Substitute Part Grouping Explanation

Substitute parts for the ES2D/1 are grouped into three categories based on substitution criteria:

Parametric Equivalents (Vishay ES2D Series): Parts ES2D-E3/52T, ES2D-E3/5BT, ES2D-M3/52T, ES2DHE3_A/H, ES2DHE3_A/I, and U2D-E3/52T maintain identical electrical specifications (200 V, 2 A, fast recovery characteristics) and package format (DO-214AA SMB). These parts differ in packaging configuration (Cut Tape, Tape & Reel), RoHS compliance status, and reverse recovery time variations (20–30 ns). The ES2DHE3 variants include automotive-grade qualification (AEC-Q101) and reduced reverse recovery time (20 ns).

Manufacturer Recommended Alternatives: ES2D from Good-Ark Semiconductor and ES2D-13-F from Diodes Incorporated provide equivalent electrical performance within specified tolerances. Forward voltage and reverse recovery time show minor variations within acceptable ranges for general-purpose rectification applications.

Current-Limited Alternative: MURS120T3G from onsemi operates at reduced current rating (1 A versus 2 A) while maintaining 200 V reverse voltage rating and fast recovery characteristics. This part is suitable only for applications where 1 A current capacity is sufficient.

Substitution is determined by: (1) matching or exceeding voltage and current ratings, (2) maintaining fast recovery speed classification, (3) compatible DO-214AA SMB package format, and (4) surface mount mounting type.

Engineering Selection Recommendations

Primary Substitutes (Full Electrical and Mechanical Equivalence):

ES2D-E3/52T, ES2D-E3/5BT, ES2D-M3/52T, ES2DHE3_A/H, ES2DHE3_A/I, and U2D-E3/52T from Vishay are direct substitutes with identical 200 V / 2 A ratings and DO-214AA SMB package format. All are ROHS3 compliant, addressing regulatory requirements where the original ES2D/1 is non-compliant. ES2DHE3 variants include AEC-Q101 automotive qualification and reduced reverse recovery time (20 ns), suitable for automotive and high-reliability applications. Inventory availability ranges from 6,400 to 155,985 units across variants.

Secondary Substitutes (Manufacturer Alternatives):

ES2D from Good-Ark Semiconductor and ES2D-13-F from Diodes Incorporated maintain 200 V / 2 A specifications with minor forward voltage variations (950 mV and 920 mV respectively, compared to 900 mV nominal). Both are ROHS3 compliant with high inventory availability (89,400 and 130,906 units). These parts are suitable where manufacturer flexibility is acceptable and forward voltage tolerance is within circuit design margins.

Current-Limited Alternative:

MURS120T3G from onsemi is restricted to 1 A average rectified current and is suitable only for applications where the 2 A rating of the ES2D/1 is not required. This part maintains 200 V reverse voltage rating and fast recovery characteristics but cannot substitute in circuits requiring full 2 A capacity.

Compliance Consideration:

The original ES2D/1 is RoHS non-compliant. All substitute parts listed are ROHS3 compliant, making them mandatory selections for applications subject to RoHS regulations.

Frequently Asked Questions (FAQ)

Q: Can ES2D-E3/52T directly replace ES2D/1 in existing designs?

A: Yes. ES2D-E3/52T maintains identical electrical specifications (200 V, 2 A, 30 ns reverse recovery time) and DO-214AA SMB package format. The primary difference is packaging configuration (Cut Tape versus unspecified for ES2D/1) and ROHS3 compliance status. No circuit modifications are required.

Q: What is the difference between ES2D-E3/5BT and ES2D-E3/52T?

A: Both parts have identical electrical specifications and ROHS3 compliance. The difference is packaging format: ES2D-E3/5BT is supplied in Tape & Reel (TR) configuration, while ES2D-E3/52T is supplied in Cut Tape (CT). Selection depends on assembly process requirements and order quantity.

Q: Are the automotive-qualified ES2DHE3_A/H and ES2DHE3_A/I variants suitable for non-automotive applications?

A: Yes. Automotive-qualified parts (AEC-Q101) exceed standard reliability requirements and are suitable for any application. The reduced reverse recovery time (20 ns versus 30 ns) provides improved switching performance. These parts are direct substitutes for general-purpose applications.

Q: Why is MURS120T3G listed as a substitute if it has only 1 A current rating?

A: MURS120T3G is listed as a current-limited alternative for applications where 1 A capacity is sufficient. It maintains 200 V reverse voltage and fast recovery characteristics but cannot substitute in circuits requiring the full 2 A rating of the ES2D/1.

Q: What is the significance of the 20 ns versus 30 ns reverse recovery time difference?

A: Reverse recovery time (trr) affects switching speed and switching losses. Shorter trr (20 ns in ES2DHE3 variants) results in faster diode turn-off and reduced reverse recovery current, beneficial in high-frequency switching applications. The 30 ns specification of ES2D/1 is standard for general-purpose rectification.

Q: Are there inventory constraints affecting part selection?

A: Inventory availability varies significantly across substitutes. ES2D-E3/52T has the highest inventory (155,985 units), while ES2D-M3/52T has the lowest (6,400 units). For high-volume production, ES2D-E3/52T, U2D-E3/52T, or ES2D-13-F are recommended based on availability.

Q: Does forward voltage variation between substitutes affect circuit performance?

A: Forward voltage ranges from 875 mV (MURS120T3G) to 950 mV (Good-Ark ES2D) compared to 900 mV nominal for ES2D/1. This variation affects power dissipation and voltage drop across the diode. Circuit designs with tight voltage regulation requirements should account for this tolerance band.

Q: What is the impact of switching from RoHS non-compliant ES2D/1 to ROHS3 compliant substitutes?

A: ROHS3 compliance ensures the part meets Restriction of Hazardous Substances Directive requirements, eliminating lead and other restricted substances. This is mandatory for products sold in regulated markets. Electrical and mechanical performance remains unchanged.
