BTS6123B Equivalent & Substitute Parts

Part Overview

The BTS6123B is a Power Switch/Driver IC from Infineon Technologies' PROFET® series, designed for high-side N-channel switching applications. It provides 1:1 input-to-output ratio switching with 9A maximum output current, integrated current limiting, open load detection, and over-temperature protection. The device is rated for load voltages between 5.5V and 38V and operates across the industrial temperature range of -40°C to 150°C.

The BTS6123B has been discontinued at DiGi Electronics. Identifying equivalent substitute parts ensures design continuity and maintains supply chain reliability for applications requiring this switching topology and performance envelope.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BTS6123B is determined by the following critical parameters:

• Output Current Rating: Minimum 9A to maintain design margin
• Voltage Range: Load voltage capability of 5.5V ~ 38V
• Output Configuration: High-side N-channel switching with 1:1 ratio
• Fault Protection Features: Current limiting, open load detection, over-temperature, and over-voltage protection
• Operating Temperature Range: -40°C ~ 150°C (TJ)
• Package Compatibility: TO-263-8 / D2PAK form factor for direct PCB replacement
• Manufacturer Series: PROFET® series for functional equivalence

The BTS500801TMAATMA1 meets all substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

The BTS500801TMAATMA1 is the direct parametric equivalent for the discontinued BTS6123B. Both devices share identical electrical specifications across all critical switching parameters, fault protection features, and thermal operating range.

The BTS500801TMAATMA1 offers two additional advantages:

• Product Status: Active availability ensures long-term supply chain continuity
• Regulatory Compliance: ROHS3 compliant, whereas the BTS6123B is RoHS non-compliant

The BTS500801TMAATMA1 provides improved performance characteristics with 0.5A higher maximum output current (9.5A vs. 9A) and lower on-resistance (7mOhm vs. 8mOhm), delivering enhanced efficiency and thermal performance in the same package footprint.

Frequently Asked Questions (FAQ)

Q: Can the BTS500801TMAATMA1 directly replace the BTS6123B on existing PCBs?

A: Yes. Both devices use identical TO-263-8 / D2PAK packaging with the same pinout and lead configuration. No PCB modifications are required for direct substitution.

Q: What are the key differences between these parts?

A: The BTS500801TMAATMA1 has a higher maximum output current rating (9.5A vs. 9A) and lower on-resistance (7mOhm vs. 8mOhm). The BTS500801TMAATMA1 is ROHS3 compliant and maintains active product status, while the BTS6123B is discontinued.

Q: Are the electrical characteristics compatible for my application?

A: Both parts operate within the same voltage range (5.5V ~ 38V), temperature range (-40°C ~ 150°C), and provide identical fault protection features. The BTS500801TMAATMA1's higher current rating and lower on-resistance make it suitable for all applications designed for the BTS6123B.

Q: What packaging options are available for the BTS500801TMAATMA1?

A: The BTS500801TMAATMA1 is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. The device maintains the same TO-263-8 / D2PAK form factor as the original BTS6123B.

Q: Are there any design considerations when switching from BTS6123B to BTS500801TMAATMA1?

A: No design changes are necessary. The lower on-resistance of the BTS500801TMAATMA1 may result in reduced power dissipation and improved thermal performance, which are beneficial characteristics for existing designs.
