Product details
Overview
JANTX1N5654A 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 61.2 V minimum breakdown voltage (VBR), 55.1 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 at 10/1000 µs waveform.
For engineers reviewing the JANTX1N5654A datasheet, JANTX1N5654A pinout, JANTX1N5654A application, or JANTX1N5654A equivalent, this part delivers sub-100 ps response time, -55°C to +175°C operating temperature range, and MIL-PRF-19500/500 JANTX qualification - critical for lightning surge protection (IEC 61000-4-5 Class 3, 2 Ω source), ESD immunity (IEC 61000-4-2), and inductive switching transient suppression.
Technical Context
The JANTX1N5654A operates as a unidirectional avalanche diode, entering controlled breakdown when reverse voltage exceeds its 61.2–71.3 V VBR range at 1 mA test current. Its clamping action limits transient-induced voltage to ≤98.0 V while conducting up to 15.3 A peak pulse current under standardized 10/1000 µs surge conditions.
Constructed in a hermetic DO-13 (DO-202AA) metal-glass package with cathode connected to case, it achieves 50°C/W junction-to-lead thermal resistance and supports forward surge current of 200 A (8.3 ms half-sine). Its temperature coefficient of VBR is +0.105%/°C, ensuring stable breakdown behavior across extended temperature extremes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTX1N5653A | Lower VWM (55.1 V → 50.2 V), lower VC (92.0 V), higher IPP (16.3 A) | Better suited for 48 V nominal systems with tighter clamping margin requirements | Select when system operating voltage is ≤45 V and lower clamping voltage is prioritized over standoff margin. |
| JANTX1N5655A | Higher VWM (55.1 V → 66.4 V), higher VC (113 V), lower IPP (12.0 A) | Targeted for 72 V battery-fed avionics or hybrid-electric vehicle subsystems | Choose for 60–70 V DC rails where higher standoff prevents nuisance conduction during load dump transients. |

FAQ
What is the standoff voltage (VWM) specification for JANTX1N5654A?
The JANTX1N5654A has a rated standoff voltage (VWM) of 55.1 V, meaning it remains non-conductive under continuous reverse bias up to this level while maintaining standby current ≤5 µA. This value is derived from the JEDEC-standardized 1N5654A series and confirmed in Microchip's T4-LDS-0096 Rev. 3 datasheet. The JANTX1N5654A must be selected so that VWM ≥ maximum steady-state operating voltage of the protected line.
Does JANTX1N5654A meet MIL-PRF-19500/500 requirements?
Yes, the JANTX1N5654A is explicitly qualified to MIL-PRF-19500/500 per the "JANTX" prefix designation in its part number and is listed in the Features section of the T4-LDS-0096 datasheet. This includes rigorous screening for temperature cycling, hermeticity, burn-in, and electrical parameter verification - making it suitable for U.S. Department of Defense and NATO procurement programs.
What is the maximum clamping voltage (VC) of JANTX1N5654A under surge conditions?
The JANTX1N5654A exhibits a maximum clamping voltage (VC) of 98.0 V when subjected to its rated 15.3 A peak pulse current (IPP) under the standard 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 - a key parameter for ensuring downstream IC survival.
Is JANTX1N5654A compatible with lead-free soldering processes?
No - the JANTX1N5654A uses tin-lead (SnPb) plating on all external metal surfaces per MIL-STD-750 Method 2026, and its maximum solder temperature rating is 260°C for 10 seconds. Lead-free reflow profiles exceeding 260°C or prolonged exposure will compromise hermetic seal integrity and void qualification. For RoHS-compliant alternatives, consult Microchip's SMCJ or SMCG surface-mount families.
How does the temperature coefficient affect JANTX1N5654A's breakdown voltage?
The JANTX1N5654A has a positive temperature coefficient of VBR of +0.105%/°C, meaning its breakdown voltage increases linearly with junction temperature. At +125°C, VBR rises ~10.5% above its 25°C value (61.2–71.3 V), enhancing margin against false triggering at high ambient temperatures - a critical advantage in engine-mounted or downhole electronics where thermal stability is essential.
