Product details
Overview
PDTA143XE from Nexperia is a PNP 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 PDTA143XE datasheet, PDTA143XE pinout, PDTA143XE application, or PDTA143XE equivalent, this page delivers verified electrical parameters, thermal limits, pin-level circuit roles, automotive-grade reliability data, and direct alternatives for discrete logic-level switching and IC input control.
Technical Context
The PDTA143XE integrates a PNP bipolar transistor with two monolithically embedded silicon resistors: R1 (base-input resistor, 4.7 kΩ nominal) and R2 (base-emitter feedback resistor, 10 kΩ nominal), enabling single-resistor drive from microcontroller GPIOs or logic gates without external bias components.
It operates as a saturated switch with VCE(sat) ≤ −100 mV at IC = −10 mA / IB = −0.5 mA, supports input voltage range from −20 V to +7 V, and maintains hFE ≥ 50 at VCE = −5 V and IC = −10 mA - confirming robust current gain in digital on/off operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum collector-emitter voltage before breakdown; enables safe operation in 24 V automotive and industrial supply rails. |
| IO | −100 mA: Continuous output current capability; sufficient for driving LEDs, small relays, or logic inputs in compact systems. |
| R1 | 4.7 kΩ ±27%: Input bias resistor value; sets base current for predictable turn-on with standard 3.3 V/5 V logic levels. |
| R2/R1 ratio | 2.1 (typical): Ensures stable saturation and prevents unintended conduction due to leakage or noise. |
| VCE(sat) | ≤ −100 mV at IC = −10 mA: Low saturation voltage minimizes power loss and heat generation during active switching. |
| Ptot | 150 mW at Tamb ≤ 25 °C: Thermal limit for SOT416 package; requires derating above ambient temperature per published curve. |
| AEC-Q101 | Qualified: Meets stress-test requirements for automotive discrete semiconductors, supporting under-hood and body-control module deployment. |
Pinout & Package
SOT416 (SC-75) ultra-small plastic surface-mounted package with 3 leads; body dimensions 1.45 mm × 0.9 mm × 0.7 mm; optimized for high-density PCB layouts and reflow soldering only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | input (base) | Connected internally to R1; accepts logic-level drive signal; no external base resistor required. |
| 2 | GND (emitter) | Emitter terminal tied to system ground reference; serves as common return path for load current. |
| 3 | output (collector) | Switched output node; connects to load (e.g., LED anode or relay coil); sinks current when active. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 + R2 bias network | Eliminates two external resistors, reducing BOM count and layout area while ensuring consistent biasing across production lots. |
| −100 mA output current rating | Supports direct drive of moderate-current loads like status indicators, small solenoids, or interface buffers without external amplification. |
| AEC-Q101 qualification | Validated for automotive environments including temperature cycling, humidity, and mechanical shock - suitable for body electronics and infotainment subsystems. |
| Ultra-small SOT416 footprint | 0.9 mm × 1.45 mm outline enables placement in space-constrained modules such as sensor nodes and wearable ECUs. |
| VI(off) = −0.9 V (typ) | Guarantees reliable cutoff with logic-low signals down to −0.3 V, preventing false triggering in noisy industrial bus environments. |
Applications
| Automotive Body Control | Industrial Sensor Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTC143XE | NPN complement with identical R1/R2 values and SOT416 package; VCEO = +50 V, IO = +100 mA. | Used where high-side switching or sourcing current is required instead of sinking. | Select PDTC143XE when interfacing with open-collector logic or driving loads referenced to VCC. |
| BC857B,115 | Standard PNP BJT (no integrated resistors); requires external base biasing; hFE = 200–450 vs. PDTA143XE's fixed bias behavior. | Suitable for linear amplification or precision current mirroring where variable gain is needed. | Choose BC857B,115 only when design flexibility for adjustable base current or analog operation is essential. |
Compared with PDTC143XE, the NPN counterpart offers complementary topology but cannot replace PDTA143XE in sink-switching roles without circuit redesign; versus BC857B,115, PDTA143XE trades gain adjustability for reduced component count and guaranteed saturation behavior in digital logic interfaces.

FAQ
What is the maximum operating temperature for PDTA143XE?
The PDTA143XE has a junction temperature limit of 150 °C and an ambient temperature range of −65 °C to +150 °C. Its thermal resistance Rth(j-a) is 830 K/W in free air on FR4 PCB, requiring careful power derating above 25 °C ambient - full derating curves are provided in Figure 1 of the official datasheet.
Does PDTA143XE require external base resistors?
No, PDTA143XE does not require external base resistors. It integrates R1 = 4.7 kΩ (base-input) and R2 = 10 kΩ (base-emitter) internally, enabling direct connection to 3.3 V or 5 V logic outputs without additional components - a key feature confirmed in Table 1 and Section 1.2 of the Nexperia datasheet.
Is PDTA143XE pin-compatible with other SOT416 transistors?
PDTA143XE uses standard SOT416 pinning: Pin 1 = input (base), Pin 2 = GND (emitter), Pin 3 = output (collector). This matches industry-standard SOT416 layout, but functional compatibility depends on electrical characteristics - always verify VCEO, IO, and bias configuration before substitution.
What is the typical transition frequency (fT) of PDTA143XE?
The typical transition frequency fT of PDTA143XE is 180 MHz at VCE = −5 V and IC = −10 mA, as specified in Table 8 of the datasheet. This confirms suitability for high-speed digital switching up to several tens of MHz, though it is primarily optimized for DC and low-frequency logic control rather than RF applications.
Can PDTA143XE be used in place of BC847/857 series transistors?
Yes, PDTA143XE is positioned by Nexperia as a cost-saving alternative to BC847/857 series in digital switching applications. Unlike BC857B,115, it eliminates external bias resistors and simplifies layout - however, it is not a drop-in replacement for analog amplifier use cases due to fixed internal resistors and lower hFE range.
