Product details
Overview
PDTA114EU from Nexperia is a PNP resistor-equipped transistor (RET) in SOT323 (SC-70) package, designed for digital switching applications with VCEO = −50 V, IO = −100 mA, and integrated bias resistors R1 = 10 kΩ and R2 = 10 kΩ. It serves as a simplified, component-count-reducing replacement for discrete base-resistor transistor configurations in automotive and industrial control circuits.
For engineers reviewing the PDTA114EU datasheet, PDTA114EU pinout, PDTA114EU application, or PDTA114EU equivalent, this device is selected for its guaranteed input threshold behavior (VI(on) = −2.5 to −1.8 V), low saturation voltage (VCE(sat) ≤ −150 mV at IC = −10 mA), and built-in R2/R1 ratio of 1.0 ± 0.2 - critical for reliable logic-level interfacing and load switching.
Technical Context
This PNP RET integrates two precision bias resistors directly into the die assembly: R1 connects the input terminal to the base, and R2 connects base to emitter, forming a fixed-current-bias network. Its internal transistor exhibits hFE ≥ 30 at IC = −5 mA and VCE = −5 V, enabling predictable DC gain across −40 °C to +100 °C.
The device operates with defined off-state input voltage (VI(off) = −1.1 to −0.8 V) and on-state input voltage (VI(on) = −2.5 to −1.8 V), ensuring robust noise margin in 3.3 V/5 V digital systems. Its fT = 180 MHz (typ.) supports fast edge transitions, while Cc = 3 pF (typ.) minimizes capacitive loading on driving sources.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum safe collector-emitter voltage under open-base condition; defines voltage headroom for automotive 12 V and industrial 24 V rail switching. |
| IO | −100 mA - Continuous output current capability; sufficient for driving LEDs, small relays, and logic inputs without external current limiting. |
| R1 | 10 kΩ (7–13 kΩ) - Input bias resistor value; sets base current for predictable turn-on with standard CMOS/TTL logic outputs. |
| R2/R1 | 1.0 ± 0.2 - Fixed feedback-to-input resistor ratio; ensures stable bias point and consistent VI(on)/VI(off) thresholds across temperature. |
| VCE(sat) | ≤ −150 mV at IC = −10 mA, IB = −0.5 mA - Low saturation voltage reduces power loss and heat generation during active conduction. |
| hFE | ≥ 30 at VCE = −5 V, IC = −5 mA - Minimum DC current gain guarantees reliable switching margin with typical logic drive levels. |
| VI(on) | −2.5 to −1.8 V at VCE = −0.3 V, IC = −10 mA - Verified turn-on input voltage range; enables direct interface with 3.3 V microcontroller GPIOs. |
Pinout & Package
SOT323 (SC-70) plastic surface-mount package: 3-pin, 1.3 mm pitch, 2.0 mm × 1.25 mm × 0.95 mm body size, FR4 PCB mountable with standard reflow footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base node) | Connects to external logic signal; internally tied to R1 and R2 junction - accepts standard digital voltage levels without external biasing. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; provides return path for load current and establishes reference for R2 bias network. |
| 3 | Output (collector) | Switched high-side output node; sinks current from load connected between VCC and pin 3 when active. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated dual-bias resistor network | R1 = 10 kΩ, R2 = 10 kΩ - eliminates need for two external resistors, reducing BOM count and PCB area by ~2.5 mm² per instance. |
| Guaranteed VI(on)/VI(off) thresholds | VI(on) ≤ −1.8 V, VI(off) ≥ −0.8 V - ensures >0.5 V noise margin against 3.3 V logic, preventing false triggering in noisy environments. |
| Thermal derating support | Rth(j-a) = 625 K/W on FR4 - enables operation up to +85 °C ambient at full 100 mA with standard layout, verified per JEDEC JESD51-2. |
| High-speed switching capability | fT = 180 MHz (typ.), Cc = 3 pF - supports <10 ns rise/fall times in 50 Ω loads, suitable for PWM dimming and data line buffering. |

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 |
|---|---|---|---|
| PDTC114EU | NPN complement with identical R1/R2 values and package; VCEO = +50 V, IO = +100 mA. | Requires inverted logic control and low-side load placement; unsuitable for high-side switching where emitter must be grounded. | Select when driving loads referenced to ground and logic polarity allows inversion; not drop-in for PDTA114EU's high-side role. |
| BC807-40,215 | Discrete PNP transistor (no built-in resistors); hFE = 250–630, VCEO = −45 V, IC = −500 mA. | Requires external base resistor network; higher current rating but no guaranteed VI(on)/VI(off) thresholds. | Choose only when >100 mA load current or adjustable bias is required; adds design complexity and validation effort. |
Compared with PDTC114EU and BC807-40, the PDTA114EU uniquely delivers guaranteed input voltage thresholds and zero external bias components - making it optimal for space-constrained, high-volume digital switching where predictability and assembly yield are prioritized over raw current capability.

FAQ
What is the maximum continuous collector current for PDTA114EU?
The PDTA114EU is rated for −100 mA continuous output current (IO) under ambient conditions ≤25 °C with standard FR4 PCB mounting. Derating applies above 25 °C per Figure 1: at 85 °C ambient, max IO reduces to approximately −65 mA to maintain junction temperature ≤150 °C.
Can PDTA114EU be used as a direct replacement for BC847 in digital circuits?
Yes - the PDTA114EU is explicitly positioned as a cost-saving alternative to the BC847 series in digital applications. Unlike BC847, it integrates R1 and R2, eliminating two external resistors and simplifying layout, while maintaining compatible VCEO, IO, and switching speed for most logic-driven loads.
What is the function of Pin 2 (GND) in the PDTA114EU?
Pin 2 is the emitter terminal, electrically connected to system ground. It serves as the reference node for the internal R2 resistor and provides the return path for collector current. In high-side switch configuration, the load connects between VCC and Pin 3 (collector), with Pin 2 tied to GND.
Does PDTA114EU meet automotive qualification standards?
No - the PDTA114EU is not AEC-Q101 qualified. Nexperia explicitly states in its legal disclaimers that unless the data sheet expressly declares automotive qualification, the part is not suitable for automotive use. For automotive applications, consider Nexperia's AEC-Q101 qualified RETs such as PBSS4041PAS or PUMH10.
