Product details
Overview
PDTD113EUX from Nexperia is a 500 mA, 50 V NPN resistor-equipped transistor (RET) in SOT323 (SC-70) package, integrating 1 kΩ input bias resistor (R1) and 1 kΩ base-emitter resistor (R2) with ±10 % ratio tolerance. It functions as a digitally controlled switch in low-voltage logic interfaces, delivering 100 mV VCE(sat) at IC = 50 mA / IB = 2.5 mA and supporting automotive-grade operation up to 175 °C ambient.
For engineers reviewing the PDTD113EUX datasheet, PDTD113EUX pinout, PDTD113EUX application, or PDTD113EUX equivalent, key selection criteria include its built-in resistor network (R1 = R2 = 1 kΩ), AEC-Q101 qualification, 500 mA output capability, and compatibility with 3.3 V/5 V microcontroller GPIO drive without external bias components.
Technical Context
This RET integrates an NPN silicon transistor with two monolithically embedded thin-film resistors: R1 (base input) and R2 (base-emitter feedback), enabling single-resistor digital input control. Its internal structure eliminates discrete biasing components while maintaining DC current gain (hFE) ≥33 at IC = 50 mA and VCE = 5 V.
The device operates across −55 °C to +175 °C ambient, with thermal resistance Rth(j-a) = 353 K/W on 4-layer FR4 PCB. It supports fast switching via 225 MHz fT and exhibits low collector capacitance (Cc = 7 pF at VCB = 10 V), making it suitable for high-frequency digital load switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage before breakdown; enables use in 24 V industrial control rails. |
| IO | 500 mA - Continuous output current rating; supports driving relays, LEDs, or small solenoids directly. |
| R1 / R2 | 1 kΩ / 1 kΩ - Precise integrated bias network; eliminates external resistors and reduces BOM count by two parts. |
| VCE(sat) | 100 mV @ IC=50 mA - Low saturation voltage minimizes power loss and self-heating in high-duty-cycle switching. |
| hFE | ≥33 @ IC=50 mA - Sufficient DC gain to ensure reliable saturation with standard MCU GPIO drive strength. |
| fT | 225 MHz - High transition frequency supports clean edge integrity in >1 MHz digital switching applications. |
| AEC-Q101 | Qualified - Meets automotive stress test requirements for temperature cycling, HTRB, and ESD, enabling under-hood use. |
Pinout & Package
SOT323 (SC-70) plastic surface-mounted package: 1.3 mm × 1.8 mm footprint, 0.95 mm height, 3-terminal lead frame with gull-wing leads. Optimized for reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connects to digital control signal; internal R1 pulls this node to VCC when active, enabling direct MCU GPIO interface. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; serves as common reference for both input and output paths. |
| 3 | Output (collector) | Switched high-side or low-side load connection point; rated for 500 mA continuous current and 50 V blocking. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1/R2 bias network | Eliminates two external resistors, reducing PCB area and assembly cost in high-volume digital switch designs. |
| AEC-Q101 qualification | Validated for automotive under-hood environments including temperature cycling, humidity, and mechanical shock. |
| 175 °C maximum junction temperature | Enables deployment in engine control units, powertrain modules, and industrial motor drives without derating. |
| ±10 % R2/R1 ratio tolerance | Ensures consistent turn-on/off thresholds across production lots, improving batch-to-batch reliability in automated systems. |
| Low VCE(sat) (100 mV) | Reduces conduction losses below 5 mW at 50 mA, critical for thermally constrained space-constrained applications. |
Applications
| Automotive Body Control Module | Industrial PLC Digital Output |

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 |
|---|---|---|---|
| BC847BW | Discrete NPN BJT without integrated resistors; requires external RB and RBE. | Higher BOM count and layout complexity; no AEC-Q101 qualification. | Select when fine-tuned biasing or higher hFE (>110) is required, and automotive qualification is not mandatory. |
| PDTA114EU | PNP complement with identical R1/R2 values (10 kΩ/10 kΩ); same SOT323 package and AEC-Q101 rating. | Used for high-side switching where load connects to VCC, not ground. | Choose for complementary high-side driver pairing in H-bridge or dual-rail logic interface designs. |
Compared with BC847BW, PDTD113EUX reduces component count and qualifies for automotive use; compared with PDTA114EU, it provides NPN low-side switching with matched resistor values optimized for 3.3 V/5 V logic drive.

FAQ
What is the maximum operating temperature for PDTD113EUX?
PDTD113EUX has a maximum junction temperature of 175 °C and operates over an ambient range of −55 °C to +175 °C. Its thermal resistance is 353 K/W on a 4-layer FR4 PCB, enabling reliable performance in under-hood automotive environments and high-temperature industrial enclosures without forced cooling.
Can PDTD113EUX replace BC817 in existing designs?
Yes - PDTD113EUX serves as a drop-in functional replacement for BC817 in digital switching applications, offering identical voltage/current ratings plus integrated bias resistors. No circuit modification is needed beyond removing the two external base resistors, reducing layout area and assembly steps.
What is the meaning of 'EUX' in the part number PDTD113EUX?
The 'EUX' suffix denotes the SOT323 (SC-70) package variant with tape-and-reel packaging, RoHS-compliant finish, and standard marking code 'ZP'. It distinguishes this version from other packages (e.g., 'Z' for SOT23) and confirms AEC-Q101 qualification per Nexperia's ordering nomenclature.
How does the built-in resistor ratio affect switching behavior?
With R1 = R2 = 1 kΩ (R2/R1 = 1.0 ±10 %), PDTD113EUX ensures predictable VI(on) ≈ 1.4 V and VI(off) ≈ 1.1 V, providing robust noise immunity against 3.3 V logic signals. This ratio guarantees full saturation at IC/IB ≥20 while maintaining guaranteed turn-off even with leakage currents up to 0.8 mA.
