HSMS-286C-BLKG RF Schottky Diode Equivalent & Substitute Parts

Part Overview

The HSMS-286C-BLKG is an RF Schottky diode manufactured by Broadcom Limited, configured as a 1-pair series connection device rated for 4V peak reverse voltage in an SC-70/SOT-323 package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The device is suitable for RF applications requiring low-barrier Schottky diode characteristics with minimal capacitance.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the HSMS-286C-BLKG is determined by the following critical parameters:

• Diode Type: Must be Schottky - 1 Pair Series Connection
• Package: SC-70/SOT-323 form factor or compatible equivalent
• Voltage Rating: Peak reverse voltage of 4V or higher
• Capacitance: Typically 0.25pF to 0.35pF @ 0V, 1MHz for RF performance
• Operating Temperature: Support for 150°C junction temperature or equivalent thermal rating
• Moisture Sensitivity: MSL 1 (Unlimited) classification

Three substitute parts meet these criteria with varying electrical characteristics and product status classifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: BAT1504WH6327XTSA1 (Infineon Technologies)

The BAT1504WH6327XTSA1 provides the closest electrical match to the HSMS-286C-BLKG with identical 4V peak reverse voltage rating and 150°C junction temperature capability. This part maintains SC-70/SOT-323 package compatibility and is classified as active product status, ensuring long-term availability. RoHS3 compliance and REACH unaffected status support regulatory requirements. The 0.35pF capacitance is within acceptable RF performance parameters.

Secondary Substitute: MA4E2054B1-1146T (MACOM Technology Solutions)

The MA4E2054B1-1146T is an active product offering SC-70/SOT-323 package compatibility with 0.3pF capacitance suitable for RF applications. The 3V peak reverse voltage rating is lower than the original specification; this part is suitable only for applications where the 4V rating is not a critical design constraint. Active product status ensures procurement availability.

Tertiary Substitute: SBX201C-TB-E (onsemi)

The SBX201C-TB-E is classified as obsolete and features a 2V peak reverse voltage rating, making it unsuitable for direct substitution in applications requiring the full 4V rating. Package compatibility is limited to TO-236-3/SC-59/SOT-23-3 variants, requiring potential PCB layout modifications. This part should be considered only when voltage and package constraints permit.

Frequently Asked Questions (FAQ)

Q: Can MA4E2054B1-1146T replace HSMS-286C-BLKG in all applications?

A: No. The MA4E2054B1-1146T has a 3V peak reverse voltage rating compared to the original 4V specification. Substitution is valid only for circuits where the lower voltage rating does not compromise performance or reliability margins.

Q: What is the primary advantage of BAT1504WH6327XTSA1 as a substitute?

A: The BAT1504WH6327XTSA1 maintains identical voltage rating (4V), operating temperature (150°C TJ), and package form factor (SC-70/SOT-323) as the original part. Active product status ensures long-term availability and supply chain continuity.

Q: Are package modifications required when using SBX201C-TB-E?

A: Yes. The SBX201C-TB-E uses TO-236-3/SC-59/SOT-23-3 packages, which differ from the SC-70/SOT-323 form factor of the original part. PCB layout and footprint modifications are necessary.

Q: What does MSL 1 (Unlimited) mean for these components?

A: MSL 1 (Unlimited) indicates the lowest moisture sensitivity level, meaning these components can be stored indefinitely without moisture bake-out requirements prior to soldering.

Q: Are all substitute parts RoHS compliant?

A: BAT1504WH6327XTSA1 and SBX201C-TB-E are RoHS3 compliant. MA4E2054B1-1146T compliance status is not specified in the provided data.

Q: Which substitute offers the highest current handling capability?

A: BAT1504WH6327XTSA1 supports 110 mA maximum current, compared to 20 mA for MA4E2054B1-1146T and 50 mA for SBX201C-TB-E.
