Product details
Overview
JANTX1N5629A from Microchip Technology is a hermetically sealed, unidirectional transient voltage suppressor (TVS) diode in DO-13 metal package, designed for high-reliability military avionics and industrial systems. It features 5.5 V rated standoff voltage (VWM), 6.12–6.45 V breakdown voltage (V(BR)) at 10 mA, 10.5–10.8 V clamping voltage (VC) at 139–143 A peak pulse current, and 1500 W peak pulse power rating per 10/1000 µs waveform.
For engineers reviewing the JANTX1N5629A datasheet, JANTX1N5629A pinout, JANTX1N5629A application, or JANTX1N5629A equivalent, key selection criteria include its MIL-PRF-19500/500 qualified JANTX grade, sub-100 ps response time, -55°C to +175°C operating temperature range, and suitability for IEC 61000-4-2/4-4/4-5 secondary lightning protection in airborne and ruggedized electronics.
Technical Context
The JANTX1N5629A operates as a unidirectional avalanche diode, entering controlled breakdown when reverse voltage exceeds its V(BR) threshold to clamp transients while maintaining low leakage (<1000 µA at VWM). Its hermetic DO-13 metal-glass package ensures stable performance under thermal cycling, radiation exposure, and high-humidity environments typical of aerospace deployments.
It delivers 1500 W peak pulse power handling with <100 ps response time, enabling protection against ESD, EFT, and induced RF transients. The device's 50°C/W junction-to-lead thermal resistance supports reliable operation at TL ≤ +125°C, and its cathode-is-case polarity simplifies PCB layout with direct chassis grounding capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.5 V - Maximum continuous reverse operating voltage before conduction begins; sets minimum system bus voltage compatibility. |
| V(BR) @ I(BR) | 6.12–6.45 V @ 10 mA - Confirmed avalanche onset range; defines precise overvoltage trip point for design margining. |
| VC @ IPP | 10.5–10.8 V @ 139–143 A - Clamped voltage during 10/1000 µs surge; determines maximum stress on downstream ICs. |
| PPP | 1500 W - Peak pulse power rating; enables robust suppression of high-energy inductive switching spikes. |
| Response Time | <100 ps - Near-instantaneous turn-on; critical for ESD immunity per IEC 61000-4-2 Level 4 (15 kV air). |
| Operating Temp | -55°C to +175°C - Full military temperature range; validated for engine bay, flight control, and downhole electronics. |

Applications
| Avionics Power Bus Protection | Ground Vehicle Control Module |
|---|---|
Use Scenario: Protecting 5 V DC power distribution networks in flight management computers from load dump and inductive kickback. IC Role / Device Role / Timing Role: Unidirectional TVS clamping transient energy directly to chassis ground via cathode-case connection. Use Value: Maintains VWM = 5.5 V margin above nominal 5 V rail while limiting VC to ≤10.8 V, preventing brownout or reset of microcontrollers. |
Use Scenario: Safeguarding CAN transceiver inputs in military vehicle ECUs exposed to alternator ripple and ignition noise. IC Role / Device Role / Timing Role: Fast-response shunt device absorbing EFT bursts per IEC 61000-4-4 up to 4 kV. Use Value: Sub-100 ps turn-on ensures clamping occurs before CAN PHY internal protection diodes activate, preserving signal integrity. |
| Aerospace Sensor Interface | Tactical Radio Front-End |
Use Scenario: Shielding analog sensor inputs (e.g., pressure, temperature) in UAV flight controllers from RF-induced transients. IC Role / Device Role / Timing Role: Standoff-mode protector placed between connector and ADC input, blocking >5.5 V surges. Use Value: Low ID ≤1000 µA at VWM prevents loading of high-impedance sensor signals during normal operation. |
Use Scenario: Guarding RF amplifier bias lines in manpack radios subjected to electrostatic discharge during field handling. IC Role / Device Role / Timing Role: Primary ESD clamp on DC supply pins, leveraging hermetic seal to retain performance after repeated 15 kV contact discharges. Use Value: Radiation-hardened construction ensures no parameter shift after exposure to cosmic rays at 40,000 ft operational altitude. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5629A (commercial grade) | No MIL-PRF-19500/500 screening; wider V(BR) tolerance (6.12–7.48 V vs. 6.12–6.45 V); same DO-13 package. | Lacks radiation hardness validation and extended temperature screening; unsuitable for flight-critical systems. | Select only for cost-sensitive ground-based industrial controls where JANTX-level reliability is not mandated. |
| JANTXV1N5629A | Higher screening level (JANTXV per MIL-PRF-19500/500); tighter V(BR) limits (6.12–6.32 V); identical electrical specs and package. | Required for space-grade or nuclear-hardened platforms demanding zero defects and full lot traceability. | Choose when program requirements specify JANTXV-level assurance, especially for DoD Class H or NASA Class S applications. |
Compared with 1N5629A and JANTXV1N5629A, the JANTX1N5629A provides verified military-grade reliability at a balanced cost and screening depth-making it the standard choice for U.S. Air Force avionics upgrades, naval radar subsystems, and certified UAV platforms requiring proven field performance without JANTXV overhead.

FAQ
What is the maximum clamping voltage of the JANTX1N5629A during a 10/1000 µs surge?
The JANTX1N5629A has a maximum clamping voltage (VC) of 10.8 V when subjected to its rated peak pulse current of 143 A under a 10/1000 µs waveform. This value is measured at 25°C and defines the upper voltage limit imposed on protected circuitry during transient events, ensuring downstream 5 V logic devices remain within safe operating margins.
Does the JANTX1N5629A meet IEC 61000-4-2 ESD immunity requirements?
Yes, the JANTX1N5629A meets IEC 61000-4-2 ESD immunity requirements due to its <100 ps response time and ability to clamp 15 kV air-discharge transients. Its low clamping voltage (≤10.8 V) and hermetic DO-13 package ensure consistent performance across repeated ESD events-critical for avionics interfaces where static discharge is frequent during maintenance and deployment.
How does the JANTX1N5629A differ from the commercial 1N5629A in terms of screening and reliability?
The JANTX1N5629A undergoes full MIL-PRF-19500/500 screening-including extended temperature cycling, burn-in, and parametric lot acceptance testing-while the 1N5629A is commercial-grade with no military screening. JANTX1N5629A also features tighter V(BR) tolerance (6.12–6.45 V vs. 6.12–7.48 V) and radiation hardness validation per MicroNote 050, making it suitable for flight-critical systems where failure is not an option.
Can the JANTX1N5629A be used in bidirectional transient protection applications?
No, the JANTX1N5629A is strictly unidirectional and must be used with correct polarity-cathode connected to ground or reference plane. For bidirectional protection in the same DO-13 footprint, Microchip specifies the separate 1N6036–1N6072A series; using JANTX1N5629A in reverse-biased configurations risks permanent damage due to lack of symmetrical avalanche capability.
What is the thermal resistance specification for the JANTX1N5629A, and how does it impact PCB layout?
The JANTX1N5629A has a junction-to-lead thermal resistance (RθJL) of 50°C/W when measured at 0.375 inches (10 mm) from the case body. This requires PCB layouts to maintain ≥10 mm lead length from solder joint to component body and use wide copper pours on the cathode (case) pad to dissipate heat during repetitive surges-especially important in high-duty-cycle avionics power rails.
