For a 90V rail, this part stays off until a transient pushes the line above 100V — the breakdown knee. The 146V clamp voltage is the worst-case peak the protected circuitry sees during a surge event. For a given transient energy, the clamp voltage determines the peak current — 4.1A at the 146V clamp. If your application sees repetitive surges or longer pulse widths, derate accordingly. The unidirectional configuration means one channel per device, with the cathode band marking the protected line side.","metaTitle":"Diodes Inc SMBJ90A-13 TVS Diode, 90V Standoff, 600W","metaDescription":"SMBJ90A-13 TVS diode from Diodes Inc, 90V reverse standoff, 146V clamp, 600W peak pulse power in DO-214AA SMB.
