RatingSymbolValueUnit
Peak pulse power dissipation (1) , TJ initial = Ta W
Power dissipation on infinite heat sink , Ta = 75ºCW
Non repetitive surge peak forward current
for unidirectional type , tp = 10 ms ,TJ initial = Ta
Maximum lead temperature for soldering during 10s
at 5mm from case
Thermal resistance junction to lead ºC/W
Thermal resistance junction to ambient, L = 10mmºC/W
Operating and storage temperature range TJ, TSTG - 65 to + 175 °C
Note:
(1) For surge greater than the maximum values, the diode will fail in short-circuit.

Notes:
(1) Pulse test : tp < 50 ms.
(2) Δ VBR = αT * (Ta - 25) * VBR (25ºC)
(3) VR = 0V, f = 1MHz. For Bidirectional types, capacitance value is divided by 2.
