Description and Applications
The SBRT3U45SA is a 3A 45V single rectifier packaged in the low
profile SMA package. Providing very low VF and excellent reverse
leakage stability at high temperatures, this device is ideal for use in
general rectification applications such as:
• Boost Diode
• Blocking Diode
• Recirculating Diode
