  1. Avalanche thyristor (series prefix “TL”)
  2. Design version
  3. Mean on‑state current ITAV, A
  4. Voltage code — e.g. 11 → 1100 V
  5. Group for critical rate of off‑state voltage (du/dt)crit (6 ≥ 500 V/µs, 7 ≥ 1000 V/µs)
  6. Turn‑off‑time group tq @ 50 V/µs (e.g. X2 ≤ 125 µs, A4 ≤ 100 µs, …, 0 = not limited)
