Product details
Overview
PDTA124EU,135 from Nexperia is a PNP resistor-equipped transistor (RET) in SOT323 (SC-70) surface-mount 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 PDTA124EU,135 datasheet, PDTA124EU,135 pinout, PDTA124EU,135 application, or PDTA124EU,135 equivalent, key selection criteria include guaranteed input/output voltage thresholds (VI(on) = −1.7 V typ, VI(off) = −1.1 V typ), thermal resistance (Rth(j-a) = 625 K/W), and compatibility with reflow-only soldering on FR4 PCBs.
Technical Context
This PNP RET integrates two precision bias resistors (R1 = 22 kΩ ±30%, R2/R1 = 1.0 ±20%) directly into a monolithic silicon die, eliminating external base resistors and enabling direct logic-level drive from microcontrollers or gate outputs. Its internal structure ensures predictable turn-on/turn-off behavior without external component tuning.
The device operates as a single-polarity digital switch with defined saturation characteristics: VCE(sat) ≤ −150 mV at IC = −10 mA / IB = −0.5 mA, and hFE ≥ 60 at IC = −5 mA, supporting reliable low-power load control in space-constrained designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum allowable collector-emitter voltage before breakdown; 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. |
| R1 | 22 kΩ ±30% - Integrated input bias resistor; eliminates need for external pull-up/pull-down, reducing BOM count. |
| VI(on) | −1.7 V (typ) - Minimum input voltage to guarantee full conduction; compatible with 3.3 V and 5 V CMOS/TTL logic families. |
| VI(off) | −0.8 V (min) - Maximum input voltage to ensure cutoff; provides noise immunity against spurious low-level signals. |
| Rth(j-a) | 625 K/W - Junction-to-ambient thermal resistance on standard FR4 PCB; defines maximum power dissipation (200 mW) at Tamb = 25 °C. |
| AEC-Q101 | Qualified - Certified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22 standards. |
Pinout & Package
SOT323 (SC-70) plastic surface-mounted package, 3-lead, body dimensions 2.2 mm × 1.35 mm × 1.15 mm, optimized for high-density PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1 and R2; accepts logic-level control signal; no external base connection required. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; serves as common reference for input and output paths. |
| 3 | Output (collector) | Switched high-side output node; sinks current when active; connects to load between VCC and pin 3. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | R1 = 22 kΩ and R2 = 22 kΩ on-die resistors eliminate two external components and associated layout area. |
| Automotive qualification | AEC-Q101 certified for under-hood and infotainment applications requiring extended temperature operation (−65 °C to +150 °C). |
| Reflow-only soldering | Validated for lead-free reflow profiles only; avoids mechanical stress and intermetallic degradation from wave soldering. |
| Digital switching optimization | VI(on)/VI(off) thresholds and hFE ≥ 60 ensure clean logic-level interfacing without external level-shifting circuitry. |
| Space-efficient packaging | SOT323 footprint (2.2 × 1.35 mm) reduces board area by >40% vs. legacy SOT23 while maintaining identical 3-pin topology. |
Applications
| Automotive Body Control Module | Industrial PLC Input Stage |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP digital switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTC124EU,135 | NPN complement with identical R1/R2 values, package, and ratings; requires inverted logic drive. | Used where load is connected to ground and source-switching is preferred over sink-switching. | Select when circuit topology mandates NPN configuration or existing design uses complementary pairs. |
| BC807-40,215 | Standard PNP BJT without integrated resistors; requires external base bias network; higher hFE (250–630) but no guaranteed VI(on)/VI(off). | Suitable for linear amplification or variable-current control, not logic-driven switching. | Choose only if precise gain control or analog operation is needed; not drop-in for RET-based digital logic interfaces. |
Compared with PDTC124EU,135, this part offers native PNP sink-switching without logic inversion, while BC807-40 demands additional passives and lacks guaranteed switching thresholds-making PDTA124EU,135 optimal for deterministic digital control in compact, high-reliability systems.

FAQ
Is PDTA124EU,135 compatible with lead-free reflow soldering processes?
Yes. The device is qualified exclusively for lead-free reflow soldering per J-STD-020; wave soldering is not recommended due to thermal stress risks. The SOT323 package supports peak temperatures up to 260 °C for ≤30 seconds, matching standard IPC Class 3 profiles.
What is the maximum ambient temperature for continuous operation at full rated current?
At IO = −100 mA, the device dissipates up to 15 mW in saturation (VCE(sat) ≈ −150 mV). With Rth(j-a) = 625 K/W, junction temperature rise is ~9.4 °C, allowing continuous operation up to +140.6 °C ambient before reaching Tj(max) = 150 °C.
Can PDTA124EU,135 drive a 10 mA LED directly from a 3.3 V GPIO?
Yes. With VI(on) ≤ −1.7 V and IO = −100 mA rating, it fully saturates when driven by a 3.3 V logic high (via pull-up to 3.3 V on pin 1), sinking up to 10 mA through an LED anode-connected to VCC and cathode to pin 3.
How does the R2/R1 ratio affect switching behavior?
The R2/R1 ratio of 1.0 ±20% sets the internal base current division, ensuring stable hFE-independent switching with minimal sensitivity to transistor gain variation. This guarantees consistent VI(on) and VI(off) across process and temperature without external trimming.
