DAP222G Equivalent & Substitute Parts

Part Overview

The DAP222G is a general-purpose diode array manufactured by onsemi, configured as a 1 Pair Common Anode device rated for 80 V DC reverse voltage and 100 mA average rectified current per diode. This component is designed for surface mount applications in the SC-75 (SOT-416) package. The part maintains Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical specifications, mechanical packaging, and compliance certifications align with the original component, enabling direct replacement in circuit designs without functional degradation.

Substitute Part Grouping Explanation

Substitution of the DAP222G is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

Diode configuration (1 Pair Common Anode)
Maximum DC reverse voltage (80 V)
Average rectified current per diode (100 mA DC)
Forward voltage drop (1.2 V @ 100 mA)
Reverse recovery time (10 ns)
Reverse leakage current (100 nA @ 70 V)
Maximum junction operating temperature (150°C)

Mechanical & Packaging Requirements:

Package type (SC-75, SOT-416)
Mounting technology (Surface Mount)

Compliance & Environmental:

RoHS3 compliance
Moisture Sensitivity Level (MSL 1)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. The DAP222T1G satisfies all specified parameters and is therefore a valid substitute for the DAP222G.

Both parts are RoHS3 compliant and carry MSL 1 rating, indicating no moisture sensitivity restrictions during storage and handling.

Selection between DAP222G and DAP222T1G should be based on availability and supply chain requirements. The DAP222T1G currently maintains higher inventory levels (62,300 pcs) compared to the DAP222G (1,510 pcs), which may influence procurement decisions for high-volume applications. Both parts are suitable for direct substitution in circuit designs without modification to PCB layout, schematic, or thermal management strategies.

Frequently Asked Questions (FAQ)

Q: Can DAP222T1G replace DAP222G in existing designs?

A: Yes. The DAP222T1G is a parametric equivalent with identical electrical ratings, forward voltage characteristics, reverse recovery time, and package configuration. Direct substitution is supported without circuit redesign.

Q: Are there differences in the SC-75 (SOT-416) package between these parts?

A: No. Both parts use the identical SC-75 (SOT-416) surface mount package with the same pin configuration, footprint, and mechanical dimensions. PCB layout compatibility is guaranteed.

Q: Do both parts meet the same compliance standards?

A: Yes. Both DAP222G and DAP222T1G are RoHS3 compliant, REACH unaffected, and carry MSL 1 rating. Environmental and regulatory compliance is equivalent.

Q: What is the significance of the reverse recovery time (trr) specification?

A: The 10 ns reverse recovery time indicates the speed classification of these diodes as small signal devices. This parameter determines switching performance in high-frequency applications and is identical between both parts.

Q: How do the forward voltage drops compare?

A: Both parts specify 1.2 V maximum forward voltage at 100 mA forward current. Thermal and power dissipation characteristics are therefore equivalent.

Q: Is the reverse leakage current specification the same?

A: Yes. Both parts specify 100 nA maximum reverse leakage current at 70 V reverse bias, indicating identical leakage performance and reliability characteristics.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts are rated for 150°C maximum junction operating temperature, supporting identical thermal operating ranges.
