5.0SMCJ24ATR

TVS (or transient voltage suppressor) diodes are highly effective components designed to protect electronic circuits from transients, or “spikes” in voltages. The 5.0SMCJ24ATR is one such device, widely used in industrial, commercial, and automotive applications. In this article, we’ll discuss the application field and working principle of the 5.0SMCJ24ATR.

Applications

The 5.0SMCJ24ATR is commonly used to protect against overvoltage transients in automotive systems, power supplies, industrial systems, and general purpose equipment. It is also ideal for protecting against electrostatic discharge (ESD) events, when properly inserted in an ESD protection circuit. It has a very fast response time and clamping voltage of 28 Volts (at 10 Amps), making it well-suited for protecting voltage-sensitive components.

The 5.0SMCJ24ATR can be used in a wide range of applications, from automobiles to servers. It is very popular in automotive electronics, where it is used to protect circuits from high-voltage spikes caused by the spark plugs or power surges. Its quick response time is also beneficial when protecting against ESD events, which can cause electrical damage in sensitive devices.

The 5.0SMCJ24ATR is particularly well-suited for applications that require temporary voltage and current protection, such as in power supplies. The device can be used in both AC and DC power supplies, as well as in switching mode power supplies. It is also frequently deployed in applications such as motor drives, medical electronics, and telecommunication equipment.

Operation Principle

The 5.0SMCJ24ATR is a diode-based device that works by clamping the voltage to the rated limit. When the voltage across the device reaches or exceeds its breakdown voltage—which is typically 28 Volts—the diode starts to conduct and restricts the voltage to the clamping voltage, while briefly allowing a very high amount of current to flow through it. The 5.0SMCJ24ATR has an average clamping voltage of 28 Volts, and is capable of conducting currents of up to 10 Amps. Afterward, the current falls to a lower level and it stops conducting.

When the device is fully off, it allows full voltage across the circuit. During a surge or spike, the device enters its conducting phase and clamps the voltage to the stated value. The device can handle a peak pulse power of up to 2455 Watts. If the surge lasts longer than its peak pulse power (20 µs) duration, it can survive without any damage.

The 5.0SMCJ24ATR is also able to sustain repetitive surge pulses, providing the circuit with protection against multiple transients. It is important to note, however, that this device should not be used to directly protect against electrostatic discharge events, and should not be the only component in an ESD protection circuit.

Conclusion

The 5.0SMCJ24ATR is a versatile, dependable, and cost-effective TVS diode, ideal for protecting sensitive electronic components from damaging voltage spikes and transients. With its quick response time, wide operating temperature range, and excellent peak pulse power capability, it is an excellent choice for applications across multiple industries, from automotive electronics to telecommunications equipment.
