IRFBE20PBF – P-Channel Power MOSFET

is a P-Channel Power MOSFET developed by Vishay, designed for high-speed switching applications and efficiency-critical power conversion circuits. With a drain-source voltage rating of -200V, this part supports continuous drain current around -4.3A and features low on-resistance (R_DS(on)) and fast switching capability. Its TO-220 package allows easy thermal management and high current handling with through-hole mounting. This device is widely used in automotive DC-DC converters, reverse polarity protection, H-bridges, and solar inverters.

Being lead-free and RoHS compliant, the IRFBE20PBF is a trusted solution for industrial and high-reliability applications.

Why Choose EstiSource for Sourcing

EstiSource is built for technical buyers and engineering teams that demand accuracy, agility, and assurance. Whether you're designing circuits, sourcing components, or quoting for a global tender, our platform lets you compare, validate, and source electronic parts like IRFBE20PBF with unmatched speed and reliability. With EstiSource, you move from datasheet to delivery without friction — your shadow partner in cost estimation and sourcing.

1. Material Composition

▶

The IRFBE20PBF consists of:

Silicon Die (P-Channel): Fabricated using planar technology with high-voltage doping profile to support -200V operation.
Copper Alloy Leadframe: Offers high thermal conductivity and mechanical strength.
Epoxy Mold Compound: Protects internal elements from moisture, shock, and contamination.
Gold/Aluminum Bond Wires: Ensure reliable electrical interconnection between die and leads.
Lead Plating: Tin or matte tin plating is applied on terminals to enhance solderability and prevent corrosion.
TO-220 Package Material: Molded epoxy with embedded heat spreader tab for external heatsink mounting.

2. Manufacturing Process

▶

Wafer Fabrication: High-voltage P-channel MOS structure is created through ion implantation and precise lithography on silicon wafers.
Die Preparation: Individual dies are cut and electrically tested at wafer level.
Die Attach: Die is bonded onto a metal pad on the leadframe using conductive epoxy.
Wire Bonding: Gold or aluminum wires connect the die pads to leadframe terminals.
Molding: Epoxy encapsulation forms the TO-220 package while exposing the metal tab.
Lead Trimming & Forming: Leads are cut and bent to standard TO-220 geometry.
Plating: Leads are plated with solderable finishes.
Testing & QA: Functional testing, parametric analysis, and burn-in for quality assurance.

3. Challenges & Limitations

▶

P-Channel Limitations

Typically higher R_DS(on) than N-channel counterparts, which can affect efficiency in high-load circuits.

Heat Dissipation

Requires proper heatsinking for continuous operation under high current to avoid thermal runaway.

Component Counterfeiting

As Vishay is a top brand, fake variants exist in grey markets. Reliable sourcing is critical.

Lead Time Fluctuation

Global demand may affect stock availability and delivery timelines, especially for Vishay’s older TO-series components.

4. Costing

▶

Unit Cost (Bulk B2B): ₹45–₹70 per unit depending on quantity and distributor.
Small Batch / Retail: ₹75–₹110 per unit when purchased in lower quantities.

Cost Drivers:

Vishay branding and reliability certification
TO-220 package demand across multiple verticals
Availability from authorized sources in India or abroad

Additional Considerations:

Cost of heatsink, if required
Import duties (if sourcing from overseas vendors)
