Overview
JANS1N4616C-1/TR from Microsemi is a 2.2 V, 500 mW, 2% tolerance metallurgically bonded glass Zener diode in DO-35 package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense applications. It delivers stable voltage regulation at 250 mA test current with 1300 Ω dynamic impedance and -0.075 %/°C temperature coefficient.
For engineers reviewing the JANS1N4616C-1/TR datasheet, JANS1N4616C-1/TR pinout, JANS1N4616C-1/TR application, or JANS1N4616C-1/TR equivalent, key selection criteria include Zener voltage tolerance (2%), radiation hardness, hermetic glass packaging, low noise density (1 µV/√Hz), and military-grade thermal derating behavior up to +175 °C junction temperature.
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, critical for space-qualified systems.
It exhibits a negative temperature coefficient (-0.075 %/°C) across its operating range, enabling predictable drift compensation in reference circuits. The DO-35 package supports axial-leaded through-hole mounting with tin-lead or RoHS-compliant matte-tin plating, solderable per MIL-STD-750 method 2026.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4616C-1 | Same electrical specs, but qualified only to JANTXV level (not JANS); lacks full Class S radiation testing and extended life screening. | Approved for high-reliability ground-based radar and missile guidance, but not certified for spacecraft payload use. | Select when full JANS qualification is not mandated and cost sensitivity is higher. |
| 1N4616C-1/TR | Commercial-grade version; same DO-35 package and 2.2 V/2% spec, but no MIL-PRF-19500 qualification or radiation hardness data. | Suitable for industrial test equipment and medical devices where environmental stress is moderate and traceability is not required. | Choose for prototyping or non-safety-critical production where JANS-level assurance is unnecessary. |
Compared with JANTXV1N4616C-1 and 1N4616C-1/TR, the JANS1N4616C-1/TR provides verified radiation hardness, full lot traceability, and extended temperature survivability-making it the sole option for Class S spaceflight applications requiring guaranteed parametric stability after total ionizing dose exposure.

Yes, JANS1N4616C-1/TR is qualified to JANS level per MIL-PRF-19500/435, including radiation hardness assurance per Microsemi MicroNote 050. It is approved for Class S space applications where long-term parametric stability under total ionizing dose (TID) and displacement damage is required. Full lot traceability and extended life testing are part of its qualification.
What is the maximum power dissipation and thermal derating behavior of JANS1N4616C-1/TR?
JANS1N4616C-1/TR is rated for 500 mW average power dissipation at 25 °C lead temperature, with linear derating to zero at +175 °C. Thermal resistance is 250 °C/W junction-to-lead (with 10 mm lead length) and 300 °C/W junction-to-ambient on FR4 board. This derating curve is validated per MIL-PRF-19500/435 and documented in Figure 2 of the T4-LDS-0245-2 datasheet.
Does JANS1N4616C-1/TR have low noise performance suitable for precision references?
Yes, JANS1N4616C-1/TR delivers 1 µV/√Hz noise density at 250 mA test current, among the lowest in the 1N46xx family. This ultra-low noise enables direct use in high-resolution data acquisition systems and precision op-amp bias networks without additional filtering. Noise is measured per Figure 1 using a 1–3 kHz bandpass filter at 25 °C.
What package type and marking does JANS1N4616C-1/TR use?
JANS1N4616C-1/TR uses the hermetically sealed axial-leaded DO-35 (DO-204AH) glass package with cathode indicated by a single black band. It is marked with the full part number "JANS1N4616C-1" and supplied in tape-and-reel format (TR suffix). Lead finish is tin-lead or RoHS-compliant matte-tin, solderable per MIL-STD-750 method 2026.
