Product details
Overview
JAN1N4615D-1 from Microsemi is a 500 mW, 2.0 V Zener voltage regulator diode in DO-35 glass axial-leaded package, qualified to JANS level per MIL-PRF-19500/435, with 1% voltage tolerance, 250 mA test current, and 1250 Ω dynamic impedance - used for precision voltage reference and regulation in military-grade power supply circuits.
For engineers reviewing the JAN1N4615D-1 datasheet, JAN1N4615D-1 pinout, JAN1N4615D-1 application, or JAN1N4615D-1 equivalent, key selection criteria include Zener voltage accuracy (±1%), low noise density (1 µV/√Hz), hermetic DO-35 packaging, MIL-qualified reliability, and thermal resistance (250 °C/W junction-to-lead).
Technical Context
This device operates as a reverse-biased Zener regulator with metallurgically bonded construction for enhanced stability and radiation hardness. It maintains regulation across wide current (250 mA IZT) and temperature (-65 to +175 °C) ranges while delivering low noise density (1 µV/√Hz) and tight voltage tolerance (±1%).
The JAN1N4615D-1 exhibits a negative temperature coefficient of -0.075 %/°C and is rated for 500 mW average power dissipation at 25 °C, derating linearly to zero at 175 °C. Its DO-35 package supports axial mounting with cathode band polarity marking and tin-lead or RoHS-compliant matte-tin plating.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JAN1N4615C-1 | Same 2.0 V nominal Zener voltage but ±2% tolerance instead of ±1%. | Acceptable where tighter regulation is not required; lower cost for non-critical references. | Select JAN1N4615C-1 if system-level calibration compensates for initial tolerance. |
| 1N4615US-1 | Same electrical specs but in surface-mount DO-213AA package (no axial leads). | Used in automated SMT assembly; requires reflow-compatible layout and lacks axial mounting flexibility. | Choose 1N4615US-1 only when board space constraints mandate SMT and JANS qualification is not required. |
Compared with JAN1N4615D-1, JAN1N4615C-1 trades 1% accuracy for broader tolerance and lower cost, while 1N4615US-1 replaces axial DO-35 with surface-mount DO-213AA - neither offers JANS qualification or identical mechanical mounting, making JAN1N4615D-1 irreplaceable for legacy mil-spec through-hole designs requiring highest reliability.

FAQ
What is the Zener voltage tolerance of JAN1N4615D-1?
JAN1N4615D-1 has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its nomenclature. This tight tolerance ensures highly accurate 2.0 V regulation at 250 mA test current, making it suitable for precision reference applications where post-calibration is impractical or prohibited.
Is JAN1N4615D-1 qualified to JANS level?
Yes, JAN1N4615D-1 is qualified to JANS level per MIL-PRF-19500/435, the highest reliability grade for microelectronic devices. This qualification includes rigorous testing for temperature cycling, mechanical shock, vibration, and long-term life reliability - confirmed in Microsemi's T4-LDS-0245-2 datasheet.
What is the maximum power dissipation for JAN1N4615D-1 at 100 °C lead temperature?
At 100 °C lead temperature, JAN1N4615D-1's rated average power dissipation is linearly derated from 500 mW at 25 °C. Using the specified derating slope (500 mW → 0 W over 150 °C), power at 100 °C is approximately 250 mW - consistent with Figure 2 in the official datasheet.
Does JAN1N4615D-1 have radiation hardness specifications?
Yes, JAN1N4615D-1 is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgically bonded construction and hermetic DO-35 package provide proven resilience to total ionizing dose (TID), making it suitable for space and nuclear environments without additional shielding.
What does the "-1" suffix indicate in JAN1N4615D-1?
The "-1" suffix in JAN1N4615D-1 indicates compliance with the original JEDEC-registered 1N4615 specification and confirms adherence to the electrical, mechanical, and qualification requirements defined in Microsemi's T4-LDS-0245-2 datasheet - distinguishing it from commercial variants or non-qualified equivalents.
