1N5230B_T50R

Single Zener Diodes Overview

The onsemi 1N5230B_T50R is a single silicon Zener diode with a nominal voltage of 4.7 V and a tolerance of ±5%. It operates in the DO-35 axial leaded package, supporting through-hole mounting. The device dissipates up to 500 mW at temperatures up to 75°C, with derating required above this threshold. Key electrical parameters include a maximum reverse leakage current of 5 µA, a test current of 20 mA, and a dynamic impedance of 19 Ω. It functions within an operating temperature range of -65°C to +200°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation via Zener breakdown characteristics for reference applications.
• Features hermetically sealed glass construction for environmental protection and reliability.
• Supports high-temperature operation with a maximum junction temperature of 200°C.

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels.
• Overvoltage protection stages in electronic systems.
• Clamping applications for transient suppression.

Single Zener Diodes Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package integrity and lead condition prior to assembly. Ensure storage conditions comply with moisture sensitivity requirements. Validate that the specific suffix matches the intended reel or cut tape configuration. Cross-reference part numbers with authorized distributor catalogs to avoid counterfeit risks.

Single Zener Diodes Selection Notes

Select this component when a precise 4.7 V reference is needed in a through-hole design. Consider the 5% tolerance and 19 Ω impedance for circuit accuracy requirements. Evaluate thermal management needs as power dissipation must be derated above 75°C. Compare against surface-mount alternatives if board space is constrained.
