Product details
Overview
PDTA114TM,315 from Nexperia is a PNP resistor-equipped transistor (RET) in an ultra-small SOT883 (SC-101) package, integrating a 10 kΩ input bias resistor (R1) with R2 open. It delivers −100 mA output current, −50 V collector-emitter voltage rating, and −150 mV saturation voltage at IC = −10 mA/IB = −0.5 mA, serving as a compact digital switch for low-power logic interface and peripheral control.
For engineers reviewing the PDTA114TM,315 datasheet, PDTA114TM,315 pinout, PDTA114TM,315 application, or PDTA114TM,315 equivalent, key selection criteria include its integrated bias network, SOT883 footprint compatibility with high-density PCB layouts, thermal resistance of 500 K/W, and suitability for automotive and industrial digital signal conditioning where space and component count are constrained.
Technical Context
This device implements a monolithic PNP bipolar junction transistor with a single built-in 10 kΩ base-input resistor (R1), eliminating external bias components. Its R2 terminal is internally left open, simplifying design for fixed-gain switching applications requiring predictable turn-on behavior without emitter feedback.
Optimized for surface-mount reflow assembly only, it operates across −65 °C to +150 °C ambient and supports peak collector currents up to −100 mA in single-pulse mode. Junction temperature is limited to 150 °C, with thermal resistance from junction-to-ambient rated at 500 K/W on standard FR4 PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum safe collector-emitter voltage under open-base conditions, enabling use in 3.3 V/5 V logic-level switching with margin. |
| IO | −100 mA - Continuous output current capability, sufficient for driving LEDs, small relays, or logic inputs in portable electronics. |
| R1 | 10 kΩ (7–13 kΩ range) - Integrated base-input resistor sets defined drive current, reducing BOM count and layout area. |
| VCE(sat) | −150 mV @ IC = −10 mA, IB = −0.5 mA - Low saturation voltage minimizes power loss and heat generation in active-switching states. |
| hFE | 200 @ VCE = −5 V, IC = −1 mA - DC current gain ensures reliable saturation with modest base drive, easing microcontroller GPIO interfacing. |
| Cc | 3 pF @ VCB = −10 V - Low collector capacitance supports fast switching transitions in digital timing and pulse applications. |
| Ptot | 250 mW @ Tamb ≤ 25 °C - Power dissipation limit compatible with ultra-compact SOT883 thermal performance on standard PCBs. |
Pinout & Package
SOT883 (SC-101) is a leadless ultra-small plastic package measuring 1.0 × 0.6 × 0.5 mm with three solder lands. It enables high-density placement in space-constrained applications such as wearables and IoT sensors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected to internal 10 kΩ resistor R1; accepts logic-level input to enable PNP switching action. |
| 2 | GND (emitter) | Emitter tied to system ground reference; serves as common return path for load current. |
| 3 | Output (collector) | Switched high-side output node; sinks current from load connected between VCC and this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 bias resistor | 10 kΩ ±30 % eliminates need for external base resistor, cutting component count and PCB area by one passive part. |
| Ultra-small SOT883 footprint | 1.0 × 0.6 mm body size supports miniaturized designs in wearables, hearing aids, and compact sensor modules. |
| −100 mA output capability | Supports direct drive of medium-current loads like status LEDs, small solenoids, or level-shifting buffers without external amplification. |
| Low VCE(sat) | −150 mV ensures <150 µW conduction loss at 1 mA load, critical for battery-powered operation and thermal management. |
| Reflow-only assembly | Qualified exclusively for reflow soldering per JEDEC J-STD-020, ensuring reliability in automated SMT production lines. |
Applications
| LED Status Indication | Microcontroller GPIO Interface |
|---|---|

IC Role / Device Role / Timing Role: Constant-current source configured with emitter resistor, enabled via digital control line. Use Value: Predictable hFE of 200 and tight R1 tolerance ensure repeatable bias current across temperature and unit variance. |
Use Scenario: Activating miniature signal relays (<100 mA coil) in industrial PLC I/O modules or test equipment.

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 |
|---|---|---|---|
| PDTC114TM | NPN complement with identical SOT883 package, 10 kΩ R1, and matching −100 mA/−50 V ratings. | Requires inverted logic drive (active-high vs. active-low); unsuitable where PNP sourcing topology is mandatory. | Select PDTC114TM only when circuit architecture requires NPN low-side switching or complementary pair implementation. |
| PDTA114TK | SOT346 (SC-59A) package, same electrical specs but larger 3.0 × 1.7 mm footprint and 500 mW Ptot. | Better thermal performance and manual handling ease, but occupies >5× more board area than SOT883. | Choose PDTA114TK when thermal headroom or hand-soldering prototyping is prioritized over miniaturization. |
Compared with PDTC114TM, PDTA114TM provides native active-low switching with grounded emitter, while PDTA114TK trades size for higher power handling-making the original SOT883 variant optimal for ultra-dense, low-power digital control where footprint and current efficiency are critical.

FAQ
What is the function of the open R2 terminal in PDTA114TM,315?
The R2 terminal is internally unconnected (open), meaning only R1 (10 kΩ) is present between base and input pin. This configuration provides fixed-base biasing without emitter feedback, making it ideal for simple on/off switching where predictable turn-on threshold and minimal external parts are required.
Can PDTA114TM,315 be used in linear amplifier configurations?
No-it is optimized for digital switching, not linear operation. Its hFE is specified only at IC = −1 mA, and saturation characteristics dominate its datasheet parameters. For analog amplification, discrete transistors without built-in resistors (e.g., BC857) are recommended.
Is hand-soldering feasible for the SOT883 package of PDTA114TM,315?
SOT883 is not designed for manual soldering. The datasheet explicitly states reflow soldering is the only recommended method due to its leadless construction and thermal sensitivity. Hand-soldering risks thermal damage, solder bridging, or insufficient wetting of the 0.2 mm pitch solder lands.
How does the −50 V VCEO rating impact usage with 24 V industrial control systems?
The −50 V rating provides 2× safety margin above 24 V nominal rails, accommodating transient spikes and back-EMF from inductive loads like relays or solenoids. This makes PDTA114TM,315 suitable for 24 V digital I/O modules where robustness against voltage overshoot is essential.
