Z4DGP406L-HF

Overview

The Z4DGP406L-HF is a single-phase bridge rectifier manufactured by Comchip Technology, designed for surface-mount applications in the Z4-D package. It features a repetitive peak reverse voltage of 600 V and an average forward current rating of 4.0 A. The device supports a peak forward surge current of 150 A under standard test conditions. Electrical characteristics include a maximum forward voltage of 0.95 V at 4.0 A and a maximum repetitive peak reverse current of 5 µA at 25°C. Thermal performance is defined by a junction-to-ambient thermal resistance of 35 °C/W and a junction-to-lead resistance of 15 °C/W. The component operates within a temperature range of -55°C to +175°C.

Feature Summary

• Low forward voltage design intended to minimize power loss and enhance conversion efficiency.
• Constructed with glass passivated rectifier chips and an internal GPRC structure.
• Utilizes a leadless chip form factor to prevent lead damage during assembly.
• Encapsulated in a plastic package rated for UL flammability classification 94V-0.

Applications

• General-purpose AC to DC rectification in compact electronic circuits.
• Power supply modules requiring low-profile surface-mount components.
• High-efficiency rectification stages in consumer electronics.
• Industrial control systems operating within specified thermal limits.

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm compliance with halogen-free requirements and RoHS standards. Ensure that the procurement channel provides valid traceability data matching the original production batch. Confirm that the delivered packaging adheres to the specified reel taping dimensions and moisture sensitivity levels to maintain component integrity prior to soldering.

Selection Notes

Select this component when a 600 V reverse voltage rating and 4.0 A continuous current capacity are required for surface-mount designs. Consider the Z4-D package dimensions for PCB layout constraints and verify that the thermal management strategy accommodates the specified junction-to-ambient thermal resistance. Evaluate the forward voltage drop characteristics against system efficiency targets to ensure optimal power dissipation performance.

Part Context

This part belongs to the Z4DGP4 Series of Low VF SMD Bridge Rectifiers produced by Comchip Technology. The series encompasses variants with different voltage ratings, including 800 V and 1000 V options, all sharing the same 4.0 A current capability and Z4-D surface-mount package. The 'L' designation indicates a low forward voltage characteristic, while the 'HF' suffix denotes halogen-free manufacturing.

Replacement Considerations

Direct substitutes within the same series include Z4DGP408L-HF (800 V) and Z4DGP410L-HF (1000 V), provided the circuit voltage does not exceed their respective ratings. Cross-manufacturer replacements must match the 4.0 A current, 600 V reverse voltage, and Z4-D package footprint.
