Product details
Overview
JANTXV1N4962CUS/TR from Microsemi is a military-grade, hermetically sealed surface-mount Zener diode rated for 5 W power dissipation, with nominal Zener voltage of 15 V at 75 mA test current, ±2% tolerance (C suffix), and operating junction temperature range of −65 °C to +175 °C. It serves as a precision voltage reference and regulation element in high-reliability power supply rails and overvoltage protection circuits for aerospace and defense electronics.
For engineers reviewing the JANTXV1N4962CUS/TR datasheet, JANTXV1N4962CUS/TR pinout, JANTXV1N4962CUS/TR application, or JANTXV1N4962CUS/TR equivalent, key selection criteria include its voidless-glass package, Category I metallurgical bond, 3.5 Ω dynamic impedance at IZT, 5 mA maximum reverse leakage at 11.4 V, and compliance with MIL-PRF-19500/356 Class JANTXV.
Technical Context
This device operates in reverse breakdown mode with tightly controlled Zener voltage regulation across wide current (10%–50% of IZM) and temperature ranges. Its voidless hermetic glass construction eliminates internal delamination risks and supports long-term stability under thermal cycling and radiation exposure.
The JANTXV1N4962CUS/TR features triple-layer passivation, nonsensitivity to ESD per MIL-STD-750 Method 1020, and inherent radiation hardness documented in MicroNote 050. Its thermal resistance is 7 °C/W (junction-to-end-cap), enabling reliable 5 W operation up to 140 °C end-cap temperature before linear derating to zero at 175 °C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4962US | Commercial-grade version; same 15 V ±5% (no C suffix), no MIL-PRF-19500 screening | Lacks JANTXV-level burn-in, temperature cycling, and radiation assurance | Select for non-mission-critical industrial systems where cost sensitivity outweighs lifetime reliability requirements |
| JANTX1N4962CUS/TR | Same electrical specs and package, but JANTX screening level (lower reliability assurance than JANTXV) | Excludes some high-temp life testing and radiation characterization steps defined in MIL-PRF-19500/356 Table I | Choose when program requirements mandate MIL-qualified parts but do not require full JANTXV radiation or extended life validation |
Compared with JANTXV1N4962CUS/TR, the 1N4962US offers identical regulation performance at lower cost but no military screening, while JANTX1N4962CUS/TR provides partial qualification-making the JANTXV grade essential for systems requiring verified radiation hardness and 20+ year field life.

FAQ
What is the Zener voltage tolerance of JANTXV1N4962CUS/TR?
The JANTXV1N4962CUS/TR has a nominal Zener voltage of 15 V with ±2% tolerance, indicated by the "C" suffix in the part number. This tighter tolerance is achieved through post-screening binning and is validated per MIL-PRF-19500/356 test requirements for JANTXV devices.
Does JANTXV1N4962CUS/TR require external heat sinking?
No, JANTXV1N4962CUS/TR does not require external heat sinking under standard operating conditions. Its 7 °C/W junction-to-end-cap thermal resistance and 5 W rating allow full power dissipation at end-cap temperatures up to 140 °C, with linear derating to zero at 175 °C.
Is JANTXV1N4962CUS/TR compatible with lead-free reflow processes?
JANTXV1N4962CUS/TR uses Sn/Pb finish on copper end caps and is not rated for lead-free reflow. Its maximum peak reflow temperature is limited to 235 °C per MIL-STD-202 Method 210, making it incompatible with standard SAC305 (245 °C peak) profiles.
What is the maximum surge current rating for JANTXV1N4962CUS/TR?
JANTXV1N4962CUS/TR is rated for 12 A nonrepetitive surge current at an 8.3 ms half-sine waveform, as specified in the Electrical Characteristics table. This rating enables protection against induced transients in MIL-STD-461-compliant platforms.
How is cathode polarity marked on JANTXV1N4962CUS/TR?
The cathode of JANTXV1N4962CUS/TR is marked by a visible band on the glass body, consistent with JEDEC-standard polarity identification for axial and surface-mount Zener diodes. No alphanumeric marking is applied per the datasheet.
