Engineering Selection Recommendations

Both the ES1ALHRFG and HS1AL RVG are Active product status components manufactured by Taiwan Semiconductor Corporation with identical automotive-grade qualification under AEC-Q101 standard. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for automotive and industrial applications.

The ES1ALHRFG and HS1AL RVG are electrically and mechanically interchangeable for all applications requiring a 50 V, 1 A general-purpose rectifier diode in DO-219AB Sub SMA surface mount package. The minor variation in reverse recovery time (35 ns versus 50 ns) and junction capacitance (10 pF versus 20 pF) does not affect functional equivalence within the Fast Recovery classification and standard application parameters.

Selection between these parts may be based on inventory availability, packaging format preference (ES1ALHRFG supplied in standard packaging versus HS1AL RVG in Cut Tape format), or supply chain considerations, with no technical performance differentiation for standard rectification applications.

Frequently Asked Questions (FAQ)

Q: Are ES1ALHRFG and HS1AL RVG pin-compatible?

A: Yes. Both components use the DO-219AB package with identical Sub SMA supplier device package designation and surface mount mounting type, ensuring direct mechanical and electrical compatibility on printed circuit boards.

Q: What is the significance of the reverse recovery time difference between the two parts?

A: The ES1ALHRFG specifies 35 ns reverse recovery time while the HS1AL RVG specifies 50 ns. Both values fall within the Fast Recovery classification (≤ 500 ns for currents > 200 mA). This variation does not affect functional performance in standard rectification applications and does not impact circuit operation within the specified electrical parameters.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the ES1ALHRFG and HS1AL RVG carry Automotive grade classification and AEC-Q101 qualification, meeting automotive industry standards for reliability and quality assurance.

Q: What is the difference in packaging between these two parts?

A: The ES1ALHRFG is supplied in standard packaging format, while the HS1AL RVG is supplied in Cut Tape (CT) format. Both use the DO-219AB package case. Selection between packaging formats depends on assembly process requirements and inventory management practices.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical Moisture Sensitivity Level (MSL) rating of 1 (Unlimited). Regulatory and environmental compliance is equivalent for both components.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The ES1ALHRFG and HS1AL RVG are functionally equivalent for all applications requiring a 50 V, 1 A general-purpose rectifier diode. No circuit redesign or validation is required for substitution between these parts.

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

A: Both the ES1ALHRFG and HS1AL RVG operate across a junction temperature range of -55°C to 150°C, providing identical thermal performance specifications for automotive and industrial applications.
