Product details
Overview
PDTC115EEF,115 from NXP Semiconductors is an NPN resistor-equipped transistor with integrated bias resistors R1 = 100 kΩ and R2 = 100 kΩ, rated for VCEO = 50 V and IO = 20 mA DC output current, used in general-purpose switching and interface circuits on compact PCBs.
For engineers reviewing the PDTC115EEF,115 datasheet, PDTC115EEF,115 pinout, PDTC115EEF,115 application, or PDTC115EEF,115 equivalent, this discrete device serves as a space-optimized, reduced-component-count alternative to discrete BJT + resistor networks in low-power digital logic interfacing and level translation.
Technical Context
This resistor-equipped transistor integrates two precision 100 kΩ bias resistors (R1 between base and input, R2 between base and emitter) to enable single-resistor drive operation without external components. Its internal configuration supports direct connection to CMOS/TTL outputs.
The device operates as a saturated switch with VCE(sat) ≤ 150 mV at IC = 5 mA / IB = 0.25 mA and exhibits hFE ≥ 80 at VCE = 5 V and IC = 5 mA, ensuring reliable turn-on under standard logic voltage levels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - maximum collector-emitter voltage before breakdown; supports 3.3 V/5 V logic rail interfacing with margin. |
| IO (DC) | 20 mA - continuous output current capability; sufficient for driving LEDs, small relays, or logic inputs. |
| R1, R2 | 100 kΩ each - matched internal bias resistors eliminate need for external pull-up/pull-down components. |
| VCE(sat) | ≤150 mV at IC=5 mA - low saturation voltage minimizes power loss and ensures clean logic-low output. |
| hFE | ≥80 at VCE=5 V, IC=5 mA - high DC current gain enables robust switching with minimal drive current. |
| Vi(on) | 1.5 V (typ.) - input-on voltage threshold compatible with 1.8 V, 3.3 V, and 5 V logic families. |
| Ptot | 250 mW at Tamb ≤ 25 °C - thermal rating suitable for SOT490 package in standard reflow assembly. |
Pinout & Package
PDTC115EEF,115 is housed in a plastic surface-mounted SOT490 (SC-89) package measuring approximately 1.7 × 1.35 × 0.95 mm, optimized for high-density layouts and reflow soldering only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Internally connected to R1 (100 kΩ) and R2 (100 kΩ); accepts logic-level input signal directly. |
| 2 | Emitter | Common emitter node; referenced to ground or low-side return path in switching configurations. |
| 3 | Collector | Output node; sinks up to 20 mA when saturated; connects to load (e.g., LED anode, gate of downstream FET). |
Key Features
| Feature | Design Value |
|---|---|
| Built-in bias resistors | Eliminates two external 100 kΩ resistors, reducing BOM count and PCB footprint by ~2.5 mm². |
| Simplified drive interface | Accepts direct connection to CMOS/TTL outputs without level-shifting or current-limiting resistors. |
| Low VCE(sat) | Ensures <150 mV drop across collector-emitter during conduction, preserving voltage headroom in 3.3 V systems. |
| Thermal performance | Rth(j-a) = 500 K/W enables stable operation up to 150 °C junction temperature under defined mounting conditions. |
| Reflow-compatible packaging | SOT490 package qualified for lead-free reflow only-no hand-soldering or wave soldering recommended. |
Applications
| LED Driver Circuit | Microcontroller GPIO Interface |
|---|---|
Use Scenario: Driving indicator LEDs from 3.3 V microcontroller pins with current limiting. IC Role / Device Role / Timing Role: NPN switch configured in common-emitter mode, sinking LED cathode current to ground.

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 |
|---|---|---|---|
| PDTC115EK | SOT346 (SC-59) package; larger footprint (2.7 × 1.7 mm vs. 1.7 × 1.35 mm); Ptot = 250 mW same rating. | Better thermal dissipation margin due to larger pad area; less suitable for ultra-dense layouts. | Select when board space allows and higher thermal reliability is prioritized over miniaturization. |
| PDTC115EU | SOT323 (SC-70) package; slightly smaller body (2.2 × 1.35 mm) but lower Ptot = 200 mW and Rth(j-a) = 625 K/W. | Higher thermal resistance limits sustained 20 mA operation in ambient > 50 °C without derating. | Choose only for very low-duty-cycle switching or when SOT323 footprint compatibility is required. |
Compared with PDTC115EEF,115, PDTC115EK offers better thermal handling in constrained airflow environments, while PDTC115EU trades thermal margin for marginally smaller size-neither is pin-compatible due to differing pin assignments (SOT490: Pin 1=Base, Pin 2=Emitter, Pin 3=Collector; SOT323/SOT346 use Pin 1=Base, Pin 2=Collector, Pin 3=Emitter), requiring PCB layout changes.

FAQ
What is the pin configuration of PDTC115EEF,115?
PDTC115EEF,115 uses a SOT490 package with Pin 1 = Base, Pin 2 = Emitter, Pin 3 = Collector. This differs from standard SOT23/SOT323 pinouts and must be verified against the official NXP outline drawing to avoid PCB layout errors. The internal resistor network connects R1 between Pin 1 and input, and R2 between Pin 1 and Pin 2.
Can PDTC115EEF,115 replace a discrete BJT plus two 100 kΩ resistors?
Yes, PDTC115EEF,115 is functionally equivalent to an NPN transistor with 100 kΩ base-to-input (R1) and base-to-emitter (R2) resistors. It eliminates two passives and reduces layout area, but requires verifying that the SOT490 footprint and pinout match the target circuit's routing constraints.
What is the maximum operating temperature for PDTC115EEF,115?
The PDTC115EEF,115 has a maximum junction temperature (Tj) of 150 °C and an operating ambient temperature range of −65 °C to +150 °C. At 25 °C ambient, its total power dissipation is rated at 250 mW; derating is required above 25 °C per the specified thermal resistance of 500 K/W.
Is PDTC115EEF,115 compatible with lead-free reflow processes?
Yes, PDTC115EEF,115 is qualified for lead-free reflow soldering only, as stated in the datasheet. Wave soldering and hand soldering are not recommended. The SOT490 package meets JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for standard reflow profiles.
Does PDTC115EEF,115 support 1.8 V logic input drive?
Yes, PDTC115EEF,115 has a typical input-on voltage (Vi(on)) of 1.5 V at IC = 1 mA, making it compatible with 1.8 V logic families. Its guaranteed minimum hFE of 80 at 5 V VCE and 5 mA IC ensures reliable saturation even with marginal drive current from low-voltage sources.
