Product details
Overview
PDTA115ET from NXP Semiconductors is a PNP resistor-equipped transistor (RET) with integrated 100 kΩ base bias resistors (R1 = R2 = 100 kΩ), designed for simplified switching in low-power digital interface and logic-level translation circuits. It features −50 V VCEO, −20 mA IO (DC), −150 mV VCEsat at IC = −5 mA/IB = −0.25 mA, and operates in SOT23 package with 1–2–3 pinout (base–emitter–collector). Commonly used in microcontroller GPIO driver stages and level-shifting inverters.
For engineers reviewing the PDTA115ET datasheet, PDTA115ET pinout, PDTA115ET application, or PDTA115ET equivalent, key selection criteria include verified PNP RET functionality, confirmed 100 kΩ input resistor matching, validated SOT23 thermal resistance (500 K/W), and compatibility with reflow-only assembly per NXP specification.
Technical Context
This device integrates two precision 100 kΩ bias resistors (R1 from base to emitter, R2 from base to collector) to eliminate external components in saturated-switch configurations. Its PNP structure enables active-low control with direct connection to 3.3 V/5 V logic outputs.
It delivers guaranteed hFE ≥ 80 at IC = −5 mA and VCE = −5 V, supports −100 mA ICM peak current, and maintains VI(off) ≤ −1.2 V and VI(on) ≤ −1.6 V for robust noise margin in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum safe collector-emitter voltage under open-base condition |
| IO (DC) | −20 mA - Continuous DC output current capability without derating at Tamb ≤ 25 °C |
| R1 / R2 | 100 kΩ ±30% - Matched internal bias resistors enabling single-resistor-free switch design |
| VCEsat | −150 mV - Low saturation voltage ensures minimal power loss and heat generation in on-state |
| hFE | ≥80 - Minimum DC current gain at −5 mA collector current, ensuring reliable drive margin |
| Thermal Rth(j-a) | 500 K/W - Junction-to-ambient thermal resistance in standard SOT23 mounting, defining power derating slope |
| VI(on) | −3 V to −1.6 V - Input-on voltage range confirming compatibility with TTL and CMOS logic thresholds |
Pinout & Package
Package: SOT23 (TO-236AB), plastic surface-mounted package; 3 leads, body size 1.1 × 0.9 × 1.3 mm. Standard reflow soldering only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Input node connected internally to both R1 and R2; accepts logic-level control signal |
| 2 | Emitter | Common reference terminal tied to VCC (for PNP high-side switching) or logic rail |
| 3 | Collector | Switched output node; sinks current when base is pulled low relative to emitter |
Key Features
| Feature | Design Value |
|---|---|
| Built-in matched bias resistors | Eliminates two external 100 kΩ resistors, reducing BOM count and PCB footprint by ~3 mm² |
| SOT23 reflow-compatible packaging | Enables automated assembly with industry-standard lead-free reflow profiles (per NXP note 2) |
| Guaranteed VCEsat ≤ −150 mV | Ensures <150 μW dissipation at 1 mA load, critical for battery-powered sensor interface stages |
| −65 °C to +150 °C operating range | Supports deployment in automotive under-hood and industrial control cabinet environments |
| Low input capacitance (Cc = 3 pF) | Minimizes propagation delay in high-speed digital switching (<10 ns rise/fall typical) |
Applications
| Microcontroller GPIO Driver | Logic-Level Inverter |
|---|---|
Use Scenario: Driving LED indicators or small relays directly from 3.3 V MCU pins with no external resistors. IC Role / Device Role / Timing Role: PNP switch configured as low-side sink, activated when MCU pin goes low. Use Value: Reduces component count by two 100 kΩ resistors and saves 2.5 mm × 1.3 mm PCB area per channel. |
Use Scenario: Converting active-high logic signals (e.g., UART TX) to active-low outputs for legacy peripherals. IC Role / Device Role / Timing Role: Single-transistor inverter stage with fixed bias network ensuring stable DC transfer characteristics. Use Value: Achieves <100 ns propagation delay and eliminates resistor tolerance drift affecting switching threshold. |
| Industrial Sensor Interface | Power Rail Enable Switch |
Use Scenario: Level-shifting and buffering analog sensor enable signals in 24 V PLC I/O modules. IC Role / Device Role / Timing Role: Signal translator isolating 3.3 V controller logic from higher-voltage field-side circuitry. Use Value: Withstands −50 V VCEO and −10 V VEBO, enabling safe operation across common-mode transients up to ±2 kV. |
Use Scenario: Controlling 5 V or 12 V power rails for peripheral ICs using a 3.3 V enable signal. IC Role / Device Role / Timing Role: High-side PNP switch where emitter connects to supply rail and collector feeds load. Use Value: −20 mA IO rating supports driving >100 µF bulk capacitance with controlled inrush via VCEsat-limited current. |
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 |
|---|---|---|---|
| PDTC115ET | NPN complement with identical R1/R2 values and SOT23 package; requires inverted logic drive | Used where active-high control is preferred or where sourcing (not sinking) current is required | Select when interfacing with open-collector/drain outputs or when load must be connected to ground |
| NSV11501T1G | ON Semiconductor PNP RET with R1 = 100 kΩ, R2 = 100 kΩ but rated for −100 mA ICM and −60 V VCEO | Supports higher surge currents and wider supply voltage margins in harsher environments | Choose for designs requiring extended absolute maximum ratings beyond NXP's −50 V/−100 mA limits |
Compared with PDTC115ET and NSV11501T1G, PDTA115ET offers optimal balance of cost, footprint, and verified performance for standard 3.3 V/5 V logic interfacing-whereas PDTC115ET shifts polarity requirements, and NSV11501T1G adds overhead for non-critical ruggedness.

FAQ
Is PDTA115ET compatible with lead-free reflow soldering?
Yes. NXP explicitly specifies reflow soldering as the only recommended method for PDTA115ET (SOT23 package), and the device is qualified for standard lead-free reflow profiles including JEDEC J-STD-020 moisture sensitivity level 1. No pre-baking is required for dry-packed units.
What is the exact pin configuration for PDTA115ET in SOT23?
PDTA115ET uses standard SOT23 pinout: Pin 1 = Base, Pin 2 = Emitter, Pin 3 = Collector. This is confirmed in the "Simplified outline, symbol and pinning" section of the NXP datasheet (page 4), and matches SOT23 mechanical drawing revision 04-11-04.
Can PDTA115ET replace a discrete PNP transistor plus two 100 kΩ resistors?
Yes-exactly. The internal R1 (base–emitter) and R2 (base–collector) resistors are both 100 kΩ ±30%, matching typical discrete bias networks. Layout savings include elimination of two 0603/0805 resistors and associated traces, with no change to circuit function or bias point.
Does PDTA115ET support operation at 125 °C ambient temperature?
Yes. Its specified operating ambient temperature range is −65 °C to +150 °C, and junction temperature is rated to 150 °C. At Tamb = 125 °C, derated power dissipation is 125 mW (based on 500 K/W Rth(j-a)), sufficient for ≤12.5 mA DC load at −150 mV VCEsat.
