Product details
Overview
JANTXV1N4101-1 from Microsemi is a 500 mW, 8.2 V ±5% metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation. It delivers stable reference voltage across wide current (250 mA test) and temperature (−65 °C to +175 °C) ranges, with low dynamic impedance (200 Ω) and minimal noise density (1 µV/√Hz), used in precision power supply feedback and analog reference circuits.
For engineers reviewing the JANTXV1N4101-1 datasheet, JANTXV1N4101-1 pinout, JANTXV1N4101-1 application, or JANTXV1N4101-1 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (250 °C/W junction-to-lead), radiation hardness, MIL-spec qualification level, and axial-leaded DO-35 mechanical compatibility in harsh-environment designs.
Technical Context
This device operates as a reverse-biased voltage reference with a nominal Zener voltage of 8.2 V at 250 mA test current, exhibiting a positive temperature coefficient (+0.070 %/°C) and low dynamic impedance (200 Ω at IZT). Its metallurgical bond construction ensures long-term stability under thermal cycling and radiation exposure.
Designed for high-reliability applications, JANTXV1N4101-1 meets MIL-PRF-19500/435 requirements for JANTXV screening, including hermetic glass sealing, non-ESD-sensitive behavior per MIL-STD-750 Method 1020, and operation over −65 °C to +175 °C junction temperature range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4101US (Microchip) | Same 8.2 V rating and DO-35 package but commercial-grade only; no MIL qualification or JANTXV screening | Lacks radiation hardness, extended temperature validation, and hermetic seal verification required for aerospace use | Select only for cost-sensitive industrial prototypes where MIL-spec compliance is not mandated |
| JANTXV1N4102-1 (Microsemi) | 8.7 V nominal Zener voltage; identical JANTXV qualification, DO-35 package, and thermal specs | Used where slightly higher reference voltage improves noise margin in comparator-based protection circuits | Choose when system architecture requires 8.7 V threshold instead of 8.2 V-same reliability, same footprint |
Compared with JANTXV1N4101-1, the 1N4101US offers lower cost but omits military screening and radiation assurance, while JANTXV1N4102-1 provides a direct form-fit-function alternative with adjusted voltage for specific threshold needs-neither is pin-compatible drop-in replacement due to voltage mismatch.

FAQ
What is the Zener voltage tolerance for JANTXV1N4101-1?
JANTXV1N4101-1 has a nominal Zener voltage of 8.2 V with ±5% tolerance, consistent with the standard JEDEC specification for the 1N4101-1 series. This tolerance is measured at 250 mA test current and 25 °C ambient, and applies across the full JANTXV qualification temperature range (−65 °C to +175 °C junction).
Is JANTXV1N4101-1 suitable for high-temperature downhole applications?
Yes, JANTXV1N4101-1 is rated for junction temperatures from −65 °C to +175 °C and is routinely deployed in oil/gas downhole tools. Its metallurgically bonded glass construction and hermetic DO-35 package ensure parameter stability and leakage immunity at sustained 175 °C, with no derating required below that limit.
Does JANTXV1N4101-1 meet RoHS requirements?
No-JANTXV1N4101-1 is a military-grade part with tin-lead plating per MIL-STD-750 and is not RoHS compliant. RoHS-compliant versions (e.g., with matte-tin plating) are available only in commercial-grade variants such as 1N4101-1e3, not in JANTXV configuration.
What is the maximum Zener current IZM for JANTXV1N4101-1?
The maximum Zener current IZM for JANTXV1N4101-1 is 40 mA, derived from its 500 mW power rating and 8.2 V Zener voltage (P = V × I → I = 0.5 W / 8.2 V ≈ 61 mA, but datasheet specifies 40 mA absolute max to ensure safe operation within thermal limits and reliability margins).
How does the temperature coefficient of JANTXV1N4101-1 affect circuit design?
JANTXV1N4101-1 has a temperature coefficient of +0.070 %/°C, meaning its Zener voltage increases ~5.7 mV/°C. This predictable positive drift allows designers to compensate adjacent circuitry (e.g., using negative-TC resistors) or select complementary devices in multi-reference systems to achieve net-zero drift.
