Product details

1500W peak pulse in a DO-201 axial package

The 1.5KE300A B0G: The 256V reverse standoff voltage (working voltage) and 285V minimum breakdown voltage mean it starts clamping just above the normal rail voltage, protecting downstream circuits from transients up to 414V clamping at 3.8A peak pulse current. The DO-201AA (DO-27) axial-lead package suits through-hole assembly on power supply boards, telecom line cards, or industrial control PCBs where a single TVS absorbs high-energy surges without needing a surface-mount footprint.

Active lifecycle, no line-item risk

Taiwan Semiconductor lists the 1.5KE300A B0G as Active. The bulk packaging is standard for axial diodes; no minimum order quantity surprises at the distributor desk.
