DSTF20150CR

Diode Arrays Overview

The Littelfuse DSTF20150CR is a Schottky barrier rectifier diode array featuring a common anode configuration with two individual diodes. It is housed in a TO-220-3 (ITO-220A) through-hole package with an isolated tab for thermal management. The device supports a maximum repetitive peak reverse voltage of 150 V and a continuous forward current of 10 A per diode, totaling 20 A for the pair. It exhibits a low forward voltage drop to minimize conduction losses. The component operates within a junction temperature range up to 150°C and withstands a forward surge current of 150 A.

Diode Arrays Feature Summary

• Ultra-low forward voltage design for enhanced efficiency
• High-frequency operation capability
• Common anode dual diode structure

Diode Arrays Applications

• DC-DC converters
• Free-wheeling applications
• Power supply output rectification

Diode Arrays Procurement Notes

Verify the specific ordering suffix 'CR' corresponds to the required tape-and-reel packaging format rather than bulk or full-pack configurations. Confirm that the ITO-220A lead form matches the target PCB footprint requirements. Ensure the selected variant meets the necessary thermal resistance specifications for the intended heat sink application.

Diode Arrays Selection Notes

Select this component when high-efficiency rectification at moderate voltages is required. The common anode topology simplifies circuit design for synchronous rectification or free-wheeling paths. Consider the TO-220 package size constraints and the need for an isolated mounting surface when designing the mechanical assembly.

Diode Arrays Part Context

This part belongs to the Littelfuse DST series of Ultra Low VF Schottky Barrier Rectifiers. The series is engineered to meet general requirements for high-efficiency power conversion. The DSTF20150CR specifically addresses applications needing robust current handling with minimal voltage drop in a standard through-hole form factor.

Diode Arrays Replacement Considerations

Direct substitutes include other 150V 10A/20A common anode Schottky diodes in TO-220 packages from manufacturers such as Vishay or ON Semiconductor. Verify pinout compatibility and thermal characteristics before substitution.
