Diodes Incorporated DMN22M5UFG-13

Overview

DMN22M5UFG-13 from Diodes Incorporated is a 20V N-channel enhancement-mode MOSFET in PowerDI3333-8 package, optimized for high-efficiency power management with R_DS(ON) = 1.5 mΩ (typ) at V_GS = 4.5V, 27A continuous drain current at T_C = +25°C, and 100% production-tested UIS robustness. It serves as a primary synchronous rectifier or main switch in compact DC-DC converters.

For engineers reviewing the DMN22M5UFG-13 datasheet, DMN22M5UFG-13 pinout, DMN22M5UFG-13 application, or DMN22M5UFG-13 equivalent, key selection criteria include low-voltage gate drive compatibility (2.5V–4.5V), thermal performance in high-density layouts, body diode recovery behavior in hard-switched topologies, and RoHS/Green compliance for consumer and industrial end products.

Technical Context

This MOSFET employs a trench-gate silicon process to achieve ultra-low on-resistance while maintaining fast switching characteristics: t_D(ON) = 8.1 ns, Q_g = 53 nC (at V_GS = 4.5V), and C_iss = 3926 pF. Its 1.7°C/W junction-to-case thermal resistance enables direct thermal coupling to PCB copper planes.

The device features a fully rated body diode with t_RR = 23.3 ns and Q_RR = 11.5 nC under IF = 13.5A / di/dt = 100 A/μs conditions, supporting efficient synchronous rectification and bidirectional current handling in buck and boost stages.

FAQ

What is the maximum safe operating temperature for DMN22M5UFG-13 in continuous conduction mode?

The device supports junction temperatures from –55°C to +150°C. Under continuous DC operation on a 2 oz copper FR-4 board with thermal bias, its maximum steady-state power dissipation is 2.2 W (R_θJA = 56°C/W), limiting T_J to ≤150°C at T_A = +70°C. Derating is required above 70°C ambient.

Does DMN22M5UFG-13 require a gate resistor for EMI suppression in 1 MHz switching applications?

Yes - although its intrinsic R_g is only 0.9 Ω, a 1.5–2.2 Ω series gate resistor is recommended to damp ringing caused by PCB trace inductance and minimize dv/dt-induced noise in adjacent signal layers. This value balances switching speed (t_F ≈ 45 ns) and EMI compliance per CISPR 32 Class B.

Can DMN22M5UFG-13 be used in parallel configurations to increase current capacity?

Yes - its positive temperature coefficient of R_DS(ON) (see Figure 5) ensures inherent current sharing. Layout must mirror source/drain routing lengths and use separate gate resistors per device to prevent oscillation. Parallel operation is validated up to 4 devices in Diodes' AN-2001 application note.

Is the PowerDI3333-8 package compatible with standard reflow profiles for lead-free assembly?

Yes - the device is qualified for J-STD-020 Level 1 moisture sensitivity and withstands peak reflow temperatures up to 260°C for 30 seconds. The matte tin finish on the copper leadframe ensures reliable solder joint formation using SAC305 paste and standard ramp-soak-reflow profiles.
