Product details
Overview
JAN1N4614-1 from Microsemi is a 500 mW, 1.8 V Zener voltage regulator diode in DO-35 glass axial-leaded package, qualified to JAN level per MIL-PRF-19500/435, with ±5% voltage tolerance, 1200 Ω dynamic impedance at 250 mA test current, and -0.075 %/°C temperature coefficient - used for precision low-voltage reference and regulation in military power supply monitoring circuits.
For engineers reviewing the JAN1N4614-1 datasheet, JAN1N4614-1 pinout, JAN1N4614-1 application, or JAN1N4614-1 equivalent, this page delivers verified electrical specs, mil-grade reliability context, thermal derating behavior, noise density (1 µV/√Hz), and direct alternatives for high-reliability analog reference design.
Technical Context
The JAN1N4614-1 operates as a reverse-biased Zener diode with metallurgically bonded junction, enabling stable voltage regulation across wide current (250 mA IZT) and temperature (-65 °C to +175 °C) ranges. Its 1.8 V nominal Zener voltage places it in the low-voltage knee region where temperature coefficient is tightly controlled at -0.075 %/°C.
It exhibits 1200 Ω dynamic impedance (ZZT) at 250 mA test current and 1 µV/√Hz noise density - critical for low-noise analog references. The DO-35 hermetic glass package ensures ESD immunity per MIL-STD-750 method 1020 and radiation hardness per Microsemi MicroNote 050.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 1.8 V ±5% at 250 mA - defines precise low-voltage reference point for biasing or feedback networks |
| Power Dissipation PM(AV) | 500 mW @ TC = 25 °C - supports continuous regulation in compact through-hole layouts with linear derating above 50 °C |
| Dynamic Impedance ZZT | 1200 Ω @ IZT = 250 mA - determines output voltage stability under load current variation |
| Noise Density ND | 1 µV/√Hz @ 1 kHz–3 kHz - enables use in low-noise instrumentation references without added filtering |
| Temp Coefficient αVZ | -0.075 %/°C - ensures predictable, monotonic drift in temperature-critical military sensor interfaces |
| Reverse Leakage IR | 3.5 µA @ VR = 1.0 V - confirms low standby current in always-on reference circuits |
| Max Regulator Current IZM | 120 mA - sets upper limit for safe continuous Zener conduction without exceeding thermal limits |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4614UR-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads | Required for PCB space-constrained designs where through-hole mounting is not feasible | Select when automated SMT assembly and board real estate optimization are priorities over manual repairability |
| JANTX1N4614-1 | Identical DO-35 package and electrical parameters; qualified to JANTX level (higher screening than JAN) | Needed for programs requiring extended burn-in, life test, and lot traceability beyond JAN requirements | Choose when program specifications mandate JANTX-level reliability documentation and test records |
Compared with JAN1N4614-1, the 1N4614UR-1 enables SMT integration without electrical compromise, while JANTX1N4614-1 adds enhanced screening rigor - both retain identical 1.8 V regulation, -0.075 %/°C drift, and 1 µV/√Hz noise for seamless functional substitution in mil-spec systems.

FAQ
What is the Zener voltage tolerance of JAN1N4614-1?
JAN1N4614-1 has a nominal Zener voltage of 1.8 V with a ±5% tolerance, as defined in the JEDEC-registered specification and confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This tolerance applies at 250 mA test current and 25 °C ambient temperature, and is standard for the JAN-level variant unless otherwise marked.
Does JAN1N4614-1 meet MIL-PRF-19500/435 requirements?
Yes, JAN1N4614-1 is qualified per MIL-PRF-19500/435 at the JAN reliability level, as explicitly stated in the Description section on page 1 of T4-LDS-0245-2 Rev. 1. This includes screening for temperature cycling, mechanical shock, vibration, and hermeticity - making it suitable for defense and aerospace applications requiring certified high-reliability components.
What is the maximum allowable junction temperature for JAN1N4614-1?
The maximum junction and storage temperature for JAN1N4614-1 is +175 °C, as specified in the Maximum Ratings table on page 1 of T4-LDS-0245-2 Rev. 1. Derating begins linearly at 50 °C lead temperature, reaching zero power dissipation at 175 °C - consistent with its DO-35 package thermal resistance of 250 °C/W junction-to-lead.
How does the noise performance of JAN1N4614-1 compare to higher-voltage Zeners in the same family?
JAN1N4614-1 delivers 1 µV/√Hz noise density at 1.8 V, which is the lowest in the 1N4614–1N4627 series - significantly lower than 6.8 V+ parts (e.g., 40 µV/√Hz for 1N4625-1). This ultra-low noise is confirmed in the Features section and Figure 1 of T4-LDS-0245-2 Rev. 1, making JAN1N4614-1 optimal for low-voltage, low-noise analog references.
Is JAN1N4614-1 RoHS compliant?
No, JAN1N4614-1 is not RoHS compliant. Per the Features section on page 1 of T4-LDS-0245-2 Rev. 1, RoHS-compliant versions (e3 suffix) are available only for commercial-grade variants - the JAN prefix denotes military-qualified parts with tin-lead plating, which falls outside RoHS exemption scope for high-reliability applications.
