For engineers reviewing the JAN1N4101D-1 datasheet, JAN1N4101D-1 pinout, JAN1N4101D-1 application, or JAN1N4101D-1 equivalent, key selection criteria include its 1% Zener voltage tolerance, 250 mA Zener test current, 200 Ω dynamic impedance at IZT, low 0.5 µA reverse leakage at 6.3 V, and radiation-hardened hermetic construction suitable for harsh-environment analog reference and power-supply stabilization.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 8.2 V at 250 mA test current, exhibiting a +0.070 %/°C temperature coefficient and 200 Ω dynamic impedance (ZZT) under specified bias conditions. Its metallurgical bond ensures stable breakdown characteristics across wide temperature ranges.
Designed for military-grade reliability, JAN1N4101D-1 meets JANS qualification per MIL-PRF-19500/435, supports operation from –65 °C to +175 °C junction temperature, and delivers minimal capacitance (<2 pF typical) and low noise density (≤1 µV/√Hz below 6.8 V), making it suitable for low-noise reference circuits.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4101D-1 | Same electrical specs but qualified to JANTXV level (enhanced screening vs. JANS); higher cost, shorter lead time. | Preferred for non-space defense programs requiring accelerated life testing but not full radiation assurance. | Select when full JANS qualification is unnecessary and faster procurement is prioritized over ultimate radiation hardness. |
| 1N4101UR-1 | Surface-mount DO-213AA variant; identical Zener parameters but different thermal resistance (RθJA = 400 °C/W vs. 300 °C/W). | Suitable for automated assembly and space-constrained PCBs where axial leads are incompatible with layout. | Choose for modern SMT production lines; derate power by 20% due to higher thermal resistance versus DO-35. |
Compared with JAN1N4101D-1, JANTXV1N4101D-1 offers faster availability with slightly less rigorous radiation testing, while 1N4101UR-1 enables PCB miniaturization at the cost of reduced thermal performance and absence of JANS-level reliability documentation.

FAQ
What is the Zener voltage tolerance of JAN1N4101D-1?
JAN1N4101D-1 has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its nomenclature. This means its nominal 8.2 V Zener voltage is guaranteed between 8.118 V and 8.282 V at 250 mA test current and 25 °C ambient, supporting high-accuracy reference design without post-manufacture trimming.
Is JAN1N4101D-1 suitable for space applications?
Yes, JAN1N4101D-1 is qualified to JANS level per MIL-PRF-19500/435, including full radiation hardness assurance per Microsemi MicroNote 050. It is approved for Class S (space) applications and supports total ionizing dose (TID) levels up to 100 krad(Si), making it appropriate for satellite power and telemetry subsystems.
What is the maximum reverse leakage current for JAN1N4101D-1?
The maximum reverse leakage current (IR) for JAN1N4101D-1 is 0.5 µA at VR = 6.3 V and 25 °C. This ultra-low leakage ensures minimal loading on high-impedance reference nodes and supports energy-efficient operation in battery-backed monitoring circuits.
Does JAN1N4101D-1 require heatsinking in standard operation?
No, JAN1N4101D-1 does not require external heatsinking at 500 mW dissipation under standard conditions (TC = 25 °C). Its DO-35 package has RθJL = 250 °C/W with 10 mm lead length, allowing direct mounting on FR4 PCBs with 4 mm² copper pads-derating begins linearly above 50 °C lead temperature.
How does the temperature coefficient of JAN1N4101D-1 affect system accuracy?
JAN1N4101D-1 has a temperature coefficient of +0.070 %/°C, meaning its Zener voltage increases by approximately 5.74 mV per °C rise. In a –55 °C to +125 °C range, this contributes ±12.6 mV drift, which must be accounted for in high-precision reference designs-often mitigated via complementary TC components or calibration.
