Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HSMP-386C-TR1G is determined by the following critical parameters:

• Diode Type: Must be PIN - 1 Pair Series Connection configuration
• Voltage Rating: Peak reverse voltage must be rated at or above 50V
• Package: Must be SC-70/SOT-323 form factor for mechanical compatibility
• Operating Temperature: Must support 150°C (TJ) maximum junction temperature
• Moisture Sensitivity: MSL rating of 1 or better

The RN779FFHT106 manufactured by Rohm Semiconductor meets these core substitution criteria. Both parts share identical diode topology, voltage rating, package form factor, temperature rating, and MSL classification.

Parameter Comparison

Engineering Selection Recommendations

The RN779FFHT106 is an active product with ROHS3 compliance and AEC-Q101 automotive qualification, providing long-term availability and regulatory alignment compared to the obsolete HSMP-386C-TR1G. Both parts maintain identical voltage ratings, package form factors, and operating temperature specifications.

The RN779FFHT106 carries a lower maximum current rating of 50 mA versus the HSMP-386C-TR1G at 1 A. Circuit designs operating at currents exceeding 50 mA require verification that the substitute part meets application requirements. The RN779FFHT106 exhibits higher capacitance and resistance characteristics; applications sensitive to these parameters must confirm compatibility with measured values at specified bias conditions.

Frequently Asked Questions (FAQ)

Q: Can the RN779FFHT106 directly replace the HSMP-386C-TR1G in all applications?

A: Both parts share identical diode topology, voltage rating, package form factor, and operating temperature. However, the RN779FFHT106 has a maximum current rating of 50 mA compared to 1 A for the HSMP-386C-TR1G. Applications requiring currents above 50 mA cannot use this substitute.

Q: Are there package compatibility concerns between these parts?

A: Both parts use SC-70/SOT-323 packaging. Mechanical and electrical footprints are compatible for PCB assembly.

Q: What is the significance of the product status difference?

A: The HSMP-386C-TR1G is classified as Obsolete, indicating discontinued manufacturing. The RN779FFHT106 is Active, ensuring ongoing availability and manufacturing support.

Q: Does the RN779FFHT106 meet automotive standards?

A: Yes, the RN779FFHT106 carries AEC-Q101 qualification and ROHS3 compliance, suitable for automotive applications.

Q: How do the capacitance and resistance differences affect circuit performance?

A: The RN779FFHT106 exhibits 0.9pF capacitance at 35V (versus 0.2pF at 50V for the original) and 7Ohm resistance at 10mA (versus 1.5Ohm at 100mA for the original). Circuit designs dependent on these specific electrical characteristics require validation against the substitute part's measured parameters.
