Product details
Overview
PDTA143ZMB from Nexperia is a PNP resistor-equipped transistor (RET) in a DFN1006B-3 (SOT883B) package, designed as a single-chip solution for digital switching with integrated bias resistors R1 = 4.7 kΩ and R2 = 47 kΩ. It delivers −100 mA output current, −50 V VCEO, and AEC-Q101 qualification, enabling compact, reliable control of low-current peripheral loads in space-constrained mobile and automotive modules.
For engineers reviewing the PDTA143ZMB datasheet, PDTA143ZMB pinout, PDTA143ZMB application, or PDTA143ZMB equivalent, this device serves as a drop-in replacement for discrete base-resistor transistor pairs in logic-level interface circuits-particularly where board area, assembly cost, and thermal performance at 250 mW Ptot are critical selection criteria.
Technical Context
This RET integrates a PNP bipolar transistor with two monolithically embedded silicon resistors: R1 (input bias) and R2 (base-emitter feedback), forming a fixed-current gain configuration optimized for saturated switching. Its internal topology eliminates external base resistors while maintaining predictable VI(on)/VI(off) thresholds across temperature.
The device operates with a maximum junction temperature of 150 °C and exhibits typical fT = 180 MHz, supporting fast digital transitions. Its ultra-thin 0.37 mm package height and FR4-compatible thermal resistance (Rth(j-a) = 500 K/W) enable use in thermally dense portable PCB layouts without derating penalties below 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Withstands reverse collector-emitter voltage up to 50 V in open-base configuration, suitable for 3.3 V/5 V logic-driven loads with margin. |
| IO | −100 mA - Continuous DC output current capability enables direct driving of LEDs, small relays, or logic inputs without external current amplification. |
| R1 | 4.7 kΩ (typ) - Input bias resistor sets base current for predictable turn-on behavior with standard CMOS/TTL logic high levels. |
| R2/R1 ratio | 10 (typ) - Fixed feedback ratio ensures stable saturation and prevents unintended conduction under leakage or noise conditions. |
| VCE(sat) | −100 mV (max at IC = −5 mA, IB = −0.25 mA) - Ultra-low saturation voltage minimizes power loss and self-heating in battery-powered applications. |
| fT | 180 MHz (typ) - Transition frequency supports clean switching edges in digital control signals up to ~10–20 MHz clock domains. |
| Ptot | 250 mW (at Tamb ≤ 25 °C) - Total power dissipation limit defines safe operating area on standard FR4 PCBs without heatsinking. |
Pinout & Package
DFN1006B-3 (SOT883B) is a leadless, ultra-small surface-mount plastic package measuring 1.0 × 0.6 × 0.37 mm, optimized for high-density mobile and automotive PCBs. Its three solder lands support automated reflow assembly with minimal footprint and low thermal resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connects to logic signal source; internal R1 routes current into transistor base for controlled turn-on. |
| 2 | GND (emitter) | Common emitter reference node; tied to system ground plane for stable bias and low-inductance return path. |
| 3 | Output (collector) | Switched high-side output node; sinks current from load connected between VCC and pin 3 when active. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Monolithic R1 (4.7 kΩ) + R2 (47 kΩ) eliminates two external resistors, reducing BOM count and layout area by ≥30% vs discrete solutions. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD (HBM >2 kV), enabling use in infotainment and body control modules. |
| Ultra-low profile | 0.37 mm max height allows placement under connectors or beneath shields in slim handheld devices and wearables. |
| Simplified drive interface | VI(on) = −0.9 V (typ) and VI(off) = −0.55 V (typ) ensure robust logic-level compatibility with 1.8 V/3.3 V microcontrollers without level-shifting. |
| Thermal efficiency | Rth(j-a) = 500 K/W enables full 250 mW power handling on standard FR4 without thermal vias or copper pours in most consumer designs. |

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 |
|---|---|---|---|
| PDTC143ZMB | NPN complement with identical R1/R2 values and package; requires inverted logic drive and low-side load configuration. | Used where load connects to VCC and switch sinks current to ground-common in microcontroller I/O expansion. | Select when circuit topology favors NPN low-side switching and existing layout accommodates polarity inversion. |
| EMX13T2R | PNP RET in SOT-323 package (1.7 × 1.3 × 0.9 mm); higher Ptot = 300 mW but 2.4× larger footprint and no AEC-Q101 rating. | Suitable for industrial control boards where space is less constrained and automotive qualification is not required. | Choose only if thermal headroom >250 mW is needed and AEC-Q101 compliance is unnecessary. |
Compared with PDTC143ZMB and EMX13T2R, PDTA143ZMB uniquely combines AEC-Q101 qualification, ultra-miniature DFN1006B-3 packaging, and guaranteed −100 mV VCE(sat)-making it the optimal choice for space- and reliability-critical automotive and mobile applications requiring PNP high-side switching.

FAQ
What is the maximum allowable ambient temperature for continuous operation at full rated current?
The PDTA143ZMB supports continuous −100 mA output current up to 25 °C ambient temperature. Above that, power derating applies per Figure 2: at 75 °C ambient, maximum continuous current drops to approximately −60 mA to maintain junction temperature ≤150 °C on standard FR4 PCBs.
Can this device be used with 1.8 V logic controllers?
Yes. VI(on) is −0.9 V (typ) and VI(off) is −0.55 V (typ), meaning a 1.8 V GPIO high output (≥1.8 V) fully exceeds the turn-on threshold, while a 0 V GPIO low output ensures reliable cutoff. No level shifter is required for 1.8 V/3.3 V systems.
Is thermal vias recommended for the DFN1006B-3 package?
No. The DFN1006B-3 footprint is too small (0.6 mm wide) to accommodate effective thermal vias. Instead, Nexperia specifies performance using standard FR4 with single-sided 1 oz copper and tin plating-achieving Rth(j-a) = 500 K/W without additional thermal enhancements.
How does the R2/R1 ratio affect switching behavior?
An R2/R1 ratio of 10 provides strong negative feedback to stabilize the base-emitter junction, ensuring deep saturation at low IB/IC ratios and suppressing leakage-induced false turn-on. This improves noise immunity and reduces sensitivity to temperature drift in battery-operated systems.
