Product details

Overview

PDTC114ES,126 from NXP Semiconductors (formerly Philips) is an NPN resistor-equipped transistor with integrated 47 kΩ base bias resistors (R1 and R2), rated for 50 V V_CEO, 100 mA DC output current, and housed in a through-hole SOT54 (TO-92) package. It serves as a single-device replacement for discrete BJT + two-resistor bias networks in low-power switching applications such as logic-level interface drivers and signal inversion circuits.

For engineers reviewing the PDTC114ES,126 datasheet, PDTC114ES,126 pinout, PDTC114ES,126 application, or PDTC114ES,126 equivalent, key selection criteria include its fixed 47 kΩ input resistor ratio, guaranteed 80 minimum h_FE at 5 V/5 mA, 150 mV V_CE(sat) at 10 mA/0.5 mA drive, and compatibility with standard through-hole PCB assembly processes.

Technical Context

This device integrates two precision 47 kΩ resistors (R1 between base and input, R2 between base and emitter) to form a monolithic digital transistor structure. Its internal configuration enables direct connection to CMOS/TTL logic outputs without external bias components, simplifying level translation and reducing board space.

Designed for DC switching rather than linear amplification, it features a guaranteed minimum DC current gain (h_FE) of 80 at V_CE = 5 V and I_C = 5 mA, and operates reliably across −65 °C to +150 °C ambient temperature with a maximum junction temperature of 150 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	50 V - Maximum collector-emitter voltage before breakdown; supports 24 V and 3.3/5 V logic interfacing with margin.
I_O (DC)	100 mA - Continuous output current capability; suitable for driving LEDs, small relays, and logic inputs.
R1 / R2	47 kΩ each - Fixed internal bias network eliminates need for external resistors; ensures consistent turn-on behavior.
h_FE	≥80 at 5 V/5 mA - Minimum DC current gain guarantees reliable saturation under typical microcontroller GPIO drive conditions.
V_CE(sat)	≤150 mV at I_C=10 mA/I_B=0.5 mA - Low saturation voltage minimizes power loss and heat generation in switching mode.
P_tot	500 mW at T_amb ≤25 °C - Total power dissipation rating in SOT54 package; enables operation without heatsinking in low-duty-cycle apps.

Pinout & Package

PDTC114ES,126 uses the SOT54 (TO-92) through-hole plastic package with 3 leads and a body dimension of 4.8 × 4.2 × 14.5 mm. The package supports standard wave soldering and is compatible with legacy through-hole manufacturing lines.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Internal connection to both R1 (input) and R2 (emitter feedback); no external base connection required.
2	Collector	Main current output terminal; connects to load supply rail (e.g., 5 V, 12 V, or 24 V).
3	Emitter	Current return path to ground; internally tied to R2; provides common reference for input signal.

Key Features

Feature	Design Value
Integrated bias network	Monolithic 47 kΩ R1–R2 resistor pair eliminates two external components and associated layout area.
Guaranteed h_FE ≥80	Ensures predictable saturation with standard 3.3 V/5 V MCU GPIO outputs without additional current boosting.
V_CE(sat) ≤150 mV	Reduces conduction losses below 1.5 mW at 10 mA load, improving efficiency in battery-powered interfaces.
Through-hole SOT54 package	Enables use in prototyping, repair, and industrial control systems requiring mechanical robustness and serviceability.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN digital transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
PDTC114ET,115	SOT23 surface-mount package; same R1/R2 values and electrical specs but lower P_tot (250 mW) and higher thermal resistance (500 K/W).	Requires reflow-only assembly; unsuitable for through-hole prototyping or high-temperature environments above 85 °C ambient.	Select when board space is constrained and automated SMT assembly is available.

FAQ

What is the pin configuration of PDTC114ES,126?

PDTC114ES,126 uses a standard SOT54 (TO-92) package with pin 1 as Base, pin 2 as Collector, and pin 3 as Emitter. This configuration matches JEDEC TO-92 outline and is verified in the official Philips/NXP datasheet revision 2004 Aug 17. The internal R1–R2 network connects directly to these terminals, eliminating external base wiring.

Does PDTC114ES,126 require external bias resistors?

No, PDTC114ES,126 does not require external bias resistors. It integrates two 47 kΩ resistors: R1 between the input (base) and pin 1, and R2 between pin 1 and emitter (pin 3). This built-in network allows direct connection to logic outputs, confirmed in the "Quick Reference Data" and "Simplified Outline" sections of the PDTC114ES,126 datasheet.

What is the maximum continuous collector current for PDTC114ES,126?

The maximum continuous DC collector current (I_O) for PDTC114ES,126 is 100 mA, as specified in the "Quick Reference Data" table and confirmed under "Limiting Values" in the datasheet. This rating applies at T_amb ≤25 °C with the SOT54 package, and derates linearly above that ambient temperature per the thermal characteristics.

Can PDTC114ES,126 be used in linear amplification applications?

PDTC114ES,126 is optimized for switching-not linear amplification. Its datasheet specifies h_FE only at V_CE = 5 V and I_C = 5 mA, and does not characterize gain linearity, frequency response, or noise performance. For analog amplification, a standard BJT like BC847B or PN2222A is recommended instead of PDTC114ES,126.

What is the V_CE(sat) specification for PDTC114ES,126?

The collector-emitter saturation voltage (V_CE(sat)) for PDTC114ES,126 is guaranteed ≤150 mV at I_C = 10 mA and I_B = 0.5 mA, per the "Characteristics" table in the datasheet. This low saturation voltage ensures minimal power loss during switching, making PDTC114ES,126 suitable for efficient digital interface and load-driving tasks.
