Littelfuse, a global leader in circuit protection solutions, recently introduced its P6SMB series of TVS diodes, which includes models such as P6SMB440A, P6SMB, P6SMB15A, P6SMB15CA, P6SMB36A, and P6SMB400CA. These diodes boast rapid response times and exceptional clamping capabilities, making them ideal for protecting sensitive electronic components. They respond in under 1 picosecond from 0V to BV min, ensuring they react swiftly to voltage transients. This makes the P6SMB series suitable for a variety of applications, including protecting I/O interfaces, safeguarding VCC buses, and offering defense for circuits in telecommunications, computers, industrial setups, and consumer electronics.
Designed specifically to shield equipment from voltage surges caused by lightning strikes and similar transient voltage events, the P6SMB series offers robust protection with its low incremental surge resistance. When the VBR min exceeds 12V, the typical leakage current remains below 1 microampere, with a response time under 1 picosecond. This ensures reliable and secure circuit protection.
The P6SMB series is available in a compact surface-mount package that optimizes board space usage. With a plastic package flammability rating of V-0, it is lead-free, halogen-free, RoHS compliant, and meets ESD standards as per IEC 61000-4-2. Additionally, these diodes feature a built-in strain relief function, allowing them to offer protection for data lines in compliance with IEC 61000-4-4.
The P6SMB series also boasts impressive performance specifications. For instance, it can handle peak pulse powers of up to 600W at a 10/1000μs waveform, with a duty cycle of 0.01%. The breakdown voltage reaches up to 30kV, and the breakdown voltage at various temperatures follows a predictable formula based on temperature coefficients.
Key features of the P6SMB series include:
- Breakdown voltage of up to 30kV for IEC-61000-4-2 ESD protection.
- Compliance with IEC 61000-4-2 for ESD protection.
- Data line protection according to IEC 61000-4-4 standards.
- Built-in strain relief functionality.
- Leakage current below 1μA when VBM min > 12V, with response times under 1ps.
- Peak pulse power handling of 600W at a 10/1000μs waveform.
- Temperature coefficient of approximately 0.1%.
In summary, the P6SMB series combines advanced protection features with high reliability, making it an essential component for modern electronic designs requiring robust transient voltage suppression.
Optical Cable Cross Connection Cabinet
Modular design of Optical Cable Cross Connection Cabinet(FDH,FOCC) provides the largest flexibility; satisfy the needs of the present and future development. The body using the stainless steel and surface using electrostatic spray so it has good corrosion resistance and anti-aging function, the wind protection class of the body achieves the IP66 level. The effect of defense dewing is excellent. The module tray can spin out of 90 degrees around the axis in the left front, and the bevel of the adapters within the module takes on 30 degrees. The clip-locked installation ensures the bending radius of the fiber directly and prevents the eyes from injury. Weld disk can spin out of 90 degrees, and then draw out, so it is convenient to construction, and also convenient to expansion and maintenance. Have doors in the front and back, have ample space for cabling, convenient to operation and maintenance. Have reliable device for fastness, peeling and grounding of the optical cables.
