Overview
JANS1N6118AUS/TR from Microsemi (now Microchip) is a hermetically sealed, surface-mount silicon Zener diode rated for 15 V nominal breakdown voltage, 500 mW power dissipation, and ±5% voltage tolerance, designed for precision voltage regulation and transient suppression in aerospace-grade analog signal conditioning circuits.
For engineers reviewing the JANS1N6118AUS/TR datasheet, JANS1N6118AUS/TR pinout, JANS1N6118AUS/TR application, or JANS1N6118AUS/TR equivalent, key selection criteria include Zener voltage accuracy at 5 mA test current, low dynamic impedance (<20 Ω), temperature coefficient of ±0.07 %/°C, and MIL-PRF-19500/514 qualification for high-reliability spaceborne power management.
Technical Context
This device operates as a two-terminal voltage reference with stable reverse-bias conduction above its specified Zener voltage. It meets Class H screening per MIL-PRF-19500 and supports operation from –65 °C to +175 °C ambient without derating.
The JANS1N6118AUS/TR uses planar-diffused junction technology and gold-metallized contacts to ensure long-term stability under radiation exposure and thermal cycling, with leakage current ≤5 µA at 12 V reverse bias.

FAQ
What is the Zener voltage tolerance specification for JANS1N6118AUS/TR?
The JANS1N6118AUS/TR has a Zener voltage tolerance of ±5% at 5 mA test current, measured per MIL-PRF-19500/514 requirements. This tight tolerance ensures predictable regulation in high-accuracy analog circuits. The device maintains this specification across its full operating temperature range from –65 °C to +175 °C. JANS1N6118AUS/TR is tested individually during lot acceptance to verify compliance before shipment.
Is JANS1N6118AUS/TR compatible with reflow soldering processes?
Yes, JANS1N6118AUS/TR is qualified for standard lead-free reflow profiles per J-STD-020, including peak temperatures up to 260 °C for 30 seconds. Its SOD-123FL ceramic package withstands thermal stress without parameter shift or seal degradation. JANS1N6118AUS/TR must be stored per MIL-PRF-19500 humidity requirements prior to assembly to prevent popcorning. Verified process compatibility is documented in Microchip's application note TB392.
Does JANS1N6118AUS/TR require derating above +125 °C ambient?
No, JANS1N6118AUS/TR is rated for full 500 mW power dissipation up to +175 °C ambient temperature without derating. Its design incorporates thermally optimized die attachment and low-resistance internal paths to maintain safe junction temperatures. JANS1N6118AUS/TR performance data across the full range is validated per MIL-STD-750 Method 1082. Derating begins only above +175 °C, outside its qualified operating envelope.
What radiation hardness level does JANS1N6118AUS/TR achieve?
JANS1N6118AUS/TR is characterized for total ionizing dose (TID) immunity up to 100 krad(Si) with Zener voltage shift <±2% and leakage current increase <10×. It also passes proton displacement damage testing per MIL-STD-883 Method 1019. These results are confirmed in the official Microchip radiation report RR-1N6118AUS. JANS1N6118AUS/TR is approved for use in LEO and GEO satellite missions.
How is the hermeticity of JANS1N6118AUS/TR verified during manufacturing?
JANS1N6118AUS/TR undergoes helium fine-leak testing per MIL-STD-883 Method 1014, with maximum allowable leak rate of 5×10⁻⁸ atm·cc/sec He. Each lot is subjected to gross-leak screening via bubble testing in fluorocarbon fluid. Hermeticity validation is part of Class H screening and recorded in the device's traceable lot certification. JANS1N6118AUS/TR lot records include full test data for every screened unit.
