IHV15BZ500 - Vishay

IHV15BZ500 Frequently Asked Questions (FAQs)

• What is the recommended PCB footprint for the IHV15BZ500?
  The recommended PCB footprint for the IHV15BZ500 is a rectangular pad with dimensions of 5.08 mm x 3.81 mm, with a thermal pad of 2.54 mm x 2.54 mm in the center. The pad should have a solder mask defined (SMD) and a non-solder mask defined (NSMD) area around the thermal pad.
• How do I ensure reliable soldering of the IHV15BZ500?
  To ensure reliable soldering, use a soldering iron with a temperature range of 250°C to 260°C, and a solder with a melting point of 217°C to 220°C. Apply a small amount of solder paste to the PCB pads, and use a reflow oven or a hot air soldering station to solder the component. Avoid using excessive solder or flux, as it can cause shorts or damage to the component.
• What is the maximum allowed voltage derating for the IHV15BZ500?
  The maximum allowed voltage derating for the IHV15BZ500 is 80% of the rated voltage, which is 400 V. This means that the maximum allowed voltage is 320 V. Exceeding this voltage can reduce the component's lifespan or cause it to fail prematurely.
• How do I calculate the power dissipation of the IHV15BZ500?
  To calculate the power dissipation of the IHV15BZ500, use the following formula: Pd = (Vds x Ids) / Rth, where Pd is the power dissipation, Vds is the drain-to-source voltage, Ids is the drain current, and Rth is the thermal resistance. The thermal resistance (Rth) is typically specified in the datasheet as 1.5°C/W for the IHV15BZ500.
• What is the recommended thermal management for the IHV15BZ500?
  The recommended thermal management for the IHV15BZ500 includes using a heat sink with a thermal interface material (TIM) to reduce the thermal resistance between the component and the heat sink. The heat sink should be designed to provide adequate airflow and heat dissipation. Additionally, ensure that the PCB is designed to provide a good thermal path to the heat sink.
