IX3120GSTR Equivalent & Substitute Parts

Part Overview

The IX3120GSTR is a 2.5A gate driver optical coupler manufactured by IXYS Integrated Circuits Division, providing 3750Vrms isolation for single-channel gate drive applications. This component integrates optical coupling technology to deliver galvanic isolation in high-voltage switching circuits, with common mode transient immunity of 25kV/µs and propagation delay specifications of 500ns maximum.

The IX3120GSTR carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IX3120GSTR is determined by the following critical parameters:

• Voltage isolation rating: 3750Vrms minimum
• Single-channel gate driver configuration
• Common mode transient immunity: 25kV/µs minimum
• Propagation delay: 500ns maximum (tpLH and tpHL)
• Pulse width distortion: 300ns maximum
• Output current capability: 2A minimum (high and low), 2.5A peak
• Output supply voltage range: 15V to 30V
• Operating temperature range: -40°C to 100°C minimum
• Optical coupling technology
• Surface mount package with gull wing configuration

The HCPL-3120-500E from Broadcom Limited meets all specified electrical and mechanical parameters, maintaining functional equivalence across isolation voltage, channel count, timing specifications, current ratings, and operating conditions. The substitute part is manufactured by an established supplier with active product status and full compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-3120-500E is the qualified substitute for the obsolete IX3120GSTR. Both components maintain identical electrical specifications across all critical gate driver parameters, including isolation voltage, propagation delay, pulse width distortion, and output current ratings. The substitute part carries active product status, ensuring long-term availability and supply chain stability.

The HCPL-3120-500E holds ROHS3 compliance equivalent to the original part and carries additional CSA approval certification alongside UR approval. Both components are REACH unaffected and carry EAR99 ECCN classification. The substitute part is available in higher inventory quantities, supporting production continuity.

Frequently Asked Questions (FAQ)

Q: Can the HCPL-3120-500E directly replace the IX3120GSTR in existing designs?

A: Yes. Both components share identical electrical specifications for isolation voltage (3750Vrms), propagation delay (500ns maximum), pulse width distortion (300ns maximum), output current ratings (2A/2A, 2.5A peak), and operating temperature range (-40°C to 100°C). The package configuration (8-SMD, Gull Wing) and surface mount mounting type are identical, enabling direct substitution without circuit modification.

Q: What is the primary difference between these two parts?

A: The IX3120GSTR is obsolete, while the HCPL-3120-500E maintains active product status. The substitute part is manufactured by Broadcom Limited and carries CSA approval in addition to UR approval. All functional and electrical parameters remain equivalent.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification. The HCPL-3120-500E includes CSA certification in addition to UR approval, providing broader regulatory coverage.

Q: Does the substitute part require any PCB layout modifications?

A: No. Both components use identical 8-SMD Gull Wing packaging, maintaining the same footprint, pin configuration, and surface mount requirements. Existing PCB designs require no modification.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution is determined by matching isolation voltage (3750Vrms), single-channel configuration, common mode transient immunity (25kV/µs), propagation delay (500ns maximum), pulse width distortion (300ns maximum), output current capability (2A/2A, 2.5A peak), and output supply voltage range (15V to 30V).
