The SMBJ20CA-13 from Diodes Incorporated is a robust transient voltage suppressor (TVS) diode, designed to protect sensitive electronic equipment from voltage spikes and transients induced by lightning and other transient voltage events. This TVS diode is a popular choice for safeguarding voltage-sensitive components which can be affected by sudden voltage variations, making it an essential component in a wide range of applications, including consumer electronics, automotive systems, and industrial equipment.

Key Features

• Bi-directional Protection: The SMBJ20CA-13 is a bi-directional TVS diode, which means it can provide protection for electronic circuits from voltage transients in both forward and reverse directions.
• Stand-Off Voltage: This device has a stand-off voltage of 20V, which is the maximum voltage that can be applied over the diode without causing it to conduct significant current.
• Peak Pulse Power: It features a peak pulse power dissipation of 600W for a 10/1000μs waveform, ensuring reliable protection against high energy transients.
• Fast Response Time: With a response time typically less than 1 picosecond from 0V to BV min, the SMBJ20CA-13 provides prompt protection for sensitive circuits.
• Operating Temperature Range: The device can operate effectively over a wide temperature range from -55°C to +150°C, suitable for various challenging environments.
• Package: It comes in the surface-mount SMB (DO-214AA) package, which is ideal for automated assembly processes and helps in saving valuable board space.
