ZA9368-AED

Overview

The Coilcraft ZA9368-AED is an encapsulated pulse transformer designed for isolation and data interface applications. It features a 1:1.75 turns ratio and a primary inductance of 256µH, measured at 10 kHz with 0.01 Vrms excitation. The component supports surface mount assembly with a maximum standing height of 5.60mm. It operates within a temperature range of -40°C to 125°C. The device is rated for a maximum output current of 700 mA, which results in a 40°C temperature rise from ambient conditions.

Feature Summary

• Encapsulated construction for robust isolation and data interface performance
• Optimized specifically for Texas Instruments SN6505 transformer driver circuits
• Halogen-free composition compliant with RoHS standards

Applications

• Isolation barriers in power supply circuits utilizing the SN6505 driver
• Data interface isolation requiring specific voltage transformation ratios
• Surface mount assembly in compact electronic devices

Procurement Notes

Verify that the ordering suffix 'AED' corresponds to the required tape and reel packaging configuration rather than bulk quantities. Confirm that the halogen-free status meets specific environmental compliance requirements for the target application. Ensure the operating temperature range aligns with the thermal profile of the final assembly environment.

Selection Notes

Select this component when integrating with the Texas Instruments SN6505 transformer driver IC. The 1:1.75 turns ratio must match the voltage step-up requirements of the secondary circuit. Verify that the 256µH primary inductance is sufficient for the intended switching frequency to prevent saturation. Ensure the physical footprint accommodates the 5.60mm maximum height constraint.

Part Context

This part belongs to the Coilcraft ZA9368 series of power transformers. These components are engineered for high-frequency operation in isolated power conversion topologies. The series provides various turns ratios to accommodate different input and output voltage configurations while maintaining electrical isolation between primary and secondary sides.

Replacement Considerations

Direct substitutes within the same family include other ZA9368 variants with different turns ratios or packaging options. Cross-referencing requires matching the 1:1.75 ratio and SN6505 compatibility. Alternative manufacturers may offer similar pulse transformers but require verification of inductance and thermal characteristics.
