Overview
The CD1607-B120 is a Schottky Barrier Rectifier Chip Diode manufactured by Bourns Inc. It utilizes the Mini-SMA (1607) surface-mount package and provides an average forward current of 1 A with a repetitive peak reverse voltage rating of 20 V. The device features a maximum forward voltage drop of 0.5 V at 1 A and a typical junction capacitance of 110 pF measured at 1 MHz. It operates within a junction temperature range of -55 °C to +125 °C and supports a surge peak forward current of 30 A under single half-wave sine-wave conditions.
Feature Summary
- Very low forward voltage drop for efficient rectification
- Low profile Mini-SMA package design for PCB real estate savings
- Flat configuration prevents roll-away during automated assembly
- Lead-free and RoHS compliant construction
Applications
- Cellular phones
- PDAs
- Desktop PCs and notebooks
- Digital cameras
- MP3 players
Procurement Notes
Verify that the specific order matches the required electrical parameters, specifically the 20 V reverse voltage and 1 A forward current ratings. Confirm the package type is the Mini-SMA (1607) format. Ensure compliance requirements such as lead-free terminations are met if specified. Always validate actual device performance in the final application circuit against datasheet limits.
Selection Notes
Select this component when space-constrained designs require a 1 A Schottky rectifier with a 20 V blocking capability. The Mini-SMA footprint offers significant size reduction compared to standard packages. Consider the 0.5 V forward voltage drop for power loss calculations. Verify thermal management needs based on the 20 °C/W junction-to-lead thermal resistance rating.
Part Context
This part belongs to the Bourns CD1607 series of Schottky Barrier Rectifiers designed for portable electronics. The series includes variants with different reverse voltage ratings (20 V and 40 V) and forward voltage options (standard and low Vf). All models share the same compact Mini-SMA package and JEDEC conforming standards for automated handling.
Replacement Considerations
Compatible substitutes include other 1 A, 20 V Schottky diodes in the Mini-SMA (1607) package from manufacturers such as Vishay or Diodes Inc. Verify pinout polarity, forward voltage characteristics, and thermal resistance before substitution.
FAQ
What is the typical junction capacitance of the CD1607-B120?
The typical junction capacitance is 110 pF, measured at 1 MHz with an applied reverse voltage of 4.0 V DC.
How does the 'L' suffix affect the CD1607-B120 specifications?
The 'L' suffix indicates a Low Forward Voltage variant. For example, the CD1607-B120L has a maximum forward voltage of 0.38 V, compared to 0.5 V for the standard CD1607-B120.
