Product details
Overview
JANS1N4115-1/TR from Microsemi is a 500 mW, 22.0 V ±5% metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense applications. It delivers stable voltage regulation with 150 Ω dynamic impedance at 250 mA test current, 0.01 µA max reverse leakage at 17.6 V, and +0.090 %/°C temperature coefficient.
For engineers reviewing the JANS1N4115-1/TR datasheet, JANS1N4115-1/TR pinout, JANS1N4115-1/TR application, or JANS1N4115-1/TR equivalent, key selection criteria include Zener voltage tolerance, radiation hardness, thermal resistance (250 °C/W junction-to-lead), noise density (≤1 µV/√Hz), and compliance with MIL-PRF-19500/435 JANS screening requirements.
Technical Context
This device operates as a precision shunt voltage regulator in reverse-biased breakdown mode, with cathode band marking polarity. Its metallurgical bond construction ensures mechanical stability under thermal cycling and shock, while hermetic glass sealing provides immunity to humidity and contaminants.
Designed for operation across –65 °C to +175 °C junction temperature range, it supports linear power derating from 500 mW at 25 °C ambient to zero at 175 °C, and exhibits minimal capacitance (<2 pF typical at 22 V) and low noise density critical for reference and sensing circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 22.0 V ±5% at 250 mA - defines nominal regulation point with tight tolerance for precision references |
| Power Dissipation | 500 mW @ TL = 25 °C - sets maximum continuous DC power handling before thermal derating begins |
| Dynamic Impedance ZZT | 150 Ω @ IZT = 250 mA - determines output voltage variation under load current changes |
| Reverse Leakage IR | 0.01 µA @ VR = 17.6 V - ensures negligible error current in high-impedance bias networks |
| Temp Coefficient αVZ | +0.090 %/°C - quantifies drift magnitude over temperature for stability-critical designs |
| Noise Density ND | ≤1 µV/√Hz @ IZT - enables low-noise voltage references in analog signal chains |
| Junction Temp Range | –65 °C to +175 °C - supports operation in extreme environmental conditions without parameter shift |
Pinout & Package
Package: DO-35 (DO-204AH), axial-leaded, hermetically sealed glass case with tin-lead plating; cathode indicated by single black band; weight ≈0.2 g.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4115-1 | Same electrical specs but qualified to JANTXV level (less stringent screening than JANS); RθJL = 250 °C/W identical | Approved for high-reliability industrial and avionics programs where full JANS screening is not mandated | Select when cost sensitivity outweighs need for full space-grade qualification |
| 1N4115US-1 | Same 22 V Zener voltage but in surface-mount DO-213AA package; thermal resistance RθJA = 300 °C/W vs. 250 °C/W for leaded version | Used in compact PCB layouts requiring automated assembly; lacks JANS qualification | Select only for commercial or industrial applications where hermeticity and radiation tolerance are not required |
Compared with JANS1N4115-1/TR, JANTXV1N4115-1 offers identical regulation performance with reduced screening cost, while 1N4115US-1 trades JANS qualification and thermal performance for SMT compatibility-neither is pin-compatible due to differing packages and qualification levels.

FAQ
What is the Zener voltage tolerance for JANS1N4115-1/TR?
JANS1N4115-1/TR has a nominal Zener voltage of 22.0 V with a ±5% tolerance, as defined by JEDEC standard and verified per MIL-PRF-19500/435 JANS screening. This tolerance applies at 250 mA test current and 25 °C ambient temperature, and remains stable across its full operating temperature range due to its +0.090 %/°C temperature coefficient.
Is JANS1N4115-1/TR radiation hardened?
Yes, JANS1N4115-1/TR is inherently radiation tolerant as documented in Microsemi MicroNote 050. It is qualified to JANS level per MIL-PRF-19500/435 and rated for total ionizing dose (TID) up to 100 krad(Si) without functional degradation or parameter shift, making it suitable for satellite and nuclear instrumentation applications.
What is the thermal resistance specification for JANS1N4115-1/TR?
JANS1N4115-1/TR has a junction-to-lead thermal resistance (RθJL) of 250 °C/W when mounted with 3/8 inch (10 mm) lead length from body, and a junction-to-ambient resistance (RθJA) of 300 °C/W on FR4 board with specified copper pad geometry. These values govern its power derating curve from 500 mW at 25 °C to zero at 175 °C.
Does JANS1N4115-1/TR have RoHS compliance?
No, JANS1N4115-1/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (suffix e3) are available only for commercial-grade variants (e.g., 1N4115-1e3). The JANS-level qualification requires tin-lead plating for solderability and reliability validation under MIL-STD-750, which is exempt from RoHS restrictions.
What is the maximum reverse leakage current for JANS1N4115-1/TR?
The maximum reverse leakage current (IR) for JANS1N4115-1/TR is 0.01 µA measured at VR = 17.6 V (80% of nominal Zener voltage), per Electrical Characteristics table on page 3 of T4-LDS-0245-2. This ultra-low leakage ensures minimal error in high-impedance reference and bias networks.
