DAN222 Equivalent & Substitute Parts Reference

Part Overview

The DAN222 is a dual switching diode in common cathode configuration rated for 80V DC reverse voltage and 100mA average rectified current per diode. Manufactured by onsemi in SC-75 (SOT-416) surface mount package, this component is classified as obsolete product status. Due to its obsolete classification, identifying functionally equivalent active alternatives is essential for design continuity and procurement planning. Substitute parts must maintain the common cathode diode pair configuration while meeting or exceeding the electrical performance specifications of the original device.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DAN222 is determined by the following mandatory parameters:

• Diode Configuration: Must be 1 Pair Common Cathode to maintain circuit compatibility
• Voltage Rating: Reverse voltage (Vr) must be ≥80V to ensure adequate voltage margin
• Current Rating: Average rectified current (Io) must be ≥100mA per diode to support circuit requirements
• Technology: Standard small signal diode technology (≤200mA Io classification)
• Mounting Type: Surface mount only
• Reverse Recovery Time: ≤4ns for switching performance consistency

Three active substitute parts meet these criteria with varying package options and enhanced electrical specifications. All substitutes are RoHS3 compliant and maintain MSL-1 moisture sensitivity rating.

Parameter Comparison

Engineering Selection Recommendations

DAN222G (onsemi) provides the closest electrical and mechanical match to the DAN222. This part maintains identical voltage and current ratings (80V, 100mA) and uses the same SC-75 SOT-416 package, requiring no PCB layout modifications. DAN222G is active product status with ROHS3 compliance, making it the preferred direct replacement for new designs and existing inventory transitions.

BAV70M,315 (Nexperia USA Inc.) offers enhanced electrical specifications with 100V reverse voltage rating and 150mA current capability, providing additional design margin. The SOT-883 package is physically smaller than SOT-416, requiring PCB footprint verification before implementation. This part is suitable for applications where increased voltage headroom is beneficial.

BAV70TB_R1_00001 (Panjit International Inc.) provides 150mA current rating with extended operating temperature range (-55°C to 150°C). The SOT-523 package is the smallest of the three alternatives. The 75V reverse voltage rating is below the DAN222 specification and requires circuit voltage analysis to confirm adequacy for the application.

All three substitutes maintain common cathode configuration, small signal switching characteristics, and MSL-1 moisture sensitivity. Selection should prioritize package compatibility with existing PCB designs and voltage margin requirements for the specific application circuit.

Frequently Asked Questions (FAQ)

Q: Can DAN222G be used as a direct replacement without PCB modifications?

A: Yes. DAN222G uses the identical SC-75 SOT-416 package as the DAN222, requiring no footprint changes. Electrical specifications are matched at 80V and 100mA ratings.

Q: What is the key difference between the three substitute options?

A: Package size and voltage rating vary. DAN222G matches the original package (SOT-416). BAV70M,315 uses SOT-883 (smaller) with higher 100V rating. BAV70TB_R1_00001 uses SOT-523 (smallest) with 75V rating. All maintain 1 Pair Common Cathode configuration and 4ns reverse recovery time.

Q: Is BAV70TB_R1_00001 suitable if the circuit operates at 80V?

A: The 75V reverse voltage rating of BAV70TB_R1_00001 is below the DAN222 specification. Circuit analysis is required to determine if 75V provides adequate margin for the application's maximum voltage conditions and transient peaks.

Q: Are all substitutes RoHS compliant?

A: Yes. DAN222G, BAV70M,315, and BAV70TB_R1_00001 are all ROHS3 compliant, unlike the original DAN222 which is RoHS non-compliant. This improves environmental compliance for new designs.

Q: What is the impact of different package sizes on circuit design?

A: DAN222G (SOT-416) requires no layout changes. BAV70M,315 (SOT-883) and BAV70TB_R1_00001 (SOT-523) have different footprints and may require PCB redesign. Verify pad spacing, trace routing, and thermal considerations before selecting smaller packages.

Q: Do all substitutes have the same moisture sensitivity level?

A: Yes. All parts including the original DAN222 are classified as MSL-1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
