Product details
Overview
PDTA114TU,115 from Nexperia is a PNP resistor-equipped transistor (RET) in SOT323 (SC-70) package, designed for digital switching applications with integrated 10 kΩ base bias resistor (R1), −50 V VCEO, −100 mA IO, and −150 mV VCEsat at IC = −10 mA / IB = −0.5 mA - used in low-power logic-level interface circuits such as microcontroller GPIO drivers and LED control stages.
For engineers reviewing the PDTA114TU,115 datasheet, PDTA114TU,115 pinout, PDTA114TU,115 application, or PDTA114TU,115 equivalent, key selection criteria include guaranteed R1 tolerance (7–13 kΩ), thermal resistance (625 K/W), SC-70 footprint compatibility, and direct replacement suitability for BC857-based digital switch designs.
Technical Context
This PNP RET integrates a single 10 kΩ input bias resistor (R1) with open-circuit R2, eliminating external base resistors in saturated-switch configurations. Its −50 V VCEO and −100 mA output current support robust operation in 3.3 V/5 V logic-controlled loads.
The device operates with hFE ≥ 200 at IC = −1 mA and VCE = −5 V, and achieves VCEsat ≤ −150 mV under standard drive conditions - enabling fast, low-loss switching in space-constrained PCB layouts using SC-70 packaging.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - maximum collector-emitter voltage before breakdown; supports 3.3 V/5 V rail-to-rail digital interfacing without derating |
| IO | −100 mA - continuous DC output current capability; sufficient for driving LEDs, small relays, or logic inputs |
| R1 | 10 kΩ (7–13 kΩ range) - built-in base bias resistor; eliminates need for external pull-up/pull-down components |
| VCEsat | −150 mV @ IC = −10 mA, IB = −0.5 mA - low saturation voltage minimizes power loss and self-heating in switching mode |
| Ptot | 200 mW @ Tamb ≤ 25 °C - thermal limit compatible with standard FR4 PCBs and reflow soldering profiles |
| Rth(j-a) | 625 K/W - junction-to-ambient thermal resistance; defines temperature rise per watt in free-air mounting |
| hFE | ≥ 200 @ VCE = −5 V, IC = −1 mA - ensures reliable saturation with minimal base drive current |
Pinout & Package
SOT323 (SC-70) plastic surface-mounted package; 3-lead, 1.3 mm × 2.1 mm × 0.95 mm body; moisture sensitivity level (MSL) 1 per JEDEC J-STD-020.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts TTL/CMOS logic-level signals directly without external bias network |
| 2 | GND (emitter) | Common reference node; tied to system ground in PNP high-side switch or inverter configurations |
| 3 | Output (collector) | Switched output node; sinks current from load connected between VCC and collector when active |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 bias resistor | 10 kΩ ±30 % - reduces BOM count by one passive component and eliminates placement error risk |
| SC-70 footprint | 1.3 × 2.1 mm - enables high-density routing in portable and IoT edge devices with limited board area |
| Low VCEsat | ≤ −150 mV - limits power dissipation to <1.5 mW at 10 mA load, supporting thermally constrained designs |
| High hFE | ≥ 200 - allows full saturation with ≤0.5 mA base current, easing drive requirements from weak GPIOs |
| Reflow-compatible | Rated for lead-free reflow per JEDEC J-STD-020 - supports modern automated assembly without special process adjustments |
Applications
| Microcontroller GPIO Driver | LED Indicator Control |
|---|---|
|
Use Scenario: Driving discrete LEDs from 3.3 V MCU outputs with current limiting via collector resistor. IC Role / Device Role / Timing Role: PNP switch configured as low-side sink; turns on LED when MCU pin goes low. Use Value: Eliminates need for external base resistor, reducing layout complexity and improving production yield in high-volume consumer electronics. |
Use Scenario: Controlling status LEDs in battery-powered wearables where board space and power efficiency are critical. IC Role / Device Role / Timing Role: Digital on/off switch with fast turn-on/turn-off response (<100 ns typical propagation delay). Use Value: SC-70 package saves >40 % board area vs. SOT23; low VCEsat extends battery life by minimizing voltage drop across switch. |
| Logic-Level Signal Inverter | Small-Signal Load Switch |
|
Use Scenario: Converting active-high logic signals to active-low outputs for legacy peripherals or optocoupler inputs. IC Role / Device Role / Timing Role: Single-transistor inverter stage with fixed gain and predictable switching threshold. Use Value: Integrated R1 ensures consistent inversion behavior across temperature and voltage variations, avoiding manual resistor matching. |
Use Scenario: Enabling/disabling power to low-current sensors or communication ICs in industrial sensor nodes. IC Role / Device Role / Timing Role: High-side load switch controlled by microcontroller output; emitter tied to VCC, collector to load. Use Value: −100 mA rating supports typical sensor supply currents (e.g., I²C transceivers, analog front-ends); low leakage (ICEO ≤ −1 µA) prevents standby drain. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP digital switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTC114TU | NPN complement; same SC-70 package, identical R1 value (10 kΩ), but opposite polarity | Requires inverted logic control signal; suited for low-side switching instead of high-side | Select PDTC114TU when load connects to ground and MCU drives high to activate |
| BC857BW | Standard PNP BJT without integrated resistor; requires external 10 kΩ base resistor | Higher BOM count and layout area; offers adjustable bias for non-saturated or linear operation | Choose BC857BW only if variable base current or analog gain control is required |
Compared with PDTC114TU and BC857BW, PDTA114TU,115 delivers plug-and-play digital switching in SC-70 with zero external components, while maintaining identical thermal and electrical specs - making it optimal for cost-sensitive, high-volume digital interface designs.

FAQ
What is the function of the internal resistor in PDTA114TU,115?
The internal 10 kΩ resistor (R1) connects between pin 1 (base) and the internal transistor base, providing automatic biasing for saturated switching. It eliminates the need for an external base resistor when driven by logic-level signals, ensuring reliable turn-on with standard CMOS/TTL outputs and reducing PCB component count.
Can PDTA114TU,115 replace BC857 in existing designs?
Yes - PDTA114TU,115 is a direct functional replacement for BC857 in digital switching applications, provided the circuit uses the transistor as a saturated switch with fixed base bias. The SC-70 footprint matches BC857BW, and the integrated R1 replicates the typical 10 kΩ external resistor used with BC857, simplifying layout and assembly.
What is the maximum operating temperature for continuous use?
PDTA114TU,115 has a maximum junction temperature (Tj) of 150 °C and storage temperature range of −65 °C to +150 °C. For continuous operation at rated 200 mW power dissipation, ambient temperature must remain ≤25 °C; derating is required above that point per the 625 K/W thermal resistance specification.
Is PDTA114TU,115 suitable for analog amplifier applications?
No - PDTA114TU,115 is optimized for digital switching, not linear amplification. Its fixed R1 resistor prevents independent bias adjustment, and its hFE is specified only at IC = −1 mA. For analog gain stages, use standard BJTs like BC857 without integrated resistors to enable precise DC biasing and AC coupling.
