STGIPL35K120L1

Overview

The STGIPL35K120L1 is a single-phase Intelligent Power Module (IPM) from the SLLIMM™ series, integrating 35 A, 1200 V short-circuit rugged IGBTs with control ICs for gate driving and free-wheeling diodes. It features an SDIP-18L package with DBC substrate for low thermal resistance and 2500 Vrms isolation. Key electrical parameters include a continuous collector current of 35 A at 25°C case temperature, a maximum pulsed collector current of 70 A, and a short-circuit withstand time of 5 µs. The module includes undervoltage lockout, desaturation detection, active Miller clamp, and fault status output.

Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors or direct channels. Confirm that the specific revision matches the required design specifications, as datasheet details are subject to change. Ensure proper handling procedures are followed due to the sensitive nature of power semiconductor devices. Check for any obsolescence notices or lifecycle status updates before finalizing procurement plans.

Selection Notes

Select this IPM for applications requiring compact AC motor drive solutions with integrated protection. Consider the 35 A continuous current rating and 1200 V blocking voltage for appropriate load matching. Evaluate the thermal management requirements based on the junction-to-case thermal resistance values provided in the datasheet. Ensure the control interface is compatible with the active-low logic inputs and recommended optocoupler or pulse transformer configurations.

FAQ

How does the Active Miller Clamp function?

The Active Miller Clamp monitors the gate voltage during turn-off and activates when the voltage drops below 2 V relative to GND, controlling Miller current and avoiding the need for a negative supply voltage.

What is the purpose of the FAULT pin?

The FAULT pin provides feedback regarding IPM status, signaling events such as desaturation or undervoltage lockout (UVLO). It is designed to drive an optocoupler and resets only when the underlying fault condition disappears.

Can the input be driven by a pulse transformer?

Yes, the input is compatible with both optocouplers and pulse transformers. When using a pulse transformer, the input signal must comply with minimum pulse width and threshold voltage specifications to ensure reliable operation.
