Product details
Overview
PDTA114TS,126 from Nexperia is a PNP resistor-equipped transistor (RET) in TO-92 through-hole package, featuring integrated 10 kΩ input bias resistor (R1), −50 V collector-emitter voltage rating, −100 mA output current capability, and 500 mW power dissipation at Tamb ≤25 °C - used for digital logic interfacing and low-current peripheral driver circuits.
For engineers reviewing the PDTA114TS,126 datasheet, PDTA114TS,126 pinout, PDTA114TS,126 application, or PDTA114TS,126 equivalent, this page delivers verified electrical parameters, TO-92 terminal mapping, real-world use cases in level-shifting and IC input control, and two validated alternative parts with documented functional and packaging differences.
Technical Context
This device integrates a single PNP bipolar junction transistor with one built-in 10 kΩ base bias resistor (R1); R2 is open. It operates as a digital switch with guaranteed 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 interface with TTL/CMOS logic outputs, it eliminates external base resistors and simplifies PCB layout. Its TO-92 package supports through-hole assembly and provides 250 K/W junction-to-ambient thermal resistance in free air.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - maximum safe collector-emitter voltage under open-base conditions; enables use in 3.3 V to 24 V logic-level switching. |
| IO | −100 mA - continuous output current rating; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 | 10 kΩ (7–13 kΩ range) - integrated base bias resistor; removes need for external pull-up/pull-down components. |
| Ptot | 500 mW - total power dissipation at Tamb ≤25 °C; supports stable operation without heatsinking in ambient-temperature applications. |
| hFE | ≥200 - minimum DC current gain at −1 mA collector current; ensures reliable saturation with standard logic drive levels. |
| VCEsat | ≤ −150 mV - collector-emitter saturation voltage at −10 mA load; minimizes power loss and heat generation in switched mode. |
| Rth(j-a) | 250 K/W - thermal resistance from junction to ambient in free air; defines temperature rise per watt of dissipated power. |
Pinout & Package
Package: TO-92 (SOT54), plastic single-ended leaded through-hole package with 3 leads; body dimensions 5.2 mm × 5.0 mm × 14.5 mm (L×W×H), lead pitch 1.27 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | input (base) | Connected internally to R1; accepts logic-level input signal to enable transistor conduction. |
| 2 | output (collector) | High-side switching node; connects to load supply rail when active; sinks current to emitter. |
| 3 | GND (emitter) | Common reference terminal; tied to system ground or low-side return path; forms current sink path. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 bias resistor | 10 kΩ ±30 % - eliminates discrete resistor placement and reduces BOM count by one component per channel. |
| PNP RET architecture | Single-transistor + resistor topology - enables high-side switching with logic-compatible input without level translation. |
| TO-92 through-hole package | Standard 3-lead leaded format - supports manual prototyping, wave soldering, and legacy board assembly processes. |
| Low VCEsat | ≤ −150 mV at −10 mA - reduces conduction losses and improves efficiency in battery-powered or thermally constrained designs. |
| Wide operating temperature | −65 °C to +150 °C - suitable for industrial and automotive under-hood environments where thermal cycling is critical. |
Applications
| LED Driver Circuit | Microcontroller GPIO Interface |
|---|---|
Use Scenario: Driving 20 mA indicator LEDs from 3.3 V or 5 V microcontroller outputs. IC Role / Device Role / Timing Role: High-side current sink switch controlled by MCU GPIO pin. Use Value: Eliminates need for external base resistor; ensures full saturation with standard logic-high output voltage. |
Use Scenario: Level-shifting and inverting signals between mixed-voltage logic domains (e.g., 1.8 V FPGA to 5 V sensor interface). IC Role / Device Role / Timing Role: Digital inverter and voltage translator with fixed gain and predictable propagation delay. Use Value: Provides clean logic inversion with <100 ns turn-off time and no external passive components required. |
| Relay Coil Driver | Push-Pull Input Protection |
Use Scenario: Switching 12 V relay coils drawing up to 80 mA in industrial control panels. IC Role / Device Role / Timing Role: Low-power PNP switch providing isolated coil energization path. Use Value: Delivers −100 mA output current with ≤−150 mV saturation drop, minimizing relay coil heating and contact arcing. |
Use Scenario: Protecting sensitive analog or digital IC inputs from overvoltage or reverse polarity during hot-plug events. IC Role / Device Role / Timing Role: Clamping and current-limiting element placed in series with input line. Use Value: Leverages built-in R1 to limit fault current while maintaining fast response to transient overvoltage conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTC114TS | NPN complement; same TO-92 package, identical R1 value (10 kΩ), but opposite polarity and current direction. | Used where low-side switching or sink configuration is preferred instead of high-side sourcing. | Select PDTC114TS when circuit requires NPN logic-level switching with matching bias resistor and footprint. |
| BC857B,115 | Discrete PNP BJT without integrated resistor; requires external base resistor; SOT23 surface-mount package. | Suitable for space-constrained PCBs and automated SMT assembly; offers higher hFE (200–450) but adds design complexity. | Choose BC857B,115 when layout allows SMT placement and precise bias tuning is needed for optimized gain or speed. |
Compared with PDTC114TS, PDTA114TS,126 provides high-side switching with integrated biasing, while BC857B,115 demands external components but enables fine-tuned performance in compact layouts - selection depends on polarity requirement, assembly method, and design simplicity priority.

FAQ
What is the package type and mounting style of PDTA114TS,126?
PDTA114TS,126 uses the TO-92 package (JEDEC TO-92, JEITA SC-43A, Nexperia SOT54), a through-hole plastic single-ended leaded package with three leads. It is designed for wave soldering or manual insertion into PCBs and is not a surface-mount device.
Does PDTA114TS,126 have an integrated base resistor, and what is its value?
Yes, PDTA114TS,126 includes a single integrated base bias resistor R1 with a nominal value of 10 kΩ (specified range: 7 kΩ to 13 kΩ). There is no second resistor (R2 is open), making it a single-resistor PNP RET optimized for simple digital switching.
What is the maximum collector-emitter voltage rating for PDTA114TS,126?
The maximum collector-emitter voltage (VCEO) for PDTA114TS,126 is −50 V under open-base conditions. This rating allows safe operation in 24 V industrial control systems and other medium-voltage digital interface applications.
Can PDTA114TS,126 be used as a direct replacement for BC857-series transistors?
PDTA114TS,126 is positioned as a cost-saving alternative to BC857-series transistors in digital applications, but it is not a pin-compatible or functionally identical replacement due to its integrated resistor and TO-92 package. Circuit redesign is required to accommodate the built-in R1 and different pinout.
What is the thermal resistance (Rth(j-a)) of PDTA114TS,126, and how does it affect thermal design?
The junction-to-ambient thermal resistance (Rth(j-a)) of PDTA114TS,126 is 250 K/W in free air. At its 500 mW power dissipation limit, this results in a theoretical 125 °C junction-to-ambient temperature rise - requiring careful ambient temperature management and derating above Tamb = 25 °C to maintain reliability.
