Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BST82,215 are selected based on strict electrical and mechanical compatibility within the following criteria:

Mandatory Matching Parameters:

• FET Type: N-Channel
• Drain to Source Voltage (Vdss): 100V minimum
• Package / Case: TO-236-3, SC-59, or SOT-23-3 (Surface Mount)
• Mounting Type: Surface Mount
• Gate-Source Voltage (Vgs Max): ±20V

Functional Compatibility Parameters:

• Continuous Drain Current (Id): Equal to or greater than 190mA at 25°C
• Rds On (Max): Equal to or less than 10 Ohm at specified conditions
• Vgs(th) (Max): Equal to or less than 2V at 1mA
• Operating Temperature Range: Minimum -55°C to 150°C

The following parts meet these criteria and are classified as direct substitutes or similar alternatives based on their electrical specifications and package compatibility.

Parameter Comparison

Engineering Selection Recommendations

BSS123LT1G (Direct Substitute - onsemi): The BSS123LT1G is classified as a direct substitute for the BST82,215. Both devices share identical Vdss (100V), compatible Vgs(th) specifications, and identical package geometry (SOT-23-3/TO-236). The BSS123LT1G maintains Active product status, ensuring long-term availability and supply chain stability. The continuous drain current of 170mA is within acceptable operating margins for applications designed for 190mA. The lower Rds On (6 Ohm @ 100mA, 10V) provides improved efficiency characteristics. Both parts are ROHS3 Compliant with MSL 1 rating, ensuring compatibility with standard manufacturing processes.

ZVN3310FTA (Similar Alternative - Diodes Incorporated): The ZVN3310FTA is classified as a similar alternative for applications with reduced current requirements. This device maintains the 100V Vdss rating and identical package form factor. The continuous drain current of 100mA is lower than the main part specification, limiting its use to circuits requiring 100mA or less. The Rds On specification (10 Ohm @ 500mA, 10V) matches the main part at the specified condition. The ZVN3310FTA is Active status with ROHS3 compliance and MSL 1 rating. This part is suitable for lower-current applications within the 100V operating envelope.

Both substitute parts are manufactured by established semiconductor suppliers with Active product status, ensuring continued availability and manufacturing consistency. Selection between substitutes depends on application current requirements and thermal management constraints.

Frequently Asked Questions (FAQ)

Q: Can the BSS123LT1G directly replace the BST82,215 in all applications?

A: The BSS123LT1G is electrically compatible for applications requiring continuous drain currents up to 170mA. The 20mA reduction from the original 190mA specification must be evaluated against circuit design margins. Both devices share identical Vdss (100V), package geometry (SOT-23-3), and gate-source voltage ratings (±20V). Thermal performance differs due to lower power dissipation rating (225mW vs. 830mW), which may affect high-power applications.

Q: What are the key differences between BSS123LT1G and ZVN3310FTA?

A: The primary difference is continuous drain current: BSS123LT1G supports 170mA while ZVN3310FTA supports 100mA. Both maintain 100V Vdss and SOT-23-3 packaging. The BSS123LT1G has lower Rds On (6 Ohm @ 100mA, 10V) compared to ZVN3310FTA (10 Ohm @ 500mA, 10V), resulting in better efficiency at moderate current levels. The BSS123LT1G is the preferred substitute for applications requiring higher current capacity.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the SOT-23-3 (TO-236) package with identical pin configuration: Gate (Pin 1), Drain (Pin 2), and Source (Pin 3). Physical board layout and PCB footprints are interchangeable without modification.

Q: Why is the BST82,215 marked as "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and recommends using alternative parts for new circuit designs. The BSS123LT1G and ZVN3310FTA are Active status alternatives suitable for new designs requiring equivalent or similar electrical characteristics.

Q: What compliance certifications apply to all substitute parts?

A: All three parts (BST82,215, BSS123LT1G, and ZVN3310FTA) are ROHS3 Compliant, REACH Unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level). All parts carry ECCN EAR99 classification and HTSUS code 8541.21.0095, ensuring regulatory compatibility across standard manufacturing and distribution channels.

Q: Can the ZVN3310FTA be used in applications designed for 190mA continuous drain current?

A: No. The ZVN3310FTA is rated for 100mA continuous drain current and is not suitable for applications requiring 190mA operation. Using this part in higher-current applications will result in thermal stress and potential device failure. The BSS123LT1G (170mA) is the appropriate substitute for higher-current designs.

Q: What is the operating temperature range compatibility?

A: The BST82,215 operates from -65°C to 150°C. Both substitute parts (BSS123LT1G and ZVN3310FTA) operate from -55°C to 150°C. Applications requiring operation below -55°C must use the original BST82,215 or identify alternative parts with extended low-temperature specifications.
