HSMS-282P-TR1G Equivalent & Substitute Parts

Part Overview

The HSMS-282P-TR1G is an RF Schottky diode manufactured by Broadcom Limited, configured as a 2-pair series connection device rated for 15V peak reverse voltage and 1A maximum current in a 6-TSSOP (SOT-363) 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 across RF applications while accommodating the electrical and mechanical constraints of the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HSMS-282P-TR1G requires evaluation based on the following critical parameters:

• Diode Type & Configuration: Schottky diode technology with RF-grade performance characteristics
• Voltage Rating: Peak reverse voltage capability of 15V or greater
• Current Handling: Maximum current rating of 1A or greater
• Capacitance Characteristics: Low junction capacitance (1pF @ 0V, 1MHz) for RF signal integrity
• Series Resistance: Forward resistance of 12Ohm @ 5mA, 1MHz or lower for minimal signal loss
• Package Compatibility: Physical and electrical compatibility with SOT-363 footprint requirements
• Operating Temperature Range: Minimum junction temperature rating of 150°C
• Product Status & Availability: Active production status preferred for long-term supply assurance

The identified substitute MADS-001338-12790T from MACOM Technology Solutions is classified as manufacturer-recommended and carries active product status. However, direct parameter comparison reveals significant deviations in voltage rating, current capacity, and package form factor that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The MADS-001338-12790T is designated as manufacturer-recommended by MACOM and maintains active production status, providing supply chain advantages over the obsolete HSMS-282P-TR1G. However, direct electrical substitution is not feasible based on provided specifications.

Voltage Rating Limitation: The MACOM part is rated for 8V maximum peak reverse voltage, which is 7V below the Broadcom specification. Applications requiring the full 15V rating cannot use this substitute without circuit redesign or voltage derating.

Current Rating Limitation: The MACOM part is rated for 30mA maximum current, representing a 97% reduction from the 1A specification of the Broadcom part. This substitute is suitable only for low-current RF signal applications and cannot support the original 1A current requirement.

Operating Temperature Limitation: The MACOM part maximum junction temperature is 125°C, which is 25°C below the Broadcom specification of 150°C. Applications operating at elevated temperatures may exceed the MACOM device's thermal limits.

Package Incompatibility: The MACOM part uses SC-79 or SOD-523 packaging, which differs from the SOT-363 footprint of the original part. PCB layout modifications are required for physical implementation.

Compliance & Certifications: The MACOM part is specified as lead-free, meeting RoHS compliance requirements. The Broadcom part carries REACH Unaffected status and EAR99 export classification.

Selection of the MADS-001338-12790T should be limited to applications where voltage, current, and temperature requirements are substantially lower than the original specification, and where package redesign is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the MADS-001338-12790T directly replace the HSMS-282P-TR1G in existing designs?

A: No. The MACOM part has significantly lower voltage (8V vs. 15V), current (30mA vs. 1A), and temperature (125°C vs. 150°C) ratings. Direct substitution is not electrically compatible. PCB redesign is also required due to different package footprints (SC-79/SOD-523 vs. SOT-363).

Q: What applications are suitable for the MADS-001338-12790T substitute?

A: The MACOM part is suitable for low-voltage, low-current RF signal applications where peak reverse voltage does not exceed 8V, forward current does not exceed 30mA, and operating temperature remains below 125°C. Typical applications include small-signal RF switching and detection circuits.

Q: Are there other substitute options available for the HSMS-282P-TR1G?

A: The provided substitute list contains only the MADS-001338-12790T. Additional alternatives may exist from other manufacturers, but they are not included in this reference.

Q: What is the significance of the SOT-363 package for the original part?

A: The SOT-363 (6-TSSOP) package is a surface-mount form factor with specific pin spacing and height constraints. Any substitute must either use the same package or require PCB redesign to accommodate alternative packages such as SC-79 or SOD-523.

Q: Does the lead-free specification of the MACOM part affect compatibility?

A: Lead-free components use different solder alloys and may have different thermal characteristics. If the original design used lead-based solder processes, transition to lead-free components requires validation of solder joint reliability and thermal performance.

Q: What does "Schottky - 2 Pair Series Connection" mean for the Broadcom part?

A: This indicates the HSMS-282P-TR1G contains two pairs of Schottky diodes connected in series within a single package. The MACOM substitute is a single Schottky diode, representing a different internal configuration and electrical behavior.
