Small Signal Diodes

Absolute Maximum Ratings* TA = 25°C unless otherwise noted

Symbol	Parameter	Value	Units
VRRM	Maximum Repetitive Reverse Voltage	200	V
IF(AV)	Average Rectified Forward Current	200	mA
IFSM	Non-repetitive Peak Forward Surge Current	1.0	A
	Pulse Width = 1.0 second
	Pulse Width = 1.0 microsecond	2.0	A
Tstg	Storage Temperature Range	-55 to +150	° C
TJ	Operating Junction Temperature	150	° C

*These ratings are limiting values above which the serviceability of any semiconductor device may be impaired.

NOTES:

1)These ratings are based on a maximum junction temperature of 150 degrees C.

2)These are steady state limits. The factory should be consulted on applications involving pulsed or low duty cycle operations
