Product Description
Toroidal SMD Gate Drive Transformer with 4.5KVAC Isolation
Mission-Critical Switching Performance in Compact Form
Engineered for precision control of IGBT/MOSFET power modules, our SMD Transformer series leverages toroidal core technology to deliver superior magnetic coupling and minimal EMI radiation. With reinforced isolation meeting 4.5KVAC Isolated Transformer standards (tested at 60 seconds), it ensures safe operation in industrial motor drives and 800V EV battery systems. The surface-mount design saves 50% PCB space while supporting 5W output power at 65kHz—enabling robust switching without compromising reliability.

FAQ
Q: How does this differ from standard power transformers?
A: Designed specifically for Gate Drive Transformer applications:
  • Higher switching frequency (50-65kHz vs. 50/60Hz)
  • Lower leakage inductance (≤4μH vs. >100μH)
  • Reinforced isolation (4.5KVAC vs. 2.5KVAC typical)
Q: Can it eliminate shoot-through in half-bridge circuits?
A: Yes. The Toroidal SMD Transformer's tight coupling (±1.1% ratio tolerance) minimizes propagation delay skew. Combine with dead-time controllers for optimal results.
Q: Custom turn ratios supported?
A: Standard ratios 1:1.25/1.4/1.5/1.71 (GT09-001 to 004). Contact for custom windings.
