STGAP2SM

Isolators - Gate Drivers Overview

The STGAP2SM is a galvanically isolated single gate driver manufactured by STMicroelectronics. It features a 4 A sink/source current capability and rail-to-rail outputs, designed for high-power inverter applications such as industrial motor drivers. The device supports a high voltage rail up to 1700 V and offers dV/dt transient immunity of ±100 V/ns across the full temperature range. It operates within a junction temperature range of -40°C to +150°C and is available in an SO-8 package.

Isolators - Gate Drivers Feature Summary

• Provides galvanic isolation between low-voltage control circuits and high-power switching devices
• Delivers high peak drive current suitable for fast-switching power semiconductors
• Ensures signal integrity during rapid voltage transitions with high common-mode rejection

Isolators - Gate Drivers Applications

• Industrial motor drives
• High-power inverters
• Solid-state transformers

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix (e.g., TR for reel packaging) against the required logistics configuration. Confirm RoHS compliance status via the official datasheet before integration. Ensure the selected variant matches the intended thermal management strategy for the SO-8 package. Cross-reference the ordering code with the manufacturer's latest documentation to avoid obsolete revisions.

Isolators - Gate Drivers Selection Notes

Select this component when designing systems requiring robust isolation for IGBTs or SiC MOSFETs. Evaluate the 4 A drive strength against the target switch's gate charge requirements. Consider the ±100 V/ns immunity for noisy environments typical in industrial automation. Verify that the 1700 V blocking capability aligns with the DC bus voltage of the application.

Isolators - Gate Drivers Part Context

This part belongs to the STGAP2S family of isolated gate drivers from STMicroelectronics. The family focuses on providing reliable isolation for power electronics in demanding industrial settings. The STGAP2SM specifically represents the tube-packaged version of this single-channel driver, distinct from tape-and-reel variants like the STGAP2SMTR.

Isolators - Gate Drivers Replacement Considerations

Check for direct pin-compatible alternatives within the STGAP2S series, such as the STGAP2SICSNCTR, if reel packaging is preferred. Verify electrical parameters match exactly when considering cross-manufacturer substitutes.
