Product details
Overview
JANTXV1N4130D-1/TR from Microsemi is a 500 mW, 68 V, 1% tolerance metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4130D-1/TR datasheet, JANTXV1N4130D-1/TR pinout, JANTXV1N4130D-1/TR application, or JANTXV1N4130D-1/TR equivalent, key selection criteria include Zener voltage accuracy (±1%), low noise density (1 µV/√Hz), MIL-spec qualification level, thermal resistance (250 °C/W junction-to-lead), and hermetic DO-35 packaging for harsh-environment stability.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 68 V at 250 mA test current, exhibiting a positive temperature coefficient of +0.100 %/°C and dynamic impedance of 700 Ω at IZT. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
Designed for operation in the reverse-biased breakdown region, it delivers regulated output with ≤0.01 µA reverse leakage at 51.7 V and supports continuous DC regulation up to 40 mA maximum Zener current, with linear derating from 500 mW at 25 °C to zero at 175 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 68 V ±1% at 250 mA - enables precise reference generation for 65–71 V system rails |
| Power Dissipation | 500 mW at 25 °C - supports stable regulation in compact axial-leaded layouts without forced cooling |
| Dynamic Impedance ZZT | 700 Ω at 250 mA - limits output voltage variation under load transients within ±47.6 mV per 10 mA change |
| Noise Density | 1 µV/√Hz - critical for low-noise analog references and precision instrumentation front-ends |
| Reverse Leakage IR | ≤0.01 µA at 51.7 V - ensures minimal quiescent current draw in battery-backed or ultra-low-power circuits |
| Temp Coefficient αVZ | +0.100 %/°C - predictable drift behavior for temperature-compensated reference designs |
| Junction Temp Range | −65 to +175 °C - validated for extended operation in avionics, downhole, and space-grade thermal environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANS1N4130D-1 | JANS-level qualification (higher screening than JANTXV); identical electrical specs and DO-35 package | Required for space-flight hardware where radiation hardness and burn-in testing are mandatory | Select JANS1N4130D-1 only if program mandates JANS-level conformance per MIL-PRF-19500/435 Appendix A |
| 1N4130DUR-1TR | Surface-mount DO-213AA package; same 68 V/1%/500 mW specs but no MIL qualification | Suitable for commercial or industrial PCBs where automated assembly and board space constrain axial-leaded components | Choose 1N4130DUR-1TR when RoHS-compliant SMT placement is prioritized over military environmental ruggedness |
Compared with JANS1N4130D-1, the JANTXV1N4130D-1/TR offers lower cost and faster lead time while retaining full JANTXV reliability; versus 1N4130DUR-1TR, it trades SMT compatibility for guaranteed performance in extreme thermal and radiation environments.

FAQ
What is the Zener voltage tolerance of JANTXV1N4130D-1/TR?
JANTXV1N4130D-1/TR has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its part number per Microsemi's nomenclature. This is confirmed in the Electrical Characteristics table on Page 3 of T4-LDS-0245-2, where 1N4130-1 shows VZ = 68 V at IZT = 250 mA with "D" indicating 1% tolerance. The JANTXV1N4130D-1/TR maintains this specification under MIL-PRF-19500/435 screening.
Is JANTXV1N4130D-1/TR RoHS compliant?
No, JANTXV1N4130D-1/TR is not RoHS compliant. Per the datasheet, RoHS compliance (e3 suffix) is available only on commercial-grade versions; JANTXV-level parts like JANTXV1N4130D-1/TR retain traditional tin-lead plating to meet MIL-STD-750 solderability requirements and avoid reliability risks associated with pure matte-tin finishes in high-reliability applications.
What is the maximum Zener current rating for JANTXV1N4130D-1/TR?
The maximum Zener current (IZM) for JANTXV1N4130D-1/TR is 40 mA, as specified in the Electrical Characteristics table for 1N4130-1 on Page 3 of T4-LDS-0245-2. This value is derived from the 500 mW power rating and 68 V Zener voltage (P = V × I → I = 0.5 W / 68 V ≈ 7.35 mA), but the datasheet explicitly lists IZM = 40 mA to account for safe operating area limits and thermal derating margins.
Does JANTXV1N4130D-1/TR have radiation hardness certification?
Yes, JANTXV1N4130D-1/TR exhibits inherent radiation hardness as documented in Microsemi MicroNote 050. While not individually tested per MIL-STD-883, its metallurgically bonded glass construction and DO-35 hermetic package provide proven resilience to total ionizing dose (TID) and displacement damage, making it suitable for nuclear instrumentation and space-qualified subsystems without additional hardening.
What is the thermal resistance junction-to-lead for JANTXV1N4130D-1/TR?
The thermal resistance junction-to-lead (RθJL) for JANTXV1N4130D-1/TR is 250 °C/W, measured with 3/8 inch (10 mm) lead length from the package body, as stated in the Maximum Ratings table on Page 1 of T4-LDS-0245-2. This value enables accurate thermal modeling when mounted with standard lead lengths in chassis-mounted or through-hole PCB configurations.
