DMN65D8LQ-13 N-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The DMN65D8LQ-13 is an N-Channel MOSFET manufactured by Diodes Incorporated, rated for 60V drain-to-source voltage with 310mA continuous drain current at 25°C. The device is housed in a SOT-23-3 surface mount package and is designed for general-purpose switching and amplification applications. The part is currently in active production status with RoHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified based on matching electrical characteristics, thermal performance, and mechanical compatibility. Alternative part numbers within the same product family or from other manufacturers may be required due to inventory availability, supply chain considerations, or specific packaging preferences while maintaining functional equivalence.

Engineering Selection Recommendations

Diodes Incorporated Parametric Equivalents (DMN65 Series):

The DMN65D8L-7, DMN65D8LQ-7, DMN65D8LV-13, and DMN65D8LV-7 are direct parametric equivalents to the DMN65D8LQ-13. All devices share identical electrical specifications across voltage rating, current capacity, on-state resistance, threshold voltage, gate charge, and thermal performance. Selection among these variants is determined by packaging format requirements:

DMN65D8LQ-13 and DMN65D8LQ-7: Tape & Reel packaging for automated assembly
DMN65D8L-7: Cut Tape and Digi-Reel packaging for manual or mixed assembly processes
DMN65D8LV-13 and DMN65D8LV-7: Tape & Reel packaging with alternative internal configuration

All Diodes Incorporated variants maintain RoHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity level (MSL 1).

Manufacturer-Recommended Cross-Reference (Vishay Siliconix):

The 2N7002E-T1-E3 from Vishay Siliconix is a manufacturer-recommended substitute with the following characteristics:

Meets 60V Vdss rating and SOT-23-3 package requirement
Continuous drain current of 240mA is lower than the 310mA specification of the DMN65D8LQ-13
On-state resistance of 3 Ohm matches the DMN65 series at 10V gate voltage
Gate threshold voltage of 2.5V is slightly elevated compared to 2V maximum of the DMN65 series
Gate charge of 0.6 nC is lower, indicating faster switching characteristics
Power dissipation of 350mW is slightly reduced from 370mW
Maintains identical operating temperature range and RoHS3 compliance

The 2N7002E-T1-E3 is suitable for applications where the reduced current rating and slightly higher threshold voltage do not conflict with circuit requirements. This device is available in higher inventory quantities (16818 Pcs).

Selection Basis:

All substitute parts are active production devices with RoHS3 compliance and REACH unaffected status. Selection should be based on packaging format availability, inventory requirements, and specific application current demands. The Diodes Incorporated variants provide direct electrical equivalence, while the Vishay device offers an alternative from a different manufacturer with comparable but not identical performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can DMN65D8L-7 be used as a direct replacement for DMN65D8LQ-13?

A: Yes. The DMN65D8L-7 is a parametric equivalent with identical electrical specifications. The primary difference is packaging format: DMN65D8L-7 is supplied in Cut Tape and Digi-Reel format, while DMN65D8LQ-13 is supplied in Tape & Reel format. Both are surface mount SOT-23-3 devices with the same pin configuration and electrical performance.

Q: What is the difference between DMN65D8LQ-7 and DMN65D8LV-7?

A: Both devices are parametric equivalents with identical electrical specifications and operating characteristics. The difference lies in internal device configuration indicated by the "Q" versus "V" designation. Both are supplied in Tape & Reel packaging and are functionally interchangeable in circuit applications.

Q: Is the 2N7002E-T1-E3 a direct replacement for DMN65D8LQ-13?

A: The 2N7002E-T1-E3 is a manufacturer-recommended cross-reference, not a direct replacement. While both devices share the same 60V rating, SOT-23-3 package, and 3 Ohm on-state resistance, the Vishay device has a lower continuous drain current specification (240mA versus 310mA) and a higher gate threshold voltage (2.5V versus 2V maximum). The 2N7002E-T1-E3 is suitable for applications where these parameter differences are acceptable.

Q: Can I use DMN65D8LV-13 in place of DMN65D8LQ-13 without circuit modification?

A: Yes. The DMN65D8LV-13 is a parametric equivalent with identical electrical specifications, operating temperature range, and power dissipation rating. Both devices are housed in SOT-23-3 packages with identical pin assignments. No circuit modification is required.

Q: What packaging options are available for the DMN65 series?

A: The DMN65 series is available in two packaging formats: Tape & Reel (TR) for automated assembly processes, and Cut Tape with Digi-Reel for manual or mixed assembly operations. All variants use the SOT-23-3 surface mount package with identical electrical performance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed—DMN65D8L-7, DMN65D8LQ-7, DMN65D8LV-13, DMN65D8LV-7, and 2N7002E-T1-E3—are RoHS3 compliant and REACH unaffected. All devices have unlimited moisture sensitivity level (MSL 1).

Q: Which substitute part has the highest inventory availability?

A: The DMN65D8L-7 has the highest inventory with 586,000 pieces in stock, followed by the 2N7002E-T1-E3 with 16,818 pieces. The DMN65D8LQ-13 has 1,254 pieces available.

Q: What is the significance of the gate charge (Qg) difference between DMN65D8LQ-13 and 2N7002E-T1-E3?

A: The DMN65D8LQ-13 has a gate charge of 0.87 nC at 10V, while the 2N7002E-T1-E3 has 0.6 nC at 4.5V. Lower gate charge indicates faster switching speed and reduced gate drive power requirements. The 2N7002E-T1-E3 exhibits faster switching characteristics, which may be advantageous in high-frequency applications but is not a functional requirement for direct substitution.

Q: Can I mix packaging formats in the same assembly?

A: Yes. All substitute parts use the identical SOT-23-3 surface mount package with the same pin configuration and electrical performance. Mixing Tape & Reel and Cut Tape formats in the same assembly is permissible from an electrical and mechanical standpoint; however, assembly process optimization may favor consistent packaging formats.
