Overview
The Microchip Technology 1N6486 is a military-qualified Zener diode designed for high-reliability applications. It operates within a junction and storage temperature range of -65°C to +175°C. The device features a nominal Zener voltage (VZ) of 3.6 V with a test current (IZT) of 69.0 mA. Maximum dynamic impedance (ZZT) at IZT is 10 Ohms, while maximum knee impedance (ZZK) at IZK is 1.0 Ohm. Steady-state power dissipation (PD) is rated at 1.5 W at a lead temperature of +112°C. The maximum continuous regulator current (IZM) is 397 mA, and the surge current (IZSM) capability is 3.9 A.
Feature Summary
- Hermetically sealed voidless glass package construction
- Internal metallurgical bonds for robust mechanical integrity
- Triple-layer passivation for enhanced protection
- Qualified per MIL-PRF-19500/406 standards
Applications
- High-reliability voltage regulation
- Military and aerospace electronic systems
- Circuitry where failure cannot be tolerated
Procurement Notes
Verify that the specific ordering suffix matches the required reliability level (JAN, JANTX, JANTXV, or JANS). Confirm RoHS compliance status if applicable, as commercial versions differ from qualified levels. Ensure the procurement documentation explicitly references MIL-PRF-19500/406 qualification. Validate terminal plating options against environmental requirements.
Selection Notes
Select this component when a 3.6 V reference is required in a 1.5 W axial-lead package. Consider the 10 Ohm dynamic impedance for low-noise stability needs. Evaluate thermal derating curves for operation above ambient temperatures. Verify compatibility with existing board layouts requiring DO-41 form factors.
Part Context
This part belongs to the 1N6485–1N6491 series of voidless hermetically sealed glass Zener diodes. These devices are industry-recognized regulators offering selections from 3.3 to 200 volts. The series provides standard 5% tolerance alongside tighter 1% and 2% options for precision applications.
Replacement Considerations
Substitutes must match the 3.6 V nominal voltage, 1.5 W power rating, and DO-41 package. Verify equivalent MIL-PRF-19500/406 qualification levels and identical thermal characteristics.
