1N4130-1

Single Zener Diodes Overview

The Microchip Technology 1N4130-1 is a 500 mW metallurgically bonded glass Zener diode in the axial-lead DO-35 package. It provides a nominal Zener voltage of 68 V at a test current of 250 µA, with a maximum dynamic impedance of 700 Ohms and a reverse leakage current of 0.01 µA. The device supports a maximum regulator current of 5.6 mA and exhibits a temperature coefficient of +0.100 %/°C. Qualified per MIL-PRF-19500/435, it operates within a junction temperature range of -65 °C to +175 °C.

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required reliability level (JAN, JANTX, JANTXV, or JANS) as specified by MIL-PRF-19500/435. Confirm RoHS compliance status if applicable, noting that commercial versions may differ from qualified levels. Ensure the specific tolerance class aligns with system requirements before procurement.

Single Zener Diodes Selection Notes

Select this component when a stable 68 V reference is needed in harsh environments. The positive temperature coefficient makes it suitable for higher voltage regulation needs. Verify thermal derating curves against the expected ambient conditions to ensure the 500 mW power rating remains sufficient under all operating scenarios.

Single Zener Diodes Part Context

This part belongs to the 1N4099-1 through 1N4135-1 series of 500 mZener regulators. These devices are JEDEC registered and offer voltages from 1.8 V to 100 V.
