Diodes announced Miniature Surface Mount High Voltage Bridge Rectifiers for Power Adaptor Applications


Plano, Texas - Aug 10, 2018 - Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic, analog and mixed-signal semiconductor markets, today announced the introduction of a glass passivated miniature surface mount bridge rectifier series, designed in small form factor DBF and ABF packages. This bridge series enables 50% less utilization of PCB space, low profile design and provides low cost solutions for LED lighting and Power adaptors.

These bridge rectifiers have a high reverse breakdown voltage (VRRM ≥1000V) and a high forward current surge capability up to IFSM = 100A. RABF and RDBF bridges have tRR = 160ns ~ 500ns fast to ultrafast reverse recovery time help to improve efficiency. The glass passivated die construction provides robustness and high reliability.

The low typical VF  and IR characteristic help to improve efficiency, which is ideal for LED power supplies, PoE and adaptor applications.

Delivering superior performance, these devices are ideally suited for modern, high speed automated assembly processes.

Our DBF and ABF packages are green and RoHS-compliant. (See diodes.com for further details).

Advantage
■ Miniature Bridge Package and Low Profile Design (height<1.5mm)
    The small form factor of the DBF and ABF packages utilize 50% less PC boardspace than 4 individual SMA rectifier in a bridge configuration.
■ Low Reverse Leakage Current
    These devices have low reverse leakage current (IR<5uA @ VR=1,000V), whichhelps to improve the efficiency of the rectifier for reverse mode and switch-mode operation.
■ High Forward Surge Current Capability
    The clip die attach structure of the device enables it to withstand high surgecurrents (up to 100A), resulting in improved reliability and product lifetime.
■ Ultrafast to Fast Recovery Time Improves Power Efficiency
    RABF and RDBF bridges have 160ns ~ 500ns (tRR) fast to ultrafast reverserecovery time, which helps to improve switching and thermal efficiency.

Application
・SMPS for PC and servers
・Charger/adaptors
・LED lighting
・TV & monitor power supplies
・Power supplies
・Power over Ethernet (PoE)
