FST12035

Diode Arrays Overview

The GeneSiC Semiconductor FST12035 is a silicon power Schottky diode module rated for a repetitive peak reverse voltage of 35 V and an average forward current of 120 A per package. It features a maximum instantaneous forward voltage of 0.70 V at Tj = 150 °C and supports a peak forward surge current of 1000 A. The device operates within a junction temperature range of -55 °C to 150 °C and provides a thermal resistance from junction to case of 0.80 °C/W per leg.

Diode Arrays Feature Summary

• High surge capability with robust handling of non-repetitive forward currents
• Electrical isolation provided between the semiconductor elements and the mounting plate
• Low sensitivity to electrostatic discharge events during handling

Diode Arrays Applications

• High-efficiency DC-DC converter circuits
• Freewheeling rectification in synchronous buck topologies
• Output rectification in high-current power supply modules

Diode Arrays Procurement Notes

Verify that the specific part number matches the required 35 V reverse voltage rating, as the series includes variants with different blocking voltages. Confirm the TO-249AB package dimensions align with the intended heatsink interface. Ensure compliance with RoHS directives if applicable to the target market requirements.

Diode Arrays Selection Notes

Select this component when designing systems requiring high current density and low conduction losses at elevated temperatures. The 0.80 °C/W thermal resistance allows for efficient heat dissipation without excessive heatsinking. Consider the 35 V rating to ensure adequate margin against transient voltage spikes in the application circuit.

Diode Arrays Part Context

This device belongs to the FST120xx family of silicon power Schottky diodes manufactured by GeneSiC Semiconductor. The family shares identical physical packages and thermal characteristics while varying in reverse voltage ratings from 20 V to 40 V. This specific model represents the 35 V variant within the lineup.

Diode Arrays Replacement Considerations

Direct substitutes include other models from the same FST120xx series with matching 120 A current ratings. Verify that alternative components maintain the same TO-249AB footprint and 0.80 °C/W thermal resistance for direct board replacement.
