MBR2545CTH

Diode Arrays Overview

The MBR2545CTH is a Schottky barrier rectifier diode array manufactured by onsemi. It features a single pair common cathode configuration housed in a TO-220-3 through-hole package. The device is rated for a maximum repetitive peak reverse voltage of 45 V and a continuous forward current of 15 A. Key electrical parameters include a maximum forward voltage of 620 mV at 15 A and a maximum reverse current of 1 μA. It supports a non-repetitive peak forward surge current of 200 A and operates within a junction temperature range up to 175 °C, ensuring reliable performance in switch-mode power applications.

Diode Arrays Feature Summary

• Schottky barrier technology provides low forward voltage drop for improved efficiency.
• Common cathode dual-diode configuration simplifies circuit design for center-tap or full-wave rectification.
• Guardring structure offers enhanced stress protection and robustness.

Diode Arrays Applications

• Switch-mode power supplies (SMPS)
• Free-wheeling diodes in DC-DC converters
• Polarity protection circuits

Diode Arrays Procurement Notes

Verify the exact ordering suffix against the official onsemi datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the TO-220-3 lead form matches the target PCB footprint requirements. Cross-reference the thermal resistance values with the intended heatsinking strategy to maintain junction temperatures within the specified 175 °C limit during operation.

Diode Arrays Selection Notes

Select this component when a 45 V reverse voltage rating and 15 A continuous current capacity are required in a through-hole format. The low forward voltage characteristic makes it suitable for applications prioritizing efficiency over minimal cost. Ensure the operating environment does not exceed the maximum junction temperature specification and that the surge current demands remain below the 200 A non-repetitive limit.

Diode Arrays Part Context

This part belongs to onsemi's MBR series of Schottky rectifiers, designed for general-purpose high-efficiency rectification. The MBR2545CTH specifically addresses needs for medium-current applications where low conduction losses are critical. It complements other variants in the family offering different voltage or current ratings while maintaining the same reliable TO-220 package style for easy integration into existing power supply designs.

Diode Arrays Replacement Considerations

Direct substitutes must match the 45 V, 15 A, common cathode, TO-220-3 specifications. Verify equivalent forward voltage and reverse leakage characteristics to ensure no performance degradation in the target application.
