Product details
Overview
PDTD114EUF from Nexperia is a 500 mA, 50 V NPN resistor-equipped transistor (RET) in SOT323 (SC-70) package, integrating 10 kΩ input bias resistor (R1) and 10 kΩ base-emitter resistor (R2) with ±10% ratio tolerance. It functions as a digitally controlled switch in low-voltage logic interfaces, supports AEC-Q101 automotive qualification, and operates up to 175 °C ambient temperature.
For engineers reviewing the PDTD114EUF datasheet, PDTD114EUF pinout, PDTD114EUF application, or PDTD114EUF equivalent, key selection criteria include its 10 kΩ/10 kΩ resistor configuration, 70 minimum DC current gain at 50 mA, 100 mV max VCE(sat), and compatibility with 50 V collector-emitter voltage switching in space-constrained automotive and industrial control circuits.
Technical Context
This RET integrates two precision thin-film resistors directly on-die: R1 (10 kΩ) connects input to base, and R2 (10 kΩ) shunts base to emitter, enabling single-resistor digital drive without external bias components. Its internal NPN transistor delivers hFE ≥ 70 at IC = 50 mA and VCE = 5 V.
The device meets AEC-Q101 stress test requirements for discrete semiconductors and supports operation from −55 °C to +175 °C junction temperature. Thermal resistance is 353 K/W (4-layer PCB) and 500 K/W (single-sided FR4), with 300 mW total power dissipation at 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage before breakdown; enables use in 24 V and 36 V automotive supply rails. |
| IO | 500 mA - Continuous output current capability; sufficient for driving relays, LEDs, and small solenoids. |
| R1 / R2 | 10 kΩ / 10 kΩ - Fixed internal bias network; eliminates need for external base resistors in digital logic interfacing. |
| hFE | ≥ 70 at IC = 50 mA - Ensures reliable saturation with low drive current (e.g., 0.7 mA base current suffices for 50 mA collector load). |
| VCE(sat) | ≤ 100 mV at IC = 50 mA, IB = 2.5 mA - Minimizes conduction loss and self-heating in high-duty-cycle switching. |
| Tj(max) | 175 °C - Enables deployment in under-hood automotive modules and industrial motor controllers without derating. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including HTOL, TC, HAST, and ESD testing per JESD22 standards. |
Pinout & Package
SOT323 (SC-70) plastic surface-mounted package: 1.35 mm × 1.15 mm × 0.45 mm body, 3-terminal leadframe, tin-plated terminations compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base via R1) | Logic-level input node; accepts 0–50 V drive; internal 10 kΩ resistor limits base current automatically. |
| 2 | GND (emitter) | Emitter reference and return path; must be connected to system ground or low-side return for proper biasing. |
| 3 | Output (collector) | Switched high-side load connection; rated for 50 V and 500 mA continuous; requires external flyback protection for inductive loads. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | 10 kΩ R1 + 10 kΩ R2 eliminates 2 external resistors, reducing BOM count and PCB area in digital interface designs. |
| AEC-Q101 qualification | Validated for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. |
| High-temperature operation | Rated for continuous operation up to +175 °C junction temperature-suitable for under-hood and industrial environments. |
| Low VCE(sat) | 100 mV max ensures <10 mW conduction loss at 100 mA load, minimizing thermal stress in compact layouts. |
| ±10% R2/R1 ratio tolerance | Ensures consistent turn-on threshold across production lots, critical for deterministic logic-level switching behavior. |
Applications

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 |
|---|---|---|---|
| PDTB114EU | PNP complement with identical R1/R2 values (10 kΩ/10 kΩ), same SOT323 package, but inverted polarity. | Used in high-side switching where load connects to VCC instead of ground; requires inverted logic drive. | Select when sourcing current from supply rail is required, e.g., LED anode switching or PMOS gate pull-up. |
| BC807-40 | Standard NPN BJT without built-in resistors; requires two external bias resistors; hFE = 250–630 (wider spread); no AEC-Q101 qualification. | Offers higher gain and lower VCE(sat) (~70 mV), but increases component count and lacks automotive qualification. | Choose only for non-automotive, cost-sensitive designs where board space and qualification are not constraints. |
Compared with PDTB114EU, PDTD114EUF provides complementary NPN functionality for low-side switching, while BC807-40 demands external biasing and lacks automotive validation-making PDTD114EUF optimal for space-constrained, qualified automotive and industrial control nodes.

FAQ
What is the maximum input voltage the PDTD114EUF can tolerate at Pin 1?
The absolute maximum input voltage at Pin 1 (input) is +50 V, as specified in the VI input voltage limiting values table. This rating applies with the emitter grounded and ensures safe operation when interfacing with 24 V or 36 V automotive systems without external clamping diodes.
Does PDTD114EUF require external base resistors?
No. PDTD114EUF integrates both R1 (10 kΩ) and R2 (10 kΩ) internally, eliminating the need for external base bias resistors. This simplifies design, reduces PCB area, and improves consistency across production units compared to discrete BJT + resistor solutions.
Can PDTD114EUF drive inductive loads like relays directly?
Yes, but only with external flyback protection. The device supports 500 mA continuous collector current and 50 V VCEO, making it suitable for relay coils up to ~12 V/400 mA. A reverse-biased diode (e.g., 1N4148) must be placed across the coil to suppress inductive kickback and prevent collector-emitter breakdown.
How does the R2/R1 ratio affect switching behavior?
With R2/R1 = 1.0 ± 0.1, the PDTD114EUF ensures predictable turn-on and turn-off thresholds. A unity ratio provides balanced biasing that maintains stable saturation even with process variation, enabling robust digital switching without oscillation or partial turn-on in noisy environments.
