This voltage stack defines the protection window: the rail stays below 170V during normal operation, and the device starts conducting between 189V and 275V to shunt transients. The 600W rating means it can absorb a single 10/1000µs surge up to that power level — enough for secondary protection on 170V DC buses, telecom lines, or industrial 120/240VAC rectified rails. ## Package and footprint — DO-214AA (SMB) DO-214AA (SMB) surface-mount package, a standard footprint for 600W-class TVS diodes. Verify pad geometry if replacing a different 600W TVS. ## Lifecycle status — active, no LTB risk For new designs or BOM replenishment, it remains a standard-sourced component through distribution.","metaTitle":"STMicroelectronics SMBJ170CA-TR TVS Diode","metaDescription":"SMBJ170CA-TR bidirectional TVS diode from STMicroelectronics, 600W peak pulse power, 170V standoff, clamp at 275V.

The SMBJ170CA-TR is bidirectional — both share the same footprint and voltage ratings, but the unidirectional variant has a single-direction clamp while the CA version clamps both polarities.
