DSTB30200C

Diode Arrays Overview

The Littelfuse DSTB30200C is a dual Schottky barrier rectifier in a TO-263 (D2PAK) package. It features a common cathode configuration with two independent legs, each rated for an average forward current of 15A and a peak repetitive reverse voltage of 200V. The total device handles 30A. Key electrical parameters include a maximum forward voltage drop of 1.10V at 15A and 25°C, and a surge current rating of 200A per leg. Thermal resistance from junction to case is 2.0°C/W per leg.

Diode Arrays Procurement Notes

Verify the specific ordering suffix and marking code against the manufacturer's official datasheet before procurement. Confirm that the component is supplied in tape-and-reel packaging as specified. Ensure the requested quantity aligns with the minimum order quantity requirements defined by the distributor or manufacturer. Cross-reference the date code and lot number to verify manufacturing recency and compliance with RoHS standards.

Diode Arrays Selection Notes

Select this component when high-frequency switching applications require low conduction losses and efficient heat dissipation via a surface-mount package. The common cathode arrangement simplifies circuit design for dual-rail or bridge configurations. Evaluate thermal management needs based on the 2.0°C/W junction-to-case resistance to ensure the operating temperature remains within the -55°C to +150°C range under expected load conditions.

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 commercial and industrial requirements by offering high-temperature performance, low leakage current, and reduced forward voltage. The 'B' in the model name indicates the D2PAK package type, while '30' denotes the total forward current capacity and '200' specifies the voltage rating.

Diode Arrays Replacement Considerations

Consult the official Littelfuse replacement guide for verified substitutes. Ensure any alternative maintains the same TO-263 footprint, common cathode pinout, and equivalent electrical ratings for voltage and current handling.
