The HSP061-4M10 is a versatile ESD protection device suitable for a wide range of applications. It is often used in automotive, consumer electronics, industrial, and medical applications where transient voltage protection is required. In automotive applications, it is used to protect sensors, audio systems, and telematics systems. In consumer electronics, it is used to protect HDMI, USB, and other audio and video ports from transient voltage surges. In industrial applications, it is used to protect PLCs, motors, and other industrial equipment. In medical applications, it is used to protect medical devices from power surges. The HSP061-4M10 can also be used in other motor control, telecommunications, and data communication applications.

Working Principle

The HSP061-4M10 is a unidirectional TVS diode that works by clamping the voltage of the protected circuit. It operates by using a FET switch and a resistor. When the voltage of the protected circuit rises above the breakdown voltage, the diode conducts current, pulling the FET’s gate voltage to ground. This causes the FET to turn on, and the resistor supplies current to the gate, causing it to remain on. This keeps the voltage of the protected circuit clamped at a safe level. The active clamp allows the diode to respond quickly to transient voltage spikes, protecting the circuit from damage.

Conclusion

The HSP061-4M10 is a versatile ESD protection device suitable for a wide range of automotive, consumer electronics, industrial, and medical applications. Its advanced ESD protection platform offers greater dynamic range and faster response times compared to typical TVS diodes. Its active clamp allows it to respond quickly to transient voltage spikes, protecting the circuit from damage.
