Product details
Overview
JANTXV1N5647A 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 aerospace systems. It features 35.1 V minimum breakdown voltage (VBR), 31.6 V rated standoff voltage (VWM), and clamps transients to ≤56.4 V at 26.5 A peak pulse current (IPP) under 10/1000 µs waveform - enabling robust protection against ESD, EFT, and secondary lightning surges per IEC61000-4-2/4-4/4-5.
For engineers reviewing the JANTXV1N5647A datasheet, JANTXV1N5647A pinout, JANTXV1N5647A application, or JANTXV1N5647A equivalent, this device delivers verified 1500 W peak pulse power handling, sub-100 ps response time, and radiation-hardened operation across –55°C to +175°C - critical for mission-critical inductive switching, airborne power bus, and MIL-PRF-19500/500-compliant designs.
Technical Context
The JANTXV1N5647A operates as a unidirectional avalanche diode with cathode tied to case, requiring correct polarity orientation in series with protected lines. Its 50°C/W junction-to-lead thermal resistance supports sustained surge dissipation when mounted with ≥10 mm lead length from body, and its 0.100%/°C temperature coefficient of VBR ensures predictable voltage drift over temperature.
It meets MIL-PRF-19500/500 Class V requirements for JANTXV-grade devices, including hermetic sealing, tin-lead plating per MIL-STD-750 Method 2026, and 1.4 g mass tolerance. The DO-13 package enables through-hole mounting with solderability up to 260°C for 10 s, and its 100% tested 1500 W rating applies only at TL = 25°C with ≤0.01% repetition rate.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Rated Standoff) | 31.6 V - maximum continuous reverse voltage before leakage exceeds 5 µA; sets upper limit for protected line DC operating voltage |
| VBR @ IBR | 35.1–37.1 V @ 1 mA - guaranteed avalanche initiation range; defines minimum clamping threshold under transient stress |
| VC @ IPP | ≤56.4 V @ 26.5 A (10/1000 µs) - peak clamped voltage seen by downstream circuitry during worst-case surge |
| Peak Pulse Power | 1500 W - maximum single-event energy absorption capability without failure; validated per Figure 1 derating curve |
| Response Time | <100 ps - enables effective suppression of ESD events (IEC61000-4-2) and fast-rising RF-induced transients |
| Operating Temp | –55°C to +175°C - qualified for extended-range military and aerospace environments without derating |
| Package | DO-13 (DO-202AA) - hermetically sealed metal-glass case with cathode-connected case and axial leads |

Use Scenario: Protecting LNA inputs and PA bias lines in manpack radios from ESD during field handling and antenna coupling. IC Role / Device Role / Timing Role: Low-capacitance unidirectional TVS placed directly at SMA connector feedthrough to minimize stub inductance. Use Value: Hermetic DO-13 package prevents parameter shift in humid desert environments; 5 µA ID @ VWM avoids loading sensitive RF bias networks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N5646A | Lower VWM (29.1 V), lower VC (49.9 V @ 29 A), same DO-13 package and MIL-PRF-19500/500 screening | Better suited for 24 V systems where tighter clamping margin is required below 50 V | Select when protecting 24 V rails with stricter downstream voltage limits; verify VBR min (29.7 V) remains above max operating voltage. |
| JANTXV1N5648A | Higher VWM (34.8 V), higher VC (61.9 V @ 24 A), identical thermal and environmental specs | Preferred for 36 V avionics buses or systems requiring higher standoff margin before conduction | Choose for 36 V nominal systems needing ≥10% headroom above VWM; confirm downstream ICs tolerate 61.9 V transient clamp. |
Compared with JANTXV1N5646A and JANTXV1N5648A, the JANTXV1N5647A provides optimal balance for 28 V aerospace power buses - delivering 31.6 V standoff with 56.4 V clamping, minimizing both false triggering and overvoltage risk to downstream FPGAs and ADCs.

FAQ
What is the maximum clamping voltage of the JANTXV1N5647A under standard test conditions?
The JANTXV1N5647A has a maximum clamping voltage (VC) of 56.4 V when subjected to a 10/1000 µs peak pulse current of 26.5 A at TA = 25°C. This value is measured across the device terminals and represents the highest voltage seen by protected circuitry during worst-case surge events - a key parameter for ensuring downstream ICs remain within absolute maximum ratings. The JANTXV1N5647A maintains this performance across its full military temperature range when properly mounted.
Does the JANTXV1N5647A meet MIL-PRF-19500/500 requirements?
Yes, the JANTXV1N5647A is fully qualified to MIL-PRF-19500/500 Class V as a JANTXV-grade device. This includes hermetic DO-13 packaging, tin-lead plating per MIL-STD-750 Method 2026, 100% screening for temperature cycling, burn-in, and parametric testing, and compliance with all electrical and mechanical specifications defined in the standard. The "JANTXV" prefix explicitly denotes this qualification level, distinguishing it from commercial or JAN-grade variants.
How does the DO-13 package of the JANTXV1N5647A impact thermal performance?
The DO-13 package of the JANTXV1N5647A provides a junction-to-lead thermal resistance of 50°C/W when measured at 10 mm from the case, enabling efficient heat transfer to PCB copper or chassis ground. Its hermetic metal-glass construction avoids polymer-based thermal bottlenecks found in plastic packages, supporting reliable 1500 W pulse dissipation in high-vibration aerospace mounts. For optimal thermal management, the cathode (case) must be soldered to a ≥4 mm² copper pad per MIL-STD-202G Method 108.
Can the JANTXV1N5647A be used for bidirectional transient suppression?
No, the JANTXV1N5647A is a unidirectional TVS diode with cathode tied to case and marked polarity - it conducts only in reverse breakdown and blocks forward current. For bidirectional protection in the same DO-13 footprint, Microchip offers the 1N6036–1N6072A series, which are explicitly designed as symmetrical devices. Using JANTXV1N5647A in bidirectional configurations risks forward conduction and failure; always match device polarity to system grounding architecture.
What is the standby leakage current of the JANTXV1N5647A at its rated standoff voltage?
The JANTXV1N5647A exhibits a maximum standby leakage current (ID) of 5 µA when biased at its rated standoff voltage (VWM) of 31.6 V and measured at TA = 25°C. This ultra-low leakage ensures minimal power loss in always-on avionics subsystems and avoids loading sensitive reference or bias networks. Leakage remains below 10 µA across the full –55°C to +125°C operating range, as confirmed by MIL-PRF-19500/500 screening data.
