Product details
Overview
PDTC114YS,126 from NXP Semiconductors is an NPN resistor-equipped transistor (RET) in SOT323 (SC-70) surface-mount package, featuring integrated bias resistors R1 = 10 kΩ and R2/R1 = 4.7 ratio, 50 V VCEO, 100 mA IO, and AEC-Q101 qualification for automotive digital switching applications.
For engineers reviewing the PDTC114YS,126 datasheet, PDTC114YS,126 pinout, PDTC114YS,126 application, or PDTC114YS,126 equivalent, this device serves as a space- and BOM-optimized digital switch for IC input control, LED driving, and low-power load switching where built-in biasing eliminates external resistors and reduces PCB footprint.
Technical Context
The PDTC114YS,126 integrates a monolithic NPN transistor with two precision on-die resistors: R1 (input bias) and R2 (base-emitter feedback), forming a single-input, grounded-emitter digital switch topology. Its fixed R2/R1 ratio of 4.7 enables predictable saturation behavior across temperature.
Designed for direct interface with 3.3 V and 5 V logic families, it delivers guaranteed turn-on at VI(on) ≤ 0.8 V (IC = 1 mA) and turn-off at VI(off) ≥ 0.7 V (IC = 100 µA), supporting robust noise margin in automotive and industrial control nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports 24 V automotive supply rails with margin. |
| IO | 100 mA - Continuous output current capability; sufficient for driving small relays, LEDs, or logic inputs. |
| R1 | 10 kΩ (7–13 kΩ range) - Input bias resistor value; sets base current for logic-level drive without external components. |
| R2/R1 | 4.7 (3.7–5.7 range) - Feedback resistor ratio; ensures stable saturation and prevents deep cutoff during signal transitions. |
| VI(on) | ≤ 0.8 V @ IC = 1 mA - On-state input threshold; compatible with TTL and CMOS outputs down to 3.3 V. |
| VI(off) | ≥ 0.7 V @ IC = 100 µA - Off-state input threshold; provides ≥0.3 V noise immunity against ground bounce or EMI. |
| Ptot | 200 mW @ Tamb ≤ 25 °C - Total power dissipation limit; defines thermal derating envelope on standard FR4 PCB. |
Pinout & Package
SOT323 (SC-70) plastic surface-mounted package; 3-lead, 2.2 mm × 1.35 mm × 1.15 mm body size; lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level drive signal directly from MCU GPIO or buffer output. |
| 2 | GND (emitter) | Emitter tied to system ground; provides common reference for input and output paths. |
| 3 | Output (collector) | Switched high-side output node; sinks current from load connected between VCC and pin 3. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 + R2 bias network | Eliminates two external resistors, reducing BOM count and placement cost in high-volume digital interface designs. |
| AEC-Q101 qualification | Validated for automotive under-hood and cabin applications including body control modules and sensor interfaces. |
| 100 mA continuous output | Supports direct drive of indicators, small solenoids, and logic-level translators without external amplification. |
| Low VCE(sat) ≤ 100 mV | Minimizes conduction loss and self-heating when switching loads near rated current. |
| SOT323 compact footprint | Enables dense routing in space-constrained modules such as infotainment head units and ADAS ECUs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN digital switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTC114YU,115 | Same electrical specs and SOT323 package; differs only in tape-and-reel packing quantity (3000 vs. 10000 pcs/reel) and marking code (*30). | No functional difference; suitable for identical use cases and PCB layouts. | Select PDTC114YS,126 for standard 10,000-piece reels; choose PDTC114YU,115 for smaller-batch prototyping or JIT builds. |
| BC847B,215 | Discrete NPN transistor without integrated bias resistors; requires two external 10 kΩ and 47 kΩ resistors for equivalent function. | Higher BOM count and layout complexity; not AEC-Q101 qualified; lower production yield in automated assembly. | Use BC847B,215 only if RET architecture is incompatible with existing legacy schematics or thermal constraints demand separate resistor placement. |
Compared with PDTC114YU,115, the PDTC114YS,126 offers identical performance but optimized reel packaging for high-volume manufacturing; versus BC847B,215, it reduces component count by two and adds automotive-grade reliability without layout changes.

The PDTC114YS,126 supports a maximum continuous output current (IO) of 100 mA. This rating applies under standard conditions (Tamb ≤ 25 °C, FR4 PCB with single-sided copper). Derating is required above 25 °C per the published thermal resistance curve (Rth(j-a) = 625 K/W).
How does PDTC114YS,126 compare to BC847 series transistors?
PDTC114YS,126 is a cost-saving alternative to BC847/857 series in digital applications, offering identical switching functionality with integrated biasing. Unlike BC847B,215, it requires no external resistors, reduces PCB area, improves assembly yield, and adds AEC-Q101 qualification-making PDTC114YS,126 preferable for new automotive and industrial designs.
