6SD106EI

Gate Driver Overview

The 6SD106EI is a discontinued six-channel SCALE-1 driver core designed for IGBTs up to 1700 V. It provides ±6 A gate current capability, optimized for IGBTs rated from 50 A to typically 200 A. The device features electrical isolation between control electronics and the power section with a ±15 V gate voltage. Each channel includes programmable Vce-monitoring for short-circuit and overcurrent protection. An integrated isolated DC/DC converter supplies 1 W per channel. Operating temperatures range from -40 °C to +85 °C, with rise and fall times of 100 ns and 80 ns respectively.

Gate Driver Feature Summary

• Integrated isolated DC/DC converter providing 1 W drive power per channel
• Programmable Vce-monitoring function for short-circuit and overcurrent protection on each channel
• Compatible with 5 V to 15 V logic level Schmitt-trigger inputs

Gate Driver Applications

• Industrial applications requiring high reliability
• Rail applications utilizing IGBT modules
• Systems employing IGBTs rated up to 1700 V
• IGBTs with current ratings from 50 A to typically 200 A

Gate Driver Procurement Notes

The 6SD106EI is officially listed as an End-of-Life (EOL) product by Power Integrations and is no longer available for new designs. Verification of discontinuation status is required through official manufacturer notifications or authorized distributor archives. Sourcing this component may involve limited remaining stock or secondary market channels. Engineers must confirm availability and lead times carefully, as standard supply chains do not support active procurement. Replacement strategies should be prioritized due to the confirmed production halt.

Gate Driver Selection Notes

This component belongs to the SCALE-1 driver series, established as an industrial standard since 1999. It supports operation in two modes: two independent driver channels or half-bridge configuration with internal dead-time generation. The design emphasizes reliability and long service life, proven in numerous industrial and rail environments. Selection should consider the specific need for six-channel isolation and the ±15 V gate drive requirement. Compatibility with IGBTs up to 1700 V and peak currents of ±6 A defines its operational envelope. Alternative solutions within the same family may offer updated features.

Gate Driver Part Context

The 6SD106EI is part of the 6SD106 series of six-channel SCALE-1 driver cores manufactured by Power Integrations under the CONCEPT brand. These drivers are engineered for high-voltage IGBT applications, providing robust signal isolation and protection mechanisms. The series utilizes transformer isolation for signal transmission and includes status feedback capabilities. This specific model represents a mature technology platform focused on stability and integration for complex power switching systems.

Gate Driver Replacement Considerations

Power Integrations suggests the 2SC0108T as a suggested alternative for the 6SD106EI. Users should verify pinout compatibility and functional equivalence before substitution.
