HSMS-282C-TR1G Equivalent & Substitute Parts

Part Overview

The HSMS-282C-TR1G is an RF Schottky diode manufactured by Broadcom Limited, configured as a 1 pair series connection with a peak reverse voltage rating of 15V and maximum current of 1A in an SC-70 SOT-323 surface mount package. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. Substitute parts must maintain compatibility with the original electrical specifications and physical package requirements while meeting current availability and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HSMS-282C-TR1G is determined by the following critical parameters:

Package Compatibility: All substitute parts must use the SC-70 SOT-323 surface mount package to ensure mechanical and electrical compatibility with existing PCB layouts.

Diode Configuration: Substitutes must maintain the 1 pair series connection topology to preserve circuit functionality.

Voltage Rating: The peak reverse voltage must meet or exceed 15V to ensure the substitute operates safely within the original design envelope.

Current Handling: The maximum current rating must support the application requirements. Substitutes with lower current ratings (30mA) are acceptable only in applications where current demand does not exceed the substitute's specification.

Thermal Performance: Operating temperature range must accommodate the application's thermal environment. The original part specifies 150°C maximum junction temperature.

Electrical Characteristics: Capacitance and resistance parameters should align with the original specifications to maintain circuit performance, though minor variations are acceptable within typical engineering tolerances.

Parameter Comparison

Engineering Selection Recommendations

MA4E1338B1-1146T (MACOM): This substitute maintains identical capacitance characteristics (1pF @ 0V, 1MHz) and package compatibility. However, the 8V peak reverse voltage rating is below the original 15V specification, and the 30mA current limit represents a significant reduction from the 1A rating. This substitute is suitable only for low-power applications where circuit voltage and current demands do not approach the original specifications. The part is currently active in production.

1PS70SB84,115 (Nexperia): This substitute matches the 15V peak reverse voltage rating and maintains SC-70 SOT-323 package compatibility. The 30mA current specification is lower than the original 1A rating. This part carries automotive-grade qualification (AEC-Q100) and ROHS3 compliance, making it suitable for applications requiring regulatory compliance. The part is currently active in production.

BAT54SWFILM (STMicroelectronics): This substitute exceeds the original specifications with a 40V peak reverse voltage rating and 300mA current capacity, providing design margin for higher-stress applications. It maintains SC-70 SOT-323 package compatibility and operates across the full temperature range (-40°C to 150°C) matching the original maximum junction temperature. ROHS3 compliance is provided. The part is currently active in production.

Selection should prioritize active, currently manufactured parts to ensure long-term supply chain stability. Voltage and current ratings must align with application requirements; oversized ratings provide design margin but may introduce unnecessary cost.

Frequently Asked Questions (FAQ)

Q: Can MA4E1338B1-1146T replace HSMS-282C-TR1G in all applications?

A: No. The MA4E1338B1-1146T has an 8V peak reverse voltage rating, which is below the original 15V specification. It is suitable only for applications where the circuit voltage does not exceed 8V. The 30mA current limit also restricts use to low-power circuits.

Q: What is the primary limitation of using 1PS70SB84,115 as a substitute?

A: The 1PS70SB84,115 has a maximum current rating of 30mA, compared to the original 1A specification. Applications requiring higher current handling must use BAT54SWFILM or verify that circuit current demands remain below 30mA.

Q: Why does BAT54SWFILM have higher voltage and current ratings than the original part?

A: BAT54SWFILM is designed for higher-stress applications. The elevated ratings (40V, 300mA) provide design margin and are backward compatible with the original 15V, 1A application envelope. Higher ratings do not prevent use in lower-stress circuits.

Q: Are all substitute parts available in the same package?

A: Yes. All substitute parts use the SC-70 SOT-323 surface mount package, ensuring mechanical compatibility with existing PCB layouts without requiring design modifications.

Q: Which substitute part has the best compliance certifications?

A: 1PS70SB84,115 carries automotive-grade qualification (AEC-Q100) and ROHS3 compliance. BAT54SWFILM provides ROHS3 compliance. Applications requiring automotive or regulatory compliance should prioritize these parts.

Q: Can I use BAT54SWFILM as a direct replacement without circuit modifications?

A: Yes. BAT54SWFILM maintains SC-70 SOT-323 package compatibility and operates within the original temperature range. The higher voltage and current ratings are backward compatible with the original 15V, 1A specification.

Q: What is the moisture sensitivity level for all substitute parts?

A: All substitute parts, including the original HSMS-282C-TR1G, have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
