SIS5102QP1HT1G

Hot Swap Controllers Overview

The SIS5102QP1HT1G is a high-voltage silicon carbide (SiC) MOSFET manufactured by onsemi. It features a 1200V drain-source breakdown voltage and a continuous drain current of 51A at 25°C, reducing to 34A at 100°C. The device utilizes a TO-247-4L package with an isolated tab for thermal management. Key electrical characteristics include a maximum gate-source voltage of ±20V and a typical on-resistance of 160mΩ at 25°C. It is designed for high-frequency switching applications requiring low conduction losses.

Hot Swap Controllers Procurement Notes

Verify the specific suffix HT1G corresponds to the required tape-and-reel packaging configuration. Confirm that the TO-247-4L pinout matches the target PCB footprint, particularly the isolated drain terminal. Ensure the procurement channel provides authentic onsemi components to avoid counterfeit devices affecting reliability.

Hot Swap Controllers Selection Notes

Select this component when designing systems operating above 800V where silicon MOSFET efficiency limits are reached. Consider the 51A continuous current rating against the expected load profile and ambient temperature conditions. Evaluate the thermal resistance requirements to ensure the heatsink design can maintain junction temperatures within safe operating limits during peak loads.

Hot Swap Controllers Part Context

This part belongs to onsemi's SiC MOSFET portfolio, which targets next-generation power electronics. The SIS5102 series is positioned for medium-to-high power applications demanding higher switching frequencies than traditional silicon devices allow. It complements other wide-bandgap solutions in the manufacturer's catalog for grid-tied and off-grid energy systems.

Hot Swap Controllers Replacement Considerations

Direct replacements must match the 1200V rating, TO-247-4L package, and similar Rds(on) specifications. Verify compatibility with existing gate drive voltages and thermal interface materials. Cross-reference with other manufacturers' SiC MOSFETs offering comparable dynamic performance and avalanche ruggedness.

Hot Swap Controllers FAQ

What is the maximum operating junction temperature?

The maximum operating junction temperature is typically rated up to 175°C, allowing for robust performance in high-thermal-stress environments.

Does the TO-247-4L package require special mounting considerations?

Yes, the fourth lead is an electrically isolated drain tab. Proper insulation from the heatsink or careful grounding strategies are required to prevent short circuits.
