STGAP3S6I

Isolators - Gate Drivers Overview

The STGAP3S6I is a galvanically isolated single-channel gate driver from the STGAP3S series, designed for high-voltage applications up to 1200 V. It utilizes capacitive coupling technology to provide isolation between the low-voltage control interface and the high-voltage power stage. The device features an output current capability of 6 A source and 10 A sink. It operates within a supply voltage range of 3.1 V to 5.5 V and supports a working temperature range from -40°C to 125°C. Key electrical parameters include a maximum propagation delay of 95 ns, typical rise and fall times of 20 ns and 18 ns respectively, and a minimum common-mode transient immunity of 200 V/ns. The component is housed in a 16-SOIC package with a 5700 Vrms isolation voltage rating.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix (e.g., STR) against the required tape-and-reel packaging if automated assembly is planned, as bulk packaging may be standard for some variants. Confirm that the 16-SOIC footprint matches the PCB design constraints. Ensure the input signal levels are compatible with the 3.1 V to 5.5 V supply range. Check for any specific certification requirements such as UL listing which may be relevant for end-product compliance. Validate thermal management solutions given the 125°C operating limit.

Isolators - Gate Drivers Selection Notes

Select this component when a single-channel isolated driver with asymmetric current drive (6A source/10A sink) is required. It is suitable for designs needing high dv/dt immunity and integrated fault protection. Consider the 16-SOIC package size for space-constrained layouts. Compare with other STGAP3S variants if different current ratings or packaging options are needed. Ensure the application voltage does not exceed the 1200 V rail specification.

Isolators - Gate Drivers Part Context

The STGAP3S6I belongs to the STGAP3S family of isolated gate drivers from STMicroelectronics. This series is engineered for demanding power electronics applications, offering enhanced reliability through capacitive isolation. The family includes variants with different output currents and packaging styles, all sharing core features like desaturation protection and high common-mode transient immunity. The STGAP3S6I specifically targets applications requiring a balance of moderate source current and higher sink current capabilities.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes within the same series include STGAP3S6S, STGAP3SX I, and STGAP3SXS, which share similar functional characteristics but may differ in packaging or minor electrical specifications. Verify pinout compatibility and isolation voltage ratings before substitution.
