Key Features

Shape flexibility: Round and square layouts optimized for uniform current density and maximum active area within press‑pack or stud outlines.

Base thickness options: Silicon base widths from 120 µm to 600 µm to match thermal impedance targets of your stack or module design.

Robust metallization: Ni/Ag frontside with optional Ti/Ni/Ag gate pad; full‑area Mo backside for reliable sinter or solder attach.

Avalanche capability: Dedicated diffusion profile provides controlled avalanche behavior for lightning‑surge or crowbar duty.

Ultra‑low leakage: Typical I_R ≤ 10 µA @ 125 °C for 2 kV parts; wafer‑level burn‑in available.
