Product details

1500W bidirectional TVS for telecom line protection

The 1.5SMB24CA: The single bidirectional channel means one device clamps both positive and negative surges, saving board space and bill-of-materials count compared to back-to-back unidirectional diodes. The breakdown voltage range starts at 22.8V minimum, giving margin above the 20.5V standoff before the device begins conducting.

Package and rework — DO-214AA (SMB) surface mount

The package comes in Tape & Reel (TR) format, suited for automated pick-and-place assembly. Operating temperature spans -65°C to 150°C junction, covering telecom outdoor cabinets and industrial enclosures without derating concerns.
