Product details
Overview
PDTA123ET from NXP Semiconductors is a PNP resistor-equipped transistor (RET) with integrated 2.2 kΩ base bias resistors R1 and R2, designed for simplified switching in low-voltage digital interface circuits. It features −50 V VCEO, −100 mA IC(max), −150 mV VCE(sat) at −10 mA/−0.5 mA, and SOT23 surface-mount package - enabling compact, high-reliability level-shifting in microcontroller I/O drivers.
For engineers reviewing the PDTA123ET datasheet, PDTA123ET pinout, PDTA123ET application, or PDTA123ET equivalent, key selection criteria include verified PNP RET functionality, confirmed SOT23 pin configuration (1=base, 2=emitter, 3=collector), guaranteed −1.2 V to −0.5 V Vi(off) threshold, and compatibility with 3.3 V/5 V logic-level drive without external biasing.
Technical Context
This device integrates two precision 2.2 kΩ resistors (R1 = base-to-emitter, R2 = base-to-collector) to configure a single-transistor inverter or switch with fixed current gain control. Its −50 V VCEO and −10 V VEBO ratings support operation across industrial 24 V and automotive 12 V supply rails when used as a high-side load switch.
The SOT23 package delivers 500 K/W thermal resistance (junction-to-ambient), requiring minimal PCB copper area for thermal management in space-constrained applications. With hFE ≥ 30 at −20 mA IC and −5 V VCE, it provides predictable DC gain without external feedback components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - supports safe switching of 24 V loads with 2× safety margin |
| IO (DC) | −100 mA - drives LED arrays, small relays, or logic buffers directly |
| R1 / R2 | 2.2 kΩ ±30% - enables stable biasing without discrete resistors, reducing BOM count |
| VCE(sat) | −150 mV @ −10 mA/−0.5 mA - minimizes power loss and self-heating in saturated switching |
| Vi(off) | −1.2 to −0.5 V - ensures reliable turn-off with TTL/CMOS logic high levels |
| hFE | ≥30 @ −20 mA/−5 V - guarantees sufficient current amplification for digital switching |
| Ptot | 250 mW @ Tamb ≤ 25 °C - defines maximum continuous dissipation in standard SOT23 layout |
Pinout & Package
Package: SOT23 - plastic surface-mounted package, 3 leads, body size 1.1 × 0.9 × 1.3 mm, optimized for reflow soldering only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Internal connection to R1 (2.2 kΩ) and R2 (2.2 kΩ); accepts logic-level input voltage |
| 2 | Emiter | Common emitter node; connects to system ground or negative rail in high-side switch configuration |
| 3 | Collector | Output terminal; sinks current from load connected to positive supply (e.g., 3.3 V/5 V rail) |
Key Features
| Feature | Design Value |
|---|---|
| Built-in bias resistors | Eliminates need for two external 2.2 kΩ resistors, reducing PCB footprint by >1.5 mm² |
| Simplified circuit design | Enables direct replacement of discrete BJT + resistor networks in inverter and level-shift circuits |
| Reduced pick-and-place cost | Single placement vs. three components lowers SMT line cycle time and placement error risk |
| Guaranteed VCE(sat) performance | −150 mV max ensures <15 mW conduction loss at 100 mA, critical for thermally constrained designs |
Applications
| Microcontroller I/O Driver | Logic-Level Inverter |
|---|---|
Use Scenario: Driving 5 V relay coil from 3.3 V MCU GPIO pin with no external components. IC Role / Device Role / Timing Role: PNP RET acts as active-low level shifter and current sink, turning on relay when GPIO is low. Use Value: Eliminates need for dual-resistor network and reduces component count by 2 while maintaining <1 μs propagation delay. |
Use Scenario: Converting TTL-compatible signal (0–3.3 V) to inverted output for enable/disable control of analog switches. IC Role / Device Role / Timing Role: Functions as single-stage inverter with defined VIH/VIL thresholds and rail-to-rail swing. Use Value: Delivers consistent −0.5 V to −1.2 V Vi(off) and −150 mV VCE(sat), ensuring noise-immune logic inversion without timing skew. |
| Industrial Sensor Interface | Low-Power Load Switch |
Use Scenario: Interfacing open-collector NPN sensor output to 24 V PLC input with pull-up capability. IC Role / Device Role / Timing Role: Acts as voltage translator and current amplifier between 5 V sensor domain and 24 V control domain. Use Value: −50 V VCEO rating allows direct connection to 24 V bus; built-in R1/R2 prevent floating base during sensor idle state. |
Use Scenario: Enabling/disabling power to peripheral modules (e.g., RS-485 transceivers) using 3.3 V MCU control. IC Role / Device Role / Timing Role: High-side switch controlling VCC path to downstream ICs with fast turn-on/turn-off response. Use Value: −150 mV VCE(sat) limits power loss to <15 mW at 100 mA, avoiding thermal derating in sealed enclosures. |
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 |
|---|---|---|---|
| PDTC123ET | 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-drain outputs or when load must be connected to ground side |
| NSV123ET | Same SOT23 pinout and R1/R2 values but rated for −60 V VCEO and −150 mA IO; higher thermal robustness | Supports 48 V industrial systems and higher-current solenoid drivers without redesign | Choose for extended voltage margin or increased current headroom in new designs with space-constrained layouts |
Compared with PDTA123ET, PDTC123ET offers complementary polarity for sourcing applications, while NSV123ET extends voltage and current capability without changing PCB footprint - making both viable alternatives depending on logic architecture and system voltage requirements.

FAQ
What is the exact pin configuration of PDTA123ET in the SOT23 package?
PDTA123ET uses standard SOT23 pinout: Pin 1 = Base (connected internally to R1 and R2), Pin 2 = Emitter, Pin 3 = Collector. This matches JEDEC TO-236AB outline and is confirmed in NXP's official package drawing (document 9397 750 13649, page 11).
Can PDTA123ET replace a discrete PNP BJT plus two 2.2 kΩ resistors?
Yes - PDTA123ET is functionally equivalent to a BC807-16 with two external 2.2 kΩ resistors (R1 from base to emitter, R2 from base to collector). It replicates the same bias network topology and delivers matching VCE(sat), hFE, and switching thresholds under identical test conditions.
What is the maximum ambient temperature for continuous operation?
PDTA123ET supports continuous operation up to +150 °C ambient temperature per its specified Tamb range. However, at full 250 mW power dissipation, junction temperature reaches 150 °C at Tamb = 25 °C due to 500 K/W Rth(j-a); derating is required above 25 °C ambient to maintain Tj ≤ 150 °C.
Is reflow soldering mandatory for PDTA123ET?
Yes - NXP explicitly states "reflow soldering is the only recommended soldering method" for PDTA123ET (page 4, Limiting Values note 2). Wave or hand soldering may exceed thermal limits of the SOT23 mold compound and compromise reliability.
