Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Voltage Rating: All substitute parts maintain the 30V DC reverse voltage maximum, ensuring compatibility with circuit protection and operational requirements.

Current Capacity: The SL13-E3/5AT is rated for 1.5A average rectified current. Substitute parts are grouped into two categories:

Full Current Equivalents (1.5A): SL13-E3/61T maintains identical 1.5A rating
Reduced Current Substitutes (1.0A to 1.5A): STPS1L30A, SS13, and STPS130A are rated at 1.0A and are suitable only for applications requiring ≤1.0A
Increased Current Substitutes (2.0A): STPS2L30A is rated at 2.0A and provides higher current capacity

Forward Voltage: Forward voltage drop varies across substitutes (395 mV to 550 mV @ rated current). Selection depends on circuit power dissipation and efficiency requirements.

Package Compatibility: All parts use DO-214AC (SMA) surface mount package with identical mechanical footprint and mounting type.

Temperature Range: Operating junction temperature ranges vary. The main part operates -55°C to 125°C; STMicroelectronics parts specify 150°C maximum; Fairchild SS13 specifies -65°C to 125°C.

Compliance: All parts are RoHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification.

Engineering Selection Recommendations

Full Electrical Equivalence: SL13-E3/61T is the direct parametric equivalent to SL13-E3/5AT. Both parts are manufactured by Vishay, share identical electrical specifications (30V, 1.5A, 445 mV forward voltage), and operate across -55°C to 125°C. The only difference is packaging format: SL13-E3/5AT is supplied in Tape & Reel format while SL13-E3/61T is supplied in Cut Tape format. Both are RoHS3 compliant and carry MSL 1 rating.

Cross-Manufacturer Substitutes with Current Derating: STPS1L30A and STPS130A (STMicroelectronics) and SS13 (Fairchild) are rated at 1.0A average rectified current, representing a 33% reduction from the SL13-E3/5AT 1.5A rating. These parts are suitable for applications where circuit current demand does not exceed 1.0A. STPS1L30A offers the lowest forward voltage (395 mV @ 1 A), while STPS130A exhibits the lowest reverse leakage current (10 µA @ 30 V). STMicroelectronics parts specify 150°C maximum junction temperature compared to the main part's 125°C upper limit. All three parts maintain 30V reverse voltage rating and fast recovery characteristics.

Higher Current Substitute: STPS2L30A (STMicroelectronics) is rated at 2.0A average rectified current, providing 33% higher current capacity than the SL13-E3/5AT. This part is suitable for applications requiring current capacity between 1.5A and 2.0A. Forward voltage is 450 mV @ 2 A. All other electrical and compliance parameters align with the main part.

Compliance and Regulatory Status: All substitute parts maintain RoHS3 compliance, REACH unaffected status, and EAR99 ECCN classification, ensuring regulatory compatibility with the original design.

Packaging Considerations: Tape & Reel and Cut Tape formats are suitable for automated assembly processes. Bulk packaging (SS13) is available for manual assembly or lower-volume applications. All parts use identical DO-214AC (SMA) surface mount package with matching mechanical footprint.

Frequently Asked Questions (FAQ)

Q: Can SL13-E3/61T be used as a direct replacement for SL13-E3/5AT?

A: Yes. SL13-E3/61T is a parametric equivalent with identical electrical specifications: 30V reverse voltage, 1.5A average rectified current, 445 mV forward voltage @ 1 A, and -55°C to 125°C operating temperature range. The parts differ only in packaging format (Cut Tape versus Tape & Reel). Both are RoHS3 compliant with MSL 1 rating.

Q: What is the difference between the 1.0A rated substitutes and the original 1.5A part?

A: STPS1L30A, SS13, and STPS130A are rated for 1.0A average rectified current, which is 33% lower than the SL13-E3/5AT 1.5A rating. These parts are suitable only for circuits where the maximum current demand does not exceed 1.0A. Using a 1.0A part in a 1.5A application will result in component overstress and potential failure.

Q: Can STPS2L30A replace SL13-E3/5AT in all applications?

A: STPS2L30A can replace SL13-E3/5AT in applications where the circuit current does not exceed 1.5A. The STPS2L30A is rated for 2.0A, providing additional current margin. All other electrical parameters (30V reverse voltage, fast recovery, surface mount package) are compatible. Forward voltage is 450 mV @ 2 A, which is 5 mV higher than the main part.

Q: What are the forward voltage differences among substitutes, and does this matter?

A: Forward voltage varies across substitutes: STPS1L30A (395 mV @ 1 A), SL13-E3/5AT and SL13-E3/61T (445 mV @ 1 A), STPS2L30A (450 mV @ 2 A), SS13 (500 mV @ 1 A), and STPS130A (550 mV @ 1 A). Higher forward voltage results in greater power dissipation and heat generation. Selection depends on circuit power budget and thermal management requirements. Lower forward voltage reduces power loss and improves efficiency.

Q: Are all substitute parts RoHS3 compliant?

A: SL13-E3/61T, STPS1L30A, STPS130A, and STPS2L30A are explicitly RoHS3 compliant. SS13 (Fairchild) does not specify RoHS status in the provided data. For applications requiring RoHS3 compliance, use only the explicitly compliant parts.

Q: What is the difference in reverse leakage current between STPS130A and other substitutes?

A: STPS130A exhibits 10 µA reverse leakage @ 30 V, which is 20 times lower than the 200 µA specification of the main part and other substitutes. Lower reverse leakage reduces standby current and improves circuit efficiency in low-power applications. However, STPS130A is rated for 1.0A, not 1.5A.

Q: Do all parts use the same surface mount package?

A: Yes. All parts use DO-214AC (SMA) surface mount package with identical mechanical footprint and mounting type. PCB layout and assembly processes require no modification when substituting between these parts.

Q: What is the temperature range difference between manufacturers?

A: The main part (SL13-E3/5AT) and SS13 specify -55°C to 125°C operating junction temperature range. STMicroelectronics parts (STPS1L30A, STPS130A, STPS2L30A) specify 150°C maximum junction temperature without a minimum specification. For applications operating below -55°C, use SS13 or the main part. For applications requiring operation above 125°C, STMicroelectronics parts provide higher temperature capability.

Q: What packaging formats are available?

A: SL13-E3/5AT is supplied in Tape & Reel (TR) format. SL13-E3/61T is supplied in Cut Tape (CT) format. STPS1L30A, STPS130A, and STPS2L30A are supplied in Cut Tape (CT) & Digi-Reel® format. SS13 is supplied in Bulk format. Tape & Reel and Cut Tape formats are suitable for automated assembly. Bulk packaging is suitable for manual assembly or lower-volume applications.
