1N4104D-1

Single Zener Diodes Overview

The Microchip Technology 1N4104D-1 is a 500 mW metallurgically bonded glass Zener diode with a nominal voltage of 10.0 V and a tight 1% tolerance. It operates within an extended temperature range from -65 °C to +175 °C in a hermetically sealed axial-lead DO-35 package. The device features a maximum dynamic impedance of 200 Ohms, a test current of 250 µA, and a maximum reverse leakage current of 7.6 µA at the rated voltage. Qualified per MIL-PRF-19500/435 for high-reliability applications, it provides stable voltage regulation across broad current and temperature variations.

• Precision voltage reference and regulation systems
• Harsh environment electronic equipment requiring wide temperature operation
• Radiation-hardened power supply designs

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required military qualification level (JAN, JANTX, JANTXV, or JANS) as commercial versions lack these certifications. Confirm RoHS compliance requirements, noting that lead-free plating is available only on commercial grade parts. Ensure the requested tolerance aligns with the 'D' suffix designation for 1% accuracy before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when strict voltage stability and radiation hardness are mandatory. The 1% tolerance ensures precise regulation without external trimming. Verify that the operating current remains near the 250 µA test point to maintain specified impedance and noise characteristics. Consider the thermal derating curve if ambient temperatures exceed standard limits to prevent exceeding the 500 mW power dissipation rating.
