NTSB30U100CT-1G

Single Diodes Overview

The NTSB30U100CT-1G is a dual common cathode Schottky rectifier from onsemi, housed in an I2PAK (TO-262) surface-mount package. It features a repetitive reverse voltage of 100 V and an average forward current of 30 A per anode. The device exhibits a maximum forward voltage of 900 mV at rated current and supports a non-repetitive peak forward surge current of 350 A. Designed for high-efficiency power conversion, it offers low forward voltage drop and fast switching characteristics suitable for DC-DC converters.

Single Diodes Feature Summary

• Dual common cathode configuration for efficient bridge or center-tapped applications
• Low forward voltage drop to minimize conduction losses and heat generation
• Fast switching capability with typical reverse recovery time under 50 ns
• Robust thermal performance via the I2PAK leaded package design

Single Diodes Applications

• High-frequency DC-DC converter output rectification
• Free-wheeling diodes in synchronous buck regulators
• Power supply input protection circuits
• General purpose rectification in industrial power systems

Single Diodes Procurement Notes

Verify component authenticity through authorized onsemi distributors or certified partners. Confirm RoHS compliance and material composition declarations prior to integration. Check for obsolescence status as lifecycle changes may affect long-term availability. Ensure storage conditions adhere to manufacturer guidelines to maintain junction integrity and solderability before assembly.

Single Diodes Selection Notes

Select this component when a dual Schottky solution is required in an I2PAK footprint. Compare forward voltage specifications against system efficiency targets. Evaluate thermal resistance values relative to the available PCB copper area for adequate heat dissipation. Ensure the 100 V rating exceeds the maximum circuit voltage including transients. Verify that the 30 A continuous current rating accommodates peak load requirements without exceeding junction temperature limits.

Single Diodes Part Context

This part belongs to onsemi’s NTSB series of ultra-fast Schottky rectifiers. It serves as a higher-current alternative to smaller packages like TO-220AC while offering better thermal handling than standard SMD options. The I2PAK package provides a balance between mounting simplicity and power handling capacity for medium-power applications.

Single Diodes Replacement Considerations

Direct substitutes include the MBRB41H100CT-1G, which shares similar electrical ratings and package type but offers a 40 A current rating. Verify pinout compatibility and thermal characteristics when cross-referencing other dual Schottky devices from different manufacturers.
