Vishay Series E Power MOSFET, 500V Drain Source Voltage, 19A Maximum Continuous Drain Current - SIHG20N50E-GE3


This power MOSFET is a high-voltage N-channel transistor designed for switching and power conversion in industrial and electrical systems. It operates in enhancement mode and is supplied in a through-hole TO-247 package, making it suitable for assemblies that require robust mounting and straightforward thermal management. The device supports high drain-source voltage and is intended for applications demanding elevated power handling and gate drive capabilities.

Features and Benefits:


• 500V maximum Vds enabling high-voltage switching capability
• 19 A continuous drain current for substantial load handling
• 184 mΩ Rds(on) for reduced conduction losses
• 46 nC typical gate charge allowing predictable drive requirements
• 179W maximum power dissipation for high thermal stress management
• 30V maximum gate-source voltage for wide gate‑drive compatibility

Applications


• Suitable for high-voltage DC-DC converters in power systems
• Ideal for industrial motor drive switching stages
• Used with power supplies for telecoms and infrastructure equipment
• Can be used for hard-switching topologies in inverters
• Suitable for laboratory and prototyping through-hole power designs

What temperature range can it reliably operate within?


The device is rated for a minimum ambient of -55 °C and a maximum operating temperature of 150 °C, accommodating a wide range of environmental conditions.

How does the package support mounting and heat removal?


The TO-247 through-hole package provides a large tab area for heatsinking and secure PCB or chassis mounting to facilitate thermal management in high-dissipation applications.

What gate‑drive limits should be observed during design?


Gate-source voltage must not exceed 30V to avoid gate oxide stress, and designers should size the driver to handle the typical 46 nC gate charge for controlled switching.

Are there considerations for switching losses with this device?


Designers should account for both the 184 mΩ conduction loss in the on-state and dynamic losses related to the 46 nC gate charge when calculating total switching energy.
