Product details
Overview
JANTX1N4133C-1 from Microsemi is a 500 mW, 87 V Zener diode in DO-35 glass package with ±2% voltage tolerance, metallurgically bonded construction, and MIL-PRF-19500/435 JANTX qualification for high-reliability voltage regulation in aerospace power supplies.
For engineers reviewing the JANTX1N4133C-1 datasheet, JANTX1N4133C-1 pinout, JANTX1N4133C-1 application, or JANTX1N4133C-1 equivalent, key selection criteria include Zener voltage (87 V), test current (250 mA), dynamic impedance (1000 Ω), noise density (1 µV/√Hz), and JANTX-level radiation-hardened reliability for mission-critical analog reference circuits.
Technical Context
This device operates as a precision shunt voltage regulator in reverse-biased breakdown mode, with cathode-band polarity marking and thermal derating from 500 mW at 25 °C to zero at 175 °C. Its metallurgical bond ensures stable junction characteristics under thermal cycling and radiation exposure.
Designed for high-stability references, it delivers low noise density (1 µV/√Hz) at 87 V and exhibits a +0.100 %/°C temperature coefficient - enabling predictable drift compensation in analog sensor front-ends and avionics power monitoring circuits.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4133US-1 | Same 87 V, ±2%, DO-213AA surface-mount package; lower RθJA (200 °C/W vs. 300 °C/W) | Used where board space is constrained and reflow assembly required | Select when automated SMT placement and higher thermal efficiency are prioritized over axial through-hole mounting |
| JANTXV1N4133C-1 | Identical electrical specs but qualified to JANTXV level (enhanced screening, 100% life test, tighter parametric limits) | Required for Class H (high reliability) military platforms with extended mission lifetimes | Select when full JANTXV conformance - including burn-in and lot acceptance testing - is mandated by program spec |
Compared with JANTX1N4133C-1, the 1N4133US-1 offers superior thermal performance in compact layouts, while JANTXV1N4133C-1 provides stricter screening for longer field life - both retain identical 87 V regulation and 1 µV/√Hz noise, making them functionally aligned alternatives rather than drop-in replacements.

FAQ
What is the Zener voltage and tolerance of JANTX1N4133C-1?
JANTX1N4133C-1 has a nominal Zener voltage of 87 V with a ±2% tolerance, measured at 250 mA test current and 25 °C ambient. The "C" suffix explicitly denotes the 2% tolerance grade, verified per MIL-PRF-19500/435 screening requirements. This tolerance enables tighter system-level calibration in high-voltage reference designs without post-production trimming.
Is JANTX1N4133C-1 suitable for space applications?
Yes, JANTX1N4133C-1 is inherently radiation-hardened per Microsemi MicroNote 050 and qualified to JANTX level under MIL-PRF-19500/435, supporting total ionizing dose (TID) resilience required for low-earth orbit missions. Its hermetic DO-35 glass package and metallurgical bond further ensure reliability in vacuum and thermal cycling environments typical of spacecraft subsystems.
What is the maximum reverse leakage current for JANTX1N4133C-1?
JANTX1N4133C-1 specifies a maximum reverse leakage current (IR) of 10 nA at 69.6 V (80% of VZ). This ultra-low leakage ensures minimal power loss and signal perturbation in high-impedance reference nodes, critical for battery-backed avionics monitors and precision sensor bridges where standby current must remain below 100 nA.
How does the temperature coefficient affect JANTX1N4133C-1 performance?
JANTX1N4133C-1 has a temperature coefficient of +0.100 %/°C, meaning its Zener voltage increases by approximately 87 mV per °C rise. This predictable positive drift allows designers to compensate system gain errors in wide-temperature-range applications - for example, pairing with negative-TC resistors in voltage dividers for net-zero drift over -65 to +175 °C.
What packaging options exist for JANTX1N4133C-1?
JANTX1N4133C-1 is supplied in the axial-leaded DO-35 (DO-204AH) glass package with tin-lead plating. Tape-and-reel (TR) packaging is available upon request with "TR" suffix added to the part number. Surface-mount variants like 1N4133US-1 (DO-213AA) exist but require separate ordering and are not interchangeable without layout revision.
