Product details
Overview
PDTC114TU,115 from Nexperia is an NPN resistor-equipped transistor (RET) in SOT323 (SC-70) package, featuring integrated 10 kΩ input bias resistor (R1), 50 V VCEO, 100 mA output current capability, and 200 minimum DC current gain (hFE) at IC = 1 mA - used for digital switching and IC input control in space-constrained PCBs.
For engineers reviewing the PDTC114TU,115 datasheet, PDTC114TU,115 pinout, PDTC114TU,115 application, or PDTC114TU,115 equivalent, this part serves as a drop-in replacement for BC847-based digital interface circuits where reduced component count, simplified layout, and consistent biasing are required.
Technical Context
This RET integrates a single NPN silicon transistor with a precision 10 kΩ base-input resistor (R1) and open R2 configuration, eliminating external bias components. It operates with VCEO = 50 V and supports continuous IO up to 100 mA at Tamb ≤ 25 °C.
The device uses standard FR4 PCB mounting with reflow soldering only, exhibits 625 K/W junction-to-ambient thermal resistance, and maintains hFE ≥ 200 at IC = 1 mA and VCE = 5 V - enabling reliable low-power digital switching without external bias network design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - maximum collector-emitter voltage before breakdown; defines safe operating range for 3.3 V/5 V logic-level switching |
| IO | 100 mA - continuous output current rating; sufficient for driving LED indicators or small logic inputs |
| R1 | 10 kΩ (7–13 kΩ range) - built-in base bias resistor; eliminates need for external pull-up/pull-down and reduces BOM count |
| hFE | ≥200 at IC = 1 mA - ensures robust saturation with low base drive; enables direct microcontroller GPIO interfacing |
| VCE(sat) | ≤150 mV at IC = 10 mA / IB = 0.5 mA - guarantees low conduction loss and minimal power dissipation in on-state |
| Ptot | 200 mW - total power dissipation limit at Tamb = 25 °C; sets thermal derating boundary for compact layouts |
Pinout & Package
PDTC114TU,115 is housed in a plastic surface-mounted SOT323 (SC-70) package measuring 2.2 × 1.35 × 1.15 mm, optimized for high-density PCB assembly and automated pick-and-place.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts TTL/CMOS logic-level signals directly without external resistor |
| 2 | GND (emitter) | Common reference node; ties emitter to ground plane for stable switching reference |
| 3 | Output (collector) | Switched output node; drives loads such as LEDs, optocouplers, or logic inputs with controlled current path |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 bias resistor | 10 kΩ ±30% - removes external bias component, reducing footprint and assembly steps |
| Digital switching optimization | Guaranteed hFE ≥200 at IC = 1 mA - ensures full saturation with typical MCU GPIO drive strength |
| Low VCE(sat) | ≤150 mV - minimizes voltage drop and self-heating during sustained on-state operation |
| SOT323 package compatibility | Standard SC-70 footprint - supports existing reflow profiles and AOI inspection workflows |
Applications
| LED Indicator Control | Microcontroller GPIO Interface |
|---|---|
Use Scenario: Driving status LEDs on embedded control panels with limited board area. IC Role / Device Role / Timing Role: NPN switch controlling current path to LED anode while emitter grounded. Use Value: Eliminates discrete base resistor, saving 0.5 mm² PCB area per channel and simplifying layout verification. | Use Scenario: Level-shifting and signal conditioning between 3.3 V microcontrollers and 5 V peripheral inputs. IC Role / Device Role / Timing Role: Digital buffer/inverter with fixed bias; provides clean logic transition without external components. Use Value: Reduces BOM count by one resistor per channel and avoids tolerance-induced timing skew in parallel I/O banks. |
| Optocoupler Input Stage | Logic-Level Signal Switching |
Use Scenario: Providing isolated input drive to PC817-type optocouplers in industrial I/O modules. IC Role / Device Role / Timing Role: Current-limited switch sourcing ~5 mA into optocoupler LED anode. Use Value: Built-in R1 ensures consistent LED forward current across temperature, improving isolation reliability. | Use Scenario: Enabling/disabling power rails or sensor bias lines in battery-powered IoT nodes. IC Role / Device Role / Timing Role: Low-leakage (ICEO ≤ 1 µA) switch isolating downstream circuitry when off. Use Value: Minimizes standby current drain - critical for >10-year battery life in remote sensing applications. |
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 |
|---|---|---|---|
| BC847B,215 | No integrated bias resistors; requires external RB for base drive | Higher design flexibility but increases component count and layout complexity | Select when precise bias tuning or variable gain is needed across operating conditions |
| PDTA114TU,115 | PNP complement with identical R1 = 10 kΩ and SOT323 package | Used for high-side switching or complementary logic stages where emitter is tied to VCC | Select for push-pull configurations or when sourcing current from supply rail is required |
Compared with BC847B,215, PDTC114TU,115 reduces bill-of-materials and layout effort at the cost of fixed bias; versus PDTA114TU,115, it provides NPN topology for low-side switching with ground-referenced load control.

FAQ
What is the function of the internal 10 kΩ resistor in PDTC114TU,115?
The internal 10 kΩ resistor (R1) connects between pin 1 (input/base) and the transistor's base terminal, providing fixed bias current to enable saturation with standard logic-level inputs. It eliminates the need for an external base resistor, reducing component count and PCB area while ensuring repeatable turn-on behavior across temperature and process variation.
Can PDTC114TU,115 be used in linear amplifier applications?
No - PDTC114TU,115 is optimized for digital switching, not analog amplification. Its integrated R1 resistor fixes the base bias point, and its hFE specification is guaranteed only under switching conditions (IC = 1 mA, VCE = 5 V). For linear operation, discrete transistors like BC847B without built-in resistors are recommended to allow adjustable bias networks.
What is the maximum ambient temperature for continuous 100 mA operation?
At 100 mA output current, continuous operation is limited to Tamb ≤ 25 °C due to Ptot = 200 mW and Rth(j-a) = 625 K/W. Derating is required above 25 °C: for example, at 70 °C ambient, max IO drops to approximately 65 mA to maintain Tj ≤ 150 °C, per thermal calculations using ΔT = P × Rth.
Is PDTC114TU,115 compatible with lead-free reflow soldering processes?
Yes - the datasheet specifies reflow soldering as the only recommended method, and the SOT323 package meets JEDEC J-STD-020 moisture sensitivity level (MSL) requirements. The device is rated for peak reflow temperatures up to 260 °C per standard lead-free profiles, with no special pre-bake required for MSL1 handling.
