1KSMB10

TVS (Transient Voltage Suppressors) – Diodes are widely used in many electrical applications that require protection against transient voltage spikes and overvoltage conditions. The common features of TVS – Diodes are: high peak pulse power capability, high surge current handling capability, fast response time, low capacitance, low clamping voltage, and good reliability. They are designed to limit the peak voltage across a connected circuit component or system by absorbing and dissipating the transient energy from the voltage spike or surge.

One of the many applications of TVS – Diodes is in suppressing system startup transients. When a power-up operation occurs, transient voltages can be generated that can potentially damage the circuit. TVS – Diodes can be used to absorb and dissipate this energy, thus protecting the circuit and preventing the transient from reaching its destination. TVS – Diodes can also protect against the effects of electromagnetic interference (EMI), which occurs when a system is subject to high frequencies and amplitudes of noise.

The 1KSMB10 is a popular device used for transient voltage protection. It is a silicon avalanche diode and has a Peak Pulse Power (PPP) rating of 800 Watts. It has a terminal capacitance of 4pF, and its typical reverse breakdown voltage is 5V. The 1KSMB10 is normally used in conjunction with a resistor and capacitor combination that helps to filter out any low-frequency, high-amplitude noise. The device can also be used in conjunction with a Zener diode to provide additional protection against EMI noise.

The working principle behind TVS – Diodes is relatively simple. When a transient voltage spike or surge enters the circuit, the voltage across the device increases quickly. This quick increase halts the current flow, which is known as the “clamping” action. The energy stored in the diode is then dissipated as heat, preventing further damage. This allows the device to protect the circuit from the damaging electrical effects of the transient.

TVS – Diodes are an effective and reliable protection solution for many electrical applications. The 1KSMB10 in particular is well-suited for suppressing system startup transients, providing protection against EMI noise, and limiting peak voltage across a connected circuit component or system. By understanding the working principle behind these devices, users can better utilize them for their protective needs.
