FMB-26

Diode Arrays Overview

The FMB-26 is a silicon Schottky barrier diode designed for high-frequency rectification applications. It features a peak reverse voltage of 60V and an average forward current rating of 4.0A at a case temperature of 128°C or lower. The device supports a peak surge forward current of 40A for 10 milliseconds. Key electrical characteristics include a maximum forward voltage drop of 0.58V at 1.6A and 0.62V at 2.0A. The junction temperature range spans from -40°C to +150°C, with a thermal resistance between junction and case of 4.0°C/W.

Diode Arrays Procurement Notes

Verify the component status before procurement as the datasheet explicitly states it is not recommended for new designs. Confirm that the specific lot number markings align with your manufacturing requirements. Ensure that the absolute maximum ratings, particularly the case temperature limit of 128°C for full current load, are strictly adhered to in the final system design to prevent reliability issues.

Diode Arrays Selection Notes

Select this component only if the application specifically requires a 60V Schottky diode and can accommodate the 'not recommended for new designs' status. Evaluate whether the 4.0A average forward current and 40A surge capability meet the circuit demands. Consider the thermal resistance of 4.0°C/W when designing the heat dissipation strategy, ensuring the case temperature remains within safe operating limits during continuous operation.
