Product details
Overview
PDTB123TT from Nexperia is a 500 mA, −50 V PNP resistor-equipped transistor (RET) in SOT23 package, featuring a built-in 2.2 kΩ input bias resistor and open R2 terminal. It functions as a digital switch for IC input control and load switching in automotive and industrial systems, with AEC-Q101 qualification and −65 °C to +150 °C operating range.
For engineers reviewing the PDTB123TT datasheet, PDTB123TT pinout, PDTB123TT application, or PDTB123TT equivalent, key selection criteria include its PNP RET topology, −500 mA output capability, integrated R1 bias network, SOT23 footprint compatibility, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This PNP RET integrates a single 2.2 kΩ base-input resistor (R1) with R2 left unconnected, enabling direct logic-level drive without external bias components. Its DC current gain (hFE) ranges from 100 to 250 at −50 mA collector current and −5 V VCE.
It delivers −0.3 V typical VCE(sat) at −50 mA/−2.5 mA drive, supports −50 V VCEO, and exhibits −100 nA ICBO at −40 V VCB. Thermal resistance is 500 K/W junction-to-ambient on FR4 PCB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum safe collector-emitter voltage with open base, defining high-side switching headroom. |
| IO | −500 mA: Continuous output current rating, supporting medium-power digital load switching. |
| R1 | 2.2 kΩ (1.54–2.86 kΩ): Integrated base-input resistor enabling direct microcontroller GPIO drive without external bias. |
| hFE | 100–250: DC current gain at −5 V VCE, −50 mA IC, ensuring predictable saturation under standard logic drive. |
| VCE(sat) | −0.3 V typ. at −50 mA IC/−2.5 mA IB: Low saturation voltage minimizes power loss in switching applications. |
| Ptot | 250 mW at Tamb ≤ 25 °C: Power dissipation limit on standard FR4 PCB, guiding thermal layout decisions. |
Pinout & Package
Package: SOT23 (TO-236AB), 3-lead surface-mount plastic package with 0.95 mm pitch, 2.8 mm × 1.4 mm footprint, and 1.1 mm height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1 (2.2 kΩ); accepts logic-level drive directly from MCU or gate output. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; serves as common return path for switched loads. |
| 3 | Output (collector) | Switched high-side output node; connects to load anode when used in low-side configuration or load cathode in high-side. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 bias resistor | Eliminates need for external base resistor, reducing BOM count and PCB area in digital switching circuits. |
| AEC-Q101 qualification | Validated for automotive applications including engine control modules and body electronics requiring robustness to temperature cycling and vibration. |
| −500 mA output rating | Supports driving relays, LEDs, small solenoids, and logic inputs without additional amplification stages. |
| SOT23 footprint compatibility | Enables drop-in replacement of BC807 series transistors while reducing assembly cost via simplified pick-and-place programming. |
Applications
| Automotive Body Control Module | Industrial PLC Digital Output |

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 |
|---|---|---|---|
| BC807-40 | Discrete PNP BJT without integrated resistors; requires external base bias network. | Higher design flexibility but increases component count and layout complexity. | Select when precise hFE tuning or variable bias is required beyond fixed R1 value. |
| PDTB123ET,215 | Same RET architecture but in SC-70 (SOT323) package; smaller footprint, higher thermal resistance (625 K/W). | Preferred for space-constrained portable designs where 250 mW derating is acceptable. | Select when board area is critical and ambient temperature remains below 70 °C. |
Compared with BC807-40 and PDTB123ET,215, PDTB123TT offers optimal balance of integrated biasing, SOT23 manufacturability, and thermal performance for automotive and industrial digital switching-delivering lower assembly cost without sacrificing reliability or electrical margin.

FAQ
Is PDTB123TT pin-compatible with BC807-40?
No. PDTB123TT has base-input (pin 1), emitter-GND (pin 2), and collector-output (pin 3). BC807-40 uses emitter-base-collector pinout (1–2–3), making them electrically incompatible without PCB redesign. The RET integrates R1 internally, eliminating the need for external bias components that BC807 requires.
What is the maximum allowable input voltage at pin 1?
The absolute maximum input voltage at pin 1 (base) is −12 V for negative transients and +5 V for positive transients, per limiting values table. Exceeding these risks permanent damage to the internal R1 resistor or junction. For standard 3.3 V or 5 V logic drive, no clamping is needed due to built-in VI limits.
Can PDTB123TT be used in high-frequency switching applications?
No. With a typical collector capacitance of 11 pF and no specified fT or switching time data, PDTB123TT is optimized for DC and low-frequency digital switching (≤100 kHz). Its design prioritizes saturation performance and bias integration-not RF or fast PWM operation.
Does PDTB123TT support reverse polarity protection?
No. As a PNP RET, it conducts when base is pulled low relative to emitter. It does not provide inherent reverse-polarity protection. External diodes or dedicated protection ICs are required for systems exposed to battery reversal or incorrect connector mating.
