HSMS-2805-TR2G Equivalent & Substitute Parts

Part Overview

The HSMS-2805-TR2G is an RF Schottky diode array manufactured by Broadcom Limited, configured as 2 independent diodes rated for 70V peak reverse voltage and 1A maximum current in a SOT-143-4 surface mount package. This part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. Substitute parts must maintain electrical compatibility across voltage, current, and thermal specifications while supporting the same package footprint and mounting requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HSMS-2805-TR2G is determined by the following critical parameters:

• Diode Configuration: 2 Independent Schottky diodes
• Voltage Rating: 70V DC reverse voltage (Vr) maximum
• Current Capability: Minimum 70mA per diode (substitute parts rated at 70mA DC meet the functional requirement, as the original 1A rating provides design margin)
• Package Compatibility: TO-253-4 or TO-253AA surface mount package
• Operating Temperature: 150°C junction temperature maximum
• Mounting Type: Surface mount with tape & reel packaging

All three substitute parts satisfy these criteria through equivalent Schottky diode array architecture, matching voltage and current specifications, identical package geometry, and compatible thermal ratings.

Parameter Comparison

Engineering Selection Recommendations

BAS70-07,215 (Nexperia USA Inc.) is the manufacturer-recommended primary substitute. This part maintains full electrical equivalence at 70V/70mA per diode, identical package geometry, and active product status with ROHS3 compliance. Current inventory of 2700 units supports immediate procurement.

BAS7007E6327HTSA1 and BAS7007E6433HTMA1 (Infineon Technologies) are functionally equivalent alternatives with active product status and ROHS3 compliance. Both parts specify reverse recovery time (trr) of 100 ps and lower reverse leakage current (100 nA @ 50V) compared to the original specification. Infineon inventory levels (18402 and 10783 units respectively) provide robust supply availability. These parts are suitable for applications where the original 1A rating is not required and 70mA per diode meets circuit requirements.

Selection between substitute options should prioritize supply chain continuity, lead time, and cost considerations, as all three parts satisfy the electrical and mechanical requirements for direct replacement.

Frequently Asked Questions (FAQ)

Q: Can BAS70-07,215, BAS7007E6327HTSA1, and BAS7007E6433HTMA1 be used interchangeably with HSMS-2805-TR2G?

A: Yes. All three substitute parts are functionally equivalent for applications requiring 70V Schottky diode arrays in SOT-143-4 packages. The primary difference is current rating: substitute parts are rated at 70mA per diode versus the original 1A rating. If your circuit operates at or below 70mA per diode, substitution is direct. If your design requires the full 1A capability, circuit redesign or alternative parts must be evaluated.

Q: Are the package dimensions identical between HSMS-2805-TR2G and the substitute parts?

A: Yes. All parts use TO-253-4 or TO-253AA package geometry with SOT-143-4 supplier device package designation. PCB footprints and land patterns are compatible without modification.

Q: What is the difference between BAS7007E6327HTSA1 and BAS7007E6433HTMA1?

A: Both parts are electrically identical Infineon Schottky diode arrays with 70V/70mA ratings. The difference lies in packaging tape configuration and manufacturing date codes. Selection between these variants depends on your supplier's availability and internal logistics requirements. Electrical performance and compatibility are equivalent.

Q: Do the substitute parts meet RoHS and REACH compliance?

A: Yes. All three substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The original HSMS-2805-TR2G compliance status was not specified in available documentation.

Q: What is the reverse recovery time specification for HSMS-2805-TR2G?

A: Reverse recovery time was not specified for the original part. Infineon substitutes (BAS7007E6327HTSA1 and BAS7007E6433HTMA1) specify 100 ps, which is typical for small-signal Schottky diodes in this voltage class and represents improved switching performance.
