Product details
Overview
PDTA144EE from Nexperia is a PNP resistor-equipped transistor (RET) in SOT416 (SC-75) package, designed for digital switching applications with built-in bias resistors R1 = 47 kΩ and R2 = 47 kΩ, −50 V collector-emitter voltage rating, −100 mA output current capability, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PDTA144EE datasheet, PDTA144EE pinout, PDTA144EE application, or PDTA144EE equivalent, this device serves as a space- and cost-optimized replacement for discrete BJT + resistor networks in IC input control and low-power load switching circuits where simplified layout and reduced component count are critical.
Technical Context
The PDTA144EE integrates a PNP bipolar transistor with two precision internal bias resistors (R1 = 47 kΩ, R2 = 47 kΩ; ratio 0.8–1.2), enabling direct logic-level drive without external base components. Its on-state input voltage VI(on) is −1.6 V typical at IC = −2 mA, and off-state input voltage VI(off) is −1.2 V typical at IC = −100 μA.
It operates with VCE(sat) ≤ −150 mV at IC = −10 mA/IB = −0.5 mA, supports ambient temperatures from −65 °C to +150 °C, and features a junction-to-ambient thermal resistance of 830 K/W in free air on FR4 PCB - optimized for ultra-small footprint reliability in high-density automotive and industrial PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum safe collector-emitter voltage under open-base conditions; defines voltage headroom for automotive 12 V and 24 V rail switching. |
| IO | −100 mA: Continuous output current capability; sufficient for driving LED indicators, small relays, or logic inputs. |
| R1 / R2 | 47 kΩ / 47 kΩ: Matched internal base bias network eliminates need for external resistors, reducing BOM count and layout area. |
| VCE(sat) | ≤ −150 mV at IC = −10 mA: Low saturation voltage minimizes power loss and heat generation in switching mode. |
| hFE | ≥ 80 at VCE = −5 V, IC = −5 mA: Ensures reliable current amplification for predictable digital on/off behavior. |
| AEC-Q101 | Qualified: Validated for automotive-grade reliability including temperature cycling, humidity, and mechanical stress per AEC standard. |
Pinout & Package
SOT416 (SC-75) ultra-small surface-mount plastic package: 1.8 mm × 0.95 mm × 0.6 mm body, 3-lead configuration with gull-wing leads, optimized for high-density placement and reflow soldering only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | input (base) | Connected internally to R1 and R2; accepts logic-level input signal to control transistor conduction state. |
| 2 | GND (emitter) | Emitting terminal tied to system ground or low-side reference; forms common return path for switched load current. |
| 3 | output (collector) | Switched output node delivering −100 mA sink current to load; connected to load's high-side supply rail. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in bias resistors | Eliminates two external resistors, reducing PCB area by ~1.5 mm² and eliminating pick-and-place steps for passive components. |
| −100 mA output current | Supports direct drive of moderate-current loads such as status LEDs, small solenoids, or CMOS/TTL input stages without external amplification. |
| AEC-Q101 qualification | Validated for automotive under-hood and infotainment environments, ensuring long-term stability across −40 °C to +125 °C operating range. |
| Ultra-small SOT416 package | 0.95 mm width enables routing between fine-pitch ICs; compatible with standard 4 mm pitch tape-and-reel handling (order code -115). |
Applications
| Automotive Interior Lighting Control | Industrial Sensor Interface |
|---|---|
Use Scenario: Switching 12 V LED strings in dashboard backlighting or door courtesy lighting modules. IC Role / Device Role / Timing Role: PNP RET acts as low-side switch controlling current flow from 12 V rail through LED load to ground. Use Value: Built-in resistors enable direct MCU GPIO drive without external components, reducing bill-of-materials and improving assembly yield. | Use Scenario: Level-shifting and conditioning digital signals from analog sensors (e.g., temperature, pressure) before ADC input. IC Role / Device Role / Timing Role: Digital buffer isolating sensor output from microcontroller input while providing noise immunity and current limiting. Use Value: VI(on)/VI(off) thresholds ensure clean logic transitions even with noisy sensor outputs; AEC-Q101 rating supports harsh industrial environments. |
