Product details
Overview
PDTC124EQC-Q from Nexperia is a 50 V, 100 mA NPN resistor-equipped transistor (RET) in a DFN1412D-3 (SOT8009) leadless package with side-wettable flanks. It integrates 22 kΩ input and 22 kΩ base-emitter bias resistors, delivers 60× DC current gain at 5 mA collector current, and achieves ≤100 mV collector-emitter saturation voltage - enabling direct digital logic interfacing for load switching in automotive body control modules.
For engineers reviewing the PDTC124EQC-Q datasheet, PDTC124EQC-Q pinout, PDTC124EQC-Q application, or PDTC124EQC-Q equivalent, this device serves as an AEC-Q101-qualified, space-constrained alternative to discrete BJT + resistor solutions in 1.4 × 1.2 mm PCB footprints requiring <0.5 mm profile and AOI-compatible solder joints.
Technical Context
This RET implements a monolithic NPN silicon transistor with two integrated precision thin-film resistors: R1 (22 kΩ) between base and input terminal, and R2 (22 kΩ) between base and emitter. The 1:1 R2/R1 ratio enables predictable turn-on behavior under TTL/CMOS logic drive levels without external bias components.
Its DFN1412D-3 package features side-wettable flanks for automated optical inspection of solder joints and supports thermal dissipation up to 450 mW on 70 µm FR4 copper, with junction-to-ambient thermal resistance of 278 K/W under standard mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage before breakdown; supports 24 V automotive supply rails with margin. |
| IO | 100 mA - Continuous output current capability; sufficient for driving LEDs, small relays, or logic inputs. |
| hFE | 60 - DC current gain at VCE = 5 V, IC = 5 mA; ensures reliable saturation with low base drive current. |
| VCE(sat) | ≤100 mV - Low saturation voltage minimizes power loss and heating during switching operation. |
| R1 / R2 | 22 kΩ / 22 kΩ - Matched internal bias resistors eliminate need for external components and reduce BOM count. |
| Tj max | 150 °C - Maximum junction temperature rating; qualified per AEC-Q101 for under-hood automotive use. |
| Package | DFN1412D-3 (SOT8009) - 1.4 × 1.2 × 0.48 mm ultra-small leadless package with side-wettable flanks for AOI. |
Pinout & Package
The PDTC124EQC-Q uses a 3-terminal DFN1412D-3 (SOT8009) package with side-wettable flanks, measuring 1.4 mm × 1.2 mm × 0.48 mm and featuring a 0.8 mm pitch. Its low 0.5 mm profile supports high-density PCB layouts and automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base via R1) | Logic-level signal entry point; current-limited by integrated 22 kΩ resistor to prevent overdrive. |
| 2 | GND (emitter) | Emitter connection and ground reference; tied internally to R2 and external circuit return path. |
| 3 | Output (collector) | Switched load connection; sinks up to 100 mA when driven high at Pin 1 with ≥1.7 V input voltage. |

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 |
|---|---|---|---|
| PDTC114EQC-Q | 10 kΩ R1/R2; lower hFE (30×); higher VI(on) (1.8 V typ) | Better suited for higher-voltage logic families (e.g., 5 V TTL) due to higher input threshold. | Select when driving from legacy 5 V microcontrollers or needing reduced sensitivity to noise. |
| PDTC144EQC-Q | 47 kΩ R1/R2; higher hFE (80×); lower IO (5 mA test condition) | Optimized for ultra-low-power MCU GPIOs with weak drive strength (e.g., ARM Cortex-M0+). | Choose for battery-powered devices requiring <1 µA standby leakage and minimal base current draw. |
Compared with PDTC114EQC-Q and PDTC144EQC-Q, PDTC124EQC-Q offers balanced input sensitivity (VI(on) = 1.7 V), moderate gain (hFE = 60), and full 100 mA output capability - making it the optimal choice for 3.3 V logic-driven automotive and industrial switching where both drive margin and load capacity matter.

FAQ
What is the maximum continuous collector current for PDTC124EQC-Q?
The PDTC124EQC-Q is rated for 100 mA continuous collector current (IO) under standard FR4 PCB mounting conditions. This rating assumes Tamb ≤ 25 °C and proper thermal layout; derating applies above 25 °C ambient, reaching zero at 150 °C junction temperature per the published power derating curve.
Does PDTC124EQC-Q require external base resistors?
No - PDTC124EQC-Q integrates both R1 (22 kΩ) and R2 (22 kΩ) bias resistors internally. This eliminates the need for external base resistors in typical digital switching applications, reducing component count, PCB area, and assembly cost while improving reliability through fewer solder joints.
Is PDTC124EQC-Q compatible with automated optical inspection (AOI)?
Yes - its DFN1412D-3 (SOT8009) package features side-wettable flanks, allowing AOI systems to inspect solder joint quality on the exposed metal sidewalls. This capability is explicitly supported in Nexperia's reflow footprint guidelines and qualifies the device for high-yield automated manufacturing in automotive and industrial production lines.
How does PDTC124EQC-Q differ from standard BC847-Q transistors?
Unlike the BC847-Q series, PDTC124EQC-Q integrates matched 22 kΩ bias resistors, enabling direct logic-level drive without external components. It also features side-wettable flanks, AEC-Q101 qualification, and tighter parameter distributions optimized for digital switching - whereas BC847-Q requires external biasing and lacks automotive qualification and AOI support.
