The SMBJ6.5CA R4G is an unidirectional Transient Voltage Suppressor (TVS) diode. It is a low-power, surface-mount component manufactured by Taiwan Semiconductor which meets the RoHS standard. The diode is packaged in a DO-214AA SMB package, which features a two-lead, axial outlet configuration, meaning the two leads of the device protrude in parallel from the side of the package. The SMBJ6.5CA R4G has a peak pulse power rating of 600 W at a 6.5 V reverse voltage (VRWM). It has a peak pulse current rating of 1 A and a clamping voltage of 15 V. The device is typically used as protection in applications such as telecommunications hardware, computers, consumer electronics, and other telecommunications equipment.
