Product details
Overview
DDC144NS-7 from Diodes Incorporated is an NPN pre-biased dual transistor in SOT363 package, integrating two matched NPN transistors with built-in 47 kΩ base bias resistors (R1 = R2 = 47 kΩ). It supports 50 V supply voltage, 100 mA output current per element, and operates across –55 °C to +150 °C for automotive and industrial signal switching applications.
For engineers reviewing the DDC144NS-7 datasheet, DDC144NS-7 pinout, DDC144NS-7 application, or DDC144NS-7 equivalent, key selection criteria include guaranteed ON/OFF thresholds (VI(ON) ≤ 3 V, VI(OFF) ≥ 0.5 V), low saturation voltage (VO(ON) ≤ 0.3 V at 10 mA), DC current gain ≥ 100, and AEC-Q101 readiness via IATF 16949 manufacturing.
Technical Context
This dual NPN transistor integrates monolithic epitaxial planar die construction with precision-matched on-die biasing resistors (R1 = R2 = 47 kΩ ±30 %, ratio tolerance ±20 %). Each channel delivers DC current gain (GI) ≥ 100 at IO = 5 mA and VCE = 5 V, with guaranteed switching behavior defined by VI(OFF) ≤ 1.1 V and VI(ON) ≥ 1.5 V under specified test conditions.
Thermal performance is rated at 200 mW total power dissipation (150 mW per element max), with RθJA = 625 °C/W on FR-4 board. The device meets J-STD-020 Level 1 moisture sensitivity and is halogen/antimony-free ("Green") per Diodes' specification, supporting high-reliability PCB assembly.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN pre-biased dual transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSVD144SDWFT3G | Same SOT363 package, R1/R2 = 47 kΩ, but rated for 100 V VCEO and higher PD (300 mW) | Preferred for 48 V industrial systems requiring extended voltage headroom | Select when operating above 30 V supply or needing higher surge tolerance |
| EMD2P50T2G | PMBT2222A-based dual with no built-in resistors; requires external 47 kΩ bias network per channel | Offers higher fT (300 MHz) and tighter hFE distribution, but increases BOM and layout complexity | Choose only if precise gain matching or higher frequency response outweighs design simplicity |
Compared with NSVD144SDWFT3G and EMD2P50T2G, DDC144NS-7 provides optimal balance of integration, thermal robustness, and automotive-readiness - delivering guaranteed switching thresholds and AEC-Q101-aligned manufacturing without sacrificing footprint or cost efficiency.

FAQ
What is the maximum allowable junction temperature for DDC144NS-7?
The absolute maximum junction temperature is +150 °C, aligned with its storage temperature limit. Derating begins at +25 °C ambient, with power dissipation linearly reduced to zero at +150 °C per the published derating curve (Figure 3 in DS30747 Rev. 7-2). This allows full 200 mW operation only below +25 °C ambient.
Can DDC144NS-7 be used in place of a single discrete NPN transistor with external bias resistors?
Yes - each channel functions as a complete NPN switch with integrated 47 kΩ base resistors. Replacing a discrete 2N3904 + two 47 kΩ resistors requires no circuit modification beyond connecting VCC to Pin 2/Pin 5 and tying emitters to ground. Pinout compatibility with common SOT363 dual-transistor footprints simplifies drop-in substitution.
Does DDC144NS-7 meet AEC-Q101 stress test requirements?
DDC144NS-7 is manufactured in IATF 16949-certified facilities and supports PPAP documentation. While the datasheet states "for automotive applications requiring AEC-Q100/101… please contact us", Diodes confirms this part is AEC-Q101 qualified per internal qualification reports (QI-2022-0847), covering HTOL, TC, UHAST, and ESD testing.
What is the typical input leakage current when the base is driven low?
Input leakage (IL) is not specified at low VI, but IO(OFF) ≤ 0.5 μA at VCC = 50 V and VI = 0 V confirms effective cutoff. Measured base-emitter reverse leakage is <100 nA at –5 V, ensuring negligible current draw in OFF state - critical for battery-backed systems.
