Product details
Overview
PDTC114TM from Nexperia is an NPN resistor-equipped transistor (RET) with integrated 10 kΩ input bias resistor (R1), designed for digital switching applications where simplified base drive and reduced component count are critical. It delivers 100 mA output current, supports 50 V collector-emitter voltage, and uses the ultra-compact SOT883 (SC-101) package measuring 1.0 × 0.6 × 0.5 mm - commonly deployed in space-constrained portable logic interfaces and LED driver stages.
For engineers reviewing the PDTC114TM datasheet, PDTC114TM pinout, PDTC114TM application, or PDTC114TM equivalent, key selection considerations include its built-in R1 value (7–13 kΩ), emitter-grounded configuration, 150 °C junction temperature rating, and suitability as a cost-saving BC847-series alternative in low-power digital control circuits.
Technical Context
This RET integrates a single NPN silicon transistor with a precision laser-trimmed 10 kΩ base-input resistor (R1); R2 is open, confirming a single-resistor topology optimized for direct microcontroller GPIO interfacing. Its internal structure eliminates external base resistors while maintaining predictable DC current gain (hFE ≥ 200 at IC = 1 mA, VCE = 5 V).
The device operates with fixed terminal assignment: Pin 1 is base input, Pin 2 is emitter (GND), and Pin 3 is collector output - consistent across SOT883, SOT23, SOT323, and SOT346 variants. Thermal resistance (Rth(j-a)) is 500 K/W under standard FR4 PCB mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - maximum safe collector-emitter voltage with base open; defines rail compatibility up to 5 V logic systems with margin. |
| IO | 100 mA - continuous DC output current capability; sufficient for driving LEDs, small relays, or logic-level MOSFET gates. |
| R1 | 7–13 kΩ (typ. 10 kΩ) - integrated base bias resistor enabling direct connection to 3.3 V/5 V MCU outputs without external components. |
| hFE | ≥200 - minimum DC current gain at IC = 1 mA, VCE = 5 V; ensures reliable saturation with low base drive current. |
| VCEsat | ≤150 mV at IC = 10 mA, IB = 0.5 mA - low saturation voltage minimizes power loss and heat generation in switching mode. |
| Ptot | 250 mW - total power dissipation limit at Tamb ≤ 25 °C; constrains usable current in high-ambient environments. |
| Tj max | 150 °C - maximum junction temperature; supports operation in industrial ambient conditions up to +85 °C with proper layout. |
Pinout & Package
SOT883 (SC-101) is a leadless ultra-small plastic package with three solder lands, body dimensions of 1.0 × 0.6 × 0.5 mm, and bottom-side thermal pad exposure for enhanced heat transfer on PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Accepts TTL/CMOS logic-level drive; internally connected to R1; no external pull-up/down required. |
| 2 | GND (emitter) | Emitter tied directly to system ground; serves as common reference for input and output paths. |
| 3 | Output (collector) | Switches load between VCC and this node; configured for low-side switching in most implementations. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in bias resistor R1 | 10 kΩ ±30% - eliminates need for discrete base resistor, reducing BOM count and PCB area by one passive component. |
| Ultra-small SOT883 footprint | 1.0 × 0.6 mm - enables placement in dense mobile and wearable PCB layouts where space is constrained below 1 mm². |
| 100 mA output current | Supports direct driving of indicator LEDs, optocoupler inputs, and small-signal loads without external amplification. |
| Low VCEsat (≤150 mV) | Reduces conduction losses during ON-state, improving efficiency in battery-powered digital interface stages. |
| 150 °C junction rating | Enables reliable operation in thermally demanding environments such as enclosed industrial controllers or automotive cabin modules. |
Applications
| LED Indicator Control | Microcontroller GPIO Interface |
|---|---|
|
Use Scenario: Driving status LEDs on compact IoT sensor nodes powered by coin-cell or Li-ion batteries. IC Role / Device Role / Timing Role: Low-side switch controlled by MCU GPIO pin to turn on/off red/green/blue indicator LEDs. Use Value: Integrated R1 allows direct GPIO connection without external resistor; 100 mA rating supports multiple parallel LEDs; low VCEsat extends battery life. |
Use Scenario: Level-shifting and signal conditioning between 1.8 V FPGA I/O banks and 3.3 V peripheral logic. IC Role / Device Role / Timing Role: Digital buffer and voltage translator, isolating sensitive FPGA pins from higher-current loads. Use Value: Predictable hFE ≥200 ensures stable switching at low drive currents; SOT883 size matches fine-pitch FPGA routing constraints. |
| Optocoupler Input Stage | Small-Relay Driver |
|
Use Scenario: Providing isolated feedback signals from motor drivers in industrial PLC I/O modules. IC Role / Device Role / Timing Role: Current-limited switch sourcing ~10 mA into optocoupler LED anode (with emitter grounded). Use Value: R1 tolerance (±30%) and hFE consistency ensure repeatable LED forward current; 50 V VCEO accommodates 24 V supply rails. |
Use Scenario: Activating 5 V/12 V signal relays in smart home hub power management subsystems. IC Role / Device Role / Timing Role: Low-side driver switching relay coil between GND and VCC, controlled by MCU PWM or digital output. Use Value: 100 mA IO rating covers typical 5 V relay coils (40–70 mA); 250 mW Ptot allows brief overcurrent during coil energization. |
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) package; larger footprint (3.0 × 1.7 mm); same R1 = 10 kΩ, VCEO = 50 V, IO = 100 mA. | Better thermal performance (Rth(j-a) = 500 K/W, same as PDTC114TM) but requires more PCB area; compatible with standard pick-and-place feeders. | Select when board space permits and legacy SMT equipment favors SC-59A tape formats. |
| BC847B,115 | Standard NPN BJT (no built-in resistor); requires external 10 kΩ base resistor; identical SOT23 package and hFE spec. | Higher BOM count and layout complexity; offers greater flexibility in biasing (e.g., adjustable R1/R2 networks) but no integration benefit. | Select when design requires variable base current or dual-resistor biasing for analog-linear operation. |
Compared with PDTC114TK and BC847B,115, the PDTC114TM uniquely combines ultra-miniature SOT883 packaging with monolithic R1 integration - delivering the smallest possible footprint per function while eliminating one passive component and associated layout risk.

FAQ
What is the marking code for PDTC114TM?
The top-side marking code for PDTC114TM is "DT", as specified in Table 5 of the official Nexperia datasheet (Rev. 08, 2006). This two-character code is laser-etched on the package surface and used for traceability and visual identification during assembly and inspection.
Can PDTC114TM be used in linear amplifier configurations?
No - PDTC114TM is optimized for digital switching, not linear amplification. Its internal R1 is fixed and unadjustable, and datasheet characteristics (e.g., hFE test conditions, VCEsat focus) reflect saturated-switch operation. For analog gain stages, use standard BJTs like BC847B with externally tuned bias networks.
Is reflow soldering mandatory for PDTC114TM?
Yes - according to Section 5 of the datasheet, reflow soldering is the only recommended method for PDTC114TM (SOT883). Wave or hand soldering may damage the ultra-thin package or compromise solder joint integrity due to thermal stress on the 0.12 mm leadframe thickness and small pad geometry.
What is the thermal resistance (Rth(j-a)) of PDTC114TM on FR4 PCB?
The thermal resistance from junction to ambient for PDTC114TM mounted on standard FR4 PCB (single-sided copper, tin-plated, standard footprint) is 500 K/W, as confirmed in Table 7 of the datasheet. This value assumes no additional copper pour or thermal vias; adding 20 mm² of 2 oz copper on the backside can reduce it by ~30%.
