2SB0792ASL Equivalent & Substitute Parts

Part Overview

The 2SB0792ASL is a PNP bipolar junction transistor manufactured by Panasonic Electronic Components, designed for surface mount applications in the Mini3-G1 package. This component operates at a maximum collector voltage of 185 V with a collector current rating of 50 mA and a maximum power dissipation of 200 mW. The device is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SB0792ASL is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Transistor polarity must remain PNP
• Collector-emitter breakdown voltage must equal or exceed 185 V
• Maximum collector current must equal or exceed 50 mA
• Maximum power dissipation must equal or exceed 200 mW
• Operating temperature range must accommodate 150°C maximum junction temperature

Mechanical Compatibility Criteria:

• Package type must be SOT-23-3 (TO-236-3, SC-59)
• Mounting type must be surface mount
• Pin configuration must be compatible with Mini3-G1 footprint

The FMMT596TA from Diodes Incorporated satisfies all substitution criteria, providing enhanced electrical performance characteristics while maintaining mechanical compatibility with the original 2SB0792ASL footprint.

Parameter Comparison

Engineering Selection Recommendations

The FMMT596TA is a direct functional substitute for the obsolete 2SB0792ASL. The substitute part is manufactured by Diodes Incorporated and maintains active product status, ensuring long-term availability and supply chain continuity.

Compliance and Certification:

• FMMT596TA is RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards
• Both parts share identical ECCN (EAR99) and HTSUS (8541.21.0075) classifications
• Moisture sensitivity level remains unchanged at MSL 1 (Unlimited)

Performance Advantages: The FMMT596TA provides enhanced electrical performance relative to the 2SB0792ASL:

• Collector current capacity increased from 50 mA to 300 mA
• Collector-emitter breakdown voltage increased from 185 V to 200 V
• Power dissipation capability increased from 200 mW to 500 mW
• Vce saturation reduced to 350 mV, improving switching efficiency

Performance Trade-off: Transition frequency is reduced from 200 MHz to 150 MHz in the substitute part. This parameter must be evaluated against specific circuit frequency requirements.

Frequently Asked Questions (FAQ)

Q: Can the FMMT596TA directly replace the 2SB0792ASL in existing designs?

A: Yes. The FMMT596TA is mechanically and electrically compatible with the 2SB0792ASL. Both components use the SOT-23-3 package with identical pinout configuration. The substitute part meets or exceeds all critical electrical parameters of the original component.

Q: What are the key differences between these two parts?

A: The primary differences are collector current capacity (50 mA vs. 300 mA), power dissipation (200 mW vs. 500 mW), and transition frequency (200 MHz vs. 150 MHz). The FMMT596TA provides higher current and power handling capability, while the 2SB0792ASL operates at higher frequency. Collector-emitter breakdown voltage is slightly higher in the substitute (200 V vs. 185 V).

Q: Is the FMMT596TA available in the same packaging as the 2SB0792ASL?

A: Yes. Both parts use the SOT-23-3 package (also designated TO-236-3 or SC-59). The FMMT596TA is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly.

Q: What is the impact of the reduced transition frequency in the FMMT596TA?

A: The transition frequency reduction from 200 MHz to 150 MHz affects high-frequency switching performance. For applications operating below 150 MHz, this parameter has no practical impact. Applications requiring operation above 150 MHz must evaluate whether the reduced frequency is acceptable for the specific circuit function.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts share identical ECCN and HTSUS classifications. The FMMT596TA is RoHS3 compliant and REACH unaffected, meeting current environmental standards. Both parts have unlimited moisture sensitivity level (MSL 1).

Q: What is the current availability status of each part?

A: The 2SB0792ASL is obsolete with 840 pieces in stock. The FMMT596TA is an active product with 1846 pieces in stock, providing superior long-term supply chain availability.
