Overview
The CBAT54S TR PBFREE is a surface-mount silicon Schottky diode manufactured by Central Semiconductor Corp. It features a dual-in-series configuration within an SOT-23 package. The device supports a continuous reverse voltage of 30 V and a continuous forward current of 200 mA. Peak repetitive forward current is rated at 300 mA, with a surge capability of 600 mA for 10 ms pulses. Power dissipation reaches 350 mW, and the junction temperature range spans from -65 °C to +150 °C. Thermal resistance (junction-to-ambient) is specified at 357 °C/W.
Feature Summary
- Dual in-series Schottky diode configuration
- Low forward voltage drop characteristics
- Fast switching speed with minimal reverse recovery time
- Lead-free plating compliant with RoHS standards
Applications
- High-frequency rectification circuits
- Power supply output rectifiers
- Clamping and protection applications
- DC-DC converter designs
Procurement Notes
Verify that the ordering suffix 'TR' indicates tape-and-reel packaging and 'PBFREE' confirms lead-free compliance. Confirm the specific part number matches the dual-in-series configuration rather than single or common-anode variants. Ensure the supplier provides official datasheets to validate electrical parameters against the manufacturer's specifications before finalizing procurement.
Selection Notes
Select this component when a dual-diode series arrangement is required in a compact SOT-23 footprint. The low forward voltage and fast recovery make it suitable for high-efficiency power conversion. Compare thermal resistance and power dissipation limits against circuit requirements to ensure adequate heat management under continuous load conditions.
Part Context
This component belongs to the CBAT54 series of surface-mount silicon Schottky diodes. The series includes single, common-anode, common-cathode, and in-series configurations. All variants share identical maximum ratings but differ in internal connection topology and marking codes. The CBAT54S specifically utilizes the CL44 marking code to distinguish its series configuration.
Replacement Considerations
Direct substitutes include other manufacturers' BAT54S equivalents in SOT-23 packages. Verify that replacement parts maintain the same 30 V reverse voltage, 200 mA forward current, and dual-in-series pinout compatibility.
FAQ
What is the marking code for the CBAT54S?
The marking code for the CBAT54S is CL44.
What is the peak reverse recovery time?
The peak reverse recovery time is 5.0 ns under specified test conditions.
How does the CBAT54S differ from the CBAT54A?
The CBAT54S is configured as dual diodes in series, whereas the CBAT54A is configured as dual diodes with a common anode.
