MJD350G Equivalent & Substitute Parts

Part Overview

The MJD350G is a PNP bipolar junction transistor manufactured by onsemi, rated for 300 V collector-emitter breakdown voltage and 500 mA maximum collector current in a surface mount DPAK package. This device is classified as obsolete, which necessitates identification of equivalent and substitute parts for ongoing design support and procurement continuity. Active alternatives with identical or compatible electrical and mechanical specifications are available from both onsemi and alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MJD350G is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Transistor type: PNP
• Maximum collector current: 500 mA
• Maximum collector-emitter breakdown voltage: 300 V
• Maximum collector cutoff current: 100 µA
• Minimum DC current gain (hFE): 30 @ 50mA, 10V
• Maximum power dissipation: 15 W
• Operating temperature range: -65°C to 150°C (TJ)

Mechanical Equivalence Criteria:

• Mounting type: Surface Mount
• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63
• Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed maintain full electrical and mechanical compatibility with the MJD350G within these defined parameters. Variations in product status, packaging format (Cut Tape, Tape & Reel), and compliance certifications do not affect functional interchangeability in circuit applications.

Engineering Selection Recommendations

Primary Recommendation: MJD350T4G

MJD350T4G is the preferred substitute for MJD350G. This part is manufactured by onsemi with active product status, ensuring long-term availability and supply chain stability. It maintains complete electrical and thermal equivalence with the obsolete MJD350G across all critical parameters. MJD350T4G carries ROHS3 compliance certification, meeting modern environmental and regulatory requirements. Packaging is available in Cut Tape (CT) and Digi-Reel® formats, supporting both prototype and production volume requirements.

Secondary Recommendation: MJD350-13

MJD350-13, manufactured by Diodes Incorporated, provides an alternative from a different supplier with active product status. This part meets all electrical specifications and maintains identical mechanical compatibility. Operating temperature range is -55°C to 150°C (TJ), which is narrower than the MJD350G specification of -65°C to 150°C (TJ). MJD350-13 is ROHS3 compliant and available in Tape & Reel (TR) packaging. Selection of this part is appropriate for applications where the lower temperature limit of -55°C is acceptable.

Tertiary Recommendation: NJVMJD350T4G

NJVMJD350T4G is an active onsemi product with ROHS3 compliance. This part exhibits reduced maximum power dissipation of 1.56 W compared to the 15 W specification of MJD350G. NJVMJD350T4G includes a specified transition frequency of 10 MHz. This part is suitable for applications where power dissipation requirements are lower than the original specification. Tape & Reel (TR) packaging is standard for this variant.

Not Recommended: MJD350T4

MJD350T4 is classified as obsolete with RoHS non-compliant status. While electrically equivalent to MJD350G, the obsolete product status and lack of modern compliance certifications make this part unsuitable for new designs or long-term procurement strategies.

Frequently Asked Questions (FAQ)

Q: Can MJD350T4G be used as a direct replacement for MJD350G in existing designs?

A: Yes. MJD350T4G is electrically and mechanically equivalent to MJD350G across all specified parameters. The TO-252-3 DPAK package is identical, and all electrical ratings match or exceed the original specification. No circuit modifications are required.

Q: What is the difference between MJD350T4G and NJVMJD350T4G?

A: Both are onsemi PNP transistors in TO-252-3 DPAK packages with identical electrical ratings for collector current, breakdown voltage, and current gain. The primary difference is maximum power dissipation: MJD350T4G is rated for 15 W, while NJVMJD350T4G is rated for 1.56 W. NJVMJD350T4G also specifies a transition frequency of 10 MHz. Selection depends on the thermal and frequency requirements of the application.

Q: Why is MJD350-13 from Diodes Incorporated listed as a substitute?

A: MJD350-13 maintains electrical equivalence across all critical parameters: 500 mA collector current, 300 V breakdown voltage, 30 hFE minimum, and 15 W power rating. The TO-252-3 DPAK package is identical. The operating temperature range is -55°C to 150°C (TJ), which is narrower than MJD350G at -65°C to 150°C (TJ). This part is suitable for applications where the lower temperature limit of -55°C is acceptable.

Q: Is MJD350T4 a viable substitute?

A: MJD350T4 is electrically equivalent but carries obsolete product status and RoHS non-compliant certification. For new designs and long-term procurement, MJD350T4G or MJD350-13 are preferred alternatives with active status and modern compliance certifications.

Q: What packaging formats are available for these substitute parts?

A: MJD350T4G is available in Cut Tape (CT) and Digi-Reel® formats. NJVMJD350T4G and MJD350-13 are supplied in Tape & Reel (TR) format. All parts share the same TO-252-3 DPAK mechanical package, ensuring PCB footprint compatibility.

Q: Are all substitute parts ROHS3 compliant?

A: MJD350T4G, NJVMJD350T4G, and MJD350-13 are all ROHS3 compliant. MJD350T4 is RoHS non-compliant. For applications requiring environmental compliance certification, select from the three ROHS3-compliant alternatives.

Q: What is the moisture sensitivity level for these parts?

A: All listed parts, including MJD350G and all substitutes, carry Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
