Product details
Overview
JAN1N4615C-1/TR from Microsemi is a 2.0 V, 2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JAN level per MIL-PRF-19500/435 for high-reliability voltage regulation in military and aerospace power supplies, reference circuits, and overvoltage protection.
For engineers reviewing the JAN1N4615C-1/TR datasheet, JAN1N4615C-1/TR pinout, JAN1N4615C-1/TR application, or JAN1N4615C-1/TR equivalent, key selection factors include its 2.0 V nominal Zener voltage at 250 mA test current, 1250 Ω maximum dynamic impedance, -0.075 %/°C temperature coefficient, and hermetically sealed axial-leaded construction for stable operation across -65 °C to +175 °C.
Technical Context
This Zener diode operates in reverse breakdown with cathode-banded polarity, delivering precise voltage regulation under varying load and temperature conditions. Its internal metallurgical bond ensures low noise density (1 µV/√Hz) and minimal capacitance, critical for low-drift analog references.
Designed for DC regulation only, it exhibits a sharp knee at IZK = 250 mA and supports linear derating from 500 mW at 25 °C to zero at 175 °C. Thermal resistance junction-to-lead is 250 °C/W with 10 mm lead length, enabling reliable thermal management in through-hole PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 2.0 V at 250 mA - defines regulated output voltage under standard test conditions |
| Zener Tolerance | ±2% - tighter than standard 5% parts, enabling higher-precision reference designs |
| Power Dissipation | 500 mW - supports stable regulation in compact axial-leaded packages without forced cooling |
| Dynamic Impedance | 1250 Ω max - limits output voltage variation under changing load current |
| Temp Coefficient | -0.075 %/°C - predictable negative drift enables compensation in temperature-critical circuits |
| Noise Density | 1 µV/√Hz - ultra-low broadband noise suitable for precision analog references |
| Max Reverse Current | 2.5 µA at 1.0 V - ensures minimal leakage below breakdown threshold |
Pinout & Package
DO-35 (DO-204AH) hermetically sealed axial-leaded glass package with tin-lead plating; cathode indicated by band; weight ≈ 0.2 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Reference ground node | Connected to circuit common; reverse-biased operation requires this terminal at lower potential |
| Cathode (banded end) | Regulated output node | Provides stable 2.0 V output when reverse-biased; must be held positive relative to anode |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JAN1N4615-1/TR | Same 2.0 V Zener voltage and DO-35 package, but ±5% tolerance instead of ±2% | Acceptable where cost sensitivity outweighs precision requirement; not suitable for Class-S or Class-B avionics | Select JAN1N4615C-1/TR when ±2% tolerance is mandated by system specification or calibration procedure |
| JANTXV1N4615C-1/TR | Identical electrical specs and tolerance, but qualified to JANTXV level with enhanced screening (burn-in, thermal shock, life test) | Required for space-qualified subsystems or programs demanding extended reliability validation beyond JAN level | Choose JANTXV1N4615C-1/TR when mission-critical redundancy or 10+ year shelf life is specified |
Compared with JAN1N4615-1/TR, JAN1N4615C-1/TR delivers tighter voltage control essential for high-accuracy references, while JANTXV1N4615C-1/TR adds process-level reliability assurance for extreme environment deployment-neither is pin-compatible with commercial 1N4615C-1/TR due to differing qualification markings and traceability requirements.

FAQ
What is the Zener voltage and test current for JAN1N4615C-1/TR?
JAN1N4615C-1/TR has a nominal Zener voltage of 2.0 V measured at a test current (IZT) of 250 mA. This value is guaranteed within ±2% tolerance across the qualified temperature range and forms the basis for all regulation performance specifications in the official Microsemi datasheet T4-LDS-0245-2.
Is JAN1N4615C-1/TR RoHS compliant?
No, JAN1N4615C-1/TR is not RoHS compliant. The "e3" RoHS suffix is only available on commercial-grade versions per the nomenclature table; JAN-level parts use tin-lead plating to meet MIL-STD-750 solderability requirements and are exempt from RoHS restrictions under defense procurement regulations.
What does the "C" in JAN1N4615C-1/TR signify?
The "C" in JAN1N4615C-1/TR indicates ±2% Zener voltage tolerance, as defined in the Microsemi part nomenclature guide. It distinguishes this variant from the standard ±5% version (JAN1N4615-1/TR) and the ±1% version (JAN1N4615D-1/TR), enabling precise selection for tight-regulation applications.
What is the maximum power dissipation and derating behavior of JAN1N4615C-1/TR?
JAN1N4615C-1/TR has a rated average power dissipation of 500 mW at 25 °C, linearly derated to zero at 175 °C. Derating begins at 50 °C for lead temperature or 25 °C for ambient conditions on a typical FR4 board, per Figure 2 in the T4-LDS-0245-2 datasheet.
Does JAN1N4615C-1/TR require heatsinking in standard PCB layouts?
No additional heatsinking is required for JAN1N4615C-1/TR in standard through-hole layouts. With thermal resistance junction-to-lead of 250 °C/W and junction-to-ambient of 300 °C/W on FR4 (1 oz Cu, 4 mm² pads), it safely dissipates 500 mW at room temperature without exceeding the 175 °C maximum junction temperature.
