Additional Details:

The TPSMB13A-801E3/52T has a stand-off voltage of 13V. The breakdown voltage is typically 14.4V and a maximum clamping voltage around 21.5V at a specified test current. It features a peak pulse power dissipation of 600W for a 10/1000 µs waveform. It is designed to operate over a temperature range typically from -65°C to +150°C. This TVS diode is RoHS compliant. The SMB package dimensions should be verified in the datasheet to ensure proper PCB layout and soldering procedures are followed. The unidirectional configuration means it provides protection against positive voltage transients; it is not suitable for applications requiring bidirectional protection without additional circuitry. Proper grounding is crucial for effective TVS diode operation.
