Product details
Overview
PDTA143XM from Nexperia is a PNP resistor-equipped transistor (RET) in a leadless ultra-small SOT883 (SC-101) package, designed for digital switching applications with built-in bias resistors R1 = 4.7 kΩ and R2/R1 = 2.1, −50 V VCEO, −100 mA IO, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PDTA143XM datasheet, PDTA143XM pinout, PDTA143XM application, or PDTA143XM equivalent, this device serves as a space-optimized, drop-in-ready digital switch for IC input control and low-power load switching where board area, component count, and automotive-grade reliability are critical.
Technical Context
This PNP RET integrates two precision bias resistors (R1 = 4.7 kΩ, R2/R1 = 2.1) to eliminate external base resistors, enabling direct logic-level drive from microcontrollers or gate drivers. Its −100 mA output current and −100 mV VCE(sat) at IC = −10 mA support robust saturation in low-voltage digital interfaces.
The SOT883 package delivers 250 mW power dissipation and 500 K/W junction-to-ambient thermal resistance, optimized for reflow-only assembly on FR4 PCBs with 70 μm copper traces-making it suitable for high-density automotive body electronics and industrial sensor nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Ensures safe operation in 24 V automotive supply rails with transient margin. |
| IO | −100 mA - Supports driving moderate loads like LED indicators or small relays directly. |
| R1 | 4.7 kΩ - Sets precise base current for predictable turn-on without external components. |
| R2/R1 | 2.1 - Provides stable internal feedback ratio for reliable cutoff and noise immunity. |
| VCE(sat) | −100 mV @ IC = −10 mA - Minimizes conduction loss and self-heating in always-on digital control paths. |
| fT | 180 MHz - Enables fast switching (>10 MHz) in pulse-width modulated or timing-critical digital circuits. |
| Ptot | 250 mW @ Tamb ≤ 25 °C - Matches thermal capability of ultra-compact SOT883 footprint for dense layouts. |
Pinout & Package
SOT883 (SC-101) is a leadless ultra-small plastic package measuring 1.0 × 0.6 × 0.5 mm, with three solder lands optimized for reflow-only assembly on FR4 PCBs using 70 μm copper strip lines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-high signal to activate PNP switch. |
| 2 | GND (emitter) | Common reference node tied to system ground; carries full load current return path. |
| 3 | Output (collector) | Switched output node; sinks current from load connected to positive rail (e.g., 3.3 V/5 V/12 V). |
Key Features
| Feature | Design Value |
|---|---|
| Built-in bias resistors | Eliminates two external resistors, reducing BOM count and layout area by ≥2 mm². |
| AEC-Q101 qualified | Validated for automotive temperature range (−40 °C to +150 °C) and mechanical stress requirements. |
| Ultra-small SOT883 footprint | 1.0 × 0.6 mm body enables placement in tight spaces such as camera modules or ECU edge connectors. |
| Low VCE(sat) | −100 mV ensures <10 mW conduction loss at 100 mA, minimizing thermal rise in sealed enclosures. |
| Reflow-only assembly | Compatible with standard lead-free reflow profiles-no wave soldering required, simplifying manufacturing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP digital switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTC143XM | NPN complement with identical R1/R2 values, SOT883 package, and matching thermal specs. | Requires inverted logic drive and low-side switching topology instead of high-side PNP configuration. | Select when circuit uses NPN-compatible control signals or requires sink-based load management. |
| BC807-40,215 | Standard PNP BJT without built-in resistors; requires external RB and RBE; larger SOT23 package. | Higher board area usage and additional pick-and-place steps; lacks AEC-Q101 qualification. | Choose only if legacy design reuse or higher VCEO (−45 V) is prioritized over miniaturization and qualification. |
Compared with PDTC143XM, PDTA143XM enables high-side sourcing without logic inversion, while versus BC807-40 it reduces layout area by 65% and eliminates two passives-critical for next-gen automotive and portable medical devices requiring validated reliability and minimal footprint.

FAQ
What is the maximum operating temperature for PDTA143XM?
The PDTA143XM has a maximum junction temperature (Tj) of 150 °C and an ambient operating range of −65 °C to +150 °C. Its thermal resistance (Rth(j-a)) is 500 K/W on FR4 with 70 μm copper, allowing full 100 mA output current up to +85 °C ambient before derating begins-verified per IEC 60134 limiting values.
Can PDTA143XM replace BC847/857 series transistors directly?
Yes-PDTA143XM serves as a cost-saving, space-optimized alternative to BC847/857 in digital switching roles, but requires no external base resistors and operates as a PNP RET rather than a bare BJT. It matches key parameters including VCEO (−50 V), IC (−100 mA), and hFE (≥50), though logic polarity differs due to integrated biasing.
Is reflow soldering mandatory for PDTA143XM?
Yes-Nexperia specifies reflow soldering as the only recommended method for PDTA143XM due to its SOT883 leadless construction. Wave soldering is not supported; the device's thermal profile and solder land geometry (0.3 mm × 0.22 mm pads, 0.7 mm pitch) are validated exclusively for lead-free reflow per J-STD-020.
What does the marking 'DN' indicate on PDTA143XM units?
The top-side marking 'DN' identifies the PDTA143XM variant per Nexperia's standardized coding system (Table 5). It corresponds uniquely to the SOT883 package, distinguishes it from other members of the PDTA143X series (e.g., '35' for SOT416), and is laser-etched for automated optical inspection compatibility in high-volume SMT lines.
