DPAD50 TO-72 4L ROHS Equivalent & Substitute Parts

Part Overview

The DPAD50 TO-72 4L ROHS is a general-purpose diode array manufactured by Linear Integrated Systems, Inc. This component features two independent diodes in a TO-206AF, TO-72-4 metal can package rated for 45 V DC reverse voltage and 50 mA average rectified current per diode. The part is ROHS3 compliant and carries Active product status.

Substitute parts are necessary when the primary part number becomes unavailable, when inventory constraints require alternative sourcing, or when application-specific leakage current characteristics necessitate selection from the DPAD series variants. All substitute parts maintain identical electrical ratings and mechanical compatibility within the DPAD series.

Key Parameters

Substitute Part Grouping Explanation

All substitute parts within the DPAD series maintain identical specifications for the following critical parameters:

• Diode Configuration: 2 Independent
• Voltage - DC Reverse (Vr) (Max): 45 V
• Current - Average Rectified (Io) (per Diode): 50 mA
• Voltage - Forward (Vf) (Max) @ If: 1.5 V @ 1 mA
• Speed Classification: Small Signal ≤ 200mA (Io), Any Speed
• Operating Temperature - Junction: -55°C to 150°C
• Mounting Type: Through Hole
• Package / Case: TO-206AF, TO-72-4 Metal Can
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The primary differentiating parameter among DPAD series variants is Current - Reverse Leakage @ Vr (measured at 20 V). This parameter varies across the substitute parts and determines selection based on application leakage requirements. All parts are manufactured by Linear Integrated Systems, Inc., carry Active product status, and are suitable for direct substitution in through-hole PCB applications.

Parameter Comparison

Engineering Selection Recommendations

All DPAD series parts listed are manufactured by Linear Integrated Systems, Inc. and carry Active product status. Each part is ROHS3 compliant and carries MSL Level 1 (Unlimited) moisture sensitivity classification, indicating no special storage or handling requirements.

Selection among DPAD series variants is determined by application requirements for reverse leakage current at 20 V. The DPAD50 TO-72 4L ROHS exhibits 50 pA reverse leakage. Lower leakage variants (DPAD1 through DPAD20) are suitable for applications requiring reduced leakage characteristics. Higher leakage variants (DPAD100) are suitable for general-purpose applications with relaxed leakage specifications.

All parts utilize identical TO-206AF, TO-72-4 metal can through-hole packaging and are mechanically and electrically interchangeable within the DPAD series. Compliance certifications (ROHS3, REACH Unaffected, EAR99 ECCN classification) are consistent across all variants.

Frequently Asked Questions (FAQ)

Q: Are all DPAD series parts electrically interchangeable with DPAD50 TO-72 4L ROHS?

A: Yes. All DPAD series variants maintain identical voltage ratings (45 V DC reverse), current ratings (50 mA average rectified per diode), forward voltage characteristics (1.5 V @ 1 mA), operating temperature range (-55°C to 150°C), and package configuration (TO-206AF, TO-72-4 metal can). The primary difference is reverse leakage current at 20 V, which varies by part number.

Q: What is the significance of reverse leakage current variation across DPAD variants?

A: Reverse leakage current is the small current that flows through a diode when reverse biased. DPAD variants range from 1 pA (DPAD1) to 100 pA (DPAD100) at 20 V. Applications sensitive to leakage current should select lower-leakage variants. Applications with relaxed leakage specifications can use higher-leakage variants.

Q: Can DPAD50 TO-72 4L ROHS be replaced with DPAD10 TO-72 4L ROHS?

A: Yes. Both parts are ROHS3 compliant, carry Active product status, and share identical mechanical and electrical specifications except for reverse leakage current (50 pA versus 10 pA at 20 V). DPAD10 exhibits lower leakage and is a direct substitute.

Q: Are there any differences in RoHS compliance between DPAD variants?

A: All DPAD series parts listed are ROHS3 compliant. REACH status is Unaffected for all variants. ECCN classification is EAR99 for all parts.

Q: What is the moisture sensitivity level for DPAD series diode arrays?

A: All DPAD series parts carry MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions. These components do not require special dry-pack storage or baking procedures prior to assembly.

Q: Are DPAD series parts suitable for surface-mount applications?

A: No. All DPAD series parts utilize through-hole mounting in TO-206AF, TO-72-4 metal can packages. These components are designed for through-hole PCB assembly only.

Q: What is the difference between TO-206AF and TO-72-4 package designations?

A: TO-206AF and TO-72-4 are equivalent designations for the same metal can package used in DPAD series diode arrays. Both refer to the four-lead through-hole metal can configuration.
