Product details
Overview
PDTC114YTVL from Nexperia is a 50 V, 100 mA NPN resistor-equipped transistor (RET) in SOT23 package, featuring integrated R1 = 10 kΩ and R2 = 47 kΩ bias resistors. It functions as a single-chip digital switch for IC input control and load switching in industrial digital circuits, eliminating external base resistors.
For engineers reviewing the PDTC114YTVL datasheet, PDTC114YTVL pinout, PDTC114YTVL application, or PDTC114YTVL equivalent, this device offers verified DC current gain (hFE ≥ 100 at IC = 5 mA), low VCEsat (≤100 mV), and guaranteed VI(on)/VI(off) thresholds - critical for reliable logic-level interfacing and BOM simplification.
Technical Context
This RET integrates an NPN transistor with two precision on-chip resistors: R1 (input bias, 7–13 kΩ typ. 10 kΩ) connected between base and input, and R2 (base-emitter feedback, R2/R1 = 3.7–5.7 typ. 4.7) tied from base to emitter. The internal topology enables direct TTL/CMOS logic drive without external components.
It operates within −65 °C to +150 °C ambient range, supports up to 250 mW total power dissipation at Tamb ≤ 25 °C on FR4 PCB, and delivers fT = 230 MHz (typ.) for the intrinsic transistor - confirming suitability for high-speed digital switching below 10 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - maximum safe collector-emitter voltage under open-base condition; defines off-state blocking capability in switching applications. |
| IO | 100 mA - continuous output current rating; supports driving moderate loads like LEDs, small relays, or logic inputs. |
| R1 | 10 kΩ (7–13 kΩ) - input bias resistor value; sets base current for predictable turn-on with standard 3.3 V/5 V logic levels. |
| R2/R1 | 4.7 (3.7–5.7) - feedback resistor ratio; ensures stable saturation and prevents thermal runaway during conduction. |
| hFE | ≥100 - DC current gain at VCE = 5 V, IC = 5 mA; guarantees sufficient gain margin for reliable switching across temperature. |
| VCEsat | ≤100 mV - collector-emitter saturation voltage at IC = 5 mA, IB = 0.25 mA; minimizes power loss and heating in on-state. |
| fT | 230 MHz - transition frequency of internal transistor; confirms fast switching response suitable for <10 MHz digital signals. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch, FR4-compatible footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Logic-level signal input; connects to R1 and internal transistor base - accepts 0.5–40 V drive with built-in current limiting. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; serves as common return path and reference for R2 feedback network. |
| 3 | O (collector) | Switched output node; connects to load (e.g., LED anode or relay coil); sinks current when device is on. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in R1 + R2 bias network | Eliminates need for two external resistors - reduces PCB area by ~1.5 mm² and removes solder joint reliability risk. |
| 100 mA output current rating | Supports direct drive of industrial I/O loads (e.g., optocoupler inputs, small solenoids) without external amplification. |
| Guaranteed VI(on)/VI(off) thresholds | VI(on) ≤ 0.8 V (min) and VI(off) ≥ 0.7 V (typ.) enable robust noise immunity against 3.3 V/5 V logic transitions. |
| Thermal derating support | 500 K/W junction-to-ambient thermal resistance on standard FR4 allows sustained 100 mA operation up to +85 °C ambient. |
Applications
| Industrial Digital I/O Interface | Microcontroller GPIO Expander |
|---|---|
|
Use Scenario: Isolating and level-shifting microcontroller outputs to drive 24 V PLC inputs or sensor modules. IC Role / Device Role / Timing Role: NPN switch translating 3.3 V logic to 24 V sink interface with built-in current limiting.

IC Role / Device Role / Timing Role: Single-transistor load switch enabling MCU pins to drive LEDs, buzzers, or small relays directly. Use Value: Enables 100 mA per channel without external biasing - simplifies firmware design and eliminates resistor tolerance sensitivity. |
| Cost-Sensitive Consumer Electronics | Automated Test Equipment (ATE) Signal Conditioning |
|
Use Scenario: Power sequencing and enable control in battery-powered smart home devices where component count impacts cost and size. IC Role / Device Role / Timing Role: Low-voltage logic-controlled power gate for subsystems like display backlight or sensor bias rails. Use Value: Achieves 50 V breakdown and 100 mA drive in 1.3 mm wide SOT23 - saves >30% board space vs. discrete transistor+resistor solution. |
Use Scenario: Fast-response digital signal routing in ATE fixture boards requiring precise on/off timing and repeatable threshold behavior. IC Role / Device Role / Timing Role: High-reliability digital switch with 230 MHz fT and sub-100 ns turn-on/turn-off times. Use Value: Delivers consistent VI(on)/VI(off) across −40 °C to +100 °C - reduces calibration drift and improves test repeatability. |
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 |
|---|---|---|---|
| PDTC114ETVL | R1 = 10 kΩ, R2 = 10 kΩ (R2/R1 = 1.0); lower feedback ratio reduces saturation stability margin. | Better suited for low-current (<10 mA), high-gain logic buffering; less tolerant of temperature variation in switching loads. | Select when driving high-impedance CMOS inputs where minimal base current suffices and thermal stability is secondary. |
| MMBT3904LT1G | Discrete NPN BJT (no integrated resistors); requires external R1/R2; hFE = 100–300, VCEO = 40 V. | Offers wider hFE spread and higher fT (300 MHz), but increases BOM count and layout sensitivity to resistor placement. | Choose when fine-tuned biasing or higher speed (>10 MHz) is required, and design resources allow for discrete resistor optimization. |
Compared with PDTC114ETVL, PDTC114YTVL provides superior thermal stability due to its 4.7× R2/R1 ratio, while versus MMBT3904LT1G it trades minor speed reduction for significant BOM and layout simplification - making it optimal for cost-sensitive, volume-manufactured digital interfaces.

FAQ
What is the maximum input voltage allowed at the base (Pin 1) of PDTC114YTVL?
The absolute maximum input voltage (VI) is −6 V to +40 V, as specified in the Limiting Values table. This range accommodates both negative transient suppression and direct connection to 3.3 V, 5 V, or 24 V logic systems without external clamping diodes - provided current into Pin 1 remains limited by the internal R1 resistor.
Can PDTC114YTVL be used in linear amplifier configurations?
No - PDTC114YTVL is optimized for saturated switching operation only. Its integrated R1/R2 network fixes bias conditions for digital on/off behavior, and its hFE specification is given only at IC = 5 mA (not across a wide current range). Linear amplification requires externally adjustable bias and is not supported by this RET architecture.
How does the R2/R1 ratio affect switching performance?
A higher R2/R1 ratio (4.7 typ.) increases base-emitter feedback, improving saturation depth and thermal stability during sustained conduction. This reduces VCEsat drift over temperature and prevents unintended turn-off due to self-heating - critical for industrial loads operating continuously at 85 °C ambient.
Is PDTC114YTVL automotive-qualified?
No - per Nexperia's revision history and legal disclaimers, PDTC114YTVL is explicitly designated as non-automotive qualified. It is not tested to AEC-Q101 requirements. For automotive use, engineers must select the -Q qualified variant (e.g., PDTC114YT-Q) which undergoes extended reliability testing and qualification.
