SSM3J15CT(TPL3) Equivalent & Substitute Parts

Part Overview

The SSM3J15CT(TPL3) is a P-Channel MOSFET manufactured by Toshiba Semiconductor and Storage, designed for surface mount applications in the π-MOSVI series. This device operates at 30V drain-to-source voltage with a continuous drain current rating of 100mA at 25°C and a maximum power dissipation of 100mW. The part is currently in active production status and RoHS compliant with unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified when alternative components share the same or superior electrical and mechanical specifications within the defined operating parameters. Substitutes enable design flexibility, support supply chain continuity, and provide options across different manufacturers while maintaining functional compatibility in P-Channel MOSFET applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SSM3J15CT(TPL3) is determined by the following critical parameters:

Primary Substitution Criteria:

• FET Type: P-Channel topology must be maintained
• Drain to Source Voltage (Vdss): Minimum 30V required; higher ratings are acceptable
• Package / Case: SOT-883 form factor compatibility for surface mount applications
• Mounting Type: Surface mount requirement
• RoHS Compliance: Active product status with environmental compliance

Secondary Compatibility Factors:

• Continuous Drain Current (Id): Substitute must support minimum 100mA; higher current ratings provide design margin
• Power Dissipation: Substitute must support minimum 100mW; higher ratings are acceptable
• Gate-Source Voltage (Vgs): Substitute maximum rating must accommodate circuit drive voltage requirements
• Operating Temperature Range: Substitute must support minimum 150°C junction temperature

The PMZ1200UPEYL qualifies as a substitute because it maintains P-Channel topology, meets or exceeds the 30V Vdss requirement, is packaged in SOT-883, supports surface mount assembly, and carries active product status with ROHS3 compliance. The substitute provides enhanced electrical performance with higher continuous drain current (410mA) and improved on-resistance characteristics.

Engineering Selection Recommendations

SSM3J15CT(TPL3) Selection: Select the SSM3J15CT(TPL3) when the application requires the specific electrical characteristics of the Toshiba π-MOSVI series, including the higher gate-source voltage rating (±20V maximum) and lower input capacitance (9.1 pF @ 3V). This part is appropriate for designs with established supply chain relationships with Toshiba Semiconductor and Storage and where the 100mA continuous drain current and 100mW power dissipation are sufficient for the application requirements. RoHS compliance and unlimited MSL rating support standard manufacturing and storage conditions.

PMZ1200UPEYL Selection: Select the PMZ1200UPEYL substitute when the application benefits from enhanced electrical performance, including higher continuous drain current (410mA), improved on-resistance (1.4 Ohm @ 410mA, 4.5V), and extended operating temperature range (-55°C to 150°C). This Nexperia device is appropriate for applications requiring higher current capacity, improved thermal performance (310mW @ Ta, 1.67W @ Tc), and ROHS3 compliance. The substitute maintains SOT-883 package compatibility and surface mount assembly requirements. The lower gate-source voltage maximum (±8V) requires verification that circuit drive voltages remain within this specification.

Both parts carry active product status and unlimited moisture sensitivity level, supporting standard manufacturing and logistics workflows. Selection between these alternatives should be based on current capacity requirements, thermal design margins, and gate drive voltage compatibility with the application circuit.

Frequently Asked Questions (FAQ)

Q: Can the PMZ1200UPEYL directly replace the SSM3J15CT(TPL3) in existing designs?

A: Direct replacement is possible when the application circuit operates within the PMZ1200UPEYL specifications. The substitute maintains P-Channel topology, 30V Vdss rating, and SOT-883 package compatibility. However, the gate-source voltage maximum is reduced from ±20V to ±8V; verify that circuit drive voltages do not exceed ±8V. The higher continuous drain current (410mA) and improved on-resistance provide design margin for most applications.

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

A: The primary differences are continuous drain current (100mA vs. 410mA), on-resistance (12 Ohm @ 10mA, 4V vs. 1.4 Ohm @ 410mA, 4.5V), power dissipation (100mW vs. 310mW @ Ta), gate-source voltage maximum (±20V vs. ±8V), and operating temperature range (150°C vs. -55°C to 150°C). The PMZ1200UPEYL provides higher current capacity and thermal performance; the SSM3J15CT(TPL3) provides higher gate voltage tolerance.

Q: Are both parts available in the same package?

A: Yes. Both the SSM3J15CT(TPL3) and PMZ1200UPEYL are packaged in SOT-883 (SC-101) form factor for surface mount assembly. Package compatibility enables direct footprint substitution on printed circuit boards.

Q: What compliance certifications apply to these parts?

A: The SSM3J15CT(TPL3) carries RoHS compliance certification. The PMZ1200UPEYL carries ROHS3 compliance certification and REACH Unaffected status. Both parts have unlimited moisture sensitivity level (MSL 1) and are classified as active products in current production.

Q: How do the input capacitance values affect circuit performance?

A: The SSM3J15CT(TPL3) has lower input capacitance (9.1 pF @ 3V) compared to the PMZ1200UPEYL (43.2 pF @ 15V). Lower input capacitance reduces gate charge requirements and may improve switching speed in high-frequency applications. Higher input capacitance in the substitute may require increased gate drive current but provides improved noise immunity in some circuit topologies.

Q: What is the significance of the different on-resistance specifications?

A: On-resistance (Rds On) determines power dissipation during conduction. The PMZ1200UPEYL exhibits significantly lower on-resistance (1.4 Ohm @ 410mA, 4.5V) compared to the SSM3J15CT(TPL3) (12 Ohm @ 10mA, 4V). Lower on-resistance reduces conduction losses and heat generation, beneficial for applications with sustained current flow or thermal constraints. The measurement conditions differ between parts; direct comparison requires evaluation at identical current and voltage conditions.

Q: Can the SSM3J15CT(TPL3) be used in applications designed for the PMZ1200UPEYL?

A: The SSM3J15CT(TPL3) can be used as a substitute only when the application current requirements do not exceed 100mA continuous drain current and the circuit design accommodates the higher on-resistance (12 Ohm). The higher gate-source voltage rating (±20V) of the SSM3J15CT(TPL3) provides additional margin for gate drive circuits. Thermal design must account for the lower power dissipation rating (100mW) compared to the PMZ1200UPEYL (310mW @ Ta).
