Substitute Part Grouping Explanation

Substitution of the ESH2D R5G is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 200 V
Current - Average Rectified (Io): 2 A
Package / Case: DO-214AA (SMB)
Mounting Type: Surface Mount
Technology: Standard (Fast Recovery)
RoHS Status: ROHS3 Compliant

Parametric Equivalents are parts with identical electrical ratings and packaging. These parts are direct replacements with no design modifications required.

Similar Parts share the same voltage and current ratings and package type but may exhibit variations in forward voltage, reverse recovery time, reverse leakage current, or capacitance within acceptable operating ranges. These parts are suitable substitutes when the application tolerates minor electrical characteristic variations.

Packaging Variants include parts with identical electrical specifications but different surface mount package designations (SMA vs. SMB). These require PCB layout verification before substitution.

Current-Rated Variants (such as MURS120 series at 1 A) do not meet the 2 A current requirement and are not suitable substitutes for applications requiring the full 2 A rating.

Not Recommended for Direct Substitution:

MURS120 series parts (MURS120-13-F and MURS120-E3/52T) are rated for 1 A average rectified current and do not meet the 2 A requirement of the original ESH2D R5G specification. These parts are unsuitable for applications requiring the full 2 A current rating.

Frequently Asked Questions (FAQ)

Q: Can I use ES2D-13-F as a direct replacement for ESH2D R5G?

A: ES2D-13-F is a suitable substitute. Both parts share identical voltage (200 V) and current (2 A) ratings and the same DO-214AA (SMB) package. The forward voltage is slightly higher (920 mV versus 900 mV), and the reverse recovery time is slightly longer (25 ns versus 20 ns). These differences are within acceptable operating ranges for most applications. The operating temperature range of ES2D-13-F is -55°C to 150°C, which is 25°C lower than the original part's maximum junction temperature.

Q: What is the difference between ESH2D and ESH2D R5G?

A: ESH2D and ESH2D R5G are electrically identical parts from Taiwan Semiconductor Corporation. The primary difference is packaging format: ESH2D R5G is supplied in Cut Tape (CT), while ESH2D is supplied in Tape & Reel (TR). Both maintain the same electrical specifications and temperature range (-55°C to 175°C). ESH2D is currently in active product status.

Q: Why are MURS120 parts listed but not recommended?

A: MURS120 series parts are rated for 1 A average rectified current, whereas the ESH2D R5G is rated for 2 A. Using a 1 A part in an application requiring 2 A would result in device overstress and potential failure. These parts do not meet the current requirement and are not suitable substitutes.

Q: Can I use ES2DA-13-F instead of ES2D-13-F?

A: ES2DA-13-F has identical electrical specifications to ES2D-13-F but uses a different surface mount package: DO-214AC (SMA) instead of DO-214AA (SMB). Before substitution, verify that your PCB layout and assembly equipment support the SMA package footprint. The electrical performance is equivalent.

Q: What does AEC-Q101 qualification mean?

A: AEC-Q101 is an automotive industry qualification standard for discrete semiconductors. Parts carrying this qualification (such as ES2DHE3_A/H, ES2DHE3_A/I, and ES2DHE3J_A/H) have undergone additional testing and reliability screening required for automotive applications. These parts are suitable for both automotive and general industrial applications.

Q: How do I choose between ES2DHE3_A/H and ES2DHE3_A/I?

A: Both parts are electrically identical with the same 200 V / 2 A ratings, forward voltage (900 mV), reverse recovery time (20 ns), and AEC-Q101 qualification. The difference is in inventory availability: ES2DHE3_A/H has 32210 units in stock, while ES2DHE3_A/I has 15969 units in stock. Selection should be based on procurement lead time and supply chain requirements.

Q: What is the significance of the operating temperature range difference?

A: The original ESH2D R5G operates from -55°C to 175°C junction temperature. Most active substitutes (ES2D-13-F, ES2DHE3 variants) operate to 150°C maximum. If your application requires operation above 150°C, use ESH2D-M3/5BT, which maintains the -55°C to 175°C range. For applications operating below 150°C, the temperature range difference is not a limiting factor.

Q: Can I use ES2D from Good-Ark Semiconductor?

A: ES2D is a suitable substitute with 200 V / 2 A ratings and DO-214AA (SMB) packaging. However, it exhibits higher forward voltage (950 mV versus 900 mV), longer reverse recovery time (35 ns versus 20 ns), and higher reverse leakage current (10 µA versus 2 µA). These characteristics may affect circuit performance in applications with tight power dissipation or switching speed requirements. Verify circuit compatibility before use.

Q: What does "Fast Recovery ≤ 500ns, > 200mA (Io)" mean?

A: This specification indicates that all listed parts are fast recovery rectifier diodes with reverse recovery time not exceeding 500 nanoseconds when conducting currents greater than 200 milliamps. This classification ensures suitable performance in high-frequency switching applications. All substitute parts meet this specification.
