STD155N3LH6 Equivalent & Substitute Parts

Part Overview

The STD155N3LH6 is an N-Channel MOSFET manufactured by STMicroelectronics, rated for 30V drain-to-source voltage and 80A continuous drain current at 25°C. This device operates in the DeepGATE™ and STripFET™ VI series and is housed in a TO-252 (DPAK) surface mount package. The part is currently Active in product status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are necessary when the original STD155N3LH6 becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design specifications allow for equivalent electrical performance from alternative manufacturers. The substitute parts listed maintain compatibility across critical electrical parameters including voltage rating, current capacity, and thermal characteristics.

Substitute Part Grouping Explanation

Substitution eligibility for the STD155N3LH6 is determined by the following critical parameters:

Electrical Compatibility Requirements:

Drain to Source Voltage (Vdss) must equal or exceed 30V
Continuous Drain Current (Id) must equal or exceed 80A at 25°C
Gate Threshold Voltage (Vgs(th)) must be compatible with 5V and 10V drive voltages
Maximum Gate Voltage (Vgs Max) must accommodate ±20V operation
Operating temperature range must span -55°C to 175°C

Mechanical Compatibility Requirements:

Surface mount technology required
Package must be compatible with TO-252 (DPAK) or equivalent D2PAK footprints
Lead configuration must support 2 leads plus tab topology

Compliance Requirements:

RoHS3 compliance mandatory
Moisture Sensitivity Level (MSL) of 1 (Unlimited) required
REACH Unaffected status required

The substitute parts listed meet these criteria with variations in continuous current capacity (80A to 150A), power dissipation (94W to 178W), and package format (TO-252 DPAK to D2PAK).

Engineering Selection Recommendations

For Direct Replacement (Active Status, TO-252 DPAK Package):

The STD155N3LH6 remains the preferred choice for new designs due to its Active product status and TO-252 (DPAK) package compatibility. No direct equivalent with identical package format is available among the substitute parts listed.

For Alternative Packaging (D2PAK Format):

When D2PAK package format is acceptable, the following parts provide equivalent or superior electrical performance:

PSMN3R4-30BLE,118 (Nexperia USA Inc.): Active product status with 120A continuous current, 3.4mOhm Rds On, and 178W power dissipation. Supplied in Tape & Reel packaging. RoHS3 compliant with unlimited MSL rating.
PSMN2R7-30BL,118 (NXP USA Inc.): Active product status with 100A continuous current, 3mOhm Rds On, and 170W power dissipation. Supplied in Bulk packaging.
PSMN3R4-30BL,118 (NXP USA Inc.): Active product status with 100A continuous current, 3.3mOhm Rds On, and 114W power dissipation. Supplied in Bulk packaging.

For Obsolete or Legacy Designs:

IPB80N03S4L03ATMA1 (Infineon Technologies): Obsolete product status with 80A continuous current matching the main part. PG-TO263-3-2 package. Use only for replacement in existing designs where no alternative is available.
IRL7833STRLPBF (Infineon Technologies): Not For New Designs status with 150A continuous current and D2PAK package. Use only for legacy system maintenance.

Compliance Verification:

All recommended substitute parts maintain RoHS3 compliance, REACH Unaffected status, and unlimited moisture sensitivity rating (MSL 1). Electrical parameters remain within acceptable tolerances for applications designed for the STD155N3LH6.

Frequently Asked Questions (FAQ)

Q: Can PSMN3R4-30BLE,118 directly replace STD155N3LH6 in existing PCB layouts?

A: No. The STD155N3LH6 uses TO-252 (DPAK) package while PSMN3R4-30BLE,118 uses D2PAK package. These packages have different footprints and pin configurations. PCB layout modification is required.

Q: What is the difference between PSMN3R4-30BL,118 and PSMN3R4-30BLE,118?

A: Both parts share identical electrical specifications (30V, 100A/120A respectively, 3.3-3.4mOhm Rds On). The primary difference is packaging: PSMN3R4-30BL,118 is supplied in Bulk format while PSMN3R4-30BLE,118 is supplied in Tape & Reel (TR) format. The "E" suffix indicates Tape & Reel packaging.

Q: Is IPB80N03S4L03ATMA1 suitable for new product designs?

A: No. IPB80N03S4L03ATMA1 carries Obsolete product status. For new designs, select from parts with Active status: PSMN3R4-30BLE,118, PSMN2R7-30BL,118, or PSMN3R4-30BL,118.

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

A: All substitute parts maintain 30V Vdss rating. Continuous drain current ranges from 80A to 150A. Rds On values vary between 3mOhm and 3.8mOhm at 10V gate drive. Power dissipation ranges from 94W to 178W. Gate threshold voltages are slightly lower (2.15V to 2.3V) compared to the main part (2.5V).

Q: Can I use IRL7833STRLPBF as a substitute?

A: IRL7833STRLPBF carries Not For New Designs status and is available only for legacy system maintenance. It provides 150A continuous current and 140W power dissipation in D2PAK package. Use only when replacement of existing components is necessary.

Q: Are all substitute parts RoHS3 compliant?

A: PSMN3R4-30BLE,118 and IRL7833STRLPBF are confirmed RoHS3 compliant. PSMN2R7-30BL,118 and PSMN3R4-30BL,118 do not have RoHS3 compliance explicitly specified in available data. Verify compliance status with supplier before use in RoHS3-restricted applications.

Q: What is the maximum gate voltage for substitute parts?

A: PSMN3R4-30BLE,118, PSMN2R7-30BL,118, and PSMN3R4-30BL,118 support ±20V maximum gate voltage, matching the main part. IPB80N03S4L03ATMA1 supports ±16V maximum gate voltage. IRL7833STRLPBF supports ±20V maximum gate voltage.

Q: Which substitute part offers the lowest on-resistance?

A: PSMN2R7-30BL,118 and STD155N3LH6 both offer 3mOhm Rds On at 10V gate drive, representing the lowest values among the listed parts.
