Diodes Incorporated DXTN3C100PSQ-13

Overview

DXTN3C100PSQ-13 from Diodes Incorporated is an AEC-Q101-qualified NPN medium-power transistor in PowerDI5060-8 package, rated for 100V V_CEO, 3A continuous collector current, <150mΩ R_CE(SAT), and operation up to +175°C. It serves as a high-reliability load switch or linear-mode pass element in automotive power management systems.

For engineers reviewing the DXTN3C100PSQ-13 datasheet, DXTN3C100PSQ-13 pinout, DXTN3C100PSQ-13 application, or DXTN3C100PSQ-13 equivalent, key selection criteria include its low saturation resistance at 3A, wettable flank for automated optical inspection, IATF16949 manufacturing compliance, and thermal robustness in under-hood environments.

Technical Context

This NPN bipolar junction transistor is optimized for medium-power switching and linear regulation, with guaranteed BV_CEO ≥ 100V and R_CE(SAT) ≤ 150mΩ at IC = 3A/IB = 300mA. Its f_T of 140MHz supports fast switching in PWM-controlled loads.

The device features a thermally enhanced PowerDI5060-8 package with R_θJL = 5.7°C/W to collector tab, enabling efficient heat transfer in compact automotive PCB layouts. It meets JESD22-A114 HBM ESD rating of 4000V and operates across –55°C to +175°C junction temperature range.

FAQ

What is the maximum allowable continuous power dissipation for DXTN3C100PSQ-13 on a standard 25mm × 25mm 2oz copper PCB?

At TA = +25°C with still air, the device is rated for 2.5W continuous power dissipation when mounted per note 5 in the datasheet. This assumes a 25mm × 25mm 2oz copper pad layout on FR4. Derating is required above +25°C ambient, following the 60°C/W R_θJA slope until reaching the 175°C T_J limit.

Does DXTN3C100PSQ-13 support linear-mode operation, and what design considerations apply?

Yes-it is explicitly characterized for linear-mode use in voltage regulators and current sinks. Key considerations include maintaining junction temperature below 175°C using the R_θJL = 5.7°C/W path to the collector tab, limiting second breakdown energy during transient overloads, and ensuring base drive remains within the 500mA I_B absolute maximum rating.

How does the wettable flank feature improve manufacturing yield?

The wettable flank geometry on all eight terminals allows automated optical inspection (AOI) systems to reliably detect solder fillet height, wetting angle, and voiding on side-view images. This eliminates reliance on X-ray for hidden-joint verification and reduces false-fail rates in high-volume SMT lines producing automotive-grade assemblies.

Is DXTN3C100PSQ-13 qualified for use in safety-critical automotive functions like airbag deployment?

No-while AEC-Q101 qualified and manufactured in IATF16949 facilities, it is not certified for ASIL-B or higher applications. Diodes Incorporated explicitly excludes use in life support systems unless authorized in writing. For airbag controllers, dedicated ASIL-rated ICs with functional safety documentation are required.
