AB01BWS

Overview

The AB01BWS is a general-purpose silicon rectifier diode manufactured by Sanken Electric USA Inc. It features an 800V maximum DC reverse voltage rating and supports a 500mA average forward current. The device utilizes a through-hole axial package design suitable for standard PCB mounting. Key electrical characteristics include a forward voltage of 1.2V at 1A and a reverse leakage current of 5µA at 800V. It operates within a junction temperature range of -40°C to 150°C and exhibits standard recovery speed greater than 500ns.

Feature Summary

• High voltage blocking capability for robust circuit protection
• Standard axial leaded package for reliable through-hole integration
• Wide operating temperature range for diverse environmental conditions

Applications

• General purpose rectification in power supplies
• Protection circuits requiring high reverse voltage tolerance
• Industrial control systems with standard switching requirements

Procurement Notes

Verify the specific suffix 'WS' against the manufacturer's official datasheet to confirm RoHS compliance status and exact pinout configuration. Ensure the ordering quantity aligns with distributor availability, as stock levels fluctuate. Cross-reference the part number with authorized Sanken distributors to guarantee authenticity and traceability. Confirm that the axial package dimensions match your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when a standard recovery diode with 800V blocking capability is required for through-hole applications. The 500mA current rating suits low-to-medium power rectification tasks. Consider the 1.2V forward voltage drop for efficiency calculations in low-voltage secondary circuits. The wide temperature range makes it suitable for industrial environments where thermal stability is critical for long-term reliability.

Part Context

This part belongs to Sanken's general-purpose diode lineup, designed for broad electronic applications. It complements other axial diodes in the series, offering a balance of voltage rating and current handling. The product line focuses on reliability and cost-effectiveness for standard rectification needs in consumer and industrial electronics.

Replacement Considerations

Direct substitutes must match the 800V reverse voltage and 500mA forward current ratings. Verify that any replacement diode maintains the same axial package style and similar forward voltage characteristics to ensure circuit compatibility without redesign.
