VS-45LR60 Equivalent & Substitute Parts

Part Overview

The VS-45LR60 is a general-purpose reverse polarity diode rated for 600 V DC reverse voltage and 150 A average rectified current in a DO-205AC (DO-30) stud mount package. This component is classified as obsolete, indicating that direct procurement from original manufacturing sources may be limited or unavailable. Identification of equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades.

Speed	Standard Recovery >500ns, > 200mA (Io)
Mounting Type	Stud Mount
Package / Case	DO-205AC, DO-30, Stud
Operating Temperature - Junction	-40°C ~ 200°C
RoHS Status	ROHS3 Compliant

Substitute Part Grouping Explanation

Substitution of the VS-45LR60 is determined by equivalence in the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

Voltage - DC Reverse (Vr) (Max): 600 V minimum
Current - Average Rectified (Io): 150 A minimum
Technology: Standard, Reverse Polarity
Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

Mechanical Equivalence Criteria:

Mounting Type: Stud Mount
Package Category: DO-205 series stud mount packages

The VS-150UR60D meets these substitution criteria with identical voltage and current ratings, equivalent stud mount configuration, and matching regulatory compliance status. Differences in forward voltage characteristics and recovery speed do not preclude substitution within the defined electrical operating envelope.

Engineering Selection Recommendations

The VS-150UR60D is the designated manufacturer substitute for the obsolete VS-45LR60. Both components are manufactured by Vishay General Semiconductor - Diodes Division and maintain identical electrical ratings for reverse voltage (600 V) and average rectified current (150 A).

The VS-150UR60D carries active product status, ensuring ongoing availability and supply chain continuity. Both parts satisfy ROHS3 compliance and REACH regulatory requirements, supporting deployment in regulated applications.

The VS-150UR60D features a DO-205AA (DO-8) package with chassis and stud mount capability, compared to the DO-205AC (DO-30) stud mount configuration of the VS-45LR60. Physical dimensions and mounting interface compatibility must be verified against specific application requirements prior to implementation.

The operating temperature range of the VS-150UR60D extends to -40°C minimum with a maximum junction temperature of 180°C, compared to 200°C for the VS-45LR60. Applications requiring operation above 180°C junction temperature require design review.

Frequently Asked Questions (FAQ)

Q: Can the VS-150UR60D directly replace the VS-45LR60 in all applications?

A: The VS-150UR60D meets the electrical requirements (600 V, 150 A) and regulatory compliance of the VS-45LR60. However, physical package differences between DO-205AC and DO-205AA require verification of mounting interface compatibility and thermal management characteristics for the specific application.

Q: What is the significance of the different recovery speeds?

A: The VS-45LR60 operates with standard recovery (>500ns), while the VS-150UR60D features fast recovery (≤500ns). Fast recovery reduces switching losses in high-frequency applications. For standard rectification applications, both recovery characteristics are functionally equivalent within the defined electrical operating envelope.

Q: Are there temperature limitations when substituting the VS-150UR60D?

A: The VS-150UR60D has a maximum junction temperature of 180°C, compared to 200°C for the VS-45LR60. Applications designed for operation above 180°C junction temperature require thermal design review to ensure the substitute part operates within specified limits.

Q: What packaging differences exist between these parts?

A: The VS-45LR60 uses DO-205AC (DO-30) stud mount packaging. The VS-150UR60D uses DO-205AA (DO-8) stud mount packaging with additional chassis mount capability. Both are stud mount configurations, but physical dimensions and mounting hole specifications differ. Mechanical compatibility must be confirmed for the target application.

Q: Why is the VS-45LR60 classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The VS-150UR60D, with active product status, represents the current manufacturing equivalent and is the recommended substitute for new designs and ongoing production requirements.

Q: Are both parts compliant with environmental regulations?

A: Both the VS-45LR60 and VS-150UR60D are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for component deployment in regulated markets.
