HSMS-2810-TR1G Equivalent & Substitute Parts

Part Overview

The HSMS-2810-TR1G is an RF Schottky diode manufactured by Broadcom Limited, designed for high-frequency applications requiring low capacitance and fast switching characteristics. This single Schottky diode operates at a peak reverse voltage of 20V with a maximum current rating of 1A in a compact SOT-23-3 surface mount package. The part is currently classified as obsolete, making equivalent substitutes necessary for ongoing design support and production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HSMS-2810-TR1G is determined by the following critical parameters:

• Voltage Rating: All substitutes must maintain a peak reverse voltage of 20V to ensure safe operation in the same circuit topology
• Package Compatibility: All substitutes use the TO-236-3/SOT-23-3 package, ensuring mechanical and electrical pin compatibility
• Diode Technology: All substitutes are Schottky diodes, maintaining the same switching speed and forward voltage characteristics required for RF applications
• Capacitance Characteristics: Substitutes maintain capacitance values in the 1.2pF to 80pF range at specified bias voltages, suitable for RF frequency applications
• Current Rating: Substitutes range from 30mA to 1A, with higher current ratings providing backward compatibility

The substitute parts are grouped into two categories: direct electrical equivalents (MA4E1339A1-287T) and higher-current rated alternatives (PMEG2005ET,215, PMEG2010AET,215, PMEG2010ET,215) that maintain the same voltage and package specifications.

Parameter Comparison

Engineering Selection Recommendations

MA4E1339A1-287T is the closest electrical equivalent to the HSMS-2810-TR1G, matching the capacitance specification of 1.2pF at 0V, 1MHz. However, this substitute has a reduced maximum current rating of 30mA compared to the original 1A specification. This part is suitable only for applications where the circuit current does not exceed 30mA.

PMEG2005ET,215 provides a 500mA current rating with a 20V voltage specification and maintains the same SOT-23-3 package. This part is ROHS3 compliant and active in production, making it suitable for applications requiring moderate current levels up to 500mA.

PMEG2010AET,215 and PMEG2010ET,215 both provide full 1A current rating matching the original HSMS-2810-TR1G specification. Both parts are ROHS3 compliant, carry AEC-Q100 automotive qualification, and are active in production. The primary difference between these two Nexperia parts is the forward voltage specification: PMEG2010AET,215 specifies 430mV @ 1A, while PMEG2010ET,215 specifies 500mV @ 1A. Both maintain the 20V peak reverse voltage and SOT-23-3 package compatibility.

For applications requiring full 1A current capacity with modern compliance certifications, PMEG2010AET,215 is the preferred substitute due to its lower forward voltage specification and automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can MA4E1339A1-287T be used as a direct replacement for HSMS-2810-TR1G?

A: MA4E1339A1-287T is electrically compatible in terms of voltage rating, package, and capacitance characteristics. However, its maximum current rating of 30mA is significantly lower than the original 1A specification. Use this substitute only if your circuit current does not exceed 30mA.

Q: What is the difference between PMEG2010AET,215 and PMEG2010ET,215?

A: Both parts share identical voltage ratings (20V), current ratings (1A), package specifications (SOT-23-3), and operating temperature ranges (150°C max). The primary difference is forward voltage: PMEG2010AET,215 specifies 430mV @ 1A, while PMEG2010ET,215 specifies 500mV @ 1A. Both are AEC-Q100 qualified and ROHS3 compliant.

Q: Are all substitute parts available in the same package as the original HSMS-2810-TR1G?

A: Yes. All substitute parts use the TO-236-3/SC-59/SOT-23-3 package, ensuring direct mechanical and electrical compatibility with existing PCB layouts.

Q: Which substitute part should I select for a new design?

A: For applications requiring the full 1A current rating with modern compliance requirements, select either PMEG2010AET,215 or PMEG2010ET,215. Both are active in production, ROHS3 compliant, and AEC-Q100 qualified. For applications with current requirements between 500mA and 1A, PMEG2005ET,215 is a suitable alternative.

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

A: All substitute parts maintain MSL 1 (Unlimited), matching the original HSMS-2810-TR1G specification. This indicates no moisture sensitivity restrictions during storage or handling.
