SS13FP Schottky Diode Equivalent & Substitute Parts

Part Overview

The SS13FP is a 30V, 1A Schottky rectifier diode manufactured by onsemi in SOD-123HE surface mount packaging. This component is classified as Not For New Designs, indicating it has been superseded in the manufacturer's product portfolio. The diode is qualified to AEC-Q101 automotive standards and features fast recovery characteristics suitable for rectification and switching applications requiring low forward voltage drop.

Identification of equivalent and substitute parts is necessary for applications where the SS13FP is no longer available through standard distribution channels or where design flexibility permits the use of functionally compatible alternatives that meet the same electrical and mechanical requirements.

The SS1P3LHM3/84A manufactured by Vishay General Semiconductor - Diodes Division meets all electrical and compliance requirements for substitution with the SS13FP.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SS13FP carries a Not For New Designs designation, indicating onsemi has discontinued active development and marketing of this component. The SS1P3LHM3/84A maintains Active product status, ensuring continued availability and manufacturer support.

Compliance and Certification: Both components hold AEC-Q101 qualification and ROHS3 compliance, meeting automotive and environmental regulatory requirements. Both components feature MSL 1 (Unlimited) moisture sensitivity classification, permitting standard handling and storage procedures without desiccant requirements.

Electrical Performance: The SS1P3LHM3/84A demonstrates equivalent or superior electrical characteristics across all measured parameters. Forward voltage drop is reduced by 50 mV at rated current, and reverse leakage current is reduced by 50%, indicating improved efficiency and lower standby power consumption. The increased junction capacitance of 30 pF is within acceptable tolerance for most rectification and switching applications.

Package Compatibility: The SS1P3LHM3/84A uses DO-220AA (SMP) packaging, which differs from the SS13FP SOD-123H package. PCB footprint redesign is required for direct substitution. Component placement and thermal management characteristics must be evaluated for the specific application.

Frequently Asked Questions (FAQ)

Q: Can the SS1P3LHM3/84A directly replace the SS13FP without PCB modification?

A: No. The SS13FP uses SOD-123H packaging while the SS1P3LHM3/84A uses DO-220AA (SMP) packaging. These packages have different physical dimensions and footprint patterns. PCB redesign is required for component placement and soldering.

Q: Are there electrical performance differences between these components?

A: The SS1P3LHM3/84A exhibits lower forward voltage drop (450 mV versus 500 mV at 1 A) and lower reverse leakage current (200 µA versus 400 µA at 30 V). These differences result in improved efficiency and reduced power dissipation. Junction capacitance is higher by 30 pF, which may affect high-frequency switching performance in specific circuit topologies.

Q: Do both components meet automotive qualification requirements?

A: Yes. Both the SS13FP and SS1P3LHM3/84A hold AEC-Q101 qualification and are classified as Automotive grade components. Both are ROHS3 compliant and feature MSL 1 moisture sensitivity classification.

Q: What is the significance of the SS13FP being marked Not For New Designs?

A: This designation indicates that onsemi has concluded the active product lifecycle for the SS13FP. While existing inventory may remain available, the manufacturer does not recommend this component for new circuit designs. The SS1P3LHM3/84A with Active status is the appropriate selection for new applications.

Q: Are there thermal operating range differences?

A: No. Both components operate across the identical junction temperature range of -55°C to 150°C, supporting the same thermal environment specifications.

Q: How do the reverse voltage ratings compare?

A: Both components are rated for 30 V maximum reverse bias voltage. They are functionally equivalent in this parameter and suitable for identical circuit voltage specifications.

Q: What is the significance of the Fast Recovery speed classification?

A: Both components meet the Fast Recovery specification of ≤ 500ns recovery time at currents greater than 200 mA. This classification indicates suitability for switching applications and rectification circuits requiring rapid diode turn-off characteristics.
