Product details
Overview
PDTA123JU,115 from Nexperia is a PNP resistor-equipped transistor (RET) in SOT323 (SC-70) package, integrating R1 = 2.2 kΩ and R2/R1 = 21 ratio bias resistors. It delivers −100 mA output current, −50 V VCEO, and −100 mV VCEsat at IC = −5 mA/IB = −0.25 mA, serving as a compact digital switch for automotive and industrial control inputs.
For engineers reviewing the PDTA123JU,115 datasheet, PDTA123JU,115 pinout, PDTA123JU,115 application, or PDTA123JU,115 equivalent, key selection criteria include built-in bias resistor matching (R1 = 2.2 kΩ, R2/R1 = 21), AEC-Q101 qualification, −100 mA switching capability, and SOT323 footprint compatibility with high-density PCB layouts.
Technical Context
This PNP RET integrates two precision on-chip resistors (R1 = 2.2 kΩ, R2 = 47 kΩ) to replace external base bias networks, enabling direct logic-level drive without discrete resistors. Its −50 V VCEO and −100 mA IO rating support robust switching in 5 V–24 V digital interface rails.
The device features −100 mV VCEsat at IC = −5 mA/IB = −0.25 mA and VI(on) = −0.75 V typical, ensuring low-loss saturation and reliable turn-on with standard CMOS/TTL outputs. AEC-Q101 qualification confirms suitability for automotive body electronics and industrial I/O modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum collector-emitter voltage before breakdown; supports 24 V automotive supply rails with margin. |
| IO | −100 mA - Continuous output current capability; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 | 2.2 kΩ - Integrated input bias resistor; eliminates need for external pull-up/pull-down in digital switch applications. |
| R2/R1 | 21 - Fixed internal resistor ratio; sets precise base current gain for predictable saturation behavior. |
| VCEsat | −100 mV @ IC = −5 mA/IB = −0.25 mA - Low saturation voltage minimizes power loss and heat generation during on-state operation. |
| VI(on) | −0.75 V typical @ VCE = −0.3 V/IC = −5 mA - Ensures reliable turn-on with standard 3.3 V or 5 V logic outputs. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing. |
Pinout & Package
SOT323 (SC-70) plastic surface-mounted package: 3-lead, very small outline; dimensions 2.2 mm × 1.35 mm × 1.15 mm; optimized for high-density PCB assembly using reflow soldering only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1 and R2 network; accepts logic-level control signal directly from MCU GPIO or buffer output. |
| 2 | GND (emitter) | Emitter tied to system ground; provides common reference for input and output paths; not floating. |
| 3 | Output (collector) | Switched high-side load connection point; sinks current when active; compatible with open-collector logic interfaces. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | R1 = 2.2 kΩ ±30 %, R2 = 47 kΩ ±30 % - Eliminates two external resistors, reducing BOM count and layout area by ~30 %. |
| Low saturation voltage | VCEsat = −100 mV @ IC = −5 mA - Enables <1 mW conduction loss at 5 mA, critical for thermally constrained modules. |
| AEC-Q101 qualification | Stress-tested per automotive discrete semiconductor standard - Confirms reliability for under-hood and chassis-mounted applications. |
| Digital switching optimization | VI(on) = −0.75 V / VI(off) = −0.6 V - Matches TTL/CMOS logic thresholds for noise-immune, bounce-free switching without hysteresis circuitry. |
| Small-footprint packaging | SOT323 (SC-70) - 2.2 mm × 1.35 mm footprint saves >50 % board space vs. legacy SOT23 equivalents. |

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 |
|---|---|---|---|
| PDTC123JU | NPN complement; identical R1/R2 values and SOT323 package; VCEO = +50 V, IO = +100 mA. | Used where active-high logic control or sourcing (vs. sinking) is required; not interchangeable without circuit redesign. | Select PDTC123JU only when NPN topology matches system-level signal polarity and drive architecture. |
| BC807-40,215 | Standard PNP BJT without integrated resistors; requires external R1/R2; same SOT23 package but larger footprint than SOT323. | Offers higher hFE (250–630) and lower VCEsat (−150 mV) but increases BOM count and layout complexity. | Choose BC807-40,215 only when variable gain or tighter VCEsat tolerance is mandatory and board space permits external resistors. |
Compared with PDTC123JU, PDTA123JU,115 provides complementary PNP functionality with identical biasing for dual-rail designs, while BC807-40,215 trades integration for higher DC gain-making PDTA123JU,115 optimal for space-constrained, high-volume digital switching where resistor integration reduces cost and assembly risk.

FAQ
What is the maximum operating temperature for PDTA123JU,115?
The junction temperature (Tj) limit is 150 °C, and ambient operating range is −65 °C to +150 °C. Thermal resistance Rth(j-a) is 625 K/W on FR4 PCB with standard footprint, meaning at 25 °C ambient and 100 mW dissipation, junction temperature rises to ~88 °C-well within safe margin.
Can PDTA123JU,115 replace BC847/857 series directly?
Yes, as a cost-saving alternative in digital switching roles-but only where its fixed R1/R2 bias network (2.2 kΩ/47 kΩ) matches the required base drive. Unlike BC847/857, it lacks flexibility for analog amplification or variable gain, so substitution is valid only for saturated-switch applications.
Is reflow soldering mandatory for PDTA123JU,115?
Yes-reflow soldering is the only recommended method per Nexperia's data sheet. Wave soldering is not qualified for this SOT323 device due to thermal stress risks; the footprint (2.65 mm × 2.35 mm) and land pattern are optimized for lead-free reflow profiles with peak temperatures up to 260 °C.
Does PDTA123JU,115 support bidirectional signal routing?
No-it is a unidirectional PNP switch: current flows from emitter (pin 2, GND) to collector (pin 3, output) when base (pin 1, input) is pulled low. It cannot conduct in reverse or function as a pass transistor; its architecture is strictly for active-low digital control of sinking loads.
