Product details

Overview

DMN90H2D2HCTI from Diodes Incorporated is a 900 V, 6 A N-channel enhancement-mode MOSFET in ITO-220AB package, featuring 2.2 Ω R_DS(ON) at V_GS = 10 V and 360 mJ avalanche energy rating. It serves as a high-voltage switching element in offline power stages, delivering low conduction loss and robust unclamped inductive switching capability for industrial DC-DC converters.

For engineers reviewing the DMN90H2D2HCTI datasheet, DMN90H2D2HCTI pinout, DMN90H2D2HCTI application, or DMN90H2D2HCTI equivalent, key selection criteria include its 900 V BVDSS rating, 2.2 Ω on-resistance at 10 V gate drive, 24 A pulsed drain current, 1487 pF input capacitance, and ITO-220AB thermal performance with 3.6 °C/W R_θJC.

Technical Context

This MOSFET employs a planar silicon process optimized for high-voltage ruggedness and fast switching. Its gate threshold voltage (3–5 V) enables compatibility with standard 10 V gate drivers, while the low Crss (1 pF) and Qgd (6.1 nC) support reduced Miller-induced turn-off delay in hard-switched topologies.

The device integrates an intrinsic body diode with 607 ns reverse recovery time and 8.1 µC Q_RR, suitable for freewheeling in flyback and resonant converters. Thermal design leverages the ITO-220AB package's low junction-to-case resistance (3.6 °C/W) for reliable operation up to +150 °C junction temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
BVDSS	900 V - Withstands full mains-referenced DC bus voltages in 380–400 VAC offline systems without breakdown.
RDS(ON)	2.2 Ω @ VGS = 10 V - Delivers ≤1.2 W conduction loss at 6 A continuous drain current under typical gate drive conditions.
ID (TC = 25°C)	6 A - Supports continuous output power up to ~25 W in TO-220-class heatsink-limited designs.
EAS	360 mJ - Sustains single-pulse inductive energy transients common in motor drive and relay snubbing applications.
Ciss	1487 pF - Determines total gate charge requirement (20.3 nC), influencing driver strength and switching speed trade-offs.
tRR / QRR	607 ns / 8.1 µC - Defines body diode recovery behavior critical for ZVS/ZCS soft-switching implementation and EMI control.
RθJC	3.6 °C/W - Enables direct mounting to heatsinks for thermal management in space-constrained industrial enclosures.

Pinout & Package

Source	Reference node for gate drive and current sensing	Low-impedance return path; used for shunt-based current monitoring and gate driver reference in half-bridge configurations.
Gate	Control terminal for channel modulation	High-impedance input requiring <6.1 nC charge for full turn-on; sensitive to ringing due to 4.7 Ω internal gate resistance.

Key Features

Feature	Design Value
High BVDSS rating	900 V withstand capability ensures margin against line surges and reflected spikes in 400 VAC-input SMPS.
Low input capacitance	1487 pF Ciss reduces gate drive power and improves switching efficiency in high-frequency (>100 kHz) converters.
Robust avalanche capability	360 mJ EAS allows safe operation during transient overloads without external snubbers in motor control H-bridges.
Thermally optimized package	ITO-220AB delivers 3.6 °C/W RθJC - 25% lower than standard TO-220 - enabling higher power density in convection-cooled designs.
Green and RoHS-compliant	Halogen- and antimony-free construction (<900 ppm Br/Cl, <1000 ppm Sb) meets automotive and industrial environmental compliance mandates.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage N-channel MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP9NK90ZFP	900 V, 8.5 A, 1.4 Ω RDS(ON), TO-220FP package, no specified EAS rating	Lacks documented avalanche energy spec; higher ID but larger RDS(ON) drift over temperature	Preferable where peak current >6 A is required and avalanche stress is minimal.
IXTP90N10P	1000 V, 90 A, 0.1 Ω RDS(ON), TO-220 package, 1200 mJ EAS	Higher cost, oversized for 6 A use case; excessive capacitance (3200 pF) limits switching frequency	Suitable only when future-proofing for >10 A loads or extreme surge immunity is mandatory.

Compared with STP9NK90ZFP and IXTP90N10P, DMN90H2D2HCTI offers optimal balance of 900 V rating, 6 A capability, 2.2 Ω on-resistance, and verified 360 mJ avalanche robustness - making it more thermally efficient and better suited for compact, convection-cooled 25–30 W industrial power supplies.

FAQ

Is DMN90H2D2HCTI still in active production?

No - Diodes Incorporated has officially discontinued DMN90H2D2HCTI (marked "OBSOLETE – PART DISCONTINUED" in DS38826 Rev. 6-4). Aetrix Electronics maintains limited legacy stock with full traceability and offers engineering support for last-time buy and obsolescence mitigation planning.

Can DMN90H2D2HCTI be used in AEC-Q101 qualified designs?

No - this part is not AEC-Q101 qualified. The datasheet explicitly states that automotive-grade versions require separate qualification (AEC-Q100/101/104/200), PPAP capability, and IATF 16949 manufacturing - none of which apply to DMN90H2D2HCTI.

What is the maximum recommended gate resistor value for reliable switching?

Based on Qg = 20.3 nC and tD(OFF) = 51 ns with Rg = 25 Ω in test conditions, a gate resistor between 10 Ω and 33 Ω is recommended to limit peak gate current while maintaining <100 ns turn-off delay in 65–100 kHz applications.

Does the ITO-220AB package require insulating hardware when mounted to a heatsink?

Yes - the drain is electrically connected to the metal tab. An insulating washer (e.g., mica or silicone pad) and shoulder washer must be used unless the heatsink is intentionally tied to the drain potential, as confirmed by system-level isolation analysis.
