Product details
Overview
PDTA124ET-QVL from Nexperia is a PNP resistor-equipped transistor (RET) in SOT23 package, designed for digital switching in automotive and industrial systems. It features 50 V VCEO, 100 mA output current capability, built-in R1 = 22 kΩ and R2 = 22 kΩ bias resistors, and AEC-Q101 qualification - enabling direct interface with microcontroller GPIOs to drive small loads such as LEDs or logic inputs.
For engineers reviewing the PDTA124ET-QVL datasheet, PDTA124ET-QVL pinout, PDTA124ET-QVL application, or PDTA124ET-QVL equivalent, key selection factors include its integrated bias network, guaranteed -50 V collector-emitter breakdown, -150 mV VCE(sat) at IC = -10 mA, and thermal resistance of 500 K/W on FR4 PCB - critical for reliable operation in space-constrained automotive modules.
Technical Context
This RET integrates a PNP bipolar transistor with two precision silicon-based bias resistors (R1 = 22 kΩ ±30%, R2/R1 = 1.0 ±20%) to form a single-input, single-output digital switch. Its internal structure eliminates external base resistors while maintaining predictable turn-on/off thresholds across temperature (-40 °C to +150 °C).
The device operates with VI(on) = -2.5 V to -1.7 V at IC = -5 mA and VI(off) = -1.1 V to -0.8 V at IC = -100 µA, ensuring robust noise immunity in 3.3 V/5 V logic environments. Its fT = 180 MHz (typ.) supports fast edge transitions, and Cc = 3 pF (max.) minimizes capacitive loading on driving sources.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -50 V - Maximum safe voltage between collector and emitter with base open; defines load-side voltage headroom in high-side switching. |
| IO | -100 mA - Continuous DC output current capability; sufficient for driving LEDs, relays, or logic inputs without external current limiting. |
| R1 | 22 kΩ (15.4–28.6 kΩ) - Input bias resistor sets base current; enables direct connection to MCU GPIO without discrete resistor. |
| VCE(sat) | -150 mV (max) at IC = -10 mA, IB = -0.5 mA - Low saturation voltage reduces power loss and heat generation during on-state operation. |
| hFE | 60 (min) at VCE = -5 V, IC = -5 mA - Guaranteed current gain ensures stable switching behavior even under worst-case process and temperature conditions. |
| Ptot | 250 mW at Tamb ≤ 25 °C - Total power dissipation limit on standard FR4 PCB; derates linearly above 25 °C per Fig. 1. |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive discrete semiconductors; supports use in engine control, body electronics, and ADAS modules. |
Pinout & Package
SOT23 plastic surface-mounted package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pitch), optimized for automated placement and reflow soldering on FR4 PCBs with 35 µm tin-plated copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level input voltage to enable transistor conduction. |
| 2 | Ground (emitter) | Common reference node; connects to system ground or low-side return path in high-side switch configurations. |
| 3 | Output (collector) | Switched output terminal; sinks current from load connected between VCC and pin 3 when active. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Eliminates need for two external resistors, reducing BOM count and PCB area by ~2.5 mm² per instance. |
| Automotive-grade qualification | AEC-Q101 qualified for temperature cycling, HTRB, and ESD testing - supports Tier-1 supply chain compliance. |
| Low VCE(sat) | -150 mV max ensures <1.5 mW conduction loss at 10 mA, minimizing self-heating in thermally constrained modules. |
| Wide operating temperature | -65 °C to +150 °C ambient range enables deployment in under-hood and battery management applications. |
| Standard SOT23 footprint | Compatible with existing pick-and-place equipment and reflow profiles used for BC847-series transistors. |
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 |
|---|---|---|---|
| PDTC124ET-Q | NPN complement with identical R1/R2 values and AEC-Q101 rating; requires inverted logic drive and low-side load configuration. | Used where load must be connected to VCC and switched to ground - e.g., N-channel MOSFET gate drivers. | Select when circuit topology favors low-side switching or when matching NPN/PNP pairs is required for balanced design. |
| BC807-40 | Discrete PNP transistor without bias resistors; requires external RB and offers higher hFE (250 min) but no integrated logic interface. | Suitable for analog amplification or high-gain switching where precise base current control is needed beyond digital on/off. | Choose only if external biasing is acceptable and higher DC gain or lower VCE(sat) (<100 mV) is mandatory. |
Compared with PDTC124ET-Q, PDTA124ET-QVL provides native high-side switching with non-inverted logic compatibility; versus BC807-40, it trades off gain and saturation voltage for reduced component count and AEC-Q101 assurance in automotive digital I/O.

FAQ
What is the maximum allowable input voltage at Pin 1?
The absolute maximum input voltage at Pin 1 (I) is -40 V, as specified in Table 5 (Limiting Values). Operation above this level risks permanent damage to the internal bias resistors or transistor junction. For reliable 3.3 V or 5 V logic interfacing, VI(on) and VI(off) thresholds ensure proper switching within -2.5 V to -0.8 V range.
Can PDTA124ET-QVL replace BC847 in existing designs?
Yes - as a drop-in replacement in digital switching roles, provided the BC847 is used in common-emitter configuration with external base resistors. The RET's integrated R1/R2 simplifies layout and improves consistency, but note the PNP polarity and -50 V VCEO differ from BC847's NPN -45 V rating.
Is thermal derating required for continuous 100 mA operation?
Yes - at ambient temperatures above 25 °C, power dissipation must be derated per Fig. 1. At 85 °C ambient, maximum allowed Ptot drops to ~150 mW, limiting sustainable IO to approximately -77 mA at VCE(sat) = -150 mV. Forced airflow or copper pour can improve thermal performance.
Does the QVL suffix indicate a different specification than Q?
No - the "QVL" suffix denotes tape-and-reel packaging with lead-free, RoHS-compliant finish and AEC-Q101 qualification identical to the base "Q" version. Electrical, thermal, and reliability specifications remain unchanged per the 8 September 2025 product data sheet.
