Product details
Overview
ACX124EUQ-13R from Diodes Incorporated is a small-signal complementary pre-biased dual transistor in SOT363 package, integrating one NPN and one PNP transistor with built-in 22 kΩ bias resistors per emitter. It delivers ±100 mA max collector current, ±30 mA output current, and operates across –55°C to +150°C. It is AEC-Q101 qualified and manufactured in IATF16949-certified facilities for automotive signal switching applications.
For engineers reviewing the ACX124EUQ-13R datasheet, ACX124EUQ-13R pinout, ACX124EUQ-13R application, or ACX124EUQ-13R equivalent, key selection criteria include its dual complementary topology, matched resistor tolerance (±30% R1, ±20% R2/R1), guaranteed VI(on)/VI(off) thresholds, and thermal derating behavior on FR4 boards.
Technical Context
The ACX124EUQ-13R integrates two monolithic transistors - one NPN and one PNP - each with identical internal 22 kΩ base-emitter and base-collector bias resistors. Its complementary configuration enables push-pull or level-shifting operation without external bias networks.
It supports bidirectional input voltage ranges: –40 V to +10 V for PNP section and –10 V to +40 V for NPN section, with guaranteed turn-on at |VI| ≥ 3.0 V and turn-off at |VI| ≤ 0.5 V. DC current gain (hFE) is ≥60 at IO = 5 mA, and fT is 250 MHz under specified test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Max | 50 V - Supports rail-to-rail switching in 24 V and 48 V automotive subsystems without breakdown risk. |
| IC(Max) | ±100 mA - Enables direct drive of small relays, LEDs, or logic-level interface loads without external amplification. |
| R1, R2 | 22 kΩ ±30% - Integrated bias network eliminates 4 external resistors per channel, reducing BOM count and layout area. |
| VI(on)/VI(off) | NPN: 1.9/0.5 V; PNP: –1.9/–0.5 V - Ensures clean digital logic-level compatibility with 3.3 V and 5 V microcontrollers. |
| PD | 270 mW - Sufficient for continuous 20 mA switching at ambient ≤85°C on standard FR4 with minimum copper pad layout. |
| TJ Range | –55°C to +150°C - Validated for under-hood automotive environments including engine control modules and body electronics. |

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 |
|---|---|---|---|
| NSBC114YDXV6T1G | Same SOT363 package, but only NPN+NPN configuration; no PNP section. | Limited to dual low-side switching; cannot replace ACX124EUQ-13R in push-pull or high-side drive roles. | Select only if application requires two identical NPN channels and no high-side capability. |
| EMH11T2R | Includes integrated ESD protection (±8 kV HBM); R1/R2 = 10 kΩ (not 22 kΩ); lower fT (150 MHz). | Better ESD robustness for exposed I/O ports, but reduced bandwidth and different bias point - may require revalidation of VI thresholds. | Choose when system-level ESD immunity is prioritized over frequency response and exact threshold matching. |
Compared with NSBC114YDXV6T1G and EMH11T2R, the ACX124EUQ-13R uniquely provides true complementary (NPN+PNP) operation with 22 kΩ biasing and AEC-Q101 validation - making it the only drop-in solution for automotive push-pull interfaces requiring matched turn-on characteristics and temperature resilience.

FAQ
What is the maximum operating temperature for ACX124EUQ-13R?
The ACX124EUQ-13R is rated for junction temperatures from –55°C to +150°C, with full electrical performance guaranteed across this range. Derating begins above +85°C ambient on standard FR4 boards, where power dissipation must be reduced linearly per the 450°C/W RθJA specification.
Can ACX124EUQ-13R replace discrete transistor-resistor combinations?
Yes - it replaces two transistors and four bias resistors (two per device) in standard switching configurations. The integrated 22 kΩ R1/R2 network matches typical 5 V logic drive requirements, and the guaranteed VI(on) ≤ 3.0 V and VI(off) ≥ 0.5 V eliminate need for external level-shifting.
Is ACX124EUQ-13R pin-compatible with other SOT363 pre-biased transistors?
No - pin assignment is specific to its complementary NPN+PNP topology: Pin 1 = NPN emitter, Pin 2 = NPN base, Pin 3 = PNP emitter, Pin 4 = PNP collector, Pin 5 = PNP base, Pin 6 = NPN collector. Other SOT363 pre-biased parts (e.g., dual-NPN types) use different internal connectivity.
Does ACX124EUQ-13R support PWM switching at 25 kHz?
Yes - with fT = 250 MHz and typical turn-on/turn-off times <100 ns, it fully supports 25 kHz PWM for LED dimming and motor control. Layout-dependent parasitic inductance remains the dominant limiting factor, not device bandwidth.
