Product details
Overview
PDTA144WM from Nexperia is a PNP resistor-equipped transistor with integrated bias resistors R1 = 47 kΩ and R2 = 22 kΩ, designed for compact switching applications in space-constrained PCB layouts. It delivers −100 mA DC output current, −50 V collector-emitter breakdown voltage, and −150 mV saturation voltage at IC = −10 mA/IB = −0.5 mA, commonly used in level-shifting interface circuits for microcontroller I/O drivers.
For engineers reviewing the PDTA144WM datasheet, PDTA144WM pinout, PDTA144WM application, or PDTA144WM equivalent, key selection criteria include its SOT883 ultra-small leadless package (1.0 × 0.6 × 0.5 mm), verified PNP logic-level switching behavior, thermal resistance of 500 K/W, and compatibility with reflow-only assembly processes.
Technical Context
This device integrates two precision bias resistors (R1 = 47 kΩ, R2 = 22 kΩ) to form a monolithic PNP digital transistor, eliminating external base resistors. Its internal resistor ratio (R2/R1 ≈ 0.47) ensures stable turn-on at Vi(on) = −4 to −2.7 V and reliable cutoff at Vi(off) = −1.7 to −1.2 V under VCE = −5 V.
Designed for surface-mount operation only, it supports ambient temperatures from −65 °C to +150 °C and requires FR4 PCBs with 60 μm copper strip lines per SOT883 mounting guidelines. Junction temperature is rated up to 150 °C with total power dissipation limited to 250 mW at Tamb ≤ 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum safe collector-emitter voltage before breakdown in open-base configuration. |
| IO (DC) | −100 mA: Continuous output current capability without thermal derating at Tamb ≤ 25 °C. |
| R1 | 47 kΩ ±28%: Integrated base pull-up resistor enabling direct MCU GPIO connection without external components. |
| R2 | 22 kΩ ±28%: Integrated base-emitter resistor providing predictable turn-off behavior and noise immunity. |
| VCEsat | −150 mV at IC = −10 mA/IB = −0.5 mA: Low saturation voltage minimizes conduction loss in switching mode. |
| hFE | 60 min at VCE = −5 V/IC = −5 mA: Guaranteed DC current gain ensures reliable amplification in linear-region biasing. |
| Cc | 3 pF at VCB = −10 V/f = 1 MHz: Low collector capacitance supports >100 MHz switching in high-speed digital interfaces. |
Pinout & Package
SOT883 is a leadless ultra-small plastic package measuring 1.0 × 0.6 × 0.5 mm with three solder lands; optimized for high-density routing and automated reflow assembly only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Internal connection to R1 and R2 network; accepts logic-level input for controlled PNP switching. |
| 2 | Emiter | Common emitter node tied to system ground or low-side reference; carries full load current. |
| 3 | Collector | High-side switched output node; connects to load supply rail and drives external circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in bias resistors | Eliminates need for two external SMT resistors, reducing BOM count and PCB area by ≥2.5 mm². |
| Reflow-only assembly | Qualified exclusively for reflow soldering per JEDEC J-STD-020, preventing mechanical stress damage during through-hole alternatives. |
| Low thermal resistance | Rth(j-a) = 500 K/W enables sustained −100 mA operation on standard FR4 without heatsinking. |
| Controlled input thresholds | Vi(on) = −4 to −2.7 V and Vi(off) = −1.7 to −1.2 V ensure robust interfacing with 3.3 V and 5 V logic families. |

The PDTA144W series belongs to Nexperia's resistor-equipped transistor product line, engineered specifically for space-constrained digital switching applications where board area, assembly cost, and signal integrity are critical design constraints.
FAQ
Is PDTA144WM compatible with lead-free reflow processes?
Yes, PDTA144WM is qualified for lead-free reflow soldering per JEDEC J-STD-020, with peak temperature tolerance up to 260 °C. The SOT883 package uses matte tin plating and is not rated for wave or hand soldering. Thermal profile must follow Nexperia's recommended ramp rates and time-above-liquidus limits to avoid delamination.
What is the maximum operating frequency for switching applications?
PDTA144WM supports switching frequencies up to 100 MHz in small-signal applications, based on its 3 pF collector capacitance and typical transition frequency (fT) of 100 MHz specified for similar PNP RETs in the PDTA144W series. For high-current switching (>50 mA), practical limits are ~10 MHz due to stored charge and saturation recovery time.
Can PDTA144WM replace a discrete PNP transistor plus two resistors?
Yes, PDTA144WM directly replaces a BC807-16 or similar PNP transistor plus 47 kΩ and 22 kΩ external bias resistors. Pinout matches standard SOT883 layout (Base–Emitter–Collector), and electrical behavior-including Vi(on), Vi(off), and VCEsat-is functionally identical to the discrete implementation, with improved matching and reduced parasitics.
Does this part have automotive qualification?
No, PDTA144WM is not AEC-Q101 qualified. It is rated for industrial temperature range (−65 °C to +150 °C) but lacks the extended reliability testing, failure analysis reporting, and traceability required for automotive applications. For automotive use, Nexperia's PBSS4041PAS or similar AEC-Q101 PNP RETs are recommended alternatives.
