FST16050

Diode Arrays Overview

The FST16050 is a silicon Schottky barrier rectifier from the Microsemi FST16035-FST16050 series, housed in an electrically isolated TO-249 package. It features a common cathode configuration with two elements per package. Key electrical ratings include a maximum repetitive peak reverse voltage of 50 V and an average forward current of 80 A per leg (160 A per package). The device supports a maximum non-repetitive surge current of 1200 A. Thermal characteristics specify a junction-to-case resistance of 0.5°C/W and a case-to-sink resistance of 1.0°C/W.

Diode Arrays Procurement Notes

Verify the specific ordering suffix against the datasheet table to confirm the internal configuration. Suffix 'A' indicates a Common Anode variant, while 'D' denotes a Doubler configuration. Standard units are Common Cathode. Confirm RoHS compliance status for the specific batch as manufacturing revisions may affect material declarations.

Diode Arrays Selection Notes

Select this component when a 50 V blocking capability is required alongside high current handling. The TO-249 flange mount package allows for efficient thermal dissipation via direct heatsinking. Ensure the application operates within the specified -55°C to 175°C junction temperature range and respects the 80 A per leg continuous current limit under appropriate cooling conditions.

Diode Arrays Part Context

This part belongs to the FST160xx family of Schottky Powermods manufactured by Microsemi. The series offers standardized mechanical dimensions across variants with different voltage ratings ranging from 35 V to 50 V. These devices are engineered for general-purpose power conversion applications requiring reliable rectification in compact industrial enclosures.

Diode Arrays Replacement Considerations

Cross-reference with FST16035, FST16040, and FST16045 if lower voltage ratings suffice. Verify pinout compatibility for TO-249 packages before substitution. Check equivalent thermal resistance values to ensure adequate heat sinking is maintained.

Diode Arrays FAQ
