Engineering Selection Recommendations

Primary Equivalent (Recommended for Direct Replacement):

ES1J-13-F (Diodes Incorporated) is the primary parametric equivalent. This part maintains identical electrical specifications to the obsolete ES1J, including 35 ns reverse recovery time, 1.3 V forward voltage, and 20 pF capacitance. The ES1J-13-F is active in production with 5,339 units in stock and carries ROHS3 compliance with MSL 1 (Unlimited) moisture sensitivity rating.

Active Alternatives with Acceptable Parameter Variation:

ES1J-LTP (Micro Commercial Co) provides an active substitute with extended operating temperature range (-65°C to 175°C) and ROHS3 compliance. Forward voltage increases to 1.7 V at 1 A, and capacitance reduces to 15 pF. This part is suitable for applications requiring wider temperature operation.

RS1J (Taiwan Semiconductor Corporation) and Vishay variants (RS1J-E3/5AT, RS1J-E3/61T, RS1J-HF, RS1J-M3/5AT, RS1J-M3/61T) are parametric equivalents with longer reverse recovery times (150 ns to 250 ns) compared to the ES1J (35 ns). These parts maintain 1.3 V forward voltage and are ROHS3 compliant. Selection among Vishay variants depends on packaging requirements (Tape & Reel versus Cut Tape) and capacitance specifications.

Compliance Considerations:

All recommended substitutes carry ROHS3 compliance. The HY Electronic ES1J variant includes AEC-Q101 automotive qualification and is suitable for automotive applications, though REACH status differs (REACH Affected versus REACH Unaffected for other variants).

Inventory Availability:

ES1J-13-F (5,339 units), ES1J-LTP (55,300 units), and RS1J (95,600 units) offer the highest inventory levels for immediate procurement.

Frequently Asked Questions (FAQ)

Q: Can ES1J-13-F directly replace the obsolete ES1J?

A: Yes. ES1J-13-F is a parametric equivalent with identical voltage rating (600 V), current rating (1 A), forward voltage (1.3 V @ 1 A), reverse recovery time (35 ns), and package (DO-214AC, SMA). Both parts are ROHS3 compliant. The primary difference is product status: ES1J-13-F is active in production.

Q: What is the difference between ES1J-13-F and RS1J variants?

A: ES1J-13-F maintains the original 35 ns reverse recovery time. RS1J variants (from Taiwan Semiconductor Corporation and Vishay) have longer reverse recovery times (150 ns to 250 ns). Forward voltage remains 1.3 V for both. The choice depends on circuit switching speed requirements. Faster recovery (35 ns) reduces switching losses in high-frequency applications.

Q: Are all substitute parts available in the same SMA package?

A: Yes. All listed substitutes use the DO-214AC (SMA) surface mount package. Packaging format varies (Cut Tape, Tape & Reel, Digi-Reel), but the physical component package remains identical, enabling direct PCB placement without modification.

Q: What is the significance of reverse recovery time (trr) variation?

A: Reverse recovery time affects switching speed and switching losses. The ES1J and ES1J-13-F specify 35 ns trr, enabling faster switching transitions. RS1J variants specify 150 ns to 250 ns trr, resulting in slower switching but potentially lower cost. Circuit design determines whether the longer recovery time is acceptable.

Q: Can I use ES1J-LTP in place of ES1J?

A: Yes, with parameter awareness. ES1J-LTP maintains 600 V, 1 A ratings and SMA package. Forward voltage increases to 1.7 V (versus 1.3 V), and operating temperature range extends to -65°C to 175°C. The higher forward voltage increases power dissipation; verify thermal design accommodates this change. Reverse recovery time remains 35 ns.

Q: What does ROHS3 compliance mean for this component?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, hexavalent chromium, and specific brominated flame retardants. All listed substitutes carry ROHS3 compliance, ensuring regulatory alignment for EU and equivalent markets.

Q: Which substitute offers the lowest capacitance?

A: RS1J-E3/5AT and RS1J-E3/61T (Vishay) specify 7 pF capacitance at 4 V, 1 MHz. The original ES1J specifies 20 pF. Lower capacitance reduces parasitic effects in high-frequency circuits. Both Vishay parts are ROHS3 compliant and active in production.

Q: Is the HY Electronic ES1J suitable for automotive applications?

A: Yes. The HY Electronic ES1J variant carries AEC-Q101 automotive qualification and is rated for -55°C to 150°C operation. However, forward voltage is specified at 1.7 V (versus 1.3 V for other variants), and REACH status is listed as REACH Affected. Verify compliance requirements for your specific automotive application.

Q: What packaging options are available for RS1J variants?

A: Vishay RS1J variants are supplied in Tape & Reel (TR) or Cut Tape (CT) formats. RS1J-E3/5AT and RS1J-M3/5AT use Tape & Reel. RS1J-E3/61T and RS1J-M3/61T use Cut Tape. Taiwan Semiconductor Corporation RS1J is supplied in Cut Tape & Digi-Reel format. All maintain identical DO-214AC (SMA) component packaging.

Q: What is MSL 1 (Unlimited) moisture sensitivity?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. The part can be stored indefinitely without desiccant packaging or environmental controls. All listed substitutes carry MSL 1 rating, eliminating moisture-related handling constraints.
