Diodes Incorporated ADC114EUQ-13

Overview

ADC114EUQ-13 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 signal conditioning and digital logic interface circuits where space-constrained dual-transistor switching with built-in biasing is required.

For engineers reviewing the ADC114EUQ-13 datasheet, ADC114EUQ-13 pinout, ADC114EUQ-13 application, or ADC114EUQ-13 equivalent, key selection criteria include its dual-NPN topology with matched bias resistors, AEC-Q101 qualification for automotive use, SOT363 footprint compatibility, and guaranteed turn-on/turn-off voltage thresholds under 5 V logic drive.

Technical Context

This device integrates two identical NPN transistors with monolithically embedded base-emitter and base-resistor networks-each with R1 = R2 = 10 kΩ ±30% and R2/R1 ratio tolerance of ±20%. It operates across –55 °C to +150 °C and supports 50 V V_CC, enabling robust interfacing between low-voltage logic and higher-voltage loads.

The transistor exhibits a typical f_T of 250 MHz at V_CE = 10 V and I_E = 5 mA, confirming suitability for medium-speed digital switching. Its VO(on) ≤ 0.3 V at IO/IL = 10 mA / 0.5 mA ensures low-saturation operation in driver and level-shifting roles.

FAQ

Is ADC114EUQ-13 pin-compatible with other SOT363 dual-transistor packages?

Yes - ADC114EUQ-13 uses the standard SOT363 pinout (E-B-C / C-B-E), matching industry conventions for dual NPN pre-biased transistors. Pin 1 is emitter of Q1, Pin 2 is base of Q1, Pin 3 is collector of Q1, Pin 4 is collector of Q2, Pin 5 is base of Q2, and Pin 6 is emitter of Q2. This layout is consistent with Diodes' own NSVD series and ON Semiconductor's EMD series.

What is the maximum operating temperature for continuous use in automotive under-hood environments?

The ADC114EUQ-13 is rated for junction temperatures from –55 °C to +150 °C and is AEC-Q101 qualified, meaning it has passed extended temperature cycling, high-temperature operating life (HTOL), and other stress tests required for under-hood deployment. When mounted per recommended SOT363 pad layout on FR-4, its R_θJA of 450 °C/W allows sustained operation at ambient temperatures up to +125 °C with appropriate derating.

Does the device support 1.8 V logic input drive?

No - the datasheet guarantees reliable turn-on only when input voltage exceeds 1.9 V (typical) and 3.0 V (max), and turn-off when below 0.5 V (min). At 1.8 V, the device may operate in linear region with unpredictable gain and increased power dissipation. It is specified for 3.3 V or 5 V logic families, not sub-2 V I/O standards.

Can ADC114EUQ-13 be used in linear amplifier configurations?

No - this device is optimized for switching operation with built-in bias resistors that fix base current. Its gain-bandwidth product (250 MHz) and DC current gain (G_I ≥ 30) are specified under switching conditions. For linear amplification, externally biased discrete transistors or dedicated amplifier ICs with adjustable bias networks are required.
