Product details
Overview
JAN1N4116C-1/TR from Microsemi is a 24 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 aerospace and defense power supplies, reference circuits, and overvoltage protection.
For engineers reviewing the JAN1N4116C-1/TR datasheet, JAN1N4116C-1/TR pinout, JAN1N4116C-1/TR application, or JAN1N4116C-1/TR equivalent, key selection criteria include Zener voltage tolerance (2%), noise density (1 µV/√Hz), dynamic impedance (150 Ω), temperature coefficient (+0.090 %/°C), and military-grade qualification level.
Technical Context
This Zener diode operates in reverse breakdown with cathode-banded polarity, delivering stable 24 V regulation across 250 mA test current and wide temperature range (–65 °C to +175 °C). Its metallurgical bond ensures low leakage and radiation hardness per MicroNote 050.
Designed for precision reference use, it exhibits minimal capacitance (typ. <2 pF at 24 V) and low noise density-1 µV/√Hz at 24 V-enabling clean analog references in sensitive instrumentation and telemetry systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 24.0 V ±2% at 250 mA - precise regulation point for mid-range voltage references |
| Power Dissipation | 500 mW @ 25 °C - supports continuous operation in compact, unheatsinked designs |
| Dynamic Impedance ZZT | 150 Ω max at 250 mA - low AC impedance ensures stable regulation under varying load |
| Noise Density | 1 µV/√Hz @ 24 V - ultra-low broadband noise critical for precision analog references |
| Temp. Coefficient αVZ | +0.090 %/°C - predictable positive drift enables accurate thermal compensation |
| Reverse Leakage IR | 0.01 µA @ 18.3 V - negligible current loss in high-impedance bias networks |
| Max Regulator Current IZM | 40 mA - defines safe DC operating limit before thermal derating begins |
Pinout & Package

Use Value: Inherent radiation hardness (per MicroNote 050) eliminates need for shielding or redundancy in high-dose environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4116US-1 | Same 24 V, 2% spec, but in DO-213AA surface-mount package; no axial leads | Used where board space is constrained and reflow assembly required | Select when transitioning from through-hole to SMT without changing circuit topology |
| JANTXV1N4116C-1 | Identical electrical specs; qualified to JANTXV level (higher screening than JAN) | Required for programs demanding extended burn-in, lot acceptance testing, and enhanced traceability | Select when full JANTXV compliance is mandated by system specification |
Compared with JAN1N4116C-1/TR, 1N4116US-1 offers identical regulation performance in a space-saving SMT form factor, while JANTXV1N4116C-1 adds rigorous screening for mission-critical platforms-neither is pin-compatible due to differing packages, but both maintain identical Zener characteristics and thermal behavior.

FAQ
What is the Zener voltage tolerance of JAN1N4116C-1/TR?
JAN1N4116C-1/TR has a nominal Zener voltage of 24.0 V with a tolerance of ±2%, indicated by the "C" suffix in the part number per Microsemi's nomenclature. This tighter tolerance reduces calibration overhead in precision reference designs compared to standard 5% variants like JAN1N4116-1.
Is JAN1N4116C-1/TR RoHS compliant?
No, JAN1N4116C-1/TR is not RoHS compliant. The "e3" suffix denotes RoHS compliance, which is only available on commercial-grade versions-not JAN-level qualified parts. JAN1N4116C-1/TR uses traditional tin-lead plating per MIL-STD-750, method 2026.
What is the maximum Zener test current for JAN1N4116C-1/TR?
The maximum Zener test current IZT for JAN1N4116C-1/TR is 250 mA, as specified in Microsemi's T4-LDS-0245-2 datasheet. This current defines the operating point at which VZ, ZZT, and noise density are measured and guaranteed.
Does JAN1N4116C-1/TR have radiation hardness certification?
Yes, JAN1N4116C-1/TR is inherently radiation hard per Microsemi MicroNote 050. Its metallurgically bonded construction and hermetic DO-35 package provide proven resilience to total ionizing dose (TID) up to 100 krad(Si), making it suitable for space and nuclear environments.
What does the "TR" suffix mean in JAN1N4116C-1/TR?
The "TR" suffix indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. JAN1N4116C-1/TR is supplied in reels containing standard quantities-consult Aetrix Electronics for exact reel size and quantity options.
