Product details
Overview
JANTXV1N5652A from Microchip Technology (formerly Microsemi) is a hermetically sealed, unidirectional transient voltage suppressor (TVS) diode in DO-13 metal package, designed for high-reliability aerospace and military systems. It delivers 1500 W peak pulse power at 10/1000 µs, clamps transients to ≤85.0 V at 17.7 A, and operates across –55°C to +175°C - used to protect avionics power rails and signal lines against ESD, EFT, and secondary lightning surges per IEC61000-4-2/4-4/4-5.
For engineers reviewing the JANTXV1N5652A datasheet, JANTXV1N5652A pinout, JANTXV1N5652A application, or JANTXV1N5652A equivalent, key selection criteria include its 50.2 V rated standoff voltage (VWM), 55.8–58.9 V breakdown range (VBR), hermetic DO-13 package, MIL-PRF-19500/500 JANTXV qualification, and radiation-hardened performance per MicroNote 050.
Technical Context
The JANTXV1N5652A functions as a unidirectional avalanche-clamping TVS diode, activated only under reverse-biased overvoltage conditions. Its breakdown occurs at 55.8–58.9 V with 1 mA test current, and it clamps to ≤85.0 V when subjected to a 17.7 A 10/1000 µs surge - enabling robust protection of 48 V DC systems without forward conduction during normal operation.
It features a temperature coefficient of VBR of +0.104 %/°C and thermal resistance of 50 °C/W junction-to-lead, supporting stable operation at lead temperatures up to +125 °C. The cathode is internally connected to the metal case, enforcing fixed polarity and requiring proper PCB layout to avoid unintended grounding conflicts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Rated Standoff) | 50.2 V - maximum continuous reverse voltage before leakage exceeds 5 µA; sets upper limit for protected circuit's nominal DC rail. |
| VBR Min/Max | 55.8 V / 58.9 V @ 1 mA - defines guaranteed avalanche onset window; ensures predictable turn-on across temperature and unit variation. |
| VC @ IPP | ≤85.0 V @ 17.7 A - peak clamped voltage during 10/1000 µs surge; determines worst-case overvoltage stress on downstream ICs. |
| PPP | 1500 W - non-repetitive peak pulse power handling; enables survival of high-energy transients like induced lightning surges. |
| Response Time | <100 ps - near-instantaneous avalanche response; critical for suppressing ESD events before logic-level damage occurs. |
| Operating Temp | –55°C to +175°C - full military-grade temperature range; validated for engine bay, avionics bays, and space-qualified platforms. |
| Radiation Hardness | Inherently radiation hard per MicroNote 050 - no TID degradation or SEE-induced latch-up observed; suitable for low-earth orbit missions. |
Pinout & Package
Hermetically sealed DO-13 (DO-202AA) metal-glass package with axial leads: case serves as cathode terminal; polarity marked by diode symbol on body. Weight: 1.4 g. Solderable per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 2) | Transient current entry point during clamping | Connected to protected line; must be routed with low-inductance trace to minimize overshoot during fast transients. |
| Cathode (Lead 1 / Case) | Clamping return path | Internally bonded to metal case; requires direct, low-impedance connection to system ground plane - not chassis ground unless isolated. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional clamping | Blocks reverse surges only - preserves forward-biased functionality of downstream rectifiers or level-shifters in DC power paths. |
| MIL-PRF-19500/500 JANTXV qualification | Meets screening, testing, and traceability requirements for Class V (space-level) and Class H (high-reliability) applications. |
| Hermetic DO-13 metal package | Eliminates moisture ingress and long-term parameter drift - essential for 20+ year field life in sealed avionics enclosures. |
| IEC61000-4-5 compliance (Class 1–4) | Validated for secondary lightning protection with 2 Ω, 12 Ω, and 42 Ω source impedances - covers aircraft wiring harness coupling scenarios. |
| ESD/EFT immunity | Passes IEC61000-4-2 (±15 kV air, ±8 kV contact) and IEC61000-4-4 (4 kV burst) without derating - protects sensitive analog front-ends and data buses. |
Applications
| Aerospace Power Distribution | Avionics Signal Line Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMCJ58A | Surface-mount SMC package; 58 V VWM; 1500 W rating; 93.6 V clamping at 16.0 A. | Lacks hermetic seal and MIL-PRF-19500 qualification; not radiation hardened. | Select for commercial industrial designs where board space is constrained and radiation tolerance is unnecessary. |
| 1N5652A | Same DO-13 package and electrical specs, but commercial-grade (no JANTXV prefix); no MIL screening or traceability. | Not approved for flight-critical or space-qualified hardware; limited to ground-test or non-safety-critical subsystems. | Use only for prototyping or cost-sensitive terrestrial applications where military reliability is not mandated. |

FAQ
What is the standoff voltage (VWM) of the JANTXV1N5652A?
The JANTXV1N5652A has a rated standoff voltage (VWM) of 50.2 V, meaning it remains nonconductive below this reverse voltage while drawing less than 5 µA standby current. This value ensures compatibility with 48 V DC systems and provides margin against ripple and tolerance drift. The JANTXV1N5652A is specified to maintain this VWM across its full –55°C to +175°C operating range.
Is the JANTXV1N5652A suitable for IEC61000-4-5 secondary lightning protection?
Yes, the JANTXV1N5652A is validated for IEC61000-4-5 secondary lightning protection across all four classes when tested with 2 Ω, 12 Ω, and 42 Ω source impedances. Specifically, it supports Class 4 with 42 Ω (up to 1N5648A), Class 3 with 12 Ω (up to 1N5643A), and Class 2 with 2 Ω (up to 1N5642A). The JANTXV1N5652A's 1500 W peak pulse power and ≤85.0 V clamping enable reliable energy diversion without failure.
Does the JANTXV1N5652A have radiation hardness certification?
Yes, the JANTXV1N5652A is inherently radiation hard per Microsemi MicroNote 050 - a documented characterization confirming no total ionizing dose (TID) degradation or single-event effects (SEE) susceptibility up to mission-relevant fluences. This radiation hardness is process-based and does not require additional testing; the JANTXV1N5652A is routinely deployed in LEO satellite power systems and nuclear instrumentation.
What package type does the JANTXV1N5652A use, and how is polarity marked?
The JANTXV1N5652A uses a hermetically sealed DO-13 (DO-202AA) metal-glass package with axial leads. Polarity is marked by a diode symbol printed on the body, and the cathode is electrically connected to the metal case and Lead 1. This configuration mandates that the case be tied to the system's designated clamping reference (typically signal or power ground), not chassis, to prevent ground-loop issues. The JANTXV1N5652A's package meets MIL-STD-750 solderability requirements.
How does the JANTXV1N5652A differ from the commercial 1N5652A variant?
The JANTXV1N5652A differs from the commercial 1N5652A in three critical ways: it undergoes full MIL-PRF-19500/500 Class V screening (including burn-in, thermal cycling, and lot acceptance tests), carries full traceability and certificate-of-conformance documentation, and is qualified for operation up to +175°C lead temperature. The JANTXV1N5652A also includes radiation hardness validation absent in the 1N5652A. Both share identical electrical specs and DO-13 packaging.
