Product details
Overview
PDTA114ET-QR from Nexperia is a PNP resistor-equipped transistor (RET) in SOT23 package, rated for −50 V VCEO, −100 mA output current, with integrated R1 = 10 kΩ and R2 = 10 kΩ bias resistors; used as a digital switch for IC input control and load switching in automotive ECUs.
For engineers reviewing the PDTA114ET-QR datasheet, PDTA114ET-QR pinout, PDTA114ET-QR application, or PDTA114ET-QR equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal derating behavior, and validated automotive-grade switching performance - all confirmed from Nexperia's official product data sheet dated 19 February 2024.
Technical Context
This PNP RET integrates two precision bias resistors (R1 = 10 kΩ, R2/R1 = 1.0 typ.) to eliminate external base resistors, enabling direct logic-level drive from 3.3 V or 5 V microcontrollers. Its −50 V VCEO and −100 mA IO support robust switching in 12 V automotive subsystems.
The device operates across −65 °C to +150 °C ambient, with junction temperature limited to 150 °C and thermal resistance Rth(j-a) = 500 K/W on FR4 PCB. It exhibits VCE(sat) ≤ −150 mV at IC = −10 mA / IB = −0.5 mA, ensuring low conduction loss in digital on/off control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum collector-emitter voltage before breakdown; supports 12 V automotive rail with margin. |
| IO | −100 mA: Continuous output current capability; sufficient for driving LEDs, relays, or logic inputs. |
| R1 | 10 kΩ (7–13 kΩ): Input bias resistor enabling direct TTL/CMOS interface without external components. |
| VCE(sat) | ≤ −150 mV at IC = −10 mA: Low saturation voltage minimizes power dissipation during on-state operation. |
| VI(on) | −2.5 to −1.8 V at IC = −10 mA: Confirmed turn-on threshold compatible with standard 3.3 V logic high. |
| hFE | ≥30 at VCE = −5 V, IC = −5 mA: Guaranteed DC current gain ensures reliable switching under worst-case conditions. |
| AEC-Q101 | Qualified: Meets stress test requirements for discrete semiconductors in automotive applications. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body; optimized for automated placement and reflow soldering per IPC-7351B footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level drive signal directly from MCU GPIO or buffer. |
| 2 | Ground (emitter) | Common emitter node; ties to system ground plane; serves as reference for input and output paths. |
| 3 | Output (collector) | Switched high-side output node; sinks current from load connected between VCC and pin 3. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1/R2 bias network | Eliminates 2 external resistors; reduces BOM count and layout area in space-constrained modules. |
| −100 mA continuous output | Supports direct driving of small solenoids, indicator LEDs, or optocoupler inputs without amplification. |
| AEC-Q101 qualification | Validated for automotive use including engine control, body electronics, and ADAS sensor interfaces. |
| VI(off) ≥ −1.1 V | Ensures reliable cutoff with 3.3 V logic low (0.4 V), preventing unintended turn-on in noisy environments. |
| Low Rth(j-a) = 500 K/W | Enables 250 mW total power dissipation at Tamb = 25 °C; supports operation up to 100 °C ambient without derating. |
Applications
| Automotive Body Control Module | Industrial PLC Digital Output |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP digital switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTC114ET-Q | NPN complement; same R1/R2 values and AEC-Q101 rating but opposite polarity. | Requires low-side switching topology; incompatible with high-side load configurations. | Select when driving loads referenced to VCC (e.g., N-channel MOSFET gate) rather than ground-referenced loads. |
| BC807-40-Q | Standard PNP BJT without integrated resistors; requires external RB and RBE; hFE = 250–630. | Higher gain but increased BOM count and sensitivity to layout parasitics; not pre-biased. | Choose only if precise gain control or higher current (>100 mA) is required and board space permits extra passives. |
Compared with PDTC114ET-Q, PDTA114ET-QR provides high-side switching capability with guaranteed biasing; versus BC807-40-Q, it trades off gain flexibility for reduced assembly cost and improved ESD robustness via monolithic integration.

FAQ
Is PDTA114ET-QR pin-compatible with BC847-Q series transistors?
No. PDTA114ET-QR uses SOT23 pinning (1=Input, 2=GND, 3=Output), while BC847-Q variants follow standard BJT pinout (1=E, 2=B, 3=C). Direct replacement requires PCB redesign due to reversed terminal assignment and integrated biasing.
What is the maximum allowable input voltage at Pin 1?
The absolute maximum input voltage at Pin 1 is −40 V, per VI rating in Table 5. However, functional operation is specified for −2.5 V to −1.8 V (VI(on)) and −1.1 V to −0.8 V (VI(off)) under typical conditions; sustained input above −10 V risks exceeding R1 power rating.
Does PDTA114ET-QR support PWM switching at frequencies above 10 kHz?
Yes. With fT = 180 MHz (typ.) for the internal transistor and Cc = 3 pF, it supports clean switching up to at least 100 kHz in low-inductance layouts; VCE(sat) remains stable across temperature, enabling reliable PWM dimming and motor enable control.
How does the R2/R1 ratio affect switching behavior?
The R2/R1 ratio of 0.8–1.2 (typ. 1.0) sets base-emitter shunt resistance, stabilizing turn-off by providing a defined discharge path. This prevents latch-up in noisy environments and ensures consistent VI(off) ≤ −0.8 V, critical for fail-safe operation in automotive systems.
