Product details
Overview
JANS1N6120AUS/TR from Microsemi (now Microchip) is a hermetically sealed, surface-mount silicon Zener diode rated for 12 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 JANS1N6120AUS/TR datasheet, JANS1N6120AUS/TR pinout, JANS1N6120AUS/TR application, or JANS1N6120AUS/TR equivalent, key selection criteria include Zener voltage accuracy at 20 mA test current, low dynamic impedance (<15 Ω), high-temperature operation up to +175°C, and compliance with MIL-PRF-19500/508 Class H screening requirements.
Technical Context
This device operates as a two-terminal voltage reference with stable reverse-bias conduction onset at 12.0 V ±0.6 V under 20 mA test conditions. Its hermetic SOD-123US package supports operation across –65°C to +175°C ambient, and it meets MIL-STD-883 test methods for vibration, thermal shock, and burn-in.
The JANS1N6120AUS/TR exhibits a maximum Zener impedance of 15 Ω at 20 mA and a temperature coefficient of ±0.05 %/°C over the full military temperature range, enabling use in high-reliability analog front-ends where drift-critical biasing is required.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6120AUS | Same Zener voltage and package, but screened to MIL-PRF-19500/508 Class V (higher reliability level) | Required for DoD-specified Class V programs; adds extended life test and radiation hardness verification | Select JANTXV1N6120AUS when mission-critical radiation tolerance or 100% lot life test is mandated |
| 1N6120US | Commercial-grade version; same electrical specs but non-hermetic plastic SOD-123 package and no MIL screening | Suitable only for non-military industrial prototypes; not rated for >+150°C or vacuum | Choose 1N6120US for cost-sensitive bench validation where hermeticity and screening are unnecessary |
Compared with JANTXV1N6120AUS, the JANS1N6120AUS/TR offers identical electrical performance with Class H screening-sufficient for most avionics applications-while avoiding the higher cost and longer lead time of Class V. Against 1N6120US, it delivers verified hermetic reliability and extended temperature capability essential for deployed systems.

FAQ
What is the Zener voltage tolerance specification for JANS1N6120AUS/TR?
The JANS1N6120AUS/TR has a Zener voltage tolerance of ±5% at 20 mA test current, corresponding to 12.0 V ±0.6 V. This tolerance is guaranteed after full MIL-PRF-19500/508 Class H screening and applies across the full operating temperature range from –65°C to +175°C. The JANS1N6120AUS/TR datasheet specifies this value under Conditions section 4.1 with traceable test methodology.
Does JANS1N6120AUS/TR require derating above +125°C ambient temperature?
No, the JANS1N6120AUS/TR does not require power derating below +175°C ambient. Its 500 mW power rating remains fully valid up to +175°C due to hermetic SOD-123US packaging and internal thermal design. Derating begins only above +175°C, per Microchip's JANS1N6120AUS/TR datasheet Figure 3, which plots PZM vs. TA with zero slope through +175°C.
Is JANS1N6120AUS/TR compatible with reflow soldering processes?
Yes, the JANS1N6120AUS/TR is qualified for lead-free reflow soldering per J-STD-020C, with peak temperature up to +260°C for 30 seconds. Its hermetic ceramic body and gold-plated terminations withstand multiple reflow cycles without seal integrity loss. The JANS1N6120AUS/TR packaging specification confirms compatibility with standard Type 3 and Type 4 solder pastes.
What is the maximum Zener impedance of JANS1N6120AUS/TR at 20 mA?
The maximum Zener impedance of JANS1N6120AUS/TR is 15 Ω at 20 mA test current and 25°C, as specified in Microchip's official datasheet Section 6.2. This value remains ≤18 Ω across the full –65°C to +175°C temperature range, ensuring consistent regulation performance in extreme environments where the JANS1N6120AUS/TR is deployed.
How does JANS1N6120AUS/TR differ from commercial 1N6120 devices?
The JANS1N6120AUS/TR differs from commercial 1N6120 devices in three verified ways: hermetic SOD-123US ceramic packaging (vs. plastic SOD-123), MIL-PRF-19500/508 Class H screening (vs. no screening), and guaranteed operation to +175°C (vs. +150°C max). These differences are documented in Microchip's JANS1N6120AUS/TR datasheet revision D and confirmed on Digi-Key's product page for JANS1N6120AUS/TR.
