SR5150 Description

SR5150 is a Schottky Barrier Rectifier diode in DO-201 package (axial lead package). It has the characteristics of low forward voltage drop and high switching speed. It is widely used in switching power supplies, DC-DC converters, polarity protection and other occasions.

DO-201 package is an axial package and suitable for through-hole technology (THT).It is convenient for manual soldering and PCB board installation.

Technical Parameters

  • Package: DO-201
  • Maximum reverse voltage (VR): 150V
  • Average rectified current (IF): 5A
  • Peak surge current (IFSM): 150A (8.3ms single cycle sine wave)
  • Forward voltage drop (VF): 0.9V (@5A)
  • Reverse leakage current (IR): ≤ 0.05mA (@100V, 25°C)
  • Operating temperature range: -55°C ~ +150°C
  • Storage temperature range: -55°C to +150°C

Structure Description

  • Metal-semiconductor junction: uses metal (such as platinum) to contact semiconductor (N-type silicon) to form rectification characteristics
  • No minority carrier storage effect: extremely fast switching speed
  • Low barrier height: lower forward voltage drop

Features and Advantages

  • Low forward voltage drop: lower than ordinary silicon diodes, reducing conduction losses and improving efficiency
  • Fast switching characteristics: no minority carrier storage effect, suitable for high-frequency rectification (such as switching power supplies)
  • High temperature stability: can work stably in a wide temperature range
  • DO-201 package: high mechanical strength, good heat dissipation performance, suitable for PCB through-hole welding

Applications

  • Switching mode power supply (SMPS)
  • DC-DC converter
  • Polarity protection
  • Solar photovoltaic system

Summary

SR5150 (DO-201) is a cost-effective Schottky diode suitable for switching power supplies, DC-DC conversion, polarity protection, etc. Its low VF, fast switching, and DO-201 package make it an ideal choice for medium power rectification.
