HSMS-2805-TR1G Equivalent & Substitute Parts

Part Overview

The HSMS-2805-TR1G 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 active equivalent components essential for new designs and production continuity. Substitute parts must maintain electrical compatibility across voltage ratings, current handling, and package form factor while offering active product status from current manufacturers.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Compatibility Parameters:

  • Diode configuration: 2 Independent Schottky diodes
  • Voltage rating: 70V DC reverse voltage (Vr) maximum
  • Package form factor: TO-253-4 / TO-253AA / SOT-143 variants
  • Operating temperature range: 150°C junction temperature capability
  • Mounting type: Surface mount

Secondary Compatibility Parameters:

  • Current handling: Minimum 70mA per diode (HSMS-2805 rated 1A; substitutes rated 70mA minimum meet reduced-current applications)
  • Forward voltage: Maximum 1V @ 15mA
  • Reverse leakage: Specified at rated voltage

Substitute parts are grouped into two categories based on configuration match:

Category A - Direct Array Equivalents (2 Independent Diodes):

  • BAS70-07,215 (Nexperia)
  • BAS7007E6327HTSA1 (Infineon)
  • BAS7007E6433HTMA1 (Infineon)

Category B - Single Diode Alternative:

  • MADS-001340-12790T (MACOM) - Single diode configuration; requires dual-diode implementation for functional equivalence

Engineering Selection Recommendations

For Direct Replacement (2 Independent Diode Configuration):

BAS70-07,215, BAS7007E6327HTSA1, and BAS7007E6433HTMA1 are functionally equivalent substitutes. All three maintain 70V reverse voltage rating, 2-diode independent configuration, and TO-253-4 / SOT-143 package compatibility. Selection among these three is determined by:

  • Availability and lead time: BAS7007E6327HTSA1 (18,402 units in stock) and BAS7007E6433HTMA1 (10,783 units in stock) offer higher inventory levels than BAS70-07,215 (2,700 units).
  • Compliance requirements: All three are ROHS3 compliant and REACH unaffected, meeting current regulatory standards.
  • Reverse leakage performance: BAS7007E6327HTSA1 and BAS7007E6433HTMA1 specify 100 nA @ 50V leakage, superior to BAS70-07,215 at 10 µA @ 70V.
  • Current derating: All three are rated 70mA per diode, suitable for applications where the HSMS-2805-TR1G's 1A rating is not fully utilized.

For Single Diode Applications:

MADS-001340-12790T (MACOM) is a single Schottky diode with 70V rating and 200mA current capacity. This part is not a direct substitute for the 2-diode array configuration but may be used in applications requiring only one diode function. Package form factor differs (SC-79 vs. SOT-143), requiring circuit board layout modification. Operating temperature maximum is 125°C, lower than the HSMS-2805-TR1G specification of 150°C.

Frequently Asked Questions (FAQ)

Q: Can BAS70-07,215, BAS7007E6327HTSA1, or BAS7007E6433HTMA1 be used as direct replacements for HSMS-2805-TR1G?

A: Yes, all three are direct substitutes. They maintain the 2-independent-diode configuration, 70V reverse voltage rating, and TO-253-4 / SOT-143 package compatibility. The primary difference is current rating: substitutes are rated 70mA per diode versus the original 1A. For applications operating below 70mA per diode, these substitutes are fully compatible.

Q: What is the difference between BAS7007E6327HTSA1 and BAS7007E6433HTMA1?

A: Both parts are manufactured by Infineon Technologies with identical electrical specifications: 70V reverse voltage, 70mA current rating, 1V forward voltage @ 15mA, and 100 nA reverse leakage @ 50V. The difference lies in packaging and tape configuration (indicated by the suffix codes E6327HTSA1 vs. E6433HTMA1). Electrical performance and pin configuration are equivalent.

Q: Why is MADS-001340-12790T not recommended as a direct replacement?

A: MADS-001340-12790T is a single Schottky diode, not a 2-diode array. The HSMS-2805-TR1G contains two independent diodes in one package. Using MADS-001340-12790T requires either dual-diode implementation (two separate components) or circuit redesign. Additionally, the SC-79 package differs from SOT-143, requiring PCB layout changes. Operating temperature is limited to 125°C versus 150°C for the original part.

Q: Are all substitute parts RoHS compliant?

A: BAS70-07,215, BAS7007E6327HTSA1, and BAS7007E6433HTMA1 are ROHS3 compliant. MADS-001340-12790T RoHS status is not specified in the provided data. Verify compliance requirements with your procurement or quality assurance department before final selection.

Q: What is the moisture sensitivity level for these parts?

A: All substitute parts (BAS70-07,215, BAS7007E6327HTSA1, BAS7007E6433HTMA1) are rated MSL 1 (Unlimited), matching the original HSMS-2805-TR1G. This indicates no moisture sensitivity restrictions for storage or handling.

Q: Can I use these substitutes in high-temperature applications?

A: BAS70-07,215, BAS7007E6327HTSA1, and BAS7007E6433HTMA1 are rated to 150°C junction temperature, matching the HSMS-2805-TR1G. MADS-001340-12790T is limited to 125°C, making it unsuitable for applications requiring 150°C operation.
