15SQ060 Description

15SQ060 is a high-efficiency, fast rectifier diode belonging to the Schottky Barrier Diode (SBD) series. With the low forward voltage drop and fast switching characteristics, it is widely used in various power conversion and power management circuits.

Main Technical Parameters

  • Maximum reverse voltage (VRRM): 60V
  • Average forward rectifier current (IO): 15A
  • Forward voltage drop (VF): Typical value 0.7V (at 7.5A, 25°C)
  • Maximum reverse leakage current (IR): 0.05mA (at rated reverse voltage and 25°C)
  • Operating junction temperature range (TJ): -55°C to +150°C
  • Package: R-6/P-600 package

Features

  • The Plastic Package Carries Underwriters Laboratory
  • Flammability Classification 94V-0
  • Guardring For Overvoltage Protection
  • Low Reverse Leakage
  • High Forward Surge Current Capability

Typical Applications

  • Switching Power Supply (SMPS): used as output rectifier diode, especially in DC-DC converters with low voltage and high current output.
  • Polarity Protection Circuit: prevents damage to the circuit caused by reverse power connection.
  • Flyback Diode: provides a current follow-up path in the inductive load switching circuit.
  • High Frequency Rectification Circuit: uses its fast recovery characteristics for high frequency rectification.
  • Solar Cell System: used to prevent reverse current flow.

Notes

  • Temperature management: Although 15SQ060 has good temperature characteristics, heat dissipation still needs to be considered when applying high current. If necessary, a heat sink needs to be installed.
  • Voltage margin: Sufficient voltage margin should be left during design to avoid damage to the device due to transient overvoltage.
  • Welding temperature: When manually soldering, the soldering iron temperature should not exceed 300°C, and the soldering time should be controlled within 3 seconds.
  • Static protection: Schottky diodes are sensitive to static electricity, and appropriate anti-static measures should be taken during operation.

Comparison With Other Diodes

Compared with ordinary rectifier diodes such as the 1N5400 series, 15SQ060 has a lower forward voltage drop and faster switching speed, but a slightly larger reverse leakage current. Compared with ultrafast recovery diodes, 15SQ060 has better forward characteristics, but slightly inferior reverse recovery characteristics.

Conclusion

15SQ060 Schottky diodes occupy an important position in modern electronic power supply design due to their excellent performance. When selecting this device, design engineers should fully consider the matching degree between its electrical characteristics and specific application requirements to give full play to its performance advantages, while paying attention to its usage restrictions to ensure long-term and reliable operation of the circuit.
