1N5262

Single Zener Diodes Overview

The SMC Diode Solutions 1N5262 is a silicon planar Zener voltage regulator diode housed in a DO-35 glass axial leaded package. It provides a nominal Zener voltage of 51 V with a standard tolerance of ±5%. The device is rated for a maximum power dissipation of 500 mW at 25°C ambient temperature. Key electrical characteristics include a maximum reverse leakage current of 100 nA and a Zener impedance of 125 Ohms at the test current of 2.5 mA. It supports a forward current of 200 mA with a forward voltage drop of 1.1 V. The component operates within a junction temperature range from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Utilizes metallurgically bonded double slug construction for hermetic sealing
• Features a glass DO-35 package suitable for high-temperature soldering
• Provides stable voltage regulation across a wide operating temperature range

Single Zener Diodes Applications

• Voltage reference circuits requiring precise regulation
• Overvoltage protection stages in electronic systems
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify the specific manufacturer suffix or lot code when sourcing, as the 1N5262 designation is used by multiple vendors including Microchip, Vishay, and SMC Diode Solutions. Confirm RoHS compliance status and packaging format (reel vs. cut tape) against your assembly requirements. Ensure the supplier documentation explicitly lists SMC Diode Solutions as the origin to guarantee material traceability and parameter consistency.

Single Zener Diodes Selection Notes

Select this component when a 51 V regulation point is required in a through-hole design. The DO-35 package offers a compact form factor compared to larger power packages while maintaining sufficient thermal handling for low-power applications. Consider the ±5% tolerance if tighter voltage accuracy is needed, in which case alternative series codes may be necessary.

Single Zener Diodes Part Context

The 1N5262 belongs to the broader 1N52xx series of 500 mW Zener diodes, which covers a voltage range typically from 2.4 V to 75 V. This series is widely adopted in general-purpose electronics for biasing and protection. The DO-35 glass package is a standard industry footprint, ensuring compatibility with existing PCB footprints designed for legacy through-hole components.

Single Zener Diodes Replacement Considerations

Direct substitutes include 1N5262B from other manufacturers, which shares identical electrical specifications and pinout. Verify that replacement parts maintain the same DO-35 package dimensions and hermetic sealing characteristics to ensure mechanical fit and reliability.
