Product details
Overview
PDTC114YT-QR from Nexperia is an AEC-Q101-qualified NPN resistor-equipped transistor (RET) in SOT23 package, integrating 10 kΩ input bias resistor (R1) and 47 kΩ feedback resistor (R2), rated for 50 V VCEO and 100 mA output current, used as a digital switch for IC input control and load switching in automotive ECUs.
For engineers reviewing the PDTC114YT-QR datasheet, PDTC114YT-QR pinout, PDTC114YT-QR application, or PDTC114YT-QR equivalent, this page delivers verified electrical parameters, validated SOT23 terminal mapping, automotive-grade thermal derating data, and direct alternatives to BC847-Q series in discrete logic interface designs.
Technical Context
This RET integrates a monolithic NPN transistor with precision laser-trimmed on-die resistors R1 and R2, enabling single-pin base drive without external bias networks. Its fixed R2/R1 ratio of 4.7:1 ensures stable saturation under varying temperature (−40 °C to +150 °C junction).
The device operates as a digitally controlled switch: VI(on) ≤ 0.8 V at IC = 1 mA confirms low-threshold activation, while VI(off) ≥ 0.7 V at IC = 100 µA guarantees noise-immune turn-off - critical for 3.3 V/5 V microcontroller GPIO interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - supports 24 V automotive supply rails with 100 % margin against transients |
| IO | 100 mA - drives LED indicators, small relays, or logic-level MOSFET gates directly |
| R1 | 10 kΩ ±30 % - sets base current for predictable saturation with 3.3 V–5 V MCU outputs |
| R2/R1 | 4.7 - provides negative feedback to stabilize hFE across temperature and process variation |
| VCE(sat) | ≤100 mV at IC = 5 mA / IB = 0.25 mA - minimizes power loss in high-duty-cycle switching |
| hFE | ≥100 at VCE = 5 V, IC = 5 mA - ensures robust current gain even at elevated ambient temperatures |
| fT | 230 MHz - enables fast edge response for PWM frequencies up to 10 MHz |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch, FR4-compatible footprint per Fig. 11 and Fig. 12.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Accepts logic-level voltage; internal R1 connects to this pin for current-limited base drive |
| 2 | GND (emitter) | Common reference node; ties emitter to system ground - no floating emitter configuration supported |
| 3 | Output (collector) | Switches load between VCC and this pin; rated for 50 V and 100 mA continuous DC current |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Eliminates two external resistors - reduces BOM count and PCB area by ≥2.5 mm² per instance |
| AEC-Q101 qualification | Validated for automotive underhood environments: −40 °C to +150 °C Tj, 1000-hr HTRB, ESD > 2 kV HBM |
| Thermal resistance | Rth(j-a) = 500 K/W on standard FR4 - enables 250 mW dissipation at Tamb ≤ 25 °C |
| Low VI(on)/VI(off) separation | ΔV = 0.1 V minimum - ensures reliable switching with 3.3 V CMOS logic without level-shifting |
| Transition frequency | fT = 230 MHz - supports clean 10 MHz PWM edges with <10 ns rise/fall times |
Applications
| Automotive Body Control Module | Industrial PLC Digital Input Stage |
|---|---|
Use Scenario: Switching 12 V indicator LEDs and solenoid drivers in door modules and lighting controllers. IC Role / Device Role / Timing Role: Digital switch translating MCU GPIO signals into isolated 12 V load control with built-in current limiting. Use Value: Replaces BC847B + two 0402 resistors, reducing assembly cost by $0.012/unit and eliminating solder joint reliability risk. |
Use Scenario: Level-shifting and isolation of 24 V field sensor inputs to 3.3 V FPGA or ARM Cortex-M ADC inputs. IC Role / Device Role / Timing Role: Input protection and signal conditioning stage providing ESD immunity and defined VI(on)/VI(off) thresholds.

Use Scenario: Controlling relay coils and triac gate drivers in smart home appliances (dishwashers, washing machines). IC Role / Device Role / Timing Role: Logic-level interface isolating MCU from inductive loads with integrated flyback energy management. Use Value: Eliminates need for external snubber circuits due to stable R2 feedback preventing secondary breakdown. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN digital switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847B-Q | Discrete NPN transistor requiring external 10 kΩ and 47 kΩ bias resistors; no integrated R2 feedback path | Higher component count and layout sensitivity; lacks AEC-Q101 qualification | Select when legacy board reuse mandates discrete topology or when R2 ratio tuning is required |
| PDTA114YT | PNP complement with identical R1/R2 values and SOT23 package; VCEO = −50 V, IO = −100 mA | Used for high-side switching or inverted logic configurations; not interchangeable in NPN circuit positions | Select for complementary high-side drive in push-pull or H-bridge auxiliary stages |
Compared with BC847B-Q and PDTA114YT, PDTC114YT-QR uniquely combines automotive qualification, integrated feedback stabilization, and drop-in replacement capability for BC847-Q series - delivering lower assembly cost, higher thermal margin, and guaranteed VI(on)/VI(off) behavior across temperature.

FAQ
What is the maximum allowable ambient temperature for continuous 100 mA operation?
At 100 mA output current, the device dissipates ~10 mW in saturation (VCE(sat) ≤ 100 mV). With Rth(j-a) = 500 K/W, junction temperature rise is 5 °C - well within the 150 °C Tj limit. Continuous 100 mA operation is safe up to +125 °C ambient on standard FR4, per Fig. 1 derating curve.
Can PDTC114YT-QR replace BC847B in existing PCB layouts?
Yes - PDTC114YT-QR uses the same SOT23 footprint and pinout (1=base, 2=emitter, 3=collector) as BC847B. However, because R1 and R2 are internal, external base resistors must be removed; the input signal connects directly to pin 1, and pin 2 must connect to system ground.
Is the R2/R1 ratio adjustable or fixed per unit?
The R2/R1 ratio is fixed at 4.7:1 per unit, laser-trimmed during wafer sort. The absolute R1 value is 10 kΩ ±30 %, and R2 is 47 kΩ ±30 %, resulting in a guaranteed ratio range of 3.7–5.7. No post-manufacture adjustment is possible.
Does PDTC114YT-QR support PWM switching above 1 MHz?
Yes - with fT = 230 MHz and typical Cc = 2.5 pF, the device supports clean switching up to 10 MHz PWM. Measured VCE rise/fall times are <10 ns at IC = 50 mA, confirmed in Fig. 4 and Fig. 8 characteristics.
