Product details
Overview
DCX123JH-7 from Diodes Incorporated is a complementary NPN/PNP pre-biased small-signal transistor pair in SOT563 package, featuring integrated 2.2 kΩ and 47 kΩ bias resistors (R1/R2), ±50 V breakdown voltage per section, 100 mA max output current (NPN/ PNP), and 150 mW total power dissipation. It functions as a dual-channel level-shifting or logic interface switch in compact space-constrained digital I/O circuits.
For engineers reviewing the DCX123JH-7 datasheet, DCX123JH-7 pinout, DCX123JH-7 application, or DCX123JH-7 equivalent, key selection criteria include verified input threshold voltages (VI(ON) = +1.1 V / −1.1 V at IO = 5 mA), guaranteed saturation performance (VCE(SAT) ≤ ±0.3 V), confirmed SOT563 mechanical compatibility, and validated complementary switching behavior across −55°C to +150°C operating range.
Technical Context
This device integrates matched NPN and PNP transistors with monolithic bias networks on a single die, enabling push-pull or complementary switching without external resistors. Its dual-section architecture supports bidirectional signal conditioning with independent input control per channel and shared emitter connections for common-ground configurations.
The R1 = 2.2 kΩ / R2 = 47 kΩ resistor network defines precise turn-on thresholds and current gain scaling (GL = 80) for both sections, ensuring predictable logic-level interfacing under 5 V supply conditions while maintaining <0.5 µA leakage in OFF state (IO(OFF)) and <0.3 V saturation voltage under 5 mA load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO (NPN/PNP) | ±50 V - Supports rail-to-rail switching in 5 V–24 V logic and interface applications without external clamping. |
| IO (Max) | ±100 mA - Drives moderate-current loads such as LED indicators, relay coils, or gate inputs of power MOSFETs. |
| R1 / R2 | 2.2 kΩ / 47 kΩ - Sets fixed base bias ratio for stable, resistor-free logic-level translation with minimal design iteration. |
| VI(ON) | +1.1 V / −1.1 V - Enables direct connection to 3.3 V or 5 V CMOS/TTL outputs without level-shifter ICs. |
| VCE(SAT) | ≤ ±0.3 V - Minimizes conduction loss and self-heating in high-duty-cycle switching, critical for thermal reliability in SOT563. |
| PD (Total) | 150 mW - Matches FR-4 board thermal limits (RθJA = 833°C/W); requires no heatsinking in typical low-power digital use cases. |
| TJ Range | −55°C to +150°C - Qualified for automotive under-hood, industrial PLC I/O, and extended-temperature embedded control environments. |

| 4 (PNP Emitter) | PNP emitter terminal | Common emitter node for PNP section; electrically tied to Pin 1 for push-pull emitter-follower or totem-pole topologies. |
| 5 (PNP Base) | PNP base connection | Connected via internal 47 kΩ resistor (R2) to Pin 6; provides high-impedance base bias for low-leakage PNP turn-on. |

| Green, RoHS-compliant construction | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) meets automotive and industrial environmental mandates. |
| Low saturation voltage | VCE(SAT) ≤ ±0.3 V at IC/IB = 5 mA/0.25 mA ensures minimal power loss and heat generation in battery-powered or thermally constrained systems. |
| High input impedance | Input current IL = ±1.8 mA at VI = ±5 V enables direct drive from microcontroller GPIOs without buffer amplifiers. |

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 |
|---|---|---|---|
| DCX114EH-7 | R1 = 10 kΩ, R2 = 10 kΩ; higher input current (±0.88 mA), lower VI(ON) (+0.5 V / −0.5 V) | Better suited for 1.8 V logic interfaces but less noise-immune in noisy industrial environments | Select when interfacing with low-voltage MCUs and requiring tighter input threshold control. |
| DCX143EH-7 | R1 = 4.7 kΩ, R2 = 4.7 kΩ; GL = 20, higher IO (±100 mA), VI(ON) = +1.9 V / −1.9 V | Optimized for 3.3 V–5 V systems needing stronger drive and higher noise margin | Choose for driving heavier capacitive loads or where faster switching edge rates are required. |
Compared with DCX114EH-7 and DCX143EH-7, DCX123JH-7 offers intermediate input sensitivity (±1.1 V threshold) and superior noise immunity due to its asymmetric R1/R2 ratio-ideal for mixed-voltage industrial I/O where 5 V logic must coexist with legacy 3.3 V peripherals.

FAQ
What is the maximum continuous current rating for each transistor section?
Each section (NPN and PNP) supports a maximum continuous output current of ±100 mA at TA = +25°C, derated linearly above 25°C per the 833°C/W junction-to-ambient thermal resistance. At 75°C ambient, the usable current drops to approximately ±75 mA to maintain safe junction temperature below 150°C.
Can DCX123JH-7 be used in high-frequency switching applications?
No-this device is optimized for DC and low-frequency switching (≤1 MHz). Its gain-bandwidth product (fT) is not specified for DCX123JH-7 in the datasheet; only DCX143TH/DCX114TH variants list fT = 250 MHz. For >100 kHz PWM or RF switching, discrete transistors with characterized fT should be selected.
How are the internal bias resistors connected within the SOT563 package?
R1 (2.2 kΩ) connects between Pin 2 (NPN base) and Pin 3 (NPN collector); R2 (47 kΩ) connects between Pin 5 (PNP base) and Pin 6 (PNP collector). Neither resistor ties to the common emitter pins (1 and 4), preserving independent base bias control for each transistor section.
Is DCX123JH-7 suitable for automotive AEC-Q101 qualification?
No-the DCX123JH-7 is not AEC-Q101 qualified. While it operates across −55°C to +150°C and meets RoHS/Green requirements, Diodes Incorporated does not list this specific variant in its AEC-Q101 stress-tested portfolio. For automotive safety-critical applications, select the AEC-Q101–qualified DDC123JH or equivalent.
