1N4113-1

Single Zener Diodes Overview

The Microchip Technology 1N4113-1 is a 500 mW metallurgically bonded glass Zener diode in an axial-leaded DO-35 (DO-204AH) package. It provides a nominal Zener voltage of 19 V with a standard tolerance of ±5%. The device operates within a junction and storage temperature range of -65°C to +175°C. Electrical characteristics include a maximum reverse leakage current of 50 nA at 14.5 V, a dynamic impedance of 150 Ohms, and a forward voltage of 1.1 V at 200 mA.

Single Zener Diodes Feature Summary

• Hermetically sealed internal metallurgical bond for high reliability
• Qualified per MIL-PRF-19500/435 standards including JANS level
• Flexible axial-lead mounting terminals for through-hole integration

Single Zener Diodes Applications

• Voltage regulation over broad ranges of current and temperature
• High reliability applications requiring radiation hardness
• Circuits demanding minimal capacitance and low noise density

Single Zener Diodes Procurement Notes

Verify the specific reliability qualification level required for the application, as the series supports JAN, JANTX, JANTXV, and JANS variants. Confirm RoHS compliance status, noting that commercial versions may differ from military-qualified parts. Ensure the ordering suffix matches the desired tolerance and packaging configuration before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 19 V reference with ±5% tolerance is needed in a hermetically sealed glass package. Consider the 500 mW power dissipation limit and derating curves for thermal management. Verify that the 150 Ohm dynamic impedance meets the circuit's stability requirements and that the operating temperature range covers the environmental extremes.
