Product details
Overview
JANTX1N5635A from Microchip Technology (formerly Microsemi) is a hermetically sealed, unidirectional transient voltage suppressor diode in a DO-13 metal package, designed for high-reliability military and aerospace applications. It provides 1500 W peak pulse power handling at 10/1000 µs, clamps transients to ≤17.3 V at 87 A, and operates across –55°C to +175°C - commonly used in avionics power rail protection against ESD, EFT, and secondary lightning surges per IEC61000-4-2/4-4/4-5.
For engineers reviewing the JANTX1N5635A datasheet, JANTX1N5635A pinout, JANTX1N5635A application, or JANTX1N5635A equivalent, this page delivers verified electrical specs, military qualification context, DO-13 terminal configuration, real-world surge protection use cases, and validated alternative parts for design-in and obsolescence mitigation.
Technical Context
The JANTX1N5635A is a unidirectional avalanche TVS diode with cathode tied to case, optimized for fast transient suppression in harsh environments. Its breakdown voltage is 10.8–11.4 V at 1 mA, standoff voltage is 9.72 V, and maximum clamping voltage is 17.3 V at 87 A peak pulse current - enabling robust protection of 9–10 V logic or analog rails without false triggering.
It meets MIL-PRF-19500/500 Class H requirements under JANTX qualification, features hermetic DO-13 packaging with tin-lead plating, and exhibits a temperature coefficient of breakdown voltage of +0.078 %/°C - ensuring stable clamping performance across extended temperature ranges in airborne and ground-based military systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500 W @ 10/1000 µs - sustains high-energy surges without failure in avionics and vehicle electronics. |
| Standoff Voltage (VWM) | 9.72 V - sets maximum continuous reverse operating voltage before leakage exceeds 5 µA. |
| Breakdown Voltage (VBR) | 10.8–11.4 V @ 1 mA - defines onset of controlled avalanche conduction during overvoltage events. |
| Clamping Voltage (VC) | 17.3 V @ 87 A IPP - limits downstream voltage stress on protected ICs during worst-case transients. |
| Response Time | <100 ps - enables effective suppression of ESD (IEC61000-4-2) and fast EFT bursts (IEC61000-4-4). |
| Operating Temperature | –55°C to +175°C - supports deployment in engine bays, radar modules, and space-grade subsystems. |
| Package | DO-13 (DO-202AA), hermetically sealed metal-glass - ensures long-term reliability in high-humidity, radiation-prone, or vacuum environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5635A (commercial) | No MIL-PRF-19500/500 screening; same VWM (9.72 V), VC (17.3 V), and DO-13 package. | Lacks radiation hardness verification and extended temperature validation; unsuitable for flight-critical systems. | Select only for non-mission-critical ground test equipment or cost-sensitive prototypes where JANTX-level assurance is not required. |
| JANTXV1N5635A | Higher screening level (MIL-PRF-19500/500 Class K); tighter VBR tolerance (±5% vs ±6% for JANTX); enhanced lot traceability. | Required for spaceflight hardware and nuclear command systems where zero-defect reliability is mandated. | Choose when full JANTXV qualification - including burn-in, thermal cycling, and radiation testing - is specified in the system's reliability plan. |
Compared with 1N5635A and JANTXV1N5635A, the JANTX1N5635A delivers certified military-grade robustness at lower cost than JANTXV, while offering guaranteed radiation tolerance and extended temperature performance unavailable in commercial variants - making it the optimal balance for avionics and tactical platform designs.

FAQ
What is the standoff voltage of the JANTX1N5635A and how does it relate to system design?
The JANTX1N5635A has a rated standoff voltage (VWM) of 9.72 V, meaning it remains nonconductive below this reverse voltage with leakage ≤5 µA. In system design, VWM must exceed the maximum continuous operating voltage of the protected line - for example, selecting JANTX1N5635A for a nominal 9 V rail ensures reliable blocking during normal operation while allowing clamping at 17.3 V during transients. This prevents false triggering and preserves signal integrity in analog or digital circuits powered from that rail.
Is the JANTX1N5635A pin-compatible with other DO-13 TVS diodes like the 1N5635A?
Yes, the JANTX1N5635A shares identical DO-13 mechanical dimensions, lead configuration, and cathode-to-case polarity marking with the commercial 1N5635A. Both have anode on lead 2 and cathode electrically bonded to lead 1 and the metal case. No PCB layout change is needed when upgrading from 1N5635A to JANTX1N5635A - however, JANTX qualification adds screening, traceability, and extended temperature validation not present in the commercial part.
Does the JANTX1N5635A meet IEC61000-4-5 Class 3 lightning surge requirements?
Yes, the JANTX1N5635A is explicitly rated for IEC61000-4-5 Class 3 secondary lightning protection with a 2 Ω source impedance, as confirmed in the datasheet's APPLICATIONS section. Its 1500 W peak pulse power and 17.3 V clamping voltage at 87 A enable it to limit surge voltages to safe levels for downstream components in avionics and military vehicle systems subjected to this standardized threat profile.
How does the JANTX1N5635A's radiation hardness benefit satellite applications?
The JANTX1N5635A is inherently radiation-hardened per Microsemi MicroNote 050, meaning it exhibits minimal parametric shift and no functional failure under total ionizing dose (TID) exposure typical in low-earth orbit. This allows it to protect sensor interfaces and power rails in satellite telemetry modules without derating or redundancy - a critical advantage over commercial TVS diodes that may degrade or fail after cumulative radiation exposure.
What is the thermal resistance specification for the JANTX1N5635A and how does it affect PCB layout?
The JANTX1N5635A has a junction-to-lead thermal resistance of 50°C/W when measured at 0.375″ (10 mm) from the case, and 110°C/W junction-to-ambient on FR4 with 4 mm² copper pads and 1 mm wide × 25 mm long traces. To maintain reliability at high pulse repetition rates, designers should ensure adequate copper area around the cathode (case) connection and avoid narrow traces - especially in high-temperature environments where derating per Figure 3 applies.
