Product details
Overview
JANTX1N5664A from Microchip Technology (formerly Microsemi) is a hermetically sealed, unidirectional transient voltage suppressor (TVS) diode in DO-13 metal package, designed for high-reliability military and aerospace applications. It features 1500 W peak pulse power (10/1000 µs), 146 V rated standoff voltage (VWM), 246 V maximum clamping voltage (VC) at 5.8 A peak pulse current (IPP), and sub-100 ps response time - enabling protection against ESD (IEC61000-4-2), EFT (IEC61000-4-4), and secondary lightning surges (IEC61000-4-5) in avionics and ruggedized control systems.
For engineers reviewing the JANTX1N5664A datasheet, JANTX1N5664A pinout, JANTX1N5664A application, or JANTX1N5664A equivalent, this part delivers MIL-PRF-19500/500 qualified surge suppression with hermetic DO-13 packaging, radiation-hardened performance per MicroNote 050, and validated compliance with Class 1–4 IEC61000-4-5 surge levels under 2–42 Ω source impedances.
Technical Context
The JANTX1N5664A operates as a unidirectional avalanche diode, entering breakdown at minimum 162 V (VBR @ 1 mA) and clamping transients to ≤246 V (VC) while conducting up to 5.8 A (IPP). Its DO-13 metal-glass package provides 50 °C/W junction-to-lead thermal resistance and supports operation from –55 °C to +175 °C.
It is explicitly qualified to MIL-PRF-19500/500 as a JANTX-grade device, with tighter parameter tolerances than commercial "1N5664" variants. The cathode is internally connected to the case, requiring proper grounding of the metal body during PCB layout to ensure correct polarity and optimal clamping performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500 W (10/1000 µs waveform); sustains single high-energy surges without degradation in avionics power rails. |
| Standoff Voltage (VWM) | 146 V; ensures non-conduction during normal 120–140 VDC system operation, preventing leakage or power loss. |
| Clamping Voltage (VC) | 246 V @ 5.8 A IPP; limits downstream voltage stress to safe levels for 200 V-rated components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N5664A | Higher screening level (JANTXV vs JANTX); includes additional environmental stress screening (ESS) and extended lot acceptance testing. | Required for spaceflight missions and nuclear command systems where zero latent defects are mandated. | Select JANTXV when full MIL-PRF-19500/500 Appendix A compliance is contractually required. |
| 1N5664A (commercial) | No military qualification; wider VBR tolerance (162–187 V vs 162–171 V); not radiation-hardened. | Suitable only for non-safety-critical industrial equipment with benign operating environments. | Use only for cost-sensitive prototypes or non-mission-critical subsystems lacking radiation or reliability requirements. |

FAQ
What is the maximum clamping voltage of JANTX1N5664A under standard test conditions?
The JANTX1N5664A has a maximum clamping voltage (VC) of 246 V when subjected to its rated peak pulse current of 5.8 A using the 10/1000 µs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream components remain within their absolute maximum ratings.
Is JANTX1N5664A suitable for bidirectional transient suppression?
No, JANTX1N5664A is a unidirectional TVS diode, intended for DC or single-polarity AC applications where reverse conduction must be blocked during normal operation. For bidirectional protection in the same DO-13 package, Microchip offers the 1N6036–1N6072A series - JANTX1N5664A must be used with correct polarity orientation and case grounding to function as specified.
Does JANTX1N5664A require external heat sinking in typical PCB layouts?
No, JANTX1N5664A does not require external heat sinking for transient suppression duty, as it is not rated for continuous power dissipation. Its 1 W DC power rating applies only to brief forward conduction events; thermal design focuses on minimizing lead length and maximizing copper area for surge current paths - the 50 °C/W junction-to-lead resistance is optimized for pulsed operation, not steady-state heating.
How does the hermetic DO-13 package of JANTX1N5664A improve reliability over plastic alternatives?
The hermetic DO-13 metal-glass package of JANTX1N5664A prevents moisture ingress, outgassing, and ionic contamination - eliminating corrosion, parameter drift, and latent failures common in plastic-packaged TVS devices under thermal cycling, humidity, or vacuum. This construction is mandatory for avionics, space, and nuclear applications where field failure is unacceptable.
Can JANTX1N5664A be used for ESD protection per IEC61000-4-2?
Yes, JANTX1N5664A is explicitly validated for ESD protection per IEC61000-4-2 due to its <100 ps response time and ability to clamp 8 kV contact/15 kV air discharge transients without degradation. Its 1500 W peak rating exceeds typical ESD event energy, and its hermetic construction ensures consistent performance across temperature and lifetime - making JANTX1N5664A suitable for protecting high-value avionics I/O ports.
