Product details
Overview
JAN1N4619D-1 from Microsemi is a 500 mW, 3.0 V ±1% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JAN1N4619D-1 datasheet, JAN1N4619D-1 pinout, JAN1N4619D-1 application, or JAN1N4619D-1 equivalent, key selection criteria include its 1% Zener voltage tolerance, 250 mA test current, 1600 Ω dynamic impedance at IZT, low noise density (1 µV/√Hz), and JANS-level radiation hardness and thermal stability.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 3.0 V at 250 mA test current, exhibiting a temperature coefficient of −0.075 %/°C and maximum reverse leakage of 1.0 µA at 2.4 V. Its metallurgical bond construction ensures stable junction behavior under thermal cycling and radiation exposure.
The JAN1N4619D-1 is rated for 500 mW average power dissipation at 25 °C, derating linearly to zero at 175 °C, with thermal resistance junction-to-lead of 250 °C/W at 10 mm lead length. It delivers low capacitance (typical <2 pF at 0 V) and ESD immunity per MIL-STD-750 method 1020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.0 V ±1% at 250 mA - enables precise 3.0 V reference generation with tight tolerance for analog sensing and calibration circuits. |
| Power Dissipation (PM(AV)) | 500 mW at 25 °C - supports stable regulation in compact through-hole designs without forced cooling. |
| Dynamic Impedance (ZZT) | 1600 Ω at 250 mA - indicates moderate regulation stiffness; suitable for low-current biasing and reference applications, not high-ripple suppression. |
| Noise Density (ND) | 1 µV/√Hz at 250 mA - ultra-low broadband noise ideal for precision analog references and low-noise instrumentation front-ends. |
| Temp. Coefficient (αVZ) | −0.075 %/°C - predictable negative drift allows compensation in temperature-critical voltage references. |
| Reverse Leakage (IR) | 1.0 µA max at 2.4 V - ensures minimal quiescent current draw in battery-powered or low-power standby circuits. |
| Package | DO-35 (DO-204AH) - hermetically sealed axial-glass package with tin-lead plating, qualified for military environments and long-term reliability. |
Pinout & Package
DO-35 (DO-204AH) hermetically sealed axial-leaded glass package. Cathode indicated by band; operated with banded end positive relative to anode for Zener regulation. Weight ≈ 0.2 g. Dimensions: body diameter 1.42–2.29 mm, body length 3.56–5.08 mm, lead length 25.4–38.1 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Reference ground node | Connected to circuit common; establishes return path for Zener current and defines regulated output polarity. |
| Cathode (banded end) | Regulated voltage output | Provides stable 3.0 V output when reverse-biased; must be held at higher potential than anode during regulation. |
Key Features
| Feature | Design Value |
|---|---|
| Metallurgical bond construction | Ensures mechanical and thermal stability of the PN junction under shock, vibration, and thermal cycling-critical for aerospace avionics. |
| JANS qualification per MIL-PRF-19500/435 | Validated for space-grade reliability including radiation hardness (per MicroNote 050), extended temperature range (−65 to +175 °C), and lot traceability. |
| 1% Zener voltage tolerance | Reduces need for post-assembly trimming in precision reference designs, improving yield and long-term stability in mission-critical systems. |
| Low noise density (1 µV/√Hz) | Enables use in high-resolution ADC references and low-noise op-amp bias networks where voltage noise directly impacts SNR. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4619US-1 | Same electrical specs but in surface-mount DO-213AA package; no axial leads. | Used where PCB real estate is constrained and reflow assembly is required; lacks axial mounting flexibility. | Select when transitioning from through-hole to SMT production or when board space is limited. |
| JANTXV1N4619D-1 | Identical Zener parameters and 1% tolerance, but qualified only to JANTXV level (not JANS); lower screening rigor and no radiation hardness validation. | Suitable for high-reliability ground-based systems where full JANS radiation testing is unnecessary. | Choose for cost-sensitive defense programs requiring high reliability but not space qualification. |
Compared with JAN1N4619D-1, the 1N4619US-1 offers identical regulation performance in a smaller footprint but sacrifices axial mounting and manual repairability, while JANTXV1N4619D-1 reduces cost and test overhead at the expense of radiation tolerance and extreme-environment validation.

FAQ
What is the Zener voltage tolerance and test current for JAN1N4619D-1?
JAN1N4619D-1 has a nominal Zener voltage of 3.0 V with ±1% tolerance, measured at a Zener test current (IZT) of 250 mA. This tight tolerance is achieved via post-process binning and verified during JANS qualification testing per MIL-PRF-19500/435.
Is JAN1N4619D-1 suitable for space applications?
Yes, JAN1N4619D-1 is qualified to JANS level per MIL-PRF-19500/435 and exhibits inherent radiation hardness per Microsemi MicroNote 050. Its hermetic DO-35 package, metallurgical bond construction, and full lot traceability make it approved for use in LEO and GEO satellite power and sensor subsystems.
What is the maximum power dissipation and derating behavior of JAN1N4619D-1?
JAN1N4619D-1 is rated for 500 mW average power dissipation at 25 °C ambient, with linear derating beginning at 50 °C case temperature and reaching zero at 175 °C. On a standard FR4 board with 4 mm² copper pads, thermal resistance junction-to-ambient is 300 °C/W.
Does JAN1N4619D-1 have low-noise characteristics, and how is that specified?
Yes, JAN1N4619D-1 has a maximum noise density of 1 µV/√Hz at 250 mA, measured in the 1–3 kHz band using a standardized circuit (Figure 1). This ultra-low noise supports high-precision analog references where voltage noise directly limits system resolution.
How is polarity marked and configured for regulation on JAN1N4619D-1?
JAN1N4619D-1 uses a cathode band to indicate polarity: the banded end is the cathode and must be held at a higher potential than the unbanded (anode) end to operate in Zener breakdown. Reverse biasing this configuration provides 3.0 V regulation at the cathode terminal relative to system ground.
