MGDT100100

Pulse Transformers Overview

The MGDT100100 is a planar gate-drive pulse transformer manufactured by Vishay Dale. It features a primary-to-secondary turns ratio of 1:1:1 and an inductance of 240µH. Designed for surface-mount installation, the component measures 20.57mm in length, 18.42mm in width, and has a maximum height of 11.43mm. It operates within a temperature range of -55°C to +125°C and complies with RoHS3 standards.

Pulse Transformers Feature Summary

• Planar construction optimized for high-frequency gate drive applications
• Dual isolated secondary windings providing galvanic isolation
• Surface-mount package design for automated PCB assembly

Pulse Transformers Applications

• High-side MOSFET gate driving
• IGBT gate drive circuits
• Isolated power supply control loops

Pulse Transformers Procurement Notes

Verify the specific suffix designation when ordering, as variants such as -SM indicate surface-mount packaging while other suffixes may denote through-hole configurations. Confirm that the required turns ratio matches the 1:1:1 specification for the target circuit topology. Ensure the selected variant aligns with the intended mounting method and thermal management requirements of the final assembly.

Pulse Transformers Selection Notes

Select this component when a 1:1:1 isolation ratio is required for synchronous rectification or half-bridge topologies. The 240µH inductance supports standard switching frequencies typical in industrial power converters. Evaluate the physical dimensions against the available PCB real estate, noting the 11.43mm height constraint. Consider thermal performance at the upper limit of the 125°C operating range.

Pulse Transformers Part Context

This part belongs to the MGDT series of planar gate-drive transformers from Vishay Dale. The series provides various turns ratios and mounting options to accommodate different isolated drive requirements. The MGDT100100 specifically addresses applications requiring symmetric voltage transfer between primary and dual secondary windings.

Pulse Transformers Replacement Considerations

Cross-reference with MGDT100100-SM for identical electrical specifications but confirmed surface-mount availability. Verify mechanical footprint compatibility if substituting with non-Vishay equivalents, as planar transformer pinouts and heights vary significantly across manufacturers.
