Product details
Overview
JAN1N4101-1/TR from Microsemi is a 500 mW, 8.2 V Zener voltage regulator diode in DO-35 (DO-204AH) axial-leaded glass package, qualified to JAN level per MIL-PRF-19500/435, with 5% voltage tolerance, 200 Ω dynamic impedance at 250 mA test current, and maximum reverse leakage of 0.5 µA at 6.3 V. It delivers stable voltage reference in high-reliability military power supply and analog signal conditioning circuits.
For engineers reviewing the JAN1N4101-1/TR datasheet, JAN1N4101-1/TR pinout, JAN1N4101-1/TR application, or JAN1N4101-1/TR equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (250 °C/W junction-to-lead), noise density (1 µV/√Hz), radiation hardness, and MIL-spec qualification level for aerospace and defense systems.
Technical Context
This device operates as a reverse-biased silicon Zener diode with metallurgically bonded construction, enabling stable regulation across wide current (250 mA IZT) and temperature (-65 to +175 °C) ranges. Its low 200 Ω dynamic impedance ensures minimal voltage variation under load transients.
The JAN1N4101-1/TR exhibits a positive temperature coefficient of +0.070 %/°C and nominal capacitance below 5 pF, supporting precision reference and low-noise analog applications where stability and minimal parasitic effects are critical.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4101US | Same 8.2 V Zener, DO-213AA surface-mount package; no MIL qualification; RoHS-compliant only | Lacks JAN-level screening and radiation hardness; suitable for commercial industrial boards with space constraints | Select when footprint reduction and lead-free compliance outweigh military reliability requirements |

FAQ
What is the Zener voltage and tolerance of JAN1N4101-1/TR?
JAN1N4101-1/TR has a nominal Zener voltage of 8.2 V at 250 mA test current with ±5% tolerance per JEDEC standard. This value is measured under thermal equilibrium at 25 °C ambient and applies to the JAN-level qualified version. The device maintains regulation within this band across its rated current and temperature range, making JAN1N4101-1/TR suitable for precision reference applications where MIL-spec consistency is required.
Is JAN1N4101-1/TR RoHS compliant?
No, JAN1N4101-1/TR is not RoHS compliant. RoHS-compliant versions (e.g., with e3 suffix) are available only for commercial-grade variants per the datasheet; JAN-level devices retain tin-lead plating to meet MIL-STD-750 solderability requirements and are exempt from RoHS restrictions under applicable defense exemptions. JAN1N4101-1/TR therefore retains legacy leaded finish for assured solder joint reliability in high-reliability assemblies.
What is the maximum power dissipation and derating behavior of JAN1N4101-1/TR?
JAN1N4101-1/TR has a rated average power dissipation of 500 mW at 25 °C lead temperature, linearly derated to zero at 175 °C. Derating begins at 50 °C for lead temperature or 25 °C for ambient on typical FR4 board layouts. Thermal resistance is 250 °C/W junction-to-lead (with 10 mm lead length) and 300 °C/W junction-to-ambient, defining heatsinking and layout constraints for sustained operation. These values are integral to safe thermal design using JAN1N4101-1/TR.
Does JAN1N4101-1/TR have radiation hardness certification?
Yes, JAN1N4101-1/TR is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgically bonded glass construction and process controls provide tolerance to total ionizing dose (TID) environments typical in space and nuclear applications. While not individually tested per MIL-STD-883, the family-level radiation performance is confirmed and leveraged in flight-certified systems-making JAN1N4101-1/TR a trusted choice where radiation-induced parameter shift must be minimized.
What does the "TR" suffix indicate in JAN1N4101-1/TR?
"TR" denotes tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. JAN1N4101-1/TR is supplied in industry-standard carrier tape with specified reel quantities and orientation (cathode band direction aligned per packaging spec). This format supports high-volume manufacturing while preserving JAN-level traceability and handling controls. The "TR" suffix does not affect electrical or reliability specifications-JAN1N4101-1/TR performs identically to bulk or ammo-pack versions.
