MJD350-13 Equivalent & Substitute Parts

Part Overview

The MJD350-13 is a surface mount PNP bipolar junction transistor manufactured by Diodes Incorporated, rated for 300 V collector-emitter breakdown voltage and 500 mA maximum collector current in a TO-252-3 (DPAK) package. This device is classified as Active product status with full RoHS3 compliance. Substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required, or when sourcing from different manufacturers is preferred while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MJD350-13 is determined by electrical parameter equivalence and mechanical compatibility. All substitute parts must satisfy the following criteria:

Electrical Equivalence Requirements:

• Transistor type: PNP configuration
• Collector current rating: 500 mA minimum
• Collector-emitter breakdown voltage: 300 V minimum
• DC current gain (hFE): 30 minimum @ 50mA, 10V
• Collector cutoff current: 100 µA maximum
• Operating temperature range: Must encompass or exceed -55°C to 150°C

Mechanical Compatibility Requirements:

• Package type: TO-252-3 (DPAK) with 2 leads plus tab
• Mounting type: Surface mount
• Pin configuration: Functionally equivalent base, collector, and emitter connections

The substitute parts MJD350T4, MJD350T4G, and NJVMJD350T4G meet these electrical and mechanical criteria. Differences in power dissipation rating, frequency response, and product status are noted but do not preclude substitution when the application requirements are satisfied by the substitute part's specifications.

Engineering Selection Recommendations

Primary Substitute: MJD350T4G

The MJD350T4G is the recommended substitute for the MJD350-13. Both parts are Active product status, RoHS3 compliant, and electrically equivalent across all critical parameters. The MJD350T4G is available in Cut Tape and Digi-Reel packaging formats with significantly higher inventory availability (104,596 units). The extended operating temperature range (-65°C to 150°C) provides additional margin beyond the MJD350-13 specification.

Secondary Substitute: NJVMJD350T4G

The NJVMJD350T4G is an Active, RoHS3-compliant alternative with identical electrical parameters and operating temperature range. This part includes specified transition frequency (10 MHz) and reduced power dissipation rating (1.56 W). Selection of this part is appropriate when application requirements do not exceed the 1.56 W power specification and when the 10 MHz frequency response is beneficial or required.

Not Recommended: MJD350T4

The MJD350T4 carries Obsolete product status and is non-compliant with RoHS3 requirements. While electrically equivalent, this part should not be selected for new designs or applications requiring regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can MJD350T4G be used as a direct replacement for MJD350-13?

A: Yes. The MJD350T4G meets all electrical and mechanical compatibility requirements. Both parts are rated for 500 mA collector current, 300 V breakdown voltage, and operate in the TO-252-3 package. Both are RoHS3 compliant and Active product status.

Q: What is the difference between MJD350T4G and NJVMJD350T4G?

A: The primary differences are power dissipation rating and frequency response. The MJD350T4G is rated for 15 W maximum power dissipation with unspecified transition frequency. The NJVMJD350T4G is rated for 1.56 W maximum power dissipation with 10 MHz transition frequency specified. Both maintain identical DC electrical parameters and operating temperature range.

Q: Why is MJD350T4 listed as a substitute if it is obsolete?

A: MJD350T4 is electrically equivalent but carries Obsolete product status and lacks RoHS3 compliance. It is included in the substitute list for reference and legacy system support only. New designs should not incorporate this part.

Q: Are there packaging format differences between the substitutes?

A: Yes. The MJD350-13 is supplied in Tape & Reel format. The MJD350T4G is available in Cut Tape and Digi-Reel formats. The NJVMJD350T4G is supplied in Tape & Reel format. Packaging format selection depends on assembly process requirements and volume specifications.

Q: What is the operating temperature difference between MJD350-13 and the substitute parts?

A: The MJD350-13 operates from -55°C to 150°C. All substitute parts (MJD350T4, MJD350T4G, NJVMJD350T4G) operate from -65°C to 150°C, providing an additional 10°C margin at the lower temperature extreme.

Q: Can NJVMJD350T4G be used in applications requiring 15 W power dissipation?

A: No. The NJVMJD350T4G is rated for maximum 1.56 W power dissipation. Applications requiring 15 W dissipation must use MJD350-13 or MJD350T4G.

Q: Are all substitute parts RoHS3 compliant?

A: No. MJD350T4 is RoHS non-compliant. MJD350T4G and NJVMJD350T4G are both RoHS3 compliant. The MJD350-13 is also RoHS3 compliant.
