Current - Average Rectified (Io): 1 A
Package / Case: DO-214AC, SMA
Mounting Type: Surface Mount
Operating Temperature Range: -55°C ~ 150°C
Technology: Standard

Secondary Parameters Allowing Variation:

Reverse Recovery Time (trr): 24–25 ns (minor variation acceptable)
Voltage - Forward (Vf) (Max) @ If: 920 mV to 1 V (within acceptable tolerance)
Reverse Leakage Current: 5 µA @ 200 V (consistent across all substitutes)
Capacitance @ Vr, F: 6.8–20 pF (variation within acceptable range for general-purpose applications)

All substitute parts listed maintain the same DO-214AC package footprint, surface mount compatibility, and core electrical ratings. Automotive-grade variants (ES1DHE3_A/H and ES1DHE3_A/I) include AEC-Q101 qualification matching the main part. Non-automotive variants and alternative manufacturers (EVVO Semi ES1D, Diodes Incorporated ES1D-13-F) provide equivalent electrical performance with standard-grade qualification.

Engineering Selection Recommendations

Automotive Applications (AEC-Q101 Required): For applications requiring automotive qualification, select ES1DHE3_A/H or ES1DHE3_A/I. Both parts maintain identical electrical specifications to the ES1DHM3_A/I and carry AEC-Q101 qualification. ES1DHE3_A/H provides 24800 pieces in inventory, while ES1DHE3_A/I provides 20200 pieces. Both are suitable for direct substitution in automotive-grade designs.

Standard Industrial Applications: For non-automotive applications, Vishay ES1D-E3/61T offers the highest inventory availability (2,328,659 pieces) with identical electrical parameters to the main part. ES1D-E3/5AT and ES1D-M3/61T provide alternative packaging options (Cut Tape & Digi-Reel versus Tape & Reel) with equivalent performance.

Alternative Manufacturers: Diodes Incorporated ES1D-13-F provides the largest inventory (550,400 pieces) with matching core electrical specifications. EVVO Semi ES1D offers 140,400 pieces in stock with acceptable parameter variation (Vf max 1 V, trr 35 ns, capacitance 15 pF).

Reverse Recovery Time Consideration: Vishay U1D series parts (U1D-E3/5AT, U1D-E3/61T, U1D-M3/5AT) feature 24 ns reverse recovery time, which is 1 ns faster than the main part. This variation is within acceptable tolerance for general-purpose rectification applications.

Capacitance Variation: Capacitance values range from 6.8 pF to 20 pF across substitute parts. For applications sensitive to junction capacitance, U1D-M3/5AT (6.8 pF) provides the lowest value, while ES1D-13-F (20 pF) provides the highest. The main part and most Vishay substitutes specify 10 pF.

Frequently Asked Questions (FAQ)

Q: Can ES1D-E3/61T be used as a direct replacement for ES1DHM3_A/I?

A: ES1D-E3/61T is electrically equivalent to ES1DHM3_A/I with identical voltage, current, forward voltage, and reverse recovery time specifications. However, ES1D-E3/61T is standard-grade (not automotive-qualified), while ES1DHM3_A/I carries AEC-Q101 qualification. For automotive applications, use ES1DHE3_A/H or ES1DHE3_A/I instead.

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

A: Both parts are automotive-grade (AEC-Q101) with identical electrical specifications. The difference lies in packaging designation and inventory availability. ES1DHE3_A/H has 24800 pieces in stock, while ES1DHE3_A/I has 20200 pieces. Both are suitable for direct substitution in automotive designs.

Q: Are Vishay U1D series parts compatible with ES1DHM3_A/I?

A: U1D series parts (U1D-E3/5AT, U1D-E3/61T, U1D-M3/5AT) are compatible substitutes with matching 200 V, 1 A ratings and DO-214AC packaging. The reverse recovery time is 24 ns (1 ns faster than the main part), which is acceptable for general-purpose rectification. Capacitance specifications vary: U1D-E3 variants do not specify capacitance, while U1D-M3/5AT specifies 6.8 pF.

Q: Can I use Diodes Incorporated ES1D-13-F in place of ES1DHM3_A/I?

A: ES1D-13-F is electrically compatible with matching 200 V, 1 A ratings, 920 mV forward voltage, and 25 ns reverse recovery time. The package is DO-214AC (SMA), ensuring mechanical compatibility. ES1D-13-F is standard-grade (not automotive-qualified). For non-automotive applications, ES1D-13-F is a suitable substitute with the highest inventory availability (550,400 pieces).

Q: What is the impact of capacitance variation among substitute parts?

A: Capacitance values range from 6.8 pF to 20 pF across substitute parts. For most general-purpose rectification applications, this variation has minimal impact on circuit performance. Applications with specific high-frequency or switching requirements should verify capacitance specifications against circuit design parameters. The main part specifies 10 pF, which is mid-range among available substitutes.

Q: Is EVVO Semi ES1D suitable for critical applications?

A: EVVO Semi ES1D meets the core electrical requirements (200 V, 1 A, DO-214AC package) but exhibits parameter variations: forward voltage maximum of 1 V (versus 920 mV for the main part) and reverse recovery time of 35 ns (versus 25 ns). These variations are within acceptable tolerance for general-purpose rectification. For applications with strict performance requirements, Vishay or Diodes Incorporated parts are recommended.

Q: What packaging options are available for substitutes?

A: Substitute parts are available in two packaging formats: Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel®. The main part ES1DHM3_A/I is supplied in Tape & Reel. Vishay ES1D-E3/5AT and ES1D-E3/61T offer Cut Tape & Digi-Reel® options. All parts use the same DO-214AC (SMA) component package, ensuring identical PCB footprint and mounting compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: All listed substitute parts are RoHS3 compliant with Moisture Sensitivity Level (MSL) 1 (Unlimited). This ensures compatibility with standard manufacturing processes and environmental regulations.
