Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
1. I_reg(SS) steady state is the voltage (Vak) applied for a time duration ≥ 300 sec, using 900 mm² DENKA K1, 1.5 mm Al, 2kV Thermally
conductive dielectric, 2 oz. Cu (or equivalent), in still air.
2. V_overhead = V_in − V_LEDs. V_overhead is typical value for 70% I_reg(SS).
3. I_reg(P) non−repetitive pulse test. Pulse width t ≤ 360 msec.
