Product details
Overview
PDTC143XE,115 from Nexperia is an NPN resistor-equipped transistor (RET) in SOT416 (SC-75) 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 PDTC143XE,115 datasheet, PDTC143XE,115 pinout, PDTC143XE,115 application, or PDTC143XE,115 equivalent, this page delivers verified electrical parameters, thermal limits, pin-level circuit roles, automotive-grade reliability data, and direct alternatives for load switching and IC input control in space-constrained designs.
Technical Context
The PDTC143XE,115 integrates a monolithic NPN transistor with two precision on-die resistors (R1 = 4.7 kΩ, R2 = 10 kΩ) to form a single-input, single-output digital switch. It operates as a saturated switch with guaranteed VCE(sat) ≤ 100 mV at IC = 10 mA / IB = 0.5 mA and supports input voltage ranges from −7 V to +20 V.
Its 3-pin SOT416 package enables ultra-small footprint placement, and its AEC-Q101 qualification confirms suitability for automotive ambient temperature ranges (−65 °C to +150 °C) and transient stress conditions without external bias network components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V automotive and industrial logic-level switching. |
| IO | 100 mA - Continuous output current capability; sufficient for driving LEDs, small relays, and logic inputs. |
| R1 | 4.7 kΩ ±27% - Input bias resistor; sets base current for predictable turn-on without external components. |
| R2/R1 | 2.1 (typical) - Internal feedback ratio; ensures stable saturation and prevents unintended conduction during noise transients. |
| VCE(sat) | ≤100 mV at IC = 10 mA / IB = 0.5 mA - Low saturation voltage minimizes power loss and self-heating in high-duty-cycle switching. |
| Ptot | 150 mW at Tamb ≤ 25 °C - Total power dissipation limit; defines thermal derating curve for PCB layout planning. |
| Tj | 150 °C - Maximum junction temperature; supports operation in under-hood automotive environments. |
Pinout & Package
SOT416 (SC-75) plastic surface-mounted package; 3-lead, ultra-small outline measuring 1.75 mm × 0.95 mm × 0.7 mm (L × W × H), optimized for high-density PCB layouts and reflow soldering only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | input (base) | Connected internally to R1; accepts TTL/CMOS-compatible logic signals directly without series resistor. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; serves as common return path for switched load current. |
| 3 | output (collector) | Switched output node; connects to load (e.g., LED anode, relay coil) with current sourced from VCC. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1/R2 bias network | Eliminates 2 external resistors, reducing BOM count and PCB area while ensuring consistent switching thresholds. |
| AEC-Q101 qualification | Validated for automotive applications including engine control modules, body electronics, and ADAS sensors. |
| Low VCE(sat) | Guaranteed ≤100 mV enables efficient switching of 3.3 V and 5 V logic loads with minimal voltage drop. |
| Wide input voltage range | Supports −7 V to +20 V input swing, accommodating noise margins and transient overvoltage in industrial systems. |
| Ultra-small SOT416 footprint | 0.95 mm width allows placement in tight spaces where SOT23 or SOT323 are too large. |

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 × 1.4 mm); higher Ptot = 250 mW; same R1/R2 values and electrical specs. | Better thermal performance in moderate-power applications; requires larger PCB footprint than PDTC143XE,115. | Select when higher continuous current handling or easier manual assembly is prioritized over miniaturization. |
| BC847B,215 | Standard NPN BJT (no built-in resistors); requires external base resistor; hFE = 200–450 vs. RET's fixed gain behavior. | Greater design flexibility but increases component count and sensitivity to layout parasitics. | Select when precise analog gain control or multi-stage amplification is needed instead of simple digital on/off switching. |
Compared with PDTC143XT,215, the PDTC143XE,115 offers 44% smaller footprint at the cost of 40% lower power dissipation; compared with BC847B,215, it trades external resistor dependency for deterministic switching thresholds and reduced layout sensitivity.

FAQ
What is the maximum operating temperature for PDTC143XE,115?
The PDTC143XE,115 has a maximum junction temperature (Tj) of 150 °C and an ambient temperature range of −65 °C to +150 °C. Its thermal resistance Rth(j-a) is 830 K/W on FR4 PCB, so sustained operation above 85 °C ambient requires careful power derating-e.g., at 100 °C ambient, max usable Ptot drops to ~75 mW. PDTC143XE,115 maintains full specification compliance across this full range when mounted per recommended footprint.
Is PDTC143XE,115 pin-compatible with other PDTC143X variants?
Yes-PDTC143XE,115 shares identical 3-pin configuration (pin 1 = input, pin 2 = emitter/GND, pin 3 = collector/output) with PDTC143XM, PDTC143XT, and PDTC143XU. However, package dimensions differ: SOT416 (PDTC143XE,115) is not mechanically interchangeable with SOT23 or SOT323 without PCB redesign. PDTC143XE,115 uses the same pinout as all members of the PDTC143X series.
Does PDTC143XE,115 require an external base resistor?
No-PDTC143XE,115 integrates R1 = 4.7 kΩ and R2 = 10 kΩ internally, eliminating the need for external base biasing components. This simplifies circuit design, reduces pick-and-place steps, and improves consistency across production units. The input (pin 1) accepts direct connection to 3.3 V or 5 V logic outputs, and VI(on) is specified at 1.5 V (typical) for reliable turn-on.
What is the marking code for PDTC143XE,115 on the device body?
The top-side marking for PDTC143XE,115 is "34", as confirmed in Table 5 of the official datasheet. This 2-character code is laser-etched on the package surface and is used for visual identification and traceability during assembly and inspection. No date code, lot code, or manufacturing site identifier appears in the primary marking-only "34" denotes the PDTC143XE type.
Can PDTC143XE,115 be used in linear amplifier configurations?
No-PDTC143XE,115 is optimized and characterized exclusively for digital switching operation in saturation/cutoff modes. Its internal resistor network fixes bias conditions, and hFE is not specified for linear region use. For analog amplification, Nexperia recommends standard BJTs like BC847B or BC846B. PDTC143XE,115 should only be used as a switch, not as a linear gain stage.
