Product details
Overview
PDTC114TEF,115 from Nexperia is an NPN resistor-equipped transistor (RET) with integrated 10 kΩ input bias resistor (R1), open R2 configuration, 50 V VCEO, 100 mA IO, and SOT416 (SC-75) package - used as a digital switch for IC input control and low-power load switching in space-constrained consumer and industrial PCBs.
For engineers reviewing the PDTC114TEF,115 datasheet, PDTC114TEF,115 pinout, PDTC114TEF,115 application, or PDTC114TEF,115 equivalent, this part serves as a drop-in replacement for BC847-based digital interface circuits where simplified biasing, reduced component count, and 3-pin surface-mount compatibility are required.
Technical Context
The PDTC114TEF,115 integrates a single NPN silicon transistor with a monolithically fabricated 10 kΩ base-input resistor (R1) and no internal emitter-base feedback resistor (R2 = open), enabling direct logic-level drive without external bias components. Its architecture eliminates discrete base resistors while maintaining standard BJT switching behavior under IC/IB = 20 saturation conditions.
It operates within −65 °C to +150 °C junction temperature range, supports reflow soldering only, and delivers VCE(sat) ≤ 150 mV at IC = 10 mA / IB = 0.5 mA - optimized for low-loss digital on/off control in 3.3 V and 5 V logic systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V maximum - supports reliable switching of 24 V DC loads with safety margin in industrial I/O modules. |
| IO | 100 mA continuous output - sufficient to drive LED indicators, small relays, or logic inputs without external current amplification. |
| R1 | 10 kΩ ±30 % (7–13 kΩ) - sets standard TTL/CMOS-compatible base current for predictable turn-on with 3.3 V or 5 V microcontroller GPIO. |
| VCE(sat) | ≤150 mV at IC = 10 mA, IB = 0.5 mA - minimizes power loss and self-heating in high-duty-cycle digital switching applications. |
| Ptot | 150 mW at Tamb ≤25 °C (SOT416) - defines thermal derating envelope for compact PCB layouts with limited copper area. |
| hFE | ≥200 at VCE = 5 V, IC = 1 mA - ensures robust current gain for stable switching across process and temperature variations. |
| Rth(j-a) | 833 K/W - indicates thermal limitation in free-air operation; requires careful layout or derating above 25 °C ambient. |
Pinout & Package
SOT416 (SC-75) ultra-small plastic surface-mounted package: 1.8 mm × 1.4 mm × 0.95 mm body, 3-lead, single-sided FR4 mounting, reflow-only assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | input (base) | Connected internally to R1; accepts logic-level voltage directly from MCU GPIO or gate driver output. |
| 2 | output (collector) | Switched high-side node; connects to load anode or pull-up rail in low-side switching topology. |
| 3 | GND (emitter) | Common reference and return path; must be tied to system ground plane for stable bias and thermal conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 bias resistor | Eliminates need for external base resistor - reduces BOM count by one passive and saves 1.5 mm² PCB area per instance. |
| Open R2 configuration | Enables full logic-level control without emitter feedback; simplifies design for non-inverting digital switches and level translators. |
| 100 mA output capability | Supports direct driving of optocouplers, small solenoids, or multiple parallel logic inputs without buffer stages. |
| SOT416 footprint | Compatible with standard 0603 pick-and-place equipment and reflow profiles - enables automated assembly in high-volume production. |
| BC847 series alternative | Reduces design time and test validation effort when upgrading legacy discrete BJT designs to integrated RET solutions. |

FAQ
What is the exact package type and dimensions of PDTC114TEF,115?
The PDTC114TEF,115 uses the SOT416 (SC-75) package: 1.8 mm × 1.4 mm × 0.95 mm body size with 3 leads, optimized for high-density surface-mount assembly. Its standardized footprint matches JEDEC SC-75 mechanical specifications and supports reflow-only soldering per manufacturer guidelines.
Does PDTC114TEF,115 include both R1 and R2 bias resistors?
No - PDTC114TEF,115 features only R1 = 10 kΩ (±30 %) connected between pin 1 (base) and internal transistor base; R2 is explicitly open (not populated), making it suitable for non-inverting digital switch configurations where emitter feedback is not required.
What is the maximum continuous collector current rating for PDTC114TEF,115?
The PDTC114TEF,115 is rated for 100 mA continuous output current (IO) under normal operating conditions. This value is confirmed in Table 2 (Quick reference data) and aligns with its 150 mW total power dissipation limit in the SOT416 package at Tamb ≤25 °C.
Can PDTC114TEF,115 replace BC847B in existing designs?
Yes - PDTC114TEF,115 is positioned as a cost-saving, space-efficient alternative to BC847-series transistors in digital applications. It integrates the base resistor, eliminating one external component while matching key parameters including VCEO = 50 V, IC = 100 mA, and hFE ≥200, though pinout differs (SOT416 vs. SOT23).
What is the thermal resistance (Rth(j-a)) of PDTC114TEF,115 in free air?
The PDTC114TEF,115 has a junction-to-ambient thermal resistance of 833 K/W when mounted on an FR4 PCB with single-sided copper and standard footprint, as specified in Table 7. This value governs safe operating area derating above 25 °C ambient temperature.
