Engineering Selection Recommendations

BSP89H6327XTSA1 (Infineon Technologies)

This part is the primary parametric equivalent to the BSP89L6327HTSA1. Electrical specifications are identical across all critical parameters: 240V Vdss, 350mA Id, 6 Ohm Rds On, 1.8V Vgs(th), and 6.4 nC gate charge. The primary difference is packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete). The BSP89H6327XTSA1 carries Active product status and ROHS3 compliance, making it the recommended direct replacement for ongoing production and new designs. Inventory availability is substantial at 9130 pieces.

BSP89,115 (Nexperia USA Inc.)

This part offers parametric compatibility with minor variations. Continuous drain current is rated at 375mA (exceeding the 350mA requirement), and Rds On is lower at 5 Ohm. However, gate threshold voltage is specified at 2.0V (0.2V higher than the main part), and power dissipation is reduced to 1.5W. Product status is listed as Not For New Designs, limiting suitability for new applications. This part is suitable for direct replacement in existing designs where the higher Vgs(th) and lower power rating do not create functional constraints.

ZVN4525GTA (Diodes Incorporated)

This part meets the primary voltage and current requirements with 250V Vdss and 310mA Id. However, several parameters deviate from the main part specification. Rds On is higher at 8.5 Ohm (measured at 500mA, 10V), gate charge is significantly lower at 3.65 nC, and input capacitance is substantially reduced at 72 pF. These differences indicate different switching characteristics and may affect circuit performance in applications sensitive to switching speed or gate drive requirements. Product status is Active with ROHS3 compliance. This part is suitable for applications where the higher Rds On and lower gate charge are acceptable trade-offs.

Frequently Asked Questions (FAQ)

Q: Can the BSP89H6327XTSA1 be used as a direct replacement for the BSP89L6327HTSA1?

A: Yes. The BSP89H6327XTSA1 is electrically identical to the BSP89L6327HTSA1 across all critical parameters. The primary difference is packaging format (Tape & Reel) and product status (Active). Both devices are rated for 240V Vdss, 350mA Id, 6 Ohm Rds On, and identical gate charge specifications. The BSP89H6327XTSA1 is recommended for new designs and ongoing production due to its Active status and ROHS3 compliance.

Q: What are the key differences between the BSP89,115 and the main part?

A: The BSP89,115 offers higher continuous drain current (375mA versus 350mA) and lower Rds On (5 Ohm versus 6 Ohm). However, gate threshold voltage is 0.2V higher at 2.0V, and power dissipation is reduced to 1.5W. The product status is Not For New Designs. These differences are acceptable for direct replacement in existing designs where the higher Vgs(th) does not create gate drive complications and the lower power rating is sufficient.

Q: Is the ZVN4525GTA suitable for all applications using the BSP89L6327HTSA1?

A: The ZVN4525GTA meets voltage and current requirements but exhibits different switching characteristics. Rds On is higher at 8.5 Ohm, gate charge is significantly lower at 3.65 nC, and input capacitance is reduced to 72 pF. Applications sensitive to switching speed, gate drive current, or on-state losses may experience performance differences. Verification of circuit performance is necessary before deployment in critical applications.

Q: Are all substitute parts available in the same package?

A: All substitute parts are surface mount SOT-223 family devices. The main part uses PG-SOT223-4-21 packaging, the BSP89H6327XTSA1 uses PG-SOT223-4, and the BSP89,115 and ZVN4525GTA use standard SOT-223 and SOT-223-3 variants respectively. Pin configurations are compatible within the SOT-223 family, but physical footprint verification is recommended during PCB layout.

Q: What is the significance of the Obsolete status for the BSP89L6327HTSA1?

A: Obsolete status indicates that the manufacturer has discontinued production and support for this part. Existing inventory may be available from distributors, but long-term supply cannot be guaranteed. The BSP89H6327XTSA1 is the recommended migration path for new designs and ongoing production support.

Q: Do all substitute parts meet ROHS3 compliance?

A: The BSP89H6327XTSA1, BSP89,115, and ZVN4525GTA are all ROHS3 compliant. The main part (BSP89L6327HTSA1) does not specify RoHS status. For applications requiring ROHS3 compliance, the substitute parts provide documented compliance certification.
