ZXMP2120FFTA P-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The ZXMP2120FFTA is an active P-Channel MOSFET manufactured by Diodes Incorporated, rated for 200V drain-to-source voltage with 137mA continuous drain current at 25°C. The device is packaged in SOT-23F surface mount configuration and dissipates a maximum of 1W at ambient temperature. This part is ROHS3 compliant and carries unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter ranges while maintaining compatibility with the application's thermal and spatial constraints. The primary substitute, ZVP2120GTA, offers enhanced current handling and power dissipation in an alternative surface mount package.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ZXMP2120FFTA is determined by the following critical parameters:

Mandatory Matching Parameters:

• FET Type: P-Channel
• Drain to Source Voltage (Vdss): 200V minimum
• Technology: MOSFET (Metal Oxide)
• Operating Temperature Range: -55°C to 150°C minimum
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Performance Parameters (Must Equal or Exceed):

• Continuous Drain Current (Id): 137mA or greater
• Rds On (Max): 28 Ohm or lower at specified conditions
• Vgs(th) (Max): 3.5V or lower
• Power Dissipation: 1W or greater

The ZVP2120GTA qualifies as a direct substitute because it maintains identical voltage ratings, threshold voltage specifications, and gate drive voltage while providing superior current handling (200mA vs. 137mA) and increased power dissipation capability (2W vs. 1W). Both devices share the same base product number (ZVP2120 series) and comply with identical regulatory standards.

Parameter Comparison

Engineering Selection Recommendations

ZXMP2120FFTA Selection Criteria: The ZXMP2120FFTA is the primary choice for applications requiring the SOT-23F package footprint with space constraints. This device is active, ROHS3 compliant, and carries unlimited moisture sensitivity rating, making it suitable for standard manufacturing environments without special handling requirements.

ZVP2120GTA Selection Criteria: The ZVP2120GTA serves as a direct substitute when higher current capacity (200mA vs. 137mA) or increased power dissipation (2W vs. 1W) is required. The SOT-223-3 package provides superior thermal performance and is compatible with applications where the larger footprint is acceptable. Both devices maintain identical voltage ratings, threshold characteristics, and regulatory compliance status.

Regulatory and Compliance Alignment: Both parts are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification. Both maintain unlimited moisture sensitivity level (MSL 1), eliminating special storage or handling requirements. Selection between these parts is determined by application thermal requirements and PCB layout constraints rather than compliance considerations.

Frequently Asked Questions (FAQ)

Q: Can the ZVP2120GTA directly replace the ZXMP2120FFTA in existing designs?

A: The ZVP2120GTA is electrically compatible as a substitute. Both devices share identical voltage ratings (200V Vdss), threshold voltage specifications (3.5V Vgs(th)), and gate drive voltage (10V). The primary design consideration is package footprint: the ZVP2120GTA uses SOT-223-3 (larger) versus the ZXMP2120FFTA SOT-23F (smaller). PCB layout must accommodate the larger package dimensions.

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

A: The primary differences are current rating, power dissipation, and package size. The ZVP2120GTA provides 200mA continuous drain current and 2W power dissipation compared to 137mA and 1W for the ZXMP2120FFTA. The ZVP2120GTA's SOT-223-3 package offers better thermal characteristics than the SOT-23F package. Electrical performance (Rds On, threshold voltage) is equivalent or superior in the ZVP2120GTA.

Q: Are there thermal performance differences between the SOT-23F and SOT-223-3 packages?

A: Yes. The SOT-223-3 package (ZVP2120GTA) provides superior thermal dissipation compared to SOT-23F (ZXMP2120FFTA). This is reflected in the higher maximum power dissipation rating (2W vs. 1W). Applications with higher power dissipation requirements should use the ZVP2120GTA to maintain junction temperature within operating limits.

Q: Do both parts require identical gate drive voltage?

A: Yes. Both the ZXMP2120FFTA and ZVP2120GTA require 10V drive voltage for maximum Rds On specification. Gate drive circuitry designed for one part is directly compatible with the other.

Q: Are moisture sensitivity or storage requirements different between these parts?

A: No. Both parts carry MSL 1 (Unlimited) rating, indicating no special moisture sensitivity precautions are required. Standard manufacturing and storage conditions are acceptable for both devices.

Q: What is the base product number relationship between these parts?

A: The ZXMP2120FFTA uses base product number ZXMP2120, while the ZVP2120GTA uses base product number ZVP2120. Both are part of the same P-Channel MOSFET family from Diodes Incorporated with identical voltage and threshold specifications but different package and current ratings.
