FOD3180V Equivalent & Substitute Parts

Part Overview

The FOD3180V is a 2.5A gate driver optical coupler manufactured by onsemi, providing 5000Vrms isolation in an 8-DIP through-hole package. This component is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. The FOD3180V serves applications requiring high-voltage isolation in gate driver circuits, particularly in power conversion and motor control systems.

Substitute Part Grouping Explanation

Substitution for the FOD3180V is determined by the following critical parameters:

Primary Substitution Criteria:

Single-channel optical coupling gate driver architecture
8-DIP through-hole package (0.300", 7.62mm)
2.5A peak output current capability
2A output high and low current ratings
Operating temperature range compatibility (-40°C minimum)

Secondary Compatibility Factors:

Isolation voltage rating (FOD3180V specifies 5000Vrms; lower ratings acceptable for applications not requiring maximum isolation)
Common mode transient immunity (FOD3180V: 15kV/µs minimum)
Output supply voltage range (FOD3180V: 10V ~ 20V)
Propagation delay and pulse width distortion characteristics

The substitute parts listed below maintain the core functional requirements of single-channel gate driver operation with equivalent output current specifications and package form factor. Isolation voltage ratings of 3750Vrms represent a reduction from the original 5000Vrms specification and are suitable for applications where lower isolation margins are acceptable.

Engineering Selection Recommendations

All listed substitute parts are active Broadcom Limited products with ROHS3 compliance, addressing the obsolescence of the FOD3180V. Selection among substitutes depends on specific application requirements:

ACPL-312T-000E and ACPL-312U-000E are automotive-grade components qualified to AEC-Q100, suitable for automotive and industrial applications requiring extended temperature operation to 125°C.

ACPL-3130-000E and ACPL-3130-060E provide the highest common mode transient immunity at 40kV/µs, beneficial for applications with severe dV/dt conditions.

ACPL-J313-000E offers 40kV/µs common mode transient immunity with forward voltage of 1.6V, suitable for high-speed switching applications.

ACPL-T350-000E combines 15kV/µs common mode transient immunity matching the FOD3180V with significantly faster rise and fall times (15ns, 20ns), enabling higher-frequency gate drive applications.

HCPL-3120-000E and HCPL-3120-060E provide 25kV/µs common mode transient immunity with standard propagation delay characteristics and are available in high inventory quantities.

All substitutes maintain the 2.5A peak output current and 2A continuous output current specifications. Output supply voltage ranges extend to 30V maximum, requiring circuit verification for applications operating at the FOD3180V's 10V minimum. Isolation voltage reduction from 5000Vrms to 3750Vrms must be evaluated against application isolation requirements.

Frequently Asked Questions (FAQ)

Q: Can ACPL-312T-000E directly replace FOD3180V in existing designs?

A: Direct replacement requires verification of three parameters: output supply voltage (ACPL-312T-000E operates 15V ~ 30V versus FOD3180V 10V ~ 20V), isolation voltage (3750Vrms versus 5000Vrms), and common mode transient immunity (25kV/µs versus 15kV/µs). Pin-to-pin compatibility exists for the 8-DIP package, but circuit operation must be confirmed.

Q: What is the primary difference between ACPL-3130-000E and ACPL-3130-060E?

A: Both parts are electrically identical with 40kV/µs common mode transient immunity and 3750Vrms isolation. The "-060E" suffix indicates a different packaging or qualification variant. Consult Broadcom datasheets for specific packaging differences.

Q: Why do substitute parts have lower isolation voltage (3750Vrms) than FOD3180V (5000Vrms)?

A: The 3750Vrms rating is sufficient for most gate driver applications where isolation is required for safety and noise immunity rather than extreme voltage stress. Applications requiring 5000Vrms isolation should evaluate ACPL-T350-000E or consult Broadcom for higher-isolation alternatives.

Q: Is ACPL-T350-000E suitable for high-frequency switching applications?

A: Yes. ACPL-T350-000E provides rise and fall times of 15ns and 20ns respectively, significantly faster than the FOD3180V (75ns, 55ns) and other substitutes (100ns, 100ns). This enables operation at higher switching frequencies with reduced propagation delay variation.

Q: Are all substitute parts RoHS compliant?

A: All listed Broadcom substitutes are ROHS3 compliant. The FOD3180V RoHS status is not specified in available documentation.

Q: What is the inventory status of substitute parts?

A: HCPL-3120-000E has the highest inventory at 25,400 pieces. ACPL-312T-000E has 73,508 pieces available. Other variants range from 972 to 5,400 pieces. Inventory levels should be confirmed with suppliers for production requirements.
