Specification Brand : Tyenaza BulletPoint : - Panel mount : Screw-on mounting front side - 3 Functions : Appliance Inlet Protection class I , Line Switch 1-pole , Line-filter in standard version - Quick connect terminals 6.3 x 0.8 mm BulletPoint1 : The ULN2803A device is a 50 V, 500 mA Darlington transistor array. BulletPoint2 : The device consists of eight NPN Darlington pairs, which have a high voltage output and a common cathode clamp diode for switching inductive loads. BulletPoint3 : The collector current rating of each Darlington pair is 500 mA. Darlington pairs can be connected in parallel to increase current capacity. BulletPoint4 : Applications include relay drivers, hammer drivers, lamps drivers, display drivers (LED and gas discharge), line drivers and logic buffers. BulletPoint5 : Each Darlington pair of ULN2803A devices has a 2.7kΩ series base and can work directly with TTL or 5V CMOS devices IncludedComponents : 1 ItemName : Tyenaza 2Pcs Power Supply Module, ULN2803A Module Darlington Tube High Current Voltage Driver Electric Component, Voltage Driver Power Supply Module ItemPackageDimensions_Height : 2 centimeters ItemPackageDimensions_Length : 8 centimeters ItemPackageDimensions_Width : 6 centimeters ItemTypeKeyword : power-entry-modules Manufacturer : Tyenaza ModelNumber : Tyenazawum0osty13 NumberOfItems : 1 PartNumber : Tyenazawum0osty13 ProductDescription : Item Type: ULN2803A moduleCollector-Emitter Voltage: DC50V Input Voltage: DC30V Collector Peak Current: 500mA Output Clamp Current: 500mA Junction Temperature: -65--150℃ Storage Temperature: -65--150℃
