TVS- Diodes: MMBZ10VAL,215 application field and working principle

TVS (Transient voltage suppressor) diodes, also recognized as transil or civil diodes, are specifically designed to protect power supply, input/output lines, and other electronic devices from damaging effects of electrical overstress (EOS). This kind of protection is essential for today’s electric systems, especially those with thin connections, in order to maintain high system reliability and performance. Among TVS diodes, the MMBZ10VAL,215 is a bidirectional zener diode with a specified 600 Watt peak pulse power limit.

Application of MMBZ10VAL, 215

The MMBZ10VAL,215 has multiple applications. It can be used as general-purpose enable/reset switches, as an over current protection for transmission lines, and as an overload protection device in power lines. It is often used for protection from electrical overstress (EOS) related to the modem line, ESD, and lightning surge. Its ability to prevent a wide range of voltage transients in both voltage and pulse power makes it an ideal device for protecting modern electronic equipment from these kind of damages.

Working principle of MMBZ10VAL,215

The MMBZ10VAL,215 is a bidirectional zener diode. This means that if there is an excessive voltage on either side, the diode will switch off to protect the circuit from any damage. The current-voltage characteristics of the diode are asymmetric, which helps in providing higher reverse voltage suppression. It operates in the avalanche mode with a breakdown voltage of 8.2V that is near the zener breakdown voltage. When the voltage exceeding the zener breakdown voltage, the diode enters into the breakdown region. It helps to reduce the voltage and releases energy stored in the device due to the reverse breakdown current. Since the energy stored in the breakdown process is very low, the TVS diode does not cause any damages to the circuits.

Advantages of the MMBZ10VAL,215

• Low power dissipation
• Lower leakage current

The MMBZ10VAL,215 is a low-cost and efficient solution for protecting electronic circuits from overvoltage transients. In summary, the MMBZ10VAL,215 is a diode specifically designed to protect power supplies, input/output lines, and other electronic devices from the destructive effects of EOS. It is highly thermally and temperature stable, and has a peak pulse power limit of 600W.
