HER152-TP Equivalent & Substitute Parts

Part Overview

The HER152-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 100 V DC reverse voltage and 1.5 A average rectified current in a DO-15 through-hole package. This component is classified as obsolete, making identification of equivalent and substitute parts necessary for ongoing design support, maintenance, and production continuity. Substitute parts must maintain electrical compatibility across voltage, current, and thermal specifications while accommodating the through-hole axial package format.

Substitute Part Grouping Explanation

Substitute parts for the HER152-TP are selected based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

Voltage Rating: All substitute parts must maintain a minimum DC reverse voltage rating of 100 V to ensure safe operation in the original circuit application.

Current Rating: Substitute parts rated at 1.5 A or higher satisfy the average rectified current requirement. Parts with higher current ratings (such as 2 A) provide additional design margin and are electrically compatible.

Package Format: All substitute parts must use through-hole axial mounting in DO-15 or DO-204AC package designations to ensure mechanical fit and circuit board compatibility.

Reverse Leakage: Substitute parts with reverse leakage current of 5 µA or lower at 100 V maintain functional equivalence in applications sensitive to leakage characteristics.

Operating Temperature Range: Substitute parts with operating temperature ranges that encompass or exceed the original -55°C to 125°C specification ensure thermal compatibility.

The two substitute parts listed below meet these criteria and are available in active product status, providing long-term supply assurance compared to the obsolete HER152-TP.

Engineering Selection Recommendations

1N5392GHB0G Selection Criteria:

The 1N5392GHB0G is a direct electrical equivalent to the HER152-TP, matching the 100 V / 1.5 A rating specification. This part is manufactured by Taiwan Semiconductor Corporation and maintains active product status, ensuring long-term availability and supply chain stability. The component is ROHS3 compliant and carries AEC-Q101 automotive qualification, providing additional quality assurance for applications requiring automotive-grade reliability. The extended operating temperature range (-55°C to 150°C) exceeds the original specification, offering improved thermal margin. Forward voltage is slightly elevated at 1.1 V compared to 1 V, which is acceptable for general-purpose rectification applications. This part is the preferred direct replacement for the obsolete HER152-TP.

2A02G A0G Selection Criteria:

The 2A02G A0G provides a higher current rating of 2 A while maintaining the same 100 V voltage specification. This part is suitable for applications where the original circuit can tolerate increased current capacity without adverse effects. The higher current rating provides design margin for circuits operating near the 1.5 A limit of the original part. Like the 1N5392GHB0G, this part is active, ROHS3 compliant, and offers an extended operating temperature range. Selection of this part should be based on circuit analysis confirming that the higher current rating does not introduce unintended circuit behavior. Both substitute parts are available in identical through-hole axial packaging, ensuring mechanical compatibility with existing circuit board layouts.

Frequently Asked Questions (FAQ)

Q: Can the 1N5392GHB0G be used as a direct replacement for the HER152-TP?

A: Yes. The 1N5392GHB0G matches the HER152-TP in voltage rating (100 V), current rating (1.5 A), reverse leakage (5 µA @ 100 V), and package format (DO-15 axial through-hole). The forward voltage is 1.1 V compared to 1 V, which is within acceptable tolerance for general-purpose rectification. The extended operating temperature range provides additional thermal margin.

Q: What is the difference between the 1N5392GHB0G and 2A02G A0G?

A: The primary difference is current rating. The 1N5392GHB0G is rated for 1.5 A average rectified current, matching the original HER152-TP specification. The 2A02G A0G is rated for 2 A, providing 33% additional current capacity. Both parts maintain the same 100 V voltage rating and identical package format. Selection between these parts depends on circuit current requirements and design margin considerations.

Q: Are these substitute parts compatible with the original circuit board layout?

A: Yes. Both substitute parts use DO-15 axial through-hole packaging, which is mechanically identical to the original HER152-TP package. No circuit board modifications are required for component substitution.

Q: What is the significance of the AEC-Q101 qualification on the 1N5392GHB0G?

A: AEC-Q101 is an automotive industry qualification standard for discrete semiconductors. This certification indicates that the 1N5392GHB0G has undergone rigorous testing and quality validation for automotive applications. This qualification is not present on the 2A02G A0G and may be relevant for applications requiring automotive-grade component reliability.

Q: Can the 2A02G A0G be used in place of the 1N5392GHB0G?

A: Yes, from an electrical standpoint. The 2A02G A0G maintains the same 100 V voltage rating and package format while providing higher current capacity. However, circuit analysis should confirm that the higher current rating does not introduce unintended circuit behavior, such as altered rectification characteristics or thermal effects in the application.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The HER152-TP, 1N5392GHB0G, and 2A02G A0G are all ROHS3 compliant, ensuring compatibility with environmental and regulatory requirements for lead-free electronics manufacturing.

Q: What is the operating temperature range difference between the original and substitute parts?

A: The HER152-TP operates from -55°C to 125°C. Both substitute parts extend the upper limit to 150°C, providing an additional 25°C of thermal margin. This extended range is beneficial for applications operating in elevated temperature environments.
