Engineering Selection Recommendations

Both the ES3FHE3_A/H and ES3F-E3/57T are Active product status components manufactured by Vishay General Semiconductor - Diodes Division. Selection between these parts is based on availability and supply chain requirements rather than electrical or mechanical differentiation.

ES3FHE3_A/H is suitable for applications where the specific part number is mandated by design documentation or procurement specifications. Current inventory status: 808 Pcs New Original In Stock.

ES3F-E3/57T is suitable as a direct substitute when ES3FHE3_A/H availability is constrained. This part maintains identical electrical performance, package specifications, and compliance certifications. Current inventory status: 15750 Pcs New Original In Stock.

Both parts satisfy AEC-Q101 automotive qualification requirements and ROHS3 compliance. The choice between these equivalent parts does not impact circuit performance, thermal characteristics, or reliability in applications designed for the ES3FHE3_A/H specification.

Frequently Asked Questions (FAQ)

Q: Can ES3F-E3/57T be used as a direct replacement for ES3FHE3_A/H in automotive applications?

A: Yes. Both parts are AEC-Q101 qualified and maintain identical electrical parameters, forward voltage characteristics, reverse recovery time, and operating temperature ranges. The DO-214AB (SMC) package and surface mount configuration are identical. No circuit redesign or validation is required.

Q: Are there differences in reverse voltage or current ratings between these parts?

A: No. Both parts are rated for 300 V DC reverse voltage and 3 A average rectified current. Forward voltage drop at 3 A is 1.1 V maximum for both parts.

Q: Do these parts have different thermal or reliability characteristics?

A: No. Both parts operate across the same junction temperature range (-55°C to 150°C) and maintain identical reverse leakage current specifications (10 µA @ 300 V) and capacitance characteristics (30 pF @ 4V, 1MHz).

Q: What is the significance of the packaging designation (Tape & Reel)?

A: Tape & Reel (TR) is a supply format for automated assembly processes. This designation does not affect electrical performance or substitution eligibility. Both parts are supplied in this format and are compatible with standard pick-and-place equipment.

Q: Are both parts RoHS compliant?

A: Yes. Both ES3FHE3_A/H and ES3F-E3/57T are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), indicating no moisture bake-out requirement prior to soldering.

Q: What is the base product number relationship?

A: Both parts share the base product number ES3F, indicating they are variants within the same product family with identical core specifications. The suffixes (_A/H and -E3/57T) represent different manufacturing batches or supply chain designations.
