DMP3098LSS-13 Equivalent & Substitute Parts

Part Overview

The DMP3098LSS-13 is a P-Channel MOSFET manufactured by Diodes Incorporated, rated for 30V drain-to-source voltage with 5.3A continuous drain current at 25°C. This device is packaged in an 8-SOIC surface mount configuration and is designed for applications requiring P-channel switching and amplification in low-voltage circuits. The part maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified based on matching electrical specifications and mechanical compatibility within the P-Channel MOSFET category. Substitutes must maintain compatibility with the 8-SOIC package footprint and satisfy the core electrical parameters required for direct board-level replacement.

Frequently Asked Questions (FAQ)

Q: Can the IRF7205TRPBF replace the DMP3098LSS-13 in all applications?

A: The IRF7205TRPBF is electrically and mechanically compatible for direct board-level substitution. However, the continuous drain current rating is 4.6A compared to 5.3A on the primary part. Applications requiring the full 5.3A specification must account for this reduced current capacity. Gate charge is significantly higher at 40nC versus 7.8nC, which affects switching speed and gate drive requirements.

Q: What are the key differences between the STS5P3LLH6 and the DMP3098LSS-13?

A: The STS5P3LLH6 provides superior on-resistance performance at 56mOhm compared to 65mOhm on the primary part. Continuous drain current is 5A versus 5.3A. Gate charge is optimized at 6nC, providing faster switching characteristics. Power dissipation is rated at 2.7W versus 2.5W. All other electrical and mechanical parameters are compatible.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the 8-SOIC package with 0.154" (3.90mm) width. The footprint and pin configuration are identical, enabling direct board-level substitution without layout modifications.

Q: What is the significance of the gate charge (Qg) differences between these parts?

A: Gate charge determines the amount of charge required to switch the MOSFET on and off. The DMP3098LSS-13 has 7.8nC, the STS5P3LLH6 has 6nC, and the IRF7205TRPBF has 40nC. Lower gate charge enables faster switching and reduces gate drive power requirements. Higher gate charge may require stronger gate drive circuits.

Q: Do all three parts meet the same compliance and environmental standards?

A: Yes. All three parts are RoHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are REACH unaffected. All operate across the -55°C to 150°C temperature range. ECCN and HTSUS classifications are identical.

Q: Which substitute should be selected for applications with strict current requirements?

A: For applications requiring the full 5.3A specification, the STS5P3LLH6 at 5A is the closest match. The IRF7205TRPBF at 4.6A should only be selected for applications where the reduced current capacity is acceptable.

Q: How do the on-resistance characteristics affect thermal performance?

A: Lower on-resistance reduces power dissipation during conduction. The STS5P3LLH6 at 56mOhm generates less heat than the DMP3098LSS-13 at 65mOhm. The IRF7205TRPBF at 70mOhm generates more heat. In high-current or high-frequency applications, on-resistance differences directly impact thermal management requirements.
