Product details
Overview
DDC115EU-7-F from Diodes Incorporated is an NPN pre-biased dual small-signal transistor in SOT363 package, featuring integrated 100kΩ–100kΩ bias resistors (R1 = R2), 50V VCEO, 20mA continuous output current, and 200mW power dissipation. It functions as a dual-channel logic-level switch in compact space-constrained digital interface circuits.
For engineers reviewing the DDC115EU-7-F datasheet, DDC115EU-7-F pinout, DDC115EU-7-F application, or DDC115EU-7-F equivalent, key selection criteria include input voltage thresholds (VI(on) = 3.0V @ IO = 1mA), low saturation voltage (VCE(sat) ≤ 0.3V), AEC-Q101 qualification for automotive use, and dual-element thermal derating behavior per element.
Technical Context
This dual NPN transistor integrates matched 100kΩ base bias resistors on both channels, enabling direct TTL/CMOS-compatible switching without external resistor networks. Each channel operates independently with isolated emitter terminals and shared collector supply path via internal layout.
It supports rail-to-rail input operation up to +40V and withstands −10V reverse input, with guaranteed DC current gain (GI) of 82 at VO = 5V and IO = 5mA. Thermal derating follows 625°C/W junction-to-ambient resistance on FR-4 PCB with minimum pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50V - Maximum collector-emitter voltage before breakdown; enables use in 24V industrial control rails. |
| IO (max) | 20mA - Continuous output current per channel; suitable for driving LED indicators or small logic loads. |
| R1 / R2 | 100kΩ / 100kΩ - Matched internal base bias resistors; eliminates need for two external resistors per channel. |
| VI(on) | 3.0V @ IO = 1mA - Input turn-on threshold compatible with 3.3V logic families. |
| VCE(sat) | ≤0.3V @ IC/IB = 10mA/0.5mA - Low saturation loss preserves signal margin in level-shifting applications. |
| PD | 200mW - Total package power limit; 150mW max per element ensures safe dual-channel operation. |
| fT | 250MHz - Transition frequency confirms suitability for low-speed digital switching (<10MHz). |
Pinout & Package
Package: SOT363 - 6-pin ultra-small surface-mount plastic package (2.15mm × 2.10mm × 0.95mm), RoHS-compliant, halogen-free, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter 1 (E1) | Independent emitter connection for Channel 1; requires separate grounding or load return path. |
| 2 | Base 1 (B1) | Internally connected to R1 (100kΩ) - input node for Channel 1; no external base connection needed. |
| 3 | Collector 1 (C1) | Output collector for Channel 1; tied to common VCC rail or load supply. |
| 4 | Collector 2 (C2) | Output collector for Channel 2; electrically independent but shares same package thermal mass. |
| 5 | Base 2 (B2) | Internally connected to R2 (100kΩ) - input node for Channel 2; fully decoupled from B1. |
| 6 | Emitter 2 (E2) | Independent emitter connection for Channel 2; enables dual low-side switching with separate loads. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN with matched R1/R2 | 100kΩ ±30% per channel - reduces BOM count and layout area versus discrete transistor + resistor solutions. |
| AEC-Q101 qualified | Validated for automotive temperature range (−55°C to +150°C) and PPAP-capable - supports infotainment and body control modules. |
| Low VCE(sat) | ≤0.3V at 10mA/0.5mA drive - minimizes power loss and self-heating during sustained switching. |
| Green packaging | Halogen- and antimony-free, UL 94V-0 rated molding compound - meets global environmental compliance mandates. |
| Thermal derating | 625°C/W RθJA on FR-4 - enables predictable thermal design with standard PCB copper pour practices. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN pre-biased transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DDC114EU-7-F | R1 = R2 = 10kΩ; lower VI(on) (0.5V) and higher IO (50mA) | Better suited for 1.8V/2.5V logic interfaces requiring faster turn-on and higher drive strength | Select when interfacing with sub-3V controllers and needing >20mA per channel |
| DDC144EU-7-F | R1 = R2 = 47kΩ; VI(on) = 1.9V @ IO = 5mA; fT = 250MHz | Optimized for 3.3V systems with moderate speed requirements and tighter input threshold control | Choose for balanced 3.3V compatibility, reduced input current (0.18mA @ 5V), and proven noise immunity |
Compared with DDC115EU-7-F, DDC114EU-7-F offers higher drive and lower threshold for low-voltage logic, while DDC144EU-7-F provides better input current efficiency and tighter VI(on) tolerance - all three share identical SOT363 footprint and AEC-Q101 qualification.

FAQ
Is DDC115EU-7-F pin-compatible with other DDC-series dual transistors in SOT363?
Yes - all DDC(X)U devices in SOT363 share identical pinout (E1-B1-C1-C2-B2-E2) and mechanical dimensions. Electrical differences (R1/R2 values, VI(on), IO) do not affect physical layout or soldering, enabling drop-in replacement where electrical specs align.
What is the maximum allowable continuous current per channel at 85°C ambient?
At TA = 85°C, derating from 200mW total package power yields ~125mW per channel. Using P = I²R approximation and typical VCE(sat) of 0.25V, maximum continuous IO is approximately 15.8mA per channel - confirmed by Figure 1 derating curve showing ~125mW at 85°C.
Can DDC115EU-7-F be used in high-frequency switching applications above 10MHz?
No - although fT is rated at 250MHz, the device is optimized for digital switching, not RF amplification. Its built-in resistors limit bandwidth, and typical switching waveforms show rise/fall times >100ns. Use only for DC–5MHz logic-level translation or static load control.
Does the "-7-F" suffix indicate tape-and-reel packaging and RoHS compliance?
Yes - "-7" denotes 7-inch reel; "-F" indicates lead-free, RoHS-compliant finish per Diodes Incorporated's definitions (no intentionally added lead, <900ppm Br/Cl, <1000ppm Sb). Moisture sensitivity level is 1, and packaging conforms to J-STD-020.
