IX3180GS Equivalent & Substitute Parts

Part Overview

The IX3180GS is a 3.75kV optical isolation gate driver manufactured by IXYS Integrated Circuits Division, designed for single-channel gate drive applications requiring high-voltage isolation. This component integrates a 2.5A peak output current capability with 10kV/µs common mode transient immunity in an 8-SMD surface mount package. The product is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IX3180GS is determined by strict equivalence across the following critical parameters:

• Isolation voltage rating of 3750Vrms
• Single-channel gate driver configuration
• Peak output current of 2.5A with 2A continuous output capability
• Common mode transient immunity of 10kV/µs minimum
• Propagation delay specifications of 200ns maximum for both rising and falling edges
• Pulse width distortion not exceeding 65ns
• Output supply voltage range of 10V to 20V
• Operating temperature range of -40°C to 100°C
• RoHS3 compliance and REACH unaffected status

The HCPL-3180-300E from Broadcom Limited meets all specified electrical and functional parameters required for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-3180-300E is the qualified substitute for the obsolete IX3180GS. Both components maintain identical electrical specifications across all critical gate driver parameters. The HCPL-3180-300E carries active product status with established supply availability, whereas the IX3180GS is obsolete. Both components satisfy ROHS3 compliance and REACH unaffected requirements, meeting current regulatory standards for electronic component procurement.

The primary difference between these parts is packaging format: the IX3180GS uses 8-SMD Gull Wing configuration, while the HCPL-3180-300E is supplied in 8-DIP Gull Wing format. This packaging distinction requires PCB layout modification but does not affect electrical performance or functional compatibility in gate driver applications.

Frequently Asked Questions (FAQ)

Q: Can the HCPL-3180-300E directly replace the IX3180GS without circuit modification?

A: Electrical substitution is complete. However, the package format differs (8-SMD versus 8-DIP Gull Wing), requiring PCB footprint redesign. Pin functionality and electrical specifications are identical.

Q: What is the primary reason for substituting the IX3180GS?

A: The IX3180GS is obsolete. The HCPL-3180-300E provides equivalent electrical performance with active product status and established supply chain availability.

Q: Are there any compliance differences between these parts?

A: Both components are ROHS3 compliant and REACH unaffected. The HCPL-3180-300E carries additional CSA approval in addition to UR certification.

Q: How do the forward voltage and forward current specifications differ?

A: The IX3180GS specifies Vf of 1.35V at 20mA maximum forward current. The HCPL-3180-300E specifies Vf of 1.5V at 25mA maximum forward current. These differences are within normal component variation and do not affect gate driver functionality.

Q: Is the HCPL-3180-300E suitable for the same temperature range applications?

A: Yes. Both components operate across the identical temperature range of -40°C to 100°C.
