BAT42-TAP

Single Diodes Overview

The BAT42-TAP is a small signal Schottky diode manufactured by Vishay Semiconductors, housed in the DO-35 (DO-204AH) axial leaded package. It features a single circuit configuration with a repetitive peak reverse voltage of 30 V and a forward continuous current rating of 200 mA. The device exhibits a low forward voltage drop, typically 1000 mV at 200 mA, and a maximum leakage current of 0.5 μA at 25 V. Electrical characteristics include a reverse breakdown voltage of 30 V, a surge forward current capacity of 4 A, and a power dissipation limit of 200 mW. The component operates within an ambient temperature range of -65 °C to +125 °C.

Single Diodes Feature Summary

• Features very low turn-on voltage for efficient signal processing
• Includes integrated fast guard ring protection against excessive voltage such as electrostatic discharges
• Designed for general purpose applications requiring reliable switching

Single Diodes Applications

• General purpose rectification circuits
• Protection against electrostatic discharge events
• High frequency signal detection due to fast recovery characteristics

Single Diodes Procurement Notes

Verify the specific ordering suffix TAP indicates ammunition tape packaging when sourcing components. Confirm that the manufacturer designation aligns with Vishay Semiconductors rather than other distributors using similar part numbers. Ensure compliance with RoHS requirements by checking the detailed product specification sheet provided by the supplier. Validate that the DO-35 package dimensions match your board layout constraints before finalizing procurement orders.

Single Diodes Selection Notes

Select this component for through-hole designs requiring robust ESD protection alongside standard Schottky rectification. The DO-35 package offers mechanical stability compared to surface mount alternatives. Consider the thermal resistance of 300 K/W when designing heat dissipation strategies. Verify that the 30 V reverse voltage rating meets the peak inverse voltage requirements of the target application circuit.

Single Diodes Part Context

This component belongs to the BAT42/BAT43 series of small signal Schottky diodes from Vishay. The BAT42 variant specifically targets applications needing slightly higher forward voltage characteristics compared to the BAT43. The TAP suffix denotes availability in ammo pack packaging, distinct from the TR suffix used for reel packaging. This series represents a standard solution for low-voltage signal handling in consumer and industrial electronics.

Single Diodes Replacement Considerations

BAT43 serves as a functional alternative within the same Vishay family offering lower forward voltage characteristics.
