BSS100 Equivalent & Substitute Parts

Part Overview

The BSS100 is an N-Channel MOSFET manufactured by onsemi, rated for 100V drain-to-source voltage with a continuous drain current of 220mA at 25°C. The device is packaged in a TO-92-3 through-hole configuration and is classified as obsolete. Due to its obsolete product status, identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BSS100 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Drain to Source Voltage (Vdss) must equal or exceed 100V
• Continuous drain current (Id) must meet or exceed 220mA at 25°C
• Gate threshold voltage (Vgs(th)) must be compatible with existing gate drive circuits
• On-state resistance (Rds On) must not significantly degrade circuit performance

Mechanical Compatibility Requirements:

• Mounting type must be through-hole
• Package must be TO-92-3 or equivalent TO-226-3 footprint

Compliance Considerations:

• Active product status is preferred for long-term availability
• RoHS compliance status should be evaluated for regulatory requirements

The ZVN2110A from Diodes Incorporated meets all electrical and mechanical compatibility criteria while offering improved specifications and active product status.

Engineering Selection Recommendations

ZVN2110A as Primary Substitute:

The ZVN2110A is a direct functional substitute for the BSS100. Both devices share identical voltage ratings (100V Vdss) and compatible package configurations (TO-92-3 through-hole). The ZVN2110A provides superior electrical performance with 320mA continuous drain current compared to the BSS100's 220mA, and lower on-state resistance (4 Ohm at 1A, 10V versus 6 Ohm at 220mA, 10V).

Compliance Advantages:

The ZVN2110A holds active product status, ensuring long-term availability and supply chain stability. The device is ROHS3 compliant, meeting current regulatory requirements for electronic components in restricted substance directives. The BSS100, classified as obsolete and RoHS non-compliant, presents supply and regulatory risks for new designs and production continuity.

Electrical Performance:

The ZVN2110A's improved specifications (higher current rating, lower on-state resistance, and higher power dissipation capability at 700mW) provide design margin and enhanced thermal performance. Gate threshold voltage remains within compatible operating ranges (2.4V maximum for ZVN2110A versus 2V for BSS100), ensuring compatibility with existing gate drive circuits.

Mechanical Compatibility:

Both devices utilize identical through-hole mounting and TO-92-3 package footprints, enabling direct board-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the ZVN2110A directly replace the BSS100 in existing designs?

A: Yes. Both devices share identical voltage ratings (100V Vdss), compatible package configurations (TO-92-3 through-hole), and N-Channel MOSFET topology. The ZVN2110A provides equal or superior electrical performance across all critical parameters.

Q: What are the key differences between the BSS100 and ZVN2110A?

A: The ZVN2110A offers higher continuous drain current (320mA versus 220mA), lower on-state resistance (4 Ohm versus 6 Ohm), and active product status with ROHS3 compliance. The BSS100 is obsolete and RoHS non-compliant. Gate threshold voltage differs slightly (2.4V versus 2V), remaining within compatible operating ranges.

Q: Are there any circuit design considerations when substituting the ZVN2110A for the BSS100?

A: No circuit redesign is required. The ZVN2110A's improved electrical characteristics (lower Rds On, higher current rating) provide enhanced performance without requiring gate drive circuit modifications. Gate threshold voltage compatibility ensures proper switching operation with existing drive circuits.

Q: What is the impact of the ZVN2110A's higher input capacitance (75 pF versus 60 pF)?

A: The 15 pF increase in input capacitance has minimal impact on most applications. This parameter affects gate charge and switching speed. For high-frequency switching applications, the difference is negligible given the ZVN2110A's lower on-state resistance and improved thermal performance.

Q: Why is product status important when selecting a substitute?

A: Active product status ensures long-term component availability, stable pricing, and continued manufacturer support. The BSS100's obsolete classification creates supply chain risk and may result in counterfeit or aged inventory. The ZVN2110A's active status guarantees reliable sourcing for production and repair applications.

Q: Does the ZVN2110A require different PCB footprint or mounting procedures?

A: No. Both devices use identical TO-92-3 through-hole packaging with the same lead configuration and spacing. Direct board-level substitution is possible without layout modifications or re-qualification of assembly processes.

Q: What is the significance of ROHS3 compliance for the ZVN2110A?

A: ROHS3 compliance indicates the device meets current European Union Restriction of Hazardous Substances directives, restricting lead, cadmium, mercury, and other hazardous materials. This compliance is required for products sold in regulated markets and is essential for new designs and long-term production continuity.
