Additional Details

The SMBJ7.0A has a standoff voltage of 7.0V and a peak pulse power of 600W. It operates over a wide temperature range. The device is unidirectional, meaning it provides protection against positive transient voltages. Its glass-passivated junction ensures high reliability and stability under demanding operating conditions. The clamping voltage is a crucial parameter, defining the maximum voltage the TVS diode will allow to pass through to the protected circuit during a surge event.

Littelfuse is a recognized leader in circuit protection, and the SMBJ7.0A reflects their commitment to quality and performance. Its robust design and comprehensive protection features make it a popular choice for safeguarding sensitive electronics across a wide range of applications.
