Product details
Overview
PDTC144VT,215 from Nexperia is an NPN resistor-equipped transistor (RET) in SOT23 package, featuring integrated bias resistors R1 = 47 kΩ and R2 = 10 kΩ (R2/R1 ≈ 0.21), VCEO = 50 V, IO = 100 mA DC, and VCE(sat) ≤ 150 mV at IC = 10 mA / IB = 0.5 mA. It serves as a single-chip digital switch in low-voltage logic interface circuits, eliminating external base resistors in microcontroller GPIO-driven loads.
For engineers reviewing the PDTC144VT,215 datasheet, PDTC144VT,215 pinout, PDTC144VT,215 application, or PDTC144VT,215 equivalent, this device is selected for space-constrained 3.3 V/5 V digital switching where component count reduction, consistent turn-on threshold (VI(on) = 3.8 V typ), and guaranteed saturation under defined drive conditions are critical.
Technical Context
This RET integrates two precision thin-film resistors to form a voltage-divider bias network directly at the base terminal, enabling direct connection to CMOS/TTL logic outputs without discrete pull-up/down components. Its internal R1–R2 topology ensures predictable current gain (hFE ≥ 40 at IC = 5 mA) and stable switching thresholds across temperature (−40 °C to +150 °C).
The device operates as a saturated switch with fixed input impedance (~47 kΩ), delivering low VCE(sat) and fast turn-off due to R2's emitter-base shunt path. It is not intended for linear amplification but optimized for on/off control in digital signal routing, LED driving, and small-signal load switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports 3.3 V/5 V/12 V logic-level switched loads. |
| IO (DC) | 100 mA - Continuous collector current capability; sufficient for driving LEDs, relays, or logic inputs. |
| R1 | 47 kΩ ±28% - Input bias resistor; sets base current when driven from 3.3 V/5 V logic, enabling resistorless interface. |
| R2/R1 ratio | 0.21 ±21% - Ratio defining feedback fraction; ensures reliable saturation and prevents deep cutoff during noise transients. |
| VCE(sat) | ≤150 mV at IC=10 mA/IB=0.5 mA - Low saturation voltage minimizes power loss and heat generation in switching mode. |
| VI(on) | 3.8 V typ at IC=2 mA - Guaranteed turn-on threshold compatible with 3.3 V CMOS outputs (VOH ≥ 3.6 V). |
| Ptot | 250 mW at Tamb ≤25 °C - Power dissipation limit in SOT23 package; requires thermal derating above 25 °C ambient. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package, 3-lead, 1.3 mm × 2.9 mm × 1.0 mm body height; standard JEDEC outline with gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1 (47 kΩ) and R2 (10 kΩ); accepts logic-level drive; no external resistor needed. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; R2 connects between base and emitter for active pull-down during turn-off. |
| 3 | Output (collector) | Switched output node; sinks current from load (e.g., LED anode or relay coil) to ground via emitter. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in bias resistors R1/R2 | Eliminates two external SMT resistors per switch, reducing BOM count and PCB area in multi-channel interfaces. |
| Guaranteed saturation | VCE(sat) ≤ 150 mV ensures minimal voltage drop and power loss when switching 10 mA loads. |
| Logic-compatible VI(on) | 3.8 V typical enables direct drive from 3.3 V microcontrollers without level-shifting circuitry. |
| Thermal robustness | Rated junction temperature up to 150 °C supports operation in industrial environments with limited airflow. |
Applications
| Microcontroller GPIO Interface | LED Indicator Driver |

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 |
|---|---|---|---|
| PDTC124ET,215 | R1 = 22 kΩ, R2 = 47 kΩ → higher base current, lower VI(on) (2.2 V typ) | Better suited for 1.8 V/2.5 V logic families; less margin for 3.3 V noise immunity | Select when driving from low-voltage ASICs or battery-powered sensors with sub-3 V outputs. |
| EMD100100R | Complementary PNP RET; same R1/R2 values but inverted polarity; VECO = 50 V, IO = 100 mA | Used for high-side switching or complementary push-pull stages; not interchangeable without circuit redesign | Choose for source-driving configurations (e.g., PMOS gate control) where emitter must connect to VCC. |
Compared with PDTC124ET,215 and EMD100100R, PDTC144VT,215 offers optimal balance of 3.3 V compatibility, saturation margin, and layout simplicity for low-side switching-making it preferred for MCU-peripheral interfacing where input voltage stability and thermal headroom are prioritized over ultra-low-VI(on).

FAQ
What is the maximum continuous collector current for PDTC144VT,215?
The absolute maximum DC collector current is 100 mA, as specified in Table 6 (Limiting Values). At this current, VCE(sat) remains ≤150 mV when driven with IB = 0.5 mA, and total power dissipation stays within the SOT23-rated 250 mW limit at Tamb ≤25 °C. Derating is required above 25 °C ambient.
Can PDTC144VT,215 be used with 1.8 V logic inputs?
No-its typical VI(on) is 3.8 V, with minimum guaranteed value of 3.1 V, making it incompatible with reliable turn-on from 1.8 V logic. For 1.8 V systems, consider PDTC114ET,215 (VI(on) = 0.95 V typ) or PDTC124ET,215 (VI(on) = 2.2 V typ), both offering lower input thresholds.
Does PDTC144VT,215 require an external pull-down resistor on the base?
No-R2 (10 kΩ) is internally connected between base and emitter, providing active pull-down during turn-off. This eliminates the need for an external base-emitter resistor and ensures rapid, deterministic turn-off even with floating or high-impedance drive sources.
How does the R2/R1 ratio affect switching behavior?
The R2/R1 ratio of 0.21 establishes the feedback fraction that stabilizes the base voltage during conduction and accelerates turn-off by shunting residual base charge to emitter. This ratio ensures hFE-independent saturation and prevents latch-up in noisy environments, unlike bare transistors requiring careful external resistor selection.
