SS26T3 Schottky Power Diode Equivalent & Substitute Parts

Part Overview

The SS26T3 is a Schottky power diode manufactured by onsemi, rated for 60 V DC reverse voltage and 2 A average rectified current in a Surface Mount SMB (DO-214AA) package. This component is classified as obsolete, which necessitates identification of equivalent and substitute parts for ongoing design support and procurement continuity. The part exhibits fast recovery characteristics with reverse recovery time ≤ 500 ns at currents > 200 mA, making it suitable for high-frequency rectification applications. Equivalent parts maintain identical electrical specifications, while substitute parts provide functional equivalence within acceptable parameter tolerances for the Schottky diode category.

Substitute Part Grouping Explanation

Substitution of the SS26T3 is determined by equivalence in the following critical parameters: maximum reverse voltage (60 V), average rectified current (2 A), fast recovery speed characteristic (≤ 500 ns), and surface mount technology. Parts are grouped into two categories based on package compatibility:

Category 1: Direct Package Equivalents (DO-214AA / SMB) Parts maintaining the identical DO-214AA (SMB) package form factor allow direct board-level substitution without layout modification. These include SS26T3G (onsemi, active status) and SS26-E3/52T (Vishay, active status).

Category 2: Functional Equivalents (Alternative Packages) Parts meeting all electrical specifications but utilizing different surface mount packages (SOD-128) provide functional equivalence with potential layout considerations. These include PMEG6020EP,115 and PMEG6020ETP,115 (both Nexperia USA Inc., active status).

Substitution logic prioritizes: (1) voltage and current ratings, (2) recovery speed classification, (3) package compatibility, (4) product status (active preferred over obsolete), and (5) RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SS26T3G (onsemi)

SS26T3G is the direct equivalent of SS26T3, maintaining identical electrical specifications (60 V, 2 A, 630 mV forward voltage, fast recovery ≤ 500 ns) and package form factor (DO-214AA / SMB). This part is manufactured by the same supplier (onsemi) and carries active product status with ROHS3 compliance. SS26T3G is the preferred substitution path for direct replacement without design modification. Inventory availability is substantial at 35,300 pieces.

Secondary Recommendation: SS26-E3/52T (Vishay General Semiconductor)

SS26-E3/52T provides functional equivalence with identical voltage and current ratings in the same DO-214AA (SMB) package. This part is manufactured by Vishay and maintains active product status with ROHS3 compliance. Forward voltage is specified at 700 mV @ 2 A (70 mV higher than SS26T3), and reverse leakage current is 400 µA @ 60 V (200 µA higher than SS26T3). These parameter differences remain within acceptable tolerances for Schottky diode applications. Operating temperature range is -65°C to 125°C. Inventory availability is 24,539 pieces.

Alternative Recommendation: PMEG6020EP,115 or PMEG6020ETP,115 (Nexperia USA Inc.)

PMEG6020EP,115 and PMEG6020ETP,115 provide functional equivalence with identical voltage and current ratings but utilize the SOD-128 package instead of DO-214AA (SMB). These parts are manufactured by Nexperia USA Inc. and carry active product status with ROHS3 compliance. Forward voltage is specified at 530 mV @ 2 A (100 mV lower than SS26T3), and reverse leakage current is 150 µA @ 60 V (50 µA lower than SS26T3). PMEG6020ETP,115 includes specified reverse recovery time of 8.6 ns and maximum junction temperature of 175°C. These parts require board layout modification due to package change. Inventory availability is 23,838 pieces (PMEG6020EP,115) and 11,008 pieces (PMEG6020ETP,115).

Compliance Consideration

The SS26T3 is RoHS non-compliant. All substitute parts (SS26T3G, SS26-E3/52T, PMEG6020EP,115, PMEG6020ETP,115) are ROHS3 compliant, supporting transition to current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can SS26T3G be used as a direct replacement for SS26T3?

A: Yes. SS26T3G is the direct equivalent, maintaining identical electrical specifications (60 V reverse voltage, 2 A average rectified current, 630 mV forward voltage @ 2 A, fast recovery ≤ 500 ns) and package form factor (DO-214AA / SMB). No design modification is required.

Q: What is the difference between SS26T3G and SS26-E3/52T?

A: Both parts share the same package (DO-214AA / SMB) and voltage/current ratings (60 V, 2 A). SS26T3G is manufactured by onsemi with 630 mV forward voltage and 200 µA reverse leakage. SS26-E3/52T is manufactured by Vishay with 700 mV forward voltage and 400 µA reverse leakage. The Vishay part exhibits higher forward voltage drop and reverse leakage current but remains functionally equivalent within Schottky diode tolerances.

Q: Can PMEG6020EP,115 or PMEG6020ETP,115 replace SS26T3 without board modification?

A: No. PMEG6020EP,115 and PMEG6020ETP,115 utilize the SOD-128 package, which differs from the DO-214AA (SMB) package of SS26T3. Board layout modification is required for these substitutes. However, electrical specifications are equivalent (60 V, 2 A, fast recovery ≤ 500 ns).

Q: What are the key electrical differences between substitute parts?

A: Forward voltage varies: SS26T3 and SS26T3G specify 630 mV @ 2 A, PMEG6020 series specifies 530 mV @ 2 A, and SS26-E3/52T specifies 700 mV @ 2 A. Reverse leakage current varies: SS26T3 and SS26T3G specify 200 µA @ 60 V, PMEG6020 series specifies 150 µA @ 60 V, and SS26-E3/52T specifies 400 µA @ 60 V. All parts maintain identical voltage and current ratings and fast recovery characteristics.

Q: Are all substitute parts RoHS compliant?

A: Yes. SS26T3G, SS26-E3/52T, PMEG6020EP,115, and PMEG6020ETP,115 are all ROHS3 compliant. The original SS26T3 is RoHS non-compliant. Substitution supports compliance with current regulatory requirements.

Q: Which substitute part has the lowest forward voltage drop?

A: PMEG6020EP,115 and PMEG6020ETP,115 specify 530 mV @ 2 A forward voltage, which is 100 mV lower than SS26T3 (630 mV @ 2 A). Lower forward voltage drop reduces power dissipation in rectification applications.

Q: What is the moisture sensitivity level for all parts?

A: All parts, including SS26T3, SS26T3G, SS26-E3/52T, PMEG6020EP,115, and PMEG6020ETP,115, are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.

Q: Are there operating temperature differences between substitute parts?

A: Yes. SS26T3G does not specify a maximum junction temperature in the provided data. SS26-E3/52T specifies -65°C to 125°C operating temperature range. PMEG6020EP,115 specifies 150°C maximum junction temperature. PMEG6020ETP,115 specifies 175°C maximum junction temperature. Temperature ratings should be verified against application requirements.
