STD2NK90Z-1

Single FETs, MOSFETs Overview

The STD2NK90Z-1 is an N-channel Power MOSFET from STMicroelectronics utilizing SuperMESH technology. It features a drain-source voltage (Vds) of 900 V and a continuous drain current (Id) of 2.1 A at case temperature. The device has a typical on-resistance (Rds(on)) of 5 Ω and a maximum power dissipation (Pd) of 70 W at case temperature. It operates within a junction temperature range of -55°C to 150°C and is housed in a through-hole IPAK package with three pins.

Single FETs, MOSFETs Feature Summary

• Integrated Zener diode protection between gate and source for enhanced reliability
• SuperMESH technology optimization for minimized gate charge
• High-voltage capability suitable for robust switching applications

Single FETs, MOSFETs Applications

• High-voltage power switching circuits
• General-purpose power management systems
• Industrial control equipment requiring isolated high-side switching

Single FETs, MOSFETs Procurement Notes

Verify the specific suffix '-1' during procurement, as it denotes the integrated Zener protection variant distinct from standard versions like STD2NK90Z. Confirm the IPAK through-hole package requirement against PCB footprint specifications. Ensure thermal management design accounts for the 70 W case temperature dissipation limit rather than free-air ratings.

Single FETs, MOSFETs Selection Notes

Select this component when high-voltage isolation with built-in gate protection is required. Compare Rds(on) and gate charge metrics against other SuperMESH variants if lower conduction losses are critical. Verify that the through-hole IPAK form factor aligns with assembly constraints compared to surface-mount alternatives like TO-252 or TO-220 packages.

Single FETs, MOSFETs Part Context

This part belongs to the SuperMESH family of high-voltage MOSFETs designed by STMicroelectronics. It shares technological roots with devices such as the STP3NK90Z and STD3NK90ZT4 but differs in current rating and package type. The inclusion of the Zener diode distinguishes it from unprotected counterparts within the same voltage class.

Single FETs, MOSFETs Replacement Considerations

Direct substitutes include STD2NK90Z (without Zener) if protection is provided externally. For pin-compatible replacements with similar electrical characteristics, consider other 900 V N-channel MOSFETs in IPAK packages from compatible manufacturers, ensuring Rds(on) and Vgs thresholds match.
