Key Parameters

Substitute Part Grouping Explanation

Substitution of the HSMP-482B-TR2G is determined by the following electrical and mechanical criteria:

• Diode Type: Must be PIN - Single configuration
• Voltage Rating: Peak reverse voltage must equal or exceed 50V
• Current Rating: Maximum current must equal or exceed 1 A
• Package Compatibility: Physical form factor must accommodate the application's space and thermal constraints
• Product Status: Active status preferred for long-term availability

The two substitute parts listed below meet these criteria with enhanced electrical performance characteristics:

• CLA4605-085LF: 60V rating, 1.5 A current, improved capacitance and resistance performance, Active status
• CLA4608-085LF: 180V rating, 1.5 A current, enhanced power dissipation capability, Active status

Both substitutes are manufactured by Skyworks Solutions Inc. and feature improved thermal performance (175°C operating temperature) compared to the original part.

Parameter Comparison

Engineering Selection Recommendations

CLA4605-085LF is suitable for applications requiring voltage ratings between 50V and 60V with current demands up to 1.5 A. This part offers improved capacitance performance and reduced moisture sensitivity compared to the HSMP-482B-TR2G. Active product status ensures long-term availability and supply chain continuity. ROHS3 compliance supports environmental and regulatory requirements.

CLA4608-085LF is appropriate for applications requiring higher voltage ratings up to 180V or enhanced power dissipation capability (2 W maximum). This part provides the highest voltage margin and is suitable for circuits operating at elevated reverse bias conditions. Active product status and ROHS3 compliance provide equivalent regulatory support.

Both substitute parts feature improved operating temperature ratings (175°C versus 150°C) and unlimited moisture sensitivity levels, reducing handling and storage constraints compared to the original part.

Frequently Asked Questions (FAQ)

Q: Can CLA4605-085LF or CLA4608-085LF be used as direct replacements for HSMP-482B-TR2G?

A: Both parts meet the minimum electrical requirements (voltage, current, and diode type) for substitution. However, package differences must be evaluated. The HSMP-482B-TR2G uses SOT-323 packaging, while both substitutes use 3-QFN (2x2) packaging. PCB layout and footprint modifications are required.

Q: What are the key differences between CLA4605-085LF and CLA4608-085LF?

A: The primary differences are voltage rating (60V versus 180V) and power dissipation capability (1 W versus 2 W). CLA4608-085LF provides higher voltage margin and greater power handling. Selection depends on circuit operating conditions and voltage stress requirements.

Q: Are there any compliance or regulatory differences?

A: Both substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of the original part. Both feature improved moisture sensitivity levels (MSL 1 versus MSL 2A), reducing handling constraints.

Q: How do the RF characteristics compare?

A: Capacitance and resistance values differ across the three parts due to different measurement conditions and device geometries. Circuit performance must be evaluated based on specific application requirements and operating frequencies.
