Product details
Overview
JANTXV1N5641A from Microchip Technology (formerly Microsemi) is a hermetically sealed, unidirectional transient voltage suppressor (TVS) diode in a DO-13 metal package, designed for high-reliability aerospace and military applications. It features a 19.8 V minimum breakdown voltage (VBR), 17.8 V rated standoff voltage (VWM), and clamps transients to ≤31.9 V at 47 A peak pulse current (IPP) under 10/1000 µs waveform - enabling robust protection of avionics power rails against ESD, EFT, and secondary lightning surges per IEC61000-4-2/-4-4/-4-5.
For engineers reviewing the JANTXV1N5641A datasheet, JANTXV1N5641A pinout, JANTXV1N5641A application, or JANTXV1N5641A equivalent, this part delivers MIL-PRF-19500/500 Class V qualification, radiation hardness per MicroNote 050, and guaranteed sub-100 ps response time - critical for protecting sensitive analog and digital circuitry in harsh electromagnetic environments without compromising signal integrity.
Technical Context
The JANTXV1N5641A operates as a unidirectional avalanche diode, entering controlled breakdown above its 17.8 V standoff voltage to shunt surge energy away from protected circuitry. Its hermetic DO-13 metal-glass package ensures stable thermal resistance (50 °C/W junction-to-lead) and operation across -55 °C to +175 °C ambient.
It delivers 1500 W non-repetitive peak pulse power at 25 °C with <100 ps response, supporting IEC61000-4-5 secondary lightning testing at 2 Ω, 12 Ω, and 42 Ω source impedances (Class 2–4). Standby leakage remains ≤5 µA at VWM, minimizing quiescent loading on low-power systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Rated Standoff) | 17.8 V - Maximum continuous reverse voltage before conduction; sets minimum operating rail compatibility. |
| VBR (Min @ IBR) | 19.8 V @ 1 mA - Guaranteed avalanche initiation threshold; ensures predictable clamping onset. |
| VC @ IPP | 31.9 V @ 47 A (10/1000 µs) - Peak clamped voltage during worst-case surge; defines maximum stress on downstream ICs. |
| PPP (Peak Pulse Power) | 1500 W - Sustains high-energy transients without failure; enables single-device protection for 24 V avionics buses. |
| ID @ VWM | ≤5 µA - Ultra-low leakage preserves battery life and avoids false triggering in high-impedance sensing paths. |
| Response Time | <100 ps - Near-instantaneous reaction prevents nanosecond-scale voltage overshoot from damaging CMOS inputs. |
| Operating Temp | -55 °C to +175 °C - Supports engine bay, radar, and flight control electronics without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N5642A | Higher VWM = 19.4 V, VBR min = 21.6 V, VC = 34.7 V @ 43 A - 2.6 V higher clamping voltage. | Better suited for 28 V systems where margin above nominal rail is larger; less suitable for 24 V rails near upper limit. | Select JANTXV1N5642A only when protected circuit has ≥25 V absolute maximum rating and requires tighter VWM margin. |
| JANTXV1N5640A | Lower VWM = 16.2 V, VBR min = 18.0 V, VC = 29.1 V @ 51.5 A - 2.3 V lower clamping voltage but reduced surge headroom. | Optimized for 18–20 V legacy avionics rails; may conduct during normal 24 V transients due to lower VWM. | Choose JANTXV1N5640A only for systems with strict clamping-voltage budgets and confirmed absence of 24 V operational overshoot. |
Compared with JANTXV1N5642A and JANTXV1N5640A, the JANTXV1N5641A uniquely balances 17.8 V VWM compatibility with 24 V nominal rails and 31.9 V clamping - making it the optimal choice for modern dual-voltage (18/24 V) avionics subsystems requiring MIL-qualified surge immunity without overdesign.

FAQ
What is the maximum clamping voltage of the JANTXV1N5641A under standard test conditions?
The JANTXV1N5641A exhibits a maximum clamping voltage (VC) of 31.9 V when subjected to a 10/1000 µs waveform at 47 A peak pulse current (IPP). This value is measured at 25 °C ambient and represents the highest voltage that will appear across the device during a standardized surge event - directly defining the peak stress imposed on downstream components. The JANTXV1N5641A maintains this clamping performance across its full operating temperature range.
Does the JANTXV1N5641A meet MIL-PRF-19500/500 requirements?
Yes, the JANTXV1N5641A is fully qualified to MIL-PRF-19500/500 Class V specifications, including rigorous environmental screening for temperature cycling, mechanical shock, vibration, and burn-in. The "JANTXV" prefix explicitly denotes compliance with these military performance requirements, and the device is manufactured and tested under Microchip's (formerly Microsemi) certified QML processes. Each JANTXV1N5641A lot traceability supports DoD documentation needs.
How does the hermetic DO-13 package of the JANTXV1N5641A improve reliability versus plastic TVS diodes?
The hermetic DO-13 metal-glass package of the JANTXV1N5641A eliminates moisture permeation and internal corrosion risks inherent in plastic packages, ensuring long-term parameter stability in high-humidity, salt-fog, or vacuum environments. Unlike plastic equivalents, the JANTXV1N5641A's sealed construction prevents delamination and parameter drift after thermal cycling - critical for 15+ year aerospace deployments. Its case-as-cathode design also minimizes parasitic inductance for faster transient response.
Can the JANTXV1N5641A be used for IEC61000-4-5 secondary lightning protection?
Yes, the JANTXV1N5641A is validated for IEC61000-4-5 secondary lightning protection up to Class 4 with 42 Ω source impedance, Class 3 with 12 Ω, and Class 2 with 2 Ω source impedance. Its 1500 W peak pulse power rating and sub-100 ps response enable reliable clamping of multi-kV surges without failure. The JANTXV1N5641A is routinely deployed in airborne avionics and ground vehicle electronics where such standards apply.
What is the standby leakage current specification for the JANTXV1N5641A at its rated standoff voltage?
The JANTXV1N5641A specifies a maximum standby leakage current (ID) of 5 µA at its rated standoff voltage (VWM) of 17.8 V and 25 °C ambient. This ultra-low leakage ensures minimal power loss in battery-backed or low-quiescent-current systems, and avoids false triggering in high-impedance monitoring circuits. The JANTXV1N5641A maintains leakage below 10 µA even at +125 °C, supporting wide-temperature operation without signal path interference.
