IPS0151 Equivalent & Substitute Parts

Part Overview

The IPS0151 is a Power Switch/Driver N-Channel 1:1 low-side switch rated for 4.3A maximum output current in a TO-220AB package, manufactured by Infineon Technologies. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and production continuity. The part operates across a -40°C to 150°C temperature range with integrated current limiting and over-temperature fault protection.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IPS0151 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Output Configuration: Low Side
• Output Type: N-Channel
• Ratio - Input:Output: 1:1
• Interface: On/Off
• Input Type: Non-Inverting
• Package / Case: TO-220-3
• Mounting Type: Through Hole

Performance Envelope Criteria:

• Voltage - Load: Must equal or exceed 35V maximum
• Current - Output (Max): Must equal or exceed 4.3A
• Fault Protection: Must include at minimum Current Limiting and Over Temperature protection

The substitute parts listed below meet all primary compatibility criteria and operate within or exceed the performance envelope of the IPS0151. All substitutes are active products with current manufacturing status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

VNP20N07-E is the direct functional equivalent for applications requiring the IPS0151's performance envelope. This STMicroelectronics OMNIFET™/VIPower™ series component maintains identical electrical topology while providing 14A output capability, exceeding the IPS0151's 4.3A rating. The 55V load voltage rating provides additional design margin over the original 35V specification. Enhanced fault protection includes over-voltage detection in addition to current limiting and over-temperature monitoring. ROHS3 compliance and active product status ensure long-term supply availability and regulatory alignment.

VNP35N07-E is suitable for applications where higher current capacity (25A) is beneficial or where design headroom is required. This part operates within the same electrical framework as the IPS0151 but is optimized for higher-power switching applications. The increased Rds On specification reflects the higher current rating. ROHS3 compliance and extensive inventory (364,522 units) support high-volume production requirements.

Both substitutes are pin-compatible within the TO-220-3 package and maintain the same interface protocol (On/Off, Non-Inverting). Selection between VNP20N07-E and VNP35N07-E depends on application current requirements and thermal design considerations.

Frequently Asked Questions (FAQ)

Q: Can VNP20N07-E and VNP35N07-E be used interchangeably with IPS0151?

A: Both parts are functionally equivalent substitutes for the IPS0151 within the specified electrical and mechanical parameters. They share identical package geometry (TO-220-3), interface protocol (On/Off, Non-Inverting), and output configuration (Low Side N-Channel 1:1). Selection between them depends on application current requirements.

Q: What is the significance of the higher voltage rating (55V vs. 35V) in the substitute parts?

A: The increased maximum load voltage rating in VNP20N07-E and VNP35N07-E provides additional design margin and allows operation in higher-voltage applications. Existing designs operating at or below 35V remain fully compatible with either substitute.

Q: Are there thermal considerations when substituting these parts?

A: The Rds On specification affects power dissipation. VNP20N07-E (50mOhm max) dissipates less power than VNP35N07-E (280mOhm max) at equivalent current levels. Thermal design should account for the selected part's on-resistance characteristics.

Q: What compliance advantages do the substitute parts offer?

A: Both VNP20N07-E and VNP35N07-E are ROHS3 compliant, whereas the IPS0151 is RoHS non-compliant. Both substitutes are active products with current manufacturing status, ensuring long-term availability and regulatory alignment with modern procurement standards.

Q: Is the TO-220-3 package identical across all three parts?

A: Yes. All three parts use the TO-220-3 package with identical pin configuration and mechanical footprint, enabling direct board-level substitution without layout modifications.

Q: How do the fault protection features compare?

A: The IPS0151 includes Current Limiting (Fixed) and Over Temperature protection. Both substitute parts include these protections plus Over Voltage detection, providing enhanced system reliability.
