The clamping voltage at 4.6A peak pulse current is 137V — that is the voltage the protected circuitry sees during a surge event. Surface-mount DO-214AA (SMB) package — the standard footprint for 600W-class TVS diodes. No official successor or second-source cross-reference is provided in the listing, so the SMBJ85CA-TR is the direct BOM fit for new and sustaining designs.","metaTitle":"SMBJ85CA-TR Bidirectional TVS Diode, 600W, DO-214AA SMB","metaDescription":"SMBJ85CA-TR bidirectional Zener TVS diode from STMicroelectronics TRANSIL™ series. 85V standoff, 600W peak pulse power, DO-214AA SMB package.
