Key Parameters

Substitute Part Grouping Explanation

Substitution of the HER602-TP is determined by strict equivalence across the following critical parameters:

• Voltage Rating: DC reverse voltage must equal or exceed 100 V
• Current Rating: Average rectified current must equal or exceed 6 A
• Package Type: R-6 axial through-hole configuration required for mechanical and electrical compatibility
• Forward Voltage: Maximum forward voltage drop at rated current
• Reverse Recovery Characteristics: Recovery speed classification and reverse leakage current
• Operating Temperature Range: Junction temperature capability
• Compliance Standards: RoHS3 compliance required for regulatory alignment

The substitute part 6A01B-G from Comchip Technology meets the core electrical and mechanical requirements for direct substitution, with the exception of recovery speed classification and maximum junction temperature, which represent functional differences requiring engineering evaluation.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 6A01B-G (Comchip Technology)

The 6A01B-G qualifies as a functional equivalent for the obsolete HER602-TP based on matching voltage and current ratings, identical package configuration, and equivalent reverse leakage and capacitance characteristics. Both components maintain ROHS3 compliance and operate within compatible temperature ranges for most applications.

Operational Differences Requiring Consideration:

The 6A01B-G operates with a maximum junction temperature of 125°C compared to the HER602-TP's 150°C rating. Applications requiring sustained operation above 125°C require thermal analysis to confirm the substitute's suitability.

The 6A01B-G is classified as standard recovery (>500ns) whereas the HER602-TP is fast recovery (≤500ns). Applications sensitive to reverse recovery time characteristics must evaluate whether standard recovery performance is acceptable for the intended circuit function.

The 6A01B-G exhibits a lower forward voltage drop (1.0 V versus 1.1 V at 6 A), resulting in reduced power dissipation and improved efficiency in rectification circuits.

The 6A01B-G maintains active product status with current manufacturing availability, eliminating obsolescence risk associated with the HER602-TP.

Frequently Asked Questions (FAQ)

Q: Can the 6A01B-G directly replace the HER602-TP in existing designs?

A: The 6A01B-G provides electrical and mechanical compatibility for most applications. Designs operating continuously above 125°C junction temperature or requiring fast recovery characteristics below 500ns must be re-evaluated. The lower forward voltage drop of the 6A01B-G may improve circuit efficiency but does not prevent direct substitution.

Q: What is the significance of the recovery speed difference?

A: The HER602-TP is classified as fast recovery with a 50 ns reverse recovery time, while the 6A01B-G is standard recovery with recovery time exceeding 500ns. Fast recovery diodes minimize switching losses in high-frequency applications. Standard recovery diodes are suitable for line-frequency and low-frequency rectification. Circuit performance depends on the operating frequency and switching characteristics required.

Q: Are both parts RoHS compliant?

A: Yes, both the HER602-TP and 6A01B-G are ROHS3 compliant, meeting regulatory requirements for hazardous substance restrictions.

Q: What is the maximum junction temperature difference between these parts?

A: The HER602-TP operates to 150°C junction temperature, while the 6A01B-G operates to 125°C. Applications with thermal designs targeting operation above 125°C require verification that the 6A01B-G remains within acceptable operating limits.

Q: Are the R-6 packages identical between manufacturers?

A: Both components use R-6 axial through-hole packages with identical mechanical dimensions and lead configurations, ensuring compatibility with existing printed circuit board layouts and assembly processes.

Q: Does the lower forward voltage of the 6A01B-G affect circuit operation?

A: The 6A01B-G forward voltage of 1.0 V at 6 A is 0.1 V lower than the HER602-TP. This reduces power dissipation and heat generation in rectification circuits. Voltage regulation circuits may require minor adjustment to account for the reduced voltage drop, but the difference is typically negligible in most applications.
