Product details
Overview
DCX124EU-7-F from Diodes Incorporated is a complementary pre-biased NPN+PNP transistor pair in SOT363, featuring integrated 22 kΩ base resistors (R1 = R2), 50 V VO, ±30 mA continuous output current per section, and AEC-Q101 qualification for automotive signal switching applications such as LED driver bias control and level-shifting logic interfaces.
For engineers reviewing the DCX124EU-7-F datasheet, DCX124EU-7-F pinout, DCX124EU-7-F application, or DCX124EU-7-F equivalent, key selection criteria include input threshold voltage (VI(on) = 1.9–3.0 V), on-state output voltage (VO(on) ≤ 0.3 V), DC current gain (GI = 56–60), thermal resistance (RθJA = 625 °C/W), and dual-channel complementary operation in a 6-pin surface-mount package.
Technical Context
This device integrates matched NPN and PNP transistors with identical 22 kΩ input bias resistors on both sections, enabling symmetrical high-side and low-side switching without external base resistors. It supports bidirectional logic-level translation between 3.3 V/5 V domains while maintaining rail-to-rail input voltage tolerance (±40 V).
The SOT363 package houses two independent transistor channels sharing a common emitter configuration per section, with pin 3 (COM1) and pin 4 (COM2) serving as isolated emitter terminals - allowing independent biasing and load referencing for push-pull or totem-pole output stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VO | 50 V - Maximum supply voltage rating per section; enables use in 24 V automotive and industrial bus interfaces. |
| IO | ±30 mA - Continuous output current per transistor; sufficient for driving small-signal loads like optocoupler LEDs or logic gate inputs. |
| VI(on) | 1.9–3.0 V @ VO = 0.3 V, IO = 5 mA - Input turn-on threshold; compatible with standard CMOS/TTL logic outputs without level shifting. |
| VO(on) | ≤ 0.3 V @ IO/IL = 10 mA / 0.5 mA - Low saturation voltage ensures minimal power loss and heat generation in switching mode. |
| GI | 56–60 - DC current gain at VO = 5 V, IO = 5 mA; provides predictable current amplification for precise load control. |
| R1, R2 | 22 kΩ ±30% - Integrated base resistors eliminate external components and reduce PCB area in space-constrained designs. |
| PD | 200 mW - Total package power dissipation; derates linearly above +25°C ambient per 625 °C/W thermal resistance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar complementary pre-biased transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DCX144EU-7-F | 47 kΩ bias resistors (vs. 22 kΩ); higher VI(on) (1.9–3.0 V) but lower input current (0.18 mA). | Better suited for high-impedance MCU outputs where drive strength is limited; reduced power consumption in always-on monitoring nodes. | Select when interfacing with ultra-low-power microcontrollers or battery-backed systems requiring <0.2 mA input loading. |
| DCX114YU-7-F | Asymmetric resistors (R1 = 10 kΩ, R2 = 47 kΩ); optimized for unidirectional logic translation with tighter VI(off) (0.3 V). | Ideal for single-direction level shifting (e.g., 5 V → 3.3 V only), not push-pull operation; lower noise immunity in noisy environments. | Choose for cost-sensitive consumer electronics where only one-sided switching is required and asymmetric gain is acceptable. |
Compared with DCX144EU-7-F and DCX114YU-7-F, DCX124EU-7-F offers balanced NPN/PNP biasing and optimal drive capability for bidirectional signal routing, making it the preferred choice for symmetric switching topologies like H-bridge gate drivers and dual-rail logic buffers.

FAQ
What is the maximum operating temperature for DCX124EU-7-F?
The device supports an operating junction temperature range of −55 °C to +150 °C. Its thermal resistance (RθJA = 625 °C/W) requires derating above +25 °C ambient; at +85 °C ambient, maximum power dissipation drops to 100 mW to maintain safe junction temperature.
Can DCX124EU-7-F replace discrete transistors in existing designs?
Yes - it directly replaces two discrete NPN and PNP transistors plus four external base resistors. Pin compatibility with standard SOT363 footprints allows drop-in replacement, provided layout accommodates independent emitter connections (pins 3 and 4) and maintains minimum pad spacing per Diodes' recommended layout.
Is DCX124EU-7-F suitable for PWM-driven LED dimming?
Yes - its 100 mA peak output current (ICM) and <100 ns typical switching times support PWM frequencies up to 100 kHz. The matched NPN/PNP characteristics ensure consistent duty-cycle fidelity across both high-side and low-side LED current paths.
Does DCX124EU-7-F require external decoupling capacitors?
No - the device does not integrate internal regulation or oscillation-prone circuitry. However, a 100 nF ceramic capacitor placed near the VCC connection (pins 2 and 5) is recommended to suppress high-frequency noise in automotive or industrial environments with fast-switching loads.
