When a transient drives the line above 7.2 V minimum breakdown, the TVS turns on and clamps. The clamping ceiling of 11.2 V at peak pulse current is what the downstream IC sees during the event. For a 5 V rail, the 6.5 V standoff gives roughly 23 % margin above nominal; for a 12 V rail the margin is tighter, so the clamping ratio to the standoff voltage is the first thing to check against the downstream abs-max rating. ## SMC/DO-214AB package and surface-mount integration The SMC (DO-214AB) package is the industry-standard footprint for 1.5–3 kW TVS diodes on consumer and industrial boards. The cathode bar on the SMC marks the polarity — unidirectional operation only. The supplier device package field lists both SMC and DO-214AB, confirming the two naming conventions are interchangeable for this part. ## General purpose transient protection — where this class fits The 1.5SMCJ series is classified for general-purpose applications, not specifically automotive or industrial-high-reliability. Power line protection is listed as No: this part protects a signal or low-power rail, not a mains power bus.","metaTitle":"1.5SMCJ6.5A TVS Diode, 6.5V Standoff, 11.2V Clamping","metaDescription":"Diotec 1.5SMCJ6.5A unidirectional TVS diode, 6.5V standoff, 11.2V clamping @ 134A peak pulse, 1.5kW, DO-214AB SMC.

The 6.5 V version suits 5 V rails where the 23 % standoff margin above nominal is acceptable; the 7.0 V version is preferred when more margin above nominal is desired or when the 5 V rail tolerance is tighter.
