ADB18PS February 1998 - Ed: 2 Peak pulse power dissipation 100 W (8/20µs) Stand-offvoltage : 18 V Maximum DC current : 0.5 A Clamping voltage : VCL < 50 V (8/20 µs)
FEATURES
Protectioncombined with rectification Highreliability conferedby monolithicconstruction Space saving Cost effective solution BENEFITS AUTOPROTECTED DIODE BRIDGE Application Specific Discretes A.S.D.TM Any electronic equipment needing a diode bridge and protection against transient overvoltage : Caller Id Handset MAIN APPLICATIONS 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.
