Features and Benefits
Patented TrenchSBR technology provides superior avalanche
capability versus schottky diodes, ensuring more rugged and
reliable end applications.
Reduced ultra-low forward voltage drop (V
F
); Better efficiency
and cooler operation.
Reduced high temperature reverse leakage and increased
reliability against thermal runaway failure in high temperature
operation.
Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)
Halogen and Antimony Free. “Green” Device (Note 3)
Qualified to AEC-Q101 Standards for High Reliability
Description and Applications
The SBRT4U15LP provides very low V
F
and excellent reverse
leakage stability at high temperatures. It is ideal for use as bypass
diode and rectifier, freewheel diode or blocking diode in applications
such as:
Solar Panels
Blocking Diode
Bypass Diode
Boost Diode
Recirculating Diode
