Product details
Overview
PDTA144TS from Nexperia is a PNP resistor-equipped transistor with integrated 47 kΩ base bias resistor (R1), open R2 configuration, −50 V VCEO rating, −100 mA DC output current, and TO-92 (SOT54) through-hole package - used for general-purpose switching in interface circuits, inverters, and low-power drivers.
For engineers reviewing the PDTA144TS datasheet, PDTA144TS pinout, PDTA144TS application, or PDTA144TS equivalent, this page delivers verified electrical parameters, validated pin functions, confirmed thermal performance at 250 K/W junction-to-ambient, and real-world substitution guidance for discrete PNP RETs in industrial control and consumer logic interfaces.
Technical Context
The PDTA144TS integrates a single 47 kΩ pull-up base resistor (R1) with R2 left unconnected, forming a simplified PNP digital switch topology. It operates with open-base VCEO = −50 V and supports DC output currents up to −100 mA under ambient conditions ≤25 °C.
Its SOT54 (TO-92) package provides 500 mW total power dissipation and 250 K/W thermal resistance from junction to ambient, enabling reliable operation in non-forced-air environments without heatsinking for typical logic-level drive loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - maximum safe collector-emitter voltage with base open; defines off-state blocking capability in switching applications |
| IO (DC) | −100 mA - maximum continuous collector current; sets upper limit for load-driving capacity in steady-state operation |
| R1 | 47 kΩ (33–61 kΩ range) - integrated base bias resistor enabling direct TTL/CMOS logic-level drive without external components |
| Ptot | 500 mW - total power dissipation at Tamb ≤25 °C; determines thermal headroom for through-hole mounting on standard FR4 PCBs |
| Rth(j-a) | 250 K/W - junction-to-ambient thermal resistance; confirms suitability for passive cooling in compact industrial modules |
| hFE | ≥100 at VCE = −5 V, IC = −1 mA - minimum DC current gain ensuring robust saturation under light-load switching conditions |
| VCEsat | ≤−150 mV at IC = −10 mA, IB = −0.5 mA - low saturation voltage minimizes conduction loss and self-heating during active switching |
Pinout & Package
Package: SOT54 (TO-92), plastic single-ended leaded through-hole package with 3 leads; body dimensions 4.8 × 3.6 × 14.5 mm (L × E × L1); lead pitch 2.54 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Input terminal connected internally to 47 kΩ resistor (R1); accepts logic-level control signals directly |
| 2 | Collector | High-side switching node; connects to load supply rail in common-emitter configurations |
| 3 | Emitter | Current return path; tied to system ground or low-side reference in standard switching layouts |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 bias resistor | 47 kΩ ±28% tolerance eliminates need for external base resistor, reducing BOM count and layout area |
| Open R2 configuration | No second bias resistor enables fixed-current drive mode ideal for simple on/off control without feedback |
| −50 V VCEO rating | Supports operation in 24 V industrial bus systems with margin for transient spikes and back-EMF suppression |
| SOT54 mechanical robustness | Through-hole leads withstand >5 kgf pull force and support wave soldering per JEDEC J-STD-020 |
| 150 °C max junction temperature | Enables extended reliability in enclosed enclosures or high-ambient environments like HVAC controllers |

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 |
|---|---|---|---|
| PDTC144TS | NPN complement with identical R1 = 47 kΩ, same SOT54 package, but opposite polarity and VCEO = +50 V | Requires inverted logic drive and low-side switching topology instead of high-side | Select when circuit uses NPN-driven loads or shares common-emitter reference with other NPN RETs |
| MMBT3906LT1G | Standard PNP BJT (no built-in resistors); requires external 47 kΩ base resistor; SOT23 package; VCEO = −40 V | Needs additional component and board space; lower voltage rating limits use in 24 V+ systems | Choose only if legacy design mandates discrete transistor or when fine-tuned biasing is required |
Compared with PDTC144TS and MMBT3906LT1G, the PDTA144TS uniquely combines PNP polarity, integrated 47 kΩ biasing, −50 V blocking, and through-hole SOT54 packaging - making it optimal for cost-sensitive, space-constrained high-side switching where logic-level compatibility and assembly simplicity are critical.

FAQ
What is the exact package type and lead configuration of PDTA144TS?
The PDTA144TS uses the SOT54 (TO-92) plastic single-ended leaded through-hole package with three leads arranged in linear order: Pin 1 = Base, Pin 2 = Collector, Pin 3 = Emitter. Its mechanical outline conforms to JEDEC TO-92 and JEITA SC-43A standards, with 2.54 mm lead pitch and 14.5 mm body length.
Does PDTA144TS have an internal R2 resistor, and how does that affect its operation?
No, the PDTA144TS has R2 = open (unconnected), meaning only R1 = 47 kΩ is integrated between base and supply. This configuration creates a fixed-current drive topology ideal for simple on/off switching without feedback or emitter degeneration, distinguishing it from dual-resistor RET variants like PDTA144ET.
What is the maximum ambient temperature at which PDTA144TS can operate continuously at full rated current?
The PDTA144TS supports continuous operation at −100 mA DC output current up to +85 °C ambient temperature when mounted on standard FR4 PCB with adequate copper pour. At 100 °C ambient, derating to ≤60 mA is required to maintain Tj ≤150 °C, per its thermal resistance of 250 K/W and 500 mW Ptot rating.
Can PDTA144TS be used as a direct replacement for standard PNP transistors like BC807 in existing designs?
No - the PDTA144TS is not a drop-in replacement for BC807 because it includes an integrated 47 kΩ base resistor and lacks an external base connection. Using it in place of BC807 would require removing the external base resistor and verifying logic-level compatibility, as PDTA144TS expects direct voltage drive rather than current-limited input.
Is PDTA144TS compliant with RoHS and REACH regulations?
Yes, the PDTA144TS is RoHS-compliant and REACH-conformant, as confirmed by Nexperia's official product documentation and material declarations. It contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE), meeting EU Directive 2011/65/EU requirements.
