SARS02V Equivalent & Substitute Parts

Part Overview

The SARS02V 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 component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The diode operates across a junction temperature range of -40°C to 150°C and complies with RoHS standards.

Substitute Part Grouping Explanation

Substitute parts for the SARS02V are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents maintain identical electrical specifications across all critical parameters: 800 V reverse voltage, 1.2 A average rectified current, 920 mV forward voltage at rated current, standard recovery speed characteristics, and axial through-hole mounting. These parts differ only in packaging format (Tape & Reel versus Cut Tape) or product status (Active versus Obsolete). Parametric equivalents include EM 2BV, EM 2BV1, RO 2BV, SARS01V0, and SARS01V1, all manufactured by Sanken Electric USA Inc.

Similar Parts share the same 800 V reverse voltage rating and axial through-hole mounting but operate at higher current ratings (1.5 A instead of 1.2 A) and exhibit different forward voltage and reverse recovery characteristics. These parts are manufactured by Vishay General Semiconductor and Micro Commercial Co and are suitable for applications where the higher current capability and different electrical characteristics are acceptable within circuit design margins. Similar parts include 1N5398-E3/54, 1N5398-E3/73, 1N5398GP-AP, 1N5398GP-BP, and 1N5398GP-E3/54.

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

Select SARS01V1 or SARS01V0 as primary alternatives. Both parts are manufactured by Sanken Electric USA Inc., maintain identical electrical specifications (800 V, 1.2 A, 920 mV forward voltage, 18 µs reverse recovery time), and are classified as Active products. SARS01V1 is available in Cut Tape packaging, while SARS01V0 is available without specified packaging format. Both comply with RoHS standards and carry MSL 1 (Unlimited) moisture sensitivity rating.

EM 2BV and EM 2BV1 are alternative parametric equivalents from Sanken Electric USA Inc., both rated for 800 V and 1.2 A. EM 2BV is supplied in Tape & Reel format, while EM 2BV1 is supplied in Cut Tape format. Both are Active products with RoHS compliance. Forward voltage is specified at 1.2 A rather than 1.5 A, representing a minor specification variation.

RO 2BV is a Sanken Electric USA Inc. parametric equivalent supplied in Tape & Reel format with Active product status and RoHS compliance. Forward voltage specification matches the original SARS02V at 920 mV @ 1.5 A.

For Higher Current Applications (Similar Parts):

The 1N5398 series from Vishay General Semiconductor and Micro Commercial Co provides 800 V reverse voltage rating with increased current capacity (1.5 A versus 1.2 A). These parts exhibit lower forward voltage (1.4 V @ 1.5 A) and significantly faster reverse recovery time (2 µs versus 18 µs). Selection among 1N5398-E3/54, 1N5398-E3/73, 1N5398GP-AP, 1N5398GP-BP, and 1N5398GP-E3/54 depends on packaging format requirements and procurement specifications. All are Active products with ROHS3 compliance and REACH Unaffected status.

Frequently Asked Questions (FAQ)

Q: Can SARS01V1 directly replace SARS02V in existing designs?

A: Yes. SARS01V1 is a parametric equivalent with identical voltage rating (800 V), current rating (1.2 A), forward voltage (920 mV @ 1.2 A), reverse recovery time (18 µs), and reverse leakage current (10 µA @ 800 V). Both are axial through-hole components. SARS01V1 is Active status, addressing the obsolescence of SARS02V. Packaging format differs (Cut Tape versus Tape & Reel), which affects procurement and assembly processes but not electrical performance.

Q: What is the difference between parametric equivalents and similar parts?

A: Parametric equivalents maintain all critical electrical specifications of the original part, including voltage, current, forward voltage, and recovery characteristics. Similar parts share the same voltage rating and mounting type but operate at different current levels and exhibit different electrical characteristics. The 1N5398 series, for example, operates at 1.5 A instead of 1.2 A and has faster reverse recovery (2 µs versus 18 µs). Similar parts are suitable only when circuit design margins accommodate these differences.

Q: Why does EM 2BV specify forward voltage at 1.2 A while SARS02V specifies it at 1.5 A?

A: Forward voltage is a current-dependent parameter. Specification at different current levels reflects manufacturer test conditions and does not indicate incompatibility. Both parts maintain the same 920 mV forward voltage value, indicating equivalent diode characteristics. The difference in test current reflects standard practice variations among manufacturers.

Q: Are all substitute parts RoHS compliant?

A: Yes. SARS02V and all listed parametric equivalents (EM 2BV, EM 2BV1, RO 2BV, SARS01V0, SARS01V1) are RoHS Compliant. The 1N5398 series parts are ROHS3 Compliant. All parts carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What packaging formats are available for parametric equivalents?

A: Parametric equivalents are available in Tape & Reel (EM 2BV, RO 2BV) and Cut Tape (EM 2BV1, SARS01V1) formats. SARS01V0 packaging format is not specified in available data. Selection depends on assembly equipment compatibility and procurement requirements. Tape & Reel format is standard for automated assembly, while Cut Tape is suitable for manual or semi-automated processes.

Q: Can 1N5398 series parts be used in applications designed for SARS02V?

A: 1N5398 series parts share the 800 V reverse voltage rating and axial through-hole mounting but operate at 1.5 A instead of 1.2 A. Forward voltage is higher (1.4 V versus 920 mV), and reverse recovery time is significantly faster (2 µs versus 18 µs). These differences are acceptable in applications where the circuit design accommodates higher current capacity and faster switching characteristics. Circuit analysis is required to confirm compatibility.

Q: What is the operating temperature range for substitute parts?

A: Parametric equivalents (SARS01V0, SARS01V1, EM 2BV, EM 2BV1, RO 2BV) operate across -40°C to 150°C junction temperature, matching SARS02V. The 1N5398 series from Vishay operates across -65°C to 175°C (1N5398GP-E3/54) or -50°C to 150°C (1N5398-E3/54, 1N5398-E3/73), providing extended temperature capability. Micro Commercial Co 1N5398 variants operate across -55°C to 150°C. Extended temperature ranges do not affect compatibility in applications operating within the original -40°C to 150°C specification.

Q: Are there inventory considerations when selecting substitutes?

A: Current inventory levels are provided for reference: SARS02V (1116 pcs), EM 2BV (1141 pcs), EM 2BV1 (2024 pcs), RO 2BV (838 pcs), SARS01V0 (760 pcs), SARS01V1 (806 pcs), and 1N5398 series variants (728–5600 pcs depending on part number and packaging). Inventory availability should be confirmed with suppliers for production requirements.
