STPS130AFN Equivalent & Substitute Parts Reference

Part Overview

The STMicroelectronics STPS130AFN is a Schottky diode, rated for 30 V reverse voltage and 1 A average rectified current, in a DO-221AC, SMA Flat package. Its fast recovery speed and surface-mount format suit power rectification applications. As the product status is obsolete, sourcing direct replacements is critical for ongoing designs and inventory support. Selecting substitutes enables engineering continuity while preserving electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is confirmed by matching the following key electrical and mechanical parameters: Schottky technology, maximum reverse voltage (30 V), average rectified current (1 A), forward voltage rating (550 mV @ 1 A), fast recovery speed, reverse leakage characteristics at the stated voltage, operating junction temperature, surface mount format, and package constraints (SMA family). Moisture Sensitivity Level, REACH status, ECCN, and HTS codes must also align for proper compliance.

Parameter Comparison

Engineering Selection Recommendations

The STPS130AFN is obsolete. The STPS130A is active, meets ROHS3 requirements, and maintains identical core electrical parameters. Both parts satisfy compliance criteria, including REACH unaffected status, Moisture Sensitivity Level 1 (unlimited), ECCN EAR99, and HTSUS code 8541.10.0080. The substitute features an SMA package variation; mechanical compatibility should be validated with respect to PCBA land pattern constraints.

Frequently Asked Questions (FAQ)

Q1: Which parameters require strict matching for Schottky diode substitution?
Critical parameters include technology type, reverse voltage, average rectified current, forward voltage drop at rated current, switching recovery speed, reverse leakage current, and junction operating temperature. Package type must also be compatible with the PCB footprint.

Q2: Are there notable differences in the packaging between STPS130AFN and STPS130A?
STPS130AFN uses DO-221AC (SMA Flat Leads), while STPS130A utilizes DO-214AC (SMA). Both are surface mount packages in the SMA family but differ in mechanical details. Ensure matching PCB land pattern and clearance.

Q3: Does compliance status differ between the main and substitute part?
Both diodes are REACH unaffected and have MSL 1 (unlimited), with matching ECCN and HTSUS codes. The substitute STPS130A is ROHS3 compliant.

Q4: How does reverse leakage specification compare between the main and substitute?
STPS130AFN specifies 10 mA @ 30 V; STPS130A specifies 10 µA @ 30 V.

Q5: What is the recommended approach for selecting a substitute in the "Diodes, Rectifiers" category?
Substitute selection is based on exact parameter matching for electrical, compliance, and mechanical attributes within the allowed values for Schottky diodes, reverse voltage, current, forward drop, package style, and regulatory certifications.
