For engineers reviewing the JAN1N4108D-1/TR datasheet, JAN1N4108D-1/TR pinout, JAN1N4108D-1/TR application, or JAN1N4108D-1/TR equivalent, key selection criteria include Zener voltage tolerance (±1%), dynamic impedance (200 Ω @ 250 mA), noise density (1 μV/√Hz), temperature coefficient (+0.085 %/°C), and JANS-qualified reliability grading.
Technical Context
This device operates as a precision shunt voltage regulator with metallurgically bonded construction ensuring stable breakdown characteristics across -65 °C to +175 °C junction temperature range. Its low noise density and tight 1% voltage tolerance support reference-grade applications where thermal drift and spectral purity are critical.
The JAN1N4108D-1/TR exhibits a positive temperature coefficient of +0.085 %/°C and maintains regulated output at test current IZT = 250 mA, with maximum Zener impedance ZZT = 200 Ω and reverse leakage IR ≤ 0.05 μA at VR = 11.2 V - enabling stable operation under varying load and thermal conditions.

FAQ
What is the Zener voltage and tolerance of JAN1N4108D-1/TR?
JAN1N4108D-1/TR has a nominal Zener voltage of 14.0 V with a ±1% tolerance, measured at 250 mA test current under thermal equilibrium at 25 °C. This tight tolerance is achieved via process-controlled metallurgical bonding and is validated per MIL-PRF-19500/435 screening requirements for JAN-level devices.
What does the "D" in JAN1N4108D-1/TR signify?
The "D" in JAN1N4108D-1/TR denotes 1% Zener voltage tolerance per the Microsemi part nomenclature guide. It is distinct from "C" (2%) and blank (5%), and applies exclusively to the specified 14.0 V device within the 1N4100–1N4135 series. The "TR" suffix indicates tape-and-reel packaging per EIA-296 standard.
Is JAN1N4108D-1/TR suitable for high-temperature operation?
Yes, JAN1N4108D-1/TR is rated for junction temperatures from -65 °C to +175 °C and is qualified per MIL-PRF-19500/435 for high-reliability operation. Its thermal resistance junction-to-lead is 250 °C/W at 3/8″ lead length, enabling stable regulation in engine bay or avionics bay environments without derating below 500 mW until case temperature exceeds 50 °C.
How does the noise performance of JAN1N4108D-1/TR compare to lower-voltage Zeners?
JAN1N4108D-1/TR exhibits 1 μV/√Hz noise density at 250 mA, consistent with Microsemi's specification that noise falls rapidly below 6.8 V - where it reaches 1 μV/√Hz - and remains flat across the 14 V rating. This makes it suitable for low-noise analog references, unlike higher-voltage Zeners (>24 V) which typically show increased noise.
Can JAN1N4108D-1/TR be used as a replacement for commercial-grade 1N4108-1?
JAN1N4108D-1/TR is not a direct drop-in replacement for commercial 1N4108-1 due to its 1% tolerance (vs. 5%), JAN-level screening, and RoHS-compliant plating only on commercial variants. While electrically compatible in regulation function, its enhanced reliability testing, traceability, and tighter spec require validation in systems originally designed for commercial-grade stress screening and qualification levels.
