The 80.3V clamping maximum at 7.5A peak pulse sets the voltage the downstream circuitry must survive during a 10/1000 µs surge event. The bidirectional configuration protects both polarities with a single device, saving board space on AC-coupled or bipolar lines. ## Package and temperature range for the board The base product number SMBJ45 is shared across the family, so confirm the suffix for the bidirectional C-suffix and lead-free finish.","metaTitle":"SMBJ45CE3/TR13 – Microchip 600W Bidirectional TVS","metaDescription":"SMBJ45CE3/TR13 Zener TVS diode, 45V reverse standoff, 80.3V clamp, 600W peak pulse, bidirectional, DO-214AA.
