Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MJD340-13 are qualified based on the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Transistor Type: NPN
• Voltage - Collector Emitter Breakdown (Max): 300 V
• Current - Collector (Ic) (Max): 500 mA
• Current - Collector Cutoff (Max): 100 µA (ICBO)
• DC Current Gain (hFE) (Min) @ Ic, Vce: 30 @ 50mA, 10V
• Power - Max: 15 W

Mechanical Compatibility Criteria:

• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63
• Mounting Type: Surface Mount

Compliance Criteria:

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

All substitute parts listed meet these core parameters. Variations in packaging format (Tape & Reel, Cut Tape, Tube) and operating temperature range do not affect electrical substitutability when the above criteria are satisfied.

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory and supply chain continuity. Selection among MJD340-13, MJD340T4, MJD340G, and MJD340RLG is determined by packaging and temperature range requirements:

MJD340-13 (Diodes Incorporated): Primary specification with operating temperature range of -55°C to 150°C. Supplied in Tape & Reel format. Suitable for applications requiring the full lower temperature specification.

MJD340T4 (STMicroelectronics): Direct electrical equivalent with identical core parameters. Operating temperature specified at 150°C maximum. Supplied in Cut Tape and Digi-Reel® formats. Appropriate for applications where lower temperature operation below -55°C is not required.

MJD340G (onsemi): Electrical equivalent with extended lower operating temperature range (-65°C to 150°C) and specified transition frequency of 10 MHz. Supplied in Tube packaging. Suitable for applications requiring enhanced low-temperature performance or frequency specification.

MJD340RLG (onsemi): Electrical equivalent with extended lower operating temperature range (-65°C to 150°C) and specified transition frequency of 10 MHz. Supplied in Tape & Reel format. Suitable for applications requiring enhanced low-temperature performance with standard reel packaging.

Frequently Asked Questions (FAQ)

Q: Can MJD340T4 replace MJD340-13 in all applications?

A: MJD340T4 is electrically equivalent for all core parameters (voltage, current, gain, power). The primary difference is the specified maximum operating temperature of 150°C versus -55°C to 150°C for MJD340-13. MJD340T4 is suitable for applications where operation below -55°C is not required.

Q: What is the difference between MJD340G and MJD340RLG?

A: Both parts are electrically identical with identical operating temperature ranges (-65°C to 150°C) and transition frequency (10 MHz). The difference is packaging format: MJD340G is supplied in Tube packaging, while MJD340RLG is supplied in Tape & Reel format. Selection depends on assembly line requirements and handling procedures.

Q: Are all substitute parts pin-compatible with MJD340-13?

A: Yes. All substitute parts use the TO-252-3 (DPAK) package with 2 leads plus tab, ensuring identical pinout and PCB footprint compatibility.

Q: Do the onsemi parts (MJD340G and MJD340RLG) offer performance advantages?

A: MJD340G and MJD340RLG specify transition frequency at 10 MHz, whereas MJD340-13 and MJD340T4 do not specify this parameter. Both onsemi parts also extend the lower operating temperature limit to -65°C compared to -55°C for MJD340-13. These specifications do not represent performance upgrades but rather additional characterized parameters suitable for specific application requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: What packaging formats are available?

A: MJD340-13 is supplied in Tape & Reel (TR). MJD340T4 is supplied in Cut Tape (CT) and Digi-Reel®. MJD340G is supplied in Tube. MJD340RLG is supplied in Tape & Reel (TR). Selection depends on assembly equipment compatibility and procurement volume requirements.
