Diodes Incorporated ADC114YUQ-7

Overview

ADC114YUQ-7 from Diodes Incorporated is an AEC-Q101 qualified NPN pre-biased dual transistor in SOT363 package, featuring integrated 10 kΩ and 47 kΩ bias resistors, 100 mA maximum collector current per element, and operation from −55°C to +150°C. It is used in automotive signal switching and level translation circuits where space-constrained dual-channel discrete logic interface is required.

For engineers reviewing the ADC114YUQ-7 datasheet, ADC114YUQ-7 pinout, ADC114YUQ-7 application, or ADC114YUQ-7 equivalent, key selection factors include guaranteed VI(on) ≤1.4 V at IO = 1 mA, VO(on) ≤0.3 V at IO/II = 5 mA/0.25 mA, R1/R2 tolerance (±30%/±20%), fT = 250 MHz, and IATF 16949 manufacturing compliance.

Technical Context

This dual NPN transistor integrates two independent pre-biased elements sharing no internal connection-each with its own base-emitter resistor network (R1 = 10 kΩ, R2 = 47 kΩ). The device operates as a digital switch or logic-level translator, with guaranteed turn-on at VI ≥1.4 V and turn-off at VI ≤0.3 V under defined load conditions.

It supports high-speed switching up to 250 MHz (fT), delivers 100 mA IC(max) per channel, and maintains stable performance across −55°C to +150°C. Its SOT363 package enables compact placement on automotive PCBs while meeting J-STD-020 Level 1 moisture sensitivity and UL 94V-0 flammability requirements.

FAQ

Is ADC114YUQ-7 pin-compatible with standard SOT363 dual transistors?

Yes, ADC114YUQ-7 uses the industry-standard SOT363 outline with 0.65 mm pitch and identical mechanical dimensions. Pin 1–3 serve E-B-C for the first NPN, and Pins 4–6 serve C-B-E for the second NPN-matching JEDEC MO-178AB and Diodes' own SOT363 pin map.

What is the maximum allowable power dissipation per channel at +85°C ambient?

At TA = +85°C, derating from the 270 mW total PD requires limiting each channel to ≤150 mW. With RθJA = 450 °C/W, junction temperature rise is ~67.5°C above ambient, keeping TJ ≤152.5°C-within the −55°C to +150°C rating only if ambient stays ≤82.5°C or board layout improves thermal conduction.

Does ADC114YUQ-7 support 1.8 V logic input levels?

No-its guaranteed VI(on) is ≤1.4 V at IO = 1 mA, but typical VI(on) is ~1.1 V. At 1.8 V input, the device will saturate, yet the datasheet does not specify performance below 2.0 V. For 1.8 V systems, verify actual VO(on) and propagation delay in prototype testing.

How is PPAP documentation provided for ADC114YUQ-7 in automotive programs?

PPAP documentation-including PSW, dimensional reports, material certifications, and test data-is available upon request through Aetrix Electronics' automotive support team.
