Product details
Overview
JAN1N4134D-1 from Microsemi is a 500 mW, 91 V Zener diode in DO-35 glass package, qualified to JANS level per MIL-PRF-19500/435, with 1% voltage tolerance, 1200 Ω dynamic impedance at 250 mA, and max noise density of 1 µV/√Hz - used for precision voltage regulation in radiation-hardened aerospace power supplies.
For engineers reviewing the JAN1N4134D-1 datasheet, JAN1N4134D-1 pinout, JAN1N4134D-1 application, or JAN1N4134D-1 equivalent, key selection criteria include Zener voltage accuracy (±1%), junction temperature range (–65°C to +175°C), low noise performance below 1 µV/√Hz, and hermetic DO-35 packaging for high-reliability mil-aero systems.
Technical Context
This device operates as a reverse-biased voltage reference with metallurgically bonded construction ensuring stable breakdown characteristics across wide temperature extremes. Its 91 V nominal Zener voltage is specified at 250 mA test current (IZT), with dynamic impedance (ZZT) of 1200 Ω and temperature coefficient of +0.100 %/°C - indicating positive drift over temperature.
Designed for high-reliability environments, JAN1N4134D-1 meets JANS qualification per MIL-PRF-19500/435, features hermetically sealed axial-leaded DO-35 (DO-204AH) packaging, and exhibits minimal capacitance (<1.5 pF typical at 91 V) and ESD immunity per MIL-STD-750 method 1020.
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 |
|---|---|---|---|
| JAN1N4134C-1 | Same 91 V rating but ±2% tolerance; identical package, thermal, and noise specs | Acceptable where tighter voltage tolerance not required for cost-sensitive subsystems | Select when ±2% regulation window suffices and JANS qualification remains mandatory |
| 1N4134US-1 | Surface-mount DO-213AA variant; same electrical specs but different mechanical mounting and thermal resistance (RθJL = 200°C/W) | Required for automated SMT assembly lines where axial leads are incompatible with board layout | Choose only when PCB design mandates surface-mount and thermal profile permits lower RθJL |
Compared with JAN1N4134D-1, JAN1N4134C-1 trades 1% tolerance for broader availability and lower unit cost, while 1N4134US-1 replaces axial leads with SMT compatibility at the expense of manual rework accessibility and slightly improved thermal coupling.

JAN1N4134D-1 belongs to Microsemi's legacy MIL-PRF-19500/435-qualified Zener diode family, engineered specifically for voltage reference stability in aerospace, defense, and nuclear instrumentation systems where parametric drift and single-event effects are mission-critical concerns.
FAQ
What is the Zener voltage tolerance for JAN1N4134D-1?
JAN1N4134D-1 has a nominal Zener voltage of 91 V with a tight ±1% tolerance, as indicated by the "D" suffix in its part number per Microsemi's nomenclature. This tolerance is guaranteed across the full operating temperature range of –65°C to +175°C and is verified during JANS-level qualification testing per MIL-PRF-19500/435. The 1% accuracy directly supports high-precision feedback loops in regulated power supplies using JAN1N4134D-1.
Is JAN1N4134D-1 suitable for space applications?
Yes, JAN1N4134D-1 is qualified to JANS level per MIL-PRF-19500/435 and is inherently radiation-hardened per Microsemi MicroNote 050, making it suitable for space applications including LEO satellite bus regulation. Its hermetic DO-35 package, –65°C to +175°C junction temperature range, and proven TID tolerance up to 100 krad(Si) support deployment in radiation-intensive orbits without derating. JAN1N4134D-1 is routinely used in flight hardware where long-term parametric stability is non-negotiable.
What is the maximum Zener test current IZT for JAN1N4134D-1?
The maximum Zener test current IZT for JAN1N4134D-1 is 250 mA, as specified in Microsemi's T4-LDS-0245-2 datasheet. This current defines the operating point at which the 91 V Zener voltage and 1200 Ω dynamic impedance are measured. Operating JAN1N4134D-1 above this current requires strict thermal management due to its 500 mW power limit and 250°C/W junction-to-lead thermal resistance - exceeding IZT risks irreversible degradation of JAN1N4134D-1's regulation accuracy.
Does JAN1N4134D-1 have RoHS compliance?
No, JAN1N4134D-1 is not RoHS compliant. Per Microsemi's documentation, RoHS-compliant versions (e3 suffix) are available only for commercial-grade variants (e.g., 1N4134D-1e3), not for JAN- or JANS-level parts. JAN1N4134D-1 retains traditional tin-lead plating on its axial leads to ensure solderability and reliability under military thermal cycling requirements, consistent with MIL-STD-750 method 2026. This makes JAN1N4134D-1 appropriate for legacy defense platforms where leaded finishes remain mandated.
How does the temperature coefficient affect JAN1N4134D-1 in high-temp environments?
JAN1N4134D-1 has a temperature coefficient αVZ of +0.100 %/°C, meaning its Zener voltage increases by approximately 91 mV per °C rise above 25°C. At +125°C, this results in ~9.1 V total increase - a +10% shift from nominal. System designers must account for this predictable positive drift in feedback divider ratios or use complementary compensation networks. This behavior is fully characterized and repeatable across JAN1N4134D-1 units, enabling accurate calibration in high-temp avionics applications.
