1N5250B R0G

Single Zener Diodes Overview

The Taiwan Semiconductor 1N5250B R0G is a single-die Zener diode housed in a DO-35 glass axial package. It provides a nominal Zener voltage of 20 V with a standard tolerance of ±5%. The device operates at a test current of 6.2 mA and dissipates up to 500 mW of power. Key electrical characteristics include a maximum dynamic impedance of 25 Ω, a forward voltage of 1.1 V at 200 mA, and a leakage current of 0.1 µA at 15 V reverse bias. The junction temperature range spans from -65 °C to +200 °C.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging configuration. The 'R0G' designation indicates a reel packing format containing 10,000 units per 14-inch reel. Confirm that the component meets RoHS compliance requirements for your assembly process. Ensure the DO-35 package dimensions align with your PCB footprint specifications before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a precise 20 V regulation point is required within a low-power circuit. The DO-35 glass package offers high thermal stability suitable for demanding environments. Consider the 5% voltage tolerance and 25 Ω dynamic impedance when designing precision reference circuits. Verify that the 500 mW power dissipation rating accommodates the expected operating conditions and ambient temperatures.

Single Zener Diodes Part Context

This part belongs to the 1N5221B through 1N5263B series manufactured by Taiwan Semiconductor. The series covers a wide Zener voltage range from 2.4 V to 56 V. All devices in this family share the same DO-35 hermetically sealed glass case and 500 mW power dissipation capability. The 1N5250B specifically targets the 20 V segment of this standardized product line.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering the 1N5250B specification in a DO-35 package. Verify that substitute parts match the 20 V nominal voltage, 5% tolerance, and 500 mW power rating. Ensure the replacement maintains the same hermetic sealing and lead plating specifications for compatibility.
