SPHV24-01ETG-C (Transient Voltage Suppressor, TVS) are designed to provide surge protection in telecommunication and computer peripherals, consumer electronics, entertainment systems, and automotive applications. The device is designed to protect these applications from the voltage surges produced by lightning, inductive load switching, and voltage transients from the power line. SPHV24-01ETG-C is a three-pin diode, comprising an electrode, a body diode and a third lead connected to the body diode. The device provides protection against overvoltage transients by allowing current to pass from anode to cathode, or vice versa, when triggered. Since the SPHV24-01ETG-C is normally biased in the reverse direction, the flow of current is limited to the maximum rated breakdown voltage of the device.

The working principle of the SPHV24-01ETG-C device is based on the avalanche breakdown of the junction between an anode and a cathode. When a voltage transient exceeding the rated breakdown voltage (VBD) of the device is applied across the anode and cathode, the diode junction “avalanches”, resulting in a significant increase in electric current flow in the device. The avalanche current causes a rapid increase in temperature and an arc spark in the diode junction, resulting in a significant increase in the device’s voltage drop. The increase in voltage drop can be measured with a simple 50 ohm resistor connected between the anode and cathode, while the increase in current is measurable with a current probe connected across the diode.

Once the device has been triggered due to a voltage transient, the device must be reset before it can be used again. This process involves heating the diode junction to a temperature higher than the breakdown voltage, and allowing the device to cool. The reset temperature of the SPHV24-01ETG-C device is typically about 130°C. It is important to note that the device must be properly cooled before reset, otherwise the reset process may be incomplete. This can result in partial failure or permanent damage to the TVS.

The SPHV24-01ETG-C is an economical and reliable solution for protecting against transient voltage surges, and is well suited for a variety of applications in consumer electronics, telecom, automotive, and industrial sectors. The device is available in a variety of packages, including SMT, DIP, and TO-220. The device has a wide operating temperature range of -65°C to +125°C and is available in a variety of voltages and current ratings. This makes the SPHV24-01ETG-C an ideal choice for protecting sensitive electronic components against voltage transients in a variety of applications.
