Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ES1A-E3/5AT are grouped into two categories based on electrical and mechanical compatibility:

Direct Substitutes (Equivalent Performance): Parts that match or exceed the primary electrical specifications of 50 V reverse voltage, 1 A average rectified current, and DO-214AC (SMA) package form factor. These substitutes maintain fast recovery characteristics (≤500 ns) and operate within compatible temperature ranges.

Upgrade Substitutes (Enhanced Voltage Rating): Parts that exceed the 50 V reverse voltage specification while maintaining 1 A current rating and identical package form factor. These provide higher voltage margin for applications requiring additional design headroom.

Key Parameters for Substitution Compatibility:

• Voltage - DC Reverse (Vr) (Max): Must equal or exceed 50 V
• Current - Average Rectified (Io): Must equal or exceed 1 A
• Package / Case: Must be DO-214AC (SMA)
• Mounting Type: Must be Surface Mount
• Speed Classification: Fast Recovery (≤500 ns) preferred for direct substitution

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution (Equivalent Electrical Performance):

ES1A-13-F (Diodes Incorporated) is the primary equivalent substitute. This part maintains identical voltage and current ratings (50 V, 1 A), matching forward voltage (920 mV @ 1 A), and reverse recovery time (25 ns). Both devices are Active product status and RoHS3 compliant. The operating temperature range of ES1A-13-F extends to 150°C maximum, which is 5°C lower than the main part but remains suitable for most applications within the specified -55°C to 150°C junction temperature window.

For Enhanced Voltage Margin:

STTH102A (STMicroelectronics) provides a 200 V reverse voltage rating while maintaining 1 A current capacity in the same DO-214AC package. This upgrade substitute is suitable for applications requiring higher voltage headroom. The device exhibits faster reverse recovery time (20 ns) and lower reverse leakage current (1 µA @ 200 V). Maximum junction temperature is 175°C, exceeding the main part specification.

For Lower Forward Voltage Drop:

STPS160A (STMicroelectronics) is a Schottky diode with 60 V reverse voltage rating and significantly reduced forward voltage drop (670 mV @ 1 A compared to 920 mV). This substitute is applicable in power-sensitive designs where minimizing forward voltage loss is critical. The Schottky technology provides inherently lower forward voltage characteristics. Product status is Active with RoHS3 compliance.

For Legacy Design Compatibility:

GF1A (onsemi) matches the 50 V, 1 A specifications but carries "Not For New Designs" product status. This part is retained in the substitute list for existing designs requiring component replacement but should not be selected for new development.

ES1A (YAGEO) and S1A (YAGEO) are listed as manufacturer-recommended alternatives with 50 V ratings and Active product status. Limited detailed specifications are provided for these parts; verification of complete electrical characteristics is necessary before selection.

Frequently Asked Questions (FAQ)

Q: Can ES1A-13-F be used as a direct replacement for ES1A-E3/5AT?

A: Yes. ES1A-13-F is a direct substitute with identical voltage (50 V), current (1 A), forward voltage (920 mV @ 1 A), and reverse recovery time (25 ns) specifications. Both are surface mount DO-214AC packages with Active product status and RoHS3 compliance. The maximum junction temperature of ES1A-13-F is 150°C, which is 5°C lower than the main part but remains within acceptable operating ranges for most applications.

Q: What is the difference between STTH102A and the main part ES1A-E3/5AT?

A: STTH102A is an upgrade substitute with a higher reverse voltage rating of 200 V compared to 50 V in the main part. Both maintain 1 A current capacity and use the same DO-214AC package. STTH102A exhibits faster reverse recovery (20 ns versus 25 ns) and lower reverse leakage current (1 µA @ 200 V versus 5 µA @ 50 V). The higher voltage rating makes STTH102A suitable for applications requiring additional voltage margin.

Q: Why is STPS160A listed as a substitute if it uses Schottky technology?

A: STPS160A is a Schottky diode substitute that maintains the 1 A current rating and DO-214AC package compatibility. The primary advantage is significantly lower forward voltage drop (670 mV @ 1 A versus 920 mV), which reduces power dissipation in current-limited applications. The 60 V reverse voltage rating exceeds the 50 V requirement. Schottky technology is fundamentally different from standard rectifier diodes; selection depends on application requirements for forward voltage characteristics.

Q: Should GF1A be used for new designs?

A: No. GF1A carries "Not For New Designs" product status. This part is listed for reference in existing designs requiring component replacement but should not be selected for new development. ES1A-13-F or STTH102A are preferred alternatives for new designs.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (ES1A-13-F, STTH102A, STPS160A, GF1A, ES1A, and S1A) are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the main part ES1A-E3/5AT compliance status.

Q: What is the difference between fast recovery and standard recovery speed classifications?

A: Fast recovery diodes have reverse recovery time ≤500 ns, while standard recovery diodes exceed 500 ns. The main part ES1A-E3/5AT has 25 ns reverse recovery time (fast recovery). GF1A has 2000 ns reverse recovery time (standard recovery). Fast recovery characteristics reduce switching losses and are preferred in high-frequency applications. Standard recovery diodes are suitable for lower-frequency rectification applications.

Q: Can ES1A and S1A from YAGEO be used interchangeably with ES1A-E3/5AT?

A: Both ES1A and S1A are listed as manufacturer-recommended alternatives with 50 V reverse voltage ratings and Active product status. However, limited detailed electrical specifications are provided in the reference data. Forward voltage specifications differ slightly (950 mV for ES1A and 1100 mV for S1A versus 920 mV for the main part). Complete electrical characteristic verification is necessary before selection for critical applications.

Q: What packaging options are available for these substitutes?

A: All listed substitute parts use the DO-214AC (SMA) surface mount package, matching the main part ES1A-E3/5AT. Packaging variations include Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® formats, which are supply and handling options rather than physical package differences. The component footprint and soldering requirements remain identical across all substitutes.
