Product details
Overview
PDTA143EQB-Q from Nexperia is a 50 V, 100 mA PNP resistor-equipped transistor (RET) in a DFN1110D-3 (SOT8015) leadless package with side-wettable flanks. It integrates 4.7 kΩ input and 4.7 kΩ base-emitter bias resistors, delivers −100 mA output current, exhibits −100 mV VCE(sat) at IC = −10 mA/IB = −0.5 mA, and is AEC-Q101 qualified for automotive digital switching applications.
For engineers reviewing the PDTA143EQB-Q datasheet, PDTA143EQB-Q pinout, PDTA143EQB-Q application, or PDTA143EQB-Q equivalent, this page provides verified pin functions, real-world switching use cases, thermal derating curves, AOI-compatible solder joint validation, and direct alternatives to BC857-Q series transistors.
Technical Context
This PNP RET uses an integrated bipolar transistor with two monolithically embedded resistors: R1 (4.7 kΩ) between base and input terminal, and R2 (4.7 kΩ) between base and emitter. Its fixed R2/R1 ratio of 1.0 enables predictable turn-on/off thresholds without external bias network design.
The device operates with −50 V VCEO, supports −100 mA continuous output, achieves −100 mV saturation voltage under defined drive conditions, and maintains stable hFE ≥ 30 at VCE = −5 V and IC = −10 mA - enabling reliable digital logic-level interfacing and load control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum collector-emitter voltage before breakdown; ensures robust operation in 24 V automotive supply rails with margin. |
| IO | −100 mA: Continuous output current capability; sufficient for driving LEDs, small relays, or logic inputs. |
| VCE(sat) | −100 mV at IC = −10 mA / IB = −0.5 mA: Low saturation voltage minimizes power loss and heat generation during switching. |
| R1 / R2 | 4.7 kΩ / 4.7 kΩ: Integrated bias resistors eliminate need for external components, reducing BOM count and PCB area. |
| hFE | ≥30 at VCE = −5 V, IC = −10 mA: Sufficient DC current gain to ensure full saturation with standard logic-level drive. |
| Tj(max) | 150 °C: Maximum junction temperature rating supports operation in under-hood automotive environments. |
Pinout & Package
DFN1110D-3 (SOT8015) is a 3-terminal, ultra-thin (0.48 mm height), leadless surface-mount package with side-wettable flanks for automated optical inspection (AOI) of solder joints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Accepts logic-level control signal; internally connected to R1 (4.7 kΩ) leading to transistor base. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; also connects to R2 (4.7 kΩ) for internal base biasing. |
| 3 | Output (collector) | Switched high-side output node; sinks current when device is active, suitable for low-side load switching. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias resistors | Eliminates 2 external resistors per switch, reducing component count and layout complexity in digital interface circuits. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22 standards. |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder fillets on all three terminals, improving manufacturing yield verification. |
| Ultra-low profile | 0.48 mm max height allows use in space-constrained modules such as ADAS sensors and infotainment control units. |
Applications
| Automotive Door Module Control | Industrial PLC Input Conditioning |
|---|---|
|
Use Scenario: Switching 12 V indicator LEDs and small solenoids in vehicle door control units. IC Role / Device Role / Timing Role: PNP RET acts as a grounded-emitter switch, sinking current from loads connected to battery rail. Use Value: −100 mV VCE(sat) limits power dissipation to <1 mW at 10 mA, eliminating heatsinking in compact modules. |
Use Scenario: Level-shifting and current-limiting 24 V industrial sensor signals into 3.3 V microcontroller GPIOs. IC Role / Device Role / Timing Role: Digital interface buffer providing galvanic isolation via discrete switching, not optocoupler replacement. Use Value: Built-in 4.7 kΩ resistors enable direct connection to open-collector outputs without pull-up or bias network redesign. |
| Consumer Appliance Power Sequencing | Medical Diagnostic Equipment Status Indication |
|
Use Scenario: Enabling sequential power-up of subsystems (e.g., display backlight, motor driver, MCU) in smart home appliances. IC Role / Device Role / Timing Role: Low-current PNP switch controlling enable lines of downstream LDOs or gate drivers. Use Value: −50 V VCEO withstands transient spikes on 24 V supply rails, ensuring sequencing integrity during brown-out recovery. |
Use Scenario: Driving status LEDs and audible alert indicators in portable diagnostic devices requiring low EMI and high reliability. IC Role / Device Role / Timing Role: Load switch for visual/audible feedback circuits operating from isolated 3.3 V or 5 V supplies. Use Value: AEC-Q101 qualification confirms long-term stability under thermal cycling and humidity exposure typical in clinical environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP digital switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTC143EQB-Q | NPN complement with identical R1/R2 (4.7 kΩ), same package and AEC-Q101 rating. | Requires inverted logic drive and high-side load configuration instead of low-side sink. | Select when interfacing with open-drain outputs or when sourcing current from VCC is required. |
| BC857B-Q | Discrete PNP transistor (no built-in resistors); hFE = 220–475; requires external base bias network. | Higher gain but adds 2 passive components and layout area; no AOI-optimized package. | Choose only if variable gain or adjustable switching threshold is needed beyond fixed RET behavior. |
Compared with PDTC143EQB-Q, PDTA143EQB-Q enables simpler low-side switching with non-inverted logic; versus BC857B-Q, it reduces bill-of-materials and improves manufacturability through integrated biasing and AOI-ready packaging.

FAQ
What is the maximum ambient temperature for continuous operation?
The PDTA143EQB-Q supports continuous operation from −55 °C to +150 °C ambient temperature. At Tamb = 125 °C, its power derating curve shows usable Ptot ≈ 200 mW on standard FR4 PCBs, enabling deployment in engine bay or industrial control enclosures without forced cooling.
Can this part replace BC857B in existing designs without layout changes?
No - PDTA143EQB-Q has different pinout (input/base on Pin 1, GND/emitter on Pin 2, collector on Pin 3) and integrated resistors, so direct footprint replacement is not possible. A redesign is required to remove external base resistors and verify logic polarity compatibility due to PNP RET architecture.
Is the DFN1110D-3 package compatible with standard reflow profiles?
Yes - the SOT8015 package is qualified for JEDEC J-STD-020 moisture sensitivity level 1 and supports standard lead-free reflow profiles (peak 260 °C). The side-wettable flanks allow post-reflow AOI verification of all three solder joints using industry-standard vision systems.
What is the off-state input voltage range for guaranteed turn-off?
The guaranteed off-state input voltage (VI(off)) is −1.1 V to −0.5 V at VCE = −30 V and IC = −100 µA. This ensures reliable cutoff when driven by 0 V logic or pulled below −0.5 V, preventing unintended conduction in noisy automotive environments.