| Consumer Appliance Power Sequencing | IoT Edge Node Load Management |
Use Scenario: Enabling/disabling auxiliary power rails (e.g., display backlight, audio amplifier) during boot-up or sleep mode in smart appliances. IC Role / Device Role / Timing Role: Discrete PNP switch controlled by system controller to gate power to subsystems. Use Value: −50 V VCEO provides margin against voltage transients; compact SOT416 footprint saves space on crowded mainboard layouts. | Use Scenario: Managing battery-powered peripheral loads (e.g., BLE radio enable, sensor bias) in compact wireless sensor nodes. IC Role / Device Role / Timing Role: Low-quiescent-current digital switch enabling precise duty-cycled operation to extend battery life. Use Value: ≤ −150 mV VCE(sat) minimizes conduction loss; −100 mA rating supports intermittent peak loads up to 50 mA average. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP digital switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTC144EE | NPN complement with identical R1/R2 values (47 kΩ), same SOT416 package, but opposite polarity and logic drive requirements. | Requires inverted control signal; used where high-side sourcing (vs. low-side sinking) is preferred or where NPN interface matches upstream logic. | Select PDTC144EE when circuit topology demands NPN sink configuration or compatibility with existing NPN-based reference designs. |
| BC857B,115 | Discrete PNP BJT (no integrated resistors); requires two external base resistors; higher board area and assembly cost. | Offers higher hFE (120–250) and slightly better VCE(sat), but increases design complexity and test points for bias network validation. | Choose BC857B,115 only if adjustable bias or higher gain is required; otherwise PDTA144EE reduces risk and cost in volume production. |
Compared with PDTC144EE, PDTA144EE provides complementary polarity for low-side switching with identical footprint and resistor values; versus BC857B,115, it eliminates two passives and associated layout/manufacturing overhead while maintaining automotive qualification and robust digital switching performance.

FAQ
What is the maximum collector-emitter voltage rating for PDTA144EE?
The PDTA144EE has a maximum collector-emitter voltage (VCEO) rating of −50 V under open-base conditions. This rating ensures safe operation in 12 V and 24 V automotive and industrial systems with transient margin. Exceeding this voltage may cause permanent breakdown. The value is specified in Table 2 (Quick reference data) and Table 6 (Limiting values) of the official Nexperia datasheet Rev. 8.
Does PDTA144EE require external base resistors for digital switching?
No, PDTA144EE does not require external base resistors. It integrates R1 = 47 kΩ and R2 = 47 kΩ internally, forming a complete bias network that enables direct connection to logic-level control signals. This eliminates two external components and simplifies PCB layout - confirmed in Section 1.4 (Quick reference data) and Table 2 of the PDTA144E_SER datasheet.
Is PDTA144EE qualified for automotive applications?
Yes, PDTA144EE is AEC-Q101 qualified, as explicitly stated in Section 8.1 (Quality information) of the datasheet. This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and other automotive environmental requirements, making PDTA144EE suitable for under-hood and cabin electronics where reliability is critical.
What is the thermal resistance (Rth(j-a)) of PDTA144EE in free air?
The thermal resistance from junction to ambient (Rth(j-a)) for PDTA144EE is 830 K/W in free air on an FR4 PCB with single-sided copper and standard footprint, per Table 7 of the datasheet. This value guides thermal design for continuous operation at ambient temperatures up to +125 °C, assuming no additional heatsinking or airflow.
What package type and marking code correspond to PDTA144EE?
PDTA144EE uses the SOT416 (JEITA: SC-75) ultra-small surface-mount package and is marked with the code "07" on the device top surface, as documented in Tables 3 (Pinning), 4 (Ordering information), and 5 (Marking codes) of the Nexperia PDTA144E_SER datasheet Rev. 8.
