The bidirectional configuration (one channel) protects signal or power pairs where the transient can swing either polarity — common on AC-coupled data lines, 90 VDC bus rails, or telecom interfaces that see both positive and negative surges. The 600 W rating at the 10/1000 µs pulse defines the energy it absorbs in a single event; for shorter pulses the peak power capability is higher, but the 146 V clamp is the hard ceiling the downstream circuitry must survive. For a 90 V rail in a motor-drive or power-supply output stage, the 4.1 A peak pulse current at the clamp voltage gives a rough surge-energy budget of about 600 mJ per event — enough for most IEC 61000-4-5 level 2 or 3 transients when the source impedance is 2 Ω or higher. ## Active production and sourcing posture The base product number SMBJ90 identifies the voltage family; the CA suffix marks the bidirectional polarity, and the -13 tape-and-reel suffix indicates the standard 13-inch reel packaging for automated pick-and-place.","metaTitle":"SMBJ90CA-13 Diodes Inc TVS, 600W, 90V Bidirectional","metaDescription":"SMBJ90CA-13 bidirectional TVS diode, 600W peak pulse, 90V standoff, 146V clamp.
