Product details
Overview
JAN1N4133-1 from Microsemi is a 500 mW, 87 V, ±5% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to JAN level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JAN1N4133-1 datasheet, JAN1N4133-1 pinout, JAN1N4133-1 application, or JAN1N4133-1 equivalent, key selection criteria include its 87 V nominal Zener voltage at 250 mA test current, 1000 Ω maximum dynamic impedance, 40 µA maximum reverse leakage at 69.6 V, radiation-hardened construction, and hermetic glass sealing for stable operation across -65°C to +175°C.
Technical Context
This device operates as a precision shunt voltage regulator with a specified Zener voltage of 87 V at IZT = 250 mA, exhibiting a temperature coefficient of +0.100 %/°C and low noise density of 1 µV/√Hz. Its metallurgical bond ensures mechanical robustness under thermal cycling and shock.
The JAN1N4133-1 is rated for 500 mW average power dissipation at TL = 25°C, derating linearly to zero at 175°C, with thermal resistance junction-to-lead of 250 °C/W at 10 mm lead length. It maintains ≤40 µA reverse current at VR = 69.6 V and exhibits 4.4 mA maximum Zener current (IZM) under rated power.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4133-1 | Higher screening level (JANTXV) with extended temperature testing and tighter parametric limits | Required for mission-critical flight hardware where failure modes must be statistically bounded | Select when full JANTXV qualification documentation and 100% lot testing are mandated by program requirements |
| 1N4133US-1 | Same electrical specs but in surface-mount DO-213AA package; no axial leads | Used where automated assembly and board space constraints preclude through-hole mounting | Select when PCB layout requires SMT placement and reflow compatibility without manual lead forming |
Compared with JAN1N4133-1, JANTXV1N4133-1 offers enhanced screening confidence for flight-critical systems, while 1N4133US-1 enables identical regulation performance in compact SMT layouts-neither is pin-compatible due to differing packages, requiring mechanical redesign.

FAQ
What is the Zener voltage tolerance for JAN1N4133-1?
JAN1N4133-1 has a nominal Zener voltage of 87 V with a ±5% tolerance, meaning its actual breakdown voltage falls between 82.65 V and 91.35 V when measured at 250 mA test current and 25°C ambient. This tolerance is inherent to the JEDEC-standardized JAN-level qualification and applies across the full operating temperature range.
Is JAN1N4133-1 RoHS compliant?
No, JAN1N4133-1 is not RoHS compliant. The "e3" RoHS designation applies only to commercial-grade versions (e.g., 1N4133-1e3); JAN-level parts retain traditional tin-lead plating to meet MIL-STD-750 solderability and reliability requirements, and do not carry RoHS exemptions or compliance markings.
What is the maximum Zener current (IZM) for JAN1N4133-1?
The maximum Zener current for JAN1N4133-1 is 4.4 mA at 500 mW power dissipation and 25°C lead temperature. This value is derived from PM(AV)/VZ = 0.5 W / 87 V ≈ 5.75 mA, adjusted downward per derating curves and thermal resistance to ensure safe junction operation under real-world lead-mount conditions.
Does JAN1N4133-1 have radiation hardness specifications?
Yes, JAN1N4133-1 is inherently radiation hard as described in Microsemi MicroNote 050. It exhibits tolerance to total ionizing dose (TID) without parameter degradation, making it suitable for use in space and nuclear environments where single-event effects and cumulative dose are concerns-no additional hardening is required.
What is the thermal resistance junction-to-lead (RθJL) for JAN1N4133-1?
JAN1N4133-1 has a thermal resistance junction-to-lead of 250 °C/W when mounted with 10 mm (3/8 inch) lead length from the body, per MIL-PRF-19500/435 test conditions. This value assumes standard FR4 PCB mounting with 4 mm² copper pads and is used to calculate junction temperature rise under actual operating current and ambient conditions.
