Product details
Overview
JANS1N4135C-1/TR from Microsemi is a 100 V, 2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense voltage regulation. It delivers stable reference voltage with 3.8 mA maximum Zener current, 1600 Ω dynamic impedance at 250 mA test current, and +0.100 %/°C temperature coefficient.
For engineers reviewing the JANS1N4135C-1/TR datasheet, JANS1N4135C-1/TR pinout, JANS1N4135C-1/TR application, or JANS1N4135C-1/TR equivalent, this page provides verified electrical parameters, military qualification status, thermal derating behavior, noise density (1 μV/√Hz), and RoHS-compliant plating details specific to the TR tape-and-reel variant.
Technical Context
This device operates as a precision voltage reference in reverse-biased breakdown mode, with cathode band marking polarity. Its metallurgical bond construction ensures low noise and radiation hardness per MicroNote 050, supporting operation from –65 °C to +175 °C junction temperature.
It exhibits 1600 Ω dynamic impedance (ZZT) at IZT = 250 mA, 0.01 µA maximum reverse leakage (IR) at VR = 80 V, and linear power derating from 500 mW at 25 °C to zero at 175 °C on standard FR4 board with 4 mm² copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 100 V ±2% at 250 mA - defines precise regulation point for high-voltage reference circuits |
| Power Dissipation PM(AV) | 500 mW at 25 °C - sets maximum continuous thermal load before derating begins |
| Dynamic Impedance ZZT | 1600 Ω at IZT = 250 mA - determines output voltage stability under varying load current |
| Reverse Leakage IR | 0.01 µA at VR = 80 V - ensures minimal parasitic current in high-impedance bias networks |
| Noise Density ND | 1 µV/√Hz - enables low-noise performance in precision analog references and metrology systems |
| Temp Coefficient αVZ | +0.100 %/°C - quantifies voltage drift over temperature for system-level error budgeting |
| Junction Temp Range | –65 °C to +175 °C - supports operation in extreme environmental conditions without derating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4135US-1/TR | Same 100 V, 2% spec but in surface-mount DO-213AA package; no axial leads | Requires PCB redesign for SMT assembly; eliminates through-hole mounting and lead-forming steps | Select for automated production where board space and assembly efficiency outweigh legacy through-hole compatibility |
| JANTXV1N4135C-1/TR | Identical electrical specs and DO-35 package but qualified only to JANTXV level (not JANS); lower screening rigor | Suitable for high-reliability ground-based systems where full JANS radiation testing is not mandated | Select when cost sensitivity and schedule constraints preclude full JANS qualification testing without compromising core regulation performance |
Compared with JANS1N4135C-1/TR, the 1N4135US-1/TR enables higher-density layouts but sacrifices mechanical robustness and thermal path flexibility, while the JANTXV1N4135C-1/TR reduces procurement cost and lead time at the expense of radiation hardness validation and extended life testing required for orbital deployment.

FAQ
What is the Zener voltage tolerance of JANS1N4135C-1/TR?
JANS1N4135C-1/TR has a nominal Zener voltage of 100 V with ±2% tolerance, as indicated by the "C" suffix in its nomenclature per Microsemi's part numbering convention. This tolerance is verified at 250 mA test current and 25 °C ambient, and applies across the full qualified temperature range when used within its derated power envelope.
Is JANS1N4135C-1/TR RoHS compliant?
JANS1N4135C-1/TR uses RoHS-compliant annealed matte-tin plating on its axial leads, consistent with Microsemi's specification for JANS-level devices. The "e3" RoHS designation applies to commercial-grade variants; however, the JANS version maintains RoHS compliance while meeting MIL-PRF-19500/435 requirements including hermetic sealing and radiation hardness.
What is the maximum reverse leakage current for JANS1N4135C-1/TR?
JANS1N4135C-1/TR specifies a maximum reverse leakage current (IR) of 0.01 µA at VR = 80 V, measured at 25 °C. This ultra-low leakage supports high-impedance bias networks and precision reference dividers where parasitic current must remain below 10 nA to avoid measurable error.
How does the power derating curve apply to JANS1N4135C-1/TR?
JANS1N4135C-1/TR linearly derates from 500 mW at 25 °C to zero at 175 °C junction temperature. On a typical FR4 board with 4 mm² copper pads, derating begins at 50 °C lead temperature. Engineers must calculate actual junction temperature using RθJL = 250 °C/W and ambient conditions to ensure safe continuous operation.
What does the "TR" suffix indicate in JANS1N4135C-1/TR?
"TR" denotes tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. JANS1N4135C-1/TR is supplied in reels optimized for high-reliability manufacturing lines, with full traceability back to wafer lot and screening batch per MIL-PRF-19500/435 requirements.
