Overview
The Microchip Technology 1N6486US/TR is a surface mount Zener voltage regulator with a nominal breakdown voltage of 3.6 V and a maximum power dissipation of 1.5 W at 25 °C ambient temperature. It features a test current (IZT) of 69 mA, a maximum dynamic impedance (ZZT) of 10 Ohms, and a maximum reverse leakage current of 50 µA at the specified voltage. The device operates within a junction and storage temperature range of -65 °C to +175 °C.
Feature Summary
- Hermetically sealed voidless glass package with internal metallurgical bonds for high reliability.
- Qualified per MIL-PRF-19500/406 for JAN, JANTX, JANTXV, and JANS levels.
- Inherently radiation hard and non-sensitive to electrostatic discharge.
Applications
- High-reliability military applications where failure cannot be tolerated.
- Voltage regulation over broad operating current and temperature ranges.
- Radiation-hardened circuit designs.
Procurement Notes
Verify the specific qualification level (JAN, JANTX, JANTXV, or JANS) required for your application, as this determines the manufacturing lot traceability and testing standards. Confirm that the tape and reel packaging meets EIA-481-B specifications if automated placement is utilized. Ensure compatibility with tin/lead terminal finishes unless commercial RoHS-compliant versions are explicitly sourced.
Selection Notes
Select this component when a 3.6 V reference is needed in a surface mount form factor requiring extreme thermal stability up to 175 °C. The 1.5 W power rating supports significant current handling compared to smaller packages. Verify that the 10 Ohm dynamic impedance meets the noise and regulation requirements of the target circuit design.
Part Context
This part belongs to the 1N6485US through 1N6491US series of industry-recognized 1.5 Watt Zener diodes. These devices serve as surface mount equivalents to popular JEDEC registered axial-lead series, offering identical electrical performance in a compact D-5A-2 MELF package suitable for dense PCB layouts.
Replacement Considerations
Direct replacements include other parts from the 1N6485US–1N6491US series or the commercial 1N4460US–1N4496US series, provided the lower reliability standards of the commercial grade are acceptable for the intended environment.
