HER104S-AP

Single Diodes Overview

The MCC HER104S-AP is a high-efficiency silicon rectifier from the HER101S through HER108S series, designed for single-phase half-wave or full-wave bridge configurations. It features a maximum average forward current of 1.0 A at an ambient temperature of 55°C and supports peak forward surge currents up to 30 A under JEDEC testing conditions. The device provides a maximum repetitive peak reverse voltage of 300 V with a corresponding maximum RMS voltage of 210 V. Electrical characteristics include a maximum instantaneous forward voltage of 1.0 V at 1.0 A and a typical junction capacitance of 20 pF measured at 1.0 MHz.

Single Diodes Feature Summary

• Utilizes fast recovery technology to achieve low forward voltage drop and high efficiency in power conversion applications.
• Encapsulated in epoxy that meets UL 94 V-0 flammability ratings for enhanced safety compliance.
• Engineered for high reliability with robust surge current capability suitable for resistive and inductive loads.

Single Diodes Applications

• General-purpose rectification in AC/DC power supply circuits
• Bridge rectifier configurations for consumer electronics
• Battery charging systems requiring efficient DC conversion

Single Diodes Procurement Notes

Verify the specific ordering suffix against official Micro Commercial Components documentation to ensure correct packaging and material specifications. Confirm that the component selection aligns with authorized distributor channels to guarantee genuine parts with full traceability. Review the manufacturer's life support policy to ensure the application does not require critical system certification without express written approval.

Single Diodes Selection Notes

Select this component when a 300 V blocking voltage rating is required alongside a 1.0 A continuous current capacity. Ensure the operating environment remains within the specified -55°C to +125°C junction temperature range. Consider derating the forward current by 20% if the circuit involves capacitive loads to maintain operational stability and prevent thermal overstress during peak demand periods.

Single Diodes Part Context

This part belongs to the HER101S through HER108S family of high-efficiency rectifiers manufactured by Micro Commercial Components. The series offers standardized pinout and mechanical dimensions across varying voltage ratings, facilitating design flexibility. The HER104S specifically bridges the gap between lower voltage options like the HER103S and higher voltage variants such as the HER105S.

Single Diodes Replacement Considerations

Direct substitutes within the same voltage class include the HER103S (200V) and HER105S (400V), provided the system voltage margins accommodate the difference. Verify that any replacement maintains the 1.0 A current rating and compatible package type to ensure physical and electrical interchangeability.
