Diodes Incorporated ADC114YUQ-13

Overview

ADC114YUQ-13 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, 50 V V_CC, 100 mA I_C(MAX), and 250 MHz f_T, used for automotive logic-level signal switching and interface buffering.

For engineers reviewing the ADC114YUQ-13 datasheet, ADC114YUQ-13 pinout, ADC114YUQ-13 application, or ADC114YUQ-13 equivalent, key selection criteria 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 compliance, thermal derating per element (≤150 mW), and AEC-Q101 qualification status for automotive control modules.

Technical Context

This dual NPN transistor integrates two identical pre-biased elements sharing common emitter connections, each with separate base resistors (R1 = 10 kΩ, R2 = 47 kΩ) enabling direct TTL/CMOS-compatible input drive without external biasing. It operates across –55 °C to +150 °C and supports rail-to-rail input voltage swing from –6 V to +40 V.

The device delivers DC current gain (GI) ≥ 80 at VO = 5 V and IO = 5 mA, with f_T = 250 MHz under V_CE = 10 V, I_E = 5 mA conditions-suitable for medium-speed digital switching but not RF amplification. Thermal resistance R_θJA = 450 °C/W is specified for FR4 board mounting with minimum pad layout.

FAQ

Is ADC114YUQ-13 pin-compatible with standard SOT363 dual transistors?

Yes-ADC114YUQ-13 uses the industry-standard SOT363 pinout (1:E1, 2:B1, 3:E2, 4:C2, 5:C1, 6:B2) and shares mechanical dimensions with generic SOT363 packages. Its internal resistor network does not alter terminal assignment, ensuring drop-in replacement in layouts designed for dual NPN transistors with external biasing.

What is the maximum allowable junction temperature during continuous operation?

The ADC114YUQ-13 has an operating junction temperature range of –55 °C to +150 °C. At ambient temperatures up to +85 °C and with proper PCB copper pour, the device sustains continuous operation at full 100 mA per channel, provided total power dissipation remains ≤270 mW and per-element limit (≤150 mW) is observed per derating guidelines.

Does the 47 kΩ R2 resistor connect to ground or to the emitter?

R2 connects between the base and emitter terminals of each transistor-confirmed by the schematic in DS38824 Rev. 3–2, page 1. This configuration forms a classic pre-biased topology that ensures stable turn-off behavior and reduces sensitivity to leakage currents, especially critical in automotive environments with wide temperature swings.

Can ADC114YUQ-13 be used in linear amplifier configurations?

No-it is optimized for saturated switching, not linear amplification. The datasheet specifies f_T = 250 MHz "for reference only" and omits small-signal parameters like h_FE vs. I_C curves or noise figures. Its guaranteed VI(on)/VI(off) thresholds and VO(on) specification confirm intended use as a digital switch, not an analog gain stage.
