STPS2L30AF Equivalent & Substitute Parts

Part Overview

The STPS2L30AF is a Schottky rectifier diode manufactured by STMicroelectronics, rated for 30 V DC reverse voltage and 2 A average rectified current in a surface mount SMA package. This part is classified as obsolete, necessitating identification of active equivalent and substitute components for new designs and ongoing production requirements. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts provide functional alternatives with allowable parameter variations within the same product category.

Substitute Part Grouping Explanation

Substitution of the STPS2L30AF is determined by the following critical parameters: voltage rating (30 V DC reverse), current rating (2 A average rectified), forward voltage characteristics, reverse leakage current, switching speed classification, and surface mount package compatibility. Parts are grouped into two categories:

Parametric Equivalent: Parts maintaining identical electrical specifications across all rated parameters and package form factor.

Similar/Functional Substitute: Parts with the same voltage and current ratings but differing in forward voltage, reverse leakage, package variant (SMA versus SMAF), or operating temperature range. These parts are electrically compatible within the 30 V / 2 A application envelope but require verification of specific circuit requirements.

Current rating variations (1 A, 3 A) represent functional substitutes only for applications where the original 2 A specification can be adjusted. Package variants (DO-214AC SMA versus DO-221AC SMAF) require PCB layout compatibility assessment.

Engineering Selection Recommendations

Primary Recommendation: STPS2L30A (STMicroelectronics) is the direct parametric equivalent to STPS2L30AF. This part maintains identical electrical specifications (30 V, 2 A, 450 mV forward voltage, 200 µA reverse leakage) and package form factor (DO-214AC, SMA). The STPS2L30A is active in production status and ROHS3 compliant, making it the preferred replacement for direct substitution in existing designs.

Secondary Recommendations for 2 A Applications: B230AF-13 (Diodes Incorporated) and SB23AFC_R2_00001 (Panjit International Inc.) both provide 30 V / 2 A Schottky rectification with active product status and ROHS3 compliance. These parts employ the DO-221AC SMAF package variant, requiring PCB layout modification. Forward voltage is specified at 500 mV (versus 450 mV for STPS2L30AF) and reverse leakage is reduced to 100 µA, representing acceptable parameter variations for most rectification applications.

Current Rating Alternatives: B130-13-F and B130AF-13 (1 A rating) and B330AF-13 (3 A rating) are functional substitutes only when circuit design permits current rating adjustment. These parts maintain 30 V voltage rating and fast recovery switching characteristics but differ in current capacity and package configuration.

All recommended substitutes maintain ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and REACH unaffected status, consistent with the original part's regulatory classification.

Frequently Asked Questions (FAQ)

Q: Can STPS2L30A directly replace STPS2L30AF without PCB modification?

A: Yes. STPS2L30A is a parametric equivalent with identical electrical specifications and package form factor (DO-214AC, SMA). No circuit or layout changes are required.

Q: What is the difference between SMA and SMAF package variants?

A: SMA (DO-214AC) and SMAF (DO-221AC, SMA Flat Leads) are distinct surface mount packages with different lead geometries and PCB footprints. SMAF packages feature flat leads and require modified PCB landing patterns. Substitution between these packages requires PCB redesign.

Q: Can B230AF-13 replace STPS2L30AF in a 2 A application?

A: B230AF-13 provides equivalent 30 V / 2 A rectification with active product status. The forward voltage specification differs (500 mV versus 450 mV), and the package is SMAF instead of SMA. Circuit performance remains acceptable for most applications, but PCB layout modification is mandatory.

Q: Why is reverse leakage current different across substitute parts?

A: Reverse leakage current is a manufacturing parameter that varies by semiconductor process and device design. All listed parts maintain leakage within acceptable ranges for Schottky rectifier applications. The STPS2L30AF and B330AF-13 specify 200 µA, while B230AF-13 and SB23AFC_R2_00001 specify 100 µA. Lower leakage values represent improved performance characteristics.

Q: Are B130-13-F and B130AF-13 suitable replacements for STPS2L30AF?

A: These parts are not direct replacements. Both are rated for 1 A average rectified current, compared to 2 A for STPS2L30AF. They are functional substitutes only in applications where the circuit design can accommodate reduced current capacity.

Q: What is the significance of the operating temperature range difference?

A: STPS2L30AF specifies maximum junction temperature of 150°C. Substitute parts from Diodes Incorporated and Panjit specify operating ranges of −55°C to 150°C, providing extended low-temperature performance. This represents an enhancement over the original part specification.

Q: Do all substitute parts meet the same compliance standards as STPS2L30AF?

A: Yes. All listed substitute parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.10.0080, matching the regulatory classification of STPS2L30AF.
