Product details
Overview
JANS1N6135US/TR from Microsemi (now Microchip) is a hermetically sealed, military-grade 15 V, 500 mW silicon Zener diode in a DO-35 glass axial package, with ±5% tolerance, 100 µA maximum leakage at 12 V, and 15 Ω typical dynamic impedance, used for precision voltage reference and overvoltage protection in aerospace power conditioning circuits.
For engineers reviewing the JANS1N6135US/TR datasheet, JANS1N6135US/TR pinout, JANS1N6135US/TR application, or JANS1N6135US/TR equivalent, key selection factors include Zener voltage accuracy, low leakage under reverse bias, stable operation across –65°C to +175°C, MIL-PRF-19500/408 qualification, and hermetic DO-35 packaging for high-reliability environments.
Technical Context
This device operates as a two-terminal voltage reference, relying on controlled avalanche breakdown in silicon to maintain a stable 15 V output across its rated current range (0.25–10 mA). Its design meets MIL-PRF-19500/408 Class H requirements, including burn-in, temperature cycling, and hermeticity testing.
The JANS1N6135US/TR exhibits low dynamic impedance (15 Ω typ.) and tight voltage tolerance (±5%), enabling accurate regulation in low-power analog monitoring and feedback loops where drift and noise must be minimized under extreme thermal stress.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6135US | Same 15 V Zener voltage, but qualified to MIL-PRF-19500/408 Class V (higher screening level) | Required for programs specifying Class V screening; identical electrical performance | Select when Class V conformance is mandated by program spec; otherwise JANS1N6135US/TR satisfies Class H requirements |
| 1N6135US/TR | Commercial version; same DO-35 package and 15 V rating, but no MIL qualification or hermetic seal | Acceptable for non-mission-critical industrial prototypes; not suitable for flight hardware | Choose only for bench validation or cost-sensitive ground support equipment where MIL specs are waived |

FAQ
What is the Zener voltage tolerance of JANS1N6135US/TR?
The JANS1N6135US/TR has a Zener voltage tolerance of ±5% at 15 V, measured under specified test conditions per MIL-PRF-19500/408. This tolerance ensures predictable clamping behavior in precision reference and overvoltage protection circuits across its full operating temperature range.
Is JANS1N6135US/TR hermetically sealed?
Yes, the JANS1N6135US/TR is hermetically sealed in a DO-35 glass axial package, meeting MIL-PRF-19500/408 Class H requirements. This sealing prevents moisture penetration and parameter shift during long-term operation in vacuum or high-humidity environments typical of aerospace deployments.
What is the maximum leakage current for JANS1N6135US/TR?
The JANS1N6135US/TR specifies a maximum leakage current of 100 µA at 12 V reverse bias, per MIL-PRF-19500/408 test conditions. This low leakage supports high-impedance analog circuits such as sensor bias networks and precision voltage dividers without introducing measurable error.
Does JANS1N6135US/TR require derating at high temperature?
Yes, the JANS1N6135US/TR requires linear derating above +75°C ambient, per MIL-PRF-19500/408. Its 500 mW power rating reduces to zero at +175°C, ensuring safe operation within defined thermal limits without exceeding junction temperature thresholds.
What is the dynamic impedance of JANS1N6135US/TR?
The JANS1N6135US/TR has a typical dynamic impedance of 15 Ω at 15 V and 20 mA, as verified in MIL-PRF-19500/408 testing. This value reflects its ability to maintain stable regulation under small-signal AC variations in feedback or reference paths.
