S100 Schottky Diode 100V 1A DO-214AC Equivalent & Substitute Parts

Part Overview

The onsemi S100 is a Schottky rectifier diode rated for 100V reverse voltage and 1A average rectified current in a DO-214AC (SMA) surface mount package. This component is classified as "Not For New Designs," indicating it has reached end-of-life status. The S100 operates across a junction temperature range of -65°C to 125°C and exhibits fast recovery characteristics suitable for switching applications. Due to its obsolete status, identifying functionally equivalent active alternatives is necessary for ongoing production support and new design implementations.

Substitute Part Grouping Explanation

Substitution of the S100 is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 100V minimum
Current - Average Rectified (Io): 1A minimum
Technology: Schottky
Package / Case: DO-214AC, SMA
Mounting Type: Surface Mount
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Secondary Compatibility Factors:

Forward voltage (Vf) at 1A: Acceptable range 770–850 mV
Reverse leakage current: Acceptable range 1–500 µA @ rated voltage
Operating temperature range: Minimum -65°C to 125°C
RoHS3 compliance and MSL 1 rating

Substitute parts are grouped into two categories:

Category A – Direct Equivalents (100V, 1A, Active Status): Parts meeting all primary criteria with active product status and full parameter alignment. These include B1100-13-F, B1100Q-13-F, MS110_R1_00001, SS110, SS1H10-E3/61T, STPS1H100A, STPS1H100AY.

Category B – Voltage-Reduced Alternatives (70V–80V, 1A, Active Status): Parts meeting all primary criteria except reverse voltage rating. These include B170-13-F (70V) and B180-13-F (80V). These are suitable only for applications with maximum reverse voltage requirements below 80V.

Category C – Obsolete Alternatives: SS110-TP (Micro Commercial Co) shares identical electrical specifications but carries obsolete product status, limiting its use to legacy system support only.

Frequently Asked Questions (FAQ)

Q: Can I use a 70V or 80V rated diode (B170-13-F or B180-13-F) as a direct replacement for the S100?

A: No. The S100 is rated for 100V reverse voltage. Substituting a lower-voltage diode creates risk of diode failure if reverse voltage exceeds the substitute part's rating. Use B170-13-F or B180-13-F only in applications where the maximum reverse voltage is confirmed to remain below 70V or 80V respectively.

Q: What is the difference between B1100-13-F and B1100Q-13-F?

A: B1100Q-13-F is an automotive-grade variant with AEC-Q101 qualification and extended temperature range to 155°C. Use B1100Q-13-F for automotive applications; use B1100-13-F for standard industrial applications.

Q: Why do some substitute parts have lower forward voltage (770 mV) compared to the S100 (850 mV)?

A: Lower forward voltage indicates improved efficiency and reduced power dissipation during forward conduction. Parts such as SS1H10-E3/61T, STPS1H100A, and STPS1H100AY with 770 mV forward voltage are suitable replacements and offer performance benefits in switching applications.

Q: Is the S100 compatible with the packaging of all substitute parts?

A: All substitute parts use DO-214AC (SMA) package and surface mount technology, matching the S100 footprint. However, packaging format differs: S100 is supplied in Cut Tape (CT) & Digi-Reel®, while some substitutes (B170-13-F, B180-13-F, MS110_R1_00001, SS110) are supplied in Tape & Reel (TR). Verify tape format compatibility with your assembly equipment.

Q: Can I use STPS1H100AY in place of STPS1H100A?

A: Yes. STPS1H100AY is an automotive-grade variant of STPS1H100A with identical electrical specifications and extended low-temperature operation (-40°C vs. unspecified minimum). STPS1H100AY is suitable for all applications where STPS1H100A is used, with additional automotive qualification.

Q: What is the significance of reverse leakage current differences between substitute parts?

A: Reverse leakage current affects power consumption in reverse-biased conditions. The S100 specifies 200 µA @ 100V. Substitute parts range from 1 µA (MS110_R1_00001, SS1H10-E3/61T) to 500 µA (B1100-13-F, B180-13-F, SS110, SS110-TP). Lower leakage is beneficial for low-power and precision applications; higher leakage is acceptable for general switching applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification, matching the S100 specification.

Q: Which substitute part offers the best temperature performance?

A: MS110_R1_00001, SS1H10-E3/61T, STPS1H100A, and STPS1H100AY all support operation to 175°C maximum junction temperature, compared to the S100 limit of 125°C. STPS1H100AY additionally specifies minimum operating temperature of -40°C, providing the widest specified temperature range (-40°C to 175°C).

Q: Can I use SS110-TP for new designs?

A: No. SS110-TP carries obsolete product status. Use only for legacy system support. For new designs, select from active-status alternatives such as B1100-13-F, MS110_R1_00001, SS110, SS1H10-E3/61T, STPS1H100A, or STPS1H100AY.
