Surge Protection Diodes (SPDs) are a class of Transient Voltage Suppression (TVS) diodes specially engineered and designed to protect electrical circuits from transient overvoltage in the form of lightning or static electricity. The SMB10J28-E3/52 is one such product designed for the task of protecting such voltage spikes from destroying an electrical circuit.

The SMB10J28-E3/52 are particularly known for their ability to suppress transients up to 32V common-mode and overvoltage surges, while clamping the voltage at 15.3V. Its very fast condition response time- less than 100ns- allows the device to protect your circuit from lightning strikes of up to 8.3x50μs waveform.

Applications for this device can range from cellular phone chargers to power supplies for servers. It is capable of protecting any load with its peak current capability of 700A. This device is especially beneficial in industrial environments, where overvoltage surges are common due to the high concentration of electrical machinery found in any industrial setting. The SMB10J28-E3/52 can also be found in audio/video systems as a protection device against lightning strikes and any other overvoltage surge.

The SMB10J28-E3/52 is designed to work by clamping the surge and diverting it away from sensitive components. In the event of a voltage spike, the device will act as a high impedance path to bypass the surge around the protected component, thereby effectively isolating the surge and preventing any damage.

It is important to note that this device is optimized to protect against common-mode and transverse-mode surges. Common-mode surges are typically caused by external sources such as lightning while transverse-mode surges tend to originate from internal sources such as inductive loads. The device also features an integrated Thermal Shutdown (TSD) function which will automatically shut down the device in case the junction temperature rises too high.

In conclusion, the SMB10J28-E3/52 is a highly robust protection device designed to protect electrical circuits from damaging overvoltage surges. It is capable of providing protection from both external and internal sources and comes with an invaluable integrated thermal protection feature. It is widely used in numerous applications, from cellular phone chargers to audio/video systems and is especially beneficial in industrial settings, where surges are more common.
