MURD620CTH Equivalent & Substitute Parts

Part Overview

The MURD620CTH is a general-purpose diode array manufactured by onsemi, configured as a 1 Pair Common Cathode rectifier with a maximum reverse voltage rating of 200 V and average rectified current of 3 A per diode. The device is housed in a Surface Mount TO-252-3 DPAK package with 2 leads plus tab (SC-63).

This part is classified as Obsolete. Locating equivalent or substitute components becomes necessary when the original part reaches end-of-life status, inventory depletion occurs, or supply chain discontinuation is announced. Substitute parts must maintain electrical and mechanical compatibility to ensure direct replacement capability in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MURD620CTH is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Diode Configuration: 1 Pair Common Cathode (pin-for-pin compatibility)
• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63 (mechanical fit and thermal characteristics)
• Voltage - DC Reverse (Vr) (Max): 200 V (minimum voltage rating requirement)
• Operating Temperature - Junction: -65°C ~ 175°C (thermal operating range)
• Mounting Type: Surface Mount (assembly process compatibility)

Performance Parameters (Allowable Variation):

• Current - Average Rectified (Io): Substitute must equal or exceed 3 A per diode
• Voltage - Forward (Vf): Substitute specifications must be documented
• Reverse Recovery Time (trr): Substitute specifications must be documented
• Current - Reverse Leakage @ Vr: Substitute specifications must be documented

The VS-MURD620CT-M3 satisfies all mandatory compatibility criteria and exceeds the current rating requirement, making it a valid substitute for the MURD620CTH.

Parameter Comparison

Engineering Selection Recommendations

The VS-MURD620CT-M3 manufactured by Vishay General Semiconductor - Diodes Division is a qualified substitute for the MURD620CTH. Selection is based on the following engineering factors:

Compliance and Regulatory Status: Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment with current environmental and hazardous substance directives.

Product Lifecycle Status: The MURD620CTH is classified as Obsolete, while the VS-MURD620CT-M3 maintains Active product status. Active status ensures continued availability, technical support, and supply chain reliability for new designs and production runs.

Electrical and Mechanical Compatibility: The substitute part maintains identical diode configuration (1 Pair Common Cathode), reverse voltage rating (200 V), operating temperature range (-65°C ~ 175°C), and package form factor (TO-252-3 DPAK SC-63). These parameters ensure direct pin-for-pin and mechanical compatibility without circuit redesign.

Performance Enhancement: The VS-MURD620CT-M3 provides increased current capacity (6 A versus 3 A per diode) and improved reverse recovery time (19 ns versus 35 ns), delivering superior performance characteristics within the same package envelope.

Packaging and Handling: The substitute part is supplied in Tube packaging with Moisture Sensitivity Level (MSL) 1 (Unlimited), compared to the original part's vendor-undefined MSL specification. This provides enhanced handling flexibility and extended shelf life.

Frequently Asked Questions (FAQ)

Q: Can the VS-MURD620CT-M3 be used as a direct replacement for the MURD620CTH in existing circuit designs?

A: Yes. Both parts share identical diode configuration (1 Pair Common Cathode), reverse voltage rating (200 V), operating temperature range (-65°C ~ 175°C), and TO-252-3 DPAK package form factor. Pin-for-pin and mechanical compatibility is confirmed, enabling direct substitution without circuit modification.

Q: What are the key differences between the MURD620CTH and VS-MURD620CT-M3?

A: The primary differences are: (1) Current rating: VS-MURD620CT-M3 is rated for 6 A per diode versus 3 A for the MURD620CTH; (2) Reverse recovery time: VS-MURD620CT-M3 has 19 ns versus 35 ns for the MURD620CTH; (3) Forward voltage: VS-MURD620CT-M3 specifies 1.2 V @ 6 A versus 1 V @ 3 A for the MURD620CTH; (4) Product status: VS-MURD620CT-M3 is Active while MURD620CTH is Obsolete.

Q: Are there any thermal or reliability concerns when substituting the VS-MURD620CT-M3 for the MURD620CTH?

A: Both parts operate across the identical junction temperature range (-65°C ~ 175°C) and share the same package thermal characteristics (TO-252-3 DPAK). The substitute part's improved reverse recovery time (19 ns) and higher current rating (6 A) do not introduce thermal or reliability concerns in applications designed for the original 3 A specification.

Q: Does the higher current rating of the VS-MURD620CT-M3 affect circuit operation?

A: No. The substitute part's 6 A current rating exceeds the original 3 A specification, providing design margin without affecting circuit operation. The part will operate within its rated parameters in applications designed for 3 A operation.

Q: What is the significance of the improved reverse recovery time in the VS-MURD620CT-M3?

A: The VS-MURD620CT-M3 reverse recovery time of 19 ns is faster than the MURD620CTH specification of 35 ns. This improvement reduces switching losses and electromagnetic interference in high-frequency rectification applications, providing enhanced performance characteristics.

Q: Are both parts RoHS compliant?

A: Yes. Both the MURD620CTH and VS-MURD620CT-M3 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and hazardous substance regulations.

Q: What packaging options are available for the VS-MURD620CT-M3?

A: The VS-MURD620CT-M3 is supplied in Tube packaging. The original MURD620CTH packaging specification is not detailed in the provided data.

Q: Is the VS-MURD620CT-M3 available in production quantities?

A: Yes. The VS-MURD620CT-M3 maintains Active product status with documented inventory availability, ensuring supply chain reliability for production applications.
