Product details
Overview
JAN1N4113-1/TR from Microsemi is a 500 mW, 19.0 V ±5% metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to JAN level per MIL-PRF-19500/435. It delivers stable voltage regulation at 250 mA test current with 150 Ω dynamic impedance, <0.05 µA reverse leakage at 15.2 V, and +0.090 %/°C temperature coefficient - used in precision reference and power supply feedback circuits for aerospace avionics.
For engineers reviewing the JAN1N4113-1/TR datasheet, JAN1N4113-1/TR pinout, JAN1N4113-1/TR application, or JAN1N4113-1/TR equivalent, key selection criteria include its MIL-qualified reliability grade, low noise density (<1 µV/√Hz), hermetic DO-35 packaging, thermal resistance of 250 °C/W (junction-to-lead), and compatibility with high-reliability analog reference designs requiring stable 19 V regulation across -65 °C to +175 °C.
Technical Context
This Zener diode operates in reverse breakdown mode with cathode band indicating polarity, requiring banded end to be positive relative to anode for regulation. Its metallurgical bond construction ensures low noise and radiation hardness per MicroNote 050, while the DO-35 glass envelope provides hermetic sealing and ESD immunity per MIL-STD-750 method 1020.
The device exhibits a linear power derating curve: full 500 mW rating applies only up to 50 °C lead temperature, decreasing linearly to zero at 175 °C. At ambient conditions on FR4 board, derating begins at 25 °C with 300 °C/W junction-to-ambient thermal resistance, supporting operation in conduction-cooled military chassis environments.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4113US-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads | Requires SMT reflow process; unsuitable for through-hole prototyping or high-vibration mechanical retention | Select when board space is constrained and automated assembly is available |

FAQ
What is the Zener voltage tolerance for JAN1N4113-1/TR?
The JAN1N4113-1/TR has a nominal Zener voltage of 19.0 V with a standard tolerance of ±5%, as defined in the JEDEC-registered electrical characteristics table. This tolerance applies at 25 °C with the diode in thermal equilibrium and is verified per MIL-PRF-19500/435 screening requirements for JAN-level devices. The JAN1N4113-1/TR maintains this tolerance across its qualified operating temperature range.
Is JAN1N4113-1/TR RoHS compliant?
No, JAN1N4113-1/TR is not RoHS compliant. Per the nomenclature guide in the datasheet, the "e3" suffix denotes RoHS compliance, which is available only on commercial-grade versions. The JAN prefix indicates military-grade qualification, and this variant uses traditional tin-lead plating per MIL-STD-750 method 2026, not RoHS-compliant matte-tin.
What is the maximum reverse leakage current for JAN1N4113-1/TR?
The maximum reverse leakage current (IR) for JAN1N4113-1/TR is 0.05 µA at 15.2 V (80% of nominal VZ). This value is specified in the Electrical Characteristics table on page 3 of the datasheet and reflects worst-case leakage under rated conditions. The JAN1N4113-1/TR achieves this ultra-low leakage due to its metallurgically bonded construction and hermetic DO-35 packaging.
Can JAN1N4113-1/TR be used in surface-mount designs?
No, JAN1N4113-1/TR is packaged in the axial-leaded DO-35 (DO-204AH) through-hole format and is not suitable for direct surface-mount assembly. For SMT implementation, Microsemi offers the functionally equivalent 1N4113US-1 in DO-213AA package. The JAN1N4113-1/TR requires PCB mounting with axial lead holes and manual or wave soldering.
What is the thermal resistance junction-to-lead for JAN1N4113-1/TR?
The thermal resistance junction-to-lead (RθJL) for JAN1N4113-1/TR is 250 °C/W, measured with 3/8 inch (10 mm) lead length from the body. This value is critical for calculating junction temperature rise under load and is specified in the Maximum Ratings table. The JAN1N4113-1/TR relies on lead conduction for heat dissipation, making proper lead length and copper pad layout essential for maintaining 500 mW power capability.
