4-4 (EFT) Endurance:
Withstands 40A surge current (5/50ns)
350W peak pulse power (8/20μs) capability
📊 Conclusion
The SESMC24 ESD Protection Diode delivers a precision transient voltage solution for CAN bus and multi-line systems with three key advantages: 24V operating voltage, ultra-low power consumption, and compact SOT-23 packaging. Specifically optimized for demanding CAN communication environments, it ensures signal integrity with ultra-low junction capacitance (≤50pF) and nanosecond-level response. The solution provides comprehensive protection coverage for consumer electronics interfaces and industrial equipment ports, making it the reliable choice for safeguarding data transmission continuity.
