TVS Diode for 14V Rail Protection – 1500W Clamping
Its 1500W peak pulse power rating means it can absorb substantial surge energy without failing, making it a common choice for secondary protection on DC power inputs, I/O lines, and telecom interfaces in general-purpose equipment. The 14V reverse standoff voltage (VRWM) allows the device to sit across a 12V or 14V bus without conducting leakage current under normal operation. When a transient exceeds the 15.6V minimum breakdown voltage, the TVS clamps the surge to a maximum of 23.2V at the rated 64.7A peak pulse current, limiting the voltage stress on downstream components.
Package and Mounting – DO-214AB on Tape & Reel
The DO-214AB footprint is standard for 1500W TVS diodes, offering a low-inductance path and good thermal dissipation to the PCB copper plane.
This is a standard catalog part, available through authorized distribution channels. For BOM planning, the base product number SMCJ14 covers multiple voltage and package variants, so confirm the exact ordering code — including the /TR13 suffix for Tape & Reel — matches your assembly volume.
