The reverse standoff voltage of 170V is the maximum continuous DC voltage the TVS can withstand without significant leakage — a 170V bus or a 170V telecom line sits safely below the avalanche knee. The clamping voltage of 275V at 1.4A peak pulse current defines the protection ceiling: any transient that drives the line above 275V is clipped. The 400W peak pulse power (calculated as clamp voltage × peak current) confirms the device can absorb a single 10/1000µs surge up to that energy without failing short. ## DO-214AC SMA footprint and thermal range Housed in the DO-214AC (SMA) package, the SMAJ170A-13 is a surface-mount device with a standard JEDEC footprint.","metaTitle":"SMAJ170A-13 Diodes Inc TVS, 170V Standoff, 400W, DO-214AC","metaDescription":"SMAJ170A-13 Zener TVS diode, 170V reverse standoff, 275V clamp, 400W peak pulse power.
