2SD315AI

Gate Driver Overview

The 2SD315AI is a dual-channel SCALE-1 driver core designed for IGBTs up to 1700 V, with optional support for 3300 V devices. It provides ±15 A gate current, optimized for IGBTs ranging from 200 A to typically 800 A. The device features electrical isolation between control electronics and the power section, supporting gate voltages of 0/+15 V or ±15 V. Each channel includes programmable Vce-monitoring for short-circuit and overcurrent protection. It operates in direct mode or half-bridge mode with internal dead-time generation. An integrated isolated DC/DC converter supplies 3 W per channel.

Gate Driver Procurement Notes

Verify component authenticity through authorized Power Integrations distributors. Confirm package type and suffix variations match design requirements. Check for obsolescence notices as this part may be superseded by newer series. Ensure supply chain stability due to potential discontinuation status.

Gate Driver Selection Notes

Select based on required blocking voltage (1700 V standard, 3300 V optional) and gate current needs (±15 A). Consider interface compatibility with 5 V or 15 V logic levels. Evaluate thermal management requirements for the isolated DC/DC converter. Verify if half-bridge mode with internal dead-time meets timing specifications.
