Product details
Overview
PDTC114TS,126 from Nexperia is an NPN resistor-equipped transistor (RET) in TO-92 (SOT54) through-hole package, featuring integrated 10 kΩ base bias resistor (R1), 50 V VCEO, 100 mA output current capability, and open R2 configuration - used as a digital switch for IC input control and load switching in industrial control and consumer electronics.
For engineers reviewing the PDTC114TS,126 datasheet, PDTC114TS,126 pinout, PDTC114TS,126 application, or PDTC114TS,126 equivalent, this page delivers verified electrical parameters, TO-92 terminal mapping, real-world use cases, and two validated alternative parts for cost-sensitive digital switching designs.
Technical Context
The PDTC114TS,126 integrates a single NPN bipolar junction transistor with a monolithically embedded 10 kΩ input bias resistor (R1) and no second resistor (R2 = open), eliminating external base resistors in saturated-switch applications. It operates with fixed DC current gain (hFE ≥ 200 at IC = 1 mA, VCE = 5 V) and low saturation voltage (VCEsat ≤ 150 mV at IC = 10 mA, IB = 0.5 mA).
Designed for direct interfacing with 3.3 V/5 V logic outputs, it supports ambient temperatures from −65 °C to +150 °C and junction temperatures up to 150 °C. Its TO-92 package delivers 500 mW total power dissipation and 250 K/W thermal resistance from junction to ambient in free air.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - maximum collector-emitter voltage before breakdown; enables use in 24 V industrial logic interfaces. |
| IO | 100 mA - continuous output current rating; sufficient for driving LEDs, relays, and small solenoids. |
| R1 | 10 kΩ (7–13 kΩ range) - built-in base bias resistor; eliminates need for external pull-up/pull-down components. |
| hFE | ≥200 at IC = 1 mA - high DC current gain ensures reliable saturation with minimal drive current. |
| VCEsat | ≤150 mV at IC = 10 mA - low saturation voltage minimizes power loss and heat generation in switching mode. |
| Ptot | 500 mW - total power dissipation in TO-92 package; supports moderate-duty cycling without heatsinking. |
| Rth(j-a) | 250 K/W - thermal resistance enables stable operation at full load up to +75 °C ambient. |
Pinout & Package
PDTC114TS,126 uses the TO-92 (SOT54) through-hole plastic package with standard lead spacing and 5.2 mm × 4.8 mm × 14.5 mm body dimensions. Pin 1 is base (input), Pin 2 is collector (output), and Pin 3 is emitter (GND), matching JEDEC TO-92 mechanical outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | input (base) | Accepts logic-level drive signal; internally connected to R1 (10 kΩ) - no external bias required. |
| 2 | output (collector) | Switched high-side output node; connects to load (e.g., LED anode or relay coil) referenced to VCC. |
| 3 | GND (emitter) | Common reference terminal; ties directly to system ground and completes switching path for load current. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 bias resistor | 10 kΩ ±30% reduces BOM count by one passive component per switch channel. |
| NPN RET architecture | Eliminates need for discrete base resistor placement and pick-and-place steps during assembly. |
| 100 mA output capability | Supports direct drive of medium-current loads like indicator LEDs and small-signal relays. |
| TO-92 through-hole package | Enables prototyping, manual soldering, and legacy board compatibility without SMT rework. |
| Low VCEsat | ≤150 mV ensures <1.5 mW conduction loss at 10 mA - critical for thermally constrained enclosures. |
Applications
| Industrial Control Input Interface | Consumer Appliance Power Sequencing |
|---|---|
|
Use Scenario: Isolating and conditioning 24 V PLC output signals before feeding into microcontroller GPIO pins. IC Role / Device Role / Timing Role: Digital switch translating industrial logic levels to 3.3 V/5 V compatible inputs while providing current limiting and noise immunity. Use Value: Eliminates external resistor networks and reduces PCB footprint by 30% versus discrete BJT + resistor solution. |
Use Scenario: Enabling sequential power-up of subsystems (e.g., display backlight, motor driver, sensor bus) in washing machine mainboard. IC Role / Device Role / Timing Role: Low-side load switch controlled by MCU GPIO to gate power to downstream modules. Use Value: Delivers 100 mA per channel with <150 mV drop - minimizing voltage sag and thermal rise during startup surges. |
| LED Status Indicator Driver | Microcontroller Reset Signal Conditioning |
|
Use Scenario: Driving multi-color status LEDs on network equipment front panels using 3.3 V logic outputs. IC Role / Device Role / Timing Role: Constant-current switch with fixed gain and saturation behavior for predictable LED brightness control. Use Value: Built-in R1 ensures consistent turn-on threshold across temperature (−65 °C to +150 °C), avoiding brightness drift. |
Use Scenario: Debouncing and level-shifting push-button reset inputs to match MCU reset pin voltage thresholds and timing requirements. IC Role / Device Role / Timing Role: Edge-triggered switch converting mechanical contact bounce into clean, logic-compatible reset pulses. Use Value: Fast turn-on/off response (<100 ns propagation delay implied by hFE/Cc specs) prevents false resets during transient noise events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN digital switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847B,215 | No integrated bias resistor; requires external 10 kΩ base resistor for same function. | Higher hFE (200–450) but adds component count and layout area. | Select when design already uses discrete BJTs and needs tighter hFE tolerance. |
| PDTA114TS,126 | PNP complement with identical R1 value, TO-92 package, and matching pinout (Pin 1 = base, Pin 2 = emitter, Pin 3 = collector). | Used for high-side switching or inverted logic paths where sourcing current is required. | Select when complementary PNP action is needed in same footprint without redesigning layout. |
Compared with BC847B,215, PDTC114TS,126 reduces bill-of-materials and assembly cost by integrating R1; compared with PDTA114TS,126, it provides NPN polarity for low-side switching - enabling direct replacement only in non-inverting configurations.

FAQ
What is the package type and mounting style of PDTC114TS,126?
PDTC114TS,126 uses the TO-92 (SOT54) through-hole plastic package with three leads arranged in standard JEDEC pinout (Pin 1 = base, Pin 2 = collector, Pin 3 = emitter). It is designed for wave or hand soldering onto through-hole PCBs and supports bulk packing in straight-lead format per ordering code -412.
Does PDTC114TS,126 include both R1 and R2 bias resistors?
No, PDTC114TS,126 includes only R1 = 10 kΩ (7–13 kΩ range) between base and input; R2 is open (not connected). This configuration simplifies single-resistor biasing for standard digital switching, distinguishing it from dual-resistor RET variants like PDTC144ET.
What is the maximum continuous collector current for PDTC114TS,126?
The maximum continuous output current (IO) for PDTC114TS,126 is 100 mA, as specified in the Quick Reference Data table. This rating applies under standard FR4 PCB conditions at Tamb ≤ 25 °C and aligns with its 500 mW power dissipation limit in the TO-92 package.
Can PDTC114TS,126 replace BC847 series transistors directly?
PDTC114TS,126 serves as a cost-saving alternative to BC847 series in digital switching applications, but it is not a pin-to-pin drop-in replacement due to integrated R1. External resistor removal is required when substituting - the device simplifies circuit design rather than enabling blind replacement.
What is the thermal resistance (Rth(j-a)) of PDTC114TS,126?
The thermal resistance from junction to ambient (Rth(j-a)) for PDTC114TS,126 is 250 K/W when mounted on an FR4 PCB with single-sided copper and standard footprint, as stated in Table 7. This value enables thermal design margin estimation for continuous 100 mA operation at elevated ambient temperatures.
