Product details
Overview
PDTB123ET from Nexperia is a 500 mA, 50 V PNP resistor-equipped transistor (RET) in SOT23 package, featuring integrated bias resistors R1 = R2 = 2.2 kΩ with ±10 % ratio tolerance. It functions as a single-stage digital switch for IC input control and load switching in automotive and industrial systems, delivering VCE(sat) ≤ −0.3 V at IC = −50 mA / IB = −2.5 mA.
For engineers reviewing the PDTB123ET datasheet, PDTB123ET pinout, PDTB123ET application, or PDTB123ET equivalent, this AEC-Q101-qualified discrete device offers verified DC current gain (hFE ≥ 40), off-state input voltage (VI(off) = −0.6 to −1.8 V), and thermal resistance (Rth(j-a) = 500 K/W) for robust digital switching design.
Technical Context
This PNP RET integrates two precision-matched 2.2 kΩ bias resistors (R1 = input resistor, R2 = base-emitter feedback resistor) to eliminate external components and ensure stable turn-on/turn-off behavior. Its fixed R2/R1 ratio of 1.0 ± 0.1 enables predictable base current sourcing without manual resistor selection.
The device operates with VCEO = −50 V and IO = −500 mA, supporting high-side switching in 12 V and 24 V automotive subsystems. Its AEC-Q101 qualification confirms reliability under temperature cycling (−40 °C to +150 °C), humidity, and mechanical stress per automotive standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum collector-emitter blocking voltage in open-base configuration, enabling use in 24 V automotive power rails. |
| IO | −500 mA - Continuous output current rating, sufficient for driving relays, LEDs, and logic inputs without external heat sinking. |
| R1 | 2.2 kΩ (1.54–2.86 kΩ) - Input bias resistor sets base drive level; tolerance ensures consistent switching thresholds across production lots. |
| R2/R1 | 1.0 ± 0.1 - Matched resistor ratio guarantees stable hFE-independent biasing and reduces sensitivity to transistor gain variation. |
| VCE(sat) | ≤ −0.3 V @ IC = −50 mA - Low saturation voltage minimizes power loss and self-heating during active conduction. |
| VI(on) | −1.0 to −2.0 V @ VCE = −0.3 V - Validated on-state input voltage range ensures reliable activation from standard CMOS/TTL logic outputs. |
| Tj(max) | +150 °C - Maximum junction temperature supports operation in engine bay and under-hood environments. |
Pinout & Package
Package: SOT23 plastic surface-mounted package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch), optimized for automated placement and reflow soldering on FR4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected to internal R1; accepts logic-level control signal and sources base current through R1–R2 network. |
| 2 | Ground (emitter) | Emitter terminal tied to system ground; serves as common return path for load current and bias network. |
| 3 | Output (collector) | High-side switched output node; connects to load (e.g., relay coil or LED anode) referenced to positive rail. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity, and mechanical shock testing. |
| Integrated R1 + R2 bias network | Eliminates two external resistors, reducing BOM count and PCB area while improving assembly yield. |
| ±10 % R2/R1 ratio tolerance | Ensures consistent switching characteristics across temperature and process variation without calibration. |
| 250 mW power dissipation (Tamb ≤ 25 °C) | Enables operation without heatsinking in ambient temperatures up to +85 °C with derating. |
| Low VI(off) (−0.6 to −1.8 V) | Guarantees full cutoff with standard 0 V logic low, preventing leakage-induced false triggering. |
Applications
| Automotive Body Control Module | Industrial PLC Digital Output |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP digital switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTB114ET | R1 = 10 kΩ, R2 = 10 kΩ; lower IO = −100 mA; hFE ≥ 35 | Suitable only for low-current logic buffering, not 500 mA loads | Select when driving <10 mA loads and higher input impedance is required. |
| BC807-40 | Standard PNP BJT (no built-in resistors); requires external RB; VCEO = −45 V; IC = −500 mA | Needs two external resistors; less compact; no AEC-Q101 qualification | Choose only if resistor customization or legacy BC807 footprint compatibility is mandatory. |
Compared with PDTB114ET and BC807-40, the PDTB123ET uniquely delivers AEC-Q101 qualification, matched 2.2 kΩ bias network, and guaranteed −500 mA capability in SOT23-making it optimal for cost-sensitive, high-reliability automotive and industrial digital switching where board space and supply chain simplicity matter.

FAQ
Is PDTB123ET pin-compatible with BC807 series transistors?
No, PDTB123ET uses a different pinout: Pin 1 = Input (base), Pin 2 = GND (emitter), Pin 3 = Output (collector). BC807 has emitter-collector-base ordering in SOT23. Direct replacement requires PCB layout revision and bias network removal.
What is the maximum ambient temperature for continuous 500 mA operation?
At IO = −500 mA, power dissipation reaches ~150 mW (based on VCE(sat) ≈ −0.3 V). With Rth(j-a) = 500 K/W, junction temperature rise is 75 °C. Starting from Tamb = +75 °C yields Tj = 150 °C - the absolute maximum. Derating is required above +75 °C ambient.
Does PDTB123ET support 3.3 V logic-level drive?
Yes. VI(on) ranges from −1.0 V to −2.0 V at VCE = −0.3 V, meaning a 3.3 V logic high (0 V referenced) fully satisfies the turn-on threshold. The integrated R1 ensures adequate base current even with 3.3 V drive and typical MCU output impedance.
How does the R2/R1 ratio affect switching performance?
An R2/R1 ratio of 1.0 ± 0.1 stabilizes the effective base current against hFE variation, ensuring consistent VCE(sat) and switching speed across production lots and temperature. Deviations beyond ±10 % risk incomplete saturation or excessive base current consumption.
