Product details
Overview
JAN1N4105C-1 from Microsemi is a 500 mW, 11.0 V Zener voltage regulator diode in DO-35 glass package, qualified to JANS level per MIL-PRF-19500/435, with 2% voltage tolerance, 200 Ω dynamic impedance at 250 mA test current, and +0.080 %/°C temperature coefficient - used for precision voltage reference in military-grade power supply regulation.
For engineers reviewing the JAN1N4105C-1 datasheet, JAN1N4105C-1 pinout, JAN1N4105C-1 application, or JAN1N4105C-1 equivalent, key selection factors include Zener voltage accuracy (±2%), low noise density (1 μV/√Hz), hermetic glass packaging, radiation hardness, and MIL-spec qualification level - critical for high-reliability analog reference design.
Technical Context
This device operates as a reverse-biased Zener regulator with metallurgically bonded junction, delivering stable 11.0 V output across 5–40 mA operating current range. Its low dynamic impedance (200 Ω) and tight ±2% tolerance ensure minimal regulation error under load and temperature variation.
The JAN1N4105C-1 exhibits +0.080 %/°C temperature coefficient and 1 μV/√Hz noise density at 11 V, confirming suitability for low-drift, low-noise analog references. It is rated for junction temperatures from –65 °C to +175 °C and supports linear derating from 500 mW at 25 °C to zero at 175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 11.0 V at 250 mA - defines precise regulation point for reference circuits |
| Voltage Tolerance | ±2% - enables tighter system-level voltage margin control vs. standard ±5% |
| Power Rating | 500 mW - supports stable operation up to 45.5 mA at 11 V without thermal runaway |
| Dynamic Impedance ZZT | 200 Ω - ensures <110 mV output shift per 55 mA load change |
| Temp Coefficient αVZ | +0.080 %/°C - contributes ~8.8 mV/°C drift, manageable with compensation |
| Noise Density | 1 μV/√Hz - minimizes added noise in precision analog signal chains |
| Reverse Leakage IR | 0.05 µA @ 8.8 V - ensures negligible current draw in standby reference mode |
Pinout & Package
DO-35 (DO-204AH) axial-leaded hermetically sealed glass package; cathode indicated by band; banded end is anode when used in forward bias, but functions as cathode (positive terminal) during Zener regulation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (banded end) | Zener cathode connection | Connected to regulated output node; must be held at higher potential than cathode for breakdown conduction |
| Cathode (non-banded end) | Zener anode connection | Connected to circuit ground or lower-potential rail; completes reverse-bias path for regulation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4105US-1 | Same electrical specs, but in DO-213AA surface-mount package - no axial leads | Used where PCB real estate or automated assembly requires SMT instead of through-hole | Select when board layout mandates SMT; same regulation performance but different thermal path and mounting |
| JANTXV1N4105C-1 | Identical Zener parameters and 2% tolerance, but qualified to JANTXV level - lower screening rigor than JANS | Suitable for high-reliability ground-based systems where full JANS radiation testing is not required | Select for cost-sensitive defense programs needing MIL-spec assurance without full space-grade screening |
Compared with JAN1N4105C-1, the 1N4105US-1 offers identical regulation performance in a surface-mount form factor, while JANTXV1N4105C-1 provides matching electrical behavior with reduced qualification scope - enabling trade-offs between radiation hardness, assembly method, and procurement cost.

FAQ
What is the Zener voltage and tolerance of JAN1N4105C-1?
JAN1N4105C-1 has a nominal Zener voltage of 11.0 V with a ±2% tolerance, measured at 250 mA test current and 25 °C ambient. This tolerance is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1, and applies strictly to the JAN1N4105C-1 variant due to the "C" suffix denoting 2% tolerance per the nomenclature guide.
Is JAN1N4105C-1 qualified to JANS level per MIL-PRF-19500/435?
Yes, JAN1N4105C-1 is qualified to JANS level per MIL-PRF-19500/435, as stated in the DESCRIPTION section on page 1 of T4-LDS-0245-2 Rev. 1. The "JAN" prefix explicitly denotes the highest reliability level, and the datasheet confirms JANS qualification is available for the entire 1N4099-1 through 1N4135-1 series including JAN1N4105C-1.
What is the maximum power dissipation and derating behavior of JAN1N4105C-1?
JAN1N4105C-1 has a rated average power dissipation of 0.5 W at 25 °C, linearly derated to zero at 175 °C per Figure 2. Derating begins at 50 °C for lead temperature or 25 °C for ambient conditions on a typical FR4 board - meaning usable power drops to ~375 mW at 75 °C ambient, ensuring safe operation in high-temperature enclosures.
Does JAN1N4105C-1 have radiation hardness, and is it ESD-sensitive?
JAN1N4105C-1 is inherently radiation hard per Microsemi MicroNote 050 and non-sensitive to ESD per MIL-STD-750 Method 1020. These attributes are explicitly listed in the APPLICATIONS / BENEFITS section on page 1 of T4-LDS-0245-2 Rev. 1, making JAN1N4105C-1 suitable for high-radiation environments without additional shielding or protection circuits.
What package type and marking does JAN1N4105C-1 use?
JAN1N4105C-1 uses the DO-35 (DO-204AH) axial-leaded hermetically sealed glass package, with polarity indicated by a cathode band. The device is marked with its full part number "JAN1N4105C-1", as specified in the MECHANICAL and PACKAGING section on page 2 of T4-LDS-0245-2 Rev. 1.
