Product details
Overview
JANTX1N5662A from Microchip Technology (formerly Microsemi) is a hermetically sealed, unidirectional transient voltage suppressor (TVS) diode in DO-13 metal package, rated for 1500 W peak pulse power at 10/1000 µs, with 130 V standoff voltage (VWM), 144–152 V breakdown voltage (V(BR)), and 219 V maximum clamping voltage (VC) at 6.5 A peak pulse current - widely deployed in avionics power rail protection against secondary lightning surges per IEC61000-4-5.
For engineers reviewing the JANTX1N5662A datasheet, JANTX1N5662A pinout, JANTX1N5662A application, or JANTX1N5662A equivalent, this military-grade TVS offers verified ESD/EFT immunity per IEC61000-4-2/-4-4, radiation-hardened operation to −55°C to +175°C, and precise standoff/clamping margins critical for MIL-STD-704 aircraft power systems and high-reliability industrial control interfaces.
Technical Context
The JANTX1N5662A operates as a unidirectional avalanche diode, entering controlled breakdown when reverse voltage exceeds its 144–152 V V(BR) threshold at 1 mA, clamping transients to ≤219 V within <100 ps. Its hermetic DO-13 metal-glass package ensures stable thermal resistance (50°C/W junction-to-lead) and immunity to humidity-induced parameter drift.
Designed for military qualification per MIL-PRF-19500/500, the "JANTX" prefix confirms compliance with screening levels including temperature cycling, burn-in, and lot acceptance testing - enabling use in Class 1–4 secondary lightning protection (IEC61000-4-5) with 2 Ω, 12 Ω, and 42 Ω source impedances.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Rated Standoff Voltage) | 130 V - maximum continuous reverse operating voltage before leakage exceeds 5 µA; sets minimum system rail voltage compatibility. |
| V(BR) @ I(BR) | 144–152 V @ 1 mA - guaranteed avalanche onset range; defines minimum overvoltage trigger threshold under DC stress. |
| VC @ IPP | 219 V @ 6.5 A - peak clamped voltage during 10/1000 µs surge; determines worst-case voltage seen by protected ICs. |
| PPP (Peak Pulse Power) | 1500 W - maximum non-repetitive surge energy handling capability; validates robustness against IEC61000-4-5 Level 4 events. |
| Response Time | <100 ps - time from transient onset to clamping engagement; ensures protection of fast-edge digital logic and analog sensors. |
| Operating Temperature | −55°C to +175°C - full military temperature range; supports engine bay, radar, and flight-critical electronics without derating. |
| Package | DO-13 (DO-202AA) - hermetically sealed metal-glass case with cathode-connected case; enables high-reliability through-hole mounting and solderability per MIL-STD-750. |
Pinout & Package
DO-13 (DO-202AA) hermetically sealed metal-glass package with axial leads; cathode terminal electrically connected to case and marked by diode symbol on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 2) | Transient current entry point during reverse surge | Connected to protected line (e.g., 28 VDC aircraft bus); carries full 6.5 A surge current during clamping. |
| Cathode (Lead 1 / Case) | Clamping reference and return path | Internally bonded to metal case; must be connected to low-impedance ground plane to maintain ≤219 V VC under surge. |
Key Features
| Feature | Design Value |

Applications
| Aircraft Power Distribution | Avionics Data Bus Protection |
|---|---|

Use Value: Maintains bit error rate (BER) <10⁻¹² under ±8 kV ESD (IEC61000-4-2) without adding signal delay or reflection. |
| Ground Vehicle Control Units | Industrial Motor Drive Inputs |
Use Scenario: Shielding engine control unit (ECU) power inputs from inductive switching spikes generated by fuel injectors and solenoids. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 12/24 V supply rails, coordinated with upstream fuses and downstream LDOs. Use Value: Extends ECU service life by eliminating cumulative oxide damage from sub-100 ns turn-off spikes in automotive ISO 7637-2 Pulse 1/2a. |
Use Scenario: Protecting programmable logic controller (PLC) analog input modules from 2 kV surges induced by nearby VFD switching noise. IC Role / Device Role / Timing Role: Front-end transient suppressor on 4–20 mA current loop terminals, placed before precision op-amp front ends.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N5662A | Higher screening level (JANTXV vs JANTX): includes additional radiation testing and extended temperature burn-in. | Required for spaceflight and nuclear-hardened systems where TID >100 krad(Si) or single-event latch-up (SEL) immunity is mandated. | Select JANTXV1N5662A only when mission-critical radiation assurance beyond standard JANTX is contractually specified. |
| 1N5662A (commercial grade) | No MIL-PRF-19500 screening; not subjected to temperature cycling, lot acceptance tests, or hermeticity validation. | Suitable for non-military industrial prototypes or cost-sensitive ground test equipment where full qualification is unnecessary. | Choose 1N5662A for bench validation or non-flight hardware; JANTX1N5662A remains mandatory for production avionics. |
Compared with JANTXV1N5662A, the JANTX1N5662A delivers identical electrical specs and DO-13 packaging but omits radiation-specific screening - reducing cost and lead time while retaining full MIL-STD-461/704 compliance. Versus commercial 1N5662A, it adds traceable lot-level reliability data and hermetic seal verification essential for field-deployed systems.

FAQ
What is the clamping voltage of JANTX1N5662A under a 10/1000 µs surge?
The JANTX1N5662A exhibits a maximum clamping voltage (VC) of 219 V when subjected to its rated peak pulse current of 6.5 A under the standardized 10/1000 µs waveform. This value is measured per JEDEC test conditions and guarantees the protected circuit will not experience more than 219 V during such a transient - a critical parameter for ensuring downstream IC survival in avionics power systems.
Is JANTX1N5662A suitable for bidirectional transient suppression?
No, JANTX1N5662A is a unidirectional TVS diode designed for DC-biased applications like 28 V aircraft buses. It conducts only in reverse breakdown and blocks forward current. For bidirectional protection (e.g., AC signal lines or RS-485), Microchip's 1N6036–1N6072A series in the same DO-13 package must be used instead - JANTX1N5662A lacks symmetrical clamping capability.
What does the "JANTX" prefix signify for JANTX1N5662A?
The "JANTX" prefix on JANTX1N5662A certifies full compliance with MIL-PRF-19500/500, including rigorous screening: temperature cycling, steady-state bias life testing, and lot acceptance tests. It distinguishes this part from commercial 1N5662A and higher-tier JANTXV versions - confirming suitability for military procurement without requiring requalification.
Can JANTX1N5662A replace JANTX1N5661A in an existing design?
JANTX1N5662A has a higher VWM (130 V vs 121 V) and V(BR) (144–152 V vs 135–143 V) than JANTX1N5661A, making it unsuitable as a direct drop-in replacement unless the system's operating voltage margin allows the increased standoff. Substituting JANTX1N5662A may cause premature clamping or increased leakage; verify VWM compatibility with actual rail voltage before redesign.
What is the thermal resistance specification for JANTX1N5662A?
JANTX1N5662A has a junction-to-lead thermal resistance (RθJL) of 50°C/W when measured at 0.375 inches (10 mm) from the case, per the datasheet's maximum ratings table. This value is critical for calculating junction temperature rise during repetitive surge events and confirms the DO-13 package's ability to dissipate heat effectively in high-density PCB layouts with minimal copper area.
