SARS02V1 Equivalent & Substitute Parts

Part Overview

The SARS02V1 is a general-purpose rectifier diode manufactured by Sanken Electric USA Inc., rated for 800 V DC reverse voltage and 1.2 A average rectified current in an axial through-hole package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The SARS02V1 operates across a junction temperature range of -40°C to 150°C with standard recovery characteristics and is suitable for general rectification applications requiring high voltage tolerance.

Substitute Part Grouping Explanation

Substitution of the SARS02V1 is determined by strict equivalence across the following critical parameters: voltage rating (800 V DC reverse), current rating (1.2 A average rectified), forward voltage characteristics, reverse recovery behavior, reverse leakage current, and through-hole axial mounting configuration. Parts are grouped into two categories based on these criteria:

Parametric Equivalents maintain identical or compatible electrical specifications and mounting type, differing only in packaging format (Cut Tape versus Tape & Box) or minor variations in forward voltage test conditions. These parts are direct functional replacements.

Similar Parts share the same voltage and mounting characteristics but feature higher current ratings (1.5 A) and different package styles (DO-204AL, DO-15). These parts are suitable for applications where the higher current capacity does not create design conflicts and where package compatibility is acceptable.

Engineering Selection Recommendations

Primary Substitutes (Parametric Equivalents):

SARS01V1 and SARS01V0 are the preferred direct replacements for the obsolete SARS02V1. Both parts are manufactured by Sanken Electric USA Inc., maintain identical voltage and current ratings, and are classified as active products with RoHS compliance. SARS01V1 is available in Cut Tape packaging with 806 pieces in stock, while SARS01V0 is available with 760 pieces in stock. Both feature the same 18 µs reverse recovery time and axial through-hole configuration as the original part.

EM 2BV1 and EM 2BV0 are alternative parametric equivalents from Sanken Electric USA Inc., both rated for 800 V and 1.2 A with active product status and RoHS compliance. EM 2BV1 is available in Cut Tape with 2024 pieces in stock, offering superior availability. EM 2BV0 is available in Tape & Box packaging with 1035 pieces in stock.

RO 2BV1 is an active parametric equivalent from Sanken Electric USA Inc. with identical voltage and current specifications, RoHS compliance, and 1032 pieces in stock.

Secondary Substitutes (Similar Parts with Higher Current Rating):

The 1N5398 series parts (1N5398-E3/54, 1N5398-E3/73, 1N5398GP-AP, 1N5398GP-BP, 1N5398GP-E3/54) maintain the 800 V voltage rating but feature 1.5 A current capacity. These parts are suitable for applications where the increased current margin does not create design conflicts. All are active products with RoHS compliance. Package styles differ (DO-204AL, DO-15) from the original axial configuration, requiring verification of board layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can SARS01V1 be used as a direct replacement for SARS02V1?

A: Yes. SARS01V1 is a parametric equivalent with identical voltage (800 V), current (1.2 A), forward voltage (920 mV @ 1.2 A), reverse recovery time (18 µs), and reverse leakage current (10 µA @ 800 V) specifications. Both are through-hole axial packages. SARS01V1 is active and RoHS compliant, making it suitable for direct substitution.

Q: What is the difference between EM 2BV0 and EM 2BV1?

A: Both parts are parametric equivalents with identical electrical specifications (800 V, 1.2 A, 920 mV @ 1.2 A, 10 µA @ 800 V). The primary difference is packaging: EM 2BV0 is supplied in Tape & Box format with 1035 pieces in stock, while EM 2BV1 is supplied in Cut Tape format with 2024 pieces in stock. Selection depends on procurement and assembly requirements.

Q: Can 1N5398 series parts replace SARS02V1?

A: 1N5398 series parts share the 800 V voltage rating and through-hole mounting but feature 1.5 A current capacity compared to the 1.2 A rating of SARS02V1. These parts are suitable for applications where higher current capacity is acceptable and does not create design conflicts. Package styles vary (DO-204AL, DO-15) from the original axial configuration, requiring board layout verification.

Q: What is the significance of the reverse recovery time (trr) parameter?

A: Reverse recovery time affects switching speed and switching losses in rectifier applications. SARS02V1 specifies 18 µs trr. Parametric equivalents SARS01V1 and SARS01V0 maintain this specification. The 1N5398 series parts feature 2 µs trr, indicating faster switching characteristics. Selection depends on application switching frequency requirements.

Q: Are all substitute parts RoHS compliant?

A: All parametric equivalents (SARS01V1, SARS01V0, EM 2BV1, EM 2BV0, RO 2BV1) are RoHS compliant. Among the 1N5398 series, 1N5398-E3/54, 1N5398-E3/73, 1N5398GP-AP, and 1N5398GP-E3/54 are ROHS3 compliant. 1N5398GP-BP does not specify RoHS status in the provided data.

Q: What packaging options are available for parametric equivalents?

A: Parametric equivalents are available in Cut Tape (SARS01V1, EM 2BV1) and Tape & Box (EM 2BV0) formats. All maintain the through-hole axial package configuration. Selection depends on assembly equipment compatibility and procurement volume requirements.

Q: How does forward voltage affect circuit performance?

A: Forward voltage drop affects power dissipation and voltage regulation in rectifier circuits. SARS02V1 specifies 920 mV @ 1.5 A. Parametric equivalents specify 920 mV @ 1.2 A, maintaining equivalent performance. The 1N5398 series specifies 1.4 V @ 1.5 A, resulting in higher forward voltage drop and increased power dissipation.
