When a surge exceeds the 285V minimum breakdown voltage, the device avalanches and clamps the spike to 414V maximum while shunting 3.8A of peak pulse current in the standard 10/1000µs waveform. The DO-201AA axial lead package solders into a through-hole board; the leads carry the surge current into the junction without the trace-width bottleneck you get with an SMD package on a two-layer board. The 175°C upper limit means the junction can absorb the self-heating from a pulse without derating the peak power at elevated ambient, as long as the average power stays within the thermal resistance of the axial lead mounting. The bidirectional configuration clamps both polarities with a single device, which is the right call for AC-coupled signal lines or DC rails where the transient can ring positive and negative. ## Active lifecycle and procurement reality This is a standard catalog TVS diode in the 1.5KE family, a mature product line that has been in continuous production for years. The DO-201 package is a common through-hole footprint, so the part mates with standard 0.100-inch pitch board layouts without a pad pattern change.","metaTitle":"1.5KE300CA B0G TVS Diode, 1500W, 256V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE300CA B0G bidirectional Zener TVS, 1500W peak pulse, 256V standoff, 414V clamp.

If your downstream components have a 500V breakdown rating, you have 86V of margin. If they are rated 400V, the clamp sits at the edge — you need to verify the transient energy does not push the diode into a higher clamping region or add series resistance to limit current."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/taiwan-semiconductor-corporation/1.5KE300CA-B0G","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/taiwan-semiconductor-corporation/1.5KE300CA-B0G when reusing this data.
