DSR8F600 Rectifier
600V Hyper-Fast Rectifier Improves Power Efficiency
for PFC and CCM Applications
Diodes Incorporated announces the
introduction of the new DSR8F600
which is the initial release of a series
of high voltage and hyper-fast
rectifiers. The new rectifier is housed
in the industry standard molded plastic
TO220AC package.
The DSR8F600 features high reverse
breakdown voltage (VRRM e600V),
maximum average rectified output
current (IO=8A), low forward voltage
drop (VF_TYP=1.95V @ +25ºC), hyperfast reverse recovery time
(tRR_MAX=20ns @ +25ºC), and low
reverse recovery current (IRM_TYP=3.9A
@ +25ºC). These unique features
reduce conduction losses and alleviate
stress in MOSFETs.
The DSR8F600 has been designed
specifically for use as a boost diode in
Power Factor Correction (PFC) and
Continuous Conduction Mode (CCM)
applications. In addition, the very fast
soft recovery characteristic of the
rectifier minimizes noise generation
and ensures ringing and EMI are
reduced.
The targeted end markets for the
DSR8F600 are high output SwitchedMode Power Supply (SMPS), servers
and telecom equipment, and flat panel
TVs.
Delivering superior performance, the
DSR8F600 is ideally suited for today’s
high-speed fully automated assembly
processes.
The TO220AC case is fully green and
RoHS-compliant. (See diodes.com for
further details).
The Diodes’ Advantage
 Hyper-Fast Reverse Recovery Time
The DSR8F600 has hyper-fast reverse recovery time (tRR_MAX=20ns @ +25ºC)
which allows for faster switching speed and reduces power losses.
 Low Forward Voltage Drop
With low forward voltage drop (VF_TYP=1.95V @ +25ºC), the DSR8F600 reduces
boost diode conduction losses.
 Low Reverse Recovery Current
The DSR8F600 has low reverse recovery current (IRM_TYP=3.9A @ +25ºC) which
minimizes the boost diode recovery losses and improves the power efficiency.
 Very Fast Soft Recovery Capability
The very fast soft recovery characteristic of the DSR8F600 ensures ringing and
EMI are reduced. The boost diode is ideally suited for use in hard switching and
CCM power circuits.
