Product details
Overview
JAN1N4614-1/TR 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/TR datasheet, JAN1N4614-1/TR pinout, JAN1N4614-1/TR application, or JAN1N4614-1/TR equivalent, this page delivers verified Zener voltage, thermal derating behavior, noise density (1 µV/√Hz), metallurgical bond construction, and MIL-qualified reliability data required for high-reliability analog reference design and qualification documentation.
Technical Context
This device operates as a reverse-biased Zener regulator with fixed 1.8 V nominal breakdown voltage at 250 mA test current. Its internal metallurgical bond ensures stable junction characteristics across temperature extremes (-65 °C to +175 °C) and radiation environments, supporting operation under MIL-STD-750 ESD testing and inherent radiation hardness per MicroNote 050.
The diode exhibits low noise density (1 µV/√Hz), minimal capacitance (typical <2 pF per Figure 3), and a negative temperature coefficient (-0.075 %/°C), enabling stable low-voltage reference generation where drift compensation and low-noise performance are critical - such as in sensor biasing and analog front-end calibration circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 1.8 V at 250 mA - defines precise low-voltage regulation point for reference circuits |
| Zener Test Current | 250 mA - standard operating point for voltage and impedance specification |
| Dynamic Impedance | 1200 Ω at IZT - determines regulation stiffness and output voltage variation under load changes |
| Power Dissipation | 500 mW at 25 °C - sets maximum continuous DC power before thermal derating begins at 50 °C |
| Temperature Coefficient | -0.075 %/°C - quantifies voltage drift with ambient temperature, critical for stability in uncontrolled environments |
| Noise Density | 1 µV/√Hz - enables ultra-low-noise reference applications below 3 kHz bandwidth |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4614US-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads | Used where board space is constrained and reflow assembly is required | Select when transitioning from through-hole to SMT without changing regulation performance |
| JANTX1N4614-1 | Identical DO-35 package and electrical parameters; screened to JANTX level (higher screening rigor than JAN) | Required for programs specifying JANTX reliability level per MIL-PRF-19500 | Choose when procurement documentation mandates JANTX qualification over JAN |
Compared with JAN1N4614-1/TR, 1N4614US-1 offers identical regulation performance in a compact SMT form factor, while JANTX1N4614-1 provides enhanced screening for mission-critical subsystems - both retain the same 1.8 V Zener voltage, 1200 Ω impedance, and -0.075 %/°C TC.

FAQ
What is the Zener voltage tolerance for JAN1N4614-1/TR?
JAN1N4614-1/TR has a nominal Zener voltage of 1.8 V with ±5% tolerance, consistent with the standard JEDEC registration for the 1N4614-1 series. This tolerance is specified at 25 °C with the diode in thermal equilibrium and applies to all JAN-level units per MIL-PRF-19500/435 screening requirements. The JAN1N4614-1/TR maintains this tolerance across its qualified operating temperature range.
Does JAN1N4614-1/TR require heatsinking in typical applications?
No, JAN1N4614-1/TR does not require external heatsinking in standard applications due to its 500 mW power rating and low thermal resistance junction-to-lead (250 °C/W). When mounted with 3/8 inch (10 mm) lead length from body on a typical PCB, it safely dissipates full rated power at ambient temperatures up to 50 °C before linear derating begins. The JAN1N4614-1/TR is designed for direct axial-lead mounting without auxiliary thermal management.
Is JAN1N4614-1/TR RoHS compliant?
No, JAN1N4614-1/TR is not RoHS compliant. Per the manufacturer's nomenclature and datasheet T4-LDS-0245-2, RoHS compliance (suffix "e3") is available only on commercial-grade versions of the 1N4614-1 series. The JAN prefix denotes military-qualified product with tin-lead plating, and the "TR" suffix indicates tape-and-reel packaging - neither implies RoHS compliance. JAN1N4614-1/TR uses traditional solderable tin-lead terminations per MIL-STD-750.
What is the maximum reverse leakage current for JAN1N4614-1/TR?
The maximum reverse leakage current for JAN1N4614-1/TR is 3.5 µA at VR = 1.0 V, measured at 25 °C. This value is specified in the Electrical Characteristics table on page 3 of the official datasheet and reflects the device's tight leakage control - critical for low-power standby regulation and high-impedance reference applications. The JAN1N4614-1/TR maintains this leakage performance across its qualified temperature range.
Can JAN1N4614-1/TR be used in surface-mount designs?
No, JAN1N4614-1/TR is packaged in the axial-leaded DO-35 (DO-204AH) glass case and is intended for through-hole mounting. For surface-mount use, Microsemi offers the functionally equivalent 1N4614US-1 in DO-213AA package. While electrical parameters match, the JAN1N4614-1/TR's leaded construction and JAN qualification make it unsuitable for reflow or wave soldering processes - its mechanical and thermal profile is optimized for axial insertion and hand-soldering in ruggedized assemblies.
