A Transient Voltage Suppression (TVS) diode, such as 824540850, is an electronic device designed to protect against transient overvoltages in electronic circuits. These transients can be caused by static electricity, surges, and lightning strikes, and can cause catastrophic system damage if not addressed properly. TVS diode can be used to protect subsystems, such as power supplies and data lines, from these transients.

The 824540850 TVS diode is a bidirectional device designed for transient voltage protection in automotive and industrial environments, specifically for 12V systems. It has a peak pulse power rating of 600W at a 10/1000µs pulse width, an ESD protection level of up to 25kV on I/O lines, and an operating junction temperature of -40°C to +125°C. Its reverse breakdown voltage is 14V, and the maximum clamp voltage is 27V. The diode is constructed from silicon and is AEC-Q101 compliant.

The working principle of a TVS diode is fairly simple. A TVS diode is connected in parallel across a circuit’s power supply. When a transient voltage (such as an ESD spike) is applied to the power supply, the reverse breakdown voltage of the TVS diode is exceeded, allowing current to flow from the transient voltage source to ground. This diverts the transient voltage away from the protected circuit and prevents it from damaging the circuit.

The 824540850 is an ideal solution for protecting 12V systems from transient overvoltages. Its robust design and wide temperature range make it suitable for automotive and industrial environments, while its capacitance characteristics make it ideal for data line protection. When combined with a transient voltage suppression circuit, the 824540850 can be used to protect a wide variety of circuits from destructive transients.
