Product details
Overview
ADTA114YUAQ from Diodes Incorporated is a PNP pre-biased transistor in SOT323 package, designed for automotive signal switching and level translation. It features integrated 10 kΩ and 47 kΩ bias resistors, AEC-Q101 qualification, -100 mA maximum collector current, and -50 V VCC rating. It operates across -55 °C to +150 °C and delivers DC current gain (GI) ≥68 at -10 mA.
For engineers reviewing the ADTA114YUAQ datasheet, ADTA114YUAQ pinout, ADTA114YUAQ application, or ADTA114YUAQ equivalent, key selection criteria include its pre-biased resistor ratio (R2/R1 = 4.7), guaranteed ON/OFF thresholds (-1.4 V / -0.3 V), low saturation voltage (-0.1 V typ. at -5 mA), automotive-grade reliability, and SOT323 thermal performance (RθJA = 375 °C/W).
Technical Context
This device integrates a PNP bipolar junction transistor with two monolithically embedded bias resistors-R1 (10 kΩ) connected between base and emitter, and R2 (47 kΩ) between base and input terminal-enabling single-resistor drive logic interface. Its internal topology eliminates external bias components for digital input conditioning.
The transistor supports rail-to-rail input operation from -40 V to +6 V and guarantees switching behavior: turn-on when input voltage exceeds -1.4 V (VI(on)), and turn-off below -0.3 V (VI(off)). It maintains stable DC current gain (GI ≥68) and 250 MHz fT under -10 V VCE, -5 mA IE conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar pre-biased PNP transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSV114YUT1G | Same R1/R2 values (10 kΩ/47 kΩ), identical SOT-323 package, but rated only to +125 °C TJ (vs. +150 °C) | Lacks AEC-Q101 qualification and PPAP support; not approved for automotive production | Select when cost sensitivity outweighs automotive qualification requirements |
| DXTA114YCA-7 | Same electrical specs and AEC-Q101 rating, but in SC-70 (SOT-323 equivalent) with slightly different marking and reel packaging | Identical functional use; differs only in tape-and-reel logistics (7-inch vs. 13-inch reel) | Select when matching existing SMT line setup or preferred distributor inventory format |
Compared with NSV114YUT1G and DXTA114YCA-7, ADTA114YUAQ uniquely combines full AEC-Q101 qualification, +150 °C operation, and 13-inch reel packaging-making it optimal for Tier-1 automotive production programs requiring traceability, thermal headroom, and volume procurement efficiency.

FAQ
What is the function of the two internal resistors in ADTA114YUAQ?
The ADTA114YUAQ integrates a 10 kΩ resistor (R1) between base and emitter, and a 47 kΩ resistor (R2) between base and input terminal. This configuration provides automatic biasing for PNP transistor operation, allowing direct connection to logic-level inputs without external components. R2 pulls the base toward the input voltage, while R1 provides a discharge path to emitter, ensuring predictable turn-off behavior and noise immunity.
Can ADTA114YUAQ be used in high-frequency switching applications?
Yes-the ADTA114YUAQ has a gain-bandwidth product (fT) of 250 MHz under standard test conditions (VCE = -10 V, IE = -5 mA). While optimized for DC and low-frequency switching (e.g., PWM up to ~100 kHz), its bandwidth supports fast edge transitions in automotive signal conditioning and sensor interface circuits where rise/fall time consistency matters more than RF performance.
Is the SOT323 package of ADTA114YUAQ compatible with standard reflow profiles?
Yes-ADTA114YUAQ's SOT323 package is rated for moisture sensitivity level 1 per J-STD-020 and uses matte tin-plated leads solderable per MIL-STD-202, Method 208. It supports industry-standard lead-free reflow profiles (peak temperature ≤260 °C), and its 0.006 g mass and thermal resistance (RθJA = 375 °C/W) allow reliable mounting on FR-4 boards with minimum recommended pad layout.
How does ADTA114YUAQ differ from generic PNP transistors in automotive designs?
Unlike discrete PNP transistors, ADTA114YUAQ integrates precision-matched bias resistors (±30% R1 tolerance, ±20% R2/R1 ratio), guarantees switching thresholds (-1.4 V ON, -0.3 V OFF), and is fully AEC-Q101 qualified with PPAP documentation. It eliminates design uncertainty in bias network selection, reduces validation effort, and ensures consistent performance across temperature and production lots in safety-critical automotive functions.
