DSTF3045C

Diode Arrays Overview

The Littelfuse DSTF3045C is a Schottky Barrier Rectifier featuring a dual common cathode configuration housed in an ITO-220AB package. It provides a peak inverse voltage of 45V and supports a total average forward current of 30A, with 15A per leg at a case temperature of 90°C. The device exhibits low forward voltage drop, typically ranging from 0.44V to 0.57V depending on current and junction temperature. It operates within a junction temperature range of -55°C to +150°C and includes a thermal resistance of 5.0°C/W per leg.

Diode Arrays Procurement Notes

Verify the specific package variant against the datasheet, as the DSTF series also includes D2-PAK and TO-220AB options. Confirm that the required configuration matches the common cathode setup specified for the DSTF3045C model. Ensure thermal management aligns with the 5.0°C/W junction-to-case rating. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Diode Arrays Selection Notes

Select this component when designing circuits requiring high-frequency rectification with minimal conduction losses. The dual common cathode layout simplifies board space requirements compared to discrete single diodes. Consider the 45V reverse voltage rating to ensure adequate headroom for transient spikes in low-voltage applications. Evaluate thermal dissipation needs based on the 15A per leg continuous current limit.

Diode Arrays Part Context

The DSTF3045C belongs to Littelfuse's DST series of ultra-low VF Schottky Barrier Rectifiers. This series is engineered to meet commercial and industrial standards by offering high junction temperature capabilities and reduced leakage currents.
