HER508GP-AP Equivalent & Substitute Parts

Part Overview

The HER508GP-AP is a fast recovery rectifier diode manufactured by Micro Commercial Co, rated for 1000 V DC reverse voltage and 5 A average rectified current in a through-hole DO-201AD axial package. This component is classified as Active product status and utilizes standard rectifier technology with a reverse recovery time of 75 ns, making it suitable for high-speed switching applications requiring fast recovery characteristics.

Substitute parts are identified when equivalent electrical performance can be maintained within the specified parameter tolerances while maintaining identical or compatible mechanical packaging. The HER508GP-AP has one identified substitute based on matching voltage rating, package type, and mounting configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HER508GP-AP is determined by the following critical parameters:

Mandatory Matching Criteria:

• Voltage - DC Reverse (Vr) (Max): 1000 V
• Package / Case: DO-201AD, Axial
• Mounting Type: Through Hole

Allowable Parameter Variations:

• Current - Average Rectified (Io): Substitute must equal or exceed the main part rating
• Reverse Recovery Time (trr): Substitute may have longer recovery time if application permits
• Operating Temperature Range: Substitute must cover the required operating window

The identified substitute GI510-E3/54 matches the mandatory voltage and package criteria. However, the current rating differs at 3 A versus 5 A on the main part, which represents a derating condition. This substitute is applicable only in applications where the circuit current requirement does not exceed 3 A.

Engineering Selection Recommendations

HER508GP-AP Selection Criteria:

• Applications requiring 5 A average rectified current capacity
• Fast recovery switching applications with trr ≤ 75 ns requirement
• Operating environments with minimum junction temperature of -65°C
• Bulk packaging availability for high-volume procurement

GI510-E3/54 Selection Criteria:

• Applications with maximum current requirement of 3 A
• Standard recovery speed applications where trr ≤ 2 µs is acceptable
• Operating environments with minimum junction temperature of -50°C
• Cut tape packaging suitable for automated assembly processes
• RoHS3 compliance requirement
• Moisture sensitivity level 1 (unlimited shelf life)

Both parts maintain Active product status and REACH Unaffected compliance. The GI510-E3/54 provides additional RoHS3 certification and superior moisture sensitivity rating. Selection between these parts depends on circuit current requirements and recovery speed specifications.

Frequently Asked Questions (FAQ)

Q: Can GI510-E3/54 replace HER508GP-AP in all applications?

A: No. The GI510-E3/54 is rated for 3 A average rectified current, while the HER508GP-AP is rated for 5 A. Substitution is valid only when circuit current does not exceed 3 A. Additionally, the GI510-E3/54 has a reverse recovery time of 2 µs compared to 75 ns for the HER508GP-AP, making it unsuitable for applications requiring fast recovery characteristics.

Q: Are the packages physically identical?

A: Yes. Both parts use the DO-201AD axial through-hole package. Physical dimensions and PCB footprints are identical, allowing direct mechanical substitution without layout modifications.

Q: What is the difference in forward voltage drop?

A: The HER508GP-AP specifies 1.7 V maximum forward voltage at 5 A, while the GI510-E3/54 specifies 1.1 V maximum at 9.4 A. Forward voltage characteristics differ between the parts due to different semiconductor designs and current ratings. Direct comparison requires evaluation at identical current levels.

Q: Does operating temperature range affect substitution?

A: The HER508GP-AP operates from -65°C to 150°C, while the GI510-E3/54 operates from -50°C to 150°C. If the application requires operation below -50°C, the GI510-E3/54 is not suitable.

Q: What packaging format differences exist?

A: The HER508GP-AP is supplied in Bulk packaging, while the GI510-E3/54 is supplied in Cut Tape (CT) packaging. This affects procurement, handling, and assembly processes but does not impact electrical performance or mechanical compatibility.

Q: Are both parts compliant with environmental regulations?

A: Both parts are REACH Unaffected and carry EAR99 ECCN classification. The GI510-E3/54 additionally meets RoHS3 compliance requirements. Verify specific regulatory requirements for your application and region.
