BTS117 Equivalent & Substitute Parts

Part Overview

The BTS117 is an N-Channel power switch/driver IC manufactured by Infineon Technologies, designed for low-side switching applications with a 1:1 input-to-output ratio. This device operates at a maximum load voltage of 60V with an output current capability of 3.5A and an on-resistance (RDS On) of 80mOhm typical. The BTS117 is packaged in TO-263-3 (D2PAK) surface mount configuration and includes integrated fault protection featuring current limiting, over-temperature, and over-voltage protection.

The BTS117 has reached obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for new production runs and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BTS117 is determined by the following critical parameters:

• Output Configuration & Type: Low-side N-Channel switching topology (1:1 ratio)
• Voltage Rating: Load voltage capability must meet or exceed 60V maximum
• Current Capability: Output current rating must support the application requirement of 3.5A minimum
• Fault Protection: Current limiting, over-temperature, and over-voltage protection required
• Interface Type: On/Off control with non-inverting input
• Thermal Range: Operating temperature range of -40°C to 150°C

The substitute parts VNP20N07-E and VNP35N07-E, both manufactured by STMicroelectronics, meet these core functional requirements. Both devices are low-side N-Channel power switches with 1:1 input-to-output ratio, integrated fault protection, and compatible control interfaces. The VNP20N07-E provides 14A output current capability, while the VNP35N07-E provides 25A, both exceeding the BTS117's 3.5A requirement. Both substitute parts operate at 55V maximum load voltage, which is within the application envelope of the 60V-rated BTS117.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The BTS117 is obsolete, while both VNP20N07-E and VNP35N07-E are active products with confirmed inventory availability. Active product status ensures long-term supply chain reliability and access to technical support.

Compliance Status: Both substitute parts are ROHS3 compliant, meeting modern regulatory requirements. The original BTS117 is RoHS non-compliant, making the substitutes preferable for new designs and applications subject to environmental regulations.

Functional Compatibility: Both substitute parts satisfy the core switching requirements of the BTS117. The VNP20N07-E and VNP35N07-E provide equivalent low-side N-Channel switching topology with identical 1:1 input-to-output ratio and compatible fault protection architecture.

Current Capability: The VNP20N07-E (14A) and VNP35N07-E (25A) both exceed the BTS117's 3.5A output current specification, providing design margin for applications operating at or below the original current requirement.

Voltage Rating: Both substitute parts operate at 55V maximum load voltage. Applications designed for the BTS117's 60V rating must confirm that actual operating voltages remain within the 55V limit of the substitute parts.

Packaging Consideration: The BTS117 uses surface mount TO-263-3 packaging, while both substitute parts use through-hole TO-220-3 packaging. PCB layout modification is required for substitution.

Frequently Asked Questions (FAQ)

Q: Can VNP20N07-E and VNP35N07-E be used interchangeably with the BTS117?

A: Both parts are functionally equivalent as low-side N-Channel power switches with 1:1 control ratio and integrated fault protection. Selection between them depends on application current requirements. The VNP20N07-E supports 14A, while the VNP35N07-E supports 25A. Both exceed the BTS117's 3.5A specification.

Q: What is the primary difference between VNP20N07-E and VNP35N07-E?

A: The primary difference is output current capability. VNP20N07-E provides 14A maximum output current with 50mOhm (Max) RDS On. VNP35N07-E provides 25A maximum output current with 280mOhm (Max) RDS On. Both operate at identical 55V maximum load voltage and share the same control interface and fault protection features.

Q: Are there packaging compatibility issues when substituting the BTS117?

A: Yes. The BTS117 uses surface mount TO-263-3 (D2PAK) packaging, while both substitute parts use through-hole TO-220-3 packaging. PCB redesign is required to accommodate the different package footprint and mounting method.

Q: Do the substitute parts meet the BTS117's voltage specification?

A: The substitute parts operate at 55V maximum load voltage, which is 5V lower than the BTS117's 60V rating. Applications must confirm that actual operating voltages remain within the 55V limit. If the application requires operation above 55V, these substitutes are not suitable.

Q: What are the compliance advantages of the substitute parts?

A: Both VNP20N07-E and VNP35N07-E are ROHS3 compliant and active products. The BTS117 is RoHS non-compliant and obsolete. The substitutes meet current environmental regulations and have confirmed long-term availability.

Q: Are the control interfaces compatible between the BTS117 and substitute parts?

A: Yes. All three parts use identical On/Off control with non-inverting input configuration, ensuring direct control signal compatibility without interface modification.
