It also features an operating temperature range of -65°C to +150°C, and is compliant with RoHS environmental directives.

Application Field

The IP4233CZ6,125 TVS diode is suited for a wide range of applications including digital and analog communications over long distances, digital signal processing, consumer electronics, automotive electronics, and industrial control systems. It is ideal for use on inputs or outputs of microcontrollers, logic gates, operational amplifiers, and communication lines against surges caused by lighting, EFT, and other transients.

Working Principle

TVS diodes are made up of bidirectional semiconductor devices that protect sensitive electronic components by forming a low-impedance path and conducting any surging or overvoltage currents safely away from the protected circuit. When the voltage on the protected line exceeds the protection threshold, the device will conduct the excess current away from the sensitive element while simultaneously clamping the voltage to a safe level.

The IP4233CZ6,125 diode is designed to protect circuits and devices from both positive and negative transients. It uses a PN junction which acts like a regular diode, allowing current to flow in one direction only. When the transient voltage exceeds the breakdown voltage, a low impedance path is created, allowing current to flow in either direction. This provides fast and effective protection against power surges, EFT, and other voltage overload. The PN junction also passes a small amount of leakage current when the input voltage is zero, thus preventing false triggering.

Conclusion

The IP4233CZ6,125 is a TVS diode designed to protect circuits and devices from overpowering and damaging conditions such as electrical overvoltage caused by cable transients or other events. It features a low 5Ω typical clamping voltage, and a high surge capability of 1500W for 8/20μS waveforms, as rated under IEC 61000-4-5. With its fast response time and low leakage current, it is well suited for use in digital and analog communications, digital signal processing, consumer electronics, automotive electronics, and industrial control systems.
