1.5KE33-B

TVSs or transient voltage suppressors are diodes that have a very high peak pulse power rating to protect sensitive electronic components from transient overvoltage. The 1.5KE33-B is one such example. It has a maximum peak pulse power of 600 Watts and an operating junction temperature of 175°C.

The 1.5KE33-B is designed for overvoltage protection of datasheet applications, circuits and systems. It provides effective protection against surges and other transient voltages, including electro-static discharges (ESD), spike, surge or inductive transients. It offers a generous working voltage range of 10V to 32V and a breakdown voltage of 33V.

The 1.5KE33-B has a forward voltage drop of 5V and a reverse current of 500µA at 33V. It is also designed to withstand a repetitive peak pulse current of 2.5A without any damage. The device has a low capacitance of 0.2pf, making it an ideal choice for low-voltage data lines such as RJ-11, RJ-45, USB, IEEE1394 and HDMI.

The main working principle of the 1.5KE33-B is based on the zener diode’s ability to shunt current away from a protected circuit. When a transient voltage exceeds the breakdown voltage (Vbr), the zener diode turns on and diverts the current away from the protected circuit. The 1.5KE33-B also has a Fused Silicone Axial Lead Mounted Thyristor (FSLMT) that senses the incoming voltage surge and rapidly switches off, thereby protecting the downstream circuit. This feature ensures that the 1.5KE33-B can handle transient surges of up to 600 Watts.

The 1.5KE33-B is an excellent choice for overvoltage protection applications due to its robust construction and high pulse power rating. It can be used in a wide range of consumer electronics, automotive, industrial, telecom and computer applications. It offers superior protection against ESD and other transient voltages, making it suitable for a variety of systems and applications.

In summary, the 1.5KE33-B is a highly reliable transient voltage suppressor designed for overvoltage protection applications. It offers a high peak pulse power rating of 600 Watts, low capacitance and a robust construction. It is suitable for a variety of applications and systems and offers superior protection against ESD, spike, surge and inductive transients.
