NOTES:
(1) “ C “ Suffix indicates bi-directional
(2) ICTE-5 and 1N6373 are not available as bi-directional
(3) The minimum breakdown voltage as shown takes into consideration the ±1 Volt tolerance normally specified for power supply regulation on most integrated circuit
manufacturers data sheets. Please consult factory for devices that require reduced clamping voltages where tighter regulated power supply voltages are employed.
(4) Clamping Factor: 1.33 at full lo rated power; 1.20 at 50% rated power; Clamping Factor: the ratio of the actual Vc (Clamping Voltage) to the V
(BR)
(Breakdown Voltage)
as measured on a specific device.
