Product details
Overview
PDTC114YT-QVL from Nexperia is an AEC-Q101-qualified NPN resistor-equipped transistor (RET) in SOT23 package, featuring integrated 10 kΩ input bias resistor (R1) and 47 kΩ feedback resistor (R2), rated for 50 V VCEO and 100 mA output current, used as a digital switch for IC input control and load switching in automotive ECUs.
For engineers reviewing the PDTC114YT-QVL datasheet, PDTC114YT-QVL pinout, PDTC114YT-QVL application, or PDTC114YT-QVL equivalent, this part serves as a drop-in replacement for BC847-Q series in digital logic interface circuits where built-in biasing reduces PCB footprint and eliminates discrete base resistors.
Technical Context
This RET integrates an NPN transistor with two monolithically embedded silicon resistors-R1 connected between base and input, R2 between base and emitter-enabling single-pin digital drive without external bias components. It operates with VI(on) ≤ 0.8 V at IC = 1 mA and VI(off) ≥ 0.7 V at IC = 100 µA, ensuring robust noise immunity in 3.3 V/5 V logic environments.
The device delivers hFE ≥ 100 at VCE = 5 V and IC = 5 mA, with VCE(sat) ≤ 100 mV under IC = 5 mA / IB = 0.25 mA conditions, supporting low-loss switching in power-constrained automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports 12 V automotive rail with margin for transients. |
| IO | 100 mA - Continuous output current capability; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 | 10 kΩ ±30% - Input bias resistor enabling direct connection to microcontroller GPIO without external pull-up/down. |
| R2/R1 ratio | 4.7 - Fixed internal feedback ratio; sets stable DC bias point and improves turn-off speed vs. single-resistor RETs. |
| VCE(sat) | ≤100 mV at IC=5 mA - Low saturation voltage minimizes power loss and self-heating in high-duty-cycle switching. |
| hFE | ≥100 at IC=5 mA - Ensures reliable current gain across -40°C to 125°C ambient range per AEC-Q101 qualification. |
| Tj(max) | 150 °C - Junction temperature limit enabling operation in under-hood automotive environments. |
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, FR4-compatible footprint per Fig. 11–12.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base via R1) | Direct connection point for digital control signal; internal R1 pulls base toward input voltage. |
| 2 | Ground (emitter) | Emitter tied to system ground; provides return path for load current and R2 reference. |
| 3 | Output (collector) | Switched high-side output node; connects to load (e.g., LED anode or relay coil) referenced to VCC. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Qualified for automotive applications including engine control, body electronics, and ADAS sensor interfaces. |
| Integrated R1 + R2 network | Eliminates two external resistors, reducing BOM count, PCB area, and placement cost in high-volume SMT assembly. |
| VI(on)/VI(off) separation | ≥0.1 V margin between on/off thresholds ensures noise-immune switching in electrically noisy vehicle cabins. |
| Thermal resistance Rth(j-a) | 500 K/W on standard FR4 PCB - enables 250 mW Ptot derating up to +70°C ambient without heatsinking. |
| Complementary PNP part | PDTA114YT available for push-pull or level-shifting topologies requiring matched bias networks. |
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: Digital output switch interfacing MCU GPIO to higher-current loads. Use Value: Built-in R1/R2 eliminates need for discrete biasing, reducing component count by 2 per channel and improving layout density. |
Use Scenario: Level-shifting 24 V field signals to 3.3 V FPGA or microcontroller inputs. IC Role / Device Role / Timing Role: Input conditioning transistor with defined VI(on)/VI(off) thresholds for noise rejection. Use Value: Guaranteed VI(off) ≥ 0.7 V prevents false triggering from EMI spikes common in factory-floor wiring. |
| Automotive HVAC Control Panel | Consumer Appliance Motor Driver Interface |
Use Scenario: Driving backlight segments and tactile feedback buzzers in climate control UI. IC Role / Device Role / Timing Role: Low-power load switch with fast turn-on (<100 ns typical) and minimal quiescent current. Use Value: VCE(sat) ≤ 100 mV limits power dissipation to <1 mW at 10 mA, extending battery life in always-on modules. |
Use Scenario: Enabling/disabling small DC fan motors in smart refrigerators and washing machines. IC Role / Device Role / Timing Role: General-purpose digital switch replacing BC847-Q in cost-sensitive white-goods designs. Use Value: Identical SOT23 footprint and electrical specs allow direct substitution without layout changes or requalification. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847B-Q | No integrated resistors; requires external R1/R2; hFE = 200–450 (wider spread); same SOT23 footprint. | Higher gain variability increases design margining effort; lacks AEC-Q101 certification. | Select when tighter hFE control is needed and external biasing is acceptable. |
| PDTA114YT | PNP complement with identical R1/R2 values and AEC-Q101 rating; VCEO = −50 V; IO = −100 mA. | Used in high-side switching or complementary pair configurations-not a functional substitute for NPN operation. | Select only for push-pull output stages or inverted logic interfaces requiring matched bias networks. |
Compared with BC847B-Q and PDTA114YT, PDTC114YT-QVL uniquely combines AEC-Q101 compliance, guaranteed R1/R2 ratio, and zero-external-component operation-making it optimal for automotive digital I/O where reliability, space, and qualification are non-negotiable.

FAQ
Is PDTC114YT-QVL pin-compatible with BC847B-Q?
Yes-both use the SOT23 package with identical pin 1 (collector), pin 2 (base), pin 3 (emitter) assignment. However, PDTC114YT-QVL has internal R1/R2 connected to pin 1 (input) and pin 2 (ground), while BC847B-Q has bare base/emitter/collector. Layout must route pin 1 to control signal and pin 2 to ground, not base drive.
What is the maximum operating temperature for continuous use?
PDTC114YT-QVL is rated for continuous operation up to +150 °C junction temperature. On a standard FR4 PCB, its thermal resistance Rth(j-a) = 500 K/W allows full 100 mA output up to +70 °C ambient; above that, current must be derated per Fig. 1 in the datasheet.
Can PDTC114YT-QVL drive a 5 V relay coil directly?
Yes-if the relay coil draws ≤100 mA at 5 V and has DC resistance ≥50 Ω. With VCE(sat) ≤ 100 mV, the transistor drops <0.1 V, leaving ≥4.9 V across the coil. Confirm coil inrush current does not exceed 100 mA peak, and add flyback diode protection.
Does PDTC114YT-QVL require a pull-down resistor on the input pin?
No-R1 internally connects pin 1 (input) to the base, and R2 connects base to pin 2 (emitter/ground). When pin 1 is left floating, R1 pulls the base low through R2, ensuring the transistor remains off. No external pull-down is needed for default-off behavior.
