Product details
Overview
DDTC114GUA-7-F from Diodes Incorporated is an NPN pre-biased small-signal transistor in SOT-323 package, featuring a single built-in 10 kΩ bias resistor (R2 only), 50 V VCEO, 100 mA IC(max), and hFE = 30–100 at IC = 5 mA, used in digital logic interface and level-shifting circuits for portable consumer electronics.
For engineers reviewing the DDTC114GUA-7-F datasheet, DDTC114GUA-7-F pinout, DDTC114GUA-7-F application, or DDTC114GUA-7-F equivalent, this page delivers verified electrical specs, terminal mapping, real-world use cases, and validated alternatives for discrete BJT selection in space-constrained PCB designs.
Technical Context
This device integrates a monolithic NPN transistor with a dedicated emitter-base biasing resistor (R2 = 10 kΩ ±30%), eliminating external base resistors in simple switching applications. It operates with VCEO = 50 V, VEB0 = 5 V, and exhibits VCE(sat) ≤ 0.3 V at IC = 10 mA / IB = 0.5 mA.
The SOT-323 package supports surface-mount assembly with JEDEC-compliant pad layout (AP02001), moisture sensitivity level 1, and thermal resistance RθJA = 625 °C/W on FR4 board - enabling reliable operation from –55 °C to +150 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; defines safe DC/peak swing in low-voltage switching rails. |
| IC(max) | 100 mA - Continuous collector current limit; sets upper bound for load-driving capability in GPIO-driven stages. |
| R2 | 10 kΩ ±30% - Integrated base-emitter bias resistor; enables single-resistor-free switch configuration without external pull-up/down. |
| hFE | 30–100 @ IC = 5 mA - DC current gain range; determines required base drive margin for saturation in digital interface applications. |
| VCE(sat) | ≤ 0.3 V @ IC = 10 mA, IB = 0.5 mA - Low saturation voltage ensures minimal power loss and voltage drop in active-low output stages. |
| PD | 200 mW - Maximum power dissipation at TA = 25 °C; constrains usable duty cycle and ambient temperature in compact layouts. |
Pinout & Package
SOT-323 plastic surface-mount package with three terminals: Emitter (E), Base (B), Collector (C); dimensions per JEDEC MO-203AA (A = 0.25–0.40 mm, C = 2.00–2.20 mm, H = 1.80–2.20 mm); lead-free matte tin plating over Alloy 42 leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| E (Emitter) | Current sink node | Connected to ground or low-side return path; carries full load current in common-emitter switch configuration. |
| B (Base) | Control input node | Internally connected to R2; accepts TTL/CMOS logic-level drive without external bias network. |
| C (Collector) | Output node | Drives load between VCC and collector; configured as open-collector output in active-low signaling. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R2 bias resistor | 10 kΩ ±30% - Reduces BOM count and PCB area by replacing discrete base resistor in digital switch designs. |
| Low VCE(sat) | ≤ 0.3 V - Minimizes conduction loss and self-heating in battery-powered devices operating at 3.3 V or 5 V rails. |
| Moisture Sensitivity Level | Level 1 per J-STD-020C - Eliminates bake requirements prior to reflow, simplifying manufacturing flow for high-volume SMT lines. |
| Green molding compound | Halogen-free, RoHS-compliant - Meets environmental compliance mandates for CE-marked consumer and industrial end equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN pre-biased transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSV114GUT1G | R2 = 10 kΩ, but hFE min = 20 (vs. 30) and PD = 150 mW (vs. 200 mW) | Lower gain and power rating reduce margin in high-current or thermally dense designs | Acceptable for low-duty-cycle indicator loads where thermal headroom is ample |
| EMH11T2R | R2 = 10 kΩ, but VCEO = 40 V (vs. 50 V) and VCE(sat) = 0.4 V (vs. 0.3 V) | Reduced voltage headroom and higher saturation loss limit use in 5 V systems with tight noise margins | Preferred only when footprint compatibility with EMT3 package is mandatory |
Compared with NSV114GUT1G and EMH11T2R, DDTC114GUA-7-F offers superior voltage rating, lower saturation voltage, and higher power handling - making it optimal for 5 V logic interfaces requiring robustness and efficiency in compact SOT-323 layouts.

FAQ
What is the exact pin configuration for DDTC114GUA-7-F in SOT-323?
The DDTC114GUA-7-F uses standard SOT-323 pinout: Pin 1 = Emitter (E), Pin 2 = Base (B), Pin 3 = Collector (C). This matches JEDEC MO-203AA orientation with emitter adjacent to the tab notch. Terminal polarity and function are confirmed in Diodes' DS30324 Rev. 7 schematic diagram and mechanical drawing.
Does DDTC114GUA-7-F require an external base resistor?
No - DDTC114GUA-7-F integrates a single 10 kΩ bias resistor (R2) between base and emitter, enabling direct connection to CMOS/TTL logic outputs without external components. This eliminates risk of incorrect biasing and reduces layout complexity in GPIO-driven switching applications.
Can DDTC114GUA-7-F replace a standard NPN transistor like BC847?
It can replace BC847 in simple switching roles only if the circuit relies on fixed base bias and does not require adjustable gain or dual-resistor (R1+R2) bias networks. Unlike BC847, DDTC114GUA-7-F lacks independent base access, so it is unsuitable for linear amplification or feedback-controlled configurations.
What is the maximum operating temperature for continuous use?
DDTC114GUA-7-F supports continuous operation from –55 °C to +150 °C junction temperature. At ambient temperatures above 70 °C, derating applies: power dissipation must be reduced linearly per the 625 °C/W RθJA curve in Figure 1 of DS30324, reaching 0 mW at 150 °C case temperature.
