Overview
The Nexperia BAT854CW is a planar Schottky barrier dual diode featuring an integrated guard ring for stress protection. It is encapsulated in the SOT323 (SC-70) surface-mounted device plastic package with three leads. The device supports a reverse voltage of 40 V and a forward current of 200 mA per diode. Key electrical parameters include a maximum forward voltage of 420 mV at 30 mA, a maximum reverse current of 0.5 µA at 25 V, and a diode capacitance of 20 pF at 1 MHz. The junction temperature rating reaches 150 °C.
Feature Summary
- Very low forward voltage
- Very low reverse current
- Guard ring protected
- Very small SMD plastic package
Applications
- Ultra high-speed switching
- Voltage clamping
- Protection circuits
- Blocking diodes
- Low power consumption applications
Procurement Notes
Verify the specific ordering suffix to confirm packaging details such as reel or cut tape quantities. Confirm that the non-automotive qualified status aligns with your design requirements, as automotive versions require different part numbers. Ensure the SC-70 footprint matches your PCB layout guidelines before finalizing procurement orders.
Selection Notes
Select this component when a compact dual Schottky configuration is required for signal processing or rectification. The low forward voltage makes it suitable for low-power applications. Verify that the 40 V reverse voltage rating exceeds the peak inverse voltage in your circuit. Consider the thermal resistance characteristics if operating near ambient temperature limits.
Part Context
This component belongs to the BAT85 series of Schottky barrier diodes manufactured by Nexperia. It utilizes planar technology within a standard SOT323 package. The product data sheet revision history indicates a transition from automotive qualification to non-automotive status in recent updates. This distinguishes it from the -Q variants intended for automotive environments.
