1500 W bidirectional TVS in the 1.5KE series
The 1.5KE82CA R0G: The 70.1 V reverse standoff means the diode stays in a high-impedance state below that DC bus or signal voltage, drawing negligible leakage. Once a transient pushes the line above 77.9 V, the device breaks down and shunts the surge to ground, holding the protected node to 113 V or less.
Package and board-fit for through-hole assembly
Housed in a DO-201AA (DO-27) axial-lead package with a DO-201 supplier device code, the 1.5KE82CA R0G is a through-hole part intended for wave-solder or hand-solder assembly. The axial leads allow it to be mounted standing upright or laid flat against the board, depending on the available clearance and thermal management needs. The 1500 W peak pulse rating is derated linearly above 25°C; at 175°C the device still handles roughly 300 W, which is adequate for most secondary surge protection stages.
Active production and sourcing posture
Taiwan Semiconductor lists the 1.5KE82CA R0G as an active product. The R0G suffix denotes Tape & Reel packaging, which is the standard reel format for axial-lead diodes — suitable for automated insertion but also available in cut-tape quantities for prototype or repair runs. The key parametric match is the 70.1 V standoff, 77.9 V breakdown, and 113 V clamp — any supplier's part meeting those figures is a direct drop-in for the BOM line.
