Product details
Overview
PDTC115TM,315 from Nexperia is an NPN resistor-equipped transistor (RET) with integrated 100 kΩ base bias resistor (R1), designed for compact switching and amplification in space-constrained PCB layouts. It delivers 100 mA DC output current, supports 50 V collector-emitter voltage, and uses the ultra-small SOT883 (SC-101) package measuring 1.0 × 0.6 × 0.5 mm - commonly deployed in LED driver stages and logic-level interface circuits.
For engineers reviewing the PDTC115TM,315 datasheet, PDTC115TM,315 pinout, PDTC115TM,315 application, or PDTC115TM,315 equivalent, key selection criteria include built-in bias resistor value (70–130 kΩ), low VCEsat (≤150 mV at IC = 5 mA/IB = 0.25 mA), thermal resistance (500 K/W), junction temperature rating (150 °C), and SOT883 land-pattern compatibility.
Technical Context
This device integrates a single NPN silicon transistor with a monolithically embedded 100 kΩ input bias resistor (R1) and open R2 configuration - eliminating external base resistors and reducing component count. Its internal resistor network enables direct connection to CMOS/TTL logic outputs without level-shifting circuitry.
The SOT883 package features a 3-terminal leadless structure with terminals arranged as Base–Emitter–Collector (Pin 1–2–3), optimized for high-density reflow assembly on FR4 PCBs. Thermal performance is specified under JEDEC-standard reflow conditions with 60 µm copper trace width.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - maximum safe collector-emitter voltage with base open; defines off-state blocking capability in switching applications. |
| IO (DC) | 100 mA - continuous collector current handling capacity; suitable for driving small relays, LEDs, or logic buffers. |
| R1 | 70–130 kΩ (typ. 100 kΩ) - integrated base bias resistor; sets input current sensitivity and eliminates need for discrete pull-up/pull-down components. |
| VCEsat | ≤150 mV at IC = 5 mA / IB = 0.25 mA - low saturation voltage ensures minimal power loss and heat generation during on-state operation. |
| Ptot | 250 mW at Tamb ≤ 25 °C - total power dissipation limit; constrains usable current/voltage combinations in ambient-limited environments. |
| hFE | ≥100 at VCE = 5 V, IC = 1 mA - DC current gain sufficient for reliable digital switching with margin against process variation. |
| Cc | 2.5 pF at VCB = 10 V, f = 1 MHz - low collector capacitance supports fast switching transitions and reduces signal distortion in high-frequency interfaces. |
Pinout & Package
SOT883 (SC-101) is a leadless ultra-small plastic package with three solder lands, body dimensions 1.0 × 0.6 × 0.5 mm, designed for automated surface-mount reflow assembly only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level drive signals directly without external biasing components. |
| 2 | GND (emitter) | Common reference node; must be tied to system ground or low-side return path for proper transistor biasing. |
| 3 | Output (collector) | Switched high-side output node; connects to load (e.g., LED anode, relay coil) with supply referenced to VCC. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in bias resistor (R1) | 100 kΩ ±30% - eliminates two external resistors per switch stage, reducing BOM count and layout area by ~30% in multi-channel designs. |
| Ultra-compact SOT883 footprint | 1.0 × 0.6 mm - enables placement in tight spaces such as wearable sensor modules and miniaturized IoT edge nodes. |
| Low VCEsat | ≤150 mV - minimizes conduction loss and self-heating, supporting stable operation at 100 mA without heatsinking. |
| High hFE | ≥100 - ensures robust turn-on margin across temperature (-65 °C to +150 °C) and manufacturing spread. |
| Reflow-only assembly | JEDEC-compliant SOT883 profile - guarantees mechanical reliability and solder joint integrity in high-volume manufacturing. |
Applications
| LED Driver Stage | Logic-Level Interface |

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 |
|---|---|---|---|
| PDTA115TM | PNP complement with same R1 value and SOT883 package; VCEO = −50 V, IO = −100 mA. | Used where active-low switching or high-side sourcing is required instead of low-side sinking. | Select when polarity reversal is needed - e.g., driving PMOS gate or sourcing current to VCC rail. |
| PDTC124EM,315 | Different R1 = 22 kΩ (vs. 100 kΩ); otherwise identical SOT883 package, VCEO = 50 V, IO = 100 mA. | Higher base current enables faster switching in high-speed digital buffers but increases input power draw. | Choose for improved switching speed (>10% reduction in tON/tOFF) at cost of ~4.5× higher input current consumption. |
Compared with PDTA115TM and PDTC124EM,315, PDTC115TM,315 offers optimal balance of input sensitivity (100 kΩ R1), low-power drive capability, and compact size - making it preferred for battery-sensitive, space-constrained low-to-moderate speed switching.

FAQ
What is the function of the internal resistor R1 in PDTC115TM,315?
R1 is a monolithically integrated 100 kΩ base bias resistor that provides current-limiting and biasing for the NPN transistor. It enables direct connection to CMOS/TTL logic outputs without external components, reducing board area and assembly steps. The resistor is connected between Pin 1 (base) and the internal transistor base node, with R2 left open as specified in the datasheet.
Can PDTC115TM,315 be used in high-frequency switching applications?
Yes - its 2.5 pF collector capacitance and ≤150 mV VCEsat support switching up to several hundred kHz in digital interface and LED dimming applications. However, it is not characterized for RF or MHz-range operation; for >1 MHz use, discrete transistors with lower Cc and faster hFE response are recommended.
Is PDTC115TM,315 RoHS compliant and halogen-free?
Yes - PDTC115TM,315 meets RoHS Directive 2011/65/EU and is halogen-free per Nexperia's product compliance documentation. The SOT883 package uses lead-free matte tin terminal finish and complies with JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) for unlimited floor life at ≤30 °C/85% RH.
How does thermal performance of PDTC115TM,315 compare across package variants?
PDTC115TM,315 in SOT883 has Rth(j-a) = 500 K/W - identical to SOT346 and SOT23 variants but higher than through-hole SOT54 (250 K/W). This means it dissipates less heat into ambient air; design margins require derating above 25 °C ambient or limiting duty cycle when operating near 100 mA to maintain Tj ≤ 150 °C.
