Product details
Overview
JAN1N4124C-1/TR from Microsemi is a 43 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.
For engineers reviewing the JAN1N4124C-1/TR datasheet, JAN1N4124C-1/TR pinout, JAN1N4124C-1/TR application, or JAN1N4124C-1/TR equivalent, key selection criteria include Zener voltage tolerance (±2%), noise density (1 µV/√Hz), dynamic impedance (250 Ω), junction temperature range (–65 °C to +175 °C), and MIL-qualified reliability level.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 43.0 V at 250 mA test current, exhibiting low noise density (1 µV/√Hz) and stable temperature coefficient (+0.095 %/°C). Its metallurgical bond construction ensures robust thermal performance and radiation hardness.
Designed for operation in the breakdown region, it maintains regulation across wide current ranges (IZK to IZM = 32.7 mA max) and supports stable reference generation under varying load and temperature conditions, with reverse leakage limited to 0.01 µA at VR = 34.4 V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4124US-1 | Same 43 V, 2% Zener voltage but in DO-213AA surface-mount package; no axial leads | Requires PCB re-layout for SMT assembly; unsuitable for through-hole prototyping or high-vibration mechanical mounting | Select when automated assembly, space constraints, or vibration resistance are prioritized over manual serviceability |

FAQ
What is the Zener voltage tolerance of JAN1N4124C-1/TR?
JAN1N4124C-1/TR has a Zener voltage tolerance of ±2%, indicated by the "C" suffix in its nomenclature. This means its nominal 43.0 V Zener voltage falls within 42.14 V to 43.86 V at IZT = 250 mA and 25 °C. The tolerance is guaranteed per MIL-PRF-19500/435 screening for JAN-level devices, making JAN1N4124C-1/TR suitable for precision reference applications where tighter regulation is required than standard ±5% parts.
Is JAN1N4124C-1/TR RoHS compliant?
No, JAN1N4124C-1/TR is not RoHS compliant. The "e3" RoHS designation appears only on commercial-grade versions (e.g., 1N4124C-1e3); JAN-level parts like JAN1N4124C-1/TR use traditional tin-lead plating per MIL-STD-750 and are exempt from RoHS requirements due to their military/aerospace qualification status. This ensures solderability and reliability in high-reliability assemblies where lead-free alternatives may introduce intermetallic growth risks.
What is the maximum Zener current IZM for JAN1N4124C-1/TR?
The maximum Zener current IZM for JAN1N4124C-1/TR is 32.7 mA, derived from its 500 mW power rating and 43.0 V Zener voltage (IZM = PM(AV)/VZ). This value assumes operation at 25 °C lead temperature; actual usable current must be linearly derated above 50 °C ambient per the published power derating curve. Exceeding IZM risks thermal runaway and permanent degradation of JAN1N4124C-1/TR.
Does JAN1N4124C-1/TR have radiation hardness?
Yes, JAN1N4124C-1/TR exhibits inherent radiation hardness as documented in Microsemi MicroNote 050. Its metallurgically bonded glass construction and DO-35 hermetic package provide tolerance to total ionizing dose (TID) exceeding 100 krad(Si) and resilience against single-event effects (SEE) common in space environments. This radiation performance is validated as part of its JAN qualification per MIL-PRF-19500/435, distinguishing JAN1N4124C-1/TR from commercial Zeners.
What does the "TR" suffix mean in JAN1N4124C-1/TR?
"TR" denotes tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. JAN1N4124C-1/TR contains the same die, qualification, and electrical specifications as JAN1N4124C-1, differing only in packaging format. Tape-and-reel ordering requires minimum quantities defined by Microsemi; the "TR" suffix does not affect reliability level, temperature range, or Zener characteristics of JAN1N4124C-1/TR.
