SSA210 Equivalent & Substitute Parts

Part Overview

The SSA210 is a Schottky rectifier diode manufactured by onsemi, rated for 100 V DC reverse voltage and 2 A average rectified current in a surface mount DO-214AC (SMA) package. This component is classified as "Not For New Designs," indicating it has reached end-of-life status. Identifying equivalent and substitute parts is necessary for ongoing maintenance, repair, and legacy system support where the original part is no longer available or procurement is limited.

Substitute Part Grouping Explanation

Substitution of the SSA210 is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 100 V
Current - Average Rectified (Io): 2 A
Package / Case: DO-214AC, SMA
Mounting Type: Surface Mount
Technology: Schottky
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Secondary Compatibility Factors:

Operating Temperature - Junction range must encompass or exceed the application requirements
Forward voltage (Vf) must not exceed 800 mV @ 2 A to maintain circuit performance
Reverse leakage current must remain within acceptable limits for the application
RoHS3 compliance and MSL rating must match or exceed the original specification

Parts are grouped into two categories:

Direct Equivalents (2 A rated): Parts meeting all primary criteria with identical or superior electrical characteristics and current rating.

Parametric Equivalents (1 A rated): Parts with reduced current rating (1 A vs. 2 A) that may be used only in applications where the actual circuit current demand does not exceed 1 A.

Parametric Equivalents (1 A Rated, Limited Substitution):

The following parts have reduced current rating (1 A vs. 2 A) and are suitable only for applications where actual circuit current does not exceed 1 A:

B1100-13-F (Diodes Incorporated): Active product with 1 A rating. Forward voltage 790 mV @ 1 A. Operating temperature range -65°C to 150°C. Available in Cut Tape and Digi-Reel® packaging.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating. Parts designated with AEC-Q101 qualification (B1100Q-13-F, SS210A, VSSA210HM3_A/H, BR210-AU_R1_000A1) are suitable for automotive applications. Selection should account for application-specific temperature requirements and current demands.

Frequently Asked Questions (FAQ)

Q: Can I use a 1 A rated diode (B1100-13-F or B1100Q-13-F) as a direct replacement for the SSA210?

A: No, not as a direct replacement. The SSA210 is rated for 2 A average rectified current. The B1100 series parts are rated for 1 A. These parts may be used only if the actual circuit current demand does not exceed 1 A. Using a 1 A part in a 2 A circuit will result in component failure.

Q: What is the difference between the two Panjit parts (BR210_R1_00001 and BR210-AU_R1_000A1)?

A: Both parts have identical electrical characteristics (100 V, 2 A, 800 mV Vf, 50 µA reverse leakage). The primary difference is that BR210-AU_R1_000A1 includes AEC-Q101 automotive qualification and extends the upper operating temperature to 175°C, compared to 150°C for BR210_R1_00001. Select BR210-AU_R1_000A1 for automotive applications or systems requiring extended temperature operation.

Q: Why does VSSA210HM3_A/H have a lower forward voltage (700 mV) than the SSA210 (800 mV)?

A: Lower forward voltage is a characteristic of the Vishay TMBS® series technology. This represents an improvement in efficiency and reduced power dissipation. The part remains functionally equivalent and is suitable for direct replacement. The lower Vf may improve circuit performance.

Q: Are all substitute parts available in the same packaging as the SSA210?

A: The SSA210 is supplied in Tape & Reel (TR) packaging. Most substitute parts are available in either Tape & Reel or Cut Tape with Digi-Reel® packaging. Verify packaging availability with your supplier before ordering. Package selection does not affect electrical performance.

Q: What is the significance of the extended temperature range in MBRA2H100T3G (-65°C to 175°C)?

A: The extended lower temperature limit (-65°C vs. -55°C) and upper limit (175°C vs. 150°C) provides greater operational flexibility for applications exposed to extreme environmental conditions. If your application operates within the SSA210 range (-55°C to 175°C), MBRA2H100T3G provides full compatibility with additional margin at the lower temperature extreme.

Q: Can I substitute the SSA210 with SS210A from HY Electronic?

A: Yes, with consideration. SS210A meets all primary electrical criteria (100 V, 2 A, DO-214AC package). However, the forward voltage is 850 mV @ 2 A, which exceeds the SSA210 specification of 800 mV. This 50 mV difference may impact circuit performance in voltage-sensitive applications. Additionally, the upper operating temperature is limited to 150°C compared to 175°C for the SSA210. Verify circuit tolerance before selection.

Q: Which substitute part offers the best overall performance improvement?

A: VSSA210HM3_A/H from Vishay offers the lowest forward voltage (700 mV @ 2 A), resulting in reduced power dissipation and improved efficiency. It includes AEC-Q101 automotive qualification. However, the upper operating temperature is limited to 150°C. For applications requiring the full -55°C to 175°C range with automotive qualification, BR210-AU_R1_000A1 is the optimal choice.

Q: What does "Not For New Designs" mean for the SSA210?

A: This designation indicates the SSA210 has reached end-of-life status and onsemi no longer recommends it for new circuit designs. Existing inventory may be available, but long-term supply is not guaranteed. For new designs and ongoing production, select an active substitute part such as MBRA2H100T3G, BR210_R1_00001, or VSSA210HM3_A/H.

Q: Are there any reverse leakage current differences I should consider?

A: Yes. The SSA210 specifies 50 µA @ 100 V reverse leakage. MBRA2H100T3G offers superior performance at 8 µA. SS210A has higher leakage at 1 mA, which may be significant in high-impedance circuits. VSSA210HM3_A/H specifies 150 µA. For applications sensitive to reverse leakage, MBRA2H100T3G is the preferred choice.
