Overview

The FOD8318 is an advanced 2.5 A output current IGBT drive optocoupler, capable of driving most 1200 V / 150 A IGBTs. It is ideally suited for fast-switching driving of power IGBTs and MOSFETs used in motor control inverter applications and high-performance power systems. It consists of an integrated gate drive optocoupler featuring low RDS(ON) CMOS transistors to drive the IGBT from rail to rail and an integrated high-speed isolated feedback for fault sensing. The FOD8318 has an active Miller clamp fuction to shut off the IGBT during a high dv/dt situation without the need of a negative supply voltage. It offers critical protection features necessary for preventing fault conditions that lead to destructive thermal runaway of IGBTs.
It utilizes ON Semiconductor’s proprietary coplanar Optoplanar® packaging technology , and optimized IC design to achieve high noise immunity, characterized by high common mode rejection and power supply rejection specifications.
The device is housed in a compact 16-pin small outline plastic package that meets the 8 mm creepage and clearance requirements.

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
