FDMA0104 N-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The FDMA0104 is an N-Channel MOSFET manufactured by onsemi, rated for 20V drain-to-source voltage with 9.4A continuous drain current at 25°C. This device is housed in a 6-MicroFET (2x2) surface mount package and is part of the PowerTrench® series. The FDMA0104 is classified as obsolete, making identification of equivalent and substitute parts necessary for ongoing design support, production continuity, and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FDMA0104 is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Drain-to-Source Voltage (Vdss) must equal or exceed 20V
• Continuous Drain Current (Id) must equal or exceed 9.4A at 25°C
• On-State Resistance (Rds On) must not exceed 14.5mOhm at the specified gate voltage and current
• Gate Threshold Voltage (Vgs(th)) must be compatible with existing gate drive circuits
• Gate Charge (Qg) and Input Capacitance (Ciss) must be within acceptable switching performance parameters
• Operating temperature range must encompass -55°C to 150°C (TJ)

Mechanical Compatibility Criteria:

• Surface mount package configuration
• Pin count and footprint compatibility
• Moisture sensitivity level MSL 1 or better

The PMPB10XNE,115 from Nexperia USA Inc. meets these substitution criteria with matching voltage ratings, comparable current ratings, and compatible on-state resistance specifications.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The FDMA0104 is classified as obsolete. The PMPB10XNE,115 is classified as active, ensuring continued availability and manufacturing support from Nexperia USA Inc.

Compliance and Certifications: Both devices share identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS code (8541.29.0095). Both devices maintain MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture handling requirements.

Electrical Performance: The PMPB10XNE,115 delivers equivalent electrical performance within the specified operating envelope. Continuous drain current is rated at 9A compared to 9.4A for the FDMA0104, representing a 4.3% reduction. On-state resistance is 14mOhm at 9A and 4.5V gate voltage, compared to 14.5mOhm for the FDMA0104, providing superior conductivity. Gate threshold voltage is lower (0.9V versus 1V), improving gate drive efficiency.

Package Considerations: The FDMA0104 uses a 6-WDFN package while the PMPB10XNE,115 uses a 6-UDFN package. Both are 6-pin surface mount packages with exposed pads. Physical footprint compatibility must be verified against specific PCB layout requirements, as WDFN and UDFN packages may have dimensional differences.

Gate Charge and Capacitance: The PMPB10XNE,115 exhibits higher gate charge (34nC versus 17.5nC) and input capacitance (2175pF versus 1680pF). These parameters affect switching speed and gate drive circuit requirements. Applications with tight switching frequency constraints or limited gate drive current capacity must account for these differences.

Frequently Asked Questions (FAQ)

Q: Can the PMPB10XNE,115 directly replace the FDMA0104 in existing designs?

A: Electrical substitution is valid based on voltage rating, current rating, and on-state resistance specifications. However, package footprint differences between 6-WDFN and 6-UDFN require PCB layout verification. Gate charge and input capacitance differences may require gate drive circuit evaluation for applications with marginal drive capability.

Q: What is the significance of the 4.3% reduction in continuous drain current from 9.4A to 9A?

A: The PMPB10XNE,115 is rated for 9A continuous drain current at 25°C ambient temperature, compared to 9.4A for the FDMA0104. Applications operating at or near the 9.4A limit must verify that the 9A rating of the substitute part provides adequate margin for the intended load current.

Q: How do the gate charge differences affect circuit performance?

A: The PMPB10XNE,115 requires approximately twice the gate charge (34nC versus 17.5nC) for switching transitions. Gate drive circuits must supply sufficient current to charge the gate within the required switching time. Applications with current-limited gate drive sources must evaluate whether the higher gate charge impacts switching frequency or introduces unacceptable switching losses.

Q: Are there package footprint compatibility issues between 6-WDFN and 6-UDFN?

A: Both packages are 6-pin surface mount configurations with exposed pads. However, WDFN (Wafer-level Dual Flat No-lead) and UDFN (Ultra-thin Dual Flat No-lead) packages may have different lead pitch, body dimensions, or pad sizes. PCB layout files must be reviewed to confirm mechanical compatibility before design release.

Q: What is the impact of lower gate threshold voltage (0.9V versus 1V)?

A: The lower gate threshold voltage of the PMPB10XNE,115 (0.9V) compared to the FDMA0104 (1V) indicates faster turn-on at lower gate voltages. This improves gate drive efficiency and may reduce switching losses in applications with fixed gate drive voltage sources.

Q: Are both devices compliant with the same regulatory standards?

A: Yes. Both the FDMA0104 and PMPB10XNE,115 share identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS code (8541.29.0095). Both devices maintain MSL 1 moisture sensitivity rating, eliminating special handling requirements.

Q: Why is the FDMA0104 obsolete while the PMPB10XNE,115 is active?

A: The FDMA0104 has reached end-of-life status with onsemi. The PMPB10XNE,115 from Nexperia USA Inc. remains in active production, ensuring continued component availability, manufacturing support, and technical documentation updates.
