SIL3724-TP MOSFET N/P-Channel 30V Equivalent & Substitute Parts

Part Overview

The SIL3724-TP is a dual-channel MOSFET array integrating both N-channel and P-channel metal oxide semiconductor field effect transistors in a compact SOT-23-6L surface mount package. This component is rated for 30V drain-to-source voltage with continuous drain currents of 5.8A (N-channel) and 4.1A (P-channel) at 25°C, delivering 2W maximum power dissipation across an operating temperature range of -55°C to 150°C.

The SIL3724-TP is classified as obsolete. Locating equivalent substitute parts is necessary to support ongoing production requirements, maintenance operations, and design continuity for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SIL3724-TP is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Drain-to-source voltage rating must equal or exceed 30V
• Continuous drain current ratings must meet or exceed 5.8A (N-channel) and 4.1A (P-channel)
• On-state resistance (RDS On) must not exceed specified maximums to ensure thermal performance
• Power dissipation capability must support 2W operation
• Operating temperature range must encompass -55°C to 150°C

Mechanical Compatibility Requirements:

• Package must be SOT-23-6L surface mount configuration
• Dual N and P-channel configuration must be maintained
• Pin assignment and footprint must be identical

Regulatory Compliance:

• RoHS3 compliance status must be maintained
• ECCN and HTSUS classifications must align with export control requirements

The SIL3724A-TP qualifies as a substitute part based on these criteria. While it exhibits reduced continuous drain current ratings (4.5A N-channel, 3.5A P-channel) and increased on-state resistance values, it maintains the same voltage rating, package configuration, dual-channel topology, operating temperature range, and regulatory compliance status. The SIL3724A-TP is classified as active product status, ensuring ongoing availability and supply chain support.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution:

The SIL3724A-TP is suitable for applications where the reduced continuous drain current ratings (4.5A N-channel, 3.5A P-channel) and increased on-state resistance values do not exceed circuit design margins. This substitute maintains identical voltage ratings, package configuration, and operating temperature specifications. Both parts are RoHS3 compliant and share identical ECCN and HTSUS classifications, ensuring regulatory alignment.

Product Status Consideration:

The SIL3724-TP is obsolete, while the SIL3724A-TP maintains active product status. Selection of the SIL3724A-TP provides access to ongoing manufacturing support, documented supply chain availability, and manufacturer technical resources. The active status of the SIL3724A-TP ensures long-term component availability for production and field replacement requirements.

Compliance and Certification:

Both parts maintain ROHS3 compliance and EAR99 export classification. No additional regulatory review is required when substituting between these components within the same application context.

Frequently Asked Questions (FAQ)

Q: Can the SIL3724A-TP directly replace the SIL3724-TP in existing circuit designs?

A: Direct replacement is possible when circuit design margins accommodate the reduced continuous drain current ratings (4.5A N-channel versus 5.8A, and 3.5A P-channel versus 4.1A) and increased on-state resistance values. The identical voltage rating, package configuration, and operating temperature range ensure mechanical and thermal compatibility. Circuit analysis must confirm that maximum current requirements do not exceed the SIL3724A-TP specifications.

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

A: The primary differences are continuous drain current ratings and on-state resistance specifications. The SIL3724-TP provides higher current capacity (5.8A N-channel, 4.1A P-channel) with lower on-state resistance (30mOhm N-channel, 60mOhm P-channel). The SIL3724A-TP delivers reduced current capacity (4.5A N-channel, 3.5A P-channel) with higher on-state resistance (35mOhm N-channel, 90mOhm P-channel). Both maintain identical voltage ratings, package type, and operating temperature range.

Q: Are there packaging differences between SIL3724-TP and SIL3724A-TP?

A: Both parts use identical SOT-23-6L surface mount packaging. The SIL3724A-TP is supplied in Tape & Reel (TR) format, while the SIL3724-TP packaging format is not specified in available documentation. The physical footprint and pin configuration are identical, enabling direct PCB-level substitution without layout modifications.

Q: What is the significance of the product status difference?

A: The SIL3724-TP is classified as obsolete, indicating discontinued manufacturing and limited availability. The SIL3724A-TP maintains active product status, ensuring ongoing production, documented supply chain support, and manufacturer technical resources. For new designs or long-term production requirements, the active status of the SIL3724A-TP provides supply chain continuity.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the SIL3724-TP and SIL3724A-TP are RoHS3 compliant and share identical ECCN (EAR99) and HTSUS (8541.29.0095) classifications. No additional regulatory review or documentation is required when substituting between these components.

Q: How do the on-state resistance differences affect circuit performance?

A: On-state resistance directly impacts power dissipation and thermal performance. The SIL3724A-TP exhibits higher on-state resistance values (35mOhm N-channel at 3A versus 30mOhm at 5.8A, and 90mOhm P-channel at 3A versus 60mOhm at 4.1A). In applications operating at reduced current levels, this difference may be negligible. In high-current applications, the increased resistance will result in higher power dissipation and junction temperature rise. Thermal analysis is required to confirm acceptable operation within the -55°C to 150°C operating range.

Q: What is the base product number relationship?

A: Both the SIL3724-TP and SIL3724A-TP share the base product number SIL3724. The suffix "-TP" and "-A-TP" designations indicate specific performance variants within the same product family. This relationship confirms functional similarity and design compatibility between the two parts.
