• Continuous Drain Current (Id): Minimum 5.8A at 25°C (within 97% of primary part specification)
• On-Resistance (Rds On): Maximum 32 mOhm at specified gate voltage and current
• Gate Threshold Voltage (Vgs(th)): Maximum 2.4V at 250µA
• Package Form Factor: 8-SOIC surface mount configuration
• Compliance: ROHS3 compliant, MSL 1 rating

Electrical Operating Range:

• Gate Voltage (Vgs): ±20V maximum
• Input Capacitance (Ciss): Measured at specified drain-source voltage
• Power Dissipation: Rated for thermal management in target applications

The DMP3037LSS-13 from Diodes Incorporated satisfies all critical substitution criteria and maintains functional equivalence within the specified electrical and thermal operating envelope.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: STS6P3LLH6

The STS6P3LLH6 is the specified component with Active product status and full availability (6367 pcs in stock). This part is manufactured by STMicroelectronics and carries ROHS3 compliance with unlimited moisture sensitivity rating. The device is suitable for direct selection in new designs and production applications.

Substitute Part: DMP3037LSS-13

The DMP3037LSS-13 from Diodes Incorporated is an equivalent substitute with Active product status and significantly higher inventory availability (45300 pcs in stock). This part maintains identical voltage rating (30V Vdss) and package configuration (8-SOIC). The continuous drain current specification of 5.8A is within acceptable tolerance of the primary part's 6A rating.

Compliance and Certification:

Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both devices carry MSL 1 (unlimited) moisture sensitivity rating, indicating no special handling requirements during storage or assembly.

Selection Criteria:

• Use STS6P3LLH6 when STMicroelectronics sourcing is required or when the lower gate charge specification (12 nC @ 4.5V) is advantageous for switching speed optimization.
• Use DMP3037LSS-13 when supply chain flexibility is required, when higher inventory availability is beneficial, or when the extended operating temperature range (-55°C to 150°C) is specified.

Both parts are suitable for direct pin-for-pin substitution in 8-SOIC surface mount applications with 30V P-Channel MOSFET requirements.

Frequently Asked Questions (FAQ)

Q: Can the DMP3037LSS-13 be used as a direct replacement for the STS6P3LLH6?

A: Yes. Both devices are P-Channel MOSFETs with identical 30V drain-to-source voltage rating and 8-SOIC package configuration. The continuous drain current of 5.8A (DMP3037LSS-13) is within acceptable tolerance of the 6A specification (STS6P3LLH6). On-resistance characteristics are comparable at specified gate voltages. Both parts are ROHS3 compliant with unlimited moisture sensitivity rating.

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

A: The DMP3037LSS-13 exhibits higher gate threshold voltage (2.4V vs. 1V), higher gate charge (19.3 nC @ 10V vs. 12 nC @ 4.5V), and lower input capacitance (931 pF @ 15V vs. 1450 pF @ 24V). The DMP3037LSS-13 has lower maximum power dissipation (1.2W vs. 2.7W) and an extended operating temperature range (-55°C to 150°C vs. 150°C maximum). These differences do not prevent functional substitution in standard P-Channel MOSFET applications.

Q: Are the packages physically identical?

A: Yes. Both parts use the 8-SOIC package with 0.154" (3.90mm) width specification. Pin-for-pin substitution is supported without PCB layout modification.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging for the STS6P3LLH6 is supplied on continuous tape for automated assembly equipment. Cut Tape (CT) and Digi-Reel® packaging for the DMP3037LSS-13 provides flexibility for both automated and manual assembly processes. Both packaging formats contain identical electronic components and are suitable for surface mount assembly.

Q: Are both parts suitable for new design applications?

A: Yes. Both the STS6P3LLH6 and DMP3037LSS-13 carry Active product status, indicating ongoing manufacturer support and availability. Both parts are ROHS3 compliant and suitable for new design implementation.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both carry MSL 1 (unlimited) moisture sensitivity rating, requiring no special handling during storage or assembly operations.

Q: Which part should be selected for switching speed optimization?

A: The STS6P3LLH6 exhibits lower gate charge (12 nC @ 4.5V) compared to the DMP3037LSS-13 (19.3 nC @ 10V), resulting in faster switching transitions. Select the STS6P3LLH6 when gate charge minimization is a design requirement.

Q: Which part offers better thermal performance?

A: The DMP3037LSS-13 has lower maximum power dissipation (1.2W vs. 2.7W), indicating superior thermal efficiency under specified operating conditions. The DMP3037LSS-13 also provides an extended operating temperature range (-55°C to 150°C), offering greater thermal margin in temperature-sensitive applications.
