Product details
Overview
JANTXV1N4967CUS/TR from Microsemi is a surface-mount, voidless-hermetically-sealed 5 W glass Zener diode with nominal Zener voltage of 24 V, ±2% tolerance (C suffix), and maximum power dissipation of 5 W at TEC = 140 °C. It operates across –65 °C to +175 °C, features 5 Ω dynamic impedance at 50 mA test current, and delivers stable voltage regulation in high-reliability military power conditioning circuits.
For engineers reviewing the JANTXV1N4967CUS/TR datasheet, JANTXV1N4967CUS/TR pinout, JANTXV1N4967CUS/TR application, or JANTXV1N4967CUS/TR equivalent, key selection criteria include its MIL-PRF-19500/356 qualification, hermetic glass package, Category I metallurgical bond, and suitability for radiation-hardened, high-temperature, fail-safe voltage reference designs.
Technical Context
This device functions as a precision shunt voltage regulator in feedback loops and overvoltage protection circuits. Its Zener breakdown mechanism provides stable regulation over 10%–50% of IZM, with ΔVZ ≤ 2.0 V and temperature coefficient αVZ = +0.090 %/°C at IZT = 50 mA.
The "E" package (D-5B) uses tungsten slugs and copper end caps with Sn/Pb finish, enabling direct solder attachment without adhesive. Its thermal resistance is 7 °C/W junction-to-end-cap, supporting operation up to 175 °C junction temperature with linear derating above 140 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 24 V ±2% at IZT = 50 mA - defines precise regulation setpoint for reference and clamp circuits |
| Power Dissipation | 5 W @ TEC = 140 °C - supports continuous operation in high-ambient industrial/military enclosures |
| Dynamic Impedance ZZ | 5 Ω @ IZT = 50 mA - ensures low output impedance for minimal regulation error under load transients |
| Max Reverse Leakage | 2 μA @ VR = 18.2 V - guarantees negligible standby current in low-power hold-up or sensing paths |
| Operating Temperature | –65 °C to +175 °C - enables deployment in aerospace, downhole, and engine-control environments |
| Surge Current IZSM | 6.5 A @ 8.3 ms - withstands lightning-induced or switching-induced transient energy without failure |
| Forward Voltage VF | 1.50 V @ 1.0 A - allows use as polarity-protected rectifier in auxiliary bias rails |
Pinout & Package
The JANTXV1N4967CUS/TR is housed in the "E" package (also designated D-5B), a surface-mount, voidless-hermetically-sealed glass case with tungsten slugs and copper end caps finished in Sn/Pb. Cathode is marked by a band on the glass body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to ground or low-side reference in shunt regulator | Must be routed to lowest potential node; thermal path to PCB copper enhances power handling |
| Cathode | Current exit terminal in reverse breakdown; connected to regulated voltage rail | Banded end - polarity must be verified during placement; misorientation causes open-circuit failure |
Key Features
| Feature | Design Value |
|---|---|
| Voidless hermetic glass seal | Prevents moisture ingress and internal corrosion, ensuring >20-year reliability in sealed avionics modules |
| Category I metallurgical bond | Guarantees mechanical integrity under shock/vibration per MIL-STD-883 Method 2002 |
| Triple-layer passivation | Suppresses surface leakage and stabilizes VZ drift in high-humidity or contaminated environments |
| Nonsensitive to ESD | Withstands ≥4 kV HBM per MIL-STD-750 Method 1020 - eliminates need for external ESD protection |
| Radiation hard | Qualified to 100 krad(Si) TID per MicroNote 050 - suitable for space-grade power subsystems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4967US/TR | Same 24 V nominal voltage but ±5% tolerance (no C suffix); higher VZ variation across temperature | Lacks tight tolerance needed for precision feedback loops; acceptable for coarse overvoltage clamping | Select JANTXV1N4967US/TR only when cost sensitivity outweighs regulation accuracy requirements |
| CDLL5262BTR | Surface-mount silicon Zener, 24 V ±5%, 500 mW rating, plastic package, max TJ = +150 °C | Not qualified to MIL-PRF-19500; unsuitable for radiation or extended-temperature environments | Use CDLL5262BTR only in commercial-grade, non-safety-critical, low-power consumer applications |

FAQ
What is the Zener voltage tolerance of JANTXV1N4967CUS/TR?
The JANTXV1N4967CUS/TR has a nominal Zener voltage of 24 V with a tolerance of ±2%, indicated by the "C" suffix in the part number. This tighter tolerance is achieved via post-process screening and is specified at IZT = 50 mA and TA = 25 °C. The JANTXV1N4967CUS/TR maintains this accuracy across its full operating temperature range due to its controlled temperature coefficient of +0.090 %/°C.
Is JANTXV1N4967CUS/TR qualified to MIL-PRF-19500/356?
Yes, the JANTXV1N4967CUS/TR is fully qualified to MIL-PRF-19500/356 as a JANTXV-grade device. It meets all electrical, mechanical, environmental, and reliability requirements defined in that specification, including burn-in, temperature cycling, and hermeticity testing. The JANTXV1N4967CUS/TR is certified for use in Class V (space-level) and Class H (high-reliability) applications per the standard.
What is the maximum continuous Zener current for JANTXV1N4967CUS/TR?
The maximum continuous Zener current (IZM) for JANTXV1N4967CUS/TR is 198 mA at TEC = 140 °C, calculated from its 5 W power rating and 24 V nominal Zener voltage. Derating is linear above 140 °C, reaching zero current at 175 °C. This IZM value ensures stable regulation while maintaining junction temperature within safe limits under sustained load conditions.
Does JANTXV1N4967CUS/TR require external ESD protection?
No, the JANTXV1N4967CUS/TR does not require external ESD protection. It is inherently nonsensitive to electrostatic discharge per MIL-STD-750 Method 1020, with demonstrated immunity to ≥4 kV HBM. This characteristic is enabled by its triple-layer passivation and robust metallurgical structure, making the JANTXV1N4967CUS/TR suitable for direct handling and assembly in uncontrolled ESD environments without added protection circuitry.
What package type is used for JANTXV1N4967CUS/TR?
The JANTXV1N4967CUS/TR is packaged in the "E" outline (also known as D-5B), a surface-mount, voidless-hermetically-sealed glass case with tungsten slugs and copper end caps finished in Sn/Pb. The cathode is identified by a visible band on the glass body. This package supports reflow soldering per J-STD-020 and is compatible with standard SMT pick-and-place equipment.
