The ISL9V3040S3ST is a 400 V, N-channel ignition IGBT from onsemi's ECOSPARK family. It features a D2PAK (TO-263) surface-mount package and supports a continuous collector current of 21 A at 25°C case temperature. The device includes an internal diode for voltage clamping and offers a short-circuit withstand capability of 300 mJ at 25°C junction temperature. Key electrical parameters include a maximum collector-emitter breakdown voltage of 430 V, a typical saturation voltage of 1.25 V at 6 A, and a gate charge of 17 nC. It operates within a junction temperature range of -40°C to 175°C.
Verify the specific suffix against the manufacturer's ordering information to ensure correct packaging and shipping configuration. Confirm that the component meets RoHS compliance requirements and check for any recent product change notices or assembly lot variations before finalizing procurement specifications.
Select this component for automotive ignition systems requiring robust short-circuit immunity and integrated clamping. Ensure the thermal management design accommodates the specified power dissipation limits and derating curves. Validate that the gate drive voltage aligns with the logic-level input requirements for optimal switching performance.
This part belongs to the ISL9V3040 series, which also includes variants in DPAK and TO-220 packages. It is designed as a next-generation ignition IGBT offering improved short-circuit withstand capabilities compared to previous generations while maintaining a compact form factor suitable for space-constrained automotive modules.
Direct substitutes within the same series include ISL9V3040D3ST and ISL9V3040P3, differing primarily in package type. Verify pinout compatibility and thermal resistance characteristics when considering alternative packages for the same application.
