Substitute Part Grouping Explanation

Substitution of the SS2H9-M3/52T is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 90 V
Current - Average Rectified (Io): 2 A
Package / Case: DO-214AA, SMB
Mounting Type: Surface Mount
Technology: Schottky
Speed: Fast Recovery ≤ 500 ns, > 200 mA (Io)

Substitution Categories:

Parametric Equivalents meet all primary criteria with identical or equivalent electrical performance within specified tolerances. These parts are direct functional replacements with no design modifications required.

Manufacturer Recommended Equivalents meet primary voltage, current, and package criteria but may exhibit variations in secondary parameters such as forward voltage drop or reverse leakage current. These parts are functionally compatible within the specified operating envelope.

Substitution is valid only when the replacement part maintains the same voltage rating, current rating, package form factor, and mounting technology. Deviations in forward voltage, reverse leakage, or operating temperature range do not preclude substitution if the application design accommodates the specified parameter ranges.

Engineering Selection Recommendations

SS2H9-E3/52T and SS2H9-E3/5BT (Vishay General Semiconductor - Diodes Division)

These parts are parametric equivalents of the SS2H9-M3/52T. Both devices share identical voltage ratings (90 V), current ratings (2 A), forward voltage characteristics (790 mV @ 2 A), and operating temperature range (-65 to 175 °C). All three parts are manufactured by Vishay General Semiconductor - Diodes Division, carry ROHS3 compliance, and maintain MSL 1 (Unlimited) moisture sensitivity classification. The SS2H9-E3/52T and SS2H9-E3/5BT differ only in packaging designation (52T and 5BT tape & reel configurations) and represent direct functional replacements with no circuit design modifications required.

SS29 (Taiwan Semiconductor Corporation)

The SS29 is a manufacturer-recommended equivalent that meets the primary voltage (90 V), current (2 A), and package (DO-214AA, SMB) specifications. This part exhibits a higher forward voltage drop (850 mV @ 2 A versus 790 mV @ 2 A) and elevated reverse leakage current (100 µA @ 90 V versus 10 µA @ 100 V). The SS29 operates within a narrower temperature range (-55 to 150 °C versus -65 to 175 °C). The SS29 is suitable for applications where the specified parameter variations fall within design tolerances. ROHS3 compliance and MSL 1 classification are maintained.

All substitute parts are Active product status and carry REACH Unaffected and EAR99 ECCN designations consistent with the main part.

Frequently Asked Questions (FAQ)

Q: Can SS2H9-E3/52T and SS2H9-E3/5BT be used interchangeably with SS2H9-M3/52T?

A: Yes. Both parts are parametric equivalents with identical electrical specifications across voltage rating, current rating, forward voltage, reverse leakage, operating temperature range, and package form factor. The difference between 52T and 5BT designations reflects tape & reel packaging configurations and does not affect electrical performance or circuit compatibility.

Q: What are the key differences between the Vishay parts and the SS29?

A: The SS29 exhibits higher forward voltage (850 mV versus 790 mV at 2 A) and higher reverse leakage current (100 µA versus 10 µA at 90 V). The SS29 also operates within a narrower temperature range (-55 to 150 °C versus -65 to 175 °C). These differences are acceptable for applications where the design accommodates the specified parameter ranges.

Q: Are all substitute parts in the same DO-214AA package?

A: Yes. All parts listed—SS2H9-M3/52T, SS2H9-E3/52T, SS2H9-E3/5BT, and SS29—are packaged in DO-214AA (SMB) surface mount configuration. No PCB layout modifications are required for substitution.

Q: Do all parts meet RoHS and REACH compliance requirements?

A: Yes. All parts are ROHS3 Compliant, REACH Unaffected, and carry EAR99 ECCN classification. Moisture sensitivity level is MSL 1 (Unlimited) for all parts.

Q: What is the difference between the tape & reel packaging codes (52T versus 5BT)?

A: Both 52T and 5BT designations indicate Tape & Reel (TR) packaging. These codes reflect different reel configurations or supplier packaging specifications but do not affect electrical performance, package dimensions, or circuit compatibility.

Q: Can the SS29 be used in applications requiring the full -65 to 175 °C operating range?

A: The SS29 is rated for -55 to 150 °C operation. Applications requiring operation below -55 °C or above 150 °C must use the Vishay parts (SS2H9-M3/52T, SS2H9-E3/52T, or SS2H9-E3/5BT), which are rated to -65 to 175 °C.

Q: Are there any design considerations for forward voltage differences?

A: The SS29 exhibits 60 mV higher forward voltage drop (850 mV versus 790 mV at 2 A). Applications sensitive to forward voltage characteristics or power dissipation should account for this difference in thermal and electrical design calculations.
