SARS02 Equivalent & Substitute Parts Reference
Part Overview
SARS02, manufactured by Sanken Electric USA Inc., is an obsolete diode in the category of Diodes, Rectifiers, having essential characteristics like 800 V reverse voltage, 1.2A average rectified current, axial through-hole mounting, and standard recovery speed. As the SARS02 diode is classified as obsolete, sourcing directly is restricted, necessitating a search for suitable alternative models that maintain the original electrical and mechanical parameters for direct interchange in designs.

Engineering Selection Recommendations
The SARS02 diode is obsolete and is not in active production. EM2B and SARS01, both manufactured by Sanken Electric USA Inc., are parametric equivalents, active, and available in inventory. All listed substitute parts retain RoHS compliance and MSL 1 (Unlimited), suitable for unrestricted handling and assembly. Selection should be based on product status and compliance fields; EM2B and SARS01 are both direct substitutes for SARS02 within the same through-hole axial package and electrical parameters.
Frequently Asked Questions (FAQ)
Q1: What makes EM2B and SARS01 valid substitutes for SARS02?
Both EM2B and SARS01 have identical voltage rating, current rating, package/case type, operating temperature, RoHS Status, and mounting method as SARS02.
Q2: Are there differences in form factor or mounting between SARS02 and the substitutes?
All parts feature through-hole axial packages, ensuring fitment and compatibility in existing designs.
Q3: Is there any difference in reverse recovery time?
SARS02 and SARS01 both state 18 µs, while EM2B does not specify reverse recovery time in the provided parameters.
Q4: Can these substitutes be used in RoHS-compliant applications?
All listed parts are RoHS Compliant.
Q5: What product status should be considered during selection?
SARS02 is obsolete; EM2B and SARS01 are active products and available in inventory.
Q6: What moisture sensitivity considerations apply?
All parts are rated MSL 1 (Unlimited), supporting standard storage and assembly processes without additional precautions.
