Product details
Overview
PDTA143TE from Nexperia is a PNP resistor-equipped transistor with integrated 4.7 kΩ base bias resistor (R1), open R2 configuration, −50 V VCEO, −100 mA IO, and SOT416 (SC-75) package - used for compact logic-level switching in portable power management and signal interface circuits.
For engineers reviewing the PDTA143TE datasheet, PDTA143TE pinout, PDTA143TE application, or PDTA143TE equivalent, key selection criteria include its single-base-resistor topology, −50 V breakdown rating, thermal resistance of 833 K/W in SOT416, and compatibility with reflow-only assembly per JEDEC J-STD-020.
Technical Context
This device integrates a monolithic PNP bipolar junction transistor with a precision 4.7 kΩ input bias resistor (R1) and no second resistor (R2 = open), enabling direct connection to CMOS/TTL logic without external bias components. It operates as a saturated switch with guaranteed −150 mV VCEsat at −5 mA IC/−0.25 mA IB.
Designed for low-power digital interface applications, it supports ambient temperatures from −65 °C to +150 °C and requires reflow soldering only - no wave or hand-soldering - due to thermal constraints in the ultra-small SOT416 package (1.0 × 0.6 × 0.5 mm body).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - maximum safe collector-emitter voltage before breakdown; enables use in 24 V rail switching with margin. |
| IO (DC) | −100 mA - continuous output current capability; sufficient for driving LEDs, small relays, or logic buffers. |
| R1 | 4.7 kΩ (3.3–6.1 kΩ range) - integrated base bias resistor; eliminates need for external pull-up/pull-down in inverter or level-shift circuits. |
| VCEsat | −150 mV max at −5 mA IC/−0.25 mA IB - ensures low conduction loss and minimal self-heating in battery-powered systems. |
| Rth j-a | 833 K/W - high thermal resistance due to SOT416 package size; limits usable DC power to ~150 mW at Tamb ≤ 25 °C. |
| hFE | 200 min at −5 V VCE/−1 mA IC - provides robust current gain for reliable saturation under varying load conditions. |
Pinout & Package
Package: SOT416 (SC-75), plastic surface-mounted, 3-lead, dimensions 1.0 × 0.6 × 0.5 mm - optimized for high-density PCB layouts in space-constrained wearables and IoT sensors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Input node connected internally to 4.7 kΩ resistor; accepts TTL/CMOS logic-high (≤ −0.7 V) to turn on PNP switch. |
| 2 | Emitter | Common reference terminal; tied to positive supply rail in high-side switch configuration. |
| 3 | Collector | Output node; sinks current to load when active; connects to load return path (e.g., ground or low-voltage rail). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 bias resistor | 4.7 kΩ ±28% tolerance reduces BOM count by one passive component and eliminates layout error risk in base drive paths. |
| R2 = open configuration | No second resistor simplifies design for unidirectional switching where emitter-follower or fixed-gain operation is not required. |
| Reflow-only assembly compliance | Validated per JEDEC J-STD-020; avoids thermal damage during manufacturing - critical for thin FR4 boards with tight copper pour. |
| −5 V VEBO rating | Enables safe operation with standard 3.3 V or 5 V logic inputs without clamping diodes or level shifters. |
Applications
| LED Driver Circuit | Microcontroller GPIO Expander |
|---|---|
Use Scenario: Driving indicator LEDs from 3.3 V MCU outputs in handheld medical devices. IC Role / Device Role / Timing Role: High-side PNP switch controlling LED anode connection to VCC; base driven directly by MCU GPIO. Use Value: Eliminates external base resistor, saving 0.4 mm² PCB area and reducing assembly cost in volume production. | Use Scenario: Adding two extra active-low enable lines to an STM32-based sensor hub with limited GPIOs. IC Role / Device Role / Timing Role: Logic-level inverter translating MCU's high-active signals into low-active control for peripheral ICs. Use Value: Achieves clean −150 mV VCEsat with <1 μs turn-off delay, supporting 10 kHz enable/disable cycling without shoot-through. |
| Low-Power Power Sequencing | USB-C Port Detection Interface |
Use Scenario: Enabling 1.8 V LDO only after 3.3 V rail stabilizes in battery-powered edge node. IC Role / Device Role / Timing Role: Voltage-controlled switch activating EN pin of downstream regulator based on upstream rail status. Use Value: Leverages −50 V VCEO margin to tolerate transient overshoot on 3.3 V rail while maintaining <100 nA leakage at standby. | Use Scenario: Detecting CC line pull-down in USB-C receptacle to determine plug orientation and source capability. IC Role / Device Role / Timing Role: Level translator interfacing 5 V CC detection circuitry to 3.3 V microcontroller ADC input. Use Value: Uses open-R2 topology to avoid loading CC line; R1 sets precise bias point for accurate voltage division without calibration. |
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 |
|---|---|---|---|
| PDTC143TE | NPN complement with identical R1 = 4.7 kΩ, same SOT416 package, but opposite polarity and logic drive requirement. | Requires inverted control signal; suitable for low-side switching instead of high-side. | Select PDTC143TE when load must be switched to ground rather than VCC, and MCU GPIO can sink current. |
| EMH11T2R | PNP RET with R1 = 10 kΩ, R2 = 10 kΩ (dual-resistor), SOT-723 package (smaller footprint), 200 mW Ptot. | Supports bias-stable amplifier mode via R2 feedback; less suitable for simple on/off switching. | Choose EMH11T2R only if dual-resistor bias network is needed for linear operation or improved temperature stability. |
Compared with PDTC143TE and EMH11T2R, the PDTA143TE offers optimal simplicity for high-side digital switching: its single-R1 architecture minimizes component count, its −50 V rating exceeds typical 24 V industrial interfaces, and its SOT416 footprint balances density with manufacturability.

FAQ
What is the pin configuration of the PDTA143TE?
The PDTA143TE uses a SOT416 package with three terminals: Pin 1 is Base (connected to internal 4.7 kΩ resistor), Pin 2 is Emitter, and Pin 3 is Collector. This pinout is standardized across all PDTA143T-series variants in SOT416, confirmed in the official Nexperia datasheet Figure 3 "Simplified outline and symbol".
Can the PDTA143TE be used in linear amplifier mode?
The PDTA143TE is characterized and qualified for switching operation, with hFE specified only at −1 mA IC and VCE = −5 V. Its open-R2 topology lacks emitter feedback, limiting bias stability for analog amplification; Nexperia does not specify linearity, distortion, or frequency response - so PDTA143TE is not recommended for linear amplifier use.
What is the maximum allowable PCB temperature during reflow for PDTA143TE?
The PDTA143TE requires reflow soldering only, per datasheet Note 2 in Limiting Values. Peak reflow temperature must not exceed 260 °C for ≤ 30 seconds, consistent with IPC/JEDEC J-STD-020D for small-body packages. Exceeding this risks delamination or internal bond wire failure in the SOT416 package.
Does the PDTA143TE have built-in ESD protection?
No ESD protection rating (e.g., HBM or CDM) is specified for PDTA143TE in the datasheet. The device contains no integrated protection diodes; system-level ESD safeguards (e.g., TVS on base line) are required if deployed in environments with >2 kV human-body-model exposure risk.
Is the PDTA143TE RoHS and REACH compliant?
Yes - PDTA143TE complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Nexperia confirms full compliance in its material declarations, and the device carries the "RoHS-compliant" marking on packaging per datasheet footnote * on page 2.
