That clamping ceiling is what downstream silicon sees — a 246 V clamp on a 150 V rail gives the downstream MOSFETs or ICs about 60 % headroom before their absolute maximum rating is reached. ## Single bidirectional channel, axial through-hole package A single bidirectional channel means one device protects against transients of either polarity — no need to series two unidirectional parts back-to-back. The DO-201AA (DO-27) axial package is a through-hole form factor with a 0.052-inch lead diameter, suited for point-to-point wiring or PCB mounting where the lead bend radius is controlled to avoid stress cracking the glass passivation. The wide junction temperature window means derating the peak pulse power at elevated ambient is necessary — the 1500 W rating is at 25 °C, and the derating curve in the datasheet governs the actual capability at 85 °C or 125 °C. ## General-purpose application, no power-line protection Classified for General Purpose applications, this TVS is not rated for power-line protection (the power line protection flag is No). It is intended for signal lines, DC buses, and low-impedance circuits where the 6.4 A peak pulse current at the clamping voltage is sufficient to shunt the transient energy without exceeding the device's thermal capacity. The 1.5KE series is a standard JEDEC-registered DO-201 footprint, so the 1.5KE180CA A0G is pin-compatible with other manufacturers' 1.5KE180CA devices from the same package family.","metaTitle":"1.5KE180CA A0G TVS Diode, 1500W, Bidirectional, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE180CA A0G bidirectional TVS diode, 1500W peak pulse power, 154V standoff, DO-201 axial.
