AGDT-4072

Overview

The AGDT-4072 is a surface-mount gate drive transformer manufactured by Allied Components International. It features a 1:1 turns ratio and provides 1500Vrms isolation voltage between primary and secondary windings. The component utilizes an SMD package with six pins, measuring 8.6mm by 7.4mm. It is designed for high-frequency signal transmission in power electronics applications.

Feature Summary

• Provides galvanic isolation for gate drive signals
• Supports high-frequency pulse transmission
• Compact surface-mount design for space-constrained PCBs

Applications

• Gate drive circuits for power MOSFETs and IGBTs
• Isolated DC-DC converter control loops
• High-side driver interfaces in motor drives

Procurement Notes

Verify the specific pinout configuration against the manufacturer's datasheet before integration. Confirm that the operating temperature range of -40°C to +85°C meets your environmental requirements. Ensure the 1500Vrms isolation rating is sufficient for your circuit's voltage stress levels. Check for RoHS compliance if required by your manufacturing standards.

Selection Notes

Select this component when isolated gate driving is required without optocouplers. Consider the 1:1 ratio for direct signal transfer. Evaluate the physical dimensions (8.6x7.4mm) against available board space. Compare propagation delay specifications if timing precision is critical for your switching frequency.

Part Context

Allied Components International specializes in magnetic components including inductors and transformers. The AGDT-4072 belongs to their series of surface-mount pulse transformers. These components are designed to replace bulky through-hole alternatives in modern power supply designs.

Replacement Considerations

Cross-reference with other 1:1 isolated gate drive transformers from manufacturers like Pulse Electronics or TDK. Verify equivalent isolation voltages and package footprints. Ensure similar frequency response characteristics to maintain signal integrity in existing designs.
