The Automotive grade designation means the part is screened for the -55°C to 150°C junction temperature range and meets the reliability requirements for under-hood and chassis-domain electronic modules. Power line protection is not supported — this is a signal or low-power bus protection device. ## DO-214AA SMB surface-mount package Housed in the DO-214AA (SMB) package, a standard JEDEC outline for 1.5 kW TVS diodes. The surface-mount footprint is compatible with reflow soldering profiles used in automated assembly. Supplied in Tape & Reel packaging for pick-and-place.","metaTitle":"Bourns 1.5SMBJ43A TVS Diode, 1.5 kW, 43 V Standoff, AEC-Q101","metaDescription":"Bourns 1.5SMBJ43A Zener TVS diode, 1500W peak pulse power, 43V reverse standoff, AEC-Q101 automotive grade.
