Product details
Overview
PDTA123TM from Nexperia is a PNP resistor-equipped transistor (RET) with integrated 2.2 kΩ base bias resistor, designed for digital switching in space-constrained PCB layouts. It delivers −100 mA output current, −50 V collector-emitter voltage rating, and operates in SOT883 (SC-101) ultra-small leadless package measuring 1.0 × 0.6 × 0.5 mm - used in portable logic-level interface circuits and low-power load control.
For engineers reviewing the PDTA123TM datasheet, PDTA123TM pinout, PDTA123TM application, or PDTA123TM equivalent, key selection criteria include built-in R1 value (2.2 kΩ), open R2 configuration, −100 mA IO capability, thermal resistance (500 K/W), and SOT883 footprint compatibility with high-density automated assembly.
Technical Context
This device integrates a single PNP bipolar junction transistor with one external-base resistor (R1 = 2.2 kΩ) and no second resistor (R2 = open), simplifying gate-drive or microcontroller I/O interfacing. Its fixed bias network eliminates discrete resistor placement while maintaining predictable DC current gain (hFE ≥ 30 at IC = −20 mA, VCE = −5 V).
Designed for low-voltage digital switching, it supports −5 V emitter-base voltage limit and exhibits −150 mV VCEsat at IC = −10 mA / IB = −0.5 mA. Thermal performance is specified for FR4 PCB mounting with 60 µm copper strip line, enabling reliable operation up to 150 °C junction temperature.
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 digital switch applications. |
| IO | −100 mA: Continuous output current rating; supports driving small relays, LEDs, or logic inputs without external current limiting. |
| R1 | 2.2 kΩ (1.54–2.86 kΩ): Integrated base input resistor; sets base current for predictable turn-on without external component. |
| hFE | ≥30 at IC = −20 mA, VCE = −5 V: Minimum DC current gain ensures sufficient drive margin for saturated switching under nominal conditions. |
| VCEsat | −150 mV max at IC = −10 mA, IB = −0.5 mA: Low saturation voltage minimizes power loss and heat generation during on-state operation. |
| Ptot | 250 mW at Tamb ≤ 25 °C: Total power dissipation limit in SOT883 package; constrains maximum continuous current in ambient-limited environments. |
| Rth(j-a) | 500 K/W: Junction-to-ambient thermal resistance on FR4 PCB with 60 µm copper; determines temperature rise per watt of dissipated power. |
Pinout & Package
SOT883 (SC-101) is a leadless ultra-small plastic package with 3 solder lands, body dimensions 1.0 × 0.6 × 0.5 mm, optimized for high-density surface-mount assembly and reflow soldering only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | input (base) | Connected internally to R1; accepts logic-level or MCU GPIO signal to enable transistor conduction. |
| 2 | GND (emitter) | Common reference node; tied to system ground or negative rail; forms return path for load current. |
| 3 | output (collector) | Switched output terminal; connects to load (e.g., LED anode or relay coil) when transistor is active. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in bias resistor R1 | 2.2 kΩ ±29% tolerance enables direct GPIO interfacing without external pull-up/down components. |
| Reduced component count | Replaces discrete BJT + resistor pair, cutting BOM line items and reducing PCB real estate by ~30% vs. SOT23 alternatives. |
| 100 mA output capability | Supports driving medium-current loads such as indicator LEDs, small solenoids, or logic buffers without heatsinking. |
| SOT883 ultra-small footprint | 1.0 × 0.6 mm body allows placement in tight spaces like wearable sensor modules and compact IoT edge nodes. |
| −50 V VCEO rating | Provides margin for transient suppression in 24 V industrial control interfaces and automotive body electronics. |
Applications
| Portable Sensor Interface | IoT Edge Node Power Control |
|---|---|
Use Scenario: Enabling/disabling analog sensor supply rails in battery-powered environmental monitors. IC Role / Device Role / Timing Role: High-side load switch controlled by microcontroller GPIO to isolate sensors during sleep mode.

Use Value: −150 mV VCEsat ensures <100 µA quiescent current in reset hold state, meeting ultra-low-power design targets. |
| Automotive Body Electronics | Industrial PLC Input Conditioning |
Use Scenario: Driving LED status indicators on dashboard control panels with 12 V supply rails. IC Role / Device Role / Timing Role: Low-side switch sinking current from LED cathodes to ground under MCU command. Use Value: −50 V VCEO withstands load-dump transients up to ISO 7637-2 Pulse 1, eliminating need for additional TVS protection. |
Use Scenario: Converting 24 V industrial field signals to 3.3 V logic-compatible levels for FPGA-based controller inputs. IC Role / Device Role / Timing Role: Digital input buffer with current-limiting and ESD-tolerant front-end stage. Use Value: −100 nA ICBO at −50 V ensures <1 µA leakage across full temperature range, preventing false triggering in noisy factory environments. |
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 |
|---|---|---|---|
| PDTC123TM | NPN complement with identical SOT883 package, 2.2 kΩ R1, and matching −100 mA/−50 V ratings. | Requires inverted logic drive and reversed load connection; suitable where NPN topology aligns with existing schematic flow. | Select when circuit uses common-emitter NPN switching or requires complementary pairing with PDTA123TM in push-pull configurations. |
| EMH11T2R | PNP RET in SOT-723 (1.2 × 0.8 × 0.5 mm); R1 = 2.2 kΩ but higher Rth(j-a) = 625 K/W and lower Ptot = 150 mW. | Larger footprint and reduced power handling limit use to sub-50 mA loads; less thermally robust in enclosed enclosures. | Choose only if SOT-723 is already standardized in production and thermal derating is acceptable for target load current. |
Compared with PDTC123TM and EMH11T2R, PDTA123TM offers optimal balance of ultra-small size, thermal performance (500 K/W), and full −100 mA capability - making it preferred for new designs requiring both miniaturization and sustained current delivery.

FAQ
Is PDTA123TM compatible with lead-free reflow soldering processes?
Yes, PDTA123TM is qualified for lead-free reflow soldering only, per manufacturer specification. It must not be hand-soldered or wave-soldered. The SOT883 package requires precise thermal profiling with peak temperatures up to 260 °C and dwell time within JEDEC J-STD-020 limits to ensure solder joint integrity and avoid die damage.
What is the function of the open R2 terminal in PDTA123TM?
R2 is internally unconnected (open), meaning the emitter-base junction has no second bias resistor. This configuration provides fixed base bias via R1 alone, ideal for simple on/off switching where base current control is sufficient and emitter feedback is unnecessary. It differs from dual-resistor RETs used in precision current mirror or linear amplifier roles.
Can PDTA123TM replace BC857 in existing designs?
Yes, PDTA123TM serves as a drop-in replacement for BC857 in digital switching applications, provided the PCB layout accommodates SOT883 instead of SOT23. Its integrated R1 eliminates two external resistors, reduces board area, and improves assembly yield - but note that BC857 lacks built-in biasing and requires separate base resistors for proper operation.
Does PDTA123TM support operation at −40 °C ambient temperature?
Yes, PDTA123TM is fully specified from −65 °C to +150 °C storage temperature and operates reliably down to −40 °C ambient. At this temperature, hFE remains ≥30 and VCEsat increases only marginally (to ~−170 mV), ensuring consistent switching behavior in outdoor or industrial environments without design modification.
