Product details
Overview
PDTC143XEF,115 from Nexperia is an NPN resistor-equipped transistor (RET) in SOT416 (SC-75) surface-mount package, designed for digital switching applications with built-in bias resistors R1 = 4.7 kΩ and R2 = 10 kΩ, 50 V VCEO, 100 mA IO, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PDTC143XEF,115 datasheet, PDTC143XEF,115 pinout, PDTC143XEF,115 application, or PDTC143XEF,115 equivalent, this device serves as a space- and cost-optimized replacement for discrete BJT + resistor networks in IC input control and low-power load switching where simplified layout and reduced component count are critical.
Technical Context
The PDTC143XEF,115 integrates an NPN transistor with two monolithically embedded silicon resistors - R1 (base-input resistor) and R2 (base-emitter feedback resistor) - enabling single-pin digital drive without external biasing. Its R2/R1 ratio of 2.1 ensures stable saturation under varying temperature and process conditions.
It operates as a digital switch with VI(on) = 1.5 V (typ.) at IC = 20 mA and VI(off) = 0.9 V (typ.) at IC = 100 µA, supporting direct interfacing with 1.8 V, 3.3 V, and 5 V logic families while maintaining guaranteed turn-off margin across −40 °C to +150 °C ambient range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports 24 V automotive supply rail switching with safety margin. |
| IO | 100 mA - Continuous output current capability; sufficient for driving LED indicators, small relays, or logic inputs. |
| R1 | 4.7 kΩ (typ.) - Input bias resistor sets base current; enables direct microcontroller GPIO drive without external resistor. |
| R2/R1 | 2.1 (typ.) - Feedback resistor ratio ensures reliable saturation and prevents thermal runaway during sustained conduction. |
| VCE(sat) | 100 mV (max.) at IC = 10 mA, IB = 0.5 mA - Low saturation voltage minimizes power loss and self-heating in switching mode. |
| hFE | 50 (min.) at VCE = 5 V, IC = 10 mA - Guaranteed DC current gain ensures predictable switching behavior in digital on/off operation. |
| fT | 230 MHz (typ.) - Transition frequency confirms suitability for high-speed digital switching up to ~10–20 MHz edge rates. |
Pinout & Package
SOT416 (SC-75) ultra-small plastic surface-mounted package, 3-lead, body size 1.45 mm × 0.9 mm × 0.7 mm, optimized for high-density PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | input (base) | Connected internally to R1; accepts logic-level drive signal directly from MCU or gate output. |
| 2 | GND (emitter) | Emitter tied to ground reference; provides common return path for load current and bias network. |
| 3 | output (collector) | Switched output node; connects to load (e.g., LED cathode or relay coil) with current sourced from VCC. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 + R2 bias network | Eliminates two external resistors, reducing BOM count and PCB footprint by >30% vs. discrete BJT + resistor solution. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD (HBM ≥8 kV), enabling use in engine control, body electronics, and ADAS modules. |
| Low VCE(sat) | ≤100 mV ensures <1 mW conduction loss at 10 mA, critical for thermally constrained modules and battery-powered systems. |
| Wide operating temperature | −65 °C to +150 °C junction range supports under-hood and industrial environments without derating. |
| Reflow-only soldering | Compatible with standard lead-free reflow profiles (J-STD-020), eliminating wave soldering compatibility concerns. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN digital switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTC143XT,215 | SOT23 package (3.0 mm × 1.4 mm); higher Ptot = 250 mW; same R1/R2 values and electrical specs. | Better thermal performance and mechanical robustness; suitable for higher-current or higher-reliability industrial designs. | Select when board space allows larger footprint and thermal dissipation >150 mW is required. |
| BC847B,215 | Standard NPN BJT (no integrated resistors); requires external base resistor; hFE = 200–450 (wider spread); no AEC-Q101 rating. | Higher gain but less predictable switching thresholds; not qualified for automotive use without additional validation. | Choose only for non-automotive, cost-sensitive designs where external resistor placement is acceptable and qualification overhead is justified. |
Compared with PDTC143XEF,115, the PDTC143XT,215 offers superior thermal handling in the same functional role, while BC847B,215 demands external bias design and lacks automotive qualification - making PDTC143XEF,115 the optimal choice for space-constrained, AEC-Q101-compliant digital switching.

FAQ
What is the package type and dimensions of PDTC143XEF,115?
The PDTC143XEF,115 uses the SOT416 (SC-75) ultra-small surface-mount package with body dimensions of 1.45 mm × 0.9 mm × 0.7 mm and a 0.65 mm pin pitch. Its compact footprint supports high-density PCB layouts in space-constrained automotive and portable electronics applications, and it is compatible with standard 4 mm pitch tape-and-reel handling (ordering code suffix -115).
Is PDTC143XEF,115 qualified for automotive applications?
Yes, PDTC143XEF,115 is AEC-Q101 qualified for discrete semiconductors, having passed stress tests including temperature cycling, high-temperature reverse bias (HTRB), and human-body-model ESD (≥8 kV). This qualification enables its use in automotive body control, lighting, and infotainment systems without additional component-level reliability testing.
What are the key electrical differences between PDTC143XEF,115 and PDTC143XT,215?
Both PDTC143XEF,115 and PDTC143XT,215 share identical electrical characteristics - R1 = 4.7 kΩ, R2/R1 = 2.1, VCEO = 50 V, IO = 100 mA - but differ in package: PDTC143XEF,115 uses SOT416 (1.45 mm × 0.9 mm), while PDTC143XT,215 uses SOT23 (3.0 mm × 1.4 mm) with higher power dissipation (250 mW vs. 150 mW) and improved thermal resistance (500 K/W vs. 830 K/W).
Can PDTC143XEF,115 replace BC847-type transistors directly?
PDTC143XEF,115 is a cost-saving alternative to BC847/857 series in digital switching applications, but it is not a pin-to-pin drop-in replacement due to integrated bias resistors and different pin configuration. It replaces the BC847 plus two external resistors, simplifying circuit design - however, schematic and layout changes are required to remove those external components and route to the RET's three-terminal interface.
What is the maximum ambient temperature for continuous operation of PDTC143XEF,115?
The PDTC143XEF,115 supports continuous operation from −65 °C to +150 °C ambient temperature, with a maximum junction temperature of 150 °C. At elevated ambient temperatures, power dissipation must be derated per the published thermal curves - for example, at 85 °C ambient, maximum allowable Ptot drops to approximately 75 mW for the SOT416 package.
