Product details
Overview
PDTA114ET from Nexperia is a PNP resistor-equipped transistor (RET) in SOT23 package, designed for digital switching with integrated 10 kΩ input bias resistor (R1) and 10 kΩ emitter-base feedback resistor (R2), −50 V VCEO, −100 mA IO, and −150 mV VCEsat at −10 mA/−0.5 mA drive-used to control logic inputs and low-power loads in automotive and industrial modules.
For engineers reviewing the PDTA114ET datasheet, PDTA114ET pinout, PDTA114ET application, or PDTA114ET equivalent, this page delivers verified pin functions, real-world switching performance metrics, confirmed thermal derating behavior, and validated alternatives to BC847-based discrete bias networks.
Technical Context
The PDTA114ET integrates a PNP bipolar transistor with two monolithically embedded silicon resistors: R1 connects base to input terminal, R2 connects base to emitter, enabling single-resistor drive and eliminating external bias components. Its fixed R2/R1 ratio of 1.0 ±0.2 ensures stable turn-on threshold across temperature.
It operates as a saturated switch-not a linear amplifier-with guaranteed VI(on) ≤ −1.8 V and VI(off) ≥ −1.1 V at 25 °C, supporting direct interfacing with 3.3 V and 5 V CMOS/TTL logic outputs without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum collector-emitter voltage before breakdown; supports 24 V automotive supply rails with margin. |
| IO | −100 mA: Continuous output current rating; sufficient for driving LEDs, small relays, or logic gate inputs. |
| R1 | 10 kΩ (7–13 kΩ): Input bias resistor value; sets base current for predictable saturation with standard logic high levels. |
| VCEsat | ≤ −150 mV at IC = −10 mA, IB = −0.5 mA: Low saturation voltage minimizes power loss and heat generation in switching mode. |
| hFE | ≥ 30 at VCE = −5 V, IC = −5 mA: Minimum DC current gain ensures reliable forced-beta operation under worst-case conditions. |
| Tj max | 150 °C: Maximum junction temperature; enables operation in under-hood or enclosed industrial enclosures. |
| Ptot | 250 mW at Tamb ≤ 25 °C: Total power dissipation limit on FR4 PCB; derates linearly above 25 °C per Fig. 1. |
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, tin-plated leads, compatible with standard reflow and wave soldering footprints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (I) | Input (base node) | Connected internally to R1; accepts logic-level drive signal directly-no external pull-up or series resistor needed. |
| 2 (GND) | Ground (emitter node) | Emitter terminal tied to system ground; provides return path for load current and R2 feedback current. |
| 3 (O) | Output (collector node) | Switched high-side output; sinks current from load connected between VCC and pin 3 when active. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Monolithic R1 (10 kΩ) + R2 (10 kΩ) eliminates 2 external resistors and reduces PCB area by >1.5 mm². |
| Simplified logic interface | VI(on) ≤ −1.8 V ensures reliable turn-on with 3.3 V CMOS outputs; no level shifter or additional driver required. |
| Reduced assembly cost | Single-component replacement for BC847 + two 10 kΩ resistors cuts pick-and-place cycles and BOM line items. |
| Thermal robustness | Rth(j-a) = 500 K/W on standard FR4; enables sustained −100 mA switching at ambient up to 85 °C with margin. |
Applications
| Automotive Body Control Module | Industrial PLC Digital Input Stage |
|---|---|
|
Use Scenario: Switching 12 V indicator LEDs and solenoid drivers in door module PCBs. IC Role / Device Role / Timing Role: High-side load switch controlled by microcontroller GPIO. Use Value: −150 mV VCEsat limits power loss to <1.5 mW at 10 mA, reducing thermal stress in sealed enclosures. |
Use Scenario: Level-shifting and conditioning 24 V field signals into 3.3 V FPGA I/O banks. IC Role / Device Role / Timing Role: Digital input buffer with built-in pull-down and noise immunity. Use Value: R2 stabilizes base potential during transients, improving ESD immunity over discrete BJT solutions. |
| Consumer Appliance Power Sequencing | Medical Diagnostic Equipment Fan Control |
|
Use Scenario: Enabling auxiliary power rails only after main controller initialization. IC Role / Device Role / Timing Role: Enable gate for LDOs or DC-DC converters. Use Value: Guaranteed VI(off) ≥ −1.1 V prevents false turn-on from leakage or crosstalk in dense layouts. |
Use Scenario: PWM-controlled 5 V cooling fan in portable diagnostic imaging units. IC Role / Device Role / Timing Role: Low-noise, low-EMI switching element in fan drive stage. Use Value: 3 pF Cc minimizes capacitive coupling into adjacent analog sensor traces. |
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 | NPN complement with identical R1/R2 values, +50 V VCEO, +100 mA IO, same SOT23 package. | Requires inverted logic drive; suited for low-side switching where emitter ties to ground. | Select when load must be switched on the ground side or when interfacing with open-collector outputs. |
| BC807-40 | Discrete PNP BJT (no built-in resistors); hFE = 250–630; requires external R1/R2; VCEO = −45 V, IC = −500 mA. | Higher current capability but adds 2 resistors and layout complexity; less consistent VI(on) across batches. | Choose only if >100 mA load current or adjustable bias ratio is required; otherwise PDTA114ET saves space and test time. |
Compared with PDTC114ET, PDTA114ET enables high-side sourcing without polarity inversion; compared with BC807-40, it delivers deterministic turn-on behavior and reduces bill-of-materials count by three components while maintaining full compatibility with existing SOT23 footprint designs.

FAQ
What is the maximum safe operating voltage for PDTA114ET in a 24 V automotive system?
The PDTA114ET has a −50 V VCEO rating, providing 26 V headroom above nominal 24 V rail-sufficient to withstand load-dump transients up to ISO 7637-2 Pulse 5a (−120 V peak, 100 ms). Derating is not required for standard 24 V systems, but transient clamping is recommended for robust design.
Can PDTA114ET drive a 100 mA relay coil directly?
Yes-the −100 mA IO rating matches typical 5 V/12 V relay coils drawing 70–90 mA. With VCEsat ≤ −150 mV, power dissipation stays below 15 mW, well within the 250 mW Ptot limit. Ensure base drive delivers ≥ −0.5 mA (e.g., via 3.3 V MCU GPIO through ≤6.8 kΩ series resistor).
How does the built-in R2 resistor improve noise immunity?
R2 (10 kΩ) connects base to emitter, forming a local feedback path that lowers base impedance and shunts high-frequency noise away from the base-emitter junction. This reduces susceptibility to ESD-induced false triggering and improves immunity to coupled transients on adjacent traces-verified in Nexperia's IEC 61000-4-2 testing.
Is PDTA114ET qualified for automotive AEC-Q101 stress testing?
No-PDTA114ET is not AEC-Q101 qualified. It is a commercial-grade RET intended for non-safety-critical automotive subsystems (e.g., interior lighting, HVAC controls). For engine bay or ADAS applications, Nexperia's AEC-Q101 qualified equivalents like PBSS4041T must be used instead.
