Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ES2D-LTP are grouped based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 200 V (exact match required)
• Package / Case: DO-214AC, SMA (mechanical and electrical interface compatibility)
• Mounting Type: Surface Mount (assembly process compatibility)
• Technology: Standard (process node equivalence)
• RoHS Status: ROHS3 Compliant (regulatory compliance)

Secondary Consideration:

• Current - Average Rectified (Io): Parts rated at 2 A provide direct substitution; parts rated below 2 A (1 A or 1.5 A) are listed as alternatives where current requirements permit

All substitute parts listed maintain the 200 V reverse voltage rating and surface mount SMA package, ensuring pin-compatible replacement. Differences in forward voltage, reverse recovery time, and reverse leakage current are documented to enable informed selection based on circuit performance requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (2 A Current Rating):

ES2DA-13-F (Diodes Incorporated) and STTH2R02A (STMicroelectronics) are direct current-rated substitutes for the ES2D-LTP. Both maintain 200 V reverse voltage and 2 A average rectified current specifications. ES2DA-13-F exhibits lower forward voltage (920 mV vs. 950 mV) and faster reverse recovery time (25 ns vs. 35 ns), with operating temperature range of -55°C to 150°C. STTH2R02A provides lower reverse leakage current (3 µA vs. 5 µA) and faster reverse recovery time (30 ns), with maximum junction temperature of 175°C.

Current-Limited Alternatives (1 A to 1.5 A Rating):

ES1DH (Taiwan Semiconductor Corporation), STTH102A, STTH102AY, and STTH1R02A are suitable where circuit design permits reduced current ratings. ES1DH is rated for 1 A with identical forward voltage and reverse recovery time to the main part. STTH102A and STTH102AY (STMicroelectronics) are 1 A devices with superior reverse leakage characteristics (1 µA vs. 5 µA) and faster recovery time (20 ns). STTH102AY includes automotive-grade qualification and extended temperature range (-40°C to 175°C). STTH1R02A provides intermediate 1.5 A current rating with lower reverse leakage (3 µA) and faster recovery time (30 ns).

Compliance Status:

All listed substitute parts maintain ROHS3 compliance, RoHS Unaffected REACH status, and EAR99 export classification, matching the regulatory profile of the ES2D-LTP.

Frequently Asked Questions (FAQ)

Q: Can ES2DA-13-F replace ES2D-LTP in all applications?

A: ES2DA-13-F is a direct current-rated substitute with identical 200 V and 2 A specifications. The lower forward voltage (920 mV vs. 950 mV) and faster reverse recovery time (25 ns vs. 35 ns) represent improved performance characteristics. Operating temperature range differs (-55°C to 150°C vs. -65°C to 175°C); verify application temperature requirements before selection.

Q: What is the difference between STTH102A and STTH102AY?

A: Both parts are 1 A, 200 V rectifier diodes with identical electrical specifications. STTH102AY includes automotive-grade qualification and extended operating temperature range (-40°C to 175°C) compared to STTH102A (175°C maximum). Select STTH102AY for automotive applications requiring grade certification.

Q: Can 1 A rated diodes substitute for the 2 A ES2D-LTP?

A: 1 A rated diodes (ES1DH, STTH102A, STTH102AY) are functional substitutes only where circuit design permits reduced current capacity. These parts maintain 200 V reverse voltage and surface mount SMA package compatibility. Circuit analysis must confirm that peak and average current demands do not exceed 1 A ratings.

Q: Are all substitute parts available in the same packaging?

A: All substitute parts use DO-214AC (SMA) surface mount package, ensuring mechanical and electrical interface compatibility. Packaging format differs: ES2D-LTP and STTH series are supplied in Cut Tape (CT); ES2DA-13-F and ES1DH are supplied in Tape & Reel (TR). Verify packaging requirements for assembly process compatibility.

Q: What is the significance of reverse recovery time differences?

A: Reverse recovery time (trr) affects switching speed and switching losses in high-frequency applications. ES2D-LTP has 35 ns trr; ES2DA-13-F has 25 ns; STTH series devices have 20-30 ns. Lower trr values reduce switching losses and enable higher frequency operation. Select based on circuit switching frequency requirements.

Q: Do all parts meet the same temperature range as ES2D-LTP?

A: No. ES2D-LTP operates from -65°C to 175°C. ES2DA-13-F and ES1DH operate from -55°C to 150°C. STTH102A and STTH1R02A specify 175°C maximum only. STTH102AY operates from -40°C to 175°C. Verify application temperature extremes before substitution.
