AOD607 MOSFET N/P-Channel 30V 12A Equivalent & Substitute Parts

Part Overview

The AOD607 is a complementary N and P-channel MOSFET array designed for surface mount applications in the TO-252-4L package. This device operates at 30V drain-to-source voltage with a continuous drain current rating of 12A at 25°C and a maximum power dissipation of 2.1W. The AOD607 is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support, production continuity, and component sourcing. Substitute parts must maintain electrical compatibility across voltage, current, and thermal specifications while accommodating the same or compatible package configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AOD607 is determined by strict adherence to the following electrical and mechanical parameters:

Voltage Compatibility: The substitute part must maintain a Drain to Source Voltage (Vdss) rating of 30V or greater to ensure safe operation across all specified circuit conditions.

Current Capability: The substitute part must support a continuous drain current (Id) of at least 12A at 25°C to meet or exceed the original device's current handling requirements.

On-State Resistance: The Rds On specification at the rated current and gate voltage must not exceed the original 25 mOhm @ 12A, 10V to prevent excessive power dissipation and thermal stress.

Package Configuration: The substitute must be housed in the TO-252-4L package (DPAK with 4 leads and tab) to ensure mechanical and electrical compatibility with existing PCB layouts and socket designs.

Channel Configuration: The substitute must maintain the N and P-channel complementary configuration to preserve circuit functionality in applications requiring both channel types.

Temperature Range: The substitute must support the operating temperature range of -55°C to 175°C (junction temperature) or a range that encompasses the original specification.

Moisture Sensitivity: The substitute must maintain MSL 1 (Unlimited) classification to ensure compatibility with standard handling and storage protocols.

The AOD607A meets all substitution criteria and is listed as the direct equivalent for the obsolete AOD607.

Parameter Comparison

Engineering Selection Recommendations

The AOD607A is the direct substitute for the obsolete AOD607. Both devices are manufactured by Alpha & Omega Semiconductor Inc. and share identical voltage and package specifications. The AOD607A is classified as Active product status, ensuring ongoing availability and manufacturing support, whereas the AOD607 is obsolete.

The AOD607A demonstrates improved electrical performance characteristics. The on-state resistance at 12A, 10V is 27 mOhm compared to the original 25 mOhm, representing a 2 mOhm increase that remains within acceptable design margins for most applications. The AOD607A offers significantly higher maximum power dissipation ratings (19W and 30W) compared to the original 2.1W, providing enhanced thermal headroom and reliability.

The AOD607A achieves RoHS3 compliance, whereas the original AOD607 compliance status is not specified. Both devices maintain REACH Unaffected status and MSL 1 (Unlimited) moisture sensitivity classification, ensuring compatibility with standard component handling and storage protocols.

The operating temperature range of the AOD607A extends to 150°C (junction temperature), which is 25°C lower than the original 175°C specification. Applications requiring operation above 150°C must evaluate thermal management and derating requirements.

Selection of the AOD607A is appropriate for new designs and production continuity applications requiring the AOD607 specification. The improved power dissipation and active product status provide long-term supply chain stability and manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can the AOD607A directly replace the AOD607 in existing circuit designs?

A: Yes. The AOD607A maintains identical voltage (30V Vdss), current (12A Id), package (TO-252-4L), and channel configuration (N and P-channel complementary) specifications. The on-state resistance increase of 2 mOhm at rated current is negligible for most applications. PCB layouts and socket designs require no modification.

Q: What is the significance of the AOD607 being classified as obsolete?

A: Obsolete classification indicates that the AOD607 is no longer manufactured or supported by Alpha & Omega Semiconductor Inc. Existing inventory may be limited or unavailable. The AOD607A, classified as Active, ensures continued manufacturing support, availability, and supply chain stability for ongoing production and new designs.

Q: How do the power dissipation ratings differ between the AOD607 and AOD607A?

A: The AOD607 is rated for 2.1W maximum power dissipation, while the AOD607A is rated for 19W and 30W. The AOD607A provides significantly higher thermal capacity, reducing junction temperature rise under identical operating conditions and improving device reliability and longevity.

Q: Are there differences in gate charge characteristics between the two devices?

A: Yes. The AOD607 specifies 25 nC gate charge at 10V, while the AOD607A specifies 7 nC and 12 nC at 4.5V. The AOD607A demonstrates lower gate charge at lower gate voltage, potentially improving switching speed and reducing gate drive power requirements in certain circuit topologies.

Q: Does the AOD607A meet environmental and regulatory compliance requirements?

A: The AOD607A is RoHS3 compliant and maintains REACH Unaffected status, meeting current environmental and regulatory standards. Both devices maintain MSL 1 (Unlimited) moisture sensitivity classification, ensuring compatibility with standard component handling protocols.

Q: What is the impact of the 25°C difference in maximum operating temperature?

A: The AOD607A maximum operating temperature is 150°C (junction temperature) compared to the original 175°C. Applications operating near or above 150°C must implement thermal management strategies such as heat sinking, reduced duty cycle, or derating to maintain junction temperature within specification. Most standard applications operating below 125°C are unaffected.

Q: Are the input capacitance values comparable between the two devices?

A: The AOD607 specifies 1250 pF input capacitance at 15V, while the AOD607A specifies 395 pF and 730 pF at 15V. The AOD607A demonstrates lower input capacitance values, which may reduce gate drive current requirements and improve switching performance in high-frequency applications.

Q: Is the AOD607A available in packaging options other than TO-252-4L?

A: The AOD607A is supplied in TO-252-4L package configuration. The supplier device package designation is TO-252-4L (DPAK with 4 leads and tab). No alternative package options are specified for this substitute part.
