Product details
Overview
DDC114TU-7 from Diodes Incorporated is a dual NPN pre-biased small-signal transistor in SOT-363 package, featuring integrated 10 kΩ and 10 kΩ bias resistors (R1/R2), 50 V VCEO, 100 mA IO, 0.3 V VCE(sat) at 10 mA/1 mA, and 100–600 hFE at IC = 1 mA. It serves as a compact logic-level switch in space-constrained digital interface circuits.
For engineers reviewing the DDC114TU-7 datasheet, DDC114TU-7 pinout, DDC114TU-7 application, or DDC114TU-7 equivalent, key selection criteria include verified R1/R2 resistor values, guaranteed VCE(sat) under defined IC/IB conditions, hFE range at low-current switching, and thermal derating compliance up to +150°C ambient.
Technical Context
This device integrates two identical NPN transistors with monolithically embedded base-emitter biasing networks-each with matched 10 kΩ input resistors (R1) and 10 kΩ emitter resistors (R2)-enabling direct TTL/CMOS-compatible drive without external bias components. Its complementary DDA-series PNP variants support push-pull configurations.
Designed for surface-mount logic interfacing, it operates across –55°C to +150°C with 625°C/W junction-to-ambient thermal resistance on FR4 PCBs using recommended pad layout. Maximum per-element power dissipation is limited to 150 mW, consistent with its 200 mW total package rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - supports rail-to-rail switching in 3.3 V and 5 V logic systems with margin against transients |
| IO (max) | 100 mA - sufficient for driving LED indicators, small relays, or gate inputs of downstream logic |
| VCE(sat) | 0.3 V at IC/IB = 10 mA/1 mA - ensures low conduction loss and minimal voltage drop in active-switch mode |
| hFE | 100–600 at IC = 1 mA, VCE = 5 V - provides stable current amplification across production lot variation |
| R1 / R2 | 10 kΩ / 10 kΩ ±30% - enables predictable turn-on threshold and eliminates discrete bias resistor placement |
| fT | 250 MHz - supports high-speed digital switching up to ~20–30 MHz edge rates in clean signal paths |
Pinout & Package
Package: SOT-363 (SC-88), 6-pin ultra-small outline surface-mount package with lead-free matte tin finish over Alloy 42 leadframe; moisture sensitivity level 1 per J-STD-020C; UL 94V-0 rated molded plastic body; weight ≈ 0.006 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 3 (Collector 1) | Collector terminal of first NPN transistor | Active output node; sinks load current when driven; compatible with open-collector interface standards |
| 4 (Emitter 2) | Emitter terminal of second NPN transistor | Independent emitter node; allows separate grounding or biasing of dual channels |
| 5 (Base 2) | Base terminal of second NPN transistor | Duplicate of Pin 2; electrically isolated but identically biased; enables independent control |
| 6 (Collector 2) | Collector terminal of second NPN transistor | Second independent switched output; supports dual-channel logic buffering or redundancy |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN with matched bias network | Two fully independent pre-biased transistors sharing one SOT-363 footprint; reduces board area by >40% vs. discrete solutions |
| Guaranteed VCE(sat) at 10 mA/1 mA | Ensures reliable saturation under standard microcontroller GPIO drive conditions without external current limiting |
| Wide operating temperature range | –55°C to +150°C operation validated per JEDEC JESD22-A108; suitable for automotive under-hood and industrial control environments |

Use Value: Supports continuous 100 mA switching at +85°C ambient with no contact wear, reducing maintenance cycles and failure modes. | Use Scenario: Controlling interior lighting dimming circuits and door lock actuators in a BCM where ESD robustness and AEC-Q101 qualification are mandatory. IC Role / Device Role / Timing Role: Pre-biased switching element in high-side driver auxiliary paths, interfacing with LIN bus-controlled microcontrollers. Use Value: Integrated 10 kΩ bias resistors simplify layout near noisy power domains and improve immunity to coupled transients on shared PCB layers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar pre-biased transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DDC114EU-7 | R1 = 10 kΩ, R2 = 10 kΩ, same VCEO/IO, but hFE min = 50 (vs. 100 for DDC114TU-7) | Limited to lower-gain switching where base drive margin is ample; not recommended for marginal GPIO drive | Select DDC114EU-7 only if cost sensitivity outweighs guaranteed minimum gain and design margin is verified |
| DDC143TU-7 | R1 = 4.7 kΩ, R2 = 47 kΩ, same VCEO/IO, but optimized for higher-speed switching (lower input impedance) | Better suited for 25+ MHz clocked interfaces; less tolerant of weak MCU outputs due to lower VIN(on) | Choose DDC143TU-7 when driving fast digital signals with strong source capability and need for reduced propagation delay |
Compared with DDC114EU-7, DDC114TU-7 guarantees higher minimum hFE for robust low-current switching, while DDC143TU-7 trades gain stability for faster response via lower R1-making DDC114TU-7 optimal for general-purpose logic interfacing with marginal drive strength.

FAQ
Is DDC114TU-7 pin-compatible with other SOT-363 pre-biased transistors?
Yes-DDC114TU-7 uses the standard SOT-363 pinout (Emitter1/Base1/Collector1/Emitter2/Base2/Collector2), matching industry-standard footprints including those of the DDC114EU-7, DDC143TU-7, and DDC124EU-7. Mechanical compatibility is confirmed per Diodes' AP02001 land pattern guidelines.
What is the maximum safe operating current per channel at +105°C ambient?
At +105°C ambient, derating per Figure 1 requires limiting power dissipation to ~125 mW. With VCE(sat) = 0.3 V, this supports ≤41 mA continuous collector current per channel-well within the 100 mA absolute max rating but constrained by thermal limits in enclosed assemblies.
Does DDC114TU-7 meet AEC-Q101 for automotive use?
No-DDC114TU-7 is not AEC-Q101 qualified. While it operates from –55°C to +150°C and features robust construction, Diodes Incorporated does not list it in their AEC-Q101 stress-tested portfolio. For automotive applications, consider the AEC-Q101-qualified DDC114YU-7 variant instead.
Can DDC114TU-7 be used in linear amplifier configurations?
No-it is designed exclusively for saturated switching operation. The integrated bias resistors fix the base-emitter operating point, and its hFE specification is only guaranteed in active-region test conditions (IC = 1 mA, VCE = 5 V), not for linear gain stability or bandwidth linearity.
