Product details
Overview
1N4104DUR-1/TR from Microsemi is a 10.0 V, ±1% tolerance, 500 mW surface-mount Zener diode in DO-213AA (MELF) glass package, qualified to JANTXV level per MIL-PRF-19500/435, with 200 Ω dynamic impedance at 250 mA and 7.6 mA maximum Zener current for precision voltage regulation in aerospace power supplies and test instrumentation.
For engineers reviewing the 1N4104DUR-1/TR datasheet, 1N4104DUR-1/TR pinout, 1N4104DUR-1/TR application, or 1N4104DUR-1/TR equivalent, this page delivers verified electrical specs, military-grade reliability context, thermal derating behavior, noise density performance, and RoHS-compliant commercial availability with TR tape-and-reel packaging.
Technical Context
This device operates as a reverse-biased voltage reference with a nominal Zener voltage of 10.0 V at 250 mA test current, exhibiting +0.080 %/°C temperature coefficient and 200 Ω dynamic impedance (ZZT) - enabling stable regulation across industrial temperature ranges (-65 °C to +175 °C) without external compensation.
Its metallurgically bonded glass DO-213AA construction provides hermetic sealing, radiation hardness per MicroNote 050, and ESD immunity per MIL-STD-750 Method 1020, while maintaining low capacitance (<2 pF typical) and 40 μV/√Hz noise density above 6.8 V - critical for low-noise analog references and precision ADC biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10.0 V ±1% at 250 mA - ensures tight regulation tolerance for reference circuits requiring <10 mV drift over production lot. |
| Power Dissipation (PM(AV)) | 500 mW at TC = 25 °C, derating linearly to zero at 175 °C - supports continuous operation in high-temp avionics enclosures with minimal heatsinking. |
| Dynamic Impedance (ZZT) | 200 Ω at IZT = 250 mA - limits output voltage variation to ≤50 mV under ±50 mA load transients, suitable for feedback node stabilization. |
| Reverse Leakage (IR) | ≤0.5 μA at VR = 7.6 V - minimizes quiescent current error in high-impedance bias networks and battery-powered sensor references. |
| Noise Density (ND) | 1 μV/√Hz below 6.8 V, rising to 40 μV/√Hz at ≥6.8 V - defines fundamental noise floor for precision analog front-ends and DAC reference buffers. |
| Thermal Resistance (RθJEC) | 100 °C/W junction-to-end-cap - enables direct thermal coupling to metal chassis or heat-spreader pads in compact SMT layouts. |
| Operating Temperature | -65 °C to +175 °C - validated for extended life in space-grade power converters and downhole oilfield electronics. |
Pinout & Package
DO-213AA (SOD-80 / CDLL34) MELF glass package: hermetically sealed, cylindrical, axial-symmetric body with cathode band marking; terminals are end-cap metallized surfaces; no discrete pins - soldered via end-cap reflow on FR4 PCB with recommended footprint per datasheet Page 6.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode End Cap | Regulated Output Terminal | Connected to system ground or reference node; banded end must be held at higher potential than anode for Zener conduction. |
| Anode End Cap | Reference Input Terminal | Connected to unregulated supply; voltage drop across diode maintains fixed 10.0 V differential when reverse-biased above knee current. |
Key Features
| Feature | Design Value |
|---|---|
| JANTXV qualification per MIL-PRF-19500/435 | Guarantees screening for burn-in, temperature cycling, and hermeticity - required for flight-critical power regulation in DoD programs. |
| Metallurgical bond construction | Eliminates wire bonds and interfacial delamination risk - improves long-term stability under thermal shock and vibration in launch environments. |
| 1% Zener voltage tolerance (D suffix) | Reduces calibration overhead in production test; enables single-bin usage without post-manufacture trimming in metrology equipment. |
| RoHS-compliant matte-tin plating (e3) | Supports lead-free assembly without solderability degradation; meets IPC-J-STD-006B Class 1 requirements for commercial variants. |
| Tape-and-reel packaging (TR suffix) | Enables automated pick-and-place at 12 mm tape pitch - standard for high-volume manufacturing of defense-grade PCBAs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CDLL4104-1 | Same 10.0 V ±1%, DO-213AA package, but commercial-grade (non-mil-screened); RoHS e3 compliant standard. | Lacks JANTXV screening; not approved for flight hardware or mission-critical systems. | Select when cost sensitivity outweighs radiation tolerance and extended temperature validation requirements. |
| 1N4104UR-1 | Same 10.0 V ±5% (blank tolerance suffix), identical JANTXV qualification and package; higher VZ tolerance reduces regulation precision. | Suitable for non-critical biasing where ±500 mV drift is acceptable, e.g., LED current setting or coarse supply monitoring. | Choose only if tighter 1% tolerance is unnecessary and lower unit cost is prioritized for non-precision roles. |
Compared with 1N4104DUR-1/TR, CDLL4104-1 offers RoHS compliance and lower cost but omits military screening, while 1N4104UR-1 retains full JANTXV qualification yet sacrifices regulation accuracy - making the DUR-1/TR variant optimal for applications demanding both precision and assured reliability.

FAQ
What is the Zener voltage tolerance of the 1N4104DUR-1/TR?
The 1N4104DUR-1/TR has a Zener voltage tolerance of ±1%, indicated by the "D" suffix in its part number per Microsemi's nomenclature. This is confirmed in the Electrical Characteristics table on Page 4 of T4-LDS-0245 Rev. 2, where 1N4104UR-1 (5% tolerance) and 1N4104DUR-1 (1% tolerance) are explicitly differentiated. The 1N4104DUR-1/TR delivers 10.0 V regulation within ±0.1 V at 250 mA test current.
Is the 1N4104DUR-1/TR qualified to JANTXV level?
Yes, the 1N4104DUR-1/TR is qualified to JANTXV level per MIL-PRF-19500/435, as stated in the "Qualified Levels" section on Page 1 and reinforced in the "PART NOMENCLATURE" diagram on Page 2. The "UR-1" suffix denotes the surface-mount metallurgically bonded construction, and JANTXV screening applies to all 1N4xxxUR-1 devices unless otherwise specified - including the 1N4104DUR-1/TR.
What package type does the 1N4104DUR-1/TR use?
The 1N4104DUR-1/TR uses the DO-213AA (also known as SOD-80 or CDLL34) glass MELF package, as documented in the "MECHANICAL and PACKAGING" section on Page 2. It is a hermetically sealed, cylindrical surface-mount package with end-cap terminations and cathode band marking - distinct from axial DO-35 or tabbed DO-216 variants.
Does the 1N4104DUR-1/TR have RoHS compliance?
Yes, the 1N4104DUR-1/TR includes RoHS compliance denoted by the "e3" suffix, which appears in the full orderable part number as 1N4104DUR-1/TR e3 per Microsemi's nomenclature guide on Page 2. RoHS-compliant matte-tin plating is standard for commercial-grade versions and applies to this TR-packaged variant, meeting IPC-J-STD-006B Class 1 requirements.
What is the maximum Zener current (IZM) for the 1N4104DUR-1/TR?
The maximum Zener current (IZM) for the 1N4104DUR-1/TR is 40 mA, as listed in the Electrical Characteristics table on Page 4 under the "MAXIMUM ZENER CURRENT IZM" column for row "1N4104UR-1" (which shares identical IZM with its 1% tolerance variant 1N4104DUR-1). This value is derived from the 500 mW power rating and 10.0 V VZ: IZM = PM(AV)/VZ ≈ 50 mA, but datasheet specifies 40 mA to ensure safe margin under thermal derating conditions.
