Product details
Overview
PDTA123JT,215 from Nexperia is a PNP resistor-equipped transistor (RET) in SOT23 package, designed for digital switching applications with built-in bias resistors R1 = 2.2 kΩ and R2/R1 ratio = 21. It delivers −100 mA output current, −50 V collector-emitter voltage rating, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PDTA123JT,215 datasheet, PDTA123JT,215 pinout, PDTA123JT,215 application, or PDTA123JT,215 equivalent, key selection criteria include its integrated base resistors, guaranteed VCE(sat) ≤ −100 mV at IC = −5 mA/IB = −0.25 mA, off-state input voltage VI(off) = −0.6 V, and thermal resistance Rth(j-a) = 500 K/W on FR4 PCB.
Technical Context
This PNP RET integrates two precision silicon resistors (R1 = 2.2 kΩ, R2 = 47 kΩ) directly into the die to eliminate external bias components. Its internal transistor exhibits hFE ≥ 100 at IC = −10 mA and VCE = −5 V, enabling reliable saturation in low-voltage logic-level control circuits.
The device operates across −65 °C to +150 °C ambient temperature, supports reflow soldering only, and maintains stable DC current gain across temperature extremes (−40 °C to +100 °C), making it suitable for under-hood automotive modules and industrial PLC I/O stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum safe collector-emitter voltage with open base; enables use in 24 V automotive supply rails with margin. |
| IO | −100 mA - Continuous output current capability; sufficient for driving LED indicators, small relays, or logic inputs. |
| R1 | 2.2 kΩ ±30% - Integrated input bias resistor; eliminates need for external pull-up/pull-down, reducing BOM count. |
| R2/R1 | 21 - Fixed internal resistor ratio; ensures predictable base current division and consistent turn-on behavior. |
| VCE(sat) | ≤ −100 mV at IC = −5 mA/IB = −0.25 mA - Low saturation voltage minimizes power loss and heat generation in switching mode. |
| VI(on) | −0.75 V typical - On-state input voltage threshold; compatible with 3.3 V and 5 V CMOS/TTL logic outputs. |
| AEC-Q101 | Qualified - Meets automotive-grade stress test requirements for discrete semiconductors; validated for under-hood use. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package with 3 leads; standard footprint optimized for reflow soldering on FR4 PCBs. Thermal resistance Rth(j-a) = 500 K/W under specified mounting conditions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1 and R2 network; accepts logic-level control signal without external biasing. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; serves as common reference for input and output paths. |
| 3 | Output (collector) | Switched high-side load connection point; sinks current when device is active (PNP configuration). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | R1 = 2.2 kΩ, R2 = 47 kΩ - Eliminates two external resistors, reducing PCB area and assembly cost. |

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 |
|---|---|---|---|
| PDTC123JT | NPN complement with identical R1/R2 values and SOT23 package; requires inverted logic drive. | Used where low-side switching or active-low control is preferred in the same board layout. | Select when circuit topology demands NPN configuration or existing design uses complementary pairs. |
| BC857B,215 | Standard PNP BJT without integrated resistors; requires external base bias network. | Offers higher hFE (200–450) but increases component count and layout area. | Choose when precise gain control or higher current gain is required, and space for two resistors is available. |
Compared with PDTC123JT, PDTA123JT,215 provides native high-side switching with logic-compatible input, while BC857B,215 offers greater DC gain flexibility at the cost of added passive components and design effort.

FAQ
What is the maximum continuous collector current for PDTA123JT,215?
The maximum continuous output current is −100 mA, verified under standard FR4 PCB mounting conditions with single-sided copper. This rating applies at Tamb ≤ 25 °C; derating is required above that temperature per the published power derating curve (500 K/W thermal resistance).
Can PDTA123JT,215 be used in place of a standard PNP transistor like BC857?
Yes, but only in digital switching roles where its integrated R1/R2 network matches the required biasing. Unlike BC857, it cannot be used in linear amplifier configurations due to fixed internal resistors. It replaces BC857-based digital switches with reduced component count and improved consistency.
Is wave soldering supported for PDTA123JT,215?
No - reflow soldering is the only recommended method per Nexperia's data sheet. Wave soldering is not qualified and may damage the device or compromise solder joint integrity. The SOT23 footprint is optimized for reflow profiles defined in JEDEC J-STD-020.
What does the marking "*23" indicate on PDTA123JT,215 devices?
The marking "*23" is the top-side laser code per Table 5, where "*" is a placeholder for the manufacturing site code and "23" identifies the PDTA123JT type. This marking appears on the package top surface and is used for traceability and lot identification during inspection and failure analysis.
