PMV90ENER N-Channel MOSFET 30V 3A Equivalent & Substitute Parts

Part Overview

The PMV90ENER is an N-Channel MOSFET manufactured by Nexperia USA Inc., rated for 30V drain-to-source voltage with 3A continuous drain current at 25°C. The device is housed in a TO-236AB (SOT-23-3) surface mount package and dissipates a maximum of 460mW. This part is classified as "Not For New Designs," indicating it has reached end-of-life status. Identification of equivalent and substitute parts is necessary to support existing designs, maintenance applications, and inventory management where the original PMV90ENER is no longer available or procurement is constrained.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PMV90ENER is determined by electrical and mechanical compatibility within the N-Channel MOSFET category. The critical parameters that define substitution eligibility are:

Electrical Compatibility Criteria:

• Drain-to-Source Voltage (Vdss) must equal or exceed 30V
• Continuous Drain Current (Id) must meet or exceed 3A at 25°C
• On-State Resistance (Rds On) must not significantly degrade circuit performance
• Gate Threshold Voltage (Vgs(th)) must be compatible with existing drive circuitry
• Operating temperature range must encompass -55°C to 150°C

Mechanical Compatibility Criteria:

• Package type must be TO-236AB, SC-59, or SOT-23-3 (physically and electrically equivalent)
• Surface mount configuration required
• Pin configuration must match TO-236-3 standard

Compliance Criteria:

• RoHS3 compliance required
• Moisture Sensitivity Level (MSL) of 1 or equivalent
• REACH Unaffected status

The SI2304-TP from Micro Commercial Co meets the voltage and package requirements but operates at a reduced continuous drain current of 2.5A, making it suitable for applications where the full 3A rating is not required.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: SI2304-TP

The SI2304-TP is the recommended substitute for the PMV90ENER in applications where the continuous drain current requirement does not exceed 2.5A. Both devices share identical voltage ratings (30V Vdss), compatible package configurations (SOT-23-3), and equivalent compliance certifications (ROHS3, REACH Unaffected, MSL 1). The SI2304-TP maintains active product status, ensuring long-term availability and supply chain stability compared to the PMV90ENER's end-of-life classification.

Application Suitability:

The SI2304-TP is suitable for direct substitution in circuits where:

• Maximum drain current does not exceed 2.5A continuous operation
• Gate drive voltage is compatible with the 3V threshold specification
• Power dissipation budget accommodates the 250mW maximum rating
• Input capacitance increase (240 pF vs. 160 pF) does not adversely affect switching performance

Compliance and Regulatory:

Both the PMV90ENER and SI2304-TP meet ROHS3 compliance requirements and carry REACH Unaffected status, ensuring regulatory compatibility for applications subject to environmental and hazardous substance restrictions. Moisture sensitivity levels are equivalent (MSL 1), permitting identical handling and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the SI2304-TP directly replace the PMV90ENER in all applications?

A: The SI2304-TP is electrically and mechanically compatible with the PMV90ENER in applications where the continuous drain current does not exceed 2.5A. If the circuit requires the full 3A rating of the PMV90ENER, the SI2304-TP is not suitable. Circuit analysis must confirm that peak and continuous current demands remain within the 2.5A specification of the substitute device.

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

A: The primary differences are continuous drain current (3A vs. 2.5A), on-state resistance characteristics (72 mOhm vs. 90 mOhm), gate threshold voltage (2.5V vs. 3V), gate charge (5.5 nC vs. 10 nC), and input capacitance (160 pF vs. 240 pF). These differences may affect switching speed, power dissipation, and gate drive requirements in specific circuit topologies.

Q: Are the packages physically identical?

A: Both devices use the SOT-23-3 package designation (also referenced as TO-236-3 or SC-59). The physical footprint and pin configuration are identical, permitting direct PCB layout compatibility without modification.

Q: What is the significance of the PMV90ENER's "Not For New Designs" status?

A: This classification indicates the PMV90ENER has reached end-of-life and is no longer recommended for new product development. Existing inventory may be available, but long-term supply cannot be guaranteed. The SI2304-TP, classified as "Active," is the appropriate choice for new designs and long-term production requirements.

Q: How do the compliance certifications compare?

A: Both devices are ROHS3 compliant and carry REACH Unaffected status, indicating compliance with European environmental and hazardous substance directives. Moisture sensitivity levels are identical (MSL 1), requiring no changes to component handling, storage, or assembly procedures.

Q: Will the increased gate charge of the SI2304-TP affect circuit performance?

A: The SI2304-TP exhibits higher gate charge (10 nC vs. 5.5 nC) and input capacitance (240 pF vs. 160 pF). In high-frequency switching applications or circuits with limited gate drive current, this increase may result in slower switching transitions and higher gate drive power consumption. Circuit simulation or bench testing is appropriate to confirm performance in timing-critical applications.

Q: What is the impact of the higher gate threshold voltage?

A: The SI2304-TP has a gate threshold voltage of 3V compared to the PMV90ENER's 2.5V. This requires slightly higher gate drive voltage to achieve full on-state conduction. Existing gate drive circuits designed for the PMV90ENER must be evaluated to ensure adequate voltage margin for reliable switching of the SI2304-TP.
