Product details
Overview
JAN1N4626D-1 from Microsemi is a 5.6 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense systems. It delivers 5.6 V regulation at 250 mA test current with 1400 Ω dynamic impedance, 4.0 µA max reverse leakage at 4.2 V, and ±0.020%/°C temperature coefficient.
For engineers reviewing the JAN1N4626D-1 datasheet, JAN1N4626D-1 pinout, JAN1N4626D-1 application, or JAN1N4626D-1 equivalent, key selection criteria include its 1% Zener voltage tolerance, JANS-level qualification, 5.6 V nominal output, low noise density (≤4 µV/√Hz), and DO-35 axial-leaded hermetic packaging for radiation-hardened environments.
Technical Context
This device operates as a precision shunt voltage regulator in reverse-biased breakdown mode, with cathode band indicating polarity. Its metallurgical bond ensures stable junction characteristics under thermal cycling and radiation exposure, supporting operation from –65 °C to +175 °C.
The JAN1N4626D-1 exhibits a tightly controlled temperature coefficient of –0.020%/°C to +0.040%/°C, enabling stable regulation across wide temperature ranges without external compensation. Its 1400 Ω dynamic impedance at 250 mA IZT and 4.0 µA reverse current at VR = 4.2 V define load regulation and leakage behavior in precision reference circuits.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4626US-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads | Used where PCB real estate is constrained and reflow assembly required | Select when transitioning from through-hole to SMT without changing circuit topology |
| JANTXV1N4626D | Identical Zener parameters and 1% tolerance; differs only in qualification level (JANTXV vs JANS) | Approved for high-reliability programs requiring JANTXV but not full JANS radiation testing | Choose for cost-sensitive defense programs where full JANS testing is not mandated |
Compared with 1N4626US-1 and JANTXV1N4626D, the JAN1N4626D-1 uniquely combines JANS-level radiation hardness, axial DO-35 mounting flexibility, and metrology-grade 1% tolerance-making it irreplaceable in space-qualified reference designs where hermeticity and radiation survivability are non-negotiable.

FAQ
What is the Zener voltage tolerance of JAN1N4626D-1?
JAN1N4626D-1 has a ±1% Zener voltage tolerance at 250 mA test current, corresponding to a guaranteed 5.544 V to 5.656 V range at 25 °C. This tight tolerance is achieved via post-process screening and is maintained across the full –65 °C to +175 °C operating temperature range per MIL-PRF-19500/435 requirements.
Is JAN1N4626D-1 suitable for space applications?
Yes, JAN1N4626D-1 is qualified to JANS level per MIL-PRF-19500/435, including radiation hardness assurance per Microsemi MicroNote 050. Its metallurgically bonded junction and hermetic DO-35 package make it suitable for low-earth orbit and deep-space missions where total ionizing dose and single-event effects must be mitigated.
What is the maximum reverse leakage current for JAN1N4626D-1?
The maximum reverse leakage current for JAN1N4626D-1 is 4.0 µA at 4.2 V reverse voltage and 25 °C. This value is verified per MIL-STD-750 Test Method 3012 and remains below 10 µA across the full –65 °C to +125 °C range, ensuring minimal loading in high-impedance reference circuits.
Does JAN1N4626D-1 require derating above 25 °C?
Yes, JAN1N4626D-1 must be linearly derated from 500 mW starting at 25 °C ambient, reaching zero dissipation at 175 °C. Derating follows a slope of –3.33 mW/°C; at 75 °C ambient, maximum allowable power drops to 333 mW. This reflects its 300 °C/W junction-to-ambient thermal resistance on standard FR4 board.
Can JAN1N4626D-1 be used in RoHS-compliant designs?
No, JAN1N4626D-1 uses tin-lead plating per MIL-STD-750 and is not RoHS compliant. RoHS versions (e.g., 1N4626D-1e3) exist only in commercial-grade variants-not JAN, JANTX, JANTXV, or JANS levels. For high-reliability RoHS programs, alternative qualified parts must be selected.
