DALLAS, USA: Diodes Inc., a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete and analog semiconductor markets, has introduced a miniature quad switching diode array, the MMBD5004BRM, which was designed for bridge implementation and ideally suited for Modem (Modulator-demodulator) tip/ring interface and general light duty offline rectification applications.
Designed for bridge implementation, this device eases interface to telephone tip/ring applications and complies with the FCC (telco) polarity requirements. The device’s high-voltage rating (400V) provides adequate margin over the maximum ringing voltage specified by the FCC and provides excellent tolerance to line transients.
The MMBD5004BRM’s miniature form factor SOT26 packaging helps enable cost and space savings in DSL, analog and DAA (Direct Access Arrangement) Modems, as well as answering machines and caller identification systems.
The diode array’s combination of fast switching speed and low junction capacitance makes it ideal for preserving high-speed signal integrity while its high current rating of 225mA continuous and 625mA peak provides a healthy margin for general light duty rectification applications.
A smaller quad diode implementation than many existing mini-bridge solutions, the MMBD5004BRM comes in a space-saving SOT26 package. Housing two separate pairs of series connected diodes for linking as a full-wave bridge rectifier, the diode array will suit applications where PCB size and cost are critical.
