Diodes Incorporated DMB53D0UV-13

Overview

DMB53D0UV-13 from Diodes Incorporated is a dual-function SOT563-packaged discrete device integrating an N-channel enhancement-mode MOSFET (Q1) and an NPN transistor (Q2) in a single ultra-small surface-mount package. It delivers 50 V V_DSS/V_CBO, 160 mA continuous MOSFET drain current, 100 mA NPN collector current, 4 Ω R_DS(on) at V_GS = 2.5 V, and 1.0 V max gate threshold voltage - enabling low-voltage logic-level switching in space-constrained power management circuits.

For engineers reviewing the DMB53D0UV-13 datasheet, DMB53D0UV-13 pinout, DMB53D0UV-13 application, or DMB53D0UV-13 equivalent, key selection criteria include its dual-device integration for compact load switching, guaranteed 2 kV ESD protection on the MOSFET gate, JEDEC-qualified high-reliability performance, and suitability for automotive-grade derivative parts (Q-suffix variants).

Technical Context

This monolithic dual-die assembly combines two independent semiconductor devices sharing thermal and mechanical substrate but electrically isolated. The MOSFET operates with enhancement-mode behavior, sub-1 V gate threshold, and low input capacitance (25 pF C_iss), while the NPN transistor provides DC current gain (h_FE = 200–450) and low V_CE(SAT) (≤300 mV at I_C = 100 mA).

Both devices share a common SOT563 thermally optimized leadframe with matte tin plating and UL 94V-0 molding compound. Thermal resistance is 500 °C/W (R_θJA), limiting total dissipation to 250 mW at T_A = 25 °C, with operation supported from –55 °C to +150 °C.

Key Specifications

Pinout & Package

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual discrete switching applications.

Compared with DMB53D0UV-13, DMN3026LSD-13 offers lower R_DS(on) but forfeits integrated signal conditioning, while ZXMD63C03X enables push-pull topology but cannot replace the NPN's DC gain for sensor interfacing or bias generation.

FAQ

What is the maximum continuous drain current for the MOSFET portion of DMB53D0UV-13?

The MOSFET (Q1) supports 160 mA continuous drain current at T_A = +25 °C on FR-4 with 2 oz copper and minimum recommended pad layout. At elevated ambient temperatures, derating applies per Figure 9: power dissipation drops linearly to zero at 150 °C ambient.

Can the MOSFET and NPN be used simultaneously without interference?

Yes - the MOSFET and NPN share only the package substrate and thermal path; their electrical terminals are fully isolated. Pin 5/6 is the common drain/collector node, but source (Pin 1) and emitter (Pin 2) are separate, enabling independent control and signal routing.

Is DMB53D0UV-13 qualified for automotive applications?

The base DMB53D0UV-13 is JEDEC-qualified and references AEC-Q101 test standards, but it is not itself AEC-Q101 certified. Automotive-grade versions carry a Q-suffix (e.g., DMB53D0UVQ-13) and are manufactured in IATF 16949-certified facilities with full PPAP support.

What is the significance of the "Green" designation in DMB53D0UV-13?

"Green" refers to Diodes Incorporated's halogen-free, antimony-free, and lead-free material composition compliant with EU RoHS Directive 2011/65/EU. The molding compound meets UL 94V-0 flammability rating and contains no intentionally added hazardous substances.
