Low-capacitance steering diodes

3 February 2010 Power Electronics / Power Management

Diotec has introduced the MYS series of miniature bridge rectifiers, ideally suited as protective elements for high-speed telecommunication systems. The typical junction capacitance of these devices is 3 pF at 4 V/1 MHz.

The MYS series’ capacitance of only 6 pF at 0 V is considered an advantage over TVS diodes and thyristors, whose much higher capacitances disturb the bandwidth of high-speed telecommunication systems. This makes these new devices highly suitable as steering diodes for VDSL, ADSL and Ethernet systems. The MYS125, having 250 V of maximum reverse voltage, would suit most telecom systems; higher voltages are also available.

The bridge has a solid soldered construction for high surge capability and can easily handle surges related to the capacitive discharge of the isolation transformer and secondary lightning surges. The devices have 1,27 mm pitch and their height of 1,9 mm means that they can be mounted on the wave soldering side of densely populated telecom boards. The absence of wire bonds reduces inductance.
