SMBJ250E3/TR13

TVS - Diodes

TVS (Transient Voltage Suppressors) diodes are components used to protect a system circuit from transient overvoltage damage. SMBJ250E3/TR13 is a low power TVS diode that can be used to protect against overvoltage spikes and transient events. It has a fast response time of 8 nanoseconds. This diode is available in two breakdown voltages: 14V and 20V. The SMBJ250E3/TR13 provides up to 3A of dynamic protection.

Application Field

SMBJ250E3/TR13 TVS diodes are designed for ESD (electro static discharge) and other overvoltage protection applications. They are mainly used in automotive, aviation, industrial, consumer electronics, and other industries to protect electrical and electronic circuits from damage due to electrical transients. The SMBJ250E3/TR13 can be used to protect a wide variety of circuits, including DC-DC converters, MOSFETs, IGBTs, FETs, and logic circuits. It is also used to protect signal lines, such as USB and Ethernet cables.

Working Principle

The working principle of the SMBJ250E3/TR13 is based on the ability of a diode to conduct current in one direction while blocking current in the opposite direction. The SMBJ250E3/TR13\'s breakdown voltage is determined by the PN junction formed between the P-type and N-type semiconductor layers. When an overvoltage event occurs, the current will flow through the PN junction and the diode will conduct, providing protection to the circuit. The diode will return to its off-state and the voltage will return to normal once the event is over.

Conclusion

SMBJ250E3/TR13 TVS diodes are a cost-effective way to protect sensitive circuits and equipment against electrical transients. These devices are designed to respond quickly and effectively to overvoltage events, ensuring the safety and reliability of the system. The SMBJ250E3/TR13 is widely used in many industries and applications due to its low cost and fast response time.
