Key Parameters

Substitute Part Grouping Explanation

Substitution of the HSMP-386B-TR2G is determined by the following critical parameters:

• Diode Type: PIN - Single configuration must be maintained
• Voltage Rating: Peak reverse voltage must meet or exceed 50V minimum
• Current Rating: Maximum current capacity must support 1 A minimum
• Capacitance Characteristics: Operating capacitance at specified frequency and voltage
• Resistance Characteristics: Forward resistance at specified current and frequency
• Operating Temperature Range: Junction temperature rating must accommodate 150°C minimum
• Package Compatibility: Physical form factor and pin configuration

The CLA4606-085LF meets these substitution criteria with enhanced electrical specifications and active product status.

Parameter Comparison

Engineering Selection Recommendations

The CLA4606-085LF is suitable as a substitute for the HSMP-386B-TR2G based on the following factors:

• Electrical Specifications: The substitute component exceeds the minimum voltage (75V vs. 50V), current (1.5 A vs. 1 A), and temperature (175°C vs. 150°C) requirements of the original part.
• Diode Configuration: Both components are PIN - Single diodes, maintaining functional equivalence.
• Product Status: The CLA4606-085LF is Active, ensuring ongoing availability and manufacturing support, whereas the HSMP-386B-TR2G is Obsolete.
• Compliance: Both components are REACH Unaffected and classified under ECCN EAR99, maintaining regulatory consistency.
• Moisture Sensitivity: Both components have MSL 1 (Unlimited), indicating equivalent handling requirements.

Package form factor differences (SOT-323 vs. 3-QFN) require physical layout verification during implementation.

Frequently Asked Questions (FAQ)

Q: Can the CLA4606-085LF directly replace the HSMP-386B-TR2G in existing designs?

A: Electrical substitution is valid based on the provided specifications. However, the package change from SOT-323 to 3-QFN (2x2) requires PCB layout modification and footprint redesign. Pin configuration and mechanical dimensions must be verified against the respective datasheets.

Q: Why does the CLA4606-085LF have higher capacitance than the HSMP-386B-TR2G?

A: Capacitance values are measured at different bias voltages and conditions (0.38pF @ 6V vs. 0.2pF @ 50V). Direct comparison requires measurement at identical conditions. The substitute's higher voltage rating and different measurement point account for the observed difference.

Q: Is the higher operating temperature of the CLA4606-085LF beneficial?

A: The 175°C junction temperature rating of the CLA4606-085LF provides additional thermal margin compared to the 150°C rating of the HSMP-386B-TR2G. This is advantageous for applications operating near maximum temperature limits.

Q: What are the implications of the current rating difference?

A: The CLA4606-085LF supports 1.5 A maximum current versus 1 A for the HSMP-386B-TR2G. This provides design margin and allows operation at higher current levels without exceeding component ratings.

Q: Are there any compliance or regulatory differences between these components?

A: Both components share identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS codes (8541.10.0080). No regulatory differences exist between the two parts.
