Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SL13-M3/5AT are qualified based on the following electrical and mechanical parameters:

Mandatory Compatibility Criteria:

• Voltage - DC Reverse (Vr) (Max): 30 V minimum
• Package / Case: DO-214AC (SMA) surface mount
• Mounting Type: Surface Mount
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Current Rating Consideration: The SL13-M3/5AT operates at 1.5 A average rectified current. Substitute parts are acceptable at equal or higher current ratings (1 A minimum, 2 A maximum within this series).

Technology Variation: The main part utilizes Standard rectifier technology. Substitute parts employ Schottky technology, which provides lower forward voltage drop and faster switching characteristics while maintaining the same reverse voltage and package specifications.

All identified substitutes meet the mandatory compatibility criteria and are Active product status with full RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

STPS1L30A Selection: The STPS1L30A is suitable for applications where forward voltage drop optimization is critical. This Schottky diode operates at 1 A average rectified current with a forward voltage of 395 mV @ 1 A, representing a 50 mV reduction compared to the SL13-M3/5AT. The part maintains identical reverse voltage (30 V), package configuration (DO-214AC/SMA), and fast recovery speed specifications. Operating temperature maximum of 150°C exceeds the main part specification. ROHS3 compliance and MSL 1 rating are maintained. This substitute is appropriate for designs where the 1 A current rating is sufficient.

STPS130A Selection: The STPS130A provides the lowest reverse leakage current (10 µA @ 30 V) among available substitutes, compared to 200 µA in the main part. This Schottky device operates at 1 A average rectified current with 30 V reverse voltage in the same DO-214AC/SMA package. Forward voltage is 550 mV @ 1 A. The higher operating temperature maximum (150°C) and full RoHS3 compliance support this selection for leakage-sensitive applications where the 1 A current rating is acceptable.

STPS2L30A Selection: The STPS2L30A accommodates applications requiring higher current capacity. This Schottky diode operates at 2 A average rectified current, exceeding the SL13-M3/5AT specification by 0.5 A. Reverse voltage remains 30 V with DO-214AC/SMA package compatibility. Forward voltage is 450 mV @ 2 A. The 150°C maximum operating temperature and full RoHS3 compliance are maintained. This substitute is appropriate for designs where current headroom or thermal margin is required.

All substitute parts maintain Active product status, full RoHS3 compliance, and MSL 1 (Unlimited) moisture sensitivity rating. Selection between substitutes depends on application-specific requirements for current capacity, forward voltage characteristics, and reverse leakage performance.

Frequently Asked Questions (FAQ)

Q: Can STPS1L30A replace SL13-M3/5AT in all applications?

A: The STPS1L30A is electrically compatible with the SL13-M3/5AT in applications where the average rectified current does not exceed 1 A. Both devices share identical 30 V reverse voltage rating, DO-214AC/SMA package configuration, and fast recovery speed characteristics. The primary difference is the 1 A current limit of the STPS1L30A versus 1.5 A for the main part. Applications operating at currents between 1 A and 1.5 A require the STPS2L30A or main part.

Q: What is the difference between Standard and Schottky technology in these diodes?

A: The SL13-M3/5AT uses Standard rectifier technology with a forward voltage of 445 mV @ 1 A. The substitute parts employ Schottky technology, which exhibits lower forward voltage drop (STPS1L30A: 395 mV @ 1 A; STPS2L30A: 450 mV @ 2 A). Both technologies maintain the same 30 V reverse voltage rating, fast recovery speed (≤ 500ns), and DO-214AC/SMA package. Technology selection depends on application requirements for power dissipation and switching performance.

Q: Are all substitute parts pin-compatible with the SL13-M3/5AT?

A: Yes. All substitute parts use the DO-214AC (SMA) surface mount package, which provides identical pin configuration and footprint compatibility. The STPS130A, STPS1L30A, and STPS2L30A are direct mechanical replacements on PCB layouts designed for the SL13-M3/5AT.

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

A: The STPS130A exhibits 10 µA reverse leakage @ 30 V, compared to 200 µA for the SL13-M3/5AT, STPS1L30A, and STPS2L30A. Lower reverse leakage is beneficial in applications sensitive to leakage current, such as precision analog circuits or high-impedance measurement systems. The choice between parts depends on whether leakage current specification is a design constraint.

Q: Can STPS2L30A be used in place of SL13-M3/5AT?

A: Yes. The STPS2L30A is electrically and mechanically compatible with the SL13-M3/5AT. The 2 A current rating exceeds the 1.5 A specification of the main part, providing additional current capacity. Both devices share 30 V reverse voltage, DO-214AC/SMA package, and fast recovery speed. The STPS2L30A is suitable for applications where current headroom or thermal margin is advantageous.

Q: Are all parts RoHS3 compliant?

A: Yes. The SL13-M3/5AT and all substitute parts (STPS130A, STPS1L30A, STPS2L30A) are ROHS3 Compliant. All parts maintain MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture handling requirements during storage or assembly.

Q: What is the operating temperature range difference between the main part and substitutes?

A: The SL13-M3/5AT operates from -55°C to 125°C junction temperature. The substitute parts (STPS130A, STPS1L30A, STPS2L30A) have a maximum junction temperature of 150°C, providing 25°C additional thermal margin. The lower temperature limit remains -55°C for all parts. Applications operating near the upper temperature limit of the main part benefit from the higher thermal rating of substitute parts.
