Product details
Overview
JAN1N4617D-1 from Microsemi is a 500 mW, 2.4 V Zener diode in DO-35 glass package, qualified to JAN reliability level per MIL-PRF-19500/435, with 1% voltage tolerance, 1400 Ω dynamic impedance at 250 mA test current, and -0.075 %/°C temperature coefficient - used for precision voltage reference and regulation in military-grade power supply circuits.
For engineers reviewing the JAN1N4617D-1 datasheet, JAN1N4617D-1 pinout, JAN1N4617D-1 application, or JAN1N4617D-1 equivalent, key selection criteria include Zener voltage tolerance (1%), junction temperature range (-65 to +175 °C), metallurgical bond construction, noise density (1 µV/√Hz), and MIL-qualified reliability level - all critical for high-reliability analog reference design.
Technical Context
This device operates as a reverse-biased voltage regulator with a nominal Zener voltage of 2.4 V at 250 mA test current (IZT), exhibiting 1400 Ω dynamic impedance (ZZT) and a negative temperature coefficient of -0.075 %/°C. Its metallurgically bonded glass structure ensures stable breakdown characteristics under thermal cycling and radiation exposure.
Designed for operation across -65 to +175 °C junction temperature, it delivers regulated voltage with ≤1.0 µA reverse leakage (IR) at VR = 1.0 V and supports up to 95 mA maximum Zener current (IZM) at 25 °C ambient - enabling use in low-power, high-stability reference nodes where long-term parametric drift must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 2.4 V ±1% at IZT = 250 mA - defines precise regulation point for low-voltage reference circuits |
| Power Dissipation | 500 mW at TC = 25 °C - sets thermal limit for continuous operation on standard PCB traces |
| Dynamic Impedance ZZT | 1400 Ω at IZT = 250 mA - indicates regulation stiffness; lower values improve load regulation |
| Temp Coefficient αVZ | -0.075 %/°C - enables predictable voltage drift compensation in wide-temperature environments |
| Noise Density ND | 1 µV/√Hz at IZT = 250 mA - critical for low-noise analog references and sensor excitation |
| Max Reverse Current IR | 1.0 µA at VR = 1.0 V - ensures minimal leakage in standby or low-current bias networks |
| Junction Temp Range | -65 to +175 °C - supports deployment in aerospace, defense, and downhole electronics |
Pinout & Package
DO-35 (DO-204AH) axial-leaded hermetically sealed glass package; cathode indicated by band - banded end is positive during Zener regulation. Leads are tin-lead or RoHS-compliant matte-tin plated, solderable per MIL-STD-750 method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reverse-bias return path | Connected to system ground or lower-potential rail when regulating voltage at cathode |
| Cathode | Zener regulation output | Banded terminal; supplies stable 2.4 V reference when reverse-biased above breakdown |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/435 qualification | JAN-level screening ensures tested reliability for mission-critical systems without derating |
| Metallurgical bond construction | Eliminates interfacial delamination risk under thermal shock and vibration stress |
| 1% Zener voltage tolerance | Reduces need for post-production trimming in precision reference designs |
| Low noise density (1 µV/√Hz) | Enables use in high-resolution ADC references and low-noise op-amp biasing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JAN1N4617C-1 | Same 2.4 V nominal Zener voltage but 2% tolerance instead of 1% | Suitable where tighter voltage matching is not required for cost-sensitive military subsystems | Select JAN1N4617C-1 if ±2% regulation accuracy meets system error budget and reduces procurement cost |
| 1N4617US-1 | Same electrical specs but in surface-mount DO-213AA package instead of axial DO-35 | Required for automated SMT assembly or space-constrained board layouts | Select 1N4617US-1 only when reflow-compatible packaging and reduced board footprint are mandatory |
Compared with JAN1N4617D-1, JAN1N4617C-1 trades 1% tolerance for broader availability and lower cost, while 1N4617US-1 retains identical regulation performance but shifts to surface-mount form factor - neither offers pin-to-pin compatibility due to differing packages and reliability levels.

FAQ
What is the Zener voltage tolerance of JAN1N4617D-1?
JAN1N4617D-1 has a Zener voltage tolerance of ±1%, as indicated by the "D" suffix in its nomenclature. This means its nominal 2.4 V Zener voltage is guaranteed between 2.376 V and 2.424 V at 250 mA test current and 25 °C, supporting high-accuracy reference designs without post-calibration.
Is JAN1N4617D-1 suitable for high-temperature environments?
Yes, JAN1N4617D-1 is rated for junction temperatures from -65 to +175 °C and qualified to JAN level per MIL-PRF-19500/435. Its metallurgically bonded glass construction maintains stable Zener characteristics across this full range, making it appropriate for engine bay, downhole, or avionics applications.
What does the "JAN" prefix signify for JAN1N4617D-1?
The "JAN" prefix denotes Joint Army-Navy qualification - the lowest military reliability level in the MIL-PRF-19500/435 specification. JAN1N4617D-1 undergoes screening including temperature cycling, steady-state life testing, and visual inspection to ensure suitability for defense and aerospace use.
How is polarity marked on JAN1N4617D-1?
JAN1N4617D-1 uses a cathode band marking on the glass body - the banded end is the cathode and must be held at a higher potential than the anode to achieve Zener regulation. This marking is visible under standard optical inspection and complies with JEDEC standards for axial-leaded diodes.
Does JAN1N4617D-1 meet RoHS requirements?
No, JAN1N4617D-1 is not RoHS compliant. The "e3" suffix denotes RoHS compliance, which is only available on commercial-grade versions (e.g., 1N4617D-1e3). JAN-level parts use traditional tin-lead plating per MIL-STD-750 and are exempt from RoHS under defense procurement waivers.
