Product details
Overview
PDTD113ZS,126 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 PDTD113ZS,126 datasheet, PDTD113ZS,126 pinout, PDTD113ZS,126 application, or PDTD113ZS,126 equivalent, key selection criteria include output current capability (500 mA), collector-emitter saturation voltage (≤300 mV at IC = 50 mA/IB = 2.5 mA), off-state input voltage (0.3–1.0 V), on-state input voltage (0.4–1.4 V), and SOT23 footprint compatibility.
Technical Context
This NPN RET integrates two precision bias resistors to eliminate external base drive components, enabling direct logic-level interfacing without discrete resistors. Its internal R1–R2 network sets fixed current gain behavior and ensures predictable turn-on/turn-off thresholds across temperature (−40 °C to 100 °C).
The device operates within a 50 V VCEO rating and delivers 500 mA continuous output current while maintaining low VCEsat (≤300 mV) and tight VI(on)/VI(off) windows-critical for reliable digital switching in noise-prone environments such as engine control modules and PLC I/O stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage under open-base conditions; defines system rail compatibility up to 48 V DC applications. |
| IO | 500 mA - Continuous output current rating; supports driving medium-power relays, LEDs, or logic inputs without external current boosting. |
| R1 | 1 kΩ (±30 %) - Input bias resistor value; sets base current magnitude when driven from standard CMOS/TTL outputs. |
| R2/R1 | 10 (9–11) - Fixed resistor ratio determining internal feedback and saturation stability; enables consistent switching behavior across production lots. |
| VCEsat | ≤300 mV at IC = 50 mA / IB = 2.5 mA - Low saturation voltage minimizes power loss and self-heating during active conduction. |
| VI(on) | 0.4–1.4 V at VCE = 0.3 V - Guaranteed turn-on threshold range ensures compatibility with 1.8 V, 3.3 V, and 5 V logic families. |
| VI(off) | 0.3–1.0 V at VCE = 5 V - Defined turn-off window prevents false triggering from noise or leakage in high-impedance nodes. |
Pinout & Package
SOT23 plastic surface-mounted package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pitch); thermally rated for 250 mW at Tamb ≤ 25 °C on FR4 PCB with single-sided copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (I) | Input (base node) | Internal connection to R1; accepts logic-level drive directly-no external base resistor required. |
| 2 (GND) | Ground (emitter) | Emitter terminal tied to system ground; serves as common reference for input and output paths. |
| 3 (O) | Output (collector) | Switched high-side output node; connects to load (e.g., relay coil, LED anode) referenced to positive supply. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in bias resistors R1 + R2 | Eliminates two external SMT resistors per switch channel, reducing BOM count and PCB area by ~1.5 mm² per instance. |
| 500 mA output current rating | Supports direct drive of industrial solenoids (≤24 V/200 mA), optocoupler LEDs, and microcontroller GPIO protection circuits. |
| ±10 % R2/R1 tolerance | Ensures repeatable hFE-dependent switching thresholds across temperature and process variation-critical for deterministic timing in control logic. |
| Low VCEsat (≤300 mV) | Reduces conduction loss to <15 mW at 50 mA, enabling use in thermally constrained modules without heatsinking. |
| SOT23 footprint compatibility | Enables drop-in replacement for BC817-40 and similar general-purpose transistors using existing pick-and-place programs and stencil apertures. |
Applications
| Automotive Body Control Module | Industrial PLC Digital Output Stage |

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 |
|---|---|---|---|
| BC817-40,215 | Discrete NPN transistor requiring external base resistors; no built-in R1/R2 network; hFE = 250–630 (wider spread). | Higher design effort for biasing; less predictable VI(on)/VI(off); requires additional PCB area and assembly steps. | Select when fine-tuned gain control or higher VCEO (45 V) is needed, and board space allows for two extra 0402 resistors. |
| PDTB113ZT,115 | PNP complement with identical R1/R2 values and SOT23 package; VCEO = 50 V, IO = 500 mA, but polarity inverted. | Used for high-side switching or complementary push-pull stages-not interchangeable without circuit redesign. | Select only for PNP-side switching where sourcing current from supply rail is required, e.g., in dual-rail interface buffers. |
Compared with BC817-40,215 and PDTB113ZT,115, the PDTD113ZS,126 provides guaranteed biasing, reduced layout complexity, and tighter input threshold control-making it optimal for cost-sensitive, high-volume digital switching where consistency and assembly efficiency are prioritized over adjustable gain.

FAQ
What is the maximum continuous collector current rating for PDTD113ZS,126?
The PDTD113ZS,126 is rated for 500 mA continuous output current under standard mounting conditions (FR4 PCB, single-sided copper). This rating applies at ambient temperatures up to 25 °C; derating is required above that per the thermal resistance curve in the datasheet. The device maintains this capability while holding VCEsat ≤300 mV at IC = 50 mA/IB = 2.5 mA, confirming robust conduction performance for PDTD113ZS,126 in real-world switching loads.
Does PDTD113ZS,126 require external base resistors?
No, PDTD113ZS,126 integrates R1 = 1 kΩ and R2 = 10 kΩ internally, eliminating the need for external base bias resistors. This built-in network establishes a fixed current gain path and defines precise VI(on) and VI(off) thresholds-enabling direct connection to 1.8 V, 3.3 V, or 5 V logic outputs without additional components. The design simplifies layout and improves repeatability versus discrete BJT implementations like BC817 with external resistors.
What is the package type and dimensions of PDTD113ZS,126?
PDTD113ZS,126 uses the SOT23 surface-mount package measuring 2.9 mm × 1.3 mm × 1.0 mm with 1.9 mm lead pitch. Its standardized outline matches JEDEC TO-236AB, ensuring compatibility with automated placement equipment and reflow soldering profiles defined in Nexperia's application notes. The compact size supports high-density routing in space-constrained applications such as automotive ECUs and smart sensor nodes using PDTD113ZS,126.
Is PDTD113ZS,126 qualified for automotive applications?
No, PDTD113ZS,126 is not automotive-qualified. According to Nexperia's revision history, this part was explicitly changed to non-automotive qualification status in the January 2023 datasheet update. For automotive-grade equivalents, designers must select variants marked with "-Q" suffix (e.g., PDTD113ZT-Q) which undergo AEC-Q101 stress testing. PDTD113ZS,126 remains suitable for industrial and consumer applications where full automotive qualification is not mandated.
What are the typical input voltage thresholds for turning PDTD113ZS,126 on and off?
PDTD113ZS,126 has a typical on-state input voltage (VI(on)) of 0.8 V and off-state input voltage (VI(off)) of 0.6 V, both specified at Tamb = 25 °C. The full operating ranges are VI(on) = 0.4–1.4 V (at VCE = 0.3 V, IC = 20 mA) and VI(off) = 0.3–1.0 V (at VCE = 5 V, IC = 100 µA). These tightly bounded thresholds ensure reliable switching with common logic families and reduce susceptibility to noise-induced misfiring in PDTD113ZS,126 deployments.
