1N5259B A0G

Single Zener Diodes Overview

The 1N5259B A0G is a small signal Zener diode manufactured by Taiwan Semiconductor. It features a nominal Zener voltage of 33 V with a tolerance of 5%. The device is designed for through-hole mounting in a DO-35-2 glass axial leaded package. Key electrical specifications include a power dissipation rating of 500 mW, a maximum reverse leakage current of 100 nA, and a Zener impedance of 58 Ohms at a test current of 3.8 mA. The component supports a maximum operating temperature of +200°C and has a forward voltage of 1.1 V at 200 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation within a 5% tolerance band
• Utilizes hermetically sealed glass axial-leaded construction
• Supports high thermal stability up to +200°C junction temperature

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• Clipping and clamping applications

Single Zener Diodes Procurement Notes

Verify the specific suffix 'A0G' against the manufacturer's official datasheet to confirm packaging details and exact electrical tolerances. Ensure the procurement channel provides valid traceability documentation. Confirm RoHS compliance status as indicated in the official product specifications before finalizing orders.

Single Zener Diodes Selection Notes

Select this component when a 33 V regulation point is required in a low-power application. The DO-35 package suits standard through-hole PCB layouts. Consider the 58 Ohm impedance for dynamic load requirements. Verify that the 500 mW power rating aligns with the circuit's thermal dissipation needs under continuous operation conditions.

Single Zener Diodes Part Context

This part belongs to the 1N5257B series of 500 mW Zener diodes offered by Taiwan Semiconductor. The series covers a wide range of voltage values in the DO-35 package. The 'A0G' suffix typically denotes specific packaging or lot coding variations rather than fundamental electrical changes, though official documentation should be consulted for precise definition.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering the 1N5259B specification. Verify pinout compatibility and package dimensions (DO-35) for direct substitution. Ensure equivalent Zener voltage and power dissipation ratings are maintained in alternative sourcing options.
