DMN31D5UDA-7B

Overview

The DMN31D5UDA-7B is a dual N-channel enhancement mode MOSFET manufactured by Diodes Incorporated. It features a maximum drain-source voltage (VDS) of 30 V and a continuous drain current (ID) of 400 mA at +25°C. The device offers low on-resistance, with RDS(ON) values ranging from 1.5 Ω to 4.5 Ω depending on the gate-source voltage (VGS). Key electrical parameters include a gate threshold voltage (VGS(TH)) of 0.4 V to 1.0 V, total gate charge (Qg) of 0.38 nC, and input capacitance (Ciss) of 22.6 pF. It operates within a temperature range of -55°C to +150°C and is housed in an X2-DFN0806-6 surface-mount package.

Procurement Notes

Verify component authenticity through authorized Diodes Incorporated distributors or official channels. Confirm RoHS compliance and lead-free status against current regulatory standards. Ensure storage conditions adhere to moisture sensitivity level 1 requirements per J-STD-020. Validate ordering suffixes match specific packaging quantities before finalizing procurement orders.

Selection Notes

Select this component for circuits requiring compact dual N-channel MOSFETs with low drive voltage capabilities. Evaluate thermal performance based on the specified junction-to-ambient thermal resistance of 339 °C/W. Consider the low gate threshold voltage for compatibility with low-voltage logic controllers. Verify that the required drain current does not exceed the 400 mA limit under steady-state conditions.

Part Context

This part belongs to the DMN31D5UDA series of dual N-channel enhancement mode MOSFETs. It shares the same core semiconductor structure as other variants in the family but differs in packaging and tape-and-reel specifications. The -7B suffix indicates a specific 10,000-unit tape and reel packaging format used for automated surface-mount assembly processes.

Replacement Considerations

Direct replacements must maintain the 30V VDS rating, dual N-channel topology, and X2-DFN0806-6 footprint. Verify equivalent RDS(ON) and Qg specifications to ensure identical switching performance. Cross-reference pin configurations to confirm D1, S1, G1, D2, S2, G2 alignment.
