Product details
Overview
PDTC114ET215 from Nexperia is an NPN resistor-equipped transistor (RET) in SOT23 package, designed for digital switching applications with built-in bias resistors R1 = 10 kΩ and R2 = 10 kΩ, 50 V VCEO, 100 mA IO, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PDTC114ET215 datasheet, PDTC114ET215 pinout, PDTC114ET215 application, or PDTC114ET215 equivalent, this discrete NPN RET simplifies load switching, IC input control, and level translation in space-constrained industrial and automotive PCBs where component count reduction and reflow-solderable reliability are critical.
Technical Context
This device integrates a monolithic NPN transistor with two precision on-die bias resistors-R1 connected between base and input, R2 between base and emitter-enabling single-resistor drive from logic-level sources without external bias networks. It operates as a saturated switch with guaranteed VCE(sat) ≤ 150 mV at IC = 10 mA / IB = 0.5 mA.
Its AEC-Q101 qualification confirms robustness across −65 °C to +150 °C ambient, while thermal resistance Rth(j-a) = 500 K/W (SOT23, FR4 PCB) supports stable operation under continuous 100 mA output current at moderate ambient temperatures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V automotive and industrial supply rails with margin. |
| IO | 100 mA - Continuous output current capability; sufficient for driving LEDs, small relays, MOSFET gates, or logic inputs. |
| R1 | 10 kΩ (7–13 kΩ range) - Input bias resistor value; sets base current when driven by 3.3 V or 5 V logic, eliminating external resistor placement. |
| R2/R1 | 1.0 (0.8–1.2) - Matched internal resistor ratio; ensures stable saturation and predictable turn-off behavior across process variation. |
| VCE(sat) | ≤150 mV at IC = 10 mA / IB = 0.5 mA - Low saturation voltage minimizes power loss and self-heating during switching. |
| hFE | ≥30 at VCE = 5 V, IC = 5 mA - Minimum DC current gain ensures reliable forced-beta switching without marginal biasing. |
| fT | 230 MHz - Transition frequency of the embedded transistor; supports fast digital switching up to ~10–20 MHz edge rates. |
Pinout & Package
PDTC114ET215 is housed in a standard SOT23 (TO-236AB) plastic surface-mounted package with 3 leads, body dimensions 3.0 × 1.4 × 1.1 mm, and tin-plated terminations compatible with lead-free reflow soldering only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | input (base) | Logic-level input node connected internally to R1; accepts 0–40 V positive drive, enabling direct interface with microcontrollers and gate drivers. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; serves as common reference for both input and output paths in low-side switching configurations. |
| 3 | output (collector) | Switched output node capable of sinking up to 100 mA; connects to load (e.g., LED anode, relay coil, or downstream IC input) referenced to VCC. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 + R2 bias network | Eliminates need for two external resistors, reducing BOM count, PCB area, and assembly cost in high-volume digital interface designs. |
| AEC-Q101 qualification | Validated for automotive-grade temperature cycling, humidity, and mechanical stress, supporting deployment in engine control, body electronics, and ADAS subsystems. |
| 100 mA continuous output rating | Supports direct drive of medium-current loads without heat-sinking, simplifying thermal design in compact modules like sensor interfaces and power sequencers. |
| SOT23 reflow-compatible footprint | Standardized 3-pin layout aligns with automated pick-and-place equipment and IPC-compliant reflow profiles, ensuring manufacturability at scale. |
| VI(off) = 0.8–1.1 V typical | Guaranteed turn-off threshold allows clean logic-level compatibility with 1.8 V, 3.3 V, and 5 V CMOS outputs without risk of partial conduction. |

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 |
|---|---|---|---|
| ON Semiconductor NSS12500UW3T2G | SOT323 package (smaller), R1 = 4.7 kΩ, R2 = 4.7 kΩ, VCEO = 50 V, IO = 100 mA | Higher input current due to lower R1; better suited for 1.8 V logic but less margin at 5 V drive | Select when board space is constrained and lower input impedance is acceptable for faster turn-on. |
| ROHM DTC114EKT146 | SOT23 package, identical R1/R2 values (10 kΩ/10 kΩ), same VCEO/IO, but not AEC-Q101 qualified | Lacks automotive qualification; suitable for commercial/industrial use only | Choose for cost-sensitive non-automotive applications where AEC-Q101 is not required. |
Compared with NSS12500UW3T2G and DTC114EKT146, PDTC114ET215 provides the optimal balance of automotive qualification, standardized SOT23 footprint, and matched 10 kΩ bias network-making it the preferred choice for production-grade automotive and industrial control designs requiring long-term supply stability and validated reliability.

FAQ
What is the maximum operating temperature for PDTC114ET215?
The PDTC114ET215 has a specified junction temperature limit of 150 °C and an ambient operating range of −65 °C to +150 °C. Its thermal resistance Rth(j-a) is 500 K/W on a standard FR4 PCB, meaning it can sustain 100 mA output current continuously at ambient temperatures up to approximately 100 °C before reaching thermal limits-provided adequate copper pour and airflow are present.
Is PDTC114ET215 pin-compatible with BC847B in SOT23 packages?
No, PDTC114ET215 is not pin-compatible with BC847B. While both use SOT23, PDTC114ET215 has Pin 1 = input (base), Pin 2 = GND (emitter), Pin 3 = output (collector); BC847B uses Pin 1 = emitter, Pin 2 = base, Pin 3 = collector. Direct substitution would require PCB redesign. PDTC114ET215 replaces BC847-based circuits functionally-not physically-by integrating bias resistors and simplifying drive requirements.
Does PDTC114ET215 support 1.8 V logic-level input drive?
Yes, PDTC114ET215 supports 1.8 V logic-level input drive. Its VI(on) is specified at 1.8 V (typical) with VCE = 0.3 V and IC = 10 mA, and VI(off) is 0.8–1.1 V, ensuring unambiguous turn-on and turn-off margins with 1.8 V CMOS outputs. The 10 kΩ R1 resistor draws only ~180 µA at 1.8 V, minimizing loading on low-power microcontrollers.
What is the marking code for PDTC114ET215 on the device body?
The marking code for PDTC114ET215 is *16, where the asterisk (*) is a placeholder for the manufacturing site code. This top-side laser marking appears on the SOT23 package and is used for traceability and identification during assembly and inspection-consistent with Nexperia's standard marking scheme for the PDTC114E series.
Can PDTC114ET215 be used in analog amplifier configurations?
No, PDTC114ET215 is not intended for linear analog amplifier use. Its integrated R1 and R2 resistors fix the base bias point, preventing external bias network customization required for stable Class-A or Class-AB amplification. It is optimized exclusively for digital switching applications-such as load control, logic interfacing, and level translation-where saturation and cutoff states dominate operation.
