BA283-TR

Overview

The BA283-TR is a single switching diode manufactured by Vishay General Semiconductor - Diodes Division. It is designed for through-hole installation in the DO-35 axial leaded package. The device features a maximum average forward output current of 100 mA and a maximum repetitive reverse voltage of 35 V. Electrical characteristics include a maximum forward voltage drop of 1 V, a maximum series resistance of 0.9 Ω at 10 mA, and a maximum diode capacitance of 1.2 pF. The component supports a maximum operating junction temperature of +150 °C.

Feature Summary

• Single diode configuration optimized for general-purpose switching applications
• Axial leaded DO-35 package suitable for through-hole mounting processes
• Low capacitance design supporting high-speed signal handling

Applications

• General purpose signal switching circuits
• Protection against reverse polarity in low-current paths
• Clamping applications within low-voltage logic interfaces

Procurement Notes

Verify the specific ordering suffix to confirm tape-and-reel packaging requirements. Confirm RoHS compliance status via the manufacturer datasheet. Ensure the DO-35 package dimensions match the target PCB footprint. Validate that the 35 V reverse voltage rating meets the circuit's peak inverse voltage demands. Check for any AEC-Q qualifications if automotive reliability is required.

Selection Notes

Select this component when a low-capacitance switching diode is needed for currents up to 100 mA. The DO-35 package is appropriate for standard through-hole assembly lines. Consider the 35 V reverse voltage limit for low-voltage signal lines. Evaluate the 1.2 pF capacitance for high-frequency signal integrity. Compare thermal performance against the +150 °C junction temperature limit.

Part Context

The BA283-TR belongs to Vishay's range of small-signal switching diodes. It utilizes the standard DO-35 glass passivated junction technology. This family provides reliable performance for discrete signal processing tasks. The part is distinct from rectifier or power diode categories due to its low current rating.

Replacement Considerations

Cross-reference with other DO-35 switching diodes offering similar 35 V reverse voltage and 100 mA forward current ratings. Verify pinout compatibility and package dimensional tolerances before substitution. Ensure equivalent capacitance and forward voltage specifications are met.
