Product details
Overview
PDTA124ET,215 from Nexperia is a PNP resistor-equipped transistor (RET) in SOT23 package, designed for digital switching applications with built-in bias resistors R1 = 22 kΩ and R2 = 22 kΩ, −50 V VCEO, −100 mA IO, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PDTA124ET,215 datasheet, PDTA124ET,215 pinout, PDTA124ET,215 application, or PDTA124ET,215 equivalent, this device serves as a space- and cost-optimized replacement for BC847/BC857-based digital interface circuits requiring simplified biasing, reduced component count, and robust thermal performance in compact PCB layouts.
Technical Context
This PNP RET integrates two precision bias resistors (R1 = 22 kΩ, R2/R1 = 1.0 ±0.2) directly into the SOT23 package, eliminating external base resistors and enabling direct logic-level drive. Its −1.7 V typical VI(on) at −5 mA IC ensures reliable turn-on with standard CMOS/TTL outputs.
The device operates with −150 mV typical VCE(sat) at −10 mA IC/−0.5 mA IB, supports −100 nA ICEO leakage at −30 V VCE, and delivers 180 MHz fT - confirming suitability for high-speed digital switching up to ~10 MHz edge rates in automotive body control modules and industrial I/O interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum safe collector-emitter voltage under open-base conditions; enables use in 24 V automotive supply rails with margin. |
| IO | −100 mA - Continuous output current capability; sufficient for driving LEDs, small relays, or logic inputs without external buffering. |
| R1 | 22 kΩ (15.4–28.6 kΩ) - Integrated input bias resistor; eliminates discrete resistor placement and reduces BOM count by one component. |
| VCE(sat) | −150 mV max at −10 mA IC/−0.5 mA IB - Low saturation voltage minimizes power loss and heat generation during on-state operation. |
| fT | 180 MHz - Transition frequency confirms fast switching response; supports clean digital edges in microcontroller GPIO interfacing. |
| AEC-Q101 | Qualified - Meets automotive-grade stress test requirements for temperature cycling, HTRB, and ESD; suitable for under-hood and cabin ECUs. |
| Ptot | 250 mW at Tamb ≤ 25 °C - Thermal rating enables stable operation in SOT23 footprint without heatsinking in ambient temperatures up to 85 °C. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package with 3 leads; 1.9 mm × 1.1 mm × 1.2 mm body dimensions; reflow soldering compatible; standard footprint per Fig 18.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level input signal; no external base resistor required. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; provides return path for load current and bias network. |
| 3 | Output (collector) | Switched output node; sinks current from load (e.g., LED anode, MCU input pull-down) when active. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 + R2 bias network | 22 kΩ input resistor and 22 kΩ base-emitter resistor eliminate two external components and reduce PCB area by ≥2 mm². |
| Low VI(on) | −1.7 V typical at −5 mA IC - Ensures full turn-on with 3.3 V or 5 V logic outputs without level-shifting. |
| High DC current gain | hFE ≥ 60 at −5 mA IC/−5 V VCE - Provides stable switching margin across temperature and process variation. |
| Ultra-low leakage | ICEO ≤ −100 nA at −30 V VCE - Prevents false triggering in high-impedance or battery-powered standby circuits. |
| Leadless-compatible footprint | SOT23 outline matches JEDEC TO-236AB; supports automated pick-and-place and reflow with industry-standard stencil design. |
Applications
| Automotive Body Control Unit (BCU) | Industrial PLC Digital Input Module |
|---|---|
|

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 |
|---|---|---|---|
| PDTC124ET,215 | NPN complement; same R1/R2 values, SOT23 package, identical thermal specs and AEC-Q101 rating. | Requires inverted logic drive; used where active-high control or sourcing (vs. sinking) is needed. | Select when interfacing with open-collector/drain outputs or when load must be connected to VCC. |
| NSV124EHT1G | PNP RET with R1 = 22 kΩ, R2 = 22 kΩ, but rated only to −40 V VCEO and not AEC-Q101 qualified. | Limited to consumer-grade 12 V systems; unsuitable for automotive or industrial environments with voltage transients. | Choose only for cost-sensitive non-automotive applications where −40 V rating suffices and qualification is not required. |
Compared with PDTC124ET,215, PDTA124ET,215 provides native active-low switching for sink-driven loads, while NSV124EHT1G offers lower cost at the expense of voltage margin and automotive qualification - making PDTA124ET,215 the optimal choice for safety-critical 24 V automotive and industrial digital I/O.

FAQ
What is the maximum operating temperature for PDTA124ET,215?
The junction temperature (Tj) limit is 150 °C, and the ambient temperature range is −65 °C to +150 °C. Derating begins above 25 °C ambient, with total power dissipation dropping linearly to zero at 150 °C per the 500 K/W Rth(j-a) curve in Figure 4. Full-rated 250 mW operation is guaranteed only at Tamb ≤ 25 °C.
Can PDTA124ET,215 replace BC857 in existing designs?
Yes - PDTA124ET,215 is explicitly positioned as a cost-saving alternative to BC857 in digital applications. It matches BC857's PNP polarity and SOT23 footprint, adds integrated 22 kΩ bias resistors, and improves reliability via AEC-Q101 qualification. No layout change is needed beyond removing the two external base resistors.
Is wave soldering supported for PDTA124ET,215?
No - the datasheet explicitly states "Reflow soldering is the only recommended soldering method." Figure 19 shows a wave soldering footprint for reference only; Nexperia does not guarantee performance or reliability if wave soldering is used due to thermal stress risks on the internal resistor elements and die attach.
What is the meaning of the marking code *05 on PDTA124ET,215?
The marking code *05 consists of a placeholder (*) for the manufacturing site code followed by "05", which identifies the PDTA124E series. This matches Table 5 in the datasheet and is laser-marked on the top surface of the SOT23 package for traceability and series identification.
