1N4134B

Single Zener Diodes Overview

The Microchip Technology 1N4134B is a 500 mW metallurgically bonded glass Zener diode in the axial-lead DO-35 package. It provides a nominal Zener voltage of 91 V with a standard tolerance of ±5%. The device operates within a junction temperature range of -65 °C to +175 °C and features a maximum reverse leakage current of 10 µA at 69.2 V. Electrical characteristics include a test current of 250 µA, a dynamic impedance of 1200 Ohms, and a noise density of 40 µV/√Hz.

Single Zener Diodes Feature Summary

• Internal metallurgical bond construction for high reliability
• Hermetically sealed glass DO-35 (DO-204AH) package
• Inherently radiation hard design
• Non-sensitive to electrostatic discharge

Single Zener Diodes Applications

• Voltage regulation over broad ranges of current and temperature
• High reliability applications requiring MIL-PRF-19500/435 qualification
• General purpose Zener regulation circuits

Single Zener Diodes Procurement Notes

Verify that the specific part number includes the 'B' suffix for the required tolerance level, as the datasheet primarily lists the standard 5% tolerance version without this suffix. Confirm RoHS compliance status if applicable, noting that commercial versions may differ from qualified levels. Ensure the ordering suffix matches the desired packaging option, such as tape and reel availability.

Single Zener Diodes Selection Notes

Select this component when a 91 V Zener reference is required in an axial-lead glass package. Consider the 1200 Ohm dynamic impedance and 40 µV/√Hz noise density for circuit stability requirements. Verify thermal derating needs against the 500 mW power rating at elevated ambient temperatures.
