Diodes Incorporated recommends a PCB layout with a solid ground plane and thermal vias under the package to improve heat dissipation. A minimum of 2oz copper thickness is recommended for the PCB.
To ensure reliable operation at high temperatures, it's essential to follow the recommended operating conditions, including junction temperature (Tj) and ambient temperature (Ta). Additionally, consider using a heat sink or thermal interface material to reduce thermal resistance.
Although the datasheet specifies the recommended operating voltage range, it's essential to note that the maximum allowable voltage on the input pins is typically 1.5V to 2V above the recommended supply voltage to prevent damage from electrostatic discharge (ESD) or voltage spikes.
The DMTH8028LPSWQ-13 is an industrial-grade device, but it may not meet the specific requirements for high-reliability or automotive applications. Diodes Incorporated offers other devices with enhanced reliability and quality features, such as the AEC-Q100 qualified devices, which may be more suitable for these applications.
Diodes Incorporated recommends following the JEDEC J-STD-020D.1 standard for soldering profile, which specifies a peak temperature of 260°C (500°F) and a dwell time of 20-40 seconds. However, it's essential to consult the manufacturer's specific guidelines and ensure that the soldering process does not exceed the device's maximum ratings.
