IXTY2N100P N-Channel 1000V 2A MOSFET Equivalent & Substitute Parts

Part Overview

The IXTY2N100P is an N-Channel MOSFET manufactured by IXYS, rated for 1000V drain-to-source voltage with 2A continuous drain current at 25°C. This device is housed in a TO-252AA surface mount package and is designed for high-voltage switching applications requiring compact form factors. The part is Active in product status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter ranges while maintaining compatibility with the TO-252-3 DPAK package family and surface mount assembly requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IXTY2N100P is determined by the following critical parameters:

Voltage Rating Requirement: Drain-to-source voltage must equal or exceed 1000V to maintain system safety margins and prevent overstress conditions.

Current Rating Requirement: Continuous drain current must meet or exceed 2A at 25°C to support the intended load without thermal derating.

Package Compatibility: The substitute must use the TO-252-3 DPAK surface mount package family to ensure mechanical and electrical compatibility with existing PCB layouts and assembly processes.

On-State Resistance: Rds On characteristics must be compatible with the drive voltage of 10V and support equivalent switching performance.

Temperature Range: Operating temperature range must encompass -55°C to 150°C to maintain functionality across the specified thermal envelope.

Compliance Status: All substitute parts must maintain Active product status and RoHS3 compliance to ensure long-term availability and regulatory conformance.

The STD3NK100Z from STMicroelectronics meets all substitution criteria with equivalent voltage and temperature ratings, compatible package designation, and enhanced current capability.

Engineering Selection Recommendations

Primary Substitute: STD3NK100Z

The STD3NK100Z is a direct functional equivalent for the IXTY2N100P based on the following engineering criteria:

Both devices maintain identical 1000V drain-to-source voltage ratings and -55°C to 150°C operating temperature ranges, ensuring compatibility with system voltage and thermal specifications. Both parts are Active in product status with RoHS3 compliance and unlimited moisture sensitivity rating, confirming long-term availability and regulatory alignment.

The STD3NK100Z provides enhanced electrical performance with 2.5A continuous drain current versus 2A, lower on-state resistance of 6 Ohm at 1.25A compared to 7.5 Ohm at 500mA, and reduced gate charge of 18 nC versus 24.3 nC. These improvements result in lower switching losses and improved thermal efficiency.

Both devices use the TO-252-3 DPAK surface mount package family, ensuring mechanical compatibility with existing PCB layouts and assembly processes. The package designation and pin configuration remain consistent across both parts.

Frequently Asked Questions (FAQ)

Q: Can the STD3NK100Z directly replace the IXTY2N100P in existing designs?

A: Yes. Both devices share identical 1000V voltage ratings, compatible TO-252-3 DPAK surface mount packages, and equivalent operating temperature ranges. The STD3NK100Z provides equal or superior electrical performance across all critical parameters.

Q: What are the key differences between these two MOSFETs?

A: The STD3NK100Z offers higher continuous drain current (2.5A versus 2A), lower on-state resistance (6 Ohm versus 7.5 Ohm), and reduced gate charge (18 nC versus 24.3 nC). These differences result in improved efficiency and reduced switching losses in the substitute part.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the IXTY2N100P and STD3NK100Z are RoHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both maintain unlimited moisture sensitivity rating (MSL 1).

Q: Does the package designation difference (TO-252AA versus DPAK) affect compatibility?

A: No. Both designations refer to the same physical package family: TO-252-3 with 2 leads plus tab in surface mount configuration. The packages are mechanically and electrically interchangeable on standard PCB layouts.

Q: What is the impact of lower gate charge in the STD3NK100Z?

A: Lower gate charge (18 nC versus 24.3 nC) reduces the energy required to switch the device, resulting in lower gate drive losses and improved overall circuit efficiency. This is a performance advantage in the substitute part.

Q: Are there any thermal considerations when substituting these parts?

A: Both devices operate across the identical -55°C to 150°C temperature range. The STD3NK100Z has slightly higher power dissipation rating (90W versus 86W), providing additional thermal margin. Thermal design considerations remain equivalent between the two parts.

Q: What inventory status should be considered for procurement?

A: The IXTY2N100P has 693 pieces in stock, while the STD3NK100Z has 5200 pieces available. The substitute part offers significantly higher inventory availability for immediate procurement needs.
