STL7LN80K5

Single FETs, MOSFETs Overview

The STL7LN80K5 is an N-channel Power MOSFET from STMicroelectronics, utilizing MDmesh K5 technology. It features a drain-source voltage (Vdss) of 800 V and a continuous drain current (Id) of 5 A at case temperature. The device offers a typical on-resistance (Rds(on)) of 0.95 Ohms and a maximum gate charge (Qg) of 12 nC at 10 V. It is housed in a PowerFLAT 5x6 VH surface-mount package with a thermal dissipation capacity of 42 W. The component operates within a junction temperature range of -55°C to +150°C.

• 100% avalanche tested to ensure robustness under inductive switching conditions.

Single FETs, MOSFETs Applications

• High-voltage power conversion circuits
• Industrial motor control systems
• Uninterruptible power supply (UPS) units

Single FETs, MOSFETs Procurement Notes

Verify the specific suffix 'K5' corresponds to the PowerFLAT 5x6 VH package variant when sourcing. Confirm RoHS3 compliance status as per the latest manufacturer documentation. Ensure ESD handling protocols are followed due to the sensitive gate structure. Cross-reference the datasheet revision date to validate electrical parameters against current production batches.

Single FETs, MOSFETs Selection Notes

Select this component for applications requiring high voltage blocking capability combined with low switching losses. The surface-mount PowerFLAT package facilitates automated assembly and improved thermal performance compared to through-hole alternatives. Consider the 800 V rating for mains-connected or high-side switch configurations where standard silicon limits are exceeded.

Single FETs, MOSFETs Part Context

This part belongs to the STL7LN80 series, which shares the MDmesh K5 architecture but varies in current ratings and packaging. Unlike the STF3LN80K5 in TO-220FP or STU7LN80K5 in IPAK, this model utilizes a compact surface-mount form factor designed for space-constrained PCB layouts while maintaining comparable electrical characteristics.

Single FETs, MOSFETs Replacement Considerations

Direct substitutes include other MDmesh K5 devices with similar 800 V ratings, such as STL10LN80K5, provided the package footprint matches. Verify that alternative components meet the same 12 nC gate charge specification to maintain switching timing compatibility in existing designs.
