Overview
The MCC 1N4936-AP is a fast recovery rectifier diode from the 1N4933 through 1N4937 series, housed in a DO-41 axial leaded package. It features a maximum repetitive peak reverse voltage of 400V and an average forward current rating of 1.0A at 55°C. The device exhibits a maximum instantaneous forward voltage of 1.3V at 1.0A and a typical junction capacitance of 15pF. Electrical characteristics include a maximum reverse recovery time of 200ns and a peak forward surge current capability of 30A for half-sine pulses.
Feature Summary
- Glass passivated junction construction designed for high reliability under demanding conditions
- Fast switching performance optimized for high efficiency applications
- Low leakage current characteristics across specified temperature ranges
- High forward surge current capability to withstand transient loads
Applications
- General purpose rectification in power supply circuits
- Free-wheeling diodes in inductive load switching
- Polarity protection in electronic systems
Procurement Notes
Verify the specific ordering suffix to confirm packaging format, as the AP designation indicates Ammo packing containing 5000 units per box. Confirm RoHS compliance status by checking for the P suffix or relevant documentation notes. Ensure procurement channels are authorized distributors to guarantee genuine parts with full traceability and adherence to MCC quality standards.
Selection Notes
Select this component when a 400V blocking voltage and 1A continuous current rating are required in a standard axial package. Consider the 200ns reverse recovery time for general fast recovery needs rather than ultra-fast switching applications. Evaluate thermal derating requirements if operating ambient temperatures exceed 55°C to maintain the 1.0A current rating safely.
Part Context
This part belongs to the 1N4933 through 1N4937 family of 1 Amp glass passivated fast recovery rectifiers manufactured by Micro Commercial Components. The series covers voltage ratings from 50V to 600V, providing standardized options for various reverse voltage requirements while maintaining consistent physical dimensions and electrical characteristics across the lineup.
Replacement Considerations
Cross-reference with other manufacturers' 1N4936 equivalents ensuring identical DO-41 packaging and matching electrical parameters such as 400V VRRM and 1.0A IF(AV). Verify that substitute components meet the same reverse recovery time and forward voltage specifications for circuit compatibility.
