Product details
Overview
PDTA143TMB from Nexperia is a PNP resistor-equipped transistor (RET) in a DFN1006B-3 (SOT883B) package, rated for −50 V VCEO, −100 mA output current, and featuring a built-in 4.7 kΩ input bias resistor (R1) with R2 open. It functions as a digitally controlled switch in low-power logic interface and peripheral driver circuits, commonly used in mobile and automotive control modules.
For engineers reviewing the PDTA143TMB datasheet, PDTA143TMB pinout, PDTA143TMB application, or PDTA143TMB equivalent, key selection criteria include its AEC-Q101 qualification, ultra-small 1.0 mm × 0.6 mm footprint, −150 mV VCEsat at −5 mA/−0.25 mA drive, and integrated bias network eliminating external resistors in digital switching designs.
Technical Context
This PNP RET integrates a single base-input resistor (R1 = 4.7 kΩ nominal) and no feedback resistor (R2 = open), enabling direct TTL/CMOS-level input drive without external biasing. Its simplified three-terminal structure-input (base), GND (emitter), output (collector)-supports unidirectional switching with fixed gain architecture.
The device operates within −65 °C to +150 °C ambient range, delivers hFE ≥ 200 at −1 mA collector current, and maintains ≤ 3 pF collector capacitance at −10 V VCB, supporting stable high-frequency digital switching up to 180 MHz fT in its internal transistor core.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum safe collector-emitter voltage under open-base condition; defines off-state blocking capability in low-voltage rail switching. |
| IO | −100 mA: Continuous DC output current rating; supports driving LEDs, small relays, or logic inputs without thermal derating at 25 °C. |
| R1 | 4.7 kΩ (typ): Integrated base-input resistor enables direct connection to 3.3 V or 5 V logic outputs; eliminates need for external pull-up/down components. |
| VCEsat | −150 mV (max) at IC = −5 mA, IB = −0.25 mA: Low saturation voltage minimizes power loss and heat generation in active-switching applications. |
| hFE | ≥ 200 at VCE = −5 V, IC = −1 mA: Sufficient DC current gain ensures reliable turn-on with minimal input drive current. |
| fT | 180 MHz (typ): Transition frequency of internal transistor core; supports fast digital edge response in signal routing and enable/disable functions. |
| Cc | 3 pF (max) at VCB = −10 V: Low collector capacitance reduces signal delay and crosstalk in high-density PCB layouts. |
Pinout & Package
DFN1006B-3 (SOT883B) is a leadless, ultra-small surface-mount plastic package measuring 1.0 mm × 0.6 mm × 0.37 mm with 0.35 mm pitch and three solder lands. Its low profile (0.37 mm height) and AEC-Q101 qualification support space-constrained automotive and portable electronics assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level voltage to activate PNP switching action; no external bias required. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; serves as common reference and current return path for switched load. |
| 3 | Output (collector) | Switched high-side output node; sinks current from load connected between VCC and this pin when active. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 bias resistor | 4.7 kΩ ±28% tolerance eliminates discrete resistor placement, reducing BOM count and PCB area by ~2 components per channel. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing; suitable for under-hood and infotainment subsystems. |
| Ultra-small DFN1006B-3 footprint | 1.0 mm × 0.6 mm body size with 0.35 mm pitch enables routing in <1.5 mm² board space-ideal for wearables and compact sensor nodes. |
| Low VCEsat at low drive | −150 mV saturation voltage with only −0.25 mA base current enables efficient switching from 3.3 V GPIOs without additional level-shifting circuitry. |
Applications
| Mobile Peripheral Control | Automotive 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 |
|---|---|---|---|
| PDTC143TMB | NPN complement with identical R1 = 4.7 kΩ, same DFN1006B-3 package, but opposite polarity and +50 V VCEO. | Suitable for low-side switching where emitter connects to ground; not interchangeable in high-side configurations. | Select PDTC143TMB only when circuit topology requires NPN sink behavior and supply rail referencing differs. |
| EMH11T2R | PNP RET with R1 = 10 kΩ, R2 = 10 kΩ, higher VCEO = −60 V, and larger SOT-723 package (1.2 × 0.8 mm). | Supports dual-resistor bias networks for precise gain control and improved noise immunity in industrial analog interfaces. | Choose EMH11T2R when design requires feedback resistor (R2) for hysteresis or tighter input threshold control. |
Compared with PDTC143TMB and EMH11T2R, PDTA143TMB offers optimal space efficiency and lowest profile for high-density mobile designs, while its single-R1 architecture simplifies logic-level interfacing where feedback stabilization is unnecessary.

FAQ
Is PDTA143TMB suitable for high-frequency switching above 10 MHz?
Yes - its internal transistor exhibits a typical transition frequency (fT) of 180 MHz, and measured collector capacitance is only 3 pF at −10 V VCB. These parameters support clean digital edge response in enable/disable and data-routing functions up to 25 MHz without significant rise/fall time degradation.
What is the maximum allowable ambient temperature during continuous operation?
The device is rated for continuous operation from −65 °C to +150 °C ambient temperature. At full 100 mA output current, thermal derating begins above 25 °C ambient per the FR4 PCB power curve - total power dissipation must stay below 250 mW at 25 °C, decreasing linearly to zero at 150 °C junction temperature.
Can PDTA143TMB be used in bidirectional signal paths?
No - it is a unidirectional PNP switch with fixed terminal roles: Pin 1 is input (base), Pin 2 is GND (emitter), Pin 3 is output (collector). The internal resistor network and polarity prevent reverse current conduction or AC coupling; it functions strictly as a high-side digital switch.
Does the "R2 = open" specification mean the second resistor is omitted or disconnected?
"R2 = open" means no internal feedback resistor is present between base and emitter - the device contains only R1 (4.7 kΩ) from input to base. This configuration provides basic digital on/off control without hysteresis or gain stabilization, making it ideal for simple logic-level interfacing rather than precision analog switching.
