Engineering Selection Recommendations

Parametric Equivalent (Direct Replacement):

NRVBSS26T3G-VF01 from onsemi provides identical electrical specifications to the SS26T3G with matching forward voltage drop (630 mV @ 2 A) and reverse leakage current (200 µA @ 60 V). This part carries AEC-Q101 automotive qualification, extending its application scope to automotive-grade designs while maintaining the same operating temperature range (-55°C ~ 150°C).

Direct Manufacturer Equivalents (Same Voltage and Current Rating):

SS26-E3/5BT and SS26-E3/52T from Vishay General Semiconductor - Diodes Division maintain the 60 V / 2 A rating with DO-214AA SMB packaging. These parts exhibit higher forward voltage (700 mV @ 2 A) and reverse leakage (400 µA @ 60 V) compared to the SS26T3G, with a reduced upper junction temperature limit of 125°C. Both are available in Tape & Reel and Cut Tape packaging options.

B260-13-F from Diodes Incorporated and CMSH2-60 TR13 PBFREE from Central Semiconductor Corp both meet the 60 V / 2 A specification with DO-214AA SMB packaging. These parts feature 700 mV forward voltage and 500 µA reverse leakage, with extended upper temperature rating to 150°C. Both are RoHS3 compliant with MSL 1 rating.

Higher Current Capacity Alternatives (3 A Rating):

CMSH3-60M TR13 PBFREE, SK36B-LTP, and SK36BH are rated for 3 A average rectified current at 60 V reverse voltage. These parts maintain the DO-214AA SMB package and fast recovery speed specification. The higher current rating permits use in applications requiring greater current capacity without package change. Forward voltage increases to 750 mV @ 3 A due to the higher current rating.

Alternative Package Format (SOD-128):

PMEG6020EP,115 and PMEG6020ETP,115 from Nexperia USA Inc. provide 60 V / 2 A Schottky rectification in SOD-128 package format. These parts feature superior forward voltage performance (530 mV @ 2 A) and lower reverse leakage (150 µA @ 60 V). PMEG6020ETP,115 extends the maximum junction temperature to 175°C. Package substitution requires PCB layout modification and is suitable only when space constraints or thermal requirements justify the design change.

All substitute parts listed maintain RoHS3 compliance, MSL 1 rating, and fast recovery speed specification (≤ 500ns, > 200mA).

Frequently Asked Questions (FAQ)

Q: Can NRVBSS26T3G-VF01 be used as a direct replacement for SS26T3G?

A: Yes. NRVBSS26T3G-VF01 is a parametric equivalent with identical electrical specifications: 60 V reverse voltage, 2 A current rating, 630 mV forward voltage @ 2 A, and 200 µA reverse leakage @ 60 V. The primary difference is AEC-Q101 automotive qualification, which extends application scope without affecting standard industrial use.

Q: What is the difference between the SS26T3G and Vishay SS26-E3/5BT?

A: Both parts are rated 60 V / 2 A in DO-214AA SMB package. The SS26-E3/5BT exhibits higher forward voltage (700 mV vs. 630 mV @ 2 A) and higher reverse leakage (400 µA vs. 200 µA @ 60 V). The Vishay part has a lower maximum junction temperature of 125°C compared to 150°C for the SS26T3G. These differences may affect thermal performance and power dissipation in the application circuit.

Q: Can 3 A rated parts (CMSH3-60M, SK36B-LTP, SK36BH) replace the 2 A SS26T3G?

A: Yes, from an electrical compatibility standpoint. All three parts maintain 60 V reverse voltage rating and DO-214AA SMB packaging. The higher 3 A current rating provides additional design margin and does not create incompatibility with 2 A circuit requirements. Forward voltage increases to 750 mV @ 3 A due to the higher current specification. Thermal dissipation characteristics may differ due to different semiconductor geometry.

Q: Why do PMEG6020 parts use SOD-128 package instead of SMB?

A: PMEG6020EP,115 and PMEG6020ETP,115 employ SOD-128 package format, which differs from the DO-214AA SMB package of the SS26T3G. Package substitution requires PCB layout modification and is not a direct pin-compatible replacement. These parts are suitable only when design constraints permit package change and when the superior forward voltage performance (530 mV @ 2 A) and lower reverse leakage (150 µA @ 60 V) justify the redesign effort.

Q: What is the significance of the forward voltage difference between substitute parts?

A: Forward voltage directly affects power dissipation in the diode. The SS26T3G specifies 630 mV @ 2 A, while alternatives range from 530 mV (PMEG6020 series) to 750 mV (3 A rated parts). At 2 A current, a 70 mV difference represents approximately 140 mW additional dissipation. Circuit thermal design must account for these differences, particularly in high-frequency switching applications or high-ambient-temperature environments.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed in this reference maintain RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the environmental and regulatory status of the SS26T3G.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape and Digi-Reel packaging are supplied on tape but in smaller quantities suitable for manual handling or small-scale assembly. Tape & Reel packaging provides continuous reel format for automated pick-and-place equipment. Both formats contain identical components; the difference is in supply format and handling method. Selection depends on assembly process requirements and order quantity.

Q: Can the SS26T3G be used in automotive applications?

A: The standard SS26T3G is not automotive qualified. For automotive-grade applications, NRVBSS26T3G-VF01 (AEC-Q101 qualified) or SK36BH (AEC-Q101 qualified) are appropriate selections. These parts meet automotive qualification standards while maintaining equivalent electrical performance.
