MSQ1PJ-M3/H Equivalent & Substitute Parts

Part Overview

The MSQ1PJ-M3/H is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount diode operates at 600 V DC reverse voltage with 1 A average rectified current and is housed in the MicroSMP (DO-219AD) package. The device is classified as Active product status and complies with RoHS3 and REACH regulations.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter set. Alternative part numbers may be required due to inventory availability, supply chain considerations, or specific application qualifications such as automotive certification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSQ1PJ-M3/H is determined by equivalence across the following critical parameters:

Electrical Parameters:

• Voltage - DC Reverse (Vr) (Max): 600 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.2 V @ 1 A
• Reverse Recovery Time (trr): 650 ns
• Current - Reverse Leakage @ Vr: 1 µA @ 600 V
• Capacitance @ Vr, F: 4 pF @ 4V, 1MHz

Mechanical Parameters:

• Package / Case: MicroSMP (DO-219AD)
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 175°C

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

Substitute parts must match all electrical specifications, maintain identical package and mounting characteristics, and satisfy the same regulatory compliance requirements. Variations in product qualification (such as automotive certification) do not disqualify substitution when all core parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

MSQ1PJHM3/H is a direct parametric equivalent to the MSQ1PJ-M3/H. Both devices are manufactured by Vishay General Semiconductor - Diodes Division and share identical electrical specifications, package configuration, and regulatory compliance status.

The MSQ1PJHM3/H carries additional automotive qualification (AEC-Q101) and is designated for automotive-grade applications. This qualification does not alter the core electrical or mechanical parameters and does not restrict its use in non-automotive applications where the MSQ1PJ-M3/H is specified.

Both parts maintain Active product status, comply with RoHS3 and REACH requirements, and operate across the identical temperature range of -55°C to 175°C junction temperature. Selection between these parts is determined by application requirements, inventory availability, and supply chain considerations rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can MSQ1PJHM3/H replace MSQ1PJ-M3/H in existing designs?

A: Yes. The MSQ1PJHM3/H is electrically and mechanically equivalent to the MSQ1PJ-M3/H across all specified parameters. Both devices operate at 600 V reverse voltage, 1 A average rectified current, and are housed in the MicroSMP (DO-219AD) package. Direct substitution is supported without design modification.

Q: What is the difference between MSQ1PJ-M3/H and MSQ1PJHM3/H?

A: The MSQ1PJHM3/H includes automotive-grade qualification (AEC-Q101), while the MSQ1PJ-M3/H does not carry this designation. All electrical performance, thermal characteristics, and package specifications are identical. The automotive qualification does not restrict use in non-automotive applications.

Q: Are both parts available in the same packaging format?

A: Yes. Both MSQ1PJ-M3/H and MSQ1PJHM3/H are supplied in Tape & Reel (TR) packaging with MicroSMP (DO-219AD) surface mount configuration. PCB assembly processes and handling requirements are identical for both parts.

Q: What are the critical parameters for substitution?

A: Substitution is valid when the following parameters match: Voltage - DC Reverse (Vr) at 600 V, Current - Average Rectified (Io) at 1 A, Voltage - Forward (Vf) at 1.2 V @ 1 A, Reverse Recovery Time (trr) at 650 ns, Current - Reverse Leakage at 1 µA @ 600 V, Capacitance at 4 pF @ 4V, 1MHz, and MicroSMP (DO-219AD) package configuration.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both MSQ1PJ-M3/H and MSQ1PJHM3/H are ROHS3 Compliant, REACH Unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). Regulatory compliance is equivalent across both part numbers.

Q: What is the operating temperature range for these diodes?

A: Both devices operate across a junction temperature range of -55°C to 175°C, supporting applications in industrial, commercial, and automotive environments within this thermal specification.
