The ISL9V3040D3STV is an N-channel Ignition IGBT from the ECOSPARK series, manufactured by onsemi. It features a 400 V collector-emitter breakdown voltage and a continuous collector current of 21 A at 25°C. The device delivers a specific switching energy (SCIS) of 300 mJ at 25°C junction temperature. Key electrical parameters include a maximum collector-emitter saturation voltage of 1.25 V and a gate-emitter voltage range of -10 V to +10 V. It operates within a junction temperature range of -55°C to +175°C and dissipates up to 150 W of power. The component is housed in a DPAK-3 (TO-252-3) surface-mount package and holds AEC-Q101 qualification.
Verify the exact suffix F085C or similar against the datasheet revision to confirm packaging and tape-and-reel specifications. Ensure the procurement channel provides original manufacturer documentation to validate AEC-Q101 certification status. Cross-reference the part number with official onsemi databases to avoid counterfeit components in automotive supply chains.
Select this component when designing automotive ignition systems requiring 400 V blocking capability and logic-level gate compatibility. Compare the 300 mJ switching energy against alternative devices if thermal management constraints are tight. Verify that the TO-252-3 package fits the PCB layout requirements for the target coil-on-plug or distributorless ignition architecture.
This IGBT belongs to the ECOSPARK family, designed specifically for automotive ignition applications. It succeeds earlier generations like the ISL9V3040D3ST, maintaining similar electrical characteristics while ensuring compliance with modern automotive quality standards. The device integrates robust switching performance with low conduction losses suitable for high-frequency ignition coil driving.
The ISL9V3040D3ST serves as a direct predecessor with identical electrical ratings. Other ECOSPARK variants such as the FGD2040G3-F085 offer different switching energies and packages. Verify pinout compatibility and thermal resistance values before substituting with other 400 V ignition IGBTs.
