HV Diode Array Withstands Phone-Line Transients

Specifying a breakdown voltage of 400V, the MMBD5004BRM quad switching diode array withstands worst-case transients in DAA modem tip-and-ring telephone line interfacing and general off-line rectification apps. With a switching speed of 50 ns and a junction capacitance of 0.7 pF at VR=0V and f=1 MHz, the device preserves high-speed signal integrity. Additionally, a current rating of 225 mA continuous and 625 mA peak provides a safe margin for DAA modem needs. Hosting two pairs of series connected diodes in a compact SOT26, price for the MMBD5004BRM is $0.08 each/10,000. DIODES INC., Westlake Village, CA. (805) 446-4800.
