SMBJ120A Description

Short technical summary and product information.

The GOODWORK SMBJ120A is a unidirectional Transient Voltage Suppressor (TVS) diode, categorized under ESD Protection Diodes. This component is designed to protect sensitive electronic circuits from transient overvoltage events, particularly those caused by electrostatic discharge (ESD).

Key electrical characteristics include a reverse stand-off voltage of 120V, a minimum breakdown voltage of 133V, and a maximum breakdown voltage of 153V. The maximum clamping voltage is rated at 193V, with a peak pulse current handling capability of 3.1A at a 10/1000µS waveform. The reverse leakage current is a low 5µA.

This TVS diode is housed in an SMB (DO-214AA) package, suitable for surface mount applications. Its unidirectional polarity makes it ideal for applications requiring protection on a single line.

X-On Electronics recognizes this part as a product manufactured by GOODWORK, offering cost-effective solutions with global delivery.
