Key Parameters

Substitute Part Grouping Explanation

Substitution of the HSMP-3813-TR2G is determined by the following critical parameters:

• Diode Type: PIN - 1 Pair Common Anode configuration must be maintained for circuit compatibility
• Package / Case: SOT-23-3 (TO-236-3, SC-59) physical form factor ensures PCB layout compatibility
• Voltage - Peak Reverse (Max): Substitute must meet or exceed 100V rating
• Current - Max: Substitute must support minimum 1A operation
• Resistance @ If, F: Forward resistance at specified bias conditions must be compatible with circuit design
• Capacitance @ Vr, F: Junction capacitance characteristics affect RF performance and switching speed

The SMP1307-003LF from Skyworks Solutions Inc. meets all substitution criteria through equivalent package configuration, matching diode topology, and electrical parameter compatibility within acceptable design margins.

Engineering Selection Recommendations

The SMP1307-003LF is the recommended substitute for the obsolete HSMP-3813-TR2G based on the following factors:

• Product Status: The SMP1307-003LF maintains active manufacturing status, ensuring long-term availability and supply chain continuity
• Compliance: The SMP1307-003LF is ROHS3 compliant, meeting current regulatory requirements for new designs and manufacturing
• Electrical Compatibility: Forward resistance, capacitance characteristics, and package configuration provide direct functional equivalence
• Voltage Margin: The 200V peak reverse voltage rating of the SMP1307-003LF exceeds the 100V requirement of the original part, providing additional design margin
• Thermal Performance: Extended operating temperature range (-65°C ~ 150°C) supports broader application environments

Frequently Asked Questions (FAQ)

Q: Can the SMP1307-003LF be used as a direct replacement for the HSMP-3813-TR2G in existing designs?

A: Yes. Both components share identical SOT-23-3 package configuration, PIN diode topology with common anode configuration, and matching forward resistance characteristics at specified bias conditions. Pin-for-pin compatibility is maintained.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Peak reverse voltage rating—SMP1307-003LF is rated for 200V versus 100V for the HSMP-3813-TR2G; (2) Product status—SMP1307-003LF is actively manufactured while HSMP-3813-TR2G is obsolete; (3) Compliance—SMP1307-003LF is ROHS3 compliant; (4) Operating temperature range—SMP1307-003LF specifies -65°C ~ 150°C versus 150°C maximum for the original part.

Q: Are there any circuit design considerations when substituting these parts?

A: The higher voltage rating of the SMP1307-003LF does not negatively impact circuit performance in applications designed for 100V operation. The matching forward resistance (3Ohm @ 100mA, 100MHz) and comparable capacitance characteristics ensure RF switching and attenuation performance remain consistent with original design specifications.

Q: What is the moisture sensitivity level for both parts?

A: Both the HSMP-3813-TR2G and SMP1307-003LF are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Is the SMP1307-003LF available in the same packaging format?

A: Yes. The SMP1307-003LF is supplied in Tape & Reel (TR) format in SOT-23-3 package configuration, matching the original part's physical specifications for automated assembly processes.
