Product details
Overview
PDTC114TT from Nexperia is an NPN resistor-equipped transistor (RET) with integrated 10 kΩ base bias resistor (R1), designed for digital switching applications where simplified drive circuitry and reduced component count are critical. It delivers 100 mA output current, supports 50 V collector-emitter voltage, and uses the SOT23 (TO-236AB) surface-mount package for space-constrained PCB layouts in logic-level interface circuits.
For engineers reviewing the PDTC114TT datasheet, PDTC114TT pinout, PDTC114TT application, or PDTC114TT equivalent, this device serves as a cost-optimized, drop-in alternative to discrete BJT + resistor combinations in microcontroller I/O buffering, LED load control, and level-shifting interfaces requiring predictable turn-on behavior without external bias network design.
Technical Context
This RET integrates a single 10 kΩ input bias resistor (R1) between base and input terminal, with R2 open - enabling direct connection to CMOS/TTL logic outputs. Its internal resistor network eliminates need for external base resistors while maintaining 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).
The device operates across −65 °C to +150 °C ambient temperature range, with thermal resistance Rth(j-a) of 500 K/W on FR4 PCB, and meets IEC 60134 absolute maximum ratings including 50 V VCBO and VEBO = 5 V - ensuring robustness in industrial digital signal conditioning and low-power switching nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage under open-base condition; defines upper rail limit for switching loads. |
| IO | 100 mA - Continuous DC output current capability; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 | 10 kΩ (7–13 kΩ range) - Integrated base bias resistor enabling direct logic-level drive without external components. |
| hFE | ≥200 at IC = 1 mA - Ensures reliable saturation with low base drive current (e.g., 5 µA from 5 V MCU GPIO). |
| VCEsat | ≤150 mV at IC = 10 mA, IB = 0.5 mA - Minimizes power loss and heat generation during on-state operation. |
| Ptot | 250 mW at Tamb ≤25 °C - Thermal limit defining maximum dissipation in standard SOT23 footprint on FR4 board. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package, 3-lead, body size 2.9 × 1.3 × 1.0 mm; optimized for automated placement and reflow soldering per JEDEC J-STD-020.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | input (base) | Connected internally to R1; accepts logic-level voltage (e.g., 3.3 V/5 V) to enable transistor conduction. |
| 2 | GND (emitter) | Common reference node; ties emitter directly to ground plane, simplifying return path layout. |
| 3 | output (collector) | Switched high-side output node; connects to load (e.g., LED anode or relay coil) referenced to positive rail. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in 10 kΩ base bias resistor | Eliminates external resistor placement and routing, reducing BOM count and PCB area by ~2 components per switch node. |
| 100 mA continuous output current | Supports direct driving of medium-current loads like indicator LEDs, optocoupler inputs, or small-signal MOSFET gates. |
| Low VCEsat (≤150 mV) | Reduces conduction loss and self-heating, enabling stable operation in thermally constrained environments. |
| SOT23 package compatibility | Enables use with standard pick-and-place equipment and reflow profiles; footprint matches industry-standard TO-236AB land pattern. |
Applications
| Microcontroller I/O Buffering | LED Indicator Control |
|---|---|
Use Scenario: Driving 5 V logic signals from low-current MCU GPIO pins into higher-current loads. IC Role / Device Role / Timing Role: Digital switch translating weak logic output into robust current sink capability. Use Value: Eliminates need for external base resistor and reduces layout complexity while ensuring guaranteed saturation at 3.3 V/5 V logic levels. |
Use Scenario: Controlling status LEDs on embedded system front panels with precise current limiting. IC Role / Device Role / Timing Role: Constant-current switch regulating LED brightness via fixed VCEsat and known R1-driven IB. Use Value: Delivers consistent 10–20 mA LED current without external current-setting resistor, improving manufacturing yield and board density. |
| Level-Shifting Interface | Optocoupler Input Driver |
Use Scenario: Translating 3.3 V logic signals to 5 V or 12 V domains in mixed-voltage systems. IC Role / Device Role / Timing Role: Active pull-down switch enabling bidirectional voltage translation with minimal propagation delay. Use Value: Provides clean, fast turn-off due to low Cc (2.5 pF) and avoids shoot-through risk in open-collector configurations. |
Use Scenario: Supplying controlled forward current to optocoupler LED inputs in isolated feedback paths. IC Role / Device Role / Timing Role: Current-regulated driver ensuring stable CTR performance across temperature and supply variations. Use Value: Maintains >1 mA input current into optocoupler even at 3.3 V logic, meeting minimum IF requirements without additional biasing. |
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 |
|---|---|---|---|
| PDTC114TK | SOT346 (SC-59A/TO-236) package; identical R1 = 10 kΩ, same VCEO = 50 V and IO = 100 mA. | Larger footprint and higher thermal resistance (Rth(j-a) = 500 K/W vs. SOT23's 500 K/W - same value but different mounting geometry). | Select when legacy TO-236 layout compatibility or higher mechanical robustness is required over miniaturization. |
| BC847B,115 | Standard NPN BJT (no built-in resistors); requires external 10 kΩ base resistor; hFE = 200–450 (wider tolerance). | Higher component count and layout area; less predictable turn-on threshold without integrated R1. | Choose only if design requires adjustable base bias or multi-stage amplification beyond simple switching. |
Compared with PDTC114TK and BC847B,115, the PDTC114TT offers identical electrical performance in a smaller SOT23 footprint with guaranteed resistor matching, reducing design iteration time and assembly cost in high-volume digital interface applications.

FAQ
What is the function of R2 in PDTC114TT?
R2 is open (not connected) in PDTC114TT - only R1 (10 kΩ) is integrated between pin 1 (input/base) and the internal transistor base. This configuration provides single-resistor biasing ideal for simple logic-driven switching, unlike dual-resistor RETs used for voltage-divider biasing or ESD protection.
Can PDTC114TT be used in linear amplifier mode?
No - PDTC114TT is characterized and qualified exclusively for switching operation. Its hFE specification applies only at IC = 1 mA and VCE = 5 V under saturated conditions, and no small-signal parameters (e.g., fT, gm) are provided in the datasheet for analog gain applications.
Is PDTC114TT RoHS compliant and halogen-free?
Yes - PDTC114TT meets RoHS Directive 2011/65/EU and is halogen-free per Nexperia's material declarations. The device carries the "Nexperia Green" marking and conforms to JEDEC J-STD-020 moisture sensitivity level (MSL) 1 for unlimited floor life under standard conditions.
What is the maximum operating junction temperature?
The maximum junction temperature (Tj) is 150 °C, as specified in Table 6 of the datasheet. This limit must not be exceeded during operation - derating is required above Tamb = 25 °C using Rth(j-a) = 500 K/W to ensure thermal reliability in sustained 100 mA switching duty cycles.
