Diodes Incorporated DMN62D2UQ-13

Overview

DMN62D2UQ-13 from Diodes Incorporated is a 60V N-channel enhancement-mode MOSFET in SOT23 package, qualified to AEC-Q101 and PPAP-capable for automotive use. It delivers R_DS(ON) = 2.0 Ω @ V_GS = 5.0 V, 390 mA continuous drain current at +25°C, and features ESD protection, low input capacitance (41 pF), and fast switching (t_D(ON) = 1.5 ns). It is deployed in motor controls, backlighting, and power management circuits.

For engineers reviewing the DMN62D2UQ-13 datasheet, DMN62D2UQ-13 pinout, DMN62D2UQ-13 application, or DMN62D2UQ-13 equivalent, key selection criteria include its AEC-Q101 qualification, low-threshold gate drive compatibility (V_GS(TH) = 0.5–1.0 V), thermal resistance (R_θJA = 197 °C/W), and SOT23 footprint suitability for space-constrained automotive modules.

Technical Context

This MOSFET operates as a low-voltage, logic-level-switched N-channel power switch optimized for automotive subsystems requiring robustness under temperature cycling and transient stress. Its gate threshold voltage range (0.5–1.0 V) enables direct interface with 1.8 V/2.5 V microcontroller GPIOs, while its normalized R_DS(ON) variation remains stable up to +150°C junction temperature.

The device integrates an intrinsic body diode with V_SD = 0.7–1.4 V at 115 mA and exhibits low dynamic parameters: C_iss = 41 pF, C_oss = 5.4 pF, Q_g = 0.8 nC, supporting high-efficiency PWM operation in backlight dimming and motor commutation.

FAQ

Is DMN62D2UQ-13 pin-compatible with other SOT23 N-channel MOSFETs?

No - pinout is fixed as Source-Gate-Drain (1-2-3) per Diodes' SOT23 outline. While many SOT23 MOSFETs share this configuration, compatibility requires verification of R_DS(ON), V_GS(TH), and thermal limits. This part's 1.8 V logic-level drive and 60 V rating are not universal across SOT23 devices.

What is the maximum allowable continuous drain current at +85°C ambient?

At T_A = +85°C, the maximum continuous drain current is 230 mA. This is derived from thermal derating: P_D = 0.6 W (note 5), R_θJA = 197 °C/W, so ΔT = 0.6 × 197 = 118.2°C → T_J = 85 + 118.2 = 203.2°C (exceeds 150°C limit), thus current must be reduced to maintain T_J ≤ 150°C - resulting in I_D ≈ 230 mA.

Does DMN62D2UQ-13 require external gate resistors for automotive PWM operation?

Not strictly required, but recommended. With Q_g = 0.8 nC and typical gate driver rise/fall times <10 ns, a 10–47 Ω series resistor suppresses ringing and reduces EMI in noisy automotive harness environments, especially when driving inductive loads like motors or solenoids.

Can DMN62D2UQ-13 be used in high-side switching configurations?

Yes, but only with appropriate gate drive circuitry. As an N-channel device, it requires a gate voltage ≥ V_DS + V_GS(TH) to fully enhance. In high-side applications, a charge pump or bootstrap circuit is necessary to lift the gate above the drain rail - unlike P-channel alternatives which simplify high-side implementation.
