Product details
Overview
ADTA114EUAQ from Diodes Incorporated is a PNP pre-biased small-signal transistor in SOT323 package, featuring integrated 10 kΩ base-emitter and base-collector bias resistors, −100 mA maximum collector current, −50 V VCEO, and AEC-Q101 qualification for automotive applications such as LED load switching and sensor interface circuits.
For engineers reviewing the ADTA114EUAQ datasheet, ADTA114EUAQ pinout, ADTA114EUAQ application, or ADTA114EUAQ equivalent, key selection criteria include guaranteed DC current gain (hFE ≥ 30 at IC = −5 mA), low saturation voltage (VCE(SAT) ≤ −0.3 V at IC/IB = −10 mA/−0.5 mA), thermal resistance (RθJA = 375 °C/W), and automotive-grade reliability under −55 °C to +150 °C operation.
Technical Context
This device integrates two precision-matched 10 kΩ biasing resistors (R1 = R2 = 10 kΩ, ±30% tolerance) to eliminate external base drive components in digital switching applications. Its PNP topology enables high-side load control with logic-level input compatibility down to −1.1 V (VL(OFF)) and active pull-down capability.
The SOT323 package supports automated assembly and delivers 330 mW power dissipation on FR4 PCBs. It operates across −55 °C to +150 °C with full AEC-Q101 stress qualification, including HTOL, temperature cycling, and ESD (HBM ≥ 8 kV).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum allowable collector-to-emitter voltage before breakdown in open-base configuration. |
| IC(max) | −100 mA: Continuous collector current rating defining safe switching capacity for automotive loads. |
| hFE | ≥30: Minimum DC current gain at VCE = −5 V, IC = −5 mA - ensures reliable saturation under defined drive conditions. |
| VCE(SAT) | ≤ −0.3 V at IC/IB = −10 mA/−0.5 mA: Confirmed low-saturation voltage enabling minimal power loss in on-state switching. |
| RθJA | 375 °C/W: Junction-to-ambient thermal resistance on minimum-copper FR4 board - defines temperature rise per watt dissipated. |
| fT | 250 MHz: Gain-bandwidth product at VCE = −10 V, IE = −5 mA - indicates usable frequency range for small-signal amplification. |
Pinout & Package
Package: SOT323 - ultra-small surface-mount plastic case (2.15 mm × 2.10 mm × 0.95 mm), lead-free, halogen-free, moisture sensitivity level 1, weight ≈ 0.006 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Emitter terminal of PNP transistor | Connected to higher potential rail in high-side switch configurations; current flows out of this pin. |
| 2 (Base) | Internal connection point between R1 and R2 | Provides bias node for resistor-divider network; accepts logic-level input (−1.1 V to −3.0 V threshold). |
| 3 (Collector) | Collector terminal of PNP transistor | Connected to load; sinks current when device is active; rated for −50 V reverse blocking. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias resistors | Matched R1 = R2 = 10 kΩ ±30%, eliminating external base components and reducing BOM count in digital interface designs. |
| AEC-Q101 qualification | Fully qualified per AEC-Q101 Rev D - validated for automotive underhood environments including temperature cycling, HTOL, and ESD robustness. |
| Low VCE(SAT) | ≤ −0.3 V at IC/IB = −10 mA/−0.5 mA - minimizes conduction loss and self-heating during sustained on-state operation. |
| Green compound packaging | Halogen- and antimony-free molding compound (Br+Cl < 1500 ppm, Sb < 1000 ppm), UL 94V-0 rated, fully RoHS compliant. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP pre-biased transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSV114EUAZT1G | Same SOT323 package, identical R1/R2 = 10 kΩ, but rated only to +125 °C TJ (vs. +150 °C), no AEC-Q101 documentation provided. | Not qualified for under-hood automotive use above 125 °C; suitable for cabin or industrial control. | Select when AEC-Q101 is not required and operating temperature stays below 125 °C. |
| DXTA114EUC-7 | SOT363 package (3× smaller footprint than SOT323), same electrical specs, but lower PD = 200 mW (vs. 330 mW) and RθJA = 450 °C/W. | Higher thermal resistance limits continuous current in compact layouts; best for space-constrained, low-duty-cycle uses. | Select when PCB area is critical and thermal derating can be accommodated. |
Compared with NSV114EUAZT1G and DXTA114EUC-7, ADTA114EUAQ uniquely combines AEC-Q101 qualification, +150 °C operation, and 330 mW power handling - making it the only choice for high-reliability automotive switching where thermal margin and qualification compliance are mandatory.

FAQ
What is the maximum operating temperature for ADTA114EUAQ?
The ADTA114EUAQ is rated for junction temperatures from −55 °C to +150 °C and is qualified per AEC-Q101 for automotive under-hood applications. Its thermal resistance (RθJA = 375 °C/W) allows safe operation up to +150 °C junction temperature when mounted on FR4 with minimum recommended copper pad layout.
Does ADTA114EUAQ require external base resistors?
No. ADTA114EUAQ integrates two 10 kΩ bias resistors (R1 and R2) internally, forming a complete pre-biased PNP configuration. This eliminates the need for external base resistors in standard digital switching applications, reducing component count and PCB area.
Is ADTA114EUAQ pin-compatible with standard SOT-23 transistors?
No. ADTA114EUAQ uses the SOT323 package (2.15 mm × 2.10 mm), which is physically smaller than SOT-23 and has different pin assignments. Its pin 1 is emitter, pin 2 is base, and pin 3 is collector - distinct from many generic SOT-23 PNP transistors that use alternate pinouts.
What is the typical VCE(SAT) at IC = −10 mA?
The typical VCE(SAT) is −0.1 V, with a maximum of −0.3 V at IC/IB = −10 mA/−0.5 mA and VCC = −5 V. This low saturation voltage ensures minimal power loss and heat generation during sustained on-state operation in automotive load-switching applications.
