2SD315AI-25

Gate Driver Overview

The 2SD315AI-25 is a dual-channel SCALE-1 driver core designed for IGBTs up to 1700 V. It provides ±15 A gate current, optimized for 200 A to 800 A devices. The unit features electrical isolation between control and power sections with 0/+15 V or ±15 V gate voltage options. Each channel includes programmable Vce monitoring for short-circuit protection. It supports independent or half-bridge modes with internal dead-time generation. An integrated isolated DC/DC converter supplies 3 W per channel.

Gate Driver Feature Summary

• Dual-channel SCALE-1 driver core with transformer isolation
• Programmable Vce monitoring for short-circuit and overcurrent protection
• Integrated isolated DC/DC converter providing 3 W drive power per channel
• Supports direct mode or half-bridge operation with internal dead-time generation

Gate Driver Applications

• Diode-clamped three-level inverters
• Industrial motor drives
• Railway traction systems

Gate Driver Procurement Notes

Verify component authenticity through authorized Power Integrations distributors. Confirm the specific suffix matches design requirements. Check RoHS compliance status as indicated in official documentation. Ensure storage conditions meet manufacturer specifications to maintain reliability. Review datasheet for handling precautions related to high-voltage isolation barriers.

Gate Driver Selection Notes

Select this component for applications requiring robust IGBT protection and high integration. The built-in Vce sensing eliminates external comparator circuits. Verify compatibility with 5V or 15V logic interfaces. Consider the half-bridge mode for space-constrained designs. Ensure thermal management aligns with the specified operating temperature range of -40°C to +85°C.

Gate Driver Part Context

Part of the SCALE-1 series established as an industrial standard since 1999. Manufactured by Power Integrations under the CONCEPT brand. Designed for high-reliability power electronics. Proven in numerous industrial and traction applications. Offers a mature technology platform for gate driving solutions.

Gate Driver Replacement Considerations

Power Integrations recommends using the 2SC0535T for new designs instead of the 2SD315AI-25. The 2SC0435T is also listed as a suggested alternative. Direct substitution requires verification of pinout and functional equivalence.
