Product details
Overview
PDTC124ET-QVL from Nexperia is an AEC-Q101-qualified NPN resistor-equipped transistor (RET) in SOT23 package, featuring integrated 22 kΩ base bias resistors (R1 = R2 = 22 kΩ), 50 V VCEO, 100 mA IO, and optimized for automotive digital switching applications such as IC input control and load switching.
For engineers reviewing the PDTC124ET-QVL datasheet, PDTC124ET-QVL pinout, PDTC124ET-QVL application, or PDTC124ET-QVL equivalent, this part serves as a drop-in, space-saving replacement for BC847-based digital interface circuits-especially where board area, BOM count, and AEC-Q101 compliance are critical.
Technical Context
This RET integrates two precision-matched 22 kΩ bias resistors to configure the base drive network internally, eliminating external resistors and enabling direct logic-level control. Its R2/R1 ratio of 1.0 ±20% ensures stable saturation behavior across temperature.
The device operates with VI(on) = 1.7–2.5 V at IC = 5 mA and VI(off) = 0.8–1.1 V at IC = 100 µA, supporting clean TTL/CMOS-compatible switching. Its fT = 230 MHz (typ.) reflects the high-speed capability of the underlying NPN die.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports 24 V automotive rail switching with margin. |
| IO | 100 mA - Continuous output current rating; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 / R2 | 22 kΩ / 22 kΩ - Integrated base bias resistors; eliminates two external components and reduces layout complexity. |
| VCE(sat) | ≤100 mV at IC = 10 mA, IB = 0.5 mA - Low saturation voltage minimizes power loss and heat generation in on-state. |
| hFE | ≥60 at VCE = 5 V, IC = 5 mA - Guaranteed DC current gain ensures reliable turn-on under worst-case conditions. |
| fT | 230 MHz - Transition frequency of internal transistor; enables fast edge response in digital switching. |
| Ptot | 250 mW at Tamb ≤ 25 °C - Thermal limit defines maximum dissipation on standard FR4 PCB without heatsinking. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body; optimized for automated placement and reflow soldering on standard FR4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Logic-level signal entry point; connected internally to R1 and R2 network for self-biasing. |
| 2 | GND (emitter) | Emitter tied to ground reference; provides return path for both bias and output currents. |
| 3 | Output (collector) | Switched high-side output node; connects to load (e.g., LED anode or relay coil) referenced to VCC. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias resistors | Eliminates need for two external 22 kΩ resistors-reducing BOM count, PCB area, and assembly cost. |
| AEC-Q101 qualification | Validated for automotive environments per stress test requirements including HTGB, HTRB, and ESD-HBM ≥2 kV. |
| Low VI(on)/VI(off) thresholds | Enables robust switching with 3.3 V or 5 V logic families without level-shifting circuitry. |
| Thermal resistance Rth(j-a) | 500 K/W on standard FR4 PCB-supports operation up to +125 °C ambient in engine bay modules. |
| Matched R2/R1 ratio | 1.0 ±20% tolerance ensures consistent saturation characteristics across production lots and temperature. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847B,115 | Discrete NPN transistor requiring external 22 kΩ base resistors; no integrated bias network. | Higher BOM count and layout area; lacks AEC-Q101 qualification out-of-box. | Select when legacy designs require pin-for-pin compatibility with existing BC847 footprints and qualification is handled externally. |
| PDTA124ET-QVL | PNP complement with identical R1/R2 values (22 kΩ), same SOT23 package, and AEC-Q101 rating. | Used for high-side switching or complementary logic configurations-not direct functional replacement. | Select when designing push-pull or dual-rail digital interfaces requiring matched NPN/PNP RET pairs. |
Compared with BC847B,115, PDTC124ET-QVL reduces design effort and validation scope by integrating biasing; compared with PDTA124ET-QVL, it delivers NPN polarity essential for low-side switching topologies.

FAQ
What is the maximum operating temperature for PDTC124ET-QVL?
The junction temperature (Tj) must not exceed 150 °C, and ambient temperature (Tamb) is rated from −65 °C to +150 °C. Derating begins above 25 °C ambient per the 500 K/W thermal resistance curve-e.g., at 85 °C ambient, max Ptot drops to ~150 mW on standard FR4 PCB.
Can PDTC124ET-QVL replace BC847 in existing designs without layout changes?
No-PDTC124ET-QVL uses SOT23 pinout (1=Input, 2=GND, 3=Output), whereas BC847 in SOT23 has 1=E, 2=B, 3=C. Direct replacement requires PCB revision to match pin mapping and remove external bias resistors.
Is the R1/R2 ratio truly 1:1, and how tightly is it controlled?
Yes-the R2/R1 ratio is specified as 0.8 to 1.2 (±20%) under test conditions, with typical value of 1.0. This tight matching ensures consistent VCE(sat) and switching thresholds across temperature and process variation.
Does PDTC124ET-QVL support PWM-driven loads?
Yes-its 230 MHz fT and sub-100 ns switching times (typ.) support PWM frequencies up to several MHz. However, thermal limits (250 mW Ptot) constrain average power; for >10 kHz PWM at full 100 mA, verify junction temperature rise with actual duty cycle and PCB copper area.
