The MMBD5004BRM quad switching diode array from Diodes has a breakdown-voltage rating of 400V and is designed to withstand worst-case line transients in DAA-modem tip-and-ring telephone line interfacing and general off-line rectification applications. The diode array's combination of a 50ns switching speed with a junction capacitance of 0.7pF at a reverse voltage of 0V and a 1MHz frequency, makes it suitable for preserving high-speed signal integrity, while its current rating of 225mA continuous and 625mA peak provides for a healthy margin for DAA-modem needs. The diode array comes in a space-saving SOT26 package. It houses two separate pairs of series-connected diodes that act as a full-wave bridge rectifier.
