Product details
Overview
PDTA123YT from Nexperia is a PNP resistor-equipped transistor (RET) designed for general-purpose switching and amplification in compact surface-mount applications. It integrates two precision bias resistors (R1 = 2.2 kΩ, R2/R1 = 4.5 typ), delivers −100 mA DC output current, supports −50 V collector-emitter voltage, and uses the SOT23 (TO-236AB) package for space-constrained PCB layouts - commonly deployed in logic-level interface circuits and low-power load switching.
For engineers reviewing the PDTA123YT datasheet, PDTA123YT pinout, PDTA123YT application, or PDTA123YT equivalent, key selection criteria include its built-in resistor ratio (3.6–5.5), guaranteed −150 mV VCEsat at −10 mA/−0.5 mA drive, off-state input voltage range (−0.75 to −0.3 V), thermal resistance (500 K/W), and compatibility with reflow-only soldering per JEDEC J-STD-020.
Technical Context
This device implements a monolithic PNP bipolar junction transistor with integrated R1 (base-input resistor) and R2 (base-emitter feedback resistor), eliminating external bias components. Its fixed R2/R1 ratio of 4.5 typ enables predictable turn-on behavior without base current calculation.
The SOT23 package defines its thermal performance (Rth(j-a) = 500 K/W) and maximum power dissipation (250 mW at Tamb ≤ 25 °C). Electrical operation is specified across −40 °C to +150 °C junction temperature, with VI(off) and VI(on) thresholds optimized for TTL/CMOS-compatible digital driving.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum safe collector-emitter voltage under open-base conditions; defines breakdown margin in switching applications. |
| IO (DC) | −100 mA: Continuous collector current capability; sets upper limit for load-driving capacity in DC switch designs. |
| R1 | 2.2 kΩ (typ): Input bias resistor value; determines required drive current for reliable saturation at defined VCEsat. |
| R2/R1 | 4.5 (typ): Fixed feedback-to-input resistor ratio; ensures stable current gain and reduces sensitivity to hFE variation. |
| VCEsat | −150 mV (max at IC = −10 mA, IB = −0.5 mA): Low saturation voltage minimizes conduction loss and self-heating in high-duty-cycle switches. |
| VI(on) | −1.15 V (typ at IC = −20 mA): On-state input voltage threshold; confirms compatibility with standard 3.3 V and 5 V logic outputs. |
| VI(off) | −0.75 V (typ at IC = −100 µA): Off-state input voltage upper bound; guarantees cutoff when driven by low-voltage logic high levels. |
Pinout & Package
The PDTA123YT uses the SOT23 (TO-236AB) plastic surface-mounted package - a 3-lead, 1.3 mm × 2.9 mm × 1.0 mm outline with gull-wing leads, optimized for automated placement and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | input (base) | Connected internally to R1; accepts logic-level drive signal and routes current through R1 to base node. |
| 2 | GND (emitter) | Emitter terminal tied to system ground reference; serves as common return path for load current and bias network. |
| 3 | output (collector) | High-side switching node; sinks load current from VCC through external load to emitter (pin 2). |
Key Features
| Feature | Design Value |
|---|---|
| Built-in bias resistors R1 and R2 | Eliminates need for two external resistors, reducing BOM count and PCB area in discrete switch designs. |
| Guaranteed R2/R1 ratio | 3.6–5.5 range ensures consistent turn-on characteristics across production lots, easing design validation. |
| Low VCEsat at rated current | −150 mV max at −10 mA enables <15 mW conduction loss, supporting thermally constrained environments. |
| Reflow-solder compatible | Qualified per JEDEC J-STD-020; supports lead-free assembly without derating or special process controls. |
| Wide operating temperature | Junction range −40 °C to +150 °C allows deployment in automotive cabin modules and industrial control enclosures. |
Applications
| LED Driver Circuit | Microcontroller GPIO Expander |
|---|---|
Use Scenario: Driving 20 mA indicator LEDs from 3.3 V microcontroller I/O pins with no external resistors. IC Role / Device Role: Single-transistor high-side switch with integrated base bias network. Use Value: Reduces component count by two resistors per channel and eliminates manual resistor selection errors. |
Use Scenario: Adding 8-bit parallel output capability to an MCU with limited GPIOs using discrete logic-level translation. IC Role / Device Role: Level-shifting buffer for 3.3 V logic signals controlling 5 V peripheral enable lines. Use Value: Ensures clean 5 V-compatible switching without additional level translators or pull-up networks. |
| Power Rail Sequencing | Industrial Sensor Interface |
Use Scenario: Enabling auxiliary 3.3 V rail only after main 5 V supply stabilizes, using comparator output as control signal. IC Role / Device Role: Controlled power switch activated by comparator's open-collector output. Use Value: Provides deterministic turn-on delay via VI(on) threshold and avoids latch-up risk from floating inputs. |
Use Scenario: Isolating analog sensor output (e.g., thermistor divider) from noisy digital subsystems using active guarding. IC Role / Device Role: Low-leakage switch enabling/disabling sensor bias current on demand. Use Value: ICEO ≤ −1 µA prevents measurement drift during sleep mode; −50 V VCEO withstands transient coupling. |
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 |
|---|---|---|---|
| PDTC123YT | NPN complement with identical R1/R2 values and SOT23 package; requires inverted logic drive. | Suitable where load is connected to ground and switching occurs on high-side (VCC path). | Select when circuit topology demands NPN configuration or existing layout uses NPN RETs. |
| NSV123YTR | Automotive-grade AEC-Q101 qualified version; same R1/R2, but tighter VI(on)/VI(off) tolerances and extended temp range. | Required for under-hood automotive modules where reliability and qualification compliance are mandatory. | Choose for automotive applications needing certified stress testing and failure rate data. |
Compared with PDTC123YT, PDTA123YT provides complementary polarity for high-side switching without redesigning gate drive logic; versus NSV123YTR, it offers cost-optimized industrial performance without AEC-Q101 overhead, making it ideal for consumer and computing applications.

FAQ
What is the maximum continuous collector current for PDTA123YT?
The PDTA123YT supports −100 mA DC output current (IO) under standard ambient conditions (Tamb ≤ 25 °C). Derating applies above 25 °C per the thermal resistance of 500 K/W; at 70 °C ambient, maximum usable current drops to approximately −55 mA to maintain Tj ≤ 150 °C.
Can PDTA123YT be used with 1.8 V logic inputs?
No - the VI(on) specification requires ≥ −1.15 V (typ) at −20 mA load to ensure reliable turn-on. A 1.8 V logic high translates to only −1.8 V at the base input relative to emitter (pin 2), which falls within the guaranteed VI(on) range; however, VI(off) upper limit is −0.3 V, so 1.8 V logic may not fully cut off the device. Use ≥ 3.3 V logic for assured operation.
Is reflow soldering the only recommended assembly method?
Yes - the datasheet explicitly states "Reflow soldering is the only recommended soldering method" for PDTA123YT. Wave or hand soldering is not qualified and risks thermal damage due to the SOT23 package's low thermal mass and internal resistor tolerances.
How does the built-in R2 resistor affect switching speed?
The R2 resistor (10 kΩ typ) provides base-emitter feedback that improves turn-off speed by actively discharging base charge. Measured turn-off time (tf) is typically 120 ns at IC = −50 mA, significantly faster than discrete PNP configurations without intentional base discharge paths.
