2SD315AI UL

Gate Driver Overview

The 2SD315AI UL is a dual-channel SCALE-1 driver core for IGBTs up to 1700 V (optionally to 3300 V). It provides ±18 A gate current, optimized for 200 A to 800 A devices. The driver features electrical isolation between control and power sections with 0/+15 V or ±15 V gate voltage. Each channel includes programmable Vce-monitoring for short-circuit protection. It operates in direct or half-bridge modes with internal dead-time generation. An integrated isolated DC/DC converter supplies 6 W drive power per channel.

Gate Driver Feature Summary

• Dual-channel SCALE-1 driver core with transformer isolation
• Integrated isolated DC/DC converter providing high drive power
• Programmable Vce-monitoring for short-circuit and overcurrent protection
• Supports direct mode or half-bridge operation with internal dead-time

Gate Driver Applications

• Industrial motor drives
• Traction applications
• Uninterruptible power supply systems
• Induction heating equipment

Gate Driver Procurement Notes

Verify the specific suffix designation against official Power Integrations documentation to confirm exact electrical characteristics and isolation ratings. Ensure the component meets required safety certifications for the target application environment. Confirm availability status as this series may be subject to lifecycle changes.

Gate Driver Selection Notes

Select this component for applications requiring robust isolation and integrated protection for medium-to-high power IGBTs. Consider the ±18 A output capability for driving large modules. Evaluate the need for half-bridge functionality versus independent channel operation when designing the control interface.

Gate Driver Part Context

This part belongs to the SCALE-1 family of gate drivers from Power Integrations. It is designed for high-reliability industrial and traction environments. The series has been established as an industry standard since 1999, offering proven performance in demanding power conversion scenarios.

Gate Driver Replacement Considerations

Public confirmed substitute part numbers include 2SC0435T and 2SC0535T. These are suggested alternatives for new designs due to potential lifecycle status of the 2SD315AI series.
