Product details
Overview
ADA114YUQ-7 from Diodes Incorporated is a dual PNP pre-biased transistor in SOT363 package, featuring integrated 10kΩ and 47kΩ bias resistors, AEC-Q101 qualification for automotive use, -50V VCC, and -100mA IC(MAX). It enables compact, reliable high-side switching in automotive body control modules.
For engineers reviewing the ADA114YUQ-7 datasheet, ADA114YUQ-7 pinout, ADA114YUQ-7 application, or ADA114YUQ-7 equivalent, key selection criteria include verified R1/R2 tolerance (±30%), guaranteed VI(on) ≤ -1.4V, VO(on) ≤ -0.3V at -5mA, and thermal resistance of 450°C/W on FR4.
Technical Context
This dual PNP transistor integrates two identical pre-biased elements sharing common emitter connections per channel, each with dedicated base resistors (R1 = 10kΩ, R2 = 47kΩ). Its design supports direct logic-level interface with microcontrollers operating down to -1.4V input threshold.
The device operates across -55°C to +150°C, meets AEC-Q101 stress testing requirements, and delivers 250MHz fT at VCE = -10V and IE = -5mA - enabling stable performance in automotive signal conditioning and load switching circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Max | -50V - supports high-side switching in 12V/24V automotive systems with margin against load dump transients |
| IC(MAX) | -100mA - sufficient for driving small relays, LEDs, or MOSFET gates without external current limiting |
| R1 / R2 | 10kΩ / 47kΩ - fixed bias network eliminates external components and ensures predictable turn-on at VI ≤ -1.4V |
| VO(on) | -0.1V to -0.3V @ IO = -5mA - low saturation voltage reduces power loss in continuous conduction mode |
| fT | 250MHz - enables use in moderate-speed digital switching and pulse-width modulated control signals |
| PD | 270mW - total package dissipation limit; derates linearly above +25°C ambient per 450°C/W RθJA |
| GI | 68 min - DC current gain ensures robust drive capability even under worst-case temperature and process variation |
Pinout & Package
SOT363 is a 6-pin, surface-mount, lead-free plastic package measuring 2.15mm × 2.10mm × 0.95mm (max height), rated UL 94V-0, moisture sensitivity level 1, and weighing ~0.006g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter (Channel A) | Common emitter node for first PNP transistor; connects to system ground or low-side return path |
| 2 | Base (Channel A) | Input node tied internally to R1–R2 divider; accepts logic-level control signal |
| 3 | Collector (Channel A) | High-side output node; sinks current from load connected to positive rail |
| 4 | Emitter (Channel B) | Common emitter node for second PNP transistor; electrically isolated from Pin 1 |
| 5 | Base (Channel B) | Independent input node with identical internal biasing as Pin 2 |
| 6 | Collector (Channel B) | Second high-side output; enables dual independent switching in single footprint |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood applications including temperature cycling, HTRB, and ESD testing per JESD47 |
| Integrated R1/R2 bias network | Eliminates four external resistors per channel, reducing PCB area by ≥30% vs discrete bias solutions |
| Green compound & RoHS3 compliant | Halogen- and antimony-free molding compound (<900ppm Br, <900ppm Cl, <1000ppm Sb) meets global environmental mandates |
| Thermal resistance (RθJA) | 450°C/W on standard FR4 - enables operation up to +125°C ambient without heatsinking in typical automotive layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual PNP pre-biased transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSVD114YUQ-7 | Same die, identical R1/R2 values and electrical specs; differs only in marking and traceability documentation for specific OEM programs | Approved for additional Tier-1 automotive programs requiring NSV prefix compliance | Select when sourcing requires NSV-series part number alignment per customer BOM |
| DDTA114YCA-7-F | R1 = 10kΩ, R2 = 47kΩ, but not AEC-Q101 qualified; RθJA = 500°C/W vs 450°C/W | Limited to industrial or consumer applications without automotive qualification requirements | Choose for cost-sensitive non-automotive designs where AEC-Q101 is not mandated |
Compared with NSVD114YUQ-7 and DDTA114YCA-7-F, ADA114YUQ-7 uniquely combines AEC-Q101 qualification, 450°C/W thermal performance, and production traceability in IATF 16949 facilities - making it the only option for safety-critical automotive high-side switching.

FAQ
What is the maximum allowable junction temperature for ADA114YUQ-7?
The absolute maximum junction temperature is +150°C, with continuous operation supported from -55°C to +150°C ambient. Derating begins at +25°C using RθJA = 450°C/W; at +100°C ambient, maximum power dissipation drops to 150mW per element to stay within safe thermal limits.
Can ADA114YUQ-7 be used in parallel configurations for higher current handling?
No - the device is not characterized for paralleling due to mismatch in DC current gain (GI = 68 min) and thermal coupling between channels. For >100mA loads, use a single higher-rated transistor or discrete bias solution with matched devices and individual thermal paths.
Is the SOT363 package compatible with standard reflow profiles for lead-free soldering?
Yes - the matte tin-plated leads meet MIL-STD-202 Method 208 solderability requirements and are qualified for JEDEC J-STD-020C reflow profiles, including peak temperatures up to 260°C for ≤10 seconds, with moisture sensitivity level 1 allowing unlimited floor life before assembly.
Does ADA114YUQ-7 support reverse polarity protection in automotive systems?
No - it is a PNP switching transistor, not a protection device. While VCC rating of -50V allows operation with reversed battery connections, it lacks integrated reverse-voltage blocking or clamping; external TVS diodes or MOSFET-based protection must be added for true reverse-polarity immunity.
