Product details
Overview
PDTC114EM from Nexperia is an AEC-Q101-qualified NPN resistor-equipped transistor (RET) in SOT883 (DFN1006-3) package, featuring integrated 10 kΩ input bias resistor (R1) and 10 kΩ emitter feedback resistor (R2), 50 V VCEO, 100 mA output current, and optimized for digital switching in automotive control modules.
For engineers reviewing the PDTC114EM datasheet, PDTC114EM pinout, PDTC114EM application, or PDTC114EM equivalent, this device serves as a drop-in replacement for BC847/BC857 in load-switching and IC-input control circuits where board space, BOM count, and AEC-Q101 compliance are critical.
Technical Context
The PDTC114EM integrates a monolithic NPN transistor with two precision laser-trimmed on-die resistors-R1 connected between base and input, R2 between base and emitter-enabling single-resistor drive without external bias network. It operates as a saturated switch with guaranteed VCE(sat) ≤ 150 mV at IC = 10 mA / IB = 0.5 mA.
Its thermal resistance Rth(j-a) is 500 K/W on FR4 PCB with standard footprint, and it maintains stable hFE ≥ 30 at IC = 5 mA, VCE = 5 V, Tamb = 25 °C. The built-in resistor ratio R2/R1 is tightly controlled at 0.8–1.2, ensuring consistent turn-on/off thresholds across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports 24 V automotive rail switching with margin. |
| IO | 100 mA - Continuous output current capability; sufficient for driving LEDs, relays, and logic inputs. |
| R1 | 10 kΩ (7–13 kΩ) - Input bias resistor sets base current; enables direct microcontroller GPIO drive without external resistor. |
| R2/R1 | 1.0 (0.8–1.2) - Precise internal resistor ratio ensures stable saturation and predictable VI(on)/VI(off) behavior. |
| VCE(sat) | ≤150 mV at IC=10 mA, IB=0.5 mA - Low saturation voltage minimizes power loss and self-heating in switching mode. |
| AEC-Q101 | Qualified - Meets stress test requirements for discrete semiconductors in automotive applications (−40 °C to +125 °C). |
| Ptot | 250 mW at Tamb ≤ 25 °C - Power dissipation limit defines maximum continuous switching duty under standard PCB layout. |
Pinout & Package
Package: DFN1006-3 (SOT883), ultra-small leadless plastic package measuring 1.0 mm × 0.6 mm × 0.48 mm with 0.35 mm pitch; requires reflow soldering only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base node) | Connected internally to R1; accepts TTL/CMOS logic-level drive directly from MCU or FPGA outputs. |
| 2 | Ground (emitter) | Emitter terminal tied to system GND; provides return path for both transistor current and R2 current. |
| 3 | Output (collector) | Switched high-side load connection point; sinks up to 100 mA when driven by logic-high input. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Monolithic R1 (10 kΩ) and R2 (10 kΩ) eliminate need for two external resistors, reducing PCB area by >0.8 mm². |
| Automotive qualification | AEC-Q101 qualified per stress test standard, enabling use in engine control units, body electronics, and ADAS sensor interfaces. |
| Digital switching optimization | Guaranteed VI(on) ≤ 1.8 V and VI(off) ≥ 1.1 V ensure reliable logic-level interpretation across −40 °C to +125 °C. |
| Ultra-compact footprint | SOT883 package fits in <1 mm² area-ideal for space-constrained modules such as smart sensors and LIN bus nodes. |
| Thermal robustness | Rated junction temperature up to 150 °C and power derating curve supports sustained operation in sealed enclosures. |
Applications
| Automotive Body Control Module | Industrial PLC Digital Output |
|---|---|
|
Use Scenario: Driving LED status indicators and small solenoids in door module PCBs with limited board real estate. IC Role / Device Role / Timing Role: NPN RET acts as a logic-controlled current sink, interfacing MCU GPIO to 12 V loads. Use Value: Eliminates two external resistors per channel, reducing BOM count and placement cost while meeting AEC-Q101 requirements. |
Use Scenario: Providing isolated 24 V digital outputs for sensor actuation in DIN-rail mounted programmable logic controllers. IC Role / Device Role / Timing Role: Switching interface between low-voltage controller and industrial field devices requiring 10–100 mA drive. Use Value: Enables direct GPIO drive without level-shifting or bias networks, simplifying firmware control and improving channel density. |
| Consumer Appliance Control Board | Automotive LIN Transceiver Interface |
|
Use Scenario: Controlling buzzer activation and display backlight dimming in white-goods control boards operating at 5 V/3.3 V. IC Role / Device Role / Timing Role: Digital switch translating microcontroller logic states into audible or visual feedback signals. Use Value: Reduces component count and improves long-term reliability versus discrete transistor + resistor combinations. |
Use Scenario: Enabling/disabling LIN bus transceiver standby mode based on wake-up signal from main ECU. IC Role / Device Role / Timing Role: Low-power enable switch controlling VCC supply to LIN PHY during sleep/wake transitions. Use Value: Ensures fast, clean enable/disable edges with minimal leakage (<1 µA ICEO), preserving battery life in always-on nodes. |
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 |
|---|---|---|---|
| PDTC124EM | R1 = 22 kΩ, R2 = 47 kΩ; higher input impedance, lower base current, slower turn-on. | Better suited for high-impedance MCU outputs or battery-powered systems needing reduced quiescent current. | Select when drive strength can be relaxed and VI(on) threshold must exceed 2.0 V. |
| BC847B | No built-in resistors; requires external RB and RE; higher hFE (200–450), but no AEC-Q101 qualification. | Used in non-automotive consumer designs where cost-per-transistor is prioritized over assembly efficiency. | Choose only if full manual bias design is acceptable and automotive qualification is not required. |
Compared with PDTC124EM and BC847B, the PDTC114EM delivers optimal balance of ease-of-use (single-pin drive), automotive compliance, and 100 mA switching capability-making it the preferred choice for space-constrained, safety-aware digital control nodes.

FAQ
Is PDTC114EM compatible with reflow-only assembly processes?
Yes. The SOT883 package is qualified exclusively for reflow soldering per Nexperia's specification; wave soldering or hand-soldering is not recommended due to thermal limitations and leadless construction. Standard JEDEC J-STD-020 profile applies.
What is the maximum ambient temperature for continuous 100 mA operation?
At 100 mA output current, continuous operation is limited to approximately 75 °C ambient temperature on a standard FR4 PCB, based on the 250 mW Ptot rating and 500 K/W Rth(j-a). Derating is required above 25 °C per the published power derating curve.
Can PDTC114EM drive a 5 V relay coil directly?
Yes, provided the relay coil draws ≤100 mA and has DC resistance ≥50 Ω (to keep VCE(sat) + IC×Rcoil within 5 V supply). Its guaranteed VCE(sat) ≤150 mV ensures minimal voltage drop and efficient switching at logic-compatible currents.
How does the R2/R1 ratio affect switching behavior?
The R2/R1 ratio of 0.8–1.2 ensures stable negative feedback that prevents thermal runaway and guarantees consistent VI(on) and VI(off) thresholds. A ratio near unity provides symmetric turn-on/turn-off hysteresis, improving noise immunity in electrically noisy automotive environments.
