The 21.7A peak pulse current (10/1000µs) sets the surge-handling ceiling; for longer-duration transients, derate per the pulse-width curve in the datasheet. ## Sourcing and lifecycle posture No official pin-compatible successor or second-source cross-reference is published by Bourns for this order code. The 1.5SMBJ series includes multiple voltage variants in the same DO-214AA footprint; the 43V standoff version is the one that matches a 43V rail.","metaTitle":"Bourns 1.5SMBJ43CA TVS Diode, 43V Standoff, 1.5kW, AEC-Q101","metaDescription":"Bourns 1.5SMBJ43CA bidirectional TVS diode, 43V reverse standoff, 1.5kW peak pulse, AEC-Q101 qualified.
