Product details
Overview
PDTC114ET-QR from Nexperia is an AEC-Q101-qualified NPN resistor-equipped transistor (RET) in SOT23 package, integrating 10 kΩ base bias resistor R1 and 10 kΩ feedback resistor R2. It delivers 100 mA output current with 50 V VCEO, operates as a digital switch for IC inputs and load control in automotive ECUs and industrial controllers, and replaces discrete BJT + two resistors in level-shifting and logic interfacing circuits.
For engineers reviewing the PDTC114ET-QR datasheet, PDTC114ET-QR pinout, PDTC114ET-QR application, or PDTC114ET-QR equivalent, this page provides verified pin functions, automotive-grade thermal derating data, confirmed R1/R2 ratio of 1.0, VI(on)/VI(off) thresholds at 25 °C and 100 °C, and direct alternatives to BC847-Q series in cost-sensitive digital switching designs.
Technical Context
This RET integrates a monolithic NPN transistor with two precision laser-trimmed on-die resistors: R1 connects base to input, R2 connects base to emitter. Its fixed R2/R1 ratio of 1.0 enables predictable saturation behavior under varying temperature (−40 °C to +150 °C junction), eliminating external bias network design effort.
The device operates in saturated switch mode with guaranteed VCEsat ≤ 100 mV at IC = 10 mA / IB = 0.5 mA, and supports fast switching via fT = 230 MHz (built-in transistor). Input voltage thresholds VI(on) = 1.8 V (typ) and VI(off) = 1.1 V (typ) ensure robust noise margin against 3.3 V/5 V logic levels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports 24 V automotive supply rails with safety margin. |
| IO | 100 mA - Continuous output current capability; sufficient for driving LEDs, small relays, and logic inputs. |
| R1 | 10 kΩ (7–13 kΩ) - Integrated base pull-up resistor; sets input current for reliable turn-on without external components. |
| R2/R1 | 1.0 (0.8–1.2) - Fixed feedback ratio enabling stable saturation and predictable off-state leakage suppression. |
| VCEsat | ≤100 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 edge integrity up to ~10 MHz digital switching. |
| Ptot | 250 mW at Tamb ≤ 25 °C - Total power dissipation limit on FR4 PCB; derates linearly to zero at 150 °C ambient. |
Pinout & Package
SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pin pitch); thermally optimized for reflow soldering on single-sided FR4 PCBs with 35 μm tin-plated copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connects to logic signal source; internally tied to R1 top node and R2 top node - serves as combined bias input terminal. |
| 2 | GND (emitter) | Emitter reference and return path; internally connected to R2 bottom node - forms common ground for both resistors and transistor emitter. |
| 3 | Output (collector) | Switched high-side output node; connects to load (e.g., LED anode or relay coil); collector current flows out through this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in dual-resistor network | Eliminates need for two external bias resistors, reducing BOM count by 2 parts and saving 1.5 mm² PCB area. |
| AEC-Q101 qualification | Validated for automotive applications including engine control modules, body electronics, and ADAS sensor interfaces. |
| Guaranteed VI(on)/VI(off) thresholds | VI(on) ≤ 2.5 V and VI(off) ≥ 0.8 V at 25 °C ensure compatibility with 3.3 V CMOS and TTL logic families. |
| Thermal derating curve provided | Linear Ptot reduction from 250 mW at 25 °C to 0 mW at 150 °C enables accurate thermal design on standard FR4. |
| Low VCEsat with defined test condition | VCEsat ≤ 100 mV tested at IC/IB = 20 ensures predictable power loss in production environments. |
Applications
| Automotive Body Control Module | Industrial PLC Digital Input Stage |
|---|---|
Use Scenario: Level-shifting 5 V microcontroller GPIO to drive 12 V lamp loads in door module PCBs. IC Role / Device Role / Timing Role: NPN RET acts as active-low digital switch, sinking current from lamp cathode to ground when MCU pin is high.

Use Scenario: Isolating 24 V field sensor signals into 3.3 V FPGA I/O banks in modular I/O cards. IC Role / Device Role / Timing Role: Acts as voltage translator and current limiter; input pin accepts 24 V logic-high, collector pulls FPGA pin low via optocoupler LED driver. Use Value: Built-in R1/R2 ratio of 1.0 ensures consistent turn-on threshold across −40 °C to +125 °C ambient, eliminating calibration drift. |
| Consumer Appliance Motor Driver Interface | Medical Diagnostic Equipment Power Sequencing |

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-Q | Discrete NPN BJT without integrated resistors; requires external R1/R2 network. | Higher BOM count and layout sensitivity; lacks AEC-Q101 qualification out-of-box. | Select when fine-tuning R1/R2 values is required or when legacy footprint reuse is mandatory. |
| PDTA114ET-Q | PNP complement with identical R1/R2 values and AEC-Q101 rating; VECO = 50 V, IO = −100 mA. | Used for high-side switching where load connects to VCC; not interchangeable in low-side configurations. | Select for complementary high-side control in same automotive subsystem (e.g., paired with PDTC114ET-Q in H-bridge enable logic). |
Compared with BC847B-Q, PDTC114ET-QR reduces component count and improves thermal stability; compared with PDTA114ET-Q, it provides low-side sink capability essential for logic-level interfacing and LED driving.

FAQ
What is the maximum allowable junction temperature for PDTC114ET-QR?
The absolute maximum junction temperature (Tj) is 150 °C, as defined in IEC 60134 limiting values. Operation above this temperature risks permanent degradation of the integrated resistors and transistor gain. Thermal design must use the provided Rth(j-a) = 500 K/W and derating curve to ensure Tj remains within limit under worst-case ambient and power conditions.
Can PDTC114ET-QR be used with 1.8 V logic inputs?
No - VI(on) is specified as 2.5 V (max) at IC = 10 mA, meaning reliable turn-on requires ≥2.5 V input. At 1.8 V, the device remains in cutoff (VI(off) = 1.1 V typ), resulting in no collector current flow. It is designed for 3.3 V or 5 V logic families, not sub-2 V I/O standards.
Is the R1/R2 ratio adjustable or fixed per unit?
The R2/R1 ratio is fixed at 1.0 (with tolerance 0.8–1.2) per device, determined by on-die resistor trimming during wafer sort. It cannot be adjusted post-manufacture. This fixed ratio ensures consistent saturation characteristics and eliminates variability introduced by discrete resistor matching tolerances.
Does PDTC114ET-QR support pulsed operation beyond 100 mA?
No - the 100 mA rating is the absolute maximum continuous output current (IO). Pulse operation is not characterized in the datasheet, and exceeding 100 mA even briefly violates the Absolute Maximum Rating for IO. For higher peak currents, a discrete BJT with external biasing or a dedicated load switch IC should be selected.
