Substitute Part Grouping Explanation

Substitute parts for the ESH2CHE3_A/I are identified based on strict equivalence across the following critical parameters:

• Voltage Rating: 150 V DC reverse voltage (Vr)
• Current Rating: 2 A average rectified current (Io)
• Forward Voltage: 930 mV maximum at 2 A
• Package: DO-214AA (SMB) surface mount
• Reverse Leakage: 2 µA at 150 V
• Operating Temperature Range: -55°C to 175°C junction temperature
• Automotive Grade: AEC-Q101 qualification
• Technology: Standard rectifier diode

The ESH2C-E3/52T meets all critical electrical and mechanical parameters required for direct substitution. Both parts share the same base product number (ESH2), manufacturer, package type, and core electrical specifications. Differences in reverse recovery time (35 ns versus 25 ns) remain within acceptable tolerance for general-purpose rectification applications where the main part's fast recovery characteristic is not a circuit-critical requirement.

Parameter Comparison

Engineering Selection Recommendations

Both the ESH2CHE3_A/I and ESH2C-E3/52T are active production parts manufactured by Vishay General Semiconductor - Diodes Division with identical compliance certifications. Selection between these parts is based on the following engineering criteria:

ESH2CHE3_A/I is the primary choice when:

• Fast recovery time (25 ns) is a circuit requirement
• Switching frequency or transient response characteristics are performance-critical
• Current inventory availability is not a constraint (744 pieces in stock)

ESH2C-E3/52T is the appropriate substitute when:

• General-purpose rectification applications do not require the faster 25 ns recovery time
• Higher inventory availability is advantageous (10,400 pieces in stock)
• Supply chain continuity or cost optimization is a procurement objective
• The 35 ns reverse recovery time is acceptable for the application

Both parts carry AEC-Q101 automotive qualification, ROHS3 compliance, and REACH unaffected status, making them suitable for automotive and industrial applications with identical regulatory requirements. The 10 ns difference in reverse recovery time does not affect DC rectification performance or thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can ESH2C-E3/52T be used as a direct replacement for ESH2CHE3_A/I in all applications?

A: Yes, for applications where reverse recovery time is not a circuit-critical parameter. Both parts share identical voltage ratings (150 V), current ratings (2 A), forward voltage (930 mV @ 2 A), package type (DO-214AA), and operating temperature range (-55°C to 175°C). The 10 ns difference in reverse recovery time (35 ns versus 25 ns) is acceptable in general-purpose rectification circuits. Applications requiring fast switching or high-frequency operation should retain the ESH2CHE3_A/I.

Q: Are there any package or mounting differences between these parts?

A: No. Both parts use the DO-214AA (SMB) surface mount package with identical mechanical dimensions and land pattern requirements. PCB layout and assembly processes require no modification when substituting between these parts.

Q: Do both parts meet automotive qualification standards?

A: Yes. Both the ESH2CHE3_A/I and ESH2C-E3/52T are qualified to AEC-Q101 automotive standards and carry ROHS3 compliance and REACH unaffected status. They are suitable for automotive and industrial applications with identical regulatory requirements.

Q: What is the difference in reverse recovery time, and does it matter for my application?

A: The ESH2CHE3_A/I has a reverse recovery time of 25 ns, while the ESH2C-E3/52T has 35 ns. Reverse recovery time affects switching speed and is critical in high-frequency switching applications. For DC rectification or low-frequency applications, this 10 ns difference has negligible impact on circuit performance. Consult your circuit design specifications to determine if fast recovery is required.

Q: What is the current inventory status for each part?

A: The ESH2CHE3_A/I has 744 pieces in stock. The ESH2C-E3/52T has 10,400 pieces in stock. Both parts are active production items from Vishay General Semiconductor - Diodes Division.

Q: Are the electrical characteristics identical between these parts?

A: The critical electrical characteristics are identical: 150 V reverse voltage, 2 A average rectified current, 930 mV forward voltage at 2 A, 2 µA reverse leakage at 150 V, and -55°C to 175°C operating temperature range. The only difference is the reverse recovery time specification.
