HER601-TP Equivalent & Substitute Parts

Part Overview

The HER601-TP is a general-purpose rectifier diode rated for 50 V DC reverse voltage and 6 A average rectified current, manufactured by Micro Commercial Co. This component features fast recovery characteristics with a reverse recovery time of 50 ns and is housed in an R-6 axial package for through-hole mounting applications.

The HER601-TP is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this rectifier diode.

Substitute Part Grouping Explanation

Substitution of the HER601-TP is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

Voltage - DC Reverse (Vr) (Max): Must equal or exceed 50 V
Current - Average Rectified (Io): Must equal or exceed 6 A
Mounting Type: Must be Through Hole
Operating Temperature Range: Must encompass or exceed -65°C to 150°C

Mechanical Compatibility Criteria:

Package / Case: Axial configuration for through-hole mounting

Compliance Requirements:

RoHS3 Compliance status must be maintained

The substitute part GI750-E3/73 meets all electrical requirements with identical voltage and current ratings. Both parts operate within compatible temperature ranges and maintain RoHS3 compliance. Package differences (R-6 versus P600) represent different axial package geometries; both are through-hole axial configurations suitable for PCB mounting in equivalent footprint applications.

Engineering Selection Recommendations

GI750-E3/73 as Primary Substitute:

The GI750-E3/73 is an active product from Vishay General Semiconductor - Diodes Division and serves as a direct electrical substitute for the obsolete HER601-TP. Both devices share identical voltage and current ratings (50 V, 6 A) and are housed in through-hole axial packages suitable for equivalent PCB mounting applications.

Key Considerations:

The GI750-E3/73 exhibits lower forward voltage drop (0.9 V versus 1.1 V at 6 A), resulting in reduced power dissipation in rectification applications. The substitute part operates with standard recovery characteristics (2.5 µs reverse recovery time) compared to the fast recovery specification of the original part (50 ns). This difference is significant only in high-frequency switching applications where fast recovery is a critical design requirement.

The GI750-E3/73 maintains a minimum operating temperature of -50°C, which is 15°C higher than the HER601-TP minimum of -65°C. Applications requiring operation below -50°C require evaluation of alternative substitutes.

Both parts maintain ROHS3 compliance and are available in active production status, ensuring long-term supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the GI750-E3/73 directly replace the HER601-TP in all applications?

A: The GI750-E3/73 is electrically compatible for voltage and current ratings. However, applications requiring fast recovery diode characteristics (trr ≤ 500 ns) must evaluate the performance impact of the GI750-E3/73 standard recovery specification (trr = 2.5 µs). Applications operating below -50°C require alternative substitutes due to the higher minimum junction temperature of the GI750-E3/73.

Q: What is the difference between the R-6 and P600 package types?

A: Both R-6 and P600 are through-hole axial package configurations. The designations represent different package geometries and lead spacing specifications from their respective manufacturers. Physical dimensions and PCB footprint requirements differ between these packages; mechanical verification is necessary for board-level integration.

Q: Are both parts RoHS compliant?

A: Yes. Both the HER601-TP and GI750-E3/73 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What is the significance of the forward voltage difference between these parts?

A: The HER601-TP specifies 1.1 V forward voltage drop at 6 A, while the GI750-E3/73 specifies 0.9 V at the same current. This 0.2 V difference results in lower power dissipation in the substitute part. For applications with tight thermal budgets or high-current continuous operation, this lower dissipation may provide thermal performance benefits.

Q: Why does the GI750-E3/73 have a higher reverse recovery time?

A: The HER601-TP is classified as a fast recovery diode (50 ns), while the GI750-E3/73 is a standard recovery diode (2.5 µs). Fast recovery diodes are optimized for high-frequency switching applications. Standard recovery diodes are suitable for line-frequency and low-frequency rectification. Application frequency requirements determine whether this difference is acceptable.
