BAT854CW,115

Overview

The BAT854CW,115 is a planar Schottky barrier dual diode from Nexperia, encapsulated in the SC-70 (SOT323) surface-mount package. It features an integrated guard ring for stress protection and operates with a maximum reverse voltage of 40 V and a continuous forward current of 200 mA per diode. The device exhibits a typical forward voltage of 420 mV at 30 mA and a low reverse current of 0.5 µA at 25 V. Junction temperature ranges from -65 °C to 150 °C.

Feature Summary

• Planar Schottky barrier construction with integrated guard ring for enhanced stress protection
• Very low forward voltage characteristics suitable for efficient power handling
• Extremely low reverse current minimizing leakage losses
• Compact SC-70 plastic surface-mounted package design

Applications

• Ultra high-speed switching circuits
• Voltage clamping applications
• Protection circuits requiring fast response
• Blocking diodes in signal paths
• Low power consumption applications such as hand-held devices

Procurement Notes

Verify that the specific part number matches the non-automotive qualified version, as indicated by the October 2024 revision history. Confirm package dimensions against the SOT323 outline if precise board space is critical. Ensure thermal resistance limits are respected during PCB layout to maintain junction temperatures within specified operating ranges.

Selection Notes

Select this component when a dual Schottky configuration is required in a minimal footprint. The integrated guard ring provides robustness against electrical stress compared to standard planar designs. Consider the 40 V reverse voltage rating and 200 mA current capacity to ensure adequate margins for the target circuit conditions.

Part Context

This device belongs to the BAT85 series of Schottky barrier diodes manufactured by Nexperia. It shares the same physical package and general performance profile as other variants in the family but is specifically configured as a dual diode with common cathode pinning. The product data sheet defines it as a production-stage component intended for general electronic applications.

Replacement Considerations

For automotive-grade requirements, consider the BAT854CW-Q variant which holds AEC-Q101 qualification. Other single or dual Schottky diodes in the SOT323 package may serve as functional substitutes if pinout compatibility and electrical ratings align with the design specifications.

FAQ

Is the BAT854CW,115 automotive qualified?

No, the standard BAT854CW is not automotive qualified. Customers requiring automotive certification should select the BAT854CW-Q variant.

What is the pin configuration for the BAT854CW?

Pin 1 is Anode 1, Pin 2 is Anode 2, and Pin 3 serves as the Common Cathode for both diodes.

What is the maximum non-repetitive peak forward current?

The maximum non-repetitive peak forward current is 1 A under half-sine wave conditions lasting 8.3 ms.
