1N4562RB

Single Zener Diodes Overview

The Microchip Technology 1N4562RB is a high-power Zener diode designed for robust voltage regulation applications. It features a nominal Zener voltage of 13 V with a tolerance of ±5%. The device supports a maximum power dissipation of 50 W and utilizes a DO-201AB (DO-15) axial leaded package suitable for through-hole mounting. Key electrical characteristics include a maximum Zener impedance of 0.12 Ohms, a reverse leakage current of 20 µA at 1 V, and a forward voltage drop of 1.5 V at 10 A. It operates within a junction temperature range of -65°C to 175°C.

Single Zener Diodes Procurement Notes

Verify the specific suffix RB against official datasheets to confirm it denotes the standard commercial version rather than a military or space-grade variant. Ensure the ordering documentation explicitly references the 1N4562B series specifications. Confirm that the component meets the required RoHS status if applicable to your manufacturing process. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity.

Single Zener Diodes Selection Notes

Select this component when a 13 V regulation point is required with substantial power handling capabilities. The 50 W rating allows for use in applications where standard small-signal diodes would fail due to thermal stress. Consider the axial leaded package for easy integration into PCBs requiring mechanical stability. Evaluate the ±5% tolerance against circuit sensitivity requirements before finalizing the design.

Single Zener Diodes Part Context

This component belongs to the 1N4557B through 1N4564B series of 50 Watt Zener diodes manufactured by Microchip Technology. These devices are JEDEC registered and provide a wide range of voltage values from 3.9 V to 200 V. The series is known for its rugged construction and suitability for demanding industrial environments where reliability under high power conditions is critical.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other 50 W Zener diodes with a 13 V nominal voltage and similar impedance ratings. Verify that any replacement matches the DO-201AB package dimensions and thermal characteristics. Ensure the alternative component offers comparable reverse leakage and forward voltage performance.
