Product details
Overview
PDTD113ZT from Nexperia is a 50 V, 500 mA NPN resistor-equipped transistor (RET) in SOT23 package, integrating 1 kΩ input bias resistor (R1) and 10 kΩ feedback resistor (R2) for direct digital logic interfacing. It functions as a single-chip switch for controlling IC inputs or driving small loads in automotive and industrial digital circuits, eliminating external base resistors.
For engineers reviewing the PDTD113ZT datasheet, PDTD113ZT pinout, PDTD113ZT application, or PDTD113ZT equivalent, this device serves as a drop-in replacement for BC817-based switching stages where simplified layout, reduced BOM count, and guaranteed R2/R1 ratio tolerance (±10 %) are critical selection criteria.
Technical Context
This RET integrates two precision thin-film resistors on-die: R1 (1 kΩ, ±30 %) connects base to input, and R2 (10 kΩ, ±30 %) connects base to emitter, forming a fixed-current-bias network. Its internal topology enables direct TTL/CMOS-level drive without external components.
The device operates with guaranteed DC current gain (hFE ≥ 70 at IC = 50 mA, VCE = 5 V) and low saturation voltage (VCEsat ≤ 300 mV at IC = 50 mA, IB = 2.5 mA), supporting reliable on/off switching in load-control and signal-gating roles across −40 °C to +150 °C ambient range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports 24 V industrial bus switching with margin. |
| IO | 500 mA - Continuous output current rating; suitable for driving relays, LEDs, or logic inputs with headroom. |
| R1 | 1 kΩ (0.7–1.3 kΩ) - Input bias resistor value; sets base current when driven by 3.3 V or 5 V logic. |
| R2/R1 | 10 (9–11) - Fixed feedback-to-input resistor ratio; ensures stable bias point and predictable turn-on threshold. |
| VCEsat | ≤ 300 mV at IC = 50 mA - Low saturation voltage minimizes power loss and heat generation in switching mode. |
| hFE | ≥ 70 at IC = 50 mA - Minimum DC current gain guarantees sufficient drive capability for downstream loads. |
| VI(on) | 0.4–1.4 V at IC = 20 mA - On-state input voltage range defines compatible logic families (e.g., TTL, CMOS). |
Pinout & Package
Package: SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch), optimized for automated assembly and thermal performance on FR4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connects to digital control signal; internally tied to R1 and R2 junction. |
| 2 | Ground (emitter) | Emitter terminal and reference node for R2; must be connected to system ground. |
| 3 | Output (collector) | Switched output node; drives load between collector and positive supply rail. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in bias resistors | Eliminates need for two external SMD resistors, reducing PCB area and assembly steps. |
| ±10 % R2/R1 ratio tolerance | Ensures consistent turn-on behavior across production lots, improving batch-to-batch reliability. |
| 500 mA output current capability | Supports direct switching of medium-current loads like optocouplers, small solenoids, or LED strings. |
| SOT23 footprint compatibility | Enables drop-in replacement for standard transistors (e.g., BC817) without layout redesign. |
Applications
| Automotive Body Control Module | Industrial PLC Digital Output Stage |

IC Role / Device Role / Timing Role: Low-side switch controlled by MCU to gate power to subsystems based on state machine logic. Use Value: 500 mA rating and 300 mV VCEsat minimize voltage drop and self-heating during sustained conduction. |
Use Scenario: Managing battery-powered peripheral sensors (e.g., temperature, motion) by enabling only active units. IC Role / Device Role / Timing Role: Energy-efficient load switch that minimizes quiescent current (ICEO ≤ 0.5 µA) in off-state. Use Value: VI(off) ≤ 1 V ensures full cutoff with 1.8 V or 3.3 V MCU outputs, extending battery life. |
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 R1/R2; no integrated resistors; hFE = 250–600 (wider spread). | Requires PCB space and assembly for two 0402 resistors; less predictable bias point due to resistor tolerance stacking. | Select when higher hFE or adjustable bias ratio is required; not recommended for high-volume, cost-sensitive designs. |
| PDTB113ZT,215 | PNP complement with identical R1/R2 values and package; VCEO = −50 V; IO = −500 mA. | Used in high-side switching configurations where load connects to ground and source connects to supply. | Select for complementary high-side drive in push-pull or H-bridge topologies requiring matched RET characteristics. |
Compared with BC817-40 and PDTB113ZT, PDTD113ZT uniquely delivers integrated biasing with guaranteed ratio tolerance and SOT23 footprint-reducing component count by two per channel while maintaining 500 mA drive and 50 V blocking capability.

FAQ
What is the maximum continuous collector current for PDTD113ZT?
The absolute maximum continuous collector current is 500 mA, as specified in the Limiting Values table under "IO output current." This rating applies at Tamb ≤ 25 °C with proper PCB thermal relief; derating is required above 25 °C ambient per the thermal resistance (Rth(j-a) = 500 K/W) and power dissipation limit (Ptot = 250 mW).
Can PDTD113ZT be used with 1.8 V logic inputs?
Yes - VI(on) ranges from 0.4 V to 1.4 V at IC = 20 mA, meaning it reliably turns on with 1.8 V logic signals. VI(off) ≤ 1 V ensures full cutoff when the input is at 0 V or near-ground, making it compatible with 1.8 V, 3.3 V, and 5 V digital interfaces without level-shifting circuitry.
How does the R2/R1 ratio affect switching behavior?
The R2/R1 ratio of 10 (9–11) sets the internal feedback that stabilizes the base-emitter voltage and defines the effective current gain. A tighter ratio tolerance ensures consistent turn-on voltage (VI(on)) and reduces variation in saturation voltage (VCEsat) across temperature and process corners, improving predictability in mass-produced systems.
Is PDTD113ZT qualified for automotive applications?
No - the January 2023 datasheet explicitly states this part was changed to non-automotive qualification. For automotive use, Nexperia offers the -Q qualified variant (e.g., PDTD113ZT-Q), which undergoes AEC-Q101 stress testing and is documented separately on nexperia.com.
