Product details
Overview
PDTD113ZK,115 from Nexperia is a 50 V, 500 mA NPN resistor-equipped transistor (RET) in SOT23 package, featuring integrated bias resistors R1 = 1 kΩ and R2 = 10 kΩ with ±10 % ratio tolerance. It functions as a digital switch for IC input control and load switching in industrial and automotive electronics.
For engineers reviewing the PDTD113ZK,115 datasheet, PDTD113ZK,115 pinout, PDTD113ZK,115 application, or PDTD113ZK,115 equivalent, key selection criteria include output current capability (500 mA), collector-emitter saturation voltage (≤300 mV at IC = 50 mA/IB = 2.5 mA), input voltage thresholds (VI(on): 0.4–1.4 V; VI(off): 0.3–1 V), and SOT23 footprint compatibility.
Technical Context
This NPN RET integrates two precision bias resistors to eliminate external base components, enabling direct logic-level drive without discrete pull-up/down networks. Its internal R1–R2 network sets fixed current gain behavior and ensures stable turn-on/turn-off thresholds across temperature (−40 °C to 100 °C).
The device operates within absolute maximum ratings of VCEO = 50 V, VEBO = 5 V, and Ptot = 250 mW on FR4 PCB. Its thermal resistance Rth(j-a) is 500 K/W, supporting reliable operation up to junction temperature Tj = 150 °C under defined mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage with open base; defines upper rail limit for switching applications. |
| IO | 500 mA - Continuous DC output current capability; supports medium-power loads like relays or LED strings. |
| R1 | 1 kΩ (±30 %) - Input bias resistor value; sets base current magnitude when driven from logic sources. |
| R2/R1 | 10 (9–11) - Fixed resistor ratio determining feedback and turn-off stability; enables predictable hysteresis-free switching. |
| VCEsat | ≤300 mV at IC = 50 mA / IB = 2.5 mA - Low saturation voltage minimizes conduction loss and self-heating during on-state. |
| VI(on) | 0.4–1.4 V at VCE = 0.3 V - On-threshold range compatible with 1.8 V, 3.3 V, and 5 V logic families without level shifting. |
| VI(off) | 0.3–1 V at VCE = 5 V - Off-threshold ensures robust noise immunity and prevents false triggering near ground. |
Pinout & Package
SOT23 plastic surface-mounted package: 3-terminal, 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pitch, standard footprint per Fig. 6 (reflow) and Fig. 7 (wave) in Nexperia documentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (I) | Input (base node) | Connected internally to R1; accepts logic-level drive; no external base resistor required. |
| 2 (GND) | Ground (emitter node) | Emitter terminal tied to system ground; provides return path for load current and bias network. |
| 3 (O) | Output (collector node) | Switched high-side output; connects to load anode or VCC-side of controlled circuit. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in R1/R2 bias network | Eliminates two external resistors, reducing BOM count and PCB area in digital interface circuits. |
| 500 mA continuous output | Supports direct driving of moderate-current loads such as optocouplers, small solenoids, or logic buffers. |
| ±10 % R2/R1 ratio tolerance | Ensures consistent switching thresholds and predictable gain across production lots and temperature. |
| Low VCEsat (≤300 mV) | Reduces power dissipation during conduction, enabling higher duty-cycle operation without thermal derating. |
| SOT23 footprint compatibility | Enables drop-in replacement for BC817-series transistors in existing layouts with minimal redesign effort. |

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 |
|---|---|---|---|
| BC817-40,115 | Discrete NPN BJT without built-in resistors; requires external base bias network (R1 + R2). | Higher component count and layout complexity; less suitable for space-constrained or high-volume automated assembly. | Select when design requires adjustable gain or custom threshold tuning not possible with fixed-R1/R2 RETs. |
| PDTB113ZK,115 | PNP complement with identical R1/R2 values and SOT23 package; VCEO = 50 V, IO = 500 mA. | Used for high-side switching where emitter connects to VCC; polarity reversal changes control logic (active-low vs active-high). | Choose for complementary push-pull output stages or inverted signal paths requiring matched RET characteristics. |

FAQ
What is the function of the internal resistors in PDTD113ZK,115?
The PDTD113ZK,115 integrates R1 = 1 kΩ (input resistor) and R2 = 10 kΩ (feedback resistor) to form a self-biasing network that replaces external base components. This allows direct connection to logic outputs without additional resistors, ensuring predictable turn-on and turn-off behavior while reducing PCB area and assembly steps. The R2/R1 ratio of 10 provides stable current gain and noise immunity.
Can PDTD113ZK,115 replace BC817 series transistors directly?
Yes, PDTD113ZK,115 serves as a cost-saving alternative to BC817-series transistors in digital switching applications, as confirmed in Nexperia's official datasheet. Its SOT23 footprint matches BC817 packages, and its 500 mA rating meets or exceeds BC817-40 performance. However, unlike BC817, PDTD113ZK,115 includes built-in bias resistors-so external base resistors must be omitted in the layout to avoid double-biasing.
What is the maximum ambient temperature for continuous operation of PDTD113ZK,115?
The PDTD113ZK,115 supports continuous operation from −65 °C to +150 °C ambient temperature, per its limiting values table. At Tamb = 25 °C, total power dissipation is rated at 250 mW on FR4 PCB with single-sided copper. Derating is required above 25 °C using the specified Rth(j-a) = 500 K/W to maintain junction temperature ≤150 °C.
Is PDTD113ZK,115 qualified for automotive applications?
No, PDTD113ZK,115 is not automotive-qualified. According to Nexperia's revision history (v.4, Jan 2023), this part was explicitly changed to non-automotive qualification status. For automotive use, Nexperia offers Q-qualified variants (e.g., PDTD113ZQ series); PDTD113ZK,115 should only be used in industrial, consumer, or commercial applications where AEC-Q101 stress testing is not required.
How does the VI(on) specification affect microcontroller interfacing with PDTD113ZK,115?
The VI(on) range of 0.4–1.4 V at VCE = 0.3 V means PDTD113ZK,115 reliably turns on when driven by 1.8 V, 3.3 V, or 5 V logic outputs-even with voltage drops across series resistors or PCB traces. This wide threshold ensures compatibility with diverse MCUs and eliminates need for level shifters, while maintaining noise margin against ground bounce or crosstalk in mixed-signal systems.
