Engineering Selection Recommendations

ES1JL (Taiwan Semiconductor Corporation)

The ES1JL is a parametric equivalent to the ES1JL RHG with identical electrical specifications. However, this part is designated as "Not For New Designs," indicating it is in mature or obsolescence phase. Selection of this part is appropriate only for replacement or maintenance applications where the original part number must be maintained. For new design implementations, alternative active-status parts are preferred.

HS1JL RVG (Taiwan Semiconductor Corporation)

The HS1JL RVG maintains Active product status and matches all primary substitution criteria: 600 V reverse voltage, 1 A average rectified current, and DO-219AB package. The reverse recovery time is 75 ns compared to 35 ns for the ES1JL RHG, and capacitance is 15 pF versus 8 pF. These differences remain within fast recovery classification (≤ 500 ns). This part is suitable for direct substitution in applications where the extended reverse recovery time does not impact circuit performance.

VS-1EFU06HM3/I (Vishay General Semiconductor - Diodes Division)

The VS-1EFU06HM3/I is a similar part with matching 600 V and 1 A ratings in DO-219AB package. This part carries Automotive grade qualification (AEC-Q101) and extended operating temperature range (-55 to 175°C). Forward voltage is 1.2 V at 1 A, lower than the ES1JL RHG specification of 1.7 V, and reverse leakage is 3 µA versus 5 µA. Reverse recovery time is 32 ns. This part is suitable for substitution in applications requiring automotive-grade reliability or extended temperature operation.

VS-2EFU06HM3/I (Vishay General Semiconductor - Diodes Division)

The VS-2EFU06HM3/I is rated for 2 A average rectified current, exceeding the 1 A requirement of the ES1JL RHG. All other parameters—600 V reverse voltage, DO-219AB package, Automotive grade, AEC-Q101 qualification—align with substitution criteria. This part is suitable for applications where higher current capacity provides design margin or where a single part number can serve multiple current requirements. Forward voltage is 1.35 V at 2 A.

Frequently Asked Questions (FAQ)

Q: Can the ES1JL be used as a direct replacement for the ES1JL RHG?

A: The ES1JL is electrically identical to the ES1JL RHG with matching voltage, current, and package specifications. However, the ES1JL is designated "Not For New Designs." It is suitable for replacement applications but not recommended for new circuit designs. For new designs, select HS1JL RVG or Vishay alternatives with Active status.

Q: What is the difference between the HS1JL RVG and the ES1JL RHG?

A: Both parts share 600 V reverse voltage, 1 A current rating, and DO-219AB package. The HS1JL RVG has a reverse recovery time of 75 ns compared to 35 ns for the ES1JL RHG, and higher capacitance (15 pF versus 8 pF). Both remain within fast recovery classification. The HS1JL RVG is Active status, making it suitable for new designs.

Q: Why would I select the VS-2EFU06HM3/I over the VS-1EFU06HM3/I?

A: The VS-2EFU06HM3/I is rated for 2 A average rectified current, providing higher current capacity than the 1 A requirement of the ES1JL RHG. Selection depends on circuit requirements. If the application requires only 1 A, the VS-1EFU06HM3/I is appropriate. If higher current capacity is needed or if a single part number must serve multiple applications, the VS-2EFU06HM3/I is suitable.

Q: Are the Vishay parts (VS-1EFU06HM3/I and VS-2EFU06HM3/I) compatible with the ES1JL RHG package?

A: Yes. Both Vishay parts use the DO-219AB package, which is identical to the Sub SMA package of the ES1JL RHG. Surface mount footprints are compatible. Both parts are RoHS3 compliant with MSL 1 rating.

Q: What does "Not For New Designs" mean for the ES1JL?

A: "Not For New Designs" indicates the part is in mature phase and may face future discontinuation. While the part remains available and functional, manufacturers recommend using alternative active-status parts for new circuit designs to ensure long-term supply continuity and support.

Q: Do the Vishay parts have better performance than the Taiwan Semiconductor parts?

A: The Vishay parts (VS-1EFU06HM3/I and VS-2EFU06HM3/I) feature lower forward voltage (1.2 V and 1.35 V respectively versus 1.7 V), lower reverse leakage (3 µA versus 5 µA), Automotive grade qualification, AEC-Q101 certification, and extended operating temperature range (-55 to 175°C versus -55 to 150°C). These characteristics make Vishay parts suitable for automotive and high-reliability applications. Selection depends on specific application requirements.

Q: Can I use these parts interchangeably in my circuit?

A: Interchangeability depends on circuit requirements. All listed parts share 600 V reverse voltage and DO-219AB package. Current rating differences (1 A versus 2 A) and forward voltage variations must be evaluated against circuit design specifications. Reverse recovery time differences may affect switching performance in high-frequency applications. Verify that the selected part meets all electrical and thermal requirements of your specific application.

Q: What is the significance of AEC-Q101 qualification?

A: AEC-Q101 is an automotive industry qualification standard for discrete semiconductors. Parts carrying this qualification (VS-1EFU06HM3/I and VS-2EFU06HM3/I) have undergone rigorous testing for reliability, temperature cycling, and performance consistency. This qualification is required for automotive applications and indicates suitability for demanding environments.
