DSB40C15PB

Diode Arrays Overview

The IXYS DSB40C15PB is a dual common cathode Schottky diode array housed in a TO-220AB-3 through-hole package. It features a maximum repetitive peak reverse voltage of 15 V and an average forward current of 20 A per element. The device exhibits a low maximum forward voltage of 390 mV at rated conditions, ensuring minimal conduction losses. It supports a high non-repetitive peak surge current of 300 A and operates reliably within a junction temperature range of -65°C to +175°C.

Diode Arrays Feature Summary

• Dual common cathode configuration for efficient bridge rectification or polarity protection
• Low forward voltage drop minimizes power dissipation and thermal stress
• High surge current capability handles transient load spikes effectively
• Extended operating junction temperature range ensures robust performance

Diode Arrays Applications

• DC-DC converter output rectification
• Free-wheeling diodes in switching power supplies
• Polarity protection circuits
• Battery charging systems

Diode Arrays Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout compatibility and electrical tolerances. Ensure the procurement channel provides valid traceability documentation. Confirm that the component meets RoHS compliance requirements if mandated by the design specifications. Cross-reference the package marking with the official identification guide to prevent counterfeit substitution.

Diode Arrays Selection Notes

Select this component when low forward voltage drop is critical for efficiency in low-voltage applications. The dual common cathode structure simplifies circuit layout compared to discrete single diodes. Evaluate the thermal resistance of the TO-220AB-3 package against the expected heat dissipation requirements. Consider the 15 V reverse voltage rating to ensure adequate margin over the maximum operating voltage.

Diode Arrays Part Context

This part belongs to the HiPerFRED or similar high-performance Schottky series from IXYS, designed for fast recovery and low loss. It complements other power management components like MOSFETs and IGBTs in complete power conversion stages. The dual configuration reduces component count and board space compared to using two separate single diodes.
