Product details
Overview
JAN1N4627-1 from Microsemi is a 500 mW, 6.2 V metallurgically bonded glass Zener diode in DO-35 package, qualified to JANS level per MIL-PRF-19500/435, with ±1% voltage tolerance, 5 mA maximum reverse current at 5.0 V, and +0.050%/°C temperature coefficient - used for precision voltage regulation in aerospace power conditioning circuits.
For engineers reviewing the JAN1N4627-1 datasheet, JAN1N4627-1 pinout, JAN1N4627-1 application, or JAN1N4627-1 equivalent, key selection criteria include Zener voltage stability under thermal stress, low noise density (5 µV/√Hz), radiation hardness, hermetic DO-35 packaging, and military-grade reliability qualification.
Technical Context
This device operates as a two-terminal voltage reference in reverse-bias breakdown mode, with Zener test current IZT = 250 µA and dynamic impedance ZZT = 1200 Ω at that point. Its metallurgical bond construction ensures stable junction behavior across -65°C to +175°C operating range.
The diode exhibits a positive temperature coefficient of +0.050%/°C above 6.2 V, enabling predictable drift compensation in high-reliability analog references. Noise density is specified at 5 µV/√Hz, supporting low-noise signal conditioning in sensitive instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 6.2 V ±1% at 250 µA - defines precise regulation setpoint for reference design |
| Power Dissipation | 500 mW max at 25°C - supports stable operation in conduction-limited PCB layouts |
| Dynamic Impedance ZZT | 1200 Ω at IZT - determines output impedance and load regulation sensitivity |
| Reverse Current IR | 5.0 µA max at 5.0 V - ensures low leakage in standby or low-power bias networks |
| Temp Coefficient αVZ | +0.050%/°C - enables predictable voltage drift modeling over full military temperature range |
| Noise Density ND | 5 µV/√Hz - critical for low-noise analog references in telemetry and sensor front-ends |
| Junction Temp Range | -65°C to +175°C - validated for extended operation in space-grade and avionics environments |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4627UR-1 | Same electrical specs; DO-213AA surface-mount package instead of DO-35 axial | Requires SMT reflow process; unsuitable for through-hole prototyping or high-vibration mechanical retention | Select when board space is constrained and automated assembly is available |
| JANS1N4627-1 | Identical electrical and mechanical specs; certified to JANS (Class K) rather than JAN level | Required for spaceflight missions where full Class K screening and lot traceability are mandated | Select when full NASA/GSFC Class K documentation and radiation test reports are contractually required |
Compared with JAN1N4627-1, 1N4627UR-1 offers footprint reduction but sacrifices mechanical robustness and hand-solderability, while JANS1N4627-1 adds full space-grade screening at higher cost and longer lead time - choice depends on mission assurance tier and assembly infrastructure.

FAQ
What is the Zener voltage tolerance for JAN1N4627-1?
JAN1N4627-1 has a nominal Zener voltage of 6.2 V with ±1% tolerance, confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This tight tolerance is achieved via post-process screening and applies at 250 µA test current and 25°C ambient temperature.
Is JAN1N4627-1 RoHS compliant?
No, JAN1N4627-1 is not RoHS compliant. Per the nomenclature table on page 2, the "e3" suffix denotes RoHS compliance, which is only available on commercial-grade versions. JAN1N4627-1 carries no suffix and uses tin-lead plating per MIL-STD-750.
What is the maximum reverse current specification for JAN1N4627-1?
JAN1N4627-1 specifies a maximum reverse current (IR) of 5.0 µA at VR = 5.0 V, as listed in the Electrical Characteristics table. This value reflects leakage performance under sub-breakdown conditions and is measured at 25°C.
Does JAN1N4627-1 require heatsinking in typical applications?
No, JAN1N4627-1 does not require external heatsinking in standard operation. Its 500 mW power rating and RθJL = 250°C/W allow safe dissipation at ambient temperatures ≤50°C with 3/8″ lead length, per the Maximum Ratings table on page 1.
What is the temperature coefficient of JAN1N4627-1 and how is it applied?
JAN1N4627-1 has a temperature coefficient αVZ of +0.050%/°C, meaning its Zener voltage increases by 0.050% per degree Celsius rise above 25°C. This linear drift is documented in the Electrical Characteristics table and must be factored into reference stability budgets for systems operating across -65°C to +175°C.
