SS16 Schottky Diode 60V 1A DO-214AC Equivalent & Substitute Parts

Part Overview

The SS16 is a Schottky rectifier diode rated for 60V reverse voltage and 1A average rectified current in a surface mount DO-214AC (SMA) package. This component is classified as obsolete, necessitating identification of active equivalent and substitute parts for new designs and production continuity. Equivalent parts maintain identical electrical specifications and package form factors, while substitute parts offer compatible performance within the same voltage and current class with potential variations in forward voltage, leakage current, or temperature range.

Current - Average Rectified (Io): 1A minimum
Package / Case: DO-214AC (SMA) surface mount
Technology: Schottky rectifier diode
Mounting Type: Surface Mount

Allowable Variations:

Voltage - Forward (Vf) (Max) @ If: Acceptable range 510 mV to 720 mV @ 1A
Current - Reverse Leakage @ Vr: Acceptable range 50 µA to 500 µA @ 60V

Engineering Selection Recommendations

Direct Equivalents (onsemi Manufacturer):

MBRA160T3G and SS16T3G are active onsemi products that directly replace the obsolete SS16. Both maintain 60V/1A specifications and DO-214AC packaging. MBRA160T3G offers improved forward voltage performance (510 mV vs. 700 mV) and lower leakage current (200 µA), making it the preferred onsemi equivalent. SS16T3G maintains identical forward voltage to the original SS16 (720 mV) and is suitable for designs with established thermal budgets. Both parts are ROHS3 compliant and have unlimited moisture sensitivity rating (MSL 1).

Cross-Manufacturer Equivalents (1A Rating):

STPS1L60A (STMicroelectronics) provides the lowest forward voltage (570 mV @ 1A) and lowest reverse leakage current (50 µA @ 60V) among 1A-rated substitutes. This part is suitable for applications requiring minimal power dissipation and leakage performance. B160-13-F (Diodes Incorporated) matches the original SS16 forward voltage specification (700 mV @ 1A) and extends the lower operating temperature to -65°C, matching the original part's temperature range. B160Q-13-F is the automotive-qualified variant (AEC-Q101) of B160-13-F, suitable for automotive and harsh environment applications.

Higher Current Alternatives (2A and 3A Ratings):

B260A-13-F and B260AQ-13-F (2A rating) and B360A-13-F and B360AM-13-F (3A rating) are suitable for applications requiring higher current capacity while maintaining 60V reverse voltage and DO-214AC packaging. These parts provide design margin for thermal and current handling. B260AQ-13-F and B360AM-13-F carry automotive qualification (AEC-Q101). CDBA260-HF (Comchip Technology, 2A rating) offers an alternative 2A source with active product status.

Compliance and Certification:

All listed substitute parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control. Moisture sensitivity level is MSL 1 (unlimited) for all parts, indicating no special moisture handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can MBRA160T3G or SS16T3G be used as direct replacements for SS16 in existing designs?

A: Yes. Both parts maintain the 60V/1A electrical specifications and DO-214AC package form factor required for SS16 replacement. MBRA160T3G is preferred due to lower forward voltage (510 mV vs. 700 mV), which reduces power dissipation. SS16T3G maintains the original forward voltage specification (720 mV) and is suitable if thermal design is based on the original SS16 characteristics. Both are active products with extended operating temperature ranges (-55°C to 150°C vs. -65°C to 125°C).

Q: What is the difference between B160-13-F and B160Q-13-F?

A: Both parts are Diodes Incorporated 60V/1A Schottky diodes in DO-214AC packaging with identical electrical specifications (700 mV forward voltage @ 1A). B160Q-13-F includes automotive qualification (AEC-Q101) and is supplied in Tape & Reel packaging, while B160-13-F is supplied in Cut Tape & Digi-Reel packaging. Selection depends on packaging requirements and automotive qualification necessity.

Q: When should higher current-rated parts (B260A-13-F, B360A-13-F) be used instead of 1A equivalents?

A: Higher current-rated parts are selected when circuit design requires additional current margin or when thermal analysis indicates the 1A rating is insufficient for the application. These parts maintain the same 60V reverse voltage and DO-214AC package, allowing direct physical substitution. However, circuit board thermal design and PCB copper area must be evaluated for the higher current capability.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements equivalent to the original SS16.

Q: What is the significance of reverse leakage current variation among substitute parts?

A: Reverse leakage current ranges from 50 µA (STPS1L60A) to 500 µA (B160-13-F, B260A-13-F, B360A-13-F, CDBA260-HF) at 60V. Lower leakage current reduces standby power consumption and heat generation in applications with sustained reverse bias. The original SS16 specifies 200 µA, placing it in the mid-range. Selection depends on application power budget and thermal constraints.

Q: Can STPS1L60A be used in all SS16 applications?

A: STPS1L60A is electrically compatible with SS16 for 60V/1A applications and offers superior performance characteristics (570 mV forward voltage, 50 µA leakage current). However, the operating temperature range is -55°C to 150°C (vs. SS16's -65°C to 125°C). Verify that the application's minimum operating temperature requirement does not exceed -55°C before selection.

Q: What packaging options are available for substitute parts?

A: Substitute parts are supplied in Cut Tape (CT) & Digi-Reel or Tape & Reel (TR) packaging. Cut Tape & Digi-Reel packaging is suitable for lower-volume production and manual assembly. Tape & Reel packaging is required for automated pick-and-place assembly. Verify packaging compatibility with assembly equipment and production volume requirements before part selection.
