Product details
Overview
PDTB123YT from Nexperia is a PNP resistor-equipped transistor (RET) in SOT23 package, designed for digital switching with −50 V VCEO, −500 mA IO, built-in R1 = 2.2 kΩ and R2/R1 = 4.55 ratio, used in automotive and industrial load control circuits.
For engineers reviewing the PDTB123YT datasheet, PDTB123YT pinout, PDTB123YT application, or PDTB123YT equivalent, key selection criteria include guaranteed −500 mA output current capability, ±10 % R2/R1 tolerance, −300 mV VCEsat at −50 mA, VI(on) range of −0.5 to −1.4 V, and SOT23 thermal resistance of 500 K/W.
Technical Context
This PNP RET integrates base biasing network (R1 = 2.2 kΩ, R2 = 10 kΩ) to eliminate external resistors, enabling direct logic-level drive without discrete bias components. It operates with VEB up to −5 V and supports input voltage ranges from −0.4 V (VI(off)) to −1.4 V (VI(on)) at 25 °C.
The device delivers stable DC current gain (hFE ≥ 70 at −50 mA/−5 V) across −40 °C to +100 °C, with collector capacitance of 11 pF at −10 V and 100 MHz, and maintains ≤ −0.5 µA ICEO cutoff under −50 V VCE.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - maximum safe collector-emitter voltage with open base |
| IO | −500 mA - continuous output current rating for load switching |
| R1 | 2.2 kΩ - integrated input bias resistor enabling direct microcontroller interface |
| R2/R1 | 4.55 - precise internal resistor ratio ensuring consistent turn-on behavior |
| VCEsat | −300 mV - low saturation voltage at −50 mA/−2.5 mA drive, minimizing power loss |
| Ptot | 250 mW - total power dissipation on FR4 PCB, defining thermal derating envelope |
| Cc | 11 pF - collector capacitance limiting high-frequency switching speed |

Applications
| Automotive Lighting Control | Industrial PLC Input Buffer |
|---|---|
Use Scenario: Switching 12 V LED arrays in cabin lighting modules using 3.3 V MCU GPIO. IC Role / Device Role / Timing Role: PNP RET acts as level-shifting high-side switch, sinking current from LED anode to ground. Use Value: Built-in R1/R2 eliminates need for external biasing, reducing component count by 2 and layout complexity. | Use Scenario: Conditioning 24 V digital inputs from field sensors into 5 V logic levels for PLC controller. IC Role / Device Role / Timing Role: Functions as active-low input buffer with defined VI(off) threshold (≤ −0.4 V) to reject noise. Use Value: Guaranteed R2/R1 ratio ensures consistent hysteresis margin between on/off states across temperature. |
| Consumer Appliance Motor Driver | IoT Sensor Power Gate |
Use Scenario: Enabling/disabling small DC motors in smart home appliances via microcontroller PWM. IC Role / Device Role / Timing Role: Serves as low-loss switching element with −300 mV VCEsat minimizing heat generation during duty cycling. Use Value: 250 mW Ptot rating allows sustained 500 mA operation only with proper PCB copper pour; enables compact motor control design. | Use Scenario: Power-gating peripheral sensors (e.g., temperature, humidity) in battery-powered edge nodes. IC Role / Device Role / Timing Role: Acts as load switch controlling VCC to sensor ICs, with VI(off) ≤ −0.4 V ensuring full shutdown leakage < 0.5 µA. Use Value: ICEO ≤ −0.5 µA at −50 V guarantees sub-µA quiescent current, extending battery life in sleep mode. |
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 |
|---|---|---|---|
| PDTB114YT | R1 = 10 kΩ, R2/R1 = 4.55, lower IO (−100 mA) | Optimized for low-current logic interfacing, not load switching | Select when driving high-impedance inputs rather than 500 mA loads |
| BC807-40 | Discrete PNP BJT, no integrated resistors; requires external bias network | Higher design flexibility but increases BOM count and layout area | Choose when precise custom biasing or higher hFE (>250) is required |
Compared with PDTB114YT, PDTB123YT delivers five times higher output current for load switching; compared with BC807-40, it reduces PCB footprint and assembly cost by integrating both bias resistors while maintaining compatible SOT23 mounting.

FAQ
What is the maximum continuous collector current for PDTB123YT?
The PDTB123YT is rated for −500 mA continuous output current under Tamb ≤ 25 °C with adequate PCB copper area. Derating is required above 25 °C ambient per its 500 K/W thermal resistance; at 70 °C ambient, maximum sustainable current drops to approximately −300 mA on standard FR4.
Can PDTB123YT replace BC807-40 in existing designs?
PDTB123YT can replace BC807-40 in digital switching applications where the BC807 uses external 2.2 kΩ and 10 kΩ base resistors. Pin compatibility (SOT23, same pinout) and matching VCEO/IO ratings enable drop-in substitution, but VI(on)/VI(off) thresholds differ due to integrated bias network-verify logic-level compatibility before redesign.
What is the significance of R₂/R₁ = 4.55 in PDTB123YT?
The fixed R2/R1 ratio of 4.55 sets the internal feedback network that defines the transistor's turn-on sensitivity and noise immunity. It ensures VI(on) remains within −0.5 V to −1.4 V and VI(off) stays ≤ −0.4 V across temperature, providing repeatable switching thresholds without external tuning.
Is PDTB123YT qualified for automotive applications?
No-PDTB123YT is explicitly marked as non-automotive qualified in its revision history (v.5, Jan 2023). It lacks AEC-Q101 qualification, automotive-grade screening, and extended temperature validation beyond −40 °C to +100 °C. For automotive use, select the -Q qualified variant (e.g., PDTB123YTX).
