S6J3310/20/30/40 Series
Reverse polarity condition specification:
U_reverse = max -28 V
T_reverse = max 4 h
Current and Power Dissipation
U_reverse = -28 V
R_serial = 22 k
=> I_pin = 1.3 mA
U_out = -0.7 V (current drawn mainly over clamping diodes)
=> I_total = 50 pins x 1.3 mA = 65 mA
=> P_total = 50 pins x (1.3 mA x 0.7 V) = 46 mW
I_total and P_total are within allowed limits of extended specification.
• The - B signal should always be applied by connecting a limiting resistor between the - B signal and the microcontroller.
• The value of the limiting resistor should be set so that the current input to the microcontroller pin does not exceed rated
values at any time regardless of instantaneously or constantly when the - B signal is input.
• Do not leave - B input pins open.
Example of a recommended circuit
WARNING:
−
Semiconductor devices may be permanently damaged by application of stress (including, without limitation, voltage, current
or temperature) in excess of absolute maximum ratings. Do not exceed any of these ratings.
