Overview
The MCC 1N4934-AP is a single-phase, fast recovery silicon rectifier diode housed in the DO-41 axial leaded package. It provides a maximum repetitive peak reverse voltage of 100V and supports an average forward rectified current of 1.0A at 55°C ambient temperature. The device features a maximum instantaneous forward voltage of 1.3V at 1.0A and a peak forward surge current rating of 30A for half-sine pulses. Electrical characteristics include a maximum reverse recovery time of 200ns and a typical junction capacitance of 15pF measured at 1.0MHz.
Feature Summary
- Fast switching capability with low leakage current
- High surge current handling capacity
- Low cost design suitable for general purpose applications
Applications
- General purpose rectification in power supplies
- Free-wheeling diodes in inductive load circuits
- Polarity protection in electronic systems
Procurement Notes
Verify that the part number suffix matches the required packaging format. The -AP suffix indicates Ammo Box packing containing 5,000 pieces per box. Confirm compliance requirements such as RoHS status and halogen-free availability if needed by checking for additional suffixes like -HF or -P on the official datasheet.
Selection Notes
Select this component when a 100V blocking voltage and 1A continuous current are required in a standard through-hole package. Ensure the operating junction temperature remains within the specified range of -55°C to +150°C. Consider the 200ns reverse recovery time for high-frequency switching applications where faster speeds might be necessary.
Part Context
This device belongs to the 1N4933 through 1N4937 series of fast recovery rectifiers manufactured by Micro Commercial Components. All parts in this series share identical electrical ratings except for the maximum repetitive peak reverse voltage, which varies from 50V to 600V across the lineup. They utilize the same DO-41 plastic molded case and epoxy meeting UL 94 V-0 flammability ratings.
Replacement Considerations
Compatible substitutes include other manufacturers' 1N4934 variants such as Vishay's 1N4934GP-E3/54 or Rectron's 1N4934. Verify that replacement parts maintain the same DO-41 footprint, 100V reverse voltage rating, and 1.0A forward current capability to ensure mechanical and electrical compatibility.
