SK13 Schottky Diode 30V 1A Equivalent & Substitute Parts

Part Overview

The SK13 is an active Schottky rectifier diode manufactured by Diotec Semiconductor, rated for 30V DC reverse voltage and 1A average rectified current. The device is packaged in DO-214AC (SMA) surface mount configuration and is designed for fast recovery applications with switching speeds ≤500ns at currents >200mA. This component is ROHS3 compliant and maintains an extensive inventory of 30,300 pieces in stock.

Substitute parts are identified when equivalent electrical performance parameters are met within the same functional category, enabling design flexibility and supply chain alternatives while maintaining circuit performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SK13 is determined by matching the following critical electrical parameters:

1. Voltage Rating: Reverse voltage (Vr) must equal or exceed 30V DC maximum
2. Current Rating: Average rectified current (Io) must equal or exceed 1A
3. Technology Type: Schottky diode technology required
4. Recovery Speed: Fast recovery characteristic ≤500ns at currents >200mA
5. Mounting Configuration: Surface mount technology
6. Compliance: ROHS3 compliance required

The PMEG3010BER,115 manufactured by Nexperia USA Inc. satisfies all substitution criteria. While the package format differs (SOD-123W versus DO-214AC), both are surface mount configurations suitable for PCB assembly. The electrical performance parameters—reverse voltage, forward current, recovery speed, and leakage characteristics—fall within acceptable substitution boundaries.

Engineering Selection Recommendations

SK13 (Diotec Semiconductor)

The SK13 remains the primary component selection when DO-214AC (SMA) package footprint is specified in the PCB design. This part maintains active product status with substantial inventory availability (30,300 pieces). ROHS3 compliance and established supply chain positioning support continued use in production environments.

PMEG3010BER,115 (Nexperia USA Inc.)

The PMEG3010BER,115 serves as a functional substitute when SOD-123W package compatibility exists in the circuit design. This part demonstrates superior electrical performance in forward voltage drop (450mV versus 500mV) and reverse leakage current (50µA versus 500µA), both favorable characteristics for power efficiency and leakage minimization. The part carries ROHS3 compliance, REACH Unaffected status, and EAR99 classification. Inventory availability is higher (100,400 pieces), supporting supply chain flexibility.

Both parts maintain equivalent reverse voltage ratings, forward current capacity, recovery speed characteristics, and maximum junction temperature ratings. Selection between these parts depends on PCB layout requirements and package footprint availability rather than electrical performance limitations.

Frequently Asked Questions (FAQ)

Q: Can PMEG3010BER,115 directly replace SK13 on existing PCBs?

A: Direct PCB replacement requires package footprint compatibility. The SK13 uses DO-214AC (SMA) footprint while PMEG3010BER,115 uses SOD-123W footprint. These are different land patterns. Substitution is possible only if the PCB layout accommodates SOD-123W dimensions or if the design is modified to accept the alternative package.

Q: Are the electrical specifications identical between SK13 and PMEG3010BER,115?

A: Both parts meet the core functional requirements: 30V reverse voltage rating, 1A average rectified current, fast recovery Schottky technology, and equivalent maximum junction temperature. The PMEG3010BER,115 exhibits lower forward voltage drop (450mV versus 500mV) and significantly lower reverse leakage current (50µA versus 500µA), representing performance improvements rather than deviations.

Q: What compliance certifications apply to both parts?

A: Both SK13 and PMEG3010BER,115 carry ROHS3 compliance certification. The PMEG3010BER,115 additionally carries REACH Unaffected status and EAR99 export classification. REACH status for SK13 is available upon request from the manufacturer.

Q: How do package differences affect circuit performance?

A: Package differences (DO-214AC versus SOD-123W) affect PCB layout, thermal dissipation characteristics, and assembly processes but do not alter the electrical performance parameters. Both are surface mount packages suitable for automated assembly. Thermal performance depends on PCB copper area and thermal vias, which are design-specific considerations independent of package selection.

Q: Which part should be selected for new designs?

A: Selection depends on PCB footprint requirements and supply chain strategy. For new designs without existing footprint constraints, either part is acceptable. The PMEG3010BER,115 offers superior electrical characteristics (lower forward voltage, lower leakage) and higher inventory availability. The SK13 maintains compatibility with existing DO-214AC designs.

Q: Are there moisture sensitivity considerations for these parts?

A: The SK13 lists Moisture Sensitivity Level as Not Applicable. The PMEG3010BER,115 carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Both parts are suitable for standard storage and handling conditions without special moisture control requirements.
