Product details
Overview
1N4106-1/TR from Microsemi is a 500 mW, 12.0 V ±5% metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to JANTXV level per MIL-PRF-19500/435, with 200 Ω dynamic impedance at 250 mA, 9.2 mA maximum Zener current, and +0.080 %/°C temperature coefficient - used for precision voltage regulation in military power supplies and analog reference circuits.
For engineers reviewing the 1N4106-1/TR datasheet, 1N4106-1/TR pinout, 1N4106-1/TR application, or 1N4106-1/TR equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (250 °C/W junction-to-lead), noise density (≤1 µV/√Hz below 6.8 V), radiation hardness, and RoHS-compliant plating options.
Technical Context
The 1N4106-1/TR operates as a reverse-biased voltage reference with a nominal Zener voltage of 12.0 V at 250 mA test current, exhibiting 200 Ω dynamic impedance (ZZT) and 0.05 µA maximum reverse leakage at 9.2 V. Its metallurgical bond construction ensures stable regulation across -65 °C to +175 °C junction temperature range.
Designed for high-reliability applications, it meets MIL-PRF-19500/435 requirements at JANTXV level, features hermetically sealed glass packaging, and delivers low capacitance (<2 pF typical at 12 V) and ESD immunity per MIL-STD-750 Method 1020.

FAQ
What is the Zener voltage tolerance for the 1N4106-1/TR?
The 1N4106-1/TR has a nominal Zener voltage of 12.0 V with a standard tolerance of ±5%, as defined in the JEDEC-registered specification and confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This tolerance applies at 25 °C with the diode in thermal equilibrium and is maintained across the JANTXV qualification level.
Is the 1N4106-1/TR RoHS compliant?
Yes, the 1N4106-1/TR is RoHS compliant when ordered with the "e3" suffix (e.g., 1N4106-1e3/TR). Per the datasheet, RoHS-compliant matte-tin plating is available on commercial-grade versions only; JANTXV-qualified units may be non-RoHS unless explicitly specified with e3. The TR suffix denotes tape-and-reel packaging and does not affect RoHS status.
What is the maximum Zener current (IZM) for the 1N4106-1/TR?
The maximum Zener current (IZM) for the 1N4106-1/TR is 9.2 mA, as specified in the Electrical Characteristics table. This value corresponds to the current at which the device reaches its rated 500 mW power dissipation at 12.0 V, assuming ideal thermal conditions at TL = 25 °C before derating begins at 50 °C.
Does the 1N4106-1/TR have radiation hardness certification?
Yes, the 1N4106-1/TR is inherently radiation hard per Microsemi MicroNote 050, a documented characteristic of its metallurgically bonded glass construction and hermetic sealing. While not individually tested per MIL-STD-883, its design and material system provide proven TID tolerance - a key reason for its use in satellite and nuclear instrumentation applications.
What is the thermal resistance junction-to-lead (RθJL) for the 1N4106-1/TR?
The thermal resistance junction-to-lead (RθJL) for the 1N4106-1/TR is 250 °C/W, measured with 3/8 inch (10 mm) lead length from the body, as stated in the Maximum Ratings table on page 1 of T4-LDS-0245-2 Rev. 1. This value guides heatsinking decisions when mounting on chassis or thermally conductive leads.
