• Gate Threshold Voltage (Vgs(th) Max): 1V @ 250µA
• Gate Charge (Qg Max): 4.3nC @ 4.5V
• Maximum Gate Voltage (Vgs Max): ±8V
• Input Capacitance (Ciss Max): 400pF @ 10V
• Power Dissipation (Max): 800mW
• Operating Temperature Range: -55°C to 150°C

Mechanical Parameters (Must Match):

• Package Type: SOT-23-3 (TO-236-3, SC-59)
• Mounting Type: Surface Mount
• Supplier Device Package: SOT-23-3

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

The DMN2055U-13 and DMN2055U-7 share identical electrical specifications, package configuration, and compliance certifications. Both parts are manufactured by Diodes Incorporated and belong to the same base product family (DMN2055). The difference between these variants is limited to tape and reel configuration (T&R 1 versus T&R 3), which does not affect electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the DMN2055U-13 and DMN2055U-7 are qualified for direct substitution based on complete electrical and mechanical parameter equivalence. Selection between these parts is determined by supply chain availability and tape and reel configuration requirements rather than functional performance differences.

Selection Criteria:

The DMN2055U-13 is suitable for applications requiring T&R 1 tape and reel configuration with current inventory of 10,911 pieces.

The DMN2055U-7 is suitable for applications requiring T&R 3 tape and reel configuration with current inventory of 12,600 pieces.

Both parts maintain Active product status with full RoHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity level (MSL 1), ensuring long-term availability and regulatory compliance for production and end-use applications.

Frequently Asked Questions (FAQ)

Q: Can DMN2055U-7 be used as a direct replacement for DMN2055U-13?

A: Yes. Both parts are electrically and mechanically identical. All electrical parameters including Vdss, Id, Rds On, Vgs(th), gate charge, and operating temperature range are equivalent. Both use the SOT-23-3 surface mount package. Selection is based on tape and reel configuration and inventory availability.

Q: What is the difference between DMN2055U-13 and DMN2055U-7?

A: The only difference is the tape and reel configuration designation (T&R 1 versus T&R 3). This affects packaging and handling during manufacturing but does not impact electrical performance or device functionality.

Q: Are both parts RoHS compliant?

A: Yes. Both DMN2055U-13 and DMN2055U-7 are ROHS3 compliant with REACH unaffected status, meeting environmental and regulatory requirements for commercial and industrial applications.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life under normal storage conditions. No special moisture control measures are required during storage or handling.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Both parts use identical SOT-23-3 package dimensions (TO-236-3, SC-59) and surface mount configuration. PCB footprints, solder reflow profiles, and assembly processes are identical.

Q: What is the operating temperature range for these MOSFETs?

A: Both parts operate from -55°C to 150°C junction temperature (TJ), suitable for industrial and automotive temperature environments.

Q: Are there any gate drive voltage differences between these parts?

A: No. Both parts have identical gate specifications: Vgs(th) Max of 1V @ 250µA, maximum gate voltage of ±8V, and gate charge of 4.3nC @ 4.5V.

Q: What is the maximum continuous drain current for these devices?

A: Both parts are rated for 4.8A continuous drain current at 25°C ambient temperature with on-state resistance of 38mOhm @ 3.6A, 4.5V gate voltage.
