SMBJ400C

TVS (Transient Voltage Suppression) diodes, also known as Transient Voltage Suppressors (TVS), are designed to prevent high voltage spikes from damaging electronic components such as microprocessors, memories, and printed circuit boards. The SMBJ400C is a series of unidirectional devices designed to protect against such transients.

The SMBJ400C is designed for deployment in applications where over-voltage transients have the potential to cause damage or disruption. The device works by responding quickly to an instantaneous increase in voltage, and limiting the transient voltage to a safe level. It can handle up to 400W peak power, has a response time of less than 1ns and an unclamped operating voltage of 32V.

The SMBJ400C is commonly used to protect against over-voltage transients in industrial control and automotive systems, pro audio and other professional audio applications, power systems, telecommunication equipment, and other electronic devices. These devices are available in 3-pin and 4-pin packages, and are widely used in medical and health care equipment, consumer electronics, automotive industry, and other applications where over-voltage protection is critical.

The SMBJ400C works by sensing an over-voltage condition, which triggers the device to clamp the voltage to a safe level. It operates by rapidly charging the junction capacitance with a large peak current at the onset of the transient event, which reduces the forward voltage and current from the power source. This helps to protect the protected device from the transient spike. It also helps to prevent the associated static or dynamic current that could otherwise be generated.

The SMBJ400C also features an enhanced peak power rating, allowing for higher peak pulse currents than traditional TVS diode devices. This increase in peak power helps to increase the protection for the sides of the device that experience the highest peak currents.

The SMBJ400C is a reliable device designed for over-voltage protection of sensitive electronics. The device is fast in response time and compact in size, making it a perfect solution for applications where space is limited. The SMBJ400C provides superior protection against high voltage spikes and over-voltage conditions, protecting electronics and systems from damage or disruption.
