Product details
Overview
JAN1N4115-1/TR from Microsemi is a 500 mW, 22.0 V ±5% metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to JAN level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JAN1N4115-1/TR datasheet, JAN1N4115-1/TR pinout, JAN1N4115-1/TR application, or JAN1N4115-1/TR equivalent, key selection criteria include its 22.0 V nominal Zener voltage at 250 mA test current, 150 Ω dynamic impedance, 0.01 µA max reverse leakage at 17.6 V, +0.090 %/°C temperature coefficient, and hermetically sealed glass construction for stable regulation across -65 °C to +175 °C.
Technical Context
This device operates as a precision shunt voltage regulator with a defined breakdown knee at IZK and a specified Zener test current (IZT = 250 mA) where VZ = 22.0 V is guaranteed. Its metallurgical bond ensures low noise density (1 µV/√Hz typical at lower voltages) and minimal capacitance (≈3 pF at 22 V), critical for low-noise reference circuits.
The diode exhibits a positive temperature coefficient (+0.090 %/°C), enabling predictable voltage drift over temperature, and is rated for 0.5 W average power dissipation with linear derating from 25 °C ambient to zero at 175 °C on standard FR4 PCBs.

FAQ
What is the Zener voltage tolerance for JAN1N4115-1/TR?
The JAN1N4115-1/TR has a nominal Zener voltage of 22.0 V with a standard ±5% tolerance, consistent with JEDEC registration for the 1N4099–1N4135 series. This tolerance applies at 250 mA test current and 25 °C ambient temperature, and is verified per MIL-PRF-19500/435 screening requirements for JAN-level devices.
Is JAN1N4115-1/TR RoHS compliant?
No, JAN1N4115-1/TR is not RoHS compliant. The "e3" suffix denotes RoHS-compliant versions, which are only available for commercial-grade parts-not for JAN, JANTX, JANTXV, or JANS reliability levels. JAN1N4115-1/TR uses traditional tin-lead plating per MIL-STD-750 method 2026.
What is the maximum reverse leakage current for JAN1N4115-1/TR?
The maximum reverse leakage current for JAN1N4115-1/TR is 0.01 µA at VR = 17.6 V (80% of nominal Zener voltage), measured at 25 °C. This ultra-low leakage supports high-impedance bias networks and minimizes standby power loss in battery-operated systems.
Can JAN1N4115-1/TR be used in surface-mount designs?
No, JAN1N4115-1/TR is packaged in the axial-leaded DO-35 (DO-204AH) glass case and is intended for through-hole mounting. For surface-mount equivalents, consider the 1N4115US-1 in DO-213AA or 1PMT4115 in DO-216, both sharing identical electrical characteristics but different mechanical form factors.
What is the thermal resistance specification for JAN1N4115-1/TR?
JAN1N4115-1/TR has a junction-to-lead thermal resistance (RθJL) of 250 °C/W when mounted with 10 mm lead length from body, and junction-to-ambient (RθJA) of 300 °C/W on FR4 PCB with 4 mm² copper pads. These values define safe operating area limits under continuous DC power dissipation.
