Product details
Overview
PDTB114ETVL from Nexperia is a PNP resistor-equipped transistor (RET) in SOT23 (TO-236AB) package, designed for digital switching applications with −50 V VCEO, −500 mA IO, 10 kΩ R1, 10 kΩ R2, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PDTB114ETVL datasheet, PDTB114ETVL pinout, PDTB114ETVL application, or PDTB114ETVL equivalent, this device serves as a simplified, high-temperature (up to 175 °C), bias-resistor-integrated alternative to discrete BJT + base resistors in logic-level load switching, IO interface protection, and automotive body control modules.
Technical Context
This PNP RET integrates two precision bias resistors (R1 = 10 kΩ, R2 = 10 kΩ, ratio = 1.0 ±10 %) directly into the package, eliminating external base resistors and reducing PCB footprint. It operates as a single-pole digital switch with guaranteed turn-on at VI(on) ≤ −3.0 V and turn-off at VI(off) ≥ −1.5 V under specified conditions.
The built-in transistor delivers hFE ≥ 70 at IC = −50 mA and VCE = −5 V, with VCE(sat) ≤ −100 mV at IC = −50 mA / IB = −2.5 mA, enabling low-loss switching in 12 V/24 V automotive systems and industrial IO drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum safe collector-emitter voltage before breakdown; supports 24 V automotive rail with margin. |
| IO | −500 mA - Continuous output current capability; sufficient for driving relays, LEDs, and small solenoids. |
| R1 | 10 kΩ ±30 % - Input bias resistor value; sets base current for predictable turn-on behavior with TTL/CMOS logic. |
| R2 | 10 kΩ ±30 % - Base-emitter feedback resistor; stabilizes operating point and improves noise immunity. |
| VCE(sat) | ≤ −100 mV at IC = −50 mA - Low saturation voltage minimizes power loss and self-heating during conduction. |
| Tj(max) | 175 °C - Junction temperature rating enables operation in under-hood automotive environments without derating. |
| AEC-Q101 | Qualified - Meets stress-test requirements for discrete semiconductors in automotive applications. |
Pinout & Package
Package: SOT23 (TO-236AB), surface-mount plastic package with 3 leads, 1.9 mm × 1.1 mm × 0.9 mm body, standard reflow-compatible footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level control signal to activate the PNP switch. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; provides return path for load current. |
| 3 | Output (collector) | Switched high-side output node; connects to load (e.g., relay coil anode or LED cathode). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Matched R1/R2 = 10 kΩ/10 kΩ with ±10 % ratio tolerance eliminates external components and layout sensitivity. |
| Automotive-grade reliability | AEC-Q101 qualification ensures robustness against thermal cycling, humidity, and mechanical stress in vehicle ECUs. |
| High-temperature operation | Rated up to Tamb = +175 °C ambient and Tj = +175 °C junction, supporting under-dash and engine-bay placements. |
| Digital input compatibility | VI(on) ≤ −2.2 V (typ) and VI(off) ≥ −1.5 V (max) ensure reliable switching with 3.3 V/5 V CMOS and open-collector drivers. |
| Low saturation loss | VCE(sat) ≤ −100 mV at rated current reduces power dissipation to < 5 mW, easing thermal design. |
Applications

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 |
|---|---|---|---|
| PDTB143ET | R1 = R2 = 4.7 kΩ; lower input threshold (VI(on) ≤ −2.2 V typ); hFE ≥ 60 | Better suited for 3.3 V logic drive; higher base current draw may increase MCU loading | Select when interfacing with low-voltage microcontrollers and faster switching is required. |
| BC807-40 | Discrete PNP BJT without built-in resistors; requires external RB and RBE; VCEO = −45 V; IC = −500 mA | Higher design flexibility but increases component count, layout area, and calibration effort | Choose only if precise bias tuning or non-standard resistor ratios are needed. |
Compared with PDTB143ET, PDTB114ET offers higher input impedance and reduced MCU drive burden due to larger R1/R2, while BC807-40 demands additional passives and lacks AEC-Q101 validation, making PDTB114ET preferable for automotive and space-constrained industrial designs.

FAQ
What is the maximum allowable input voltage (VI) for PDTB114ETVL?
The absolute maximum input voltage is −50 V (negative-going) and +10 V (positive-going), per Table 6. Exceeding these values risks permanent damage to the internal bias resistors or transistor junction. For reliable operation, keep VI within −30 V to +7 V during normal switching, with typical on/off thresholds at −2.2 V and −1.0 V respectively.
Can PDTB114ETVL replace BC807-40 in existing designs without layout changes?
No - PDTB114ETVL uses SOT23 pinout (1=Input, 2=Emitter/GND, 3=Collector), whereas BC807-40 in SOT23 has 1=Emitter, 2=Base, 3=Collector. Direct replacement requires PCB redesign to accommodate different pin functions and eliminate external base resistors. Functional equivalence exists, but not pin-for-pin compatibility.
How does the 10 kΩ/10 kΩ resistor ratio affect switching performance?
The matched R1/R2 ratio of 1.0 ±10 % ensures stable DC biasing and consistent turn-on characteristics across temperature and process variation. It yields predictable base current (IB ≈ (VI − VBE)/R1) and prevents unintended conduction due to leakage, especially critical in high-temperature automotive environments.
Is thermal derating required above 25 °C ambient?
Yes - total power dissipation must be derated linearly above 25 °C. With Rth(j-a) = 470 K/W (single-layer PCB), Ptot drops from 320 mW at 25 °C to 0 mW at 175 °C. At 100 °C ambient, max allowed power is ~170 mW; actual dissipation (e.g., 500 mA × 100 mV = 50 mW) remains well within safe limits up to 150 °C ambient.
