FEATURES AND BENEFITS
ABSOLUTE RATINGS (limiting values, per diode)
MAJOR PRODUCT CHARACTERISTICS
TM: ISOTOP is a registered trademark of STMicroelectronics.1/7
Pulse test : * tp = 380 μs, δ < 2%
** tp = 5 ms, δ < 2%
STATIC ELECTRICAL CHARACTERISTICS (per diode)When the diodes 1 and 2 are used simultaneously : Δ Tj(diode 1) = P(diode) x Rth(j-c) (Per diode) + P(diode 2) x Rth(c)
THERMAL RESISTANCESTo evaluate the conduction losses use the following equation:
P = 1.47 x IF(AV) + 0.005 IF2 (RMS)
