Product details
Overview
PDTD113ZT-QR from Nexperia is an NPN resistor-equipped transistor (RET) in SOT23 package, designed for digital switching in automotive and industrial control circuits. It integrates 1 kΩ input bias resistor (R1) and 10 kΩ feedback resistor (R2), delivers 500 mA output current, supports 50 V collector-emitter voltage, and features ±10 % R2/R1 ratio tolerance.
For engineers reviewing the PDTD113ZT-QR datasheet, PDTD113ZT-QR pinout, PDTD113ZT-QR application, or PDTD113ZT-QR equivalent, key selection criteria include built-in bias network compatibility with 3.3 V/5 V logic interfaces, AEC-Q101 qualification for under-hood use, thermal resistance (500 K/W), and direct replacement capability for BC817-based digital switch designs.
Technical Context
This RET functions as a single-transistor logic-level switch with integrated base biasing, eliminating external resistors in saturated-switch applications. Its fixed R1–R2 network sets input threshold and ensures stable turn-on/turn-off behavior across −40 °C to +150 °C ambient range.
The device operates in active or saturation mode depending on applied input voltage: VI(on) ranges from 0.4 V to 1.4 V at IC = 20 mA, while VI(off) stays below 1 V at IC ≤ 100 µA - enabling robust noise margin in noisy automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage before breakdown; enables use in 24 V automotive power domains with margin. |
| IO | 500 mA - Continuous DC output current capability; sufficient for driving relays, LEDs, or small solenoids directly. |
| R1 | 1 kΩ (0.7–1.3 kΩ) - Input bias resistor value; sets base current when driven by standard CMOS/TTL logic outputs. |
| R2/R1 ratio | 10 ±10 % - Feedback-to-input resistor ratio; determines gain stability and saturation depth under temperature variation. |
| VCE(sat) | ≤300 mV at IC = 50 mA, IB = 2.5 mA - Low saturation voltage minimizes conduction loss and self-heating in high-duty-cycle switching. |
| Ptot | 250 mW at Tamb ≤ 25 °C - Total power dissipation limit on FR4 PCB; defines maximum continuous switching frequency at given load. |
| hFE | ≥70 at VCE = 5 V, IC = 50 mA - Minimum DC current gain ensures reliable saturation with low drive current. |
Pinout & Package
Package: SOT23 plastic surface-mount package, 3-terminal, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connects to logic signal source; internal node between R1 and R2; requires no external pull-up/down. |
| 2 | Ground (emitter) | Common reference terminal for input and output paths; must be tied to system ground plane for proper biasing. |
| 3 | Output (collector) | Switched high-side or low-side load connection point; rated for 50 V and 500 mA continuous DC current. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in R1–R2 bias network | Eliminates two external resistors per switch channel, reducing BOM count and PCB area in multi-channel control modules. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for engine control, lighting, and body electronics. |
| ±10 % R2/R1 tolerance | Ensures consistent switching thresholds across production lots and temperature extremes, critical for deterministic timing in safety-related subsystems. |
| Low VCE(sat) | ≤300 mV enables <150 mW conduction loss at 500 mA, supporting thermally constrained layouts in sealed enclosures or stacked modules. |
Applications
| Automotive Lighting Control | Industrial PLC Digital Output |
|---|---|
Use Scenario: Switching LED headlamp modules and interior ambient lighting in vehicle body control units. IC Role / Device Role / Timing Role: NPN RET acts as low-side driver for constant-current LED strings, accepting PWM signals from microcontroller GPIO. Use Value: Integrated biasing eliminates discrete resistor placement errors; AEC-Q101 rating ensures operation at 125 °C junction temperature under hood. |
Use Scenario: Driving 24 V DC solenoid valves and indicator lamps in programmable logic controller output modules. IC Role / Device Role / Timing Role: Logic-level interface between isolated microcontroller outputs and industrial loads requiring up to 500 mA sink current. Use Value: 50 V VCEO withstands inductive kickback; 250 mW power rating allows sustained duty cycles without heatsinking. |
| Automotive HVAC Blower Control | Consumer Appliance Motor Interface |
Use Scenario: Controlling brushed DC blower motors in climate control systems using pulse-width modulated enable signals. IC Role / Device Role / Timing Role: High-current saturated switch interfacing MCU PWM outputs to motor driver FET gates or motor windings directly. Use Value: 500 mA output current supports gate charging of downstream MOSFETs; low VCE(sat) reduces heat generation during continuous PWM operation. |
Use Scenario: Replacing BC817 transistors in washing machine control boards to drive buzzer, display backlight, and valve actuators. IC Role / Device Role / Timing Role: Cost-optimized digital switch replacing discrete transistor + resistor combinations in white goods mainboards. Use Value: Identical SOT23 footprint enables drop-in replacement; reduced pick-and-place steps lower manufacturing cost by ~12 % per channel. |
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 | No integrated resistors; requires external RB and RBE; hFE = 250–630; VCEO = 45 V. | Higher gain but no built-in biasing; less suitable for space-constrained automotive modules. | Select when precise gain tuning or higher hFE is required; add 2 resistors and verify layout clearance. |
| PDTB113ZT | PNP complement; same R1/R2 values and AEC-Q101 rating; VCEO = −50 V; IO = −500 mA. | Used for high-side switching or complementary push-pull stages where sourcing current is needed. | Choose for bidirectional load control or when matching PNP/NPN pairs in differential sensing circuits. |
Compared with BC817-40, PDTD113ZT-QR reduces component count and improves thermal consistency; versus PDTB113ZT, it provides NPN polarity for standard low-side switching - making it optimal for logic-driven sink applications in automotive ECUs.

FAQ
What is the maximum operating temperature for PDTD113ZT-QR?
The junction temperature (Tj) is rated up to 150 °C, and ambient temperature (Tamb) spans −65 °C to +150 °C. When mounted on FR4 PCB with standard footprint, thermal resistance is 500 K/W - meaning at 250 mW dissipation, junction rise is 125 K above ambient, limiting continuous operation to ≤25 °C ambient unless heatsinking is added.
Can PDTD113ZT-QR replace BC817 in existing designs?
Yes - it shares the SOT23 footprint and pinout (input/base, emitter/GND, collector/output), and its integrated R1/R2 network simplifies layout. However, VI(on) and VI(off) thresholds differ slightly; verify logic-high voltage compatibility (≥0.8 V typical) and ensure no unintended turn-on from noise coupling due to lower input impedance.
Is PDTD113ZT-QR suitable for PWM switching applications?
Yes - with VCE(sat) ≤300 mV and hFE ≥70, it achieves fast saturation and low conduction loss. Switching speed is limited by Cc = 7 pF and internal resistor network time constants; verified operation up to 100 kHz PWM at 50 % duty cycle with appropriate gate drive strength and load decoupling.
Does PDTD113ZT-QR require external protection diodes when driving inductive loads?
Yes - although rated for 50 V VCEO, inductive kickback can exceed this during turn-off. A flyback diode (e.g., BAS216) must be placed across the load (anode to GND, cathode to collector) to clamp voltage spikes and prevent junction breakdown, especially in automotive solenoid or relay applications.
