Engineering Selection Recommendations

STN1HNK60 (STMicroelectronics)

The STN1HNK60 is an active product with higher voltage (600V) and current (400mA) ratings compared to the BSP130,115. This part exceeds the electrical requirements of the original device. The STN1HNK60 features SuperMESH™ technology and is RoHS3 compliant with unlimited MSL. With 29,200 units in stock, this part offers superior availability. The higher power dissipation rating (3.3W) provides additional thermal margin. This substitute is suitable for applications where the higher voltage rating does not create design constraints.

STN1NK60Z (STMicroelectronics)

The STN1NK60Z is an active product rated for 600V and 300mA continuous drain current. While the voltage rating exceeds the BSP130,115 specification, the current rating falls below the original 350mA requirement. This part is suitable only for applications where the actual operating current does not exceed 300mA. The STN1NK60Z features SuperMESH™ technology and is RoHS3 compliant. With 65,400 units in stock, this part offers the highest availability among all substitutes. The lower input capacitance (94pF) may provide switching speed advantages in certain circuit topologies.

ZVN2120GTA (Diodes Incorporated)

The ZVN2120GTA is an active product with a lower voltage rating (200V) compared to the BSP130,115 (300V). This part is suitable only for applications where the operating voltage does not exceed 200V. The continuous drain current (320mA) is slightly below the original specification (350mA). The ZVN2120GTA is RoHS3 compliant with unlimited MSL and offers 15,880 units in stock. The lower input capacitance (85pF) and lower power dissipation (2W) may be advantageous in low-power switching applications.

ZVNL120GTA (Diodes Incorporated)

The ZVNL120GTA is an active product with a lower voltage rating (200V) and reduced gate threshold voltage (1.5V @ 1mA) compared to the BSP130,115. This part is suitable only for applications where the operating voltage does not exceed 200V and where lower gate drive voltage is beneficial. The continuous drain current (320mA) is slightly below the original specification. The ZVNL120GTA is RoHS3 compliant with unlimited MSL. With 2,503 units in stock, this part has the lowest availability among all substitutes. The lower threshold voltage enables operation with reduced gate drive requirements.

Frequently Asked Questions (FAQ)

Q: Can the STN1HNK60 directly replace the BSP130,115 in all applications?

A: The STN1HNK60 meets or exceeds all electrical specifications of the BSP130,115 and shares the same SOT-223 package. However, the higher voltage rating (600V vs. 300V) may affect circuit behavior in applications with voltage-dependent characteristics. Verification of circuit performance is necessary when substituting parts with different voltage ratings.

Q: Why does the STN1NK60Z have a lower current rating than the BSP130,115?

A: The STN1NK60Z is rated for 300mA continuous drain current, which is below the BSP130,115 specification of 350mA. This part is suitable only for applications where the actual operating current does not exceed 300mA. The higher voltage rating (600V) does not compensate for the lower current capability.

Q: Are the ZVN2120GTA and ZVNL120GTA suitable substitutes for high-voltage applications?

A: No. Both the ZVN2120GTA and ZVNL120GTA are rated for 200V maximum drain-to-source voltage, which is below the BSP130,115 specification of 300V. These parts are suitable only for applications where the operating voltage does not exceed 200V.

Q: What is the difference between the ZVN2120GTA and ZVNL120GTA?

A: Both parts share identical voltage (200V) and current (320mA) ratings and input capacitance (85pF). The primary difference is the gate threshold voltage: ZVN2120GTA is specified at 3V @ 1mA, while ZVNL120GTA is specified at 1.5V @ 1mA. The ZVNL120GTA also specifies drive voltage at 3V and 5V, enabling operation with lower gate drive levels.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (STN1HNK60, STN1NK60Z, ZVN2120GTA, and ZVNL120GTA) are RoHS3 compliant with unlimited moisture sensitivity level (MSL 1), matching the compliance status of the BSP130,115.

Q: Which substitute part offers the best availability?

A: The STN1NK60Z offers the highest inventory with 65,400 units in stock, followed by the STN1HNK60 with 29,200 units. The ZVN2120GTA has 15,880 units available, and the ZVNL120GTA has the lowest availability with 2,503 units.

Q: Can I use a substitute part with a higher power dissipation rating?

A: Yes. Parts with higher power dissipation ratings (such as the STN1HNK60 and STN1NK60Z at 3.3W compared to the BSP130,115 at 1.5W) provide additional thermal margin and are acceptable substitutes from a thermal perspective. However, the actual power dissipation in your circuit depends on operating conditions and load characteristics.

Q: Are the SOT-223 and SOT-223-3 packages pin-compatible?

A: Both package designations refer to the same physical SOT-223 form factor (TO-261-4, TO-261AA). The "-3" designation in SOT-223-3 indicates a 3-pin configuration, which is standard for this package type. All listed parts use compatible SOT-223 packaging.
