Product details
Overview
PDTC114ET/DG/B4,21 from Nexperia is an NPN resistor-equipped transistor (RET) in SOT23 package, designed for digital switching applications with integrated 10 kΩ input and feedback bias resistors (R1 = R2 ≈ 10 kΩ), 50 V VCEO, 100 mA IO, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PDTC114ET/DG/B4,21 datasheet, PDTC114ET/DG/B4,21 pinout, PDTC114ET/DG/B4,21 application, or PDTC114ET/DG/B4,21 equivalent, this device serves as a drop-in replacement for BC847-series transistors in logic-level interface and load-switching circuits where bias resistor integration reduces PCB area and assembly cost.
Technical Context
This RET integrates a monolithic NPN transistor with two precision silicon-based bias resistors (R1 = 10 kΩ, R2/R1 = 1.0 typ) to form a single-input, grounded-emitter switch. It operates with VI(on) = 1.8–2.5 V and VI(off) = 0.8–1.1 V at IC = 10 mA, enabling direct interfacing with 3.3 V and 5 V logic families.
The device delivers hFE ≥ 30 at IC = 5 mA and VCE = 5 V, with VCE(sat) ≤ 150 mV at IC = 10 mA/IB = 0.5 mA, ensuring low conduction loss in digital control paths. Its fT = 230 MHz supports fast edge transitions in timing-critical switching nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V automotive supply rails with margin. |
| IO | 100 mA - Continuous output current capability; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 | 10 kΩ (7–13 kΩ) - Input bias resistor value; sets base current for predictable turn-on without external components. |
| R2/R1 | 1.0 (0.8–1.2) - Matched feedback-to-input resistor ratio; ensures stable saturation and prevents latch-up under noise. |
| VCE(sat) | ≤150 mV at IC = 10 mA/IB = 0.5 mA - Low saturation voltage minimizes power loss and self-heating in high-duty-cycle switching. |
| fT | 230 MHz - Transition frequency of internal transistor; supports clean switching up to ~10–20 MHz digital signals. |
| AEC-Q101 | Qualified - Meets automotive stress test requirements for temperature cycling, HTRB, and ESD; suitable for under-hood modules. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package: 3-pin, 1.9 mm × 1.1 mm × 1.2 mm body, standard footprint compatible with reflow soldering only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level drive directly from MCU GPIO or buffer output. |
| 2 | GND (emitter) | Common emitter reference node; must be tied to system ground for proper biasing and current return path. |
| 3 | Output (collector) | Switched high-side load connection point; sinks current when active, supports open-collector-style interfacing. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in bias resistors | Eliminates need for two external 10 kΩ resistors per switch, reducing BOM count and layout area by ~30% vs discrete BC847 + R1/R2. |
| 100 mA output rating | Supports direct driving of indicator LEDs (20 mA), small solenoids (<50 mA), and CMOS/TTL inputs without additional gain stages. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTOL, temperature cycling, and ESD (HBM ≥2 kV), enabling use in ADAS sensor interfaces. |
| Low VCE(sat) | 150 mV max ensures <1.5 mW conduction loss at 10 mA, minimizing thermal rise in dense PCB layouts and enabling higher channel density. |
| Standard SOT23 footprint | Enables drop-in replacement of legacy transistors (e.g., BC847B) using existing pick-and-place programs and stencil designs. |
Applications
| Automotive LED Lighting Control | Industrial PLC Digital Input Conditioning |
|---|---|
|
Use Scenario: Driving 12 V LED strings in interior lighting modules with PWM dimming from 3.3 V microcontroller outputs. IC Role / Device Role / Timing Role: NPN switch with integrated biasing, acting as level-shifting current sink between low-voltage logic and higher-voltage loads. Use Value: Eliminates external base resistors and reduces component count per channel, improving manufacturing yield and long-term reliability in vibration-prone environments. |
Use Scenario: Converting 24 V field sensor signals into clean 3.3 V logic-compatible inputs for ARM-based PLC controllers. IC Role / Device Role / Timing Role: Digital interface translator providing galvanic isolation support via optocoupler driver stage and noise-immune threshold switching. Use Value: Built-in resistor matching ensures consistent VI(on)/VI(off) across temperature (−40 °C to +125 °C), reducing calibration overhead in factory automation systems. |
| Consumer Appliance Motor Enable Logic | Medical Diagnostic Device Signal Gating |
|
Use Scenario: Enabling brushed DC fan motors in smart HVAC units using MCU GPIO pins with limited drive strength. IC Role / Device Role / Timing Role: High-side load switch controller (with external P-MOSFET) or low-side motor driver stage handling 50–100 mA peak currents. Use Value: 100 mA rating and 50 V VCEO allow safe operation during inductive kickback, while AEC-Q101 qualification supports extended service life in continuous-use appliances. |
Use Scenario: Gating analog sensor signals (e.g., ECG front-end) during power-down sequences to prevent leakage-induced baseline drift. IC Role / Device Role / Timing Role: Precision-controlled analog switch enable/disable element, leveraging low ICEO (<1 µA) and tight R1/R2 matching for repeatable turn-off behavior. Use Value: Sub-µA off-state leakage and stable hFE over temperature ensure signal integrity in battery-powered portable diagnostics with multi-year shelf life. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847B,215 | Discrete NPN transistor requiring external 10 kΩ base resistors; no built-in R2 feedback path; hFE = 200–450 (wider spread). | Higher design flexibility but increases component count, layout area, and sensitivity to trace parasitics in high-density boards. | Select when precise hFE tuning or non-standard bias ratios are required; avoid if minimizing assembly steps is critical. |
| PDTA114ET,215 | PNP complement in identical SOT23 package; same R1/R2 values but inverted polarity; VECO = 50 V, IO = −100 mA. | Used for high-side switching or complementary logic gates; not interchangeable without circuit topology changes. | Select only for PNP-side switching in push-pull or dual-rail configurations; requires schematic revision versus PDTC114ET. |
Compared with BC847B,215, PDTC114ET/DG/B4,21 reduces bill-of-materials and improves production consistency via monolithic resistor matching; compared with PDTA114ET,215, it provides complementary NPN functionality with identical footprint but opposite current direction-requiring deliberate topology alignment.

FAQ
What is the maximum operating temperature for PDTC114ET/DG/B4,21?
The junction temperature (Tj) is rated up to 150 °C, and ambient operating range extends from −65 °C to +150 °C. Thermal resistance Rth(j-a) is 500 K/W on FR4 PCB with standard footprint, meaning power dissipation must be limited to ≤250 mW at 25 °C ambient to stay within limits.
Can PDTC114ET/DG/B4,21 replace BC847B in existing designs?
Yes-PDTC114ET/DG/B4,21 uses the same SOT23 package and pinout (1=base, 2=emitter, 3=collector), and its integrated 10 kΩ R1/R2 eliminates external resistors. However, verify VI(on)/VI(off) thresholds match your logic family, as BC847B lacks built-in biasing and requires external resistor selection.
Is wave soldering supported for this device?
No-reflow soldering is the only recommended method per Nexperia's documentation. Wave soldering is explicitly not qualified for PDTC114ET/DG/B4,21 due to thermal stress risks on the internal resistor network and die attach; use only JEDEC-compliant reflow profiles.
What does the marking "*16" indicate on PDTC114ET/DG/B4,21?
The marking code "*16" (per Table 5) identifies the PDTC114ET variant, where "*" is a placeholder for the manufacturing site code and "16" denotes the specific device type within the PDTC114E series. This matches the SOT23 package and electrical specifications defined in the datasheet Rev. 12.
