DMN5L06-7 Equivalent & Substitute Parts

Part Overview

The DMN5L06-7 is an N-Channel MOSFET manufactured by Diodes Incorporated, rated for 50V drain-to-source voltage with 280mA continuous drain current in a surface mount SOT-23-3 package. This device is classified as obsolete, necessitating identification of equivalent and substitute components for ongoing production and design requirements. Substitute parts must maintain electrical compatibility across voltage ratings, current handling, and thermal characteristics while accommodating the SOT-23-3 package form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DMN5L06-7 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Drain-to-Source Voltage (Vdss) must equal or exceed 50V
• Continuous Drain Current (Id) must meet or exceed 280mA at 25°C
• Power Dissipation (Max) must support 350mW thermal envelope
• Gate-Source Voltage (Vgs) range must accommodate ±20V
• Operating temperature range must span -55°C to 150°C minimum

Mechanical Compatibility Requirements:

• Mounting type: Surface Mount
• Package: SOT-23-3 (TO-236-3, SC-59 equivalent)
• Lead configuration: 3-pin

Compliance Requirements:

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts are grouped into two categories: direct electrical equivalents (matching or exceeding all primary electrical specifications) and functional alternatives (meeting minimum voltage and current requirements with acceptable thermal performance).

Engineering Selection Recommendations

Primary Substitute: BVSS138LT1G (onsemi)

The BVSS138LT1G is an active product offering direct electrical compatibility with the DMN5L06-7. Both devices share identical Vdss (50V), matching Vgs(th) threshold characteristics, and equivalent input capacitance. The BVSS138LT1G maintains the same SOT-23-3 package configuration and operating temperature range (-55°C to 150°C). RoHS3 compliance and unlimited moisture sensitivity level (MSL 1) align with the original specification. The reduced power dissipation rating (225mW vs. 350mW) represents a conservative thermal margin. Active product status ensures long-term availability and supply chain continuity.

Secondary Substitute: BSS138L (onsemi)

The BSS138L provides functional equivalence with identical voltage rating (50V) and matching package form factor. Continuous drain current specification (200mA) falls below the original 280mA rating but remains suitable for applications not requiring full current capacity. Power dissipation (350mW) matches the original specification exactly. Active product status and RoHS3 compliance support production continuity. Operating temperature range (-55°C to 150°C) is identical to the DMN5L06-7.

Tertiary Substitute: BSS138 (Good-Ark Semiconductor)

The BSS138 maintains 50V Vdss rating and SOT-23-3 package compatibility. Continuous drain current (220mA) is lower than the original specification. Power dissipation (430mW) exceeds the original 350mW rating, providing thermal headroom. Extended operating temperature range (-55°C to 175°C) offers additional margin. Active product status and high inventory availability (185,400 units) support production requirements. RoHS3 compliance is confirmed.

Alternative Substitute: 2N7002P,215 (Nexperia USA Inc.)

The 2N7002P,215 offers enhanced electrical performance with higher Vdss (60V) and superior continuous drain current (360mA). Rds On characteristics are improved (1.6Ohm @ 500mA, 10V). Package compatibility is maintained through TO-236AB designation, which is mechanically equivalent to SOT-23-3. Power dissipation (350mW) matches the original specification. Product status is "Not For New Designs," limiting suitability for new development but acceptable for legacy system support. RoHS3 compliance and automotive qualification (AEC-Q100) provide additional assurance.

Frequently Asked Questions (FAQ)

Q: Can the BVSS138LT1G directly replace the DMN5L06-7 in existing designs?

A: Yes. The BVSS138LT1G maintains identical Vdss (50V), matching Vgs(th) threshold voltage, and equivalent input capacitance. Both devices use the SOT-23-3 package with identical pin configuration. Operating temperature range (-55°C to 150°C) is identical. The reduced power dissipation rating (225mW vs. 350mW) represents a conservative thermal margin suitable for direct substitution.

Q: Why is the continuous drain current lower on BSS138L and BSS138 compared to the DMN5L06-7?

A: The BSS138L and BSS138 are rated for 200mA and 220mA respectively, compared to the DMN5L06-7 specification of 280mA. These devices are suitable for applications operating below their rated current limits. Circuit design must verify that actual operating current does not exceed the substitute device rating.

Q: Is the 2N7002P,215 suitable for new production designs?

A: The 2N7002P,215 carries a "Not For New Designs" product status designation. While electrically compatible and available in quantity, this status indicates the manufacturer does not recommend its use in new development. The BVSS138LT1G or BSS138L are preferred for new designs due to active product status.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (BVSS138LT1G, BSS138L, BSS138, and 2N7002P,215) carry RoHS3 Compliant certification, matching the original DMN5L06-7 specification.

Q: What is the difference between SOT-23-3 and TO-236AB packaging?

A: SOT-23-3 and TO-236AB are mechanically equivalent package designations for the same physical form factor. Both refer to a 3-pin surface mount package with identical lead spacing and dimensions. The 2N7002P,215 uses the TO-236AB designation but is physically compatible with SOT-23-3 footprints.

Q: Can I use the BSS138 in place of the DMN5L06-7 if my circuit operates below 220mA?

A: Yes, provided circuit operating current does not exceed 220mA continuous drain current. The BSS138 maintains identical 50V Vdss rating, matching SOT-23-3 package, and RoHS3 compliance. Higher power dissipation rating (430mW vs. 350mW) provides thermal margin. Verify gate drive voltage compatibility with your circuit design.

Q: What is the significance of the Vgs(th) threshold voltage differences between substitute parts?

A: Vgs(th) determines the gate voltage required to turn the MOSFET on. The DMN5L06-7 specifies 1.2V @ 250µA, while BVSS138LT1G and BSS138L specify 1.5V @ 1mA. These differences are within normal device variation and do not prevent substitution. Circuit gate drive voltage must exceed the substitute device threshold to ensure proper operation.

Q: Is inventory availability a factor in selecting a substitute?

A: Inventory levels are provided for reference but do not determine electrical substitutability. The BVSS138LT1G (63,400 units), BSS138L (17,760 units), and BSS138 (185,400 units) all maintain adequate stock. Inventory should be verified with your component supplier for current availability.
