1500W axial TVS for DC rail clamping
The 1.5KE10A B0G: The reverse standoff voltage of 8.55V means the rail it protects should operate at or below that level; the device remains transparent until a transient drives it into breakdown at 9.5V minimum, clamping at 14.5V maximum while shunting up to 108A. This window — 8.55V standoff, 9.5V breakdown, 14.5V clamp — is the core selection parameter for a given DC bus voltage.
DO-201 axial — pulse energy and board integration
Housed in a DO-201AA (DO-27) axial-leaded package, this TVS is a through-hole part — the leaded form factor handles the thermal and mechanical stress of repeated high-energy pulses better than a surface-mount equivalent of the same power class. The 1500W rating is tested with a 10/1000µs exponential waveform; for shorter pulses (e.g. 8/20µs per IEC 61000-4-5), the peak power capability is higher, but the datasheet's derating curve must be consulted for the actual pulse width. The wide range means the clamping voltage and leakage current shift with temperature — at 175°C, leakage rises significantly, so the rail impedance and load current budget should account for this at the high end.
The base product number 1.5KE10 covers the 10V standoff family; the A suffix denotes a 5% tolerance on breakdown voltage. The B0G suffix is a packaging and environmental code (bulk, RoHS-compliant).
