Key Features
- Single silicon rectifier diode with 1.1 V maximum forward voltage (VF) optimized for efficient AC-to-DC rectification in power supply circuits
- 30 A non-repetitive peak forward current (IFSM) rating handles transient surge currents in unprotected input stages without device failure
- Compact 2-pin SMD package (JESD-30 R-PDSO-F2) with lead-free (HF) JESD-609 e3 rating for RoHS-compliant automated SMT assembly
- General-purpose silicon diode element suits broad rectifier, freewheeling, and blocking applications from consumer electronics to industrial power stages
Applications
The CGRKM4007-HF is used as a general-purpose rectifier in AC-DC power supplies, bridge rectifier circuits, and freewheeling diode applications in relay drivers and motor control boards where a 1.1 V maximum forward voltage drop and 30 A surge capability are required. Its compact SMD footprint makes it well suited for space-constrained adapter and charger PCBs in consumer electronics and industrial equipment. The HF (halogen-free) designation also satisfies environmental compliance requirements in green-certified power supply products.

Frequently Asked Questions
What is the peak reverse voltage and surge current rating of the CGRKM4007-HF rectifier diode?
The CGRKM4007-HF is rated for a maximum non-repetitive peak forward current of 30 A and a forward voltage drop of up to 1.1 V at rated conditions, making it suitable for general-purpose rectification in single-phase AC-DC circuits where brief inrush surges occur at power-on.
How does the SMD package of the CGRKM4007-HF compare to through-hole DO-41 rectifiers for board space savings?
The CGRKM4007-HF uses a 2-pin SMD package (JESD-30 R-PDSO-F2) that occupies significantly less PCB area than a DO-41 through-hole diode, enables automated pick-and-place assembly at standard SMT reflow temperatures of 260°C, and eliminates the need for through-hole drilling in multi-layer boards.
Can the CGRKM4007-HF be used as a freewheeling diode in relay driver circuits?
Yes. With its 1.1 V maximum forward voltage and 30 A non-repetitive peak forward current capability, the CGRKM4007-HF effectively clamps the reverse EMF spike generated when a relay coil de-energizes, protecting the switching transistor or microcontroller GPIO from voltage transients that can exceed 5 V on a 12 V relay bus.
What does the HF suffix in CGRKM4007-HF indicate for environmental compliance?
The HF suffix designates a halogen-free construction, meaning the device contains no brominated or chlorinated flame retardants in its packaging materials. Combined with the JESD-609 e3 lead-free solder finish, the CGRKM4007-HF meets RoHS, REACH, and halogen-free standards required by EU and major OEM green procurement programs.
