2SD315AI

MEDIUM/HIGH-POWER DUAL SCALE DRIVER CORE

Highly approved SCALE technology

The award-winning drive circuit for IGBTs

2SD315AI for 600V to 1700V IGBTs up to 800A
2SD315AI-25 for 2500V IGBTs up to 400A
2SD315AI-33 for 3300V IGBTs up to 200A

Short Description

The 2SD315AI series comprises highly approved 2-channel SCALE driver cores for IGBTs up to 1700V (optionally up to 3300V). Its gate current capability of ±15A is optimized for IGBTs from 200A to typically 800A. The two drive channels feature electrical isolation between the control electronics and the power section. The gate voltage is 0/+15V or ±15V.

Each channel is equipped with a programmable Vce monitoring function for protection against short circuit and overcurrent.

The driver is equipped with the award-winning CONCEPT SCALE driver chipset and can be operated in two modes: either with two independent driver channels or as a half-bridge driver with internal dead-time generation.

The integrated electrically insulated DC/DC converter supplies a drive power of 3W per channel.

Reliability

The 2SD315AI has been established on the market as an industrial standard since 1999. The driver has been tried and tested within hundreds of thousands of industrial and traction applications. The calculated MTBF according to MIL Hdbk 217F is 10 million hours at 40ºC. According to field data, the actual reliability is even higher.
