ES1DHE3_A/I Equivalent & Substitute Parts

Part Overview

The ES1DHE3_A/I is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount diode operates at 200 V DC reverse voltage with 1 A average rectified current in a DO-214AC (SMA) package. The part is actively produced and carries automotive-grade qualification (AEC-Q101), making it suitable for automotive and industrial applications requiring fast recovery characteristics.

Substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits selection from qualified alternatives that meet identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the ES1DHE3_A/I is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

Voltage - DC Reverse (Vr) Maximum: 200 V
Current - Average Rectified (Io): 1 A
Package / Case: DO-214AC, SMA
Mounting Type: Surface Mount
Operating Temperature Range: -55°C to 150°C minimum

Performance Parameters (Fast Recovery Classification):

Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
Reverse Recovery Time (trr): ≤ 25 ns (primary specification) or ≤ 24 ns (acceptable variance)

Electrical Characteristics (Allowable Variance):

Voltage - Forward (Vf) Maximum @ If: 920 mV @ 1 A (primary) or up to 1.3 V (acceptable for non-automotive alternatives)
Current - Reverse Leakage @ Vr: 5 µA @ 200 V

Frequently Asked Questions (FAQ)

Q: Can ES1D-E3/61T be used as a direct replacement for ES1DHE3_A/I in automotive applications?

A: ES1D-E3/61T is electrically identical to ES1DHE3_A/I but does not carry automotive-grade qualification or AEC-Q101 certification. For automotive applications requiring these certifications, use ES1DHE3_A/H instead.

Q: What is the difference between ES1DHE3_A/I and ES1DHE3_A/H?

A: Both parts are automotive-grade, AEC-Q101 qualified, and electrically identical. The difference is in packaging format: ES1DHE3_A/I is supplied in Tape & Reel (TR), while ES1DHE3_A/H is also Tape & Reel. Inventory levels differ (20200 pcs vs. 24800 pcs).

Q: Are U1D series parts (U1D-E3/5AT, U1D-E3/61T, U1D-M3/5AT) suitable substitutes?

A: U1D series parts meet all critical electrical specifications (200 V, 1 A, 920 mV forward voltage, fast recovery). Reverse recovery time is 24 ns, which is superior to the 25 ns specification. These parts are suitable for non-automotive applications. Capacitance specifications are either not provided or differ (6.8 pF for U1D-M3/5AT).

Q: Why is FS1DE-TP listed as a substitute if it is obsolete?

A: FS1DE-TP is included in the comparison for historical reference and supply chain continuity assessment. Its obsolete status and performance deviations (150 ns reverse recovery time, 1.3 V forward voltage) make it unsuitable for new designs. Limited inventory (868 pcs) further restricts its use.

Q: What packaging options are available for substitutes?

A: All substitute parts use the same DO-214AC (SMA) surface mount package. Packaging format differs: Tape & Reel (TR), Cut Tape (CT) & Digi-Reel, or SMAE supplier device package. These format differences do not affect electrical compatibility but may impact procurement and handling procedures.

Q: Can ES1D (EVVO Semi) be used in high-speed switching applications?

A: ES1D has a reverse recovery time of 35 ns, which exceeds the 25 ns specification of ES1DHE3_A/I. While it remains classified as fast recovery (≤ 500 ns), applications requiring the faster 25 ns recovery time should use ES1DHE3_A/I, ES1DHE3_A/H, or ES1D-13-F instead.

Q: Is RoHS3 compliance verified for all substitute parts?

A: All listed substitute parts carry RoHS3 Compliant status. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all Vishay parts, indicating no moisture sensitivity restrictions during storage and handling.

Q: What is the inventory status for each substitute?

A: ES1D-E3/61T has the highest availability (2,328,659 pcs). ES1D-13-F (Diodes Incorporated) offers 550,400 pcs. For automotive-qualified alternatives, ES1DHE3_A/H provides 24,800 pcs. FS1DE-TP has the lowest availability (868 pcs) and is obsolete.
