Diodes Incorporated ADC114EUQ-7

Overview

ADC114EUQ-7 from Diodes Incorporated is an AEC-Q101 qualified NPN pre-biased dual transistor in SOT363 package, featuring integrated 10 kΩ input bias resistors (R1 = R2 = 10 kΩ), 100 mA maximum collector current per element, and guaranteed switching at VI(on) ≤ 3.0 V and VI(off) ≥ 0.5 V. It is used in automotive body control modules for discrete logic-level signal translation and load switching.

For engineers reviewing the ADC114EUQ-7 datasheet, ADC114EUQ-7 pinout, ADC114EUQ-7 application, or ADC114EUQ-7 equivalent, key selection criteria include input resistor tolerance (±30%), resistance ratio tolerance (±20%), VO(on) ≤ 0.3 V at IO/Il = 10 mA / 0.5 mA, and thermal resistance RθJA = 450 °C/W on FR-4 board.

Technical Context

This dual NPN transistor integrates matched base-emitter bias networks to eliminate external resistors in digital interface circuits. Each channel operates with DC current gain (hFE) ≥ 30 at VO = 5 V, IO = 5 mA, and supports switching up to 250 MHz fT under VCE = 10 V, IE = 5 mA conditions.

The device is rated for −55 °C to +150 °C operation, meets IATF 16949 manufacturing standards, and delivers 270 mW total power dissipation (150 mW per element max) with 0.006 g mass and UL 94V-0 mold compound.

FAQ

What is the maximum allowable continuous collector current per channel?

The ADC114EUQ-7 is rated for 100 mA maximum collector current per transistor element under TA = +25°C, with derating required above 25°C per the 450 °C/W thermal resistance. At 85°C ambient, maximum safe continuous current drops to approximately 65 mA per channel to maintain TJ ≤ 150°C.

Does the device support 3.3 V logic-level input directly?

Yes - VI(on) is guaranteed ≤ 3.0 V and VI(off) ≥ 0.5 V at TA = +25°C, making it fully compatible with 3.3 V CMOS/TTL outputs. The internal 10 kΩ bias network draws only 0.88 mA typical at 5 V input, ensuring robust drive from standard microcontroller GPIOs.

Is the SOT363 package lead-free and RoHS compliant?

Yes - the ADC114EUQ-7 uses matte tin-plated leads and green molding compound meeting RoHS 3 (2015/863/EU), halogen-free (<900 ppm Br/Cl, <1000 ppm Sb), and antimony-free requirements. It is certified to J-STD-020 Moisture Sensitivity Level 1.

Can both channels operate independently with separate inputs and outputs?

Yes - Pins 1 and 6 are isolated input terminals each feeding its own NPN transistor; Pins 2/3 and Pins 5/4 form two independent emitter-collector pairs. No shared bias or signal paths exist between channels, enabling true dual-channel operation in multiplexed or redundant circuits.
