Datasheet TLV431 (Diodes) - 2

TLV431 Typical Application Circuit
Secondary side 3.3 V regulated supply Optocoupler IF Primary side controller R3 R1 TLV431 R2 GND
Absolute Maximum Ratings
(@TA = +25°C, unless otherwise specified.)
Symbol Parameter Rating Unit
VKA Cathode Voltage 20 V IKA Continuous Cathode Current -20 to +20 mA IREF Reference Input Current Range -0.05 to +3 mA
ESD Susceptibility
(Note 4) HBM Human Body Model 4 kV MM Machine Model 400 V CDM Charged Device Model 1 kV Note: 4. Semiconductor devices are ESD sensitive and can be damaged by exposure to ESD events. Suitable ESD precautions should be taken when handling and transporting these devices.
Parameter Rating Unit
Operating Junction Temperature (Note 5) -40 to +150 °C Storage Temperature (Note 5) -65 to +150 °C Note: 5. Operation above the absolute maximum rating can cause device failure. Operation at the absolute maximum ratings, for extended periods, can reduce device reliability. Unless otherwise stated voltages specified are relative to the ANODE pin. These are stress ratings only. Operation outside the absolute maximum ratings can cause device failure.
Recommended Operating Conditions
(@TA = +25°C, unless otherwise specified.)
Symbol Parameter Min Max Units
VKA Cathode Voltage VREF 18 V IKA Cathode Current 0.1 15 mA TA Operating Ambient Temperature Range -40 +125 °C
