HSMS-2802-BLKG Equivalent & Substitute Parts

Part Overview

The HSMS-2802-BLKG is an RF Schottky diode manufactured by Broadcom Limited, configured as a 1 Pair Series Connection with a peak reverse voltage rating of 70V and maximum current of 1A in a SOT-23-3 surface mount package. This part is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain electrical compatibility across voltage, current, and thermal specifications while supporting the same package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HSMS-2802-BLKG is determined by the following critical parameters:

• Diode Configuration: Must be 1 Pair Series Connection Schottky technology
• Voltage Rating: Peak reverse voltage must be 70V (maximum)
• Package: Must be TO-236-3, SC-59, or SOT-23-3 surface mount
• Current Handling: Rated current must support the application requirements
• Operating Temperature: Maximum junction temperature of 150°C or higher
• Compliance: RoHS3 compliance and REACH unaffected status required for modern production

The substitute parts listed below meet these core electrical and mechanical criteria. Parts are grouped by manufacturer and current rating capability.

Parameter Comparison

Engineering Selection Recommendations

Direct Package-Compatible Substitutes (SOT-23-3 Configuration)

BAS70-04,215 (Nexperia), BAS70-04LT1G (onsemi), BAS7004E6327HTSA1 (Infineon), and BAS7004E6433HTMA1 (Infineon) are all 1 Pair Series Connection Schottky diodes rated at 70V in SOT-23-3 packages. All four maintain the same package footprint and diode configuration as the HSMS-2802-BLKG. These parts are active products with ROHS3 compliance and unlimited moisture sensitivity rating. Selection among these four depends on current rating requirements: BAS70-04,215 and the Infineon variants support 70mA, while BAS70-04LT1G supports 100mA. For applications requiring the full 1A rating of the original part, none of these direct substitutes provide equivalent current capacity.

Alternative Configuration (Single Diode, Different Package)

MADS-001340-12790T (MACOM) is a single Schottky diode rated at 70V with 200mA current capacity in an SC-79 package. This part differs in both diode configuration (single vs. 1 Pair Series Connection) and package type (SC-79 vs. SOT-23-3). This substitute is suitable only for applications where the circuit topology can accommodate a single diode configuration and where the SC-79 package footprint is acceptable. The maximum operating temperature is 125°C, which is 25°C lower than the original part.

Current Rating Considerations

Applications requiring the full 1A current capacity of the HSMS-2802-BLKG cannot be directly substituted with the listed parts. The highest current-rated substitute is MADS-001340-12790T at 200mA. For 1A applications, alternative Schottky diode families with higher current ratings must be evaluated.

Frequently Asked Questions (FAQ)

Q: Can BAS70-04,215 directly replace HSMS-2802-BLKG in my circuit?

A: BAS70-04,215 is electrically compatible if your application current requirement does not exceed 70mA. Both parts are 1 Pair Series Connection Schottky diodes rated at 70V in SOT-23-3 packages with identical pinout. If your circuit draws more than 70mA, this substitute is not suitable.

Q: What is the difference between the Infineon BAS7004E6327HTSA1 and BAS7004E6433HTMA1?

A: Both parts are electrically identical 70V, 70mA Schottky diode arrays in SOT-23-3 packages. The difference is packaging format: BAS7004E6327HTSA1 is supplied in Cut Tape (CT) & Digi-Reel format, while BAS7004E6433HTMA1 is supplied in Tape & Reel (TR) format. Select based on your procurement and assembly requirements.

Q: Why is MADS-001340-12790T listed as a substitute if it has a different package?

A: MADS-001340-12790T meets the core electrical requirements (70V Schottky diode) but uses an SC-79 package instead of SOT-23-3. This part is listed as an alternative only for designs where package footprint flexibility exists or where the circuit topology can be modified to accommodate a single diode configuration instead of a paired configuration.

Q: Can I use BAS70-04LT1G if my application requires 1A?

A: No. BAS70-04LT1G is rated for 100mA maximum current. Using it in a 1A application will cause device failure. For 1A requirements, alternative Schottky diode families with higher current ratings must be selected.

Q: Are all substitute parts RoHS3 compliant?

A: BAS70-04,215, BAS70-04LT1G, BAS7004E6327HTSA1, and BAS7004E6433HTMA1 are all ROHS3 compliant. MADS-001340-12790T compliance status is not specified in the provided data.

Q: What is the operating temperature difference between the main part and substitutes?

A: HSMS-2802-BLKG, BAS70-04,215, BAS70-04LT1G, and the Infineon variants all support 150°C maximum junction temperature. MADS-001340-12790T supports 125°C maximum, which is 25°C lower. For high-temperature applications, use parts rated to 150°C.
