Product details
Overview
JANTX1N6156A 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, 40A peak pulse current (8/20μs), and stable 27.5–28V clamping across temperature and current range in a hermetically sealed DO-213AB package.
For engineers reviewing the JANTX1N6156A datasheet, pinout, applications, or equivalent options, this device is selected for aerospace, defense, and industrial systems requiring MIL-PRF-19500/537 qualified surge protection with guaranteed low dynamic resistance (20 mΩ) and minimal capacitance (175 pF at 22V).
Technical Context
JANTX1N6156A implements a solid-state shunt architecture using a precision-triggered surge-rated FET, not a conventional PN-junction TVS. Its clamping voltage remains nearly constant (27.5–28V) from 24A to 40A peak pulse current due to decreasing RDS(on), unlike linear VC = VBR + IPP × RDYN behavior in standard TVS diodes.
The device operates over −55°C to +150°C junction temperature, maintains <600 nA reverse leakage at 22V, and achieves 1120W peak pulse power handling. Its functional design targets direct replacement of legacy MIL-spec TVS diodes while delivering superior thermal stability and lower clamping variation versus temperature.

|---|---|
Use Scenario: Protecting VBUS lines in USB Type-C ports supporting up to 20V/5A PD negotiation. IC Role / Device Role / Timing Role: Primary shunt suppressor placed between VBUS and chassis ground, activated within nanoseconds of EOS event. Use Value: Maintains 27.5V clamping at 40A-prevents latch-up or gate oxide rupture in USB PD controller ICs rated for 30V absolute max. |
Use Scenario: Safeguarding analog input channels and digital I/O on programmable logic controllers exposed to factory floor surges. IC Role / Device Role / Timing Role: Front-end transient guard on 24V sensor supply rails and fieldbus communication lines (e.g., RS-485 bias rails). Use Value: Delivers ±1kV (1.2/50μs) surge immunity per IEC 61000-4-5 while holding leakage <600 nA-preserves measurement accuracy and avoids false triggers. |
| Aerospace Avionics Power Buses | Remote Metering & Smart Grid Sensors |
Use Scenario: Hardening 28V DC distribution networks in flight control computers and inertial navigation units. IC Role / Device Role / Timing Role: MIL-qualified transient clamp on primary power feeders, operating continuously across −55°C to +125°C. Use Value: Hermetic DO-213AB construction ensures zero parametric drift after 1000+ thermal cycles-critical for 20-year aircraft service life. |
Use Scenario: Protecting battery-backed real-time clocks and metrology ASICs in smart electricity meters deployed outdoors. IC Role / Device Role / Timing Role: Standby-mode protector on 22V backup rail, activated only during lightning-induced common-mode surges on AC mains coupling. Use Value: 175 pF capacitance prevents clock jitter; 20 mΩ dynamic resistance limits voltage rise to <100 mV during 100 ns EFT bursts (IEC 61000-4-4). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Semtech TDS2211P | DFN-6 surface-mount package; 1.6×1.6 mm footprint; 6-pin symmetric layout (3×IN, 3×GND); 175 pF capacitance same, but 20 mΩ RDYN confirmed. | Targeted for high-density USB-C and IoT PCBs; requires precise layout with multi-via GND stitching. | Select for space-constrained consumer or industrial designs where reflow assembly and board area savings outweigh through-hole reliability needs. |
| Littelfuse SP3022-01ETG | 0402 SMD package; 22V working voltage; ±30kV ESD; but only 12A IPP (8/20μs); 120 pF capacitance; no MIL qualification. | Designed for ultra-low-capacitance data-line protection (e.g., USB 3.0 SS lines), not power-rail duty. | Select only for non-military signal-line applications where peak current demand is <15A and MIL-spec compliance is unnecessary. |
Compared with JANTX1N6156A, TDS2211P offers identical electrical performance in a miniature DFN package ideal for modern layouts, while SP3022-01ETG trades surge capacity and qualification for size and speed-making JANTX1N6156A the sole choice for high-energy, mission-critical 22V rail protection.

FAQ
What is the maximum clamping voltage of JANTX1N6156A under full-rated surge conditions?
JANTX1N6156A clamps at 27.5–28 V when subjected to 40A peak pulse current (8/20μs waveform), per its datasheet test condition. This value is guaranteed across −55°C to +125°C operating temperature and reflects the device's constant-clamp FET architecture-not a fixed VBR + IPPRDYN relationship. The JANTX1N6156A maintains this tight clamping window even after repeated surges, making it suitable for safety-critical 22V rail protection.
Is JANTX1N6156A compatible with automated through-hole assembly processes?
Yes, JANTX1N6156A uses axial leads in a DO-213AB package with standard 0.030" lead diameter and 0.250" lead spacing, fully compatible with wave soldering, selective soldering, and hand-soldering per IPC-J-STD-001. Its glass passivation and hermetic seal ensure no moisture sensitivity or popcorning risk during reflow preheat stages. JANTX1N6156A is routinely used in high-reliability manufacturing lines for avionics and defense electronics.
How does JANTX1N6156A differ from commercial-grade 22V TVS diodes like SMAJ22A?
JANTX1N6156A differs fundamentally in construction, qualification, and clamping behavior: it is MIL-PRF-19500/537 screened with 100% lot testing, uses a triggered-FET architecture for flat clamping (27.5–28V), and features hermetic glass packaging. In contrast, SMAJ22A is a junction-TVSA with 35.5V typical clamping at 40A, no military screening, and plastic DO-214AC packaging. JANTX1N6156A delivers higher reliability, tighter parametric control, and superior thermal stability than SMAJ22A.
Can JANTX1N6156A be used for bidirectional protection on a 22V differential pair?
No, JANTX1N6156A is a unidirectional device configured as anode-to-cathode shunt suppressor, intended for single-ended 22V rail-to-ground protection. It does not provide symmetrical clamping for differential signals. For bidirectional 22V protection (e.g., RS-485 bias rails), a back-to-back configuration of two JANTX1N6156A units would be required-but this is not recommended due to timing skew and increased leakage. Use purpose-built bidirectional TVS arrays instead.
What is the reverse leakage current specification for JANTX1N6156A at maximum operating temperature?
JANTX1N6156A specifies a maximum reverse leakage current of 600 nA at 22V reverse standoff voltage and +125°C ambient temperature, per its Absolute Maximum Ratings table. This value is verified during MIL-PRF screening and remains stable over lifetime due to hermetic sealing. At room temperature (25°C), typical leakage is 130 nA-well below thresholds that could affect precision 22V sensor biasing or low-power standby circuits powered by JANTX1N6156A-protected rails.
