HSMS-2820-TR2G Equivalent & Substitute Parts

Part Overview

The HSMS-2820-TR2G is an RF Schottky diode manufactured by Broadcom Limited, designed for single-diode applications requiring peak reverse voltage handling up to 15V with 1A maximum current capability. The device is packaged in SOT-23-3 (TO-236-3, SC-59) configuration. This part is classified as obsolete, necessitating identification of active substitute components that maintain functional compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HSMS-2820-TR2G requires strict adherence to the following electrical and mechanical criteria:

Mandatory Compatibility Parameters:

• Package type: SOT-23-3 (TO-236-3, SC-59) — mechanical and pin compatibility
• Diode type: Schottky - Single — functional topology
• Operating temperature range: 150°C (TJ) minimum
• Voltage - Peak Reverse (Max): Must equal or exceed 15V
• Current - Max: Must equal or exceed 1 A

The SMS3922-001LF is identified as a manufacturer-recommended substitute. However, this part exhibits reduced electrical ratings: peak reverse voltage of 8V (versus 15V required) and maximum current of 50 mA (versus 1 A required). These reductions indicate the SMS3922-001LF is suitable only for applications where the circuit design operates within the lower electrical envelope of the substitute part.

Parameter Comparison

Engineering Selection Recommendations

The HSMS-2820-TR2G is obsolete; active component sourcing requires evaluation of substitute options based on application requirements.

SMS3922-001LF Selection Criteria:

• Product status: Active with 9541 units in stock
• RoHS3 compliance confirmed
• Identical package (SOT-23-3) and MSL rating (1 - Unlimited)
• Identical operating temperature maximum (150°C TJ)
• Suitable for applications where circuit design operates within 8V peak reverse voltage and 50 mA maximum current specifications

Application Scope: The SMS3922-001LF substitution is valid only when the original circuit design does not require the full 15V reverse voltage or 1A current capability of the HSMS-2820-TR2G. If the application demands these higher electrical ratings, alternative Schottky diodes with matching or superior specifications must be evaluated.

Frequently Asked Questions (FAQ)

Q: Can SMS3922-001LF directly replace HSMS-2820-TR2G in all applications?

A: No. The SMS3922-001LF has reduced electrical ratings (8V peak reverse voltage versus 15V; 50 mA maximum current versus 1 A). Substitution is valid only if the circuit design operates within these lower specifications.

Q: Are the packages mechanically compatible?

A: Yes. Both parts use SOT-23-3 (TO-236-3, SC-59) packaging, ensuring pin-for-pin mechanical compatibility and identical PCB footprints.

Q: What is the moisture sensitivity difference?

A: Both parts have MSL rating 1 (Unlimited), indicating identical moisture handling requirements and storage conditions.

Q: Why is HSMS-2820-TR2G obsolete?

A: Product status is determined by manufacturer lifecycle decisions. Active alternatives with equivalent or superior specifications should be evaluated for new designs or component replacement.

Q: Are there compliance differences between the parts?

A: SMS3922-001LF is RoHS3 compliant. Both parts are REACH Unaffected and classified under EAR99 export control.
