Key Parameters

Substitute Part Grouping Explanation

Substitution of the HER107S-AP with equivalent parts is determined by strict electrical and mechanical parameter matching within the rectifier diode category. The following parameters establish substitution eligibility:

Electrical Parameters (Critical):

• Voltage - DC Reverse (Vr) (Max): 800 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.7 V @ 1 A
• Reverse Recovery Time (trr): 75 ns
• Current - Reverse Leakage @ Vr: 5 mA @ 800 V
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Capacitance @ Vr, F: 15 pF @ 4V, 1MHz
• Operating Temperature - Junction: -55°C to 125°C

Mechanical Parameters (Critical):

• Mounting Type: Through Hole
• Package / Case: Axial or compatible axial variants

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Manufacturer: Micro Commercial Co
• Base Product Number: HER107

Substitute parts must match all electrical parameters and maintain through-hole axial mounting compatibility. Package variations within the axial family (A-405, DO-41, DO-204AL) are acceptable provided all electrical specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

The HER107G-AP is the direct equivalent substitute for the obsolete HER107S-AP. Both components are manufactured by Micro Commercial Co and share identical electrical specifications across all critical parameters: 800 V reverse voltage rating, 1 A average rectified current, 1.7 V forward voltage drop, and 75 ns reverse recovery time.

The HER107G-AP offers the following advantages for component selection:

Product Status: The HER107G-AP maintains active product status with Micro Commercial Co, ensuring continued availability and supply chain reliability. The HER107S-AP is classified as obsolete, making the HER107G-AP the appropriate long-term solution.

Compliance: Both parts maintain ROHS3 compliance and identical environmental operating temperature ranges (-55°C to 125°C). The HER107G-AP includes REACH Unaffected status, providing additional regulatory documentation.

Reverse Leakage Current: The HER107G-AP demonstrates superior reverse leakage performance at 5 µA @ 800 V compared to the main part specification of 5 mA @ 800 V, indicating improved device quality and lower standby current characteristics.

Package Compatibility: While the HER107S-AP uses the A-405 package and the HER107G-AP uses the DO-41 package, both are axial through-hole configurations with identical electrical performance. PCB layout and mechanical mounting accommodate standard axial diode footprints.

Inventory Availability: The HER107G-AP is available in active inventory (956 Pcs New Original In Stock), supporting immediate procurement for production requirements.

Frequently Asked Questions (FAQ)

Q: Can the HER107G-AP directly replace the HER107S-AP in existing designs?

A: Yes. The HER107G-AP is electrically identical to the HER107S-AP across all specified parameters. Both components share the same voltage rating (800 V), current rating (1 A), forward voltage drop (1.7 V @ 1 A), and reverse recovery time (75 ns). Through-hole axial mounting is compatible with standard PCB layouts designed for either package variant.

Q: What is the difference between the A-405 and DO-41 packages?

A: Both A-405 and DO-41 are axial through-hole package designations for rectifier diodes. The DO-41 designation (DO-204AL) is the industry-standard package code. Both packages accommodate identical lead spacing and mounting hole requirements for through-hole PCB assembly. Package selection does not affect electrical performance.

Q: Why does the HER107G-AP show lower reverse leakage current (5 µA) compared to the HER107S-AP (5 mA)?

A: The HER107G-AP demonstrates improved reverse leakage characteristics at 5 µA @ 800 V, which represents superior device quality and lower standby current consumption. This improvement does not affect substitution eligibility; it indicates the substitute part offers enhanced performance in this parameter.

Q: Is the HER107G-AP suitable for high-frequency switching applications?

A: Both the HER107S-AP and HER107G-AP are classified as fast recovery diodes with a reverse recovery time of 75 ns and speed classification of Fast Recovery ≤ 500ns, > 200mA (Io). This specification supports switching applications within the stated current and voltage ratings.

Q: What compliance certifications apply to the HER107G-AP?

A: The HER107G-AP is ROHS3 compliant and REACH unaffected. Both certifications are current and applicable for new production builds and procurement. The component maintains EAR99 export classification and HTSUS code 8541.10.0080.

Q: Are there any thermal considerations when substituting the HER107G-AP for the HER107S-AP?

A: Both components share identical operating temperature specifications (-55°C to 125°C junction temperature range). Thermal management requirements remain unchanged. Forward voltage drop (1.7 V @ 1 A) and reverse leakage characteristics are identical or superior in the substitute part, resulting in equivalent or reduced thermal dissipation.

Q: What is the moisture sensitivity level for the HER107G-AP?

A: The HER107G-AP carries MSL 1 (Unlimited) moisture sensitivity level, indicating no moisture-related handling restrictions during storage, transport, or assembly. This matches the HER107S-AP specification.
