For engineers reviewing the JANTXV1N4624D-1 datasheet, JANTXV1N4624D-1 pinout, JANTXV1N4624D-1 application, or JANTXV1N4624D-1 equivalent, key selection factors include its 4.7 V nominal Zener voltage at 250 mA test current, 1550 Ω dynamic impedance, 5.0 µA max reverse leakage at 3.0 V, 75 mA maximum Zener current, and -0.050,+0.020 %/°C temperature coefficient.
Technical Context
This device operates as a precision shunt voltage regulator with a sharp breakdown knee (IZK = 250 mA), enabling stable reference generation across wide current and temperature ranges. Its metallurgical bond construction ensures low noise density (1 µV/√Hz typical) and inherent radiation hardness per Microsemi MicroNote 050.
The JANTXV1N4624D-1 exhibits a non-linear temperature coefficient of -0.050,+0.020 %/°C and is rated for junction temperatures from -65 °C to +175 °C, supporting operation in extreme environments without derating until lead temperature exceeds 50 °C.

FAQ
What is the Zener voltage tolerance of JANTXV1N4624D-1?
JANTXV1N4624D-1 has a nominal Zener voltage of 4.7 V with a ±1% tolerance, meaning the actual regulated voltage falls between 4.653 V and 4.747 V at 250 mA test current and 25 °C ambient. This tight tolerance is achieved via post-manufacturing screening and is specified per MIL-PRF-19500/435 JANTXV level requirements.
Is JANTXV1N4624D-1 suitable for high-radiation environments?
Yes, JANTXV1N4624D-1 is inherently radiation hard due to its metallurgically bonded construction, as documented in Microsemi MicroNote 050. It maintains parametric stability after exposure to total ionizing dose (TID) up to 100 krad(Si), making it suitable for satellite and nuclear instrumentation applications.
What is the maximum allowable Zener current for JANTXV1N4624D-1?
The maximum Zener current (IZM) for JANTXV1N4624D-1 is 75 mA at 25 °C lead temperature. Above 50 °C lead temperature, power must be linearly derated per Figure 2 in the datasheet, reaching zero dissipation at 175 °C junction temperature.
Does JANTXV1N4624D-1 require special ESD handling?
No, JANTXV1N4624D-1 is non-sensitive to ESD per MIL-STD-750 Method 1020. Its robust glass package and metallurgical bond eliminate the need for ESD-safe workstations or packaging during handling and assembly.
How does the temperature coefficient of JANTXV1N4624D-1 affect its regulation accuracy?
JANTXV1N4624D-1 has a temperature coefficient of -0.050,+0.020 %/°C, meaning its Zener voltage may decrease by up to 0.050% or increase by up to 0.020% per degree Celsius change. Over a -55 °C to +125 °C range, this results in ≤±9.5 mV total drift from nominal 4.7 V, critical for precision analog subsystems.
