Overview
The BAV20W-E3-18 is a silicon epitaxial planar switching diode from Vishay Semiconductors, housed in an SOD-123 surface-mount package. It features a continuous reverse voltage of 150 V and a repetitive peak reverse voltage of 200 V. The device supports a DC forward current of 250 mA and an average rectified current of 200 mA. Electrical characteristics include a maximum forward voltage of 1.25 V at 200 mA, a leakage current of 100 nA at 150 V, and a reverse recovery time of 50 ns. Thermal resistance junction-to-ambient air is 375 °C/W, with a maximum junction temperature of 150 °C.
Feature Summary
- Silicon epitaxial planar construction for high reliability
- High voltage capability suitable for general-purpose applications
- RoHS-compliant commercial grade availability
Applications
- General-purpose switching circuits
- High-voltage signal processing
- Fast switching logic interfaces
Procurement Notes
Verify the specific ordering suffix to confirm packaging format; suffix -18 indicates tape and reel packaging on a 13-inch reel. Confirm RoHS compliance status based on the base part number designation. Ensure the application environment remains within the specified operating temperature range of -55 °C to +150 °C. Validate thermal management requirements against the 375 °C/W thermal resistance limit. Check for AEC-Q101 qualification if automotive-grade reliability is required, noting that HE3 variants offer this qualification.
Selection Notes
Select the BAV20W-E3-18 when a 150 V continuous reverse voltage rating is required for small-signal switching. Compare against BAV19W (100 V) or BAV21W (200 V) variants to match specific circuit voltage constraints. Consider the SOD-123 package dimensions for PCB layout compatibility. Evaluate the 50 ns reverse recovery time against switching speed requirements. Verify power dissipation limits under expected ambient temperature conditions.
Part Context
This component belongs to the BAV19W/BAV20W/BAV21W series of small-signal switching diodes. All models share identical physical packages and electrical characteristics except for their reverse voltage ratings. The series utilizes silicon epitaxial planar technology designed for general-purpose applications. Packaging options include cut tape and reel formats depending on the ordering suffix.
Replacement Considerations
Direct functional substitutes within the same family include BAV19W-E3-18 and BAV21W-E3-18, differing only in reverse voltage ratings. Cross-manufacturer replacements must match the SOD-123 footprint, 150 V reverse voltage, and 250 mA forward current specifications.
