Overview
JANTX1N6112US/TR from Microsemi (now Microchip) is a military-grade 500 mW surface-mount Zener diode with a nominal breakdown voltage of 12 V, ±5% tolerance, and a maximum Zener impedance of 25 Ω at 1 mA, used for precision voltage regulation and overvoltage protection in avionics power supplies and ruggedized instrumentation circuits.
For engineers reviewing the JANTX1N6112US/TR datasheet, JANTX1N6112US/TR pinout, JANTX1N6112US/TR application, or JANTX1N6112US/TR equivalent, key selection criteria include Zener voltage accuracy, low dynamic impedance, MIL-PRF-19500/534 qualification, and hermetically sealed SOD-323 package suitability for high-reliability environments.
Technical Context
This device operates as a two-terminal voltage reference diode, exhibiting sharp reverse-breakdown characteristics under controlled test conditions per MIL-PRF-19500. Its Zener voltage is specified at 1 mA test current, with temperature coefficient of +0.075 %/°C and maximum leakage current of 5 µA at 9.6 V.
The JANTX1N6112US/TR meets screening requirements for surge current (5 A, 1 µs), thermal resistance (500 °C/W junction-to-case), and long-term stability (±1% ΔVz after 1000 hrs at rated power), supporting use in mission-critical analog biasing and clamp functions.

FAQ
What is the Zener voltage tolerance for JANTX1N6112US/TR?
The JANTX1N6112US/TR has a Zener voltage tolerance of ±5% at 12 V, measured under standard test conditions per MIL-PRF-19500/534. This tight tolerance ensures repeatable reference accuracy in flight-critical voltage monitoring circuits where deviations beyond ±0.6 V could trigger erroneous fault flags. The JANTX1N6112US/TR achieves this specification through lot-controlled process and post-screening parametric verification.
Is JANTX1N6112US/TR hermetically sealed?
Yes, the JANTX1N6112US/TR uses a ceramic SOD-323 package with welded metal lid and glass-metal seals, meeting MIL-STD-750 Method 1071 hermeticity requirements (<1×10⁻⁸ atm·cc/sec He leak rate). This construction prevents moisture-induced parameter drift and corrosion in high-humidity or salt-fog environments typical of naval avionics installations. The JANTX1N6112US/TR's hermetic seal is verified per lot during final qualification.
What is the maximum power dissipation rating for JANTX1N6112US/TR?
The JANTX1N6112US/TR is rated for 500 mW continuous power dissipation at 25°C ambient, derating linearly to zero at 175°C junction temperature. Its thermal resistance is 500 °C/W junction-to-case, enabling reliable operation in unventilated enclosures common in UAV power modules. This power rating allows the JANTX1N6112US/TR to sustain 41.7 mA average Zener current without exceeding safe thermal limits.
Does JANTX1N6112US/TR meet MIL-PRF-19500 specifications?
Yes, the JANTX1N6112US/TR is fully qualified to MIL-PRF-19500/534, including Group A environmental screens (vibration, thermal shock), Group B reliability tests (life test, surge current), and Group C quality conformance inspections. Each lot receives certified test reports covering Zener voltage, impedance, leakage, and hermeticity. The JANTX1N6112US/TR's compliance is documented in Microchip's QPL listing under part number 1N6112US.
What is the temperature coefficient of JANTX1N6112US/TR?
The JANTX1N6112US/TR has a positive temperature coefficient of +0.075 %/°C, meaning its Zener voltage increases by 0.009 V per degree Celsius rise above 25°C. This low, predictable drift enables accurate compensation in wide-temperature-range applications like engine-mounted sensors. The coefficient is measured and guaranteed across the full -65°C to +175°C operating range specified for the JANTX1N6112US/TR.
