Overview
The AR1PK-M3/84A is a silicon avalanche rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a single diode configuration housed in a surface-mount DO-220AA (SMP) package with two pins. The device supports a maximum repetitive peak reverse voltage of 800 V and an average forward rectified current of 1 A. It operates within a junction temperature range of -55 °C to +175 °C.
Feature Summary
- Incorporates avalanche ruggedness for enhanced reliability under transient conditions
- Utilizes silicon planar technology for robust construction
- Designed for surface-mount assembly in compact electronic circuits
Applications
- High-voltage power supply circuits requiring avalanche capability
- Flyback diode applications in inductive load switching
- General-purpose rectification in industrial equipment
Procurement Notes
Verify the specific suffix /84A against the manufacturer's latest datasheet to confirm packaging details and availability status. Ensure that the selected component matches the required avalanche rating and thermal specifications for the target application environment before finalizing procurement orders.
Selection Notes
Select this component when high-voltage blocking capability combined with avalanche energy handling is required in a small surface-mount footprint. Compare the 800 V rating and 1 A current capacity against circuit demands to ensure adequate margin for peak voltages and continuous currents.
Part Context
This part belongs to Vishay's general-purpose avalanche rectifier series, designed for applications where standard recovery characteristics are sufficient but transient overvoltage resilience is critical. It complements other SMP packaged diodes offering similar voltage ratings with varying recovery speeds or current capacities.
Replacement Considerations
Consult official substitution guides for equivalent avalanche rectifiers in the DO-220AA package with matching 800 V and 1 A ratings. Verify pinout compatibility and thermal performance before implementing any alternative components.
