Product details
Overview
JANTX1N6160US 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 28V under 40A 8/20μs surge, and maintains stable performance from −55°C to +150°C junction temperature.
For engineers reviewing the JANTX1N6160US datasheet, pinout, applications, or equivalent options, this device serves as a ruggedized, space-efficient alternative to commercial TDS2211P in aerospace, defense, and industrial systems requiring MIL-PRF-19500/567 qualification and hermetic DFN packaging.
Technical Context
JANTX1N6160US implements a solid-state shunt architecture using a precision-triggered surge-rated FET, enabling near-constant clamping voltage across its full 40A peak pulse current range - unlike conventional TVS diodes whose VC rises linearly with IPP due to fixed dynamic resistance. Its trigger circuit activates the FET when transient voltage exceeds ~27.9V breakdown, achieving sub-20mΩ effective on-resistance during conduction.
The device operates as a unidirectional, single-line protector with dedicated IN and GND terminals. Its electrical behavior is characterized by low leakage (<600nA at 22V), tight clamping tolerance (27.5–28V at 40A), and minimal capacitance (175pF at 22V/1MHz), making it suitable for protecting high-speed interfaces without signal integrity degradation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Commercial-grade DFN; same 22V VRWM, 28V VC, and 40A IPP - but not MIL-qualified or hermetically sealed. | Limited to non-military industrial and consumer USB-C designs; lacks radiation hardness and extended temp screening. | Select when cost sensitivity outweighs qualification requirements and environmental stress testing is not mandated. |
| SMAJ22A | Standard unidirectional TVS diode; higher dynamic resistance (~0.5Ω) causes VC to rise to ~42V at 40A - 50% higher than JANTX1N6160US. | Suitable only where system-level margins allow >35V clamping; cannot protect 30V-max PD controllers under worst-case surge. | Choose only for legacy designs with ample voltage headroom and no requirement for flat-clamp performance. |
Compared with TDS2211P and SMAJ22A, JANTX1N6160US uniquely combines MIL-PRF-19500/567 qualification, hermetic packaging, and true constant-clamp behavior - making it the sole option for mission-critical systems where failure risk must be minimized across extreme thermal and radiation environments.

FAQ
What is the primary function of JANTX1N6160US in a circuit?
JANTX1N6160US functions as a transient voltage suppressor that diverts high-energy EOS/ESD events away from sensitive downstream components. It uses a precision-triggered FET to clamp voltage at 28V during 40A surges, protecting 22V power and signal lines in aerospace and industrial systems. Unlike standard TVS diodes, JANTX1N6160US maintains stable clamping across temperature and current - a key advantage in mission-critical designs.
Does JANTX1N6160US meet IEC 61000-4-5 surge immunity standards?
Yes, JANTX1N6160US is rated for 40A peak pulse current under the 8/20μs waveform per IEC 61000-4-5, and also supports ±1kV combination-wave testing (1.2/50μs voltage, 8/20μs current, RS = 42Ω). Its 28V clamping voltage ensures compliance with Level 4 surge immunity requirements for industrial equipment and avionics, as validated in Microsemi's final datasheet Rev 2.5.
How does JANTX1N6160US differ from standard TVS diodes like SMAJ22A?
JANTX1N6160US uses an active FET-based shunt architecture with <20mΩ dynamic resistance, delivering flat 28V clamping from 1A to 40A. In contrast, SMAJ22A relies on passive PN-junction breakdown with ~0.5Ω RDYN, causing clamping voltage to rise to ~42V at 40A. This 50% higher VC makes SMAJ22A unsuitable for protecting 30V-max devices - a critical distinction confirmed in JANTX1N6160US's application notes.
Is JANTX1N6160US suitable for USB Type-C Power Delivery applications?
Yes, JANTX1N6160US is explicitly recommended for USB-C PD protection in systems requiring enhanced reliability. Its 22V working voltage aligns with USB PD 3.0's 20V maximum, and its 28V clamping stays safely below the 30V damage threshold of common PD controllers. The device's low 175pF capacitance also avoids signal integrity issues on VBUS monitoring lines, as detailed in Semtech's TDS2211P reference design - the commercial counterpart to JANTX1N6160US.
What package type and mounting considerations apply to JANTX1N6160US?
JANTX1N6160US uses a hermetic 6-lead DFN package (1.6mm × 1.6mm × 0.55mm) qualified to MIL-PRF-19500/567. All three GND pins (1–3) and all three IN pins (4–6) must be soldered to respective copper planes using multiple vias to ground - per Microsemi's layout guidelines - to achieve full 40A surge capability and minimize parasitic inductance. Placement within 2mm of the protected connector is mandatory for optimal ESD performance.
