• Vce Saturation: 400 mV @ 5 mA, 50 mA
• Maximum Collector Cutoff Current: 50 nA
• Minimum DC Current Gain (hFE): 100 @ 10 mA, 1 V
• Maximum Power Dissipation: 150 mW
• Transition Frequency: 250 MHz
• Operating Temperature Range: -55°C to 150°C

Mechanical Parameters (Must Match):

• Package Type: SOT-523
• Mounting Type: Surface Mount

Compliance Parameters (Must Match):

• RoHS3 Compliance
• Moisture Sensitivity Level: 1 (Unlimited)
• Automotive Grade
• AEC-Q101 Qualification

Substitute parts identified below meet all electrical, mechanical, and compliance requirements and are therefore direct functional equivalents suitable for circuit-level replacement.

Parameter Comparison

Engineering Selection Recommendations

MMBT3906T-7-F (Diodes Incorporated) is the primary parametric equivalent substitute for the MMBT3906T-13. This part maintains identical electrical specifications, operates within the same temperature range, and carries Active product status. Both components are manufactured by Diodes Incorporated, share the same base product number (MMBT3906), and meet AEC-Q101 automotive qualification and ROHS3 compliance requirements. The MMBT3906T-7-F is supplied in Tape & Reel packaging format, providing improved supply chain availability compared to the Obsolete MMBT3906T-13.

MMBT3906T-TP (Micro Commercial Co) is an alternative substitute that matches all critical electrical and mechanical parameters. This part is manufactured by a different supplier and is available in Active product status with Tape & Reel packaging. All electrical specifications, operating temperature range, and RoHS3 compliance are identical to the MMBT3906T-13. Automotive grade and AEC-Q101 qualification status are not specified for this part; however, electrical parameter equivalence is complete.

For applications requiring confirmed automotive qualification and AEC-Q101 certification, MMBT3906T-7-F is the recommended selection. For general-purpose applications where automotive qualification is not a design requirement, MMBT3906T-TP provides equivalent electrical performance with broader availability.

Frequently Asked Questions (FAQ)

Q: Can MMBT3906T-7-F be used as a direct replacement for MMBT3906T-13 in automotive applications?

A: Yes. The MMBT3906T-7-F meets all electrical specifications, maintains AEC-Q101 automotive qualification, and is ROHS3 compliant. Both parts are manufactured by Diodes Incorporated and share identical electrical parameters. The primary difference is product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. unspecified).

Q: What is the difference between MMBT3906T-7-F and MMBT3906T-TP?

A: Both parts are electrical equivalents with identical transistor specifications. The MMBT3906T-7-F is manufactured by Diodes Incorporated and carries AEC-Q101 automotive qualification. The MMBT3906T-TP is manufactured by Micro Commercial Co and does not specify automotive grade or AEC-Q101 qualification. Both are supplied in Tape & Reel packaging and are ROHS3 compliant.

Q: Are there any package or pinout differences between these substitute parts?

A: No. All three parts use the SOT-523 surface mount package with identical pinout and mechanical dimensions. They are mechanically interchangeable at the board level.

Q: Why is the MMBT3906T-13 listed as Obsolete?

A: The MMBT3906T-13 is classified as Obsolete by the manufacturer. Active equivalent parts (MMBT3906T-7-F and MMBT3906T-TP) are available to support continued production and design requirements.

Q: Can I use MMBT3906T-TP in place of MMBT3906T-13 if automotive qualification is required?

A: The MMBT3906T-TP does not specify automotive grade or AEC-Q101 qualification in the provided data. For applications with automotive qualification requirements, MMBT3906T-7-F is the appropriate selection.

Q: Are all three parts RoHS3 compliant?

A: Yes. MMBT3906T-13, MMBT3906T-7-F, and MMBT3906T-TP are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the base product number for these transistors?

A: The base product number is MMBT3906. The suffix designations (-13, -7-F, -TP) indicate specific manufacturer variants and packaging configurations.
