AR4PDHM3_A/I Equivalent & Substitute Parts

Part Overview

The AR4PDHM3_A/I is an avalanche diode manufactured by Vishay General Semiconductor - Diodes Division, classified within the Diodes, Rectifiers category. This surface mount component operates at 200 V DC reverse voltage with a 2 A average rectified current rating and is housed in a TO-277A (SMPC) package. The device is actively produced and carries automotive-grade qualification under AEC-Q101 standards. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or packaging format preferences.

Substitute Part Grouping Explanation

Substitution of the AR4PDHM3_A/I is determined by strict equivalence across all critical electrical parameters and mechanical compatibility. The substitute part AR4PD-M3/86A maintains identical performance specifications across voltage rating, current capacity, forward voltage characteristics, reverse recovery time, leakage current, and junction temperature range. Both components utilize the same TO-277A (SMPC) package configuration and belong to the eSMP® series from Vishay General Semiconductor - Diodes Division.

The primary distinction between the main part and its substitute is the packaging format: AR4PDHM3_A/I is supplied in Tape & Reel (TR) configuration, while AR4PD-M3/86A is supplied in Cut Tape (CT) format. This difference affects procurement and assembly logistics but does not alter electrical or thermal performance. Both parts are Active products with identical RoHS3 compliance, REACH unaffected status, and automotive-grade AEC-Q101 qualification.

Substitution is valid when the following parameters match:

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 1.6 V @ 4 A
• Reverse Recovery Time (trr): 140 ns
• Current - Reverse Leakage @ Vr: 10 µA @ 200 V
• Package / Case: TO-277, 3-PowerDFN
• Operating Temperature - Junction: -55°C to 175°C

Parameter Comparison

Engineering Selection Recommendations

The AR4PD-M3/86A is a direct electrical and mechanical equivalent to the AR4PDHM3_A/I. Both components are manufactured by Vishay General Semiconductor - Diodes Division and carry identical Active product status with AEC-Q101 automotive qualification. Selection between these parts is determined by packaging and supply requirements rather than electrical performance.

Choose AR4PDHM3_A/I when Tape & Reel (TR) packaging is required for automated assembly processes or high-volume production environments.

Choose AR4PD-M3/86A when Cut Tape (CT) packaging is acceptable or preferred for lower-volume applications, prototype development, or when Cut Tape inventory is more readily available.

Both parts satisfy RoHS3 compliance, REACH unaffected status, and EAR99 export classification requirements. The Moisture Sensitivity Level (MSL) rating of 1 (Unlimited) applies to both components, indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can AR4PD-M3/86A be used as a direct replacement for AR4PDHM3_A/I in production assemblies?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tape & Reel versus Cut Tape). If your assembly equipment can accommodate Cut Tape format, AR4PD-M3/86A provides equivalent performance.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on continuous tape wound on a reel, optimized for high-speed automated pick-and-place assembly. Cut Tape packaging supplies components on tape segments of fixed length, typically used for lower-volume applications or manual assembly. Both formats contain the same component in the same TO-277A (SMPC) package.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both AR4PDHM3_A/I and AR4PD-M3/86A have identical electrical specifications, including voltage rating (200 V), current capacity (2 A), forward voltage (1.6 V @ 4 A), reverse recovery time (140 ns), and operating temperature range (-55°C to 175°C).

Q: Do both parts meet automotive qualification standards?

A: Yes. Both components carry AEC-Q101 automotive-grade qualification and are classified as Active products by Vishay General Semiconductor - Diodes Division.

Q: What is the significance of the eSMP® series designation?

A: eSMP® is the Vishay product series designation for these avalanche diodes. Both AR4PDHM3_A/I and AR4PD-M3/86A belong to this series and share the same base product number (AR4).

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts have identical RoHS3 compliance status, REACH unaffected status, EAR99 export classification, and HTSUS code (8541.10.0080). Moisture Sensitivity Level (MSL) is 1 (Unlimited) for both components.

Q: Can these parts be interchanged in existing PCB designs without layout modifications?

A: Yes. Both components use the TO-277A (SMPC) package configuration with identical pinout and mechanical dimensions. No PCB layout changes are required for substitution.
