SF1603PTH

Diode Arrays Overview

The SF1603PTH is a 16.0 Ampere glass-passivated super fast rectifier manufactured by Taiwan Semiconductor Corporation. It features a maximum repetitive peak reverse voltage of 30 Volts and a maximum average forward rectified current of 16 Amperes at 50°C. The device exhibits a typical fast recovery time of 50 nanoseconds with a peak reverse recovery current of 35 Amperes. It is housed in the DO-201AD (DO-4) axial leaded package, designed for high-efficiency applications requiring low forward voltage drop and high surge current capability.

Diode Arrays Feature Summary

• Glass passivation provides mechanical strength and protection against moisture and chemical corrosion.
• Super-fast recovery characteristics minimize switching losses and improve system efficiency.
• Low forward voltage drop reduces power dissipation and heat generation during operation.

Diode Arrays Applications

• Low voltage, high frequency inverters
• Free wheeling diodes in motor drive circuits
• Polarity protection circuits

Diode Arrays Procurement Notes

Verify the specific suffix 'PTH' to confirm the axial leaded packaging variant, as standard equivalents may differ in form factor. Ensure the supplier provides documentation confirming compliance with RoHS directives if required for your assembly process. Cross-reference the manufacturer's official datasheet for the SF1603 series to validate electrical parameters against your circuit requirements before finalizing procurement.

Diode Arrays Selection Notes

Select this component when designing circuits that require high current handling up to 16 Amperes with rapid switching speeds. The 30V reverse voltage rating suits low-voltage DC-DC converters and power supplies. Consider the thermal management capabilities of the DO-201AD package for your specific heat dissipation needs. Compare the 50ns recovery time against slower rectifiers to ensure compatibility with high-frequency switching operations.

Diode Arrays Part Context

This part belongs to the SF1603 series of super fast rectifiers from Taiwan Semiconductor Corporation. The series is characterized by high reliability and efficiency in power conversion applications. The SF1603PTH specifically denotes the axial leaded version, distinguishing it from surface-mount variants within the same electrical family. It is engineered for robust performance in industrial and consumer power electronics.

Diode Arrays Replacement Considerations

Equivalent parts include the SF1603G from Luguang or Won-Top Electronics, which share identical electrical specifications and glass-passivated construction. Verify pinout compatibility and physical dimensions when substituting to ensure proper fitment on existing PCB layouts or through-hole assemblies.
