Product details
Overview
DDTC113TLP-7 from Diodes Incorporated is a 50V NPN pre-biased small-signal transistor in DFN1006 package, featuring integrated 1kΩ base resistor (R1), hFE = 100–600 at IC = 1mA, VCE(sat) ≤ 0.25V at IC = 50mA/IB = 2.5mA, and AEC-Q101 qualification for automotive signal switching applications.
For engineers reviewing the DDTC113TLP-7 datasheet, DDTC113TLP-7 pinout, DDTC113TLP-7 application, or DDTC113TLP-7 equivalent, key selection criteria include its pre-biased configuration with single 1kΩ R1, ultra-small X1-DFN1006-3 footprint (1.0 × 0.6 mm), 250 mW power dissipation, and suitability for space-constrained logic-level interface and load switching in automotive ECUs and industrial sensors.
Technical Context
This device integrates an NPN transistor with a monolithic 1kΩ base-emitter resistor network, eliminating external bias components. It operates as a digital switch with guaranteed turn-on at VIN ≥ 1.0V and full saturation at IC ≤ 100mA, supporting TTL/CMOS-compatible input drive.
The X1-DFN1006-3 package features exposed collector pad for thermal conduction, NiPdAu-plated terminals, and J-STD-020 Level 1 moisture sensitivity-enabling high-yield reflow assembly without preconditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum allowable collector-emitter voltage before breakdown; enables use in 24V automotive supply rails with margin. |
| hFE | 100–600 - DC current gain range at VCE = 5V, IC = 1mA; ensures reliable switching across process variation. |
| VCE(sat) | ≤ 0.25 V - Saturation voltage at IC = 50mA/IB = 2.5mA; minimizes power loss in active-switching mode. |
| R1 | 0.7–1.3 kΩ - Integrated base resistor tolerance; eliminates need for external bias network and reduces PCB area. |
| PD | 250 mW - Power dissipation on standard FR4 board; supports continuous operation up to +100°C ambient with derating. |
| fT | 250 MHz - Current-gain bandwidth product at VCE = 10V, IE = 5mA; suitable for low-speed digital switching (<10 MHz). |
Pinout & Package
Package: X1-DFN1006-3 - ultra-compact 1.0 mm × 0.6 mm leadless plastic package with exposed collector pad (Pin 1), compliant with AEC-Q101 and RoHS.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Collector) | Main current output path | Exposed metal pad thermally and electrically connected to collector; must be soldered to PCB copper for thermal management. |
| 2 (Base) | Control input node | Connected internally to 1kΩ resistor; accepts logic-level drive (0–10V) without external bias components. |
| 3 (Emitter) | Current return path | Internally tied to R1; referenced to system ground in common-emitter switching configurations. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive temperature range (−55°C to +150°C) and mechanical stress; supports under-hood ECU deployment. |
| Pre-biased configuration | Single integrated 1kΩ R1 eliminates two external resistors, reducing BOM count and layout area by >30% vs discrete bias design. |
| Lead-free & Halogen-free | Meets RoHS 2 and JEDEC JS709C "Green" requirements (<900 ppm Br/Cl, <1000 ppm Sb); compliant for global automotive supply chains. |
| Level 1 moisture sensitivity | No baking required prior to reflow; compatible with standard SMT lines without process modification. |

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 |
|---|---|---|---|
| NSVD113T1T5G | Same R1 = 1kΩ, but hFE min = 30 (vs. 100); VCE(sat) max = 0.3 V at same test condition. | Lower gain requires higher drive current; less suitable for weak GPIO sources. | Prefer DDTC113TLP-7 when driving marginally loaded logic interfaces or low-IB MCUs. |
| DXTN113TK-7 | Higher VCEO = 60V, same R1/hFE, but in SOT-323 (2.1 × 1.3 mm) - 3.5× larger footprint. | Acceptable where board space allows and 60V headroom is needed for transient suppression. | Choose DDTC113TLP-7 for space-constrained designs requiring AEC-Q101 and minimal footprint. |
Compared with NSVD113T1T5G and DXTN113TK-7, DDTC113TLP-7 delivers superior gain consistency, tighter VCE(sat), and the smallest qualified footprint-making it optimal for high-density automotive and industrial control modules where reliability and miniaturization are jointly critical.

FAQ
What is the function of the integrated 1kΩ resistor in DDTC113TLP-7?
The integrated 1kΩ resistor connects between base and emitter, forming a built-in bias network that eliminates the need for external base resistors. This enables direct connection to logic-level drivers (e.g., 3.3V/5V GPIO), ensures predictable turn-on behavior, and reduces PCB component count and layout area in digital switching applications.
Can DDTC113TLP-7 replace a standard NPN transistor like BC847 in existing designs?
Yes-but only if the circuit relies on fixed-base-current drive and does not require adjustable bias. DDTC113TLP-7's internal R1 fixes the base-emitter path, so it cannot substitute for discrete transistors used in linear amplifier or variable-bias configurations. Verify saturation voltage and gain match at target IC before replacement.
Is DDTC113TLP-7 suitable for PWM motor control?
It supports PWM operation up to ~5 kHz with acceptable switching losses due to its 250 MHz fT and low VCE(sat). However, it is rated for 100 mA IC(MAX) and 250 mW PD, limiting use to small fans or indicator loads-not brush motors or high-current actuators. Thermal design must account for ambient derating above +25°C.
Does DDTC113TLP-7 require special PCB layout considerations?
Yes-the exposed collector pad (Pin 1) must be fully soldered to a minimum 1 oz copper thermal pad per Diodes AP02001 guidelines. Insufficient pad area or poor solder wetting increases θJA beyond 500°C/W, risking thermal runaway at >150 mW. Avoid thermal relief spokes on this pad.
