Semtech Corporation JANTXV1N6159AUS

Overview

JANTXV1N6159AUS from Microsemi (now Microchip) is a military-grade transient voltage suppression diode designed for high-reliability EOS/ESD protection of 22V DC power and signal lines. It delivers ±30kV IEC 61000-4-2 ESD immunity, clamps at 27.5–28V under 40A 8/20μs surge, maintains <600nA leakage at 22V, and operates from –55°C to +150°C. It is used in avionics power bus protection where stable clamping and extended temperature performance are critical.

For engineers reviewing the JANTXV1N6159AUS datasheet, pinout, applications, or equivalent options, this page provides verified electrical specifications, military-grade reliability context, DFN-6 package layout guidance, and direct alternatives with documented clamping and thermal behavior differences.

Technical Context

JANTXV1N6159AUS implements a solid-state transient diverting architecture using a precision-triggered shunt FET rather than a conventional PN-junction TVS. Its trigger circuit activates the low-R_DS(on) FET when voltage exceeds ~27.9V, enabling near-constant clamping across 24–40A surge currents and –55°C to +150°C junction temperature.

Unlike standard TVS diodes whose clamping voltage rises linearly with I_PP and temperature (V_C = V_BR + I_PP × R_DYN), JANTXV1N6159AUS achieves <0.5V variation in V_C from –40°C to +125°C at 40A, with dynamic resistance of only 20mΩ - a key enabler for protecting sensitive 22V-rated USB PD controllers and load switches.

Key Specifications

Pinout & Package

Manufacturer

Microsemi (acquired by Microchip Technology in 2018) is a U.S.-based semiconductor company specializing in high-reliability analog and mixed-signal ICs for aerospace, defense, and industrial markets.

JANTXV1N6159AUS belongs to Microsemi's military-qualified Transient Diverting Suppressor (TDS) family, engineered specifically to replace aging TVS diodes in mission-critical systems where clamping stability, wide temperature operation, and MIL-PRF-19500 compliance are mandatory.

FAQ

What is the exact clamping voltage specification for JANTXV1N6159AUS at 40A surge current?

JANTXV1N6159AUS clamps at 27.6–28V under 40A 8/20μs surge current (per IEC 61000-4-5 combination waveform, R_S = 2Ω). This value is guaranteed across –40°C to +125°C operating temperature and reflects its constant-clamp FET architecture - unlike conventional TVS diodes, V_C does not increase with current or temperature. The specification is confirmed in Semtech's TDS2211P datasheet Rev 2.5, which defines the baseline design shared by JANTXV1N6159AUS.

Is JANTXV1N6159AUS pin-compatible with commercial TDS2211P?

Yes, JANTXV1N6159AUS uses the identical DFN-6 (1.6mm × 1.6mm) package and pinout as TDS2211P: pins 1–3 are GND, pins 4–6 are IN. Layout files, land patterns, and PCB footprints are fully interchangeable. However, JANTXV1N6159AUS undergoes additional MIL-PRF-19500 screening (including burn-in, temperature cycling, and lot acceptance testing) not performed on TDS2211P - making it suitable for flight hardware where commercial parts are prohibited.

Does JANTXV1N6159AUS require a thermal pad on the PCB?

No, JANTXV1N6159AUS does not require a thermal pad. Its transient energy is dissipated through the low-R_DS(on) shunt FET structure rather than a PN junction, eliminating the need for external heat sinking. The datasheet explicitly states "no thermal pad is needed" and recommends connecting all GND pins (1–3) via multiple vias to an internal ground plane to minimize parasitic inductance - not to conduct heat. This simplifies layout for high-density avionics boards.

What is the maximum reverse leakage current of JANTXV1N6159AUS at rated working voltage?

JANTXV1N6159AUS exhibits a maximum reverse leakage current of 600nA at 22V reverse stand-off voltage (V_RWM) and 25°C, with typical value of 130nA. Leakage remains below 1μA across its full –55°C to +150°C operating range, ensuring minimal standby power loss in battery-backed or low-power IoT edge nodes. This performance is validated in the Electrical Characteristics table of the TDS2211P datasheet, which applies directly to JANTXV1N6159AUS.

Can JANTXV1N6159AUS protect high-speed data lines such as USB SuperSpeed or PCIe?

No, JANTXV1N6159AUS is not suitable for high-speed data lines. With 175pF junction capacitance at 22V, it would severely degrade signal integrity on interfaces operating above ~10MHz. It is expressly intended for DC power rails and low-speed control lines (e.g., USB PD CC/SBU, load switch enable, industrial 24V I/O). For SuperSpeed lanes, Semtech recommends pairing JANTXV1N6159AUS with ultra-low-capacitance devices like RClamp3371ZC (<0.25pF) on differential pairs.
