Product details
Overview
JANTX1N4135-1 from Microsemi is a 100 V, 500 mW axial-leaded glass Zener diode in DO-35 (DO-204AH) package, qualified to JANTX level per MIL-PRF-19500/435, with ±5% Zener voltage tolerance, 1600 Ω dynamic impedance at 250 mA test current, and 3.8 mA maximum Zener current for precision voltage regulation in high-reliability analog power supplies.
For engineers reviewing the JANTX1N4135-1 datasheet, JANTX1N4135-1 pinout, JANTX1N4135-1 application, or JANTX1N4135-1 equivalent, key selection criteria include its 100 V nominal Zener voltage, 500 mW power rating, -65 °C to +175 °C operating temperature range, metallurgically bonded construction, and MIL-qualified reliability for aerospace and defense systems.
Technical Context
The JANTX1N4135-1 operates as a reverse-biased voltage reference diode with a specified Zener voltage of 100 V at 250 mA test current (IZT), exhibiting 1600 Ω dynamic impedance (ZZT) and 0.01 µA maximum reverse leakage (IR) at 76 V. Its metallurgical bond ensures stable junction behavior under thermal cycling.
Designed for high-reliability applications, it features a temperature coefficient of +0.100 %/°C, minimal capacitance (typical <1.5 pF), and noise density of 40 µV/√Hz - consistent with Zener diodes ≥6.8 V - enabling low-noise reference generation in precision analog circuits.
Key Specifications

|---|---|
| Zener Voltage (VZ) | 100 V at 250 mA test current - defines precise regulation point for high-voltage reference circuits |
| Power Dissipation | 500 mW at 25 °C - sets maximum continuous DC power handling before thermal derating begins at 50 °C |
| Zener Impedance (ZZT) | 1600 Ω at 250 mA - indicates voltage stability under load variation; higher than lower-voltage Zeners due to physics of breakdown |
| Reverse Leakage (IR) | 0.01 µA at 76 V - ensures negligible current draw in standby, critical for low-power bias networks |
| Temp Coefficient (αVZ) | +0.100 %/°C - quantifies positive drift with temperature; requires compensation in wide-temp-range designs |
| Operating Temp Range | -65 °C to +175 °C - supports operation in extreme environments including space and military avionics |
| Package | DO-35 (DO-204AH) glass axial - hermetically sealed, leaded, and compatible with through-hole wave soldering |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4135US (Microchip) | Same 100 V Zener voltage, DO-213AA surface-mount package, 500 mW rating, but only commercial-grade (no MIL qualification) | Lacks JANTX screening; unsuitable for flight hardware or radiation-hardened systems | Select only for cost-sensitive terrestrial industrial controls where MIL-PRF-19500 compliance is not required |
| JAN1N4135-1 (Microsemi) | Identical electrical specs and DO-35 package, but qualified only to JAN level (less stringent screening than JANTX) | Lower reliability assurance; excluded from Class H or Class K military procurement | Acceptable for non-critical subsystems where full JANTX screening adds unnecessary cost and lead time |
Compared with JANTX1N4135-1, 1N4135US offers board-space savings via SMT but sacrifices reliability assurance, while JAN1N4135-1 reduces cost and qualification burden at the expense of guaranteed failure-in-time (FIT) rate and burn-in coverage.

FAQ
What is the Zener voltage tolerance for JANTX1N4135-1?
JANTX1N4135-1 has a nominal Zener voltage of 100 V with a ±5% tolerance, consistent with the standard JEDEC specification for the 1N4099–1N4135 series. This tolerance applies at 25 °C with the diode in thermal equilibrium and is verified during JANTX-level screening per MIL-PRF-19500/435.
Is JANTX1N4135-1 suitable for high-temperature environments?
Yes, JANTX1N4135-1 is rated for junction and storage temperatures from -65 °C to +175 °C. Its metallurgically bonded construction and hermetic DO-35 glass package ensure stable operation in extended temperature environments such as engine-mounted avionics or downhole oilfield electronics.
Does JANTX1N4135-1 have RoHS compliance?
No - JANTX1N4135-1 is not RoHS compliant. RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade variants (e.g., 1N4135-1e3), not for JANTX-qualified parts, as MIL-PRF-19500/435 allows exemption from RoHS for high-reliability applications requiring lead-based finishes.
What is the maximum Zener current (IZM) for JANTX1N4135-1?
The maximum Zener current (IZM) for JANTX1N4135-1 is 76.0 mA, derived from its 500 mW power rating and 100 V Zener voltage (P = V × I). This value assumes operation at 25 °C; derating applies linearly above 50 °C ambient or lead temperature.
How does the temperature coefficient affect JANTX1N4135-1 performance?
JANTX1N4135-1 has a temperature coefficient of +0.100 %/°C, meaning its Zener voltage increases by approximately 100 mV per 1 °C rise in junction temperature. This positive drift must be accounted for in high-precision references, especially over wide operating ranges beyond 25 °C.
