HER106S-AP Equivalent & Substitute Parts

Part Overview

The HER106S-AP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 600V DC reverse voltage and 1A average rectified current. This component features fast recovery characteristics with a reverse recovery time of 75 nanoseconds, making it suitable for standard rectification applications requiring rapid switching performance. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional compatibility within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HER106S-AP is determined by the following critical parameters:

Voltage Rating: All substitute parts must maintain a DC reverse voltage rating of 600V or greater to ensure equivalent voltage withstand capability.

Current Rating: Substitute parts must support the 1A average rectified current requirement. Parts with equal or higher current ratings are acceptable.

Package Type: All substitutes must use axial through-hole packaging to maintain mechanical compatibility with existing circuit board layouts and assembly processes.

Mounting Configuration: Through-hole mounting is mandatory for direct replacement without circuit redesign.

Compliance Standards: Active product status and RoHS compliance are required for new designs and procurement.

The identified substitute parts meet these core substitution criteria while offering active product status and improved availability compared to the obsolete HER106S-AP.

Parameter Comparison

Engineering Selection Recommendations

EM 2AV is suitable for applications where the 1A current requirement can be satisfied by a 1.2A rated component. This part offers active product status and improved availability. The EM 2AV provides superior reverse leakage characteristics (10 µA versus 5 mA) and lower forward voltage drop (920 mV versus 1.3 V), resulting in reduced power dissipation. The extended operating temperature range (-40°C to 150°C) accommodates broader environmental conditions compared to the original part. Standard recovery speed classification indicates this part is appropriate for general-purpose rectification where fast recovery is not a circuit requirement.

ES01AV1 is applicable only in circuits where the 700mA current rating meets system requirements. This part is not suitable as a direct replacement for 1A applications. The ES01AV1 exhibits significantly higher forward voltage (3 V @ 800 mA) and substantially longer reverse recovery time (1.5 µs), making it unsuitable for high-frequency switching applications. Selection of this part requires confirmation that circuit current demands do not exceed 700mA.

Both substitute parts maintain 600V voltage rating, axial through-hole packaging, and RoHS compliance, ensuring mechanical and regulatory compatibility with the original HER106S-AP specification.

Frequently Asked Questions (FAQ)

Q: Can EM 2AV directly replace HER106S-AP in all applications?

A: EM 2AV meets the core substitution criteria of 600V voltage rating, 1A minimum current capacity, and axial through-hole packaging. The higher current rating (1.2A) and improved reverse leakage characteristics make it functionally compatible. However, the transition from fast recovery to standard recovery speed classification requires verification that the application does not depend on the 75ns reverse recovery time of the original part.

Q: Is ES01AV1 a suitable replacement for HER106S-AP?

A: ES01AV1 is not recommended as a direct replacement due to its 700mA current rating, which falls below the 1A requirement of the original part. This part is only applicable in circuits confirmed to operate at 700mA or lower current levels.

Q: What are the packaging differences between the substitute parts?

A: All three parts use axial through-hole packaging and are mechanically compatible. EM 2AV is supplied in Tape & Reel format, while ES01AV1 is supplied in Tape & Box format. Both packaging formats are suitable for through-hole assembly without modification to existing circuit board designs.

Q: How do the operating temperature ranges compare?

A: HER106S-AP operates from -55°C to 125°C. Both substitute parts extend the upper temperature limit to 150°C and raise the lower limit to -40°C. Applications requiring operation below -40°C cannot use the substitute parts.

Q: What is the significance of reverse recovery time differences?

A: HER106S-AP features fast recovery at 75 nanoseconds, while EM 2AV is classified as standard recovery (>500ns) and ES01AV1 specifies 1.5 microseconds. Fast recovery is critical in high-frequency switching applications. Standard recovery parts are suitable for line-frequency and low-frequency rectification where switching speed is not a limiting factor.

Q: Are the substitute parts RoHS compliant?

A: Yes, both EM 2AV and ES01AV1 are RoHS compliant, meeting regulatory requirements for new designs and procurement in restricted substance directives.
