Frequently Asked Questions (FAQ)

Q: Can TSSW3U45 be used as a direct replacement for TSSW3U45HRVG?

A: Yes. Both parts are parametric equivalents with identical electrical ratings (45 V, 3 A, 470 mV forward voltage), identical package specifications (SOD-123W surface mount), and identical operating temperature range (-55°C ~ 150°C). No circuit modifications are required.

Q: Are there differences in forward voltage characteristics between these parts?

A: No. Both TSSW3U45HRVG and TSSW3U45 specify 470 mV maximum forward voltage at 3 A. Reverse leakage current is identical at 1 mA @ 45 V.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. ECCN and HTSUS classifications are identical.

Q: What is the difference between TSSW3U45HRVG and TSSW3U45 part numbers?

A: The part numbers differ in suffix designation. The electrical and mechanical specifications are identical. The suffix variation does not indicate functional differences in this product line.

Q: Are these parts suitable for high-frequency switching applications?

A: Both parts feature fast recovery characteristics (≤ 500ns, > 200mA Io), which supports switching applications within the specified current and voltage ratings.

Q: Can these Schottky diodes be used in parallel for higher current applications?

A: Circuit design considerations for parallel operation are outside the scope of parametric equivalence. Consult application-specific design guidelines for current sharing and thermal management in parallel configurations.

Q: What packaging format is supplied for these parts?

A: Both TSSW3U45HRVG and TSSW3U45 are supplied in Tape & Reel (TR) format, suitable for automated pick-and-place assembly on standard SMT equipment.
