DMN52D0UQ-13 Equivalent & Substitute Parts

Part Overview

The DMN52D0UQ-13 is an N-Channel MOSFET manufactured by Diodes Incorporated, designed for surface mount applications in the SOT-23-3 package. This device operates at a drain-source voltage (Vdss) of 50 V with a continuous drain current rating of 400 mA at 25°C and a maximum power dissipation of 500 mW. The part is qualified to AEC-Q101 automotive standards and maintains active product status. Substitute parts are identified to provide design flexibility when the primary part number is unavailable or when inventory constraints require alternative sourcing options.

• Gate Threshold Voltage (Vgs(th) Max): 1 V @ 250 µA
• Gate Charge (Qg Max): 1.5 nC @ 10 V
• Input Capacitance (Ciss Max): 39 pF @ 25 V
• Maximum Gate Voltage (Vgs): ±12 V
• Power Dissipation (Max): 500 mW
• Operating Temperature Range: -55°C to 150°C

Mechanical Equivalence Criteria:

• Package Type: SOT-23-3 (TO-236-3, SC-59)
• Mounting Type: Surface Mount
• Packaging Format: Tape & Reel (TR)

Compliance Equivalence Criteria:

• RoHS3 Compliance
• Moisture Sensitivity Level (MSL): 1
• REACH Status: REACH Unaffected
