Primary Equivalence Criteria:

Voltage - DC Reverse (Vr) (Max): 30 V
Current - Average Rectified (Io): 1 A
Package / Case: DO-214AC, SMA
Mounting Type: Surface Mount
Technology: Schottky
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Acceptable Variation Parameters:

Voltage - Forward (Vf) (Max) @ If: ±100 mV tolerance
Current - Reverse Leakage @ Vr: ±800 µA tolerance
Operating Temperature - Junction: Minimum -55°C, Maximum ≥125°C

Parts are grouped into three categories:

Parametric Equivalents (Vishay): Identical specifications with different packaging configurations (Tape & Reel variants). These are direct replacements from the same manufacturer base product line (SS13 series).
Manufacturer Recommended Equivalents (Cross-Manufacturer): Parts from Diodes Incorporated, onsemi, and STMicroelectronics that meet or exceed the primary equivalence criteria with minor variations in forward voltage or reverse leakage within acceptable tolerances.
Functional Substitutes (Higher Current Rating): The STPS2L30A provides 2 A current rating while maintaining 30 V reverse voltage, suitable for applications requiring additional current margin.

Engineering Selection Recommendations

Direct Replacement (Parametric Equivalents):

The Vishay SS13 series variants (SS13-E3/5AT, SS13-E3/61T, SS13-M3/5AT, SS13-M3/61T) are parametric equivalents with identical electrical specifications. These parts are active products and provide direct substitution. Selection among these variants depends on packaging preference: 5AT and 5AT designations indicate different tape configurations, while 61T designations indicate alternative reel specifications. All variants maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Cross-Manufacturer Equivalents:

Diodes Incorporated B130-13-F and B130L-13-F, onsemi MBRA130LT3G, and STMicroelectronics STPS130A, STPS1L30A are active products meeting the 30 V / 1 A specification. These parts exhibit variations in forward voltage drop and reverse leakage current within acceptable tolerances. The B130L-13-F and MBRA130LT3G offer lower forward voltage (410 mV vs. 500 mV), reducing power dissipation in applications with continuous current flow. The STPS1L30A provides the lowest forward voltage (395 mV) with matching reverse leakage to the original part. All cross-manufacturer equivalents maintain ROHS3 compliance and MSL 1 rating.

Higher Current Alternative:

The STMicroelectronics STPS2L30A provides 2 A average rectified current while maintaining 30 V reverse voltage in the same DO-214AC package. This part is suitable for applications requiring additional current margin or where the 1 A rating presents insufficient headroom. Forward voltage at 2 A is specified at 450 mV, and reverse leakage remains at 200 µA @ 30 V.

Temperature Considerations:

The original SS13HE3/5AT specifies maximum junction temperature of 125°C. Diodes Incorporated (B130-13-F, B130L-13-F) and STMicroelectronics (STPS130A, STPS1L30A, STPS2L30A) parts support maximum junction temperatures of 150°C, providing thermal margin in high-temperature environments. onsemi MBRA130LT3G is limited to 125°C maximum junction temperature, matching the original specification.

Frequently Asked Questions (FAQ)

Q: Can SS13-E3/5AT, SS13-E3/61T, SS13-M3/5AT, and SS13-M3/61T be used interchangeably with SS13HE3/5AT?

A: Yes. These Vishay parts are parametric equivalents with identical electrical specifications (30 V, 1 A, 500 mV forward voltage, 200 µA reverse leakage). Differences in part number designations reflect packaging configuration and tape reel specifications only. All are active products suitable for direct replacement.

Q: What is the difference between B130-13-F and B130L-13-F?

A: Both are Diodes Incorporated 30 V / 1 A Schottky diodes in DO-214AC packages. The B130L-13-F features lower forward voltage (410 mV vs. 500 mV) and higher reverse leakage (1 mA vs. 500 µA). The B130-13-F supports higher maximum junction temperature (150°C vs. 125°C). Selection depends on whether forward voltage reduction or thermal headroom is prioritized.

Q: Is STPS1L30A a suitable replacement for SS13HE3/5AT?

A: Yes. The STPS1L30A meets all primary equivalence criteria: 30 V reverse voltage, 1 A average rectified current, DO-214AC package, and fast recovery Schottky technology. It offers lower forward voltage (395 mV vs. 500 mV) and higher maximum junction temperature (150°C vs. 125°C). Reverse leakage matches the original specification at 200 µA @ 30 V.

Q: Can STPS2L30A be used in place of SS13HE3/5AT?

A: STPS2L30A is a functional substitute with 2 A current rating instead of 1 A. It maintains 30 V reverse voltage and DO-214AC package compatibility. This part is suitable for applications where the 1 A rating is insufficient or where additional current margin is required. Forward voltage at 2 A is 450 mV, and reverse leakage is 200 µA @ 30 V.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All parts listed in this reference maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), meeting current environmental and reliability standards.

Q: What is the significance of the "5AT" and "61T" designations in Vishay part numbers?

A: These designations indicate packaging and tape reel configurations. The "5AT" and "61T" suffixes specify different tape widths and reel diameters for automated assembly equipment. Electrical specifications remain identical across these variants. Selection depends on compatibility with specific pick-and-place equipment and tape feeder configurations.

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

A: The STMicroelectronics STPS1L30A specifies 395 mV forward voltage @ 1 A, the lowest among all listed parts. This reduces power dissipation in applications with continuous current flow. The onsemi MBRA130LT3G and Diodes Incorporated B130L-13-F both specify 410 mV, providing similar performance with slightly higher dissipation than STPS1L30A.

Q: Do all substitute parts use the same DO-214AC package?

A: Yes. All parts listed maintain DO-214AC (SMA) package compatibility, ensuring mechanical and thermal interface equivalence with the original SS13HE3/5AT. This allows direct PCB footprint compatibility without layout modifications.

Q: What is the maximum operating temperature for each substitute part?

A: Vishay SS13 variants and onsemi MBRA130LT3G support -65°C to 125°C junction temperature range. Diodes Incorporated B130-13-F and STMicroelectronics STPS130A, STPS1L30A, and STPS2L30A support -55°C to 150°C or -65°C to 150°C ranges, providing extended high-temperature operation capability.
