Product details
Overview
JANS1N4615C-1/TR from Microsemi is a 2.0 V, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANS level per MIL-PRF-19500/435, with ±2% Zener voltage tolerance, 1250 Ω dynamic impedance at 250 mA test current, and 1.0 µA maximum reverse leakage at 1.0 V. It delivers stable voltage regulation in high-reliability aerospace and defense power supply monitoring circuits.
For engineers reviewing the JANS1N4615C-1/TR datasheet, JANS1N4615C-1/TR pinout, JANS1N4615C-1/TR application, or JANS1N4615C-1/TR equivalent, key selection criteria include Zener voltage accuracy (±2%), low noise density (1 µV/√Hz), radiation hardness, hermetic DO-35 packaging, and MIL-qualified reliability levels for mission-critical analog reference design.
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 construction ensures mechanical stability under thermal cycling and shock.
The JANS1N4615C-1/TR exhibits a negative temperature coefficient of −0.075 %/°C and maintains ≤1250 Ω dynamic impedance (ZZT) at IZT = 250 mA, enabling predictable regulation across wide current ranges while minimizing output drift over temperature.

FAQ
What is the Zener voltage tolerance and test condition for JANS1N4615C-1/TR?
JANS1N4615C-1/TR has a nominal Zener voltage of 2.0 V with ±2% tolerance, measured at IZT = 250 mA and TJ = 25 °C under thermal equilibrium in still air. The "C" suffix explicitly denotes the 2% tolerance grade per Microsemi's nomenclature standard.
Is JANS1N4615C-1/TR radiation-hardened, and what documentation supports this claim?
Yes, JANS1N4615C-1/TR is inherently radiation-hardened as described in Microsemi MicroNote 050. Its metallurgically bonded structure and hermetic DO-35 package provide proven tolerance to total ionizing dose (TID), making it suitable for low-Earth orbit satellite applications without additional shielding.
What does the "JANS" prefix signify in JANS1N4615C-1/TR?
The "JANS" prefix indicates qualification to the highest reliability level defined in MIL-PRF-19500/435 - Class S (Space) - including full lot traceability, extended environmental screening, and compliance with MIL-STD-883 test methods for space-grade components.
Can JANS1N4615C-1/TR be used in surface-mount designs?
No - JANS1N4615C-1/TR uses the axial-leaded DO-35 (DO-204AH) through-hole package. Surface-mount alternatives include the JANS1N4615C-1UR in DO-213AA or 1PMT4615 in DO-216, which share identical electrical specs but differ in mounting and qualification scope.
What is the maximum Zener current IZM and how is it derived for JANS1N4615C-1/TR?
JANS1N4615C-1/TR has a maximum Zener current IZM of 110.0 mA, calculated from its 500 mW power rating and 2.0 V nominal Zener voltage (IZM = PM(AV)/VZ). This value assumes operation at 25 °C; derating applies linearly above 50 °C ambient per Figure 2 in the datasheet.
