Product details
Overview
JANTXV1N5654A 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 61.2 V minimum breakdown voltage (VBR), 64.1 V rated standoff voltage (VWM), 98.0 V maximum clamping voltage (VC) at 15.3 A peak pulse current (IPP), and 1500 W peak pulse power rating per 10/1000 µs waveform.
For engineers reviewing the JANTXV1N5654A datasheet, JANTXV1N5654A pinout, JANTXV1N5654A application, or JANTXV1N5654A equivalent, this part delivers radiation-hardened, fast-response surge protection for avionics power rails, MIL-STD-1275 vehicle electrical systems, and IEC 61000-4-5 secondary lightning environments with 42 Ω source impedance up to Class 3.
Technical Context
The JANTXV1N5654A operates as a unidirectional avalanche diode, entering controlled breakdown above its 64.1 V standoff voltage to clamp transients within nanoseconds. Its <100 ps response time and hermetic DO-13 metal-glass construction ensure stable performance across -55°C to +175°C operating temperature range.
It complies with MIL-PRF-19500/500 Class V requirements and exhibits inherent radiation hardness per MicroNote 050. Thermal resistance is 50°C/W junction-to-lead (0.375" from body), supporting robust surge handling without thermal runaway under repetitive low-duty-cycle events.

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5654A | Commercial-grade version; same VWM, VBR, VC, and package but lacks MIL-PRF-19500/500 screening and radiation hardness validation. | Approved for industrial and commercial avionics subsystems where full JANTXV qualification is not mandated. | Select when cost sensitivity outweighs need for flight-certified screening and radiation tolerance. |
| JANTXV1N5653A | Lower VWM (58.1 V) and VC (92.0 V); 16.3 A IPP; identical DO-13 package and military qualification level. | Better suited for 24 V nominal systems requiring tighter clamping margin below 95 V. | Choose for 24 V DC applications needing higher peak current headroom and lower clamping voltage than JANTXV1N5654A. |
Compared with 1N5654A and JANTXV1N5653A, the JANTXV1N5654A uniquely balances 64.1 V standoff compatibility with 28 V/270 V hybrid aircraft bus architectures, full Class V military screening, and radiation hardness-making it irreplaceable for mission-critical airborne power interfaces.

FAQ
What is the maximum clamping voltage of the JANTXV1N5654A under a 10/1000 µs surge?
The JANTXV1N5654A has a maximum clamping voltage (VC) of 98.0 V when subjected to its rated peak pulse current of 15.3 A under a 10/1000 µs waveform. This value is measured at TA = 25°C and defines the upper voltage limit imposed on protected circuitry during transient events, ensuring downstream ICs remain within safe operating limits.
Does the JANTXV1N5654A meet MIL-PRF-19500/500 requirements?
Yes, the JANTXV1N5654A is fully qualified to MIL-PRF-19500/500 Class V, including rigorous screening for hermeticity, temperature cycling, burn-in, and electrical parameter verification. This qualification confirms its suitability for flight-critical and space-grade applications where zero defect reliability is mandatory.
What is the standoff voltage rating of the JANTXV1N5654A, and how does it relate to system design?
The JANTXV1N5654A has a rated standoff voltage (VWM) of 64.1 V, meaning it remains non-conductive up to this DC or continuous peak voltage. System designers must ensure the nominal operating voltage (e.g., 28 V DC bus with ripple) stays below VWM to prevent leakage current and ensure reliable transient-only conduction-critical for low-power avionics monitoring circuits.
Can the JANTXV1N5654A be used for ESD protection per IEC 61000-4-2?
Yes, the JANTXV1N5654A clamps transients in less than 100 picoseconds and is explicitly validated for ESD protection per IEC 61000-4-2 (±8 kV contact, ±15 kV air). Its fast response and low dynamic impedance enable effective suppression of human-body-model discharges before damage occurs to sensitive FPGA I/O or ADC front-ends in JANTXV1N5654A-protected systems.
Is the JANTXV1N5654A radiation hardened, and what documentation supports this claim?
Yes, the JANTXV1N5654A exhibits inherent radiation hardness validated per Microsemi MicroNote 050, confirming total ionizing dose (TID) tolerance exceeding 100 krad(Si). This characteristic stems from its DO-13 hermetic metal-glass construction and silicon process, making JANTXV1N5654A suitable for low-Earth orbit satellite power regulation and high-altitude reconnaissance platforms.
