HSCH-5310 Equivalent & Substitute Parts

Part Overview

The HSCH-5310 is an RF Schottky diode manufactured by Broadcom Limited, designed for high-frequency applications requiring low capacitance and fast switching characteristics. This component features a peak reverse voltage rating of 4V and maximum power dissipation of 150 mW in a 2-SMD flat lead package. The product is currently obsolete, making equivalent substitutes necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HSCH-5310 is determined by the following critical parameters:

• Diode Type: Must be Schottky - Single configuration
• Package Compatibility: 2-SMD flat lead package required for mechanical and electrical interface compatibility
• Voltage Rating: Peak reverse voltage must meet or exceed 4V application requirements
• Power Dissipation: Thermal capability must support 150 mW or higher
• Capacitance Characteristics: Low capacitance (0.1pF @ 0V, 1MHz) essential for RF performance
• Operating Temperature: Full range -65°C ~ 175°C support required
• Frequency Performance: Resistance characteristics at RF frequencies (1MHz minimum)

The DME2458-000 qualifies as a functional equivalent based on matching package type, diode configuration, capacitance specification, and operating temperature range. Voltage and power dissipation parameters are lower but remain within acceptable substitution criteria for applications not requiring the full 4V/150mW specification.

Parameter Comparison

Engineering Selection Recommendations

The DME2458-000 is an active production substitute for the obsolete HSCH-5310. Both components share identical package geometry (2-SMD flat lead), matching capacitance specifications, and equivalent operating temperature ranges. The DME2458-000 provides superior frequency performance with resistance measured at 40GHz versus 1MHz for the original part.

Selection of DME2458-000 is appropriate for applications where the 3V peak reverse voltage and 75mW power dissipation ratings are sufficient. The Skyworks component carries ROHS3 compliance certification, providing regulatory advantage over the REACH-unaffected status of the Broadcom original.

For applications requiring the full 4V/150mW specification of the HSCH-5310, alternative substitutes beyond the provided list must be evaluated.

Frequently Asked Questions (FAQ)

Q: Can DME2458-000 directly replace HSCH-5310 in all applications?

A: Direct replacement is possible only in applications where the circuit design operates within the DME2458-000 voltage (3V maximum) and power dissipation (75mW maximum) limits. The identical package and capacitance characteristics ensure mechanical and electrical interface compatibility.

Q: What is the primary difference between these two parts?

A: The main differences are voltage rating (4V vs 3V), power dissipation (150mW vs 75mW), and product status (obsolete vs active). Both maintain identical capacitance and package specifications.

Q: Are there any compliance or regulatory differences?

A: The DME2458-000 carries ROHS3 compliance certification, while the HSCH-5310 is REACH unaffected. For applications requiring RoHS compliance, the Skyworks substitute provides regulatory advantage.

Q: Does package compatibility guarantee functional equivalence?

A: Package compatibility is necessary but not sufficient for substitution. Electrical parameters including voltage rating, power dissipation, and frequency response must also meet application requirements. Verify circuit design margins before substitution.

Q: What frequency range is each diode rated for?

A: The HSCH-5310 specifies resistance at 1MHz. The DME2458-000 specifies resistance at 40GHz, indicating superior high-frequency performance. Both are suitable for RF applications within their respective frequency ranges.
