Product details
Overview
JAN1N4615D-1/TR from Microsemi is a 2.0 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JAN1N4615D-1/TR datasheet, JAN1N4615D-1/TR pinout, JAN1N4615D-1/TR application, or JAN1N4615D-1/TR equivalent, key selection criteria include Zener voltage accuracy (±1%), low noise density (1 µV/√Hz), JANS-level radiation hardness, and hermetic DO-35 packaging for extreme-environment stability.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 2.0 V at 250 mA test current, exhibiting a temperature coefficient of –0.075 %/°C and dynamic impedance of 1250 Ω at IZT. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and mechanical stress.
Designed for operation in reverse-biased mode with cathode band positive, it delivers regulated output across wide current ranges (IZK to IZM = 120 mA) while maintaining low leakage (IR ≤ 2.5 µA at VR = 1.0 V) and minimal capacitance per Figure 3 - critical for low-noise analog references and precision biasing.
Key Specifications

| Dynamic Impedance ZZT | 1250 Ω at 250 mA - ensures minimal output voltage variation under load transients in feedback loops. |
| Noise Density ND | 1 µV/√Hz - provides ultra-low noise performance essential for high-resolution ADC references and sensor excitation. |
| Temp Coefficient αVZ | –0.075 %/°C - guarantees predictable, monotonic drift over –65 to +175 °C operating range. |
| Max Reverse Current IR | 2.5 µA at VR = 1.0 V - ensures negligible quiescent power loss in standby or low-current bias networks. |
| Junction Temp Range | –65 to +175 °C - validated for extended operation in military-grade avionics and space-qualified systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4615US-1/TR | Same electrical specs but in surface-mount DO-213AA package; no axial leads. | Required for automated SMT assembly; unsuitable for through-hole prototyping or high-vibration mechanical retention. | Select when board space is constrained and reflow compatibility is mandatory. |
| JANTXV1N4615D-1 | Identical Zener parameters and 1% tolerance, but qualified only to JANTXV (not JANS); lower radiation hardness assurance. | Acceptable for airborne non-space systems where TID <50 krad(Si) is sufficient; not certified for spacecraft use. | Choose for cost-sensitive defense electronics where full JANS testing is unnecessary. |
Compared with JAN1N4615D-1/TR, 1N4615US-1/TR offers SMT compatibility at the expense of mechanical robustness, while JANTXV1N4615D-1 reduces qualification cost and radiation assurance - both require redesign for mounting or mission assurance scope.

FAQ
What is the Zener voltage tolerance of JAN1N4615D-1/TR?
JAN1N4615D-1/TR has a nominal Zener voltage of 2.0 V with ±1% tolerance, as indicated by the "D" suffix in its part number per Microsemi's nomenclature. This tight tolerance is verified at 250 mA test current and enables direct use in precision reference circuits without post-production trimming or calibration.
Is JAN1N4615D-1/TR suitable for space applications?
Yes, JAN1N4615D-1/TR is qualified to JANS level per MIL-PRF-19500/435 and exhibits inherent radiation hardness per Microsemi MicroNote 050. Its hermetic DO-35 package and metallurgical bond construction make it appropriate for low-earth orbit and deep-space missions where total ionizing dose and displacement damage must be mitigated.
What is the maximum Zener current IZM for JAN1N4615D-1/TR?
The maximum Zener current IZM for JAN1N4615D-1/TR is 110.0 mA, derived from its 500 mW power rating and 2.0 V Zener voltage (P = V × I). This value is valid at 25 °C and must be linearly derated above 50 °C lead temperature per Figure 2 in the datasheet.
Does JAN1N4615D-1/TR have RoHS compliance?
No, JAN1N4615D-1/TR is not RoHS compliant. The "e3" suffix denotes RoHS compliance, which is only available on commercial-grade versions. JAN-level parts like JAN1N4615D-1/TR use traditional tin-lead plating per MIL-STD-750 and are exempt from RoHS requirements for high-reliability applications.
How is polarity marked on JAN1N4615D-1/TR?
JAN1N4615D-1/TR uses a single black cathode band on the glass body to indicate polarity. The banded end is the cathode and must be held positive relative to the anode for proper Zener regulation. This marking conforms to JEDEC standards and is visible under standard visual inspection.
