STPS30L45CG-TR

Diode Arrays Overview

The STPS30L45CG-TR is a dual common cathode Schottky rectifier from the STPS3045C series, manufactured by STMicroelectronics. It features a peak repetitive reverse voltage (Vrrm) of 45 V and a maximum continuous forward current (If) of 30 A. The device utilizes a surface-mount TO-263 package with three pins. Key electrical parameters include a maximum forward voltage (Vf) of 840 mV, a peak reverse leakage current (Ir) of 40 mA, and a peak non-repetitive forward surge current (Ifsm) of 220 A. It operates within a junction temperature range of -65°C to 175°C.

Diode Arrays Feature Summary

• Dual common cathode configuration for center-tap applications
• Low forward voltage drop to minimize conduction losses
• Low switching losses suitable for high-frequency operation
• Avalanche rated capability

Diode Arrays Applications

• Switched mode power supplies
• High frequency DC to DC converters
• Free wheeling diodes in low voltage inverters
• Polarity protection circuits

Diode Arrays Procurement Notes

Verify the specific suffix 'G-TR' against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging specifications and RoHS compliance status. Ensure the ordering quantity aligns with the manufacturer's standard reel size requirements. Cross-reference the component marking with the latest production notices to avoid counterfeit or obsolete stock.

Diode Arrays Selection Notes

Select this component when a dual Schottky rectifier with a 45 V rating and 30 A total current capacity is required in a surface-mount TO-263 package. It is appropriate for designs prioritizing low conduction losses and high efficiency in compact power supply architectures. Consider thermal management requirements given the 175°C maximum junction temperature rating.

Diode Arrays Part Context

This part belongs to the STPS30L45C family of dual low-drop power Schottky rectifiers. The family includes variants in different packages such as TO-220FP and TO-247. The 'CG-TR' designation indicates the specific surface-mount variant with green molding compound and tape-and-reel packaging, distinguishing it from through-hole versions like the STPS30L45CT.

Diode Arrays Replacement Considerations

Direct substitutes within the same series include STPS30L45C variants in different packages, such as STPS30L45CT (TO-220-3). For equivalent performance in surface-mount applications, verify compatibility with other manufacturers' 45V 30A dual Schottky diodes in TO-263 packages, ensuring pinout and thermal characteristics match.
