ADB18PS
AUTOPROTECTED DIODE BRIDGE
Application Specific Discretes A.S.D.TM
MAIN APPLICATIONS Any electronic equipment needing a diode bridge and protection against transient overvoltage : Caller Id Handset
TAB
DESCRIPTION The ADB18PS combines a diode bridge and a clamping protection function. Integrated monolithically within a SMD package, this device allows space saving and greater reliability. It provides both rectification and protection for low power equipment directly supplied by mains.
