HSMS-2802-TR2G Equivalent & Substitute Parts

Part Overview

The HSMS-2802-TR2G 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 mechanical package footprint.

Substitute Part Grouping Explanation

Substitution eligibility for the HSMS-2802-TR2G is determined by the following critical parameters:

Diode Configuration: Must be 1 pair series connection Schottky technology
Voltage Rating: DC reverse voltage (Vr) must be 70V minimum
Package: Must be TO-236-3, SC-59, or SOT-23-3 surface mount
Thermal Rating: Operating temperature junction must support 150°C maximum
Current Handling: Average rectified current per diode must support application requirements
Compliance: RoHS3 compliance and REACH unaffected status required

All four substitute parts meet these core substitution criteria. Differences in current ratings (70mA to 100mA per diode) and reverse leakage characteristics represent performance variations within the allowed parameter range for this product category.

Engineering Selection Recommendations

Primary Recommendation: BAS70-04LT1G (onsemi) or BAS70-04,215 (Nexperia)

Both parts are active products with ROHS3 compliance and unlimited moisture sensitivity rating. The BAS70-04LT1G offers 100mA average rectified current per diode, providing higher current capacity than the 70mA alternatives. The BAS70-04,215 is available in higher inventory volume (36,300 pcs) with Cut Tape and Digi-Reel packaging options.

Secondary Recommendation: BAS7004E6327HTSA1 or BAS7004E6433HTMA1 (Infineon)

Both Infineon variants are active products with identical electrical specifications (70mA per diode) and include reverse recovery time specification (100 ps). The BAS7004E6327HTSA1 is available in Cut Tape packaging, while the BAS7004E6433HTMA1 is supplied in Tape & Reel format. These parts are suitable for applications where the 70mA current rating is sufficient.

All substitute parts maintain the 70V reverse voltage rating, SOT-23-3 package compatibility, and 150°C maximum junction temperature of the original HSMS-2802-TR2G.

Frequently Asked Questions (FAQ)

Q: Can BAS70-04LT1G replace HSMS-2802-TR2G in all applications?

A: BAS70-04LT1G is electrically compatible within the specified parameter range. Both parts share identical 70V reverse voltage rating, SOT-23-3 package, and 150°C maximum junction temperature. The substitute part supports 100mA average rectified current per diode, which is lower than the original 1A rating. Verify that your application current requirements do not exceed 100mA per diode.

Q: What is the difference between the Nexperia and Infineon substitute options?

A: Both manufacturers provide 70V Schottky diode arrays in SOT-23-3 packages. Nexperia BAS70-04,215 offers 70mA current rating with higher inventory availability. Infineon BAS7004 variants (both 70mA) include reverse recovery time specification (100 ps) and lower reverse leakage current (100 nA @ 50V). Selection depends on current requirements and packaging preference (Cut Tape vs. Tape & Reel).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All four substitute parts carry ROHS3 Compliant status and REACH Unaffected designation, meeting current environmental and regulatory requirements.

Q: What is the impact of the current rating difference between HSMS-2802-TR2G (1A) and substitute parts (70-100mA)?

A: The substitute parts have lower average rectified current ratings. Applications requiring continuous current above 100mA per diode cannot use these substitutes. For applications operating below 100mA, the lower current rating does not affect functionality. Thermal performance and voltage ratings remain equivalent.

Q: Can I use BAS70-04,215 and BAS70-04LT1G interchangeably?

A: Both parts are pin-compatible in SOT-23-3 packages and share identical 70V voltage ratings and 150°C thermal limits. The primary difference is current rating: BAS70-04,215 supports 70mA while BAS70-04LT1G supports 100mA per diode. Selection depends on application current requirements and packaging availability.
