SS16T3 Equivalent & Substitute Parts

Part Overview

The SS16T3 is a Schottky rectifier diode rated for 60 V DC reverse voltage and 1 A average rectified current in a surface mount SMA package (DO-214AC). This component is classified as obsolete by the manufacturer onsemi. Due to its obsolete status, direct replacement with active production equivalents is necessary for new designs and ongoing procurement. The substitute parts listed maintain electrical and mechanical compatibility while offering active product status and improved availability.

Substitute Part Grouping Explanation

Substitute parts for the SS16T3 are classified into three categories based on electrical and mechanical parameter alignment:

Direct Manufacturer Equivalents (onsemi): Parts that maintain identical electrical specifications and package format while offering active product status and improved compliance. These parts share the same base product number (SS16) or equivalent series designation.

Parametric Equivalents (onsemi Automotive Grade): Parts that meet all core electrical parameters (60 V, 1 A, SMA package) with automotive qualification (AEC-Q101). These components are suitable for applications requiring automotive-grade reliability.

Similar Cross-Manufacturer Parts (Diodes Incorporated, Vishay): Parts from alternative manufacturers that match the primary electrical specifications (60 V reverse voltage, 1 A average rectified current, fast recovery Schottky technology) and package format. Minor variations in forward voltage, reverse leakage current, or capacitance may exist within acceptable engineering tolerances.

Engineering Selection Recommendations

Primary Recommendation - Direct Equivalent: SS16T3G is the direct active equivalent from onsemi. This part maintains identical electrical specifications to the obsolete SS16T3 while offering ROHS3 compliance and active production status. Selection of SS16T3G eliminates design risk and maintains full backward compatibility.

Automotive Applications: For applications requiring automotive-grade qualification, SBRA8160NT3G or SBRA8160T3G-VF01 are specified. Both parts carry AEC-Q101 qualification and maintain the same electrical parameters as the original SS16T3. These parts are suitable for automotive and high-reliability applications.

Cross-Manufacturer Alternatives: B160-13-F (Diodes Incorporated) and B160-E3/5AT or B160-E3/61T (Vishay General Semiconductor) provide functional equivalence with active product status and ROHS3 compliance. These parts meet the core electrical requirements (60 V, 1 A, Schottky, fast recovery, SMA package). Minor parameter variations exist: B160-13-F exhibits 700 mV forward voltage and 500 µA reverse leakage; Vishay B160 variants show 750 mV forward voltage but maintain 200 µA reverse leakage. These variations remain within acceptable operating margins for most applications.

Higher Current Alternatives: B260A-13-F, B260AQ-13-F, B360A-13-F, and B360AQ-13-F provide increased current ratings (2 A and 3 A respectively) while maintaining 60 V reverse voltage and SMA package format. These parts are suitable for applications requiring higher current capacity than the 1 A specification of SS16T3.

Frequently Asked Questions (FAQ)

Q: Can SS16T3G be used as a direct replacement for SS16T3? A: Yes. SS16T3G is the active production equivalent from onsemi with identical electrical specifications (60 V, 1 A, 720 mV forward voltage, 200 µA reverse leakage) and the same SMA package. The primary differences are active product status and ROHS3 compliance.

Q: What is the difference between SS16T3G and the automotive-grade SBRA8160NT3G? A: Both parts share identical electrical specifications. SBRA8160NT3G carries AEC-Q101 automotive qualification and is designated for automotive and high-reliability applications. SS16T3G is suitable for general industrial and commercial applications. Selection depends on application requirements.

Q: Are Diodes Incorporated B160-13-F and Vishay B160-E3/61T fully compatible with SS16T3? A: These parts are functionally compatible for most applications. All three maintain 60 V reverse voltage, 1 A average rectified current, fast recovery Schottky technology, and SMA package format. Minor differences exist: B160-13-F shows 700 mV forward voltage and 500 µA reverse leakage; B160-E3/61T shows 750 mV forward voltage but 200 µA reverse leakage. These variations are within acceptable engineering tolerances for standard rectification applications.

Q: Can B260A-13-F (2 A) or B360A-13-F (3 A) be used instead of SS16T3 (1 A)? A: Yes, higher-rated parts can be used in place of lower-rated parts when the application circuit does not exceed the original 1 A specification. The higher current rating provides design margin and does not degrade performance. However, the reverse is not true: a 1 A part cannot replace a 2 A or 3 A requirement.

Q: What does RoHS3 compliance mean for SS16T3 substitution? A: RoHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead and other hazardous materials. The original SS16T3 is RoHS non-compliant. All recommended substitutes are ROHS3 compliant, making them suitable for applications with environmental or regulatory requirements.

Q: Does package format matter when selecting a substitute? A: Yes. All recommended substitutes use the DO-214AC (SMA) surface mount package, which is mechanically and electrically compatible with SS16T3. Package compatibility ensures proper PCB footprint alignment and thermal performance. Do not substitute with parts using different package formats.

Q: What is the significance of "Fast Recovery ≤ 500ns, > 200mA (Io)" specification? A: This specification defines the diode's switching speed and is critical for rectification performance. All substitute parts maintain this specification, ensuring equivalent switching characteristics and preventing performance degradation in high-frequency or switching applications.

Q: Are there inventory considerations when selecting a substitute? A: Yes. SS16T3G offers 24,201 pieces in stock; SBRA8160NT3G offers 23,100 pieces; B160-13-F offers 245,300 pieces; and B160-E3/61T offers 1,538 pieces. Availability varies by supplier and part selection. Verify current inventory status with your component supplier before final part selection.
